When Your Pool Is Losing Water: Fixing Skimmer Leaks
Fixing a leaking pool skimmer requires identifying the source and applying the appropriate repair method. Here’s a quick overview:
- Turn off pool pump before inspection
- Identify leak location using dye test or visual inspection
- Lower water level below the skimmer if needed
- Contact CL Wizard for professional assessment and permanent repair
- Avoid DIY fixes that typically fail within one season
If you’re noticing your pool water level constantly dropping, wet spots around the deck, or having trouble with pump operation, your skimmer could be the culprit. Skimmer leaks account for approximately 60% of all pool leak calls, making them the most common source of water loss in swimming pools.
For property managers overseeing high-value residential or commercial pools in South Florida, these leaks are more than just a nuisance. They waste water, chemicals, and can lead to structural damage if left untreated. A leaking pool skimmer can cause a pool to lose up to 1/2 inch of water per day – that’s hundreds of gallons of treated water escaping weekly.
While DIY fixes using epoxy putties or silicone sealers might seem tempting, these typically provide only temporary relief. Most of these repairs fail within a season, especially in areas with ground movement or freeze/thaw cycles. For concrete pools specifically, the issue often stems from the “cold joint” where the plastic skimmer meets the concrete pool shell – a vulnerability that requires specialized treatment.
Instead of gambling with temporary fixes, professional assessment by CL Wizard using their proprietary polyvinyl injection technology provides a permanent solution without requiring pool drainage or extensive demolition. Their specialized equipment can precisely locate and seal leaks while your pool remains operational, saving valuable time and resources.

Understanding Pool Skimmers and Their Vulnerabilities
Ever wonder what that little opening at the side of your pool does? It’s your pool skimmer – the unsung hero of pool maintenance! Skimmers aren’t just leaf catchers; they’re the frontline defenders of your pool’s filtration system. They work by gently drawing water from the surface, capturing leaves and debris in a basket before they sink, and channeling clean water toward your pump and filter.
For South Florida’s commercial properties and multi-unit buildings, these modest components are absolutely essential. But here’s the problem – they’re also the most vulnerable part of your pool structure.
The issue comes down to what engineers call a “cold joint” – the meeting point between different materials. Your plastic skimmer housing meets concrete or gunite, creating a junction that’s naturally prone to separation over time. It’s like trying to permanently glue rubber to stone – challenging under the best circumstances.
This vulnerability exists because of:
– Materials expanding and contracting at different rates
– Florida’s notorious sandy soil shifting beneath the pool
– Vibrations from people walking on pool decks
– Pressure changes from water levels and pump operation
The numbers don’t lie – skimmer leaks account for approximately 60% of all pool leak service calls. When you understand the stresses these components face daily, that statistic starts to make perfect sense.
Why Skimmers Are Prone to Leaks
That plastic-to-concrete joint creates an inherent weakness, especially in South Florida properties. Several factors make this vulnerability worse:
Ground Movement and Soil Shifts
Florida’s sandy soil is constantly on the move. As Marco Aurelio, CL Wizard’s founder, often explains to concerned property managers: “Concrete doesn’t bend, but the ground beneath it never stops shifting. This creates constant stress at connection points like skimmers.”
Even tiny ground movements can create hairline cracks where your skimmer meets the pool shell. These may seem insignificant at first, but they’re the beginning of bigger problems.
Chemical Wear and Tear
Pool chemicals – especially chlorine – are tough on plastic components. Over time, they can make your skimmer housing brittle and prone to cracking. Many maintenance teams inadvertently accelerate this damage by storing chlorine tablets directly in the skimmer basket.
“We see this mistake all the time,” notes a CL Wizard technician. “Storing tablets in the skimmer saves a few minutes but costs thousands in repairs down the road.”
High-Traffic Deck Vibration
Commercial and multi-family pools see far more activity than residential ones. All that foot traffic creates vibrations that transfer directly to your skimmer housing, gradually loosening its connection to the surrounding concrete. Think of it as slowly wiggling a tooth loose – eventually, it gives way.
Temperature Fluctuations
While South Florida doesn’t see freezing temperatures, daily temperature changes still cause materials to expand and contract at different rates. This constant thermal cycling gradually weakens the skimmer-concrete bond, creating tiny spaces where water can escape.
Signs Your Skimmer Is the Source
Catching a skimmer leak early can save thousands in water costs and prevent structural damage. Here’s how to tell if your skimmer is the culprit behind your water loss:
Consistent Water Level Drop
If your pool loses about half an inch of water daily and then stabilizes right at or below the skimmer opening, you’ve likely found your leak. This pattern occurs because once water drops below the damaged area, the leaking stops – a telltale sign of skimmer issues.
Soggy Spots Around the Skimmer
Notice dampness, unusual algae growth, or particularly lush grass near your skimmer? Water is probably escaping through the housing. In commercial properties with deck pavers, you might see pavers settling or shifting near the skimmer – another red flag.
Pump Performance Issues
Air bubbles appearing in your pump basket or trouble maintaining prime often points to a skimmer leak. When skimmers leak, they don’t just lose water – they can draw air into your system, causing the pump to run inefficiently or lose prime altogether.
Dye Test Shows Suction
Professional leak detection using food coloring or specialized dye provides visual confirmation. If you see dye being pulled into cracks around the skimmer, you’ve found your leak. This simple but effective test is why professionals like CL Wizard can pinpoint problems so accurately.
As documented in scientific research on leak patterns, skimmer leaks typically follow predictable patterns based on construction methods and the pool’s age. Understanding these patterns helps CL Wizard target their detection and repair efforts with remarkable precision.
When it comes to fixing a leaking pool skimmer, knowing exactly where and why the leak is occurring makes all the difference between a temporary patch and a permanent solution.
Diagnosing, Not DIY: The Proven Path to Fixing a Leaking Pool Skimmer
When it comes to fixing a leaking pool skimmer in your commercial or multi-family property, trying DIY solutions is like putting a band-aid on a broken pipe. It might slow things down momentarily, but the real problem continues beneath the surface.
At CL Wizard, we’ve seen countless property managers frustrated after wasting time and money on temporary fixes. That’s why we approach skimmer leaks differently – starting with professional diagnosis before jumping to solutions. Our team combines old-school visual inspection with cutting-edge detection technology to map the exact path water takes through your concrete structure.
“We’re not just confirming a leak exists,” explains one of our technicians. “We’re creating a complete picture of the water’s journey so we can apply our polyvinyl solution precisely where it will create a permanent seal.”
Our comprehensive detection process includes a thorough system evaluation, hydrostatic isolation testing to separate different sections, and advanced technology like sonar and ultrasonic equipment. We also provide detailed documentation for your insurance and maintenance records – something DIY approaches simply can’t offer.
| Detection Method | Best For | Limitations | Accuracy |
|---|---|---|---|
| Visual Inspection | Surface cracks, obvious separation | Cannot detect internal or hidden leaks | Moderate |
| Dye Testing | Confirming suspected leak points | Requires relatively still water | High for visible leaks |
| Pressure Testing | Plumbing connections, skimmer throat | Cannot identify structural cracks | Very high for plumbing |
| Ultrasonic Detection | Hidden leaks behind concrete | Requires specialized equipment | Extremely high |
| CL Wizard Comprehensive | All leak types | None – combines all methods | Highest available |
Fixing a Leaking Pool Skimmer With Precision Testing
Fixing a leaking pool skimmer begins with knowing exactly what you’re dealing with. Our multi-step diagnostic approach has been refined specifically for commercial properties where downtime means unhappy residents and lost revenue.
We start with simple but crucial water level testing over 24-48 hours. If your pool’s water level drops and then mysteriously stabilizes right at or below the skimmer opening, that’s a strong indication your skimmer is the culprit. This basic step helps us rule out other potential issues before focusing our attention.
Next comes our dye application testing – a surprisingly revealing technique that works while your pool remains open. One Miami Beach condo manager told us, “CL Wizard identified our skimmer leak without shutting down our pool during peak season. Their dye test clearly showed where water was escaping, and they fixed it the same day.”
When dealing with particularly stubborn or hidden leaks, we bring out our ultrasonic microphone technology. This amazing tool can actually hear water moving through cracks too small to see with the naked eye.
“Traditional companies often miss the subtle leaks that cause significant damage over time,” notes Marco Aurelio, our founder. “Our ultrasonic equipment can detect water movement through cracks as small as a human hair.”
For more on these advanced techniques, check out our guide to Detecting Leaks in Swimming Pools.
Locating the Exact Crack in Concrete Skimmer Housings
Once we’ve confirmed your skimmer is leaking, we need to pinpoint exactly where the problem is occurring. Skimmer leaks typically happen in one of four areas, each with its own telltale signs.
The skimmer mouth – where the faceplate meets the pool wall – is the most common culprit. This area constantly experiences changing water levels and is subject to vibration from deck traffic. You might notice visible separation between the skimmer face and pool wall, moisture on the deck around the skimmer, or dye being pulled into the seam during testing.
The skimmer throat connecting the mouth to the main body can develop leaks from settling that misaligns components, vibration from water flow, or deteriorating gaskets. Meanwhile, the skimmer bowl/body itself might crack due to ground movement, occasional cold snaps, or impact damage during construction.
Don’t forget the plumbing connections! These joints can loosen over time, with gaskets deteriorating from chemical exposure, while shifting soil places stress on rigid connections.
For especially challenging cases, we use specialized endoscope cameras that slip into the skimmer plumbing system, letting us inspect areas hidden from view without any destructive demolition. This technology gives us a clear picture of internal components so we know exactly what we’re dealing with before applying our unique polyvinyl solution.

The CL Wizard Solution vs. Traditional Skimmer Repairs
When it comes to fixing a leaking pool skimmer, property managers of commercial and multi-family buildings face a critical choice: opt for temporary fixes that will need repeating, or invest in CL Wizard’s permanent solution that addresses the root of the problem.
The difference isn’t just about how long the repair lasts. It’s about a fundamentally different approach to concrete leak repair. While traditional methods simply patch visible cracks, CL Wizard’s innovative technology tackles the actual pathway water takes through concrete.
What makes CL Wizard’s polyvinyl injection process so effective? First, our team conducts a precision diagnosis using advanced detection equipment to map exactly how water is moving through your concrete. We then identify strategic injection points that will intercept this water migration.
Our proprietary polyvinyl solution is truly remarkable – it starts as a water-like liquid that follows the exact path of the leak, then undergoes a molecular change into a flexible rubber that permanently seals the entire leak pathway. Best of all, we can verify the success of our repair while your pool remains fully operational.
This innovative approach wasn’t developed by accident. CL Wizard founder Marco Aurelio specifically created this technology to address the unique challenges of concrete water infiltration in South Florida’s demanding environment.
“Traditional methods fight against concrete’s natural properties,” explains Marco. “Our technology works with concrete’s porosity, using it to deliver our solution precisely where water is traveling.”
For property managers throughout South Florida, the benefits of our approach are substantial:
No pool drainage required – your amenity stays open for residents while we work. No demolition or reconstruction needed, saving you from costly and disruptive concrete work. Our repairs are permit-free, shaving weeks off project timelines. You’ll see immediate results as leaks are sealed during the first application. Best of all, our permanent solution creates a flexible rubber seal that accommodates future concrete movement.
Fixing a Leaking Pool Skimmer — Traditional Methods (and Their Limits)
Before diving deeper into the CL Wizard solution, let’s understand why traditional skimmer repair methods so often leave property managers disappointed.
The most common approach involves applying epoxy putty to visible cracks around the skimmer. While this might seem effective initially, these repairs typically fail within 6-12 months as concrete naturally shifts. These rigid patches can only address visible cracks, not the entire water pathway, and they require lowering the pool water level, disrupting normal operations. Many property managers also complain about epoxy discoloring over time, creating unsightly patches around their skimmers.
Silicone sealant application is another common but flawed approach. These sealants adhere poorly to wet surfaces, degrade quickly when exposed to pool chemicals and Florida sunshine, and require regular reapplication – typically every season. Most importantly, silicone stays on the surface, unable to penetrate into concrete to seal internal pathways.
Some repair companies offer foam injection, but this creates rigid foam that cracks with normal concrete movement. The foam expands unpredictably, potentially causing further damage, and is difficult to apply precisely at the concrete-skimmer interface. This method typically requires extensive preparation and pool drainage.
The most extreme traditional solution involves complete skimmer replacement – requiring extensive demolition, pool drainage, permits, inspections, and extended pool closure (typically 7-14 days). At $2,000-$5,000 per skimmer, it’s an expensive fix that’s still vulnerable to the same fundamental issues.
A property manager from a Boca Raton condominium shares: “We tried traditional repairs on our skimmers three times in five years. Each time, the leak returned within months. CL Wizard fixed it permanently in 2019, and we haven’t had a problem since.”
Why CL Wizard’s Polyvinyl Injection Is Different
The key to fixing a leaking pool skimmer permanently lies in understanding how water actually moves through concrete. Our proprietary polyvinyl injection technology addresses this fundamental issue in a way no other method can.
Our solution has the same viscosity as water, allowing it to follow the exact path water takes through concrete’s microscopic channels. This ensures our solution reaches every part of the leak pathway, not just the visible entry or exit points.
“Water finds the path of least resistance through concrete,” explains Marco Aurelio. “Our solution follows that exact same path, then transforms into a permanent, flexible seal.”
After injection, our polyvinyl solution undergoes a remarkable change. It begins as a water-like liquid that penetrates even microscopic pathways, then begins a molecular conversion process. Within hours, it transforms into a rubber-like elastomer – a flexible material that maintains its seal even as concrete shifts and moves. This cure is permanent and resistant to pool chemicals and UV exposure.
Perhaps most impressive for busy property managers is that this entire process can be performed while your pool remains filled and operational. This means no disruption to resident amenities, no expensive water replacement costs, no chemical rebalancing required, and no extended closure periods.
Our technology is particularly valuable for properties throughout South Florida, from Miami to Jupiter. It accommodates the constant soil movement that defeats rigid repairs in Florida’s sandy soil. It resists humidity effects in our tropical climate and withstands tropical conditions through heavy rains and hurricane seasons. Unlike many sealants, our polyvinyl doesn’t degrade with the intense sun exposure common in our region.
For commercial and multi-family properties where pool amenities are crucial to resident satisfaction and property value, CL Wizard’s approach offers the best advantages. Our comprehensive South Florida coverage ensures prompt service throughout the region, keeping your property’s amenities in perfect working order.
Preventing Future Skimmer Leaks in Concrete Pools
While CL Wizard provides the most effective permanent solution for existing skimmer leaks, prevention remains the best strategy for commercial property managers. Implementing a proactive maintenance program can help identify potential issues before they develop into costly problems.
The key to maintaining leak-free skimmers starts with understanding that prevention is an investment, not an expense. As one South Florida property manager told us, “The hour we spend each week checking our skimmers has saved us thousands in emergency repairs and resident complaints.”
Routine skimmer inspections should become part of your maintenance team’s regular schedule. A weekly visual check of skimmer mouths can catch early signs of separation before they develop into major leaks. Monthly examinations of the surrounding deck areas will help identify moisture or settling that often precedes a leak. Quarterly, take time for a more detailed inspection of skimmer bodies and plumbing connections, paying special attention after heavy rain events or unusual ground movement.
One of the most overlooked causes of premature skimmer deterioration comes from improper chemical storage practices. Never store chlorine tablets directly in skimmer baskets—this concentrates harsh chemicals exactly where you don’t want them. Instead, use floating dispensers that distribute chemicals evenly throughout the pool. Maintaining balanced water chemistry isn’t just good for swimmers; it significantly reduces the corrosive effects on your skimmer components and plumbing.
The concrete deck surrounding your skimmers can provide early warning signs of potential problems. Monitor for deck settlement by watching for cracks radiating from skimmer locations or uneven settling of deck sections nearby. Any visible gaps between the deck and skimmer face plates should be addressed promptly—they’re often the first sign of movement that will lead to leaks. For properties with significant soil instability, professional soil stabilization might be worth considering before leaks develop.
“What we often see is that property managers wait until water is literally bubbling up through the deck before they call us,” says Marco Aurelio of CL Wizard. “By then, the damage is extensive. The properties that bring us in for annual inspections catch issues when they’re small and much less expensive to address.”
CL Wizard offers professional preventative maintenance programs specifically designed for commercial and multi-family properties. These include annual comprehensive inspections of all skimmers and vulnerable concrete joints, with early intervention using their polyvinyl injection at the first sign of potential leaks. This proactive approach typically reduces overall pool maintenance costs by 30-40% over five years—a significant savings for property budgets.

Property-Manager Checklist for Leak-Free Skimmers
As a property manager responsible for pool amenities, maintaining leak-free skimmers requires consistent attention. The most successful managers follow a structured approach that becomes second nature to their maintenance teams.
Weekly maintenance should include thorough cleaning of skimmer baskets—not just emptying leaves, but inspecting for cracks or damage. Check the skimmer mouth for any visible separation or cracks, and scan the deck area around skimmers for signs of moisture. Verify the water is at the proper level (middle of the skimmer opening) and document these readings. A simple water level log can help identify slow leaks early, often before they’re visible.
On a monthly basis, expand your inspection to examine skimmer weir doors for proper operation—they should swing freely without sticking. Check all visible gaskets and seals for signs of deterioration, and monitor pump performance for any signs of air infiltration (often indicated by bubbles in the pump basket). Also be attentive to chemical usage—a sudden increase in chemical demand often indicates water is leaking and being replaced with fresh water that needs treatment.
“Our quarterly reviews saved us from a major leak disaster,” shares a property manager from a Jupiter condominium. “We noticed slight settling around one skimmer during our routine check, called CL Wizard for an inspection, and they found an internal crack that would have eventually caused major deck damage.”
These quarterly professional reviews should include testing skimmer plumbing connections for leaks and evaluating soil stability around the pool structure. It’s also a good time to update your emergency contact protocol for leak response—make sure everyone knows exactly who to call when signs of a leak appear.
Annual planning should include scheduling a comprehensive CL Wizard leak inspection and preventative treatment. This is also the perfect time to review your water usage data (many properties can track this through utility bills) to identify potential slow leaks that might otherwise go unnoticed. Use this opportunity to update maintenance protocols based on inspection findings and train any new staff on proper skimmer maintenance procedures.

Frequently Asked Questions about Fixing a Leaking Pool Skimmer
How long does a CL Wizard skimmer repair last?
When fixing a leaking pool skimmer, longevity is a primary concern for property managers. Unlike traditional repairs that often fail within months, CL Wizard’s polyvinyl injection creates a truly permanent solution.
“We’ve been tracking our earliest commercial pool repairs for over a decade now,” Marco Aurelio proudly shares. “Even in properties with significant ground movement, our skimmer repairs have maintained complete integrity.”
What makes this possible? The fundamental difference is in our approach. Rather than merely filling visible cracks like traditional methods, our polyvinyl solution creates a comprehensive, flexible seal throughout the entire water pathway. This addresses the root cause rather than just treating symptoms.
For South Florida property managers overseeing condominiums, hotels, and commercial buildings, this permanence translates to significant long-term savings – both in repair costs and precious maintenance time. No more scheduling annual “touch-ups” or explaining to residents why the pool is leaking again.
Will pool operations need to stop during the repair?
One of the most remarkable advantages of choosing CL Wizard for fixing a leaking pool skimmer is that your pool remains operational throughout the entire repair process. Our innovative polyvinyl injection technology works underwater, eliminating the disruption of draining and refilling.
This benefit is particularly valuable for:
– Hotels and resorts where pool amenities directly impact guest satisfaction
– Condominiums and apartments where residents expect continuous access
– Commercial properties where pool closure would affect revenue
– Properties during peak season when closure would be most disruptive
The repair process typically requires only sectioning off the immediate work area for a few hours. Most residents or guests won’t even notice work is underway.
A property manager from a West Palm Beach hotel recently told us: “CL Wizard repaired three leaking skimmers during our busiest season without closing our pool for even an hour. Our guests were completely unaware that repairs were happening.”
When should an entire skimmer be replaced instead of repaired?
While CL Wizard’s proprietary technology can successfully repair the vast majority of skimmer leaks, there are rare situations where replacement might be necessary:
When a skimmer has suffered severe structural damage – perhaps being crushed or completely shattered due to extreme ground movement or construction accidents – replacement may be unavoidable. Similarly, with very old equipment (30+ years) where discontinued parts prevent proper function of weirs, baskets, or equalizers, a full replacement might make sense. Lastly, during major pool redesign projects that fundamentally change the circulation system requirements, new skimmers might be part of the overall plan.
However, we’ve found these situations are remarkably uncommon. “In our experience, less than 5% of skimmer issues actually require replacement,” explains our senior technician. “Most companies recommend replacement because they don’t have access to our polyvinyl technology.”
Even in seemingly extreme cases, CL Wizard can often provide solutions that avoid complete replacement. Our engineers evaluate each situation individually, recommending the most cost-effective approach that delivers permanent results.
If you’re uncertain whether your property’s skimmer needs repair or replacement, we offer complimentary assessments for commercial and multi-family properties throughout South Florida. Our goal is always to provide the least disruptive, most permanent solution possible.
