A damaged swimming pool surface can lead to significant water loss, higher utility bills, and underlying structural deterioration. West Key Builders restores the beauty, safety, and functionality of your property with proven crack assessment and repair solutions tailored for concrete, gunite, and customized pool installations.
Professional pool crack repair services in London Ontario are essential to restoring the long-term beauty and functional integrity of your outdoor or indoor aquatic space. Discovering a crack in your pool can be a frustrating and elusive problem for property owners. While pools are structurally designed to withstand the test of time and water pressure, cracks can inevitably develop over the years due to a variety of environmental and physical factors. These include ongoing ground movement, seasonal temperature fluctuations, improper original construction, or simply a lack of regular proactive maintenance.
When investigating a leak or visible separation, it is common to find these cracks appearing in high-stress areas. They often emerge in corners, directly at the waterline tile, near pipe openings and skimmer throats, or around underwater lighting fixtures. Understanding where and why these fractures occur is the first step toward a permanent solution. At West Key Builders, we prioritize an accurate diagnosis to ensure our repairs address the root cause of the structural stress, rather than merely covering the surface symptom.
We understand the importance of maintaining a pristine and fully functional swimming pool for your family, guests, or commercial patrons.

Fixing a swimming pool involves more than just applying waterproof putty. A reliable repair demands a systematic approach to ensure that the water pressure and chemical environment do not degrade the seal over time. Our methodical process is designed to deliver lasting results.
Our technicians conduct a meticulous inspection using advanced tools to detect even the smallest cracks. We leave no stone unturned, ensuring precise identification of the leak’s actual source before discussing repair options.
Once the crack is identified, we create a repair strategy tailored to your pool’s unique structure. We not only repair the visible crack but also investigate root causes to prevent future issues.
We use only industry-approved products such as high-strength epoxies and polyurethanes that withstand water pressure, chemical exposure, and environmental wear. These materials ensure long-term performance.
Our experts carry out each repair with precision. We restore structural strength, often using concrete staples or injection techniques, while seamlessly blending the repaired surface with your existing pool finish.
Pool cracks, if ignored or left untreated, can lead to costly secondary water damage, severe inefficiencies in heating and circulation, and significant structural failures. Water escaping through a cracked shell can wash away the supporting soil beneath the pool, creating voids that lead to further settling and more severe cracking. Timely repair not only protects your substantial financial investment but also ensures a safe, hygienic, and enjoyable swimming environment for years to come.
Leaks can also result in noticeably higher monthly water bills and unnecessary mechanical stress on your pool’s filtration and pumping systems. By forcing your equipment to work harder to maintain water levels and chemical balance, unresolved leaks accelerate the wear and tear on expensive hardware. Detecting and sealing cracks early prevents the need for much more extensive demolition or rebuilding in the future. It contributes directly to a more sustainable, cost-effective maintenance plan for your property.
When selecting a contractor to manage your aquatic infrastructure, experience and transparency are vital. We take pride in delivering pool crack repair services in London Ontario that property owners can rely on without hesitation. You can learn more about our operational history and commitment to quality by reviewing the West Key Builders team page.
At West Key Builders, our approach does not stop at fixing the current damage. We firmly believe in implementing long-term preventative strategies to significantly reduce the chances of new cracks reappearing. This comprehensive mindset includes proactive structural inspections, monitoring the integrity of the surrounding concrete deck, and advising on essential seasonal pool care. For general exterior maintenance insights, clients can routinely read our concrete works blog.
Our team actively educates pool owners on vital best practices. We emphasize the importance of maintaining consistent water chemistry, as highly acidic water can slowly etch and weaken the plaster over time. We also discuss how to properly manage the expansion joints between your pool coping and the surrounding deck, ensuring that water does not seep behind the shell during winter freezes. By combining expert pool crack repair services in London Ontario with thorough preventative education, we help you protect your oasis against the unpredictable Canadian climate.
Understanding how pool cracks are diagnosed, repaired, and prevented can help you make informed decisions about your property. Review our detailed answers below, or check our general concrete repair FAQs for broader exterior property advice.
Surface cracks, often called craze or spider cracks, typically appear in the plaster or gel coat and are usually very shallow, thin, and do not leak water. Structural cracks, however, extend deeply into the concrete or gunite shell of the pool. These deeper fissures often run through the tile line, down the walls, or across the floor, and are the primary cause of unexplained water loss. A professional inspection is the safest way to accurately distinguish between a cosmetic blemish and a structural threat.
The bucket test is a simple DIY method to determine if your pool is leaking or just losing water to natural evaporation. You place a bucket filled with water on a pool step so the water level inside the bucket matches the pool’s water level outside the bucket. Mark both levels. Wait 24 hours. If the pool water has dropped significantly lower than the water inside the bucket, you likely have a leak that requires our pool crack repair services in London Ontario.
The timeline heavily depends on the severity and location of the crack. Minor epoxy injections or surface patching can often be completed in a single day. More extensive structural repairs involving concrete staples, grinding, filling, and replastering may take several days to ensure proper curing and sealing. During our initial assessment, we provide a clear, customized timeline so you know exactly when you can safely resume swimming.
Not always. Many minor cracks can be successfully repaired underwater using specialized hydraulic cements, marine epoxies, and underwater curing agents. However, for severe structural cracks that require structural staples, deep injection, or extensive surface preparation, draining the pool partially or completely is necessary to ensure the repair materials bond correctly and achieve maximum strength. We determine the safest, most efficient method during the inspection.
The freeze-thaw cycle is a primary cause of structural damage in our region. When water seeps into tiny, unnoticeable surface cracks or behind the pool shell, it expands as it freezes during the winter. This expansion exerts tremendous pressure on the concrete, widening the crack. When it thaws, more water enters the enlarged space, repeating the cycle. Professional pool crack repair services in London Ontario break this destructive cycle by thoroughly sealing vulnerable areas before winter arrives.
We utilize a combination of high-grade, industry-approved materials depending on the pool’s construction. This includes high-pressure polyurethane foams that expand to fill voids, structural epoxy resins that bond stronger than the concrete itself, hydraulic cement for rapid water-stop applications, and carbon fiber or steel staples to bridge and stabilize severe structural fractures against further movement.
While we make every effort to tint our repair materials and plaster to match your existing pool finish, achieving a 100% flawless colour match is challenging due to the natural fading, chemical wear, and UV exposure the older surrounding plaster has experienced over the years. We prioritize the structural integrity and waterproof seal of the repair, while blending the aesthetics as closely as possible to maintain your pool’s visual appeal.
It is normal for a swimming pool to lose about a quarter of an inch to half an inch of water per day due to natural evaporation, splashing, and filter backwashing, especially during hot, dry, and windy summer days. If you are consistently losing more than an inch of water a day, or if you notice you have to refill the pool much more frequently than in previous seasons, it is highly recommended to seek professional leak detection and repair.
Yes, chronic chemical imbalance can severely damage a pool over time. If the water is consistently too acidic (low pH), it will aggressively etch and dissolve the calcium in the plaster and concrete shell. This weakens the surface, making it porous, brittle, and highly susceptible to cracking under normal ground pressure. Maintaining balanced water chemistry is a critical preventative measure that protects the structural integrity of your pool.
Pool staples, or torque lock staples, are strong metal or carbon-fiber braces used to physically stitch a severe structural crack together. We cut small slots perpendicular to the crack, insert the staples, and tension them to pull the crack tightly closed. This prevents the crack from opening further due to soil movement or hydrostatic pressure. We then cover the staples and the crack with hydraulic cement and plaster for a smooth, permanent finish.
DIY pool putties and sealants can act as a temporary emergency patch to slow down a severe leak, but they are rarely a permanent solution for structural cracks. They do not address the underlying tension or ground movement causing the fracture. Over time, the crack will likely expand beyond the putty, or the putty will degrade under chemical exposure. Professional pool crack repair services in London Ontario provide a permanent, root-cause solution.
No, completely draining a pool for the winter is actually very dangerous for the structure. The water inside the pool provides necessary outward hydrostatic pressure that counteracts the inward pressure from the freezing, expanding soil surrounding the shell. If the pool is empty, the expanding winter soil can heave the pool out of the ground or cause the walls to collapse inward. Pools should be properly winterized and covered, but never left entirely empty.
Yes. While we specialize extensively in concrete and gunite structures, we also repair cracks, blisters, and gel coat damage on fiberglass pools. Fiberglass repairs require a different technique, involving specialized fiberglass matting, sanding, and the precise application of marine-grade gel coats to restore the watertight barrier and smooth finish. Our team adapts the diagnostic and repair process to match the exact materials of your aquatic facility.
Pools are heavy structures resting on soil. If the soil beneath or around the pool shifts, settles unevenly, or experiences extreme hydrostatic pressure from high groundwater levels, the concrete shell is forced to bend. Since concrete is rigid, this bending stress inevitably leads to a structural snap or crack. Ensuring proper yard drainage and addressing leaks immediately prevents the surrounding soil from washing away and exacerbating these ground shifts.
Cracks often develop at the throat of the skimmer or around plastic return jets because the plastic expands and contracts at a different rate than the surrounding concrete. We can carefully chip away the damaged material immediately surrounding the fixture, apply a specialized bonding agent, and reseal the area with hydraulic cement and pool putty to restore a watertight fit without requiring massive demolition to the rest of the pool wall.
If the repair is performed underwater using marine epoxies, you can typically swim the very next day. If the pool required draining for structural stapling, plastering, and epoxy injection, you must wait for the new materials to properly cure. We usually recommend waiting 48 to 72 hours before refilling the pool and balancing the chemicals, after which swimming can safely resume. We provide specific curing instructions based on the products used.
If your pool only has one or two localized cracks and the rest of the plaster is in excellent, smooth condition, a localized patch repair is the most practical and cost-effective route. However, if the entire pool surface is chalky, deeply etched, covered in spider cracks, or failing chemically due to old age, a complete resurfacing is often a better long-term investment. We assess the overall shell condition to provide an honest recommendation.
Yes. West Key Builders stands confidently behind our craftsmanship. We provide a workmanship guarantee on our structural pool crack repair services in London Ontario. The exact terms depend on the scope of the intervention and the existing condition of the pool shell, but we ensure that the specific area we have stabilized and sealed will perform reliably under normal operating conditions. We review these satisfaction guarantees prior to starting work.
Persistently wet, mushy, or unusually green patches of grass near your pool deck—even during dry weather—are strong indicators of an underground leak. This could be caused by a cracked underground plumbing line or a severe structural crack in the pool shell that is allowing water to seep into the surrounding soil. Prompt leak detection is necessary to prevent the escaping water from undermining the pool deck or the pool foundation itself.
When contacting us, it is helpful to provide the approximate age of the pool, the material it is constructed from (concrete, gunite, fiberglass, or vinyl), and a description of the problem. Tell us if you are losing water, how many inches per day, and if you have visibly located the crack. Providing clear photographs of the damage, the surrounding pool deck, and any wet areas in the yard helps us prepare properly for your site assessment.
