What Is Water Leak Repair?
Water leak repair is the professional process of locating and fixing hidden water leaks in pipes, fixtures, and foundations. Water Pro combines advanced detection technology with expert repair services to identify where water is leaking from your plumbing system, then performs targeted repairs to stop the leak and restore system reliability. Most residential leaks are hidden inside walls, beneath concrete slabs, or within aging pipe networks where they cause invisible water damage for months or years.
Professional leak detection saves thousands by pinpointing exact leak location, eliminating guesswork and exploratory damage. We use acoustic listening equipment, thermal imaging cameras, and pressure testing to find leaks non-destructively, then repair with minimal structural disruption. A single undetected leak wastes 5,000-15,000 gallons monthly while causing mold growth, wood rot, and foundation deterioration. Early detection and professional repair prevent catastrophic water damage. Call (647) 554-4356 when you notice signs of hidden leaks.
Common Water Leak Locations in Toronto Homes
Hidden leaks develop in specific locations within Toronto's aging water infrastructure. Professional detection finds leaks regardless of location.
In-Wall Pinhole Leaks
Pinhole leaks develop from internal pipe corrosion, creating tiny holes that spray water directly into wall cavities. These leaks go undetected for months because the water dampness stays hidden inside walls. Visible signs appear only after extensive mold growth or water stains surface. Toronto homes with 40-year-old copper or galvanized pipes frequently develop pinhole leaks from hard water mineral deposits and corrosion. Acoustic detection identifies pinhole leaks by sound of water escaping under pressure.
Professional patching stops pinhole leaks immediately with minimal wall disruption. We patch directly at leak point rather than replacing entire pipe sections. Cost: $200-$600 depending on accessibility and pipe type. Prevention: Consider pipe relining or strategic section replacement for homes showing multiple pinhole leak risk factors.
Slab Leaks Under Foundation
Water main or supply lines running under concrete foundations develop leaks from freeze-thaw stress, soil shifting, and corrosion. Slab leaks are nearly impossible to detect without professional technology because leaking water disappears into soil beneath the foundation. Toronto homes built on expansive clay soil experience frequent slab leaks from foundation movement. Thermal imaging reveals temperature anomalies from water escaping under slabs.
Slab leak repair typically requires excavation to access damaged section. Costs range $600-$2,500+ depending on leak depth and soil conditions. Early detection prevents foundation damage and expensive excavation. Professional assessment determines if repair or replacement is most cost-effective solution for your situation.
Joint and Connection Failures
Pipe joints and solder connections deteriorate over decades, developing slow leaks that escalate into active failures. Old solder joints from 1960s-1980s construction fail as solder weakens and cracks develop. Connection leaks at tees and elbows drip continuously into basements or crawl spaces. These leaks are visible once water reaches basement, but the source location in walls above remains hidden. Joint failures account for 40% of residential water leaks in Greater Toronto Area.
Professional repair involves joint replacement using modern mechanical connections or press-fit technology. Repair costs $300-$800 per joint depending on accessibility and pipe type. Multiple joint failures suggest whole-pipe relining may be more cost-effective than repeated repairs.
Water Main Leaks Outside Home
Toronto's underground water mains frequently leak where they enter homes or connect to municipal supply lines. Ground water pooling in yards, unusually lush grass patches, or wet basement corners indicate external water main leaks. These leaks waste massive water volumes while causing foundation saturation and mold risk. Professional assessment determines if leak is on city side or your property responsibility.
Water main repair typically ranges $600-$2,500 depending on break location and soil conditions. City may cover repairs for municipal line leaks. Professional detection and documentation supports any insurance or city responsibility claims. Early detection prevents foundation damage and prevents escalating repair costs.
Fixture and Supply Line Leaks
Leaks develop at toilets, sink supply lines, washing machine connections, and fixture shutoff valves. These visible leaks are easier to detect but often indicate underlying water quality issues affecting other pipes. Slow fixture leaks waste thousands of gallons monthly while appearing minor. Water stains below fixtures, mold growth around supply lines, or soft flooring indicate fixture leaks. Professional assessment determines if leak is fixture-specific or system-wide corrosion problem.
Fixture leak repair costs $150-$600 depending on component replacement or line repair needed. Replacing old supply lines with modern PEX prevents recurring fixture failures. Preventive upgrades recommended for homes with multiple fixture leaks indicating aging water delivery system.
Ceiling and Attic Leaks
Second-floor bathroom leaks, roof penetration leaks from vent stacks, and overhead supply lines leak directly down through ceilings and into walls below. These leaks damage insulation, drywall, and structural framing while creating mold risk throughout home. Water stains on ceilings indicate active overhead leaks. Professional detection identifies leak source (interior plumbing versus roof/envelope leak) determining repair approach and contractor specialty.
Overhead leak repair costs $300-$1,200+ depending on source identification and structural damage. Professional assessment prevents unnecessary roof repair if leak source is interior plumbing. Early detection and repair prevents ceiling collapse and extensive water damage restoration costs.
Signs You Have a Hidden Water Leak
These warning signs indicate hidden water leaks active in your home. Call (647) 554-4356 immediately for professional leak detection.
Unusually High Water Bills
Sudden increase in water bill without increased usage indicates hidden leak. Even small leaks waste 10,000-15,000 gallons monthly. Compare current bill to average of past 12 months. If usage jumped 30%+ without explanation, professional detection is essential to locate leak and stop water waste.
Musty Odors and Mold Smell
Strong musty smells in basements, crawl spaces, or upstairs bedrooms indicate water damage and mold growth from hidden leaks. Mold thrives in wet environments created by continuous water seepage into walls and insulation. Musty odor often appears weeks before visible mold, providing early warning of active leak.
Water Stains and Discoloration
Yellow, brown, or rust-colored stains on ceilings, walls, or baseboards indicate active water damage from overhead or adjacent leaks. Stains typically appear after months of water seeping into drywall. Multiple stains in same area suggest single leak source. Professional leak detection pinpoints source before stains become widespread.
Unusually Lush Grass Patches
Bright green, overgrown grass patches in yard while surrounding lawn appears normal indicate water main leak underground. Escaping water from buried lines saturates soil, promoting grass growth. These patches often appear in winter when water leak is most noticeable against brown dormant lawn.
Damp Spots on Floors or Walls
Soft or spongy flooring, damp patches on baseboards, or wet walls indicate water saturation from nearby leaks. These areas feel cool and damp to touch even though no active water appears. Soft flooring suggests water damage to subfloor requiring urgent detection and repair before structural damage spreads.
Running Water Sounds in Walls
Hearing water flowing inside walls when no faucets are open indicates active leak under pressure spraying water into wall cavity. These sounds are most noticeable at night when home is quiet. Professional acoustic detection isolates exact location of spraying water for precise repair placement.
Visible Mold on Surfaces
Black or green mold spots on walls, ceilings, or corners indicate active moisture from hidden leaks creating mold growth conditions. Visible mold suggests leak has been active for weeks or months. Professional remediation and leak repair prevent mold from spreading throughout home and causing health issues.
Water Meter Keeps Running
Check water meter when all faucets are off and no toilets are running. If meter dial continues spinning, active leak is in water delivery system. Meter movement without water use confirms leak somewhere between city line and home fixtures. Professional assessment determines if leak is exterior or interior plumbing system.
Pest and Insect Activity
Increased pest activity (termites, carpenter ants, roaches) in basement or crawl spaces indicates moisture-rich environment created by hidden leaks. Pests thrive in wet, moldy conditions. Addressing underlying leak prevents pest problems and structural damage from pest activity and water damage combined.

Advanced Water Leak Detection Methods
Water Pro uses multiple detection technologies to pinpoint hidden leaks without destructive exploration or wall removal.
Acoustic Detection
Sensitive electronic listening devices detect water escaping under pressure from pipes. Pinhole leaks and joint failures produce characteristic hissing or spraying sounds. Technicians place sensors on pipes and walls, listening for leak noise signatures. Acoustic detection precisely locates leaks without disturbing walls or foundation. Cost: $150-$300 depending on complexity.
Thermal Imaging
Infrared thermal cameras visualize temperature differences from water escaping into walls and under floors. Leaking water creates cooler spots visible on thermal images. Thermal imaging finds slab leaks under concrete, leaks deep in walls, and water main breaks underground. Professional interpretation identifies whether thermal anomaly is leak or normal building moisture. Cost: $300-$500 for thermal assessment.
Dye Testing
Food-grade dye injected into water supply visibly shows water path when leak occurs. Technicians trace where dye-colored water appears, directly indicating leak location. Dye testing pinpoints pinhole leak locations precisely. Safe for drinking water system and visible on walls, floors, or soil. Cost: $200-$400 depending on system complexity and leak location.
Pressure Testing
Specialized equipment pressurizes water system while monitoring pressure drop rate. Rapid pressure loss indicates active leak size and location. Technicians isolate sections of pipe using shutoff valves, then test each section separately. Pressure testing determines if leak is in delivery lines, fixtures, or specific building section. Cost: $200-$350 for diagnostic testing.
Water Quality Testing
Analysis of water samples identifies corrosion byproducts indicating pipe deterioration and imminent failure. High copper, zinc, or iron levels confirm active corrosion creating pinhole leaks. Water quality testing predicts future leak risk and recommends preventive upgrades. Results guide pipe replacement decisions. Cost: $150-$250 for comprehensive water analysis.
Video Pipe Inspection
High-definition camera on flexible cable travels through pipes, visualizing interior condition and identifying corrosion, cracks, or breaks. Video inspection shows exact problem location and severity. Best for sewer and drain lines but available for supply lines in some circumstances. Professional interpretation provides clear diagnosis. Cost: $400-$800 depending on line length and accessibility.
Multi-Method Detection Approach
Water Pro combines multiple detection methods to achieve highest accuracy. A single acoustic test might miss water main leaks, while thermal imaging alone could miss small pinhole leaks. Professional assessment uses appropriate combination of technologies:
- • High water bill: Pressure testing + acoustic detection to find leak rate and location
- • Wet basement: Thermal imaging + acoustic detection for slab or foundation leaks
- • Visible stains: Dye testing + acoustic detection to trace water path from source
- • Mold and odors: Thermal imaging + visual inspection to locate moisture source
- • Corrosion suspected: Water quality testing + video inspection for comprehensive system assessment
Water Leak Repair Methods Based on Type & Location
Repair method depends on leak type, location, and pipe material. Professional assessment recommends most cost-effective permanent solution.
Pinhole Leak Patching
Cost: $200-$600
For small pinhole leaks, epoxy patches or mechanical patch kits stop water flow immediately with minimal disruption. We access pipe section, clean and dry surface, apply epoxy patch rated for water pressure service. Patching requires 24-hour cure time before full water pressure. Professional patching prevents patch failure and pressure testing ensures seal integrity. Best for isolated pinhole leaks, not recommended for multiple pinholes indicating widespread corrosion.
Pros: Fast, minimal structural damage, preserves wall integrity, low cost
Cons: Short-term solution if corrosion is widespread, may fail if multiple leaks exist
Pipe Joint Replacement
Cost: $300-$800 per joint
Failed solder joints are removed and replaced with modern mechanical press-fit connections or new soldered joints with lead-free solder. We shut off water, cut out failed joint section, and install new connection tested for leaks. Modern mechanical press-fit connections eliminate soldering and provide superior reliability. Professional joint replacement prevents reoccurrence of same leak location. Works for both supply and drain line joints.
Pros: Permanent solution, improved joint design, guaranteed results with warranty
Cons: Requires water shutoff, higher cost for multiple joints, wall access needed if joints in walls
Pipe Section Replacement
Cost: $600-$1,500+ per section
For severe corrosion or burst pipes, we cut out damaged section and replace with modern PEX or copper pipe. New material is pressure tested and pressure rated for long-term durability. Replacement prevents future leaks from same pipe section and restores full water delivery capability. We connect new pipe using modern mechanical fittings for superior reliability. Best permanent solution for pipes showing severe corrosion or multiple pinhole leaks in short section.
Pros: Permanent solution, prevents future leaks in same section, improved pipe material, 90-day warranty
Cons: Higher cost, wall or foundation access may be needed
Pipe Relining
Cost: $1,200-$2,500+
Trenchless relining technology coats existing pipe interior with epoxy coating, sealing all leaks and pinhole damage simultaneously. Epoxy coating prevents future corrosion and extends pipe life 50+ years without replacement. No wall removal, no excavation, pipe remains in place. Relining works for severely corroded pipes showing multiple leaks. Professional relining restores full water pressure and durability without property disruption.
Pros: Fixes multiple leaks at once, trenchless method, no wall removal, extends pipe life 50+ years
Cons: Higher upfront cost, 24-hour cure time, requires specialized equipment

Water Leak Repair FAQs
Common questions about water leak detection and repair in Toronto. Don't see your question? Call (647) 554-4356 to speak with our leak specialists.
How do I know if I have a hidden water leak?
Common signs include unusually high water bills, damp spots on walls or floors, visible mold growth, musty odors in basements, or hearing water sounds inside walls. You might notice soft or spongy flooring, wet patches in yards, or water stains spreading on ceilings. Check your water meter - if it runs when no water is in use, a leak is active. Professional detection can confirm hidden leak even if signs are subtle. Call (647) 554-4356 for assessment.
How much does leak detection cost?
Professional leak detection typically costs $150-$350 depending on detection method complexity and leak location difficulty. Basic acoustic detection costs $150-$250. Advanced thermal imaging costs $300-$500. Dye testing costs $200-$400. We provide upfront quotes before beginning work. Detection fee is often credited toward repair cost if you choose our repair services, making actual leak detection cost much lower.
Can you find leaks in walls or under floors?
Yes! Water Pro specializes in finding hidden leaks inside walls, under concrete slabs, and beneath floors using advanced detection technology. Acoustic detection hears water escaping from pressurized pipes. Thermal imaging reveals temperature changes from escaping water. Dye testing traces water flow path. Professional detection finds leaks without demolishing walls or cutting up flooring. Once located, we recommend repair method minimizing structural disruption.
What causes water leaks in Toronto homes?
Toronto's aging infrastructure and freeze-thaw climate cause multiple leak types. Freeze-thaw cycles crack pipes 40+ years old. Hard water mineral deposits corrode copper pipes from interior, creating pinhole leaks. Soil shifting on clay foundations pinches slab leaks. High water pressure stresses aged pipes until joint failures develop. Poor installation from decades-old construction creates stress points. Professional assessment identifies which causes affect your specific home and recommends preventive upgrades.
How long does leak repair take?
Once leak location is confirmed, repair time varies by type. Pinhole leak patching takes 30-60 minutes plus epoxy curing. Joint replacement takes 1-2 hours. Pipe section replacement takes 2-4 hours depending on accessibility. Complex leaks affecting main water line take 4-6 hours. We provide realistic time estimates during detection consultation. Many repairs complete same-day, restoring full water supply immediately. We schedule repairs at your convenience with minimal home disruption.
Will leak repair damage my walls or floors?
Professional leak repair minimizes structural damage. For accessible basement or crawl space leaks, repair requires zero drywall removal. For wall leaks, advanced detection pinpoints exact location, we create minimal access hole directly at leak point avoiding unnecessary demolition. After repair, we patch holes with matching materials. For extensive water damage, restoration contractors handle structural repairs separately. Professional detection eliminates exploratory damage from guesswork.
Is water leak repair covered by insurance?
Most homeowner insurance policies cover sudden and accidental water leaks under water damage coverage. Gradual leaks from aging pipes may have coverage limitations. We provide detailed documentation and damage assessment for your insurance claim. Our licensed technicians photograph damage, prepare repair estimates, and coordinate with adjusters to maximize claim approval. Check your policy details and contact your agent before beginning repairs to understand coverage.
Can small leaks become big problems?
Small leaks escalate rapidly into catastrophic problems. A single dripping joint wastes 15-20 gallons daily, accumulating 5,000+ gallons monthly. Mold thrives in wet environments from continuous leaking. Pinhole leaks expand as corrosion spreads. Hidden foundation leaks undermine structural integrity. Early detection and professional repair prevents thousands in restoration costs. Small leaks discovered by sudden water bill spike should be addressed immediately before extensive damage develops.
How can I prevent water leaks?
Regular preventive maintenance reduces leak risk significantly. Annual professional pipe inspections identify corroded sections before leaks develop. Install smart leak detection sensors alerting you to unexpected water usage. Maintain water pressure below 60 PSI to reduce stress on aging pipes. Have foundation drainage inspected annually. For homes 40+ years old, replace aging galvanized pipes with modern PEX or copper. Weatherproof exterior walls and foundation cracks. Our technicians provide prevention consultations identifying your home's specific leak risk factors.
