Leak Detection Company in Toronto

Aquamaster is a professional waterproofing and plumbing repair company with over 16 years of experience. Our Toronto leak detection services fit every need. Big or small leaks, we have a solution. Our team is constantly updating its knowledge and skills, combining years of hands-on experience with innovation and modern technology.

Advanced Water Leak Detection Services

We’re your one-stop shop leak detection specialists in Toronto. No matter where the source of the leak is, we have the resources to find it. Our full range of leak detection services includes:

Pipe Leak Detection

Pipe leak detection identifies leaks in water lines and drainage systems. These pipes are typically in the walls, ceiling, or beneath the foundation, which can make it more difficult to trace the source of the leak. We may use thermal imaging, smoke tests, and/or pressure testing.

Foundation Leak Detection

Foundation leaks can go unnoticed as there’s often no visible or clear source. Our team will determine if water tests, pressure tests, and/or moisture meters are best to find the exact location of the leak or moisture intrusion.

Fixture Leak Detection

While fixture leaks can be easier to spot than foundation or pipe leaks, there are a few tests we may need to perform in order to identify the source. If visual and auditory tests aren’t enough, our team will perform a pressure test.

Every leak is different, from the size and location to the cause. Fortunately, there isn’t a leak our team isn’t able to find and fix.

Peter completed the exterior waterproofing about six months ago and we’ve had several heavy rains since then. The basement has stayed 100% dry. His work clearly lasts. Truly impressed.

I can’t thank Aquamaster enough for their outstanding service. They fixed multiple cracks in my foundation, waterproofed the interior walls, and installed systems to keep groundwater away from the house. The workers were skilled, considerate, and left the entire area neat and tidy. Since the repairs, the basement is dry, safe, and ready to use again — no more worries about mold or structural damage. Superb workmanship and customer care.

1. Aquamaster did an incredible job waterproofing my basement. The crew arrived exactly when they said they would, took the time to walk me through each step of the process, and worked with impressive focus and efficiency. After the heavy rain last week, water that used to seep in every storm didn’t even make it to the threshold — the basement stayed completely dry for the first time in years. They left the work area spotless and followed up to make sure everything was performing as promised. I’m beyond happy with the results and would recommend Aquamaster to anyone who’s had ongoing moisture issues.

We had a leak in the corner of the basement after a storm, so we called Aquamaster. Alex and Julia came out the same week. They sealed the crack, dug outside to improve drainage, and checked the grading around the house. They even gave us maintenance tips so we wouldn’t face the same issue again. Amazing service and very polite team.

We contacted Aquamaster after discovering moisture behind our storage shelves. Daniel and Mark handled the repair. They were extremely professional — walked us through the entire waterproofing process, pointed out issues we never noticed, and explained how the foundation was shifting over time. They fixed the crack, sealed the base of the wall, added waterproof coating, and cleaned everything before leaving. The basement smells fresh now instead of damp.

We had a major basement flooding issue, and no one could figure it out—until we called Aquamaster Waterproofing. Sarah and David were thorough during the inspection and found that our sump pump had failed. They replaced it, installed a backup pump, and added better drainage around the foundation. The system works flawlessly now, and our basement has been dry ever since. Five-star service from a truly reliable company.

We recently moved into an older home and discovered water coming through the floor in the basement. Aquamaster’s team, led by Alex and David, came right away for an inspection. They installed a sump pump, sealed all visible cracks, and made sure our drainage system was working correctly. The workers were polite, neat, and extremely knowledgeable. It’s rare to find a company that combines great service with such high-quality workmanship. I’m beyond satisfied with the results.

How Much Does Leak Detection Cost in Toronto?

Our Toronto leak detection services vary in price, starting at $299+. We can provide an accurate estimate following a consultation. No obligation or fee is required for consultations.

Aquamaster's Leak Detection Process in Toronto

Aquamaster uses a variety of leak detection tools and techniques to find the exact source of the water and/or moisture intrusion. Our process involves the following:

Visual Inspection

Our expert leak detection technicians will visually inspect the basement, searching for signs of water damage. This can include mold and/or mildew on the walls, floor, or ceiling, wet walls, puddles of water, and water stains.

Water Testing

We may perform a water test, which involves spraying or pouring water into specific areas of the basement for observation. By running this test, we can pinpoint areas of water seepage, pooling, and/or leaks.

Moisture Measurement

We use moisture meters to determine the moisture content levels in different areas of the basement. Our team will use this to identify any elevated moisture levels in the basement walls, floor, and ceiling.

Thermal Imaging

Using advanced infrared cameras and thermal imaging technology, our team will search for temperature differences within the basement walls, floor, or ceiling. Cold spots can indicate water and/or moisture is present even though it isn’t visible.

Tracing Water Sources

The source of a leak can be traced back to foundation cracks, clogged drainage systems, or corroded pipes. Water intrusion can also come from foundation gaps, damaged window wells, or poor drainage around the exterior walls.

Pressure Testing

If a leak is difficult to detect, our team may perform a pressure test on the plumbing system. Our team will monitor for pressure drop, which can point to the presence of a leak.

Smoke Testing

We’ll release a non-toxic smoke into the plumbing system to check for cracks or breakages in the pipes. Our technicians will monitor the pipes, watching for smoke to emerge.

Final Report

Our technicians will document all findings from the inspection, testing, and imaging. The report outlines the leak’s source, affected areas, and recommended repair solutions. We’ll also provide advice to help prevent future water intrusion.

Professional Basement Leak Detection Services

Imagine you have a beautifully finished basement. All of a sudden you notice water stains & leaks on your basement wall or floor. Something needs to be done but it’s unclear where the leak is coming from. This is where basement leak detection specialists come in. Here are some scenarios that we often see with our clients:

  • Increased Water Bills – If you notice a sudden and unexplained increase in your water bills, it could be an indication of a hidden pipe water leak. Basement leak detection inside or outside the home can help identify the source of the leak and prevent further financial losses.
  • Damp or Wet Spots – If you find wet spots on your walls, floors, or ceilings, it could be a sign of a water leak. Our wet basement leak detection professionals can help pinpoint the exact location of the leak and recommend appropriate basement leak repairs.
  • Mould & Mildew Growth – The presence of mould or mildew in your home, particularly in areas prone to moisture like basements or bathrooms, could indicate a water leak. Leak detection can help identify the source of the moisture and prevent further potentially harmful mould growth.
  • Unpleasant Odours – Persistent musty or foul odours in your home may be a result of water leaks. We can help locate the source of the odour-causing moisture and address it effectively.
  • Water Stains & Discoloration – If you notice water stains or discoloration on walls, ceilings, or floors, it may be a sign of a hidden water leak. Our equipment will help check if the leak is coming from a pipe, wall crack or another source.
  • Dripping or Running Sounds – If the faucets are off but you hear dripping or running water sounds, it’s a good idea to talk to our leak detection experts. Walls, pipes, and plumbing systems may need to be checked to prevent water damage.
  • Foundation Cracks or Shifting – Cracks & shifting foundations can create pathways for water to enter your home. Professional opinion is needed to determine the extent of the damage and appropriate repair.

In any of these scenarios, it is advisable to contact a professional water leak detection service to accurately identify the source of the problem and provide appropriate solutions to prevent further damage and potential water-related issues in your home. Get one of our experts on the phone to discuss your leak & how to approach leak repair.

Common Sources of Basement Water Leaks

  • Concrete Slab Leaks: When under pressure, groundwater can seep through porous or cracked concrete slabs and into your basement.
  • Water Seepage: Factors such as inadequate drainage can cause groundwater to pool under the basement floor and rise through the concrete.
  • Over Top of Wall Leaking: Leaks that originate from the top of basement walls can be caused by poor grading as well as damaged or blocked gutters.
  • Window Well Leaks: Window wells can fill with water during heavy rainfall, leading to leaks in the basement.
  • Basement Cracks: Cracks in the basement walls, ceiling, or floor leave the space vulnerable to leaks during heavy rain, freeze-thaw cycles, and when the snow melts.
  • Mortar Joints: Mortar joints can deteriorate over time or become damaged from hydrostatic pressure. This can leave gaps between brick, block, or stone foundations, causing leaks.
  • Leaking Sump Pump & Overflows: Water can back up and leak into the basement if the sump pump breaks, clogs, or overflows from heavy rainfall.
  • Pipe Penetrations:  Damaged seals or cracks around pipes in the foundation can let rainwater and groundwater leak into the basement.
  • Leaking Pipes: When water and drainage pipes burst, crack, corrode, or clog, the previously contained water can start to leak into the basement.
  • Sewage Backup: Sewer lines that are blocked or overflowing can cause sewage to back up into the basement.
  • Clogged Drains: Without regular maintenance, basement floor and perimeter drains can fill with debris. This can cause flooding in the basement.
  • Cove Joints: When groundwater builds up around the foundation, it increases hydrostatic pressure. Cove joints can become strained and more vulnerable to water infiltration.
  • Leaky Tie Rods: Water can seep into the basement through tie rod leaks, which are small holes created by steel rods used during construction.
