What are Water Leaks & How to Find Them?

What is Water Leak Detection?

Basement leak detection refers to the process of identifying and locating water leaks or sources of moisture in a basement or below-ground level of a building. Basements are prone to water seepage due to factors such as inadequate waterproofing, foundation cracks, plumbing leaks, or poor drainage systems.


Our team of leak detection specialists can help you identify water leaks no matter where they come from. From underground leak detection to wall and floor leak detection we will pinpoint the exact locations & will help repair the water leak. Talk to a specialist today!


Scenarios Where Leak Detection is Needed

Why do you Need Professional Leak Detection Services?

Imagine you have a beautiful finished basement. All of a sudden you notice wet 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. Our team has special equipment and training to detect basement water leaks and repair them. Here is a couple of 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. Water leak detection inside or outside can help identify the source of the leak and prevent further financial losses.

  • Damp or wet spots - if you find damp or wet spots on your walls, floors, or ceilings, it could be a sign of a water leak. Water leak detection professionals can help pinpoint the exact location of the leak and recommend appropriate repairs.

  • Mold & mildew growth - the presence of mold or mildew in your home, particularly in areas prone to moisture such as basements or bathrooms, could indicate a water leak. Leak detection can help identify the source of the moisture and prevent further mold growth, which can be harmful to your health.

  • Unpleasant odors - persistent musty or foul odors in your home may be a result of water leaks. Water leak detection can help locate the source of the odor-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 – when the faucets are off, but you hear dripping or running water sounds, it’s a good idea to talk to leak detection experts. Walls, pipes, and plumbing system may need a check 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.

Basement Leak Detection Process

Basement Leak Detection - Methods & How it Works


There is a number of methods of finding the leak in your walls, floors or even underground.

Our approach involves a systematic process to locate water leaks or sources of moisture in a basement. Here's how basement leak detection typically works:


  • Visual Inspection - a professional will visually inspect the basement, looking for visible signs of water damage, such as damp spots, mold growth, efflorescence (white mineral deposits), or discoloration on walls, floors, or ceilings.

  • Water Testing - water may be sprayed, poured, or introduced into specific areas or sections of the basement to observe how it behaves. This helps identify if water seeps through, accumulates, or follows a specific path, indicating the presence of leaks.

  • Moisture Measurement - moisture meters are used to measure the moisture content in different materials, including walls, floors, and other surfaces. Elevated moisture levels can indicate the presence of leaks or excessive dampness.

  • Thermal Imaging - infrared cameras or thermal imaging devices can be employed to detect temperature differences in the basement. Cold spots may indicate the presence of water or moisture, potentially revealing hidden leaks.

  • Tracing Water Sources - professionals will analyze the basement and surrounding areas to trace the possible sources of water intrusion. They may inspect plumbing systems, check for cracks in the foundation, evaluate the drainage system, or look for other potential entry points.

  • Pressure Testing - in some cases, pressure testing is conducted on the plumbing system to identify hidden leaks that are not easily visible. By pressurizing the system, professionals can monitor pressure drops that suggest the presence of leaks.

  • Smoke Testing - smoke testing involves introducing non-toxic smoke into the plumbing system to identify leaks or breaks. The smoke travels through the pipes and reveals the location of leaks as it emerges from cracks or openings.


Once your basement leak detection company finds the source(s) of the leaks are identified, appropriate repair and mitigation measures can be implemented. These may include sealing cracks, waterproofing the basement, installing sump pumps or drainage systems, fixing plumbing leaks, or taking other necessary steps to prevent water intrusion and damage.


It's important to note that basement leak repair & detection can be a complex process, and it's often recommended to seek professional assistance from experienced technicians who specialize in leak detection and repair. They have the expertise and tools to accurately identify and address the water leak issues in your basement.

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
