What is Basement Leak Detection?
Basement leak detection is the process of identifying and locating water leaks or sources of moisture in a basement or the 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.

Aquamaster’s Professional Basement Leak Detection Services
- 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.
How Our Basement Leak Detection Works
- Visual Inspection – A basement leak detection professional will visually inspect the basement, looking for visible signs of water damage, such as damp spots, mould 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 – Basement leak detection 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 detect 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 expert finds the source(s) of the leaks, 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.
