Slab Leak Detection in Williston
Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use dedicated acoustic equipment and thermal cameras to pinpoint leaks under your home's foundation without destructive digging. Early detection of a slab leak prevents serious structural damage and mold issues, saving you real repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.
Sewer Line Leak Detection in Williston, ND
Sewer line leaks can cause unpleasant odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines. This method allows for precise location of the leak without guesswork, leading to more efficient and targeted repairs. We repair sewer leaks in all types of piping materials common in Williston homes, from PVC to cast iron.
Water Leak Detection in Walls & Ceilings in Williston, ND
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to serious drywall damage, wood rot and mold. We use non-invasive methods like moisture meters, thermal cameras and borescopes to precisely pinpoint the source of these leaks. This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's interior.
Pool and Spa Leak Detection in Williston
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.

Leak Detection Cost Comparison in Williston, ND
Professional leak detection typically costs $150 to $450 for a standard home, depending on the system size and how many areas need testing. Pool leak detection usually runs $250 to $500. Repair costs vary a lot, from $150 for a fixture fix to several thousand dollars for a slab reroute. Accurate detection keeps the repair cost as low as it can be.

The cost of leak detection in Williston can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or those requiring special equipment may be at the higher end. We provide a detailed estimate after our initial assessment.
Yes. Acoustic and thermal tools let us locate most leaks without opening anything. We only open a small area once the leak is confirmed.
If you suspect a gas leak, immediately evacuate everyone from the property, do not use any electrical devices, and call your gas utility company and HPN Plumbing from a safe location. Gas leaks are extremely dangerous and require immediate professional attention.
Yes, the hard water common in many parts of the country can contribute to scale buildup inside pipes, which over time can corrode pipe materials and lead to pinhole leaks or joint failures. Regular plumbing maintenance can help limit these risks.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material degradation. Copper pipes can develop pinhole leaks over time, while PVC and PEX are generally more reliable but can still leak at fittings or due to installation errors.
While you can check for obvious leaks like dripping faucets, hidden leaks require professional tools and expertise. DIY attempts can often misdiagnose the problem or cause further damage, especially with slab or gas leaks.
Yes. Repairs we complete after detection carry a written workmanship warranty. Replacement parts include manufacturer warranties.
We use a range of advanced tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for precise and non-invasive leak identification.
