Slab Leak Reroutes in Boulder
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is a good fit when the slab is covered in tile or hardwood.

Electronic Acoustic Leak Detection in Boulder
Our team uses electronic listening devices to pinpoint the precise location of a slab leak.

Cold Water Slab Leak Detection in Boulder, CO
Cold water slab leaks do not create warm spots, so they are harder to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards.

Slab leak detection in Boulder typically costs $150 to $450. Repairs range from about $800 for a simple reroute to $3,000 or more for direct access under finished floors. We provide a written estimate after finding the leak.
Slab leaks can cause serious damage including foundation cracks, soil erosion beneath the slab, mold and mildew growth in wall cavities or under flooring, damage to flooring materials and increased humidity levels. Over time, it can lead to structural instability and major, costly repairs.
While you can look for the signs, accurately detecting a slab leak requires specialized equipment and expertise that most homeowners don't have. DIY attempts often lead to more damage or misdiagnosis, making professional detection a more cost-effective and reliable solution in the long run.
Many homeowner insurance policies cover the cost of water damage from a sudden or accidental slab leak, and sometimes the cost of accessing the leak for repair. However, coverage varies a lot, so it's essential to check your specific policy with your insurance provider.
Common signs of a slab leak in Colorado homes include unexplained increases in water bills, warm spots on your floor, the sound of running water when no fixtures are in use, damp or mildewy smells and visible cracks in your foundation or walls. Pooling water outside your home near the foundation can also be a strong indicator.
Warm spots on the floor, the sound of running water with fixtures off, a moving water meter and an unexplained jump in your water bill are common signs. Cracked tile, damp carpet and mildew odors also suggest a slab leak. Call us if you notice any of these.
Yes, a persistent slab leak can seriously damage your home's foundation.
