Slab Leak Detection in Flagstaff
We start by shutting off fixtures and watching the meter to confirm a leak. Then we isolate the hot and cold lines to determine which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.

Hot Water Slab Leak Repair in Flagstaff, AZ
Hot water lines leak under slabs more often than cold lines because heat expands and contracts the pipe against concrete and gravel. Hard water scale and constant recirculation can wear the pipe wall faster. We repair the leak or reroute the hot line, and we can adjust recirculation pumps to reduce wear. Warm floors and higher gas or electric bills are common signs.
Cold Water Slab Leak Repair in Flagstaff
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, locate the leak and repair or reroute it. Fixing cold leaks quickly helps protect your foundation.
Spot Repair Through the Slab in Flagstaff, AZ
When the leak is isolated and the rest of the pipe is in good shape, a spot repair through the slab is a practical option. We cut a small opening, excavate to the pipe and replace the damaged section. The trench is compacted and the concrete is patched. Flooring is then restored by your preferred contractor.
Slab Leak Reroute in Flagstaff
Rerouting is often the best long-term choice, especially with older copper lines. We abandon the leaking line under the slab and run a new PEX line through the attic and walls. Openings are small and placed where patching is easiest. Reroutes eliminate future leaks in that section of pipe.
Emergency Slab Leak Repair in Flagstaff, AZ
A major slab leak can push water up through flooring or into walls quickly. We help you shut off the water and send a technician to isolate the leaking line. Often we can restore water to the rest of the house while we plan the repair. Quick action limits flooring damage and soil saturation.
Commercial Slab Leak Repair in Flagstaff
Retail stores, offices and restaurants built on slabs can also develop slab leaks. These leaks can affect tenants and operations if not repaired quickly. We locate and repair commercial slab leaks with minimal disruption, often working after hours. We provide documentation for property managers and insurers.

Slab Leak Repair Cost Comparison in Flagstaff, AZ
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost a bit more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you clear prices for each option.
