Slab Leak Repair in Boulder, CO

Signs that point under the floor

• Water use registers on the meter while every fixture is closed
• Warm tile in a kitchen or bath, often in a line
• Persistent dampness at the base of a wall or under a rug
• Higher bills from the city without a change in habits
• The sound of water moving when the house is quiet

Any one of these can have a simple explanation, such as a toilet flapper that seeps. When two or more show up together, it is worth a proper pressure test.

Boulder conditions that matter

Boulder operates its own water system, fed by Barker Reservoir, North Boulder Creek, Carter Lake and Boulder Reservoir and treated at the Betasso and 63rd Street plants. The city runs a corrosion control program to limit lead from home plumbing, and its service line inventory found no lead service lines. None of that suggests the water is attacking pipe under slabs; buried copper usually fails from age, abrasion against stone, or a stressed joint.

Permits are a real consideration in Boulder. Planning and Development Services treats minor work such as repairing a leak as exempt, but replacing concealed supply piping counts as new work and needs a permit. In practice, a small spot repair may not need one, while a reroute through walls or a new run under the floor will. The plumber will know which applies once the leak is found.

Price factors

• Diagnostics. Splitting hot from cold, pressure testing, then acoustic or thermal locating.
• Method. A targeted opening in the slab, or abandoning the run and installing new pipe above.
• Surfaces. Stone or tile floors and finished basements take more work to restore.
• Drying out. Wet drywall, insulation or cabinetry adds to the job.
• Permit. Needed when concealed piping is replaced.
