A Henderson slab leak is a water supply line leaking under a concrete floor, often in a basement or a slab-level room. Henderson is a patchwork of unincorporated land and areas annexed by nearby cities, so water providers vary by address, but the plumbing in and under your house is yours to repair. Call the number on this page to be connected with a local plumber in Henderson.

What points to a slab leak
- The water meter moves while every fixture and the irrigation are off
- A warm band on tile or a basement floor
- Damp carpet or baseboards with no plumbing fixture nearby
- A jump in the water bill without a change in routine
- A water heater that runs more than usual
A running toilet or dripping outdoor faucet can mimic these, so check those first.
Henderson's patchwork
Henderson is a small unincorporated Adams County community with a post office dating to 1894 and a few older buildings along Brighton Road north of 120th Avenue. Much of the surrounding area has been annexed by Commerce City, Brighton and Thornton. That matters for two practical questions. First, the water provider depends on the exact address: annexed parcels may be served by one of those cities' providers, while other homes are on different systems. We could not confirm a single provider for Henderson, so check your water bill, or ask Adams County if you are unsure. Second, the permit office changes too: unincorporated parcels go through Adams County, while annexed parcels fall under Commerce City, Brighton or Thornton.
Homes in the area range in age, so the pipe under a slab could be older copper, which can wear where it rubs against gravel, or newer plastic, which tends to fail at fittings. Either way, a leak inside or under the house is a private plumbing repair.
Cost considerations
- Locating. Isolating hot and cold, pressure testing each side, then acoustic or thermal tracing.
- Repair method. A targeted opening at the leak, or a reroute through walls and ceilings.
- Surfaces. Tile, wood and finished basements cost more to restore.
- Damage. Wet drywall or carpet pad may need drying.
- Permit. Adams County requires a building permit for plumbing modifications in unincorporated areas; annexed parcels follow their city's rules.
When you call
