If your Firestone meter registers use with nothing running, or a patch of floor turns warm or damp, a supply line beneath the slab may be leaking. Firestone's homes are mostly newer, so the culprit is often a fitting rather than worn pipe, and the plumbing in and under the house is the owner's to fix. Call the number on this page to be connected with a local plumber in Firestone.

Firestone is a fast-growing Carbon Valley town along I-25, made up mostly of newer family subdivisions. Most homes get water from the Town of Firestone, which buys treated water from Central Weld County Water District and the St. Vrain Water Authority; homes in Barefoot Lakes are served by Little Thompson Water District instead. Central Weld reports soft water, about 33 mg/L, and the town's service line inventory is known non-lead. Sewer is handled by St. Vrain Sanitation District. Because so much of Firestone was built recently, the pipe under a slab here is often plastic. It will not corrode, but a crimp or push fitting can let go, and a line kinked or nicked during construction can start leaking years later. Many homes have basements, and a basement floor is a slab with lines under or within it.
What to do right away
- Run a meter test. Turn everything off, including the sprinklers, take a reading, wait an hour, and read again.
- Check toilets and hose bibs. These are the most common false alarms.
- Isolate the water heater. Close the cold inlet. If the meter stops, focus on hot lines.
- Look for heat or moisture. Walk the floors barefoot and check basement carpet edges.
- Protect your floors. If water appears, shut the main and move belongings.
- Have it located. A plumber should pressure test and listen before opening concrete.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Warm floor in one stripe | Hot line or fitting leaking below |
| Meter creeping, floors normal | Cold-side leak, or the yard line to the house |
| Basement carpet damp at the edge | Water rising through the slab |
| One fixture with poor flow | Leak on that branch line |
| Water heater cycling often | Hot water escaping somewhere |
Cost factors
- Time spent isolating and pinpointing the leak
- Whether a spot repair or a reroute fits the layout
- Flooring and finished basement surfaces to restore
- Drying and drywall repair
- Permit requirements through the Town of Firestone Building Division
In a newer house, one failed fitting in otherwise sound pipe often makes a spot repair reasonable; a plumber can confirm once the leak is exposed. If more than one fitting has failed in the same run, a reroute is usually the safer long-term choice.
