A slab leak is a pressurized water line leaking beneath your concrete foundation — and it is one of the most destructive leaks a home can hide. Hot-line breaks announce themselves as warm spots on the floor; cold-line breaks show as damp patches, cracks in tile, or the sound of running water with nothing on. Our slab leak service combines thermal imaging surveys that see the heat bloom through flooring with acoustic ground microphones that hear the break through concrete, pinpointing the leak within inches. That precision means repair opens one small area — not the whole floor. Round-the-clock answering, 30–45 minute arrival, anywhere in Broomfield.
Open now — calls answered 24/7, every day of the year.
Finding a leak under concrete takes instruments that see and hear through it. These are the methods inside every slab leak visit.
Acoustic and thermal readings converge on the break’s exact position under the slab. We mark the spot so your repair contractor opens the smallest possible area of concrete.
Infrared cameras scan tile, wood, and carpet for the warm bloom of a hot-water line break. A hot spot that was not there last month is the classic slab-leak signature.
Pressure tests on hot and cold lines separately prove which system is losing water. Isolating the failing line first keeps the search — and the repair — focused.
We map the buried pipe runs beneath the foundation, so the leak’s position is understood in the context of the whole system — essential when rerouting is smarter than breaking concrete.
The pinpoint gets marked with paint or tape, photographed, and written up with readings — everything needed for a spot repair, a reroute estimate, or an insurance claim.

Each of these slab leak symptoms has a specific cause our instruments can confirm. If you recognize your slab leak symptom below, the next step is a diagnostic visit — not guesswork.
A warm area on tile or wood that was not warm before is the signature of a hot-water slab leak. Thermal imaging confirms it in minutes — the heat bloom is unmistakable.
Moisture wicking up through the slab dampens flooring from below. If one area stays damp while the rest is dry, water is rising through the concrete.
Hearing water move beneath the floor with every fixture off means a pressurized line is discharging under the slab. Acoustic microphones trace the sound to the break.
A rising bill paired with new floor symptoms is the slab-leak double signature: the meter proves water loss while the floor shows where it surfaces.
Hairline cracks widening across tile or slab, or grout lines darkening in one zone, can mean water undermining the foundation from below.
Continuous meter flow with no visible leak anywhere above grade points downward. When walls and fixtures test clean, the slab is the next place we look.
Slab work demands certainty before concrete is touched. Our sequence builds proof in layers — thermal, acoustic, pressure — before anything is marked.
We scan every accessible floor surface with the infrared camera, mapping heat anomalies room by room. Hot-line breaks reveal themselves as distinct warm blooms against the cooler slab.
Pressure tests on the hot and cold systems separately identify which side is losing water. This single test often cuts the search area in half before we listen for anything.
Ground microphones press to the slab surface along the suspect run. The leak’s hiss grows louder as we approach the break — we walk the sound gradient to the loudest point.
The pinpoint is marked on the floor, photographed with a tape measure for scale, and documented with thermal images and pressure readings — ready for your contractor’s spot repair or reroute decision.
Slab leaks punish guesswork more than any other leak type: every wrong guess is a jackhammered hole in your foundation. After 25 years of under-slab work in Broomfield, our pinpoints hold up — contractors open where we mark and find the break.
Thermal imaging shows the heat, acoustic equipment hears the break, and pressure testing proves the line — we require all three to agree before marking concrete. That discipline is why our slab pinpoints land within inches instead of feet. We also think beyond the hole: by tracing the under-slab line runs, we can advise whether a spot repair or a reroute makes more sense for an aging system, and our documentation supports insurance claims where slab damage is involved. Clean, quiet, and precise — the way foundation work should begin.
Real reviews from Broomfield customers, shown exactly as provided.
Slab leaks reward early catchers. These habits surface them while the repair is still small.
Your feet are surprisingly good thermal sensors. A regular barefoot walk across tile floors notices new warm patches long before eyes do.
Date-stamped photos of grout or tile cracks create a timeline. Cracks that widen over weeks suggest movement from water below.
Slab leaks often start near where lines rise from the slab. Dampness or warmth around the water heater’s base deserves a thermal check.
A climbing bill plus any new floor symptom — warmth, dampness, sound — is the double signature. Do not wait for visible damage.
Homes on slab foundations route water lines through or under concrete. Knowing yours are under-slab lines reframes every warm spot as a suspect.
Running-water sounds beneath the floor never resolve themselves. Every week of delay is more erosion under the foundation — call while the pinpoint is easy.
Water visibly spreading across the floor from beneath, a hot spot growing by the hour, or the sound of rushing water under the slab — these are slab emergencies, and waiting lets water undermine the foundation further. Our 24/7 line dispatches immediately with a 30–45 minute arrival; we isolate the failing line on arrival to stop the loss, then pinpoint the break so repair can begin through one small, precise opening. See our emergency slab leak service.
Broomfield’s slab-foundation homes — from the neighborhoods around Flatiron Crossing to the streets near the Broadlands — share the same vulnerability: pressurized lines buried in concrete. Our technicians have mapped slab leaks across the entire city for 25 years and reach emergency calls in 30–45 minutes. If you searched for slab leak help near you and found a warm spot on your own floor, call the local team that marks the break within inches before anyone lifts a jackhammer.
Most often, a warm patch on tile, wood, or carpet that was not warm before — the signature of a hot-water line break under the concrete. Cold-line breaks feel damp or cool instead, and sometimes you hear faint running water with everything off. Any new floor sensation that persists deserves a thermal scan.
Thermal cameras see the heat bloom of a hot-line break through flooring, and acoustic ground microphones hear the hiss of any pressurized break through the slab. Pressure tests on hot and cold lines separately prove which system is failing. We mark the spot only after multiple instruments agree.
With thermal, acoustic, and pressure evidence converging, we mark the break within inches — close enough that repair opens one small area of concrete. Contractors regularly open where we mark and find the leak waiting. Certainty before concrete is the whole point of the service.
It depends on the pipe’s age and condition, which our line tracing helps assess. A single pinhole in an otherwise sound line suits a spot repair; a corroded system with multiple weak points often favors rerouting overhead. We document the findings so you and your contractor can decide with full information — we do the locating, not the repair.
Many policies cover the resulting water damage, though coverage for detection and pipe repair varies. Our reports include thermal images, pressure readings, and marked-spot photos built to support claims. Customers regularly tell us the documentation made the process straightforward; your insurer makes the final decision.
Yes — we answer 24/7, every day of the year, and arrive in 30–45 minutes anywhere in Broomfield. A spreading warm spot or the sound of water under the floor should not wait for morning; call (720) 715-9734 now.
Yes. We serve all of Broomfield including the 80020, 80021, 80023, and 80038 ZIP codes, and slab calls get the same thermal-acoustic pinpointing in every neighborhood.
No — pressurized leaks only grow. Water under pressure enlarges the break over time and erodes soil beneath the foundation, turning a pinhole into structural risk. Early pinpointing keeps the repair to one small opening; delay is what turns slab leaks expensive.
