graham/leak-and-slab-detection

Not every hidden leak is under the slab. In Graham we also trace leaks inside walls, where a slow supply-line drip soaks insulation and framing; under yards, where the service line from the meter runs; and in pools and irrigation, which can masquerade as house leaks on the water bill. Our Leak & Slab Detection covers the whole property: we isolate zones with pressure tests to learn which part of the system is losing water, then narrow it with acoustic and thermal tools until the location is certain.

Do not let anyone jackhammer your slab on a guess. A reputable detection ends with a marked location backed by readings, and the repair opening is small and targeted. If a contractor wants to open concrete without acoustic or thermal confirmation, get a second opinion first. Ours starts at (833) 834-1087.

How leak detection works

Yard service-line leaks, between the meter and the house, have their own tells: a perpetually green or soggy strip, a meter that spins with the house shutoff closed, the sound of running water at the meter box. Detection here combines the meter isolation test, acoustic listening along the line’s path, and sometimes tracer gas: the line is filled with a safe hydrogen-nitrogen mix, and a sniffer at the surface finds where it escapes. Because Piedmont Triad soils shift with moisture, service lines here fail at joints and where they enter the foundation, and the locator marks both the leak and the line’s path so the repair trench is exactly as long as it needs to be.

Signs you need leak detection in Graham

• Mildew smells or mold growth on a ground-floor wall.
• Low water pressure that appeared gradually across the house.
• A water bill that jumps with no change in usage.
• Water beading on a hose bibb in spring, long after the last freeze, reveals a split hidden inside the wall.
• The same drain clogging again weeks after a cleaning usually means roots have re-entered through a lateral joint.

What’s included

• Detection for hot and cold supply lines
• Wall and ceiling leak tracing with moisture mapping
• Yard service-line locating and leak pinpointing
• Tracer-gas methods for difficult underground leaks
• Coordination with the repair crew so nothing is re-diagnosed

Piedmont Triad: how local conditions affect leak detection

Newer Graham subdivisions on slab foundations hide their leaks beneath concrete, where pressurized lines face flexing clay and moderately hard water. Pinholes open at stress points and announce themselves indirectly: a warm floor patch, water sounds with taps closed, flooring buckling near the slab edge. Acoustic and thermal detection pinpoint the break so repair opens one precise spot instead of trenching the floor. Early location matters doubly under a slab; the leaking water erodes supporting soil while the repair clock runs. A found leak is a manageable repair; an unfound one undermines the foundation itself.

The joint where the sewer lateral meets the foundation takes the full force of Graham’s swell-and-shrink clay cycle, year after year. The rigid house does not move; the soil does, and the connection flexes until the joint opens and wastewater seeps into the ground. Detection looks for the quiet signs: a damp strip along the foundation that never dries, unusually lush grass tracing the lateral, a faint odor after rain. Dye testing and camera work confirm the connection as the source. Repairing that single joint often resolves what presented as a whole-system drainage problem.

Winter freezes send Graham leak detection into crawl spaces, where split supply lines wait out the cold in silence. Ice bursts the pipe during the freeze; the thaw restores pressure and water pours into the under-house space, sometimes for hours before discovery. Detection is a methodical crawl-space survey, moisture meters, bright light, tracing wet insulation back to each break. Freeze events often split multiple sections, so the search continues past the first find. Every split gets repaired, and the exposed runs get insulated and protected, because Graham winters will test that same plumbing again.

What affects the cost of leak detection in Graham

Access drives labor on leak repairs more than the pipe itself. A leak under an open garage slab is straightforward; the same leak under a finished kitchen with stone tile means careful removal, protection, and restoration of expensive finishes. Wall leaks behind tile showers or built-ins take similar care. We price the access honestly: the protection, the surgical opening, and the restoration to a paint-ready or tile-ready state. The pipe repair in the middle is often the quickest part of the job.

• What sits above the leak: flooring type and finishes
• Protection and dust control during the work
• Surgical opening size versus exploratory demolition
• Restoration to finished condition

Common questions

How do you find a leak under concrete?

Acoustic sensors, thermal imaging, and pressure tests triangulate the spot. We open concrete only where the leak actually is, and the opening is small and targeted.

Is a slab leak an emergency?

It can wait days, not months. Unchecked leaks erode soil under the slab and invite foundation trouble, so this week beats next month.

What does leak detection cost?

The detection visit is flat-rate and includes the full investigation plus a written report. The repair is quoted separately once we know what and where the problem is.

Can you detect leaks in walls too?

Yes. Moisture mapping and thermal imaging trace wall and ceiling leaks to their source, and we open surgically once, in the right place.

Why does the same drain clog in the same spot every time?

A clog that returns to the identical spot is not a coincidence; something structural lives at that location. Pine roots entering through a separated lateral joint regrow after every cutting, so the blockage reforms at the entry point. A belly or offset in the pipe collects waste at the same low point after each clearing. Even heavy cast-iron scale creates a permanent snag point that catches paper again and again. Repeated clearing treats the symptom while the cause stays in place. A camera inspection identifies which structural problem owns that spot, and only repairing the pipe itself breaks the cycle of recurring clogs.
