A slab leak is a break in a water or drain line that runs under or inside your home's concrete floor. In Littleton, we fix them three main ways: open the slab at the exact leak point, reroute the line through walls and ceilings so the old pipe is abandoned, or coat the inside of the pipe with epoxy. Which one is right depends on where the leak is, how old the pipe is, and what is on the floor above it.

We have been doing this work around Littleton since 2015, with more than 3,600 jobs behind us. The process below is the same one we use on every call, whether it is a pinhole in a 1970s ranch off Bowles Avenue or a split PEX line in a newer home near Sterling Ranch.

How do we repair a slab leak, step by step?

  1. Confirm the leak. We shut off fixtures and watch the meter, then isolate hot and cold sides with pressure gauges. This tells us which line is leaking before anyone touches the floor.
  2. Locate it. Acoustic ground microphones, thermal imaging and line tracing narrow the leak to about a foot. See slab leak detection for how that works.
  3. Lay out your options. You get a written price for each realistic repair method, with the trade-offs explained — not just the most expensive one.
  4. Protect the house. Floor coverings are pulled back carefully, dust barriers go up, and furniture is moved before any saw comes out.
  5. Repair. We open the slab, reroute, or line the pipe — whichever you chose.
  6. Pressure-test. The repaired line is tested before anything is closed back up.
  7. Restore. Concrete is re-poured and leveled, or wall openings from a reroute are closed and ready for paint.

Which repair method is right for your home?

There is no single best repair. Here is how the three methods compare on the things homeowners ask about most:

MethodBest forFloor disruptionTypical timeline
Spot repair through slabOne leak on otherwise healthy pipeSmall opening, about 2×2 ft1–2 days plus concrete cure
Pipe rerouteOlder copper, repeat leaks, leak under cabinets or tileNone to the floor; small wall openings1–2 days
Epoxy pipe liningPinhole corrosion along a run, hard-to-reach linesMinimal1–3 days
Whole-house repipeMultiple failures, aging copper throughoutWall and ceiling openings2–5 days

When we recommend a spot repair

If the pipe around the leak is in good shape and the leak sits under an easy floor — carpet over a basement slab, or a garage — opening the slab is usually the cheapest and fastest fix.

When we recommend a reroute

If your home has already had one slab leak, or the copper is thin and pitted, a second and third leak often follow. Rerouting the affected line overhead avoids that and spares tile and hardwood floors.

When lining makes sense

Lining works well when the pipe is structurally sound but corroding from the inside. It is not right for a line that is crushed, separated or badly misaligned.

Water bill climbing or a warm spot on the floor?

Every hour a slab leak runs, more water goes into the soil under your home. Call now and we'll send a technician with leak-locating gear, day or night.

Why do slab leaks happen in Littleton homes?

Littleton's housing stock tells most of the story. A large share of homes went up during the building boom of the 1960s through the 1980s, and many of them have copper water lines buried in or under a concrete floor — a basement slab, a garage slab, or the slab of a ranch or split-level that sits on grade. Newer subdivisions on the south and west sides were often plumbed with PEX, which fails differently but can still be damaged under concrete.

  • Expansive clay soil. Much of the Front Range sits on clay that swells when wet and shrinks when dry. That seasonal movement pushes and pulls on pipes locked in concrete, and fittings and bends take the strain first.
  • Abrasion. A copper line that rests against gravel, rebar or the edge of the slab vibrates every time water flows. Over decades it rubs a hole through its own wall.
  • Water chemistry and age. Pinhole corrosion from the inside is common in older copper. Once one pinhole appears, others along the same run often follow.
  • Freeze-thaw and construction defects. Lines that run near an exterior wall, a crawl-space transition or a poorly bedded trench are more exposed to stress.

What are the warning signs of a slab leak?

Most homeowners call us because of one of these, often two at once:

  • A water bill that jumps with no change in habits, or a water meter that keeps spinning with every fixture off
  • A warm or hot patch on tile, vinyl or carpet — the classic sign of a hot-water line leak
  • The sound of running water when nothing is on, often loudest at night
  • Damp or musty carpet, lifting laminate, cupping hardwood or efflorescence (white crust) on a basement floor
  • New cracks in the slab or in drywall near the floor
  • Low water pressure at one fixture or across the house
  • A water heater that runs constantly, or a sudden jump in your gas bill

How much does slab leak repair cost in Littleton?

Price depends far more on access than on the leak itself. A leak under carpet in a basement costs much less to reach than the same leak under a kitchen island set on tile.

JobTypical Littleton range
Leak detection and location$250 – $650
Spot repair through slab (incl. concrete patch)$1,500 – $4,500
Reroute one line (hot or cold)$2,000 – $6,500
Epoxy lining, one line$3,500 – $9,000
Whole-house repipe (PEX)$6,500 – $18,000
Flooring removal and replacementVaries — often billed separately

Will homeowners insurance cover a slab leak?

Often partly. Many Colorado policies cover the water damage a sudden leak causes and the cost of tearing out and replacing the floor to reach it, but not the pipe repair itself. Some policies have specific slab-leak limits. We document the leak location with photos and readings so you have what your adjuster needs. Check your own policy — every carrier is different.

What happens if you ignore a slab leak?

A small leak under concrete rarely stays small. Water follows the path of least resistance through gravel and soil, and in Littleton's clay it can make the ground swell under one part of the slab while washing fine soil away under another. Left for months, that can mean cracked tile, sticking doors, mold under carpet and pad, and a much larger repair. Waste is the other cost: a steady pinhole leak can send thousands of gallons into the ground over a billing cycle, and a hot-water leak burns fuel the whole time.

Questions to ask any slab leak contractor

  • How will you confirm which line is leaking before opening the floor?
  • What equipment do you use to pinpoint the leak?
  • What are all my repair options, and what does each cost in writing?
  • Who restores the concrete and the drywall, and is that included?
  • Will I get photos and readings for my insurance claim?

Slab leak repair in townhomes and condos

Attached homes share slabs and walls, so a leak may cross unit lines and responsibility may fall to you, a neighbor or the HOA. We test from your unit, identify which line is leaking and which unit it serves, and document it clearly. Lining or an in-unit reroute often avoids opening a shared slab.

Slab leak repair FAQ

How long does a slab leak repair take?

Most spot repairs and single-line reroutes are finished in one or two days. New concrete needs a few days before flooring goes back down. A whole-house repipe typically takes two to five days.

Can a slab leak damage my foundation?

It can. Water running into clay soil can make it swell or wash fines away, which may lead to settling or heaving. That is why we recommend fixing leaks quickly rather than waiting.

Do I need to move out during repairs?

Almost never. We isolate the leaking line, so you usually keep water to the rest of the house, and work areas are sealed off with dust barriers.

Can a slab leak fix itself?

No. Leaks under concrete only grow as the water erodes soil and the pipe continues to corrode.

Do you work on homes with basements?

Yes. Many Littleton slab leaks are in basement slabs or garage slabs rather than single-story slab-on-grade homes. The detection and repair process is the same.
