What is a slab leak?

A slab leak is a leak in a water or drain line that runs beneath or inside a concrete floor. In Littleton that floor is often a basement slab, a garage slab or the lower level of a split-level, as well as true slab-on-grade ranches and townhomes. Because the pipe is buried, the leak can run for weeks before you notice anything — and by then water may have soaked into the soil, the flooring or the walls.

There are two main kinds:

• Supply-line leaks — pressurized hot or cold water lines. These raise your water bill and, for hot lines, often cause warm spots on the floor.
• Drain-line leaks — waste and sewer pipes under the slab. These don't raise the water bill but can cause odors, damp floors and settling.

Our slab leak services in Littleton

Every slab leak needs two things done well: finding it and choosing the right fix. Here's everything we offer.

How do you know if you have 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 we fix slab leaks — our process

1. You call, we answer. Day or night, a person picks up and asks the right questions — what you're seeing, how long, and whether water is surfacing.
2. Stop the damage. If it's urgent, we walk you through shutting off the main and the water heater while we're on the way.
3. Find the leaking line. Meter check and pressure isolation tell us whether it's hot, cold or drain.
4. Pinpoint it. Acoustic listening, thermal imaging and line tracing mark the leak on your floor, usually to within about a foot.
5. Compare options in writing. Spot repair, reroute, lining or repipe — with prices and honest trade-offs.
6. Repair, test, restore. We do the work, pressure-test it and leave the area clean.

Spot repair, reroute or lining — which is best?

Our rule of thumb: if it's your home's first leak and the pipe looks good, a spot repair is often fine. If it's the second leak — or the pipe is 40+ years old — we'll show you a reroute price too.

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.

How much does slab leak repair cost in Littleton?

What drives the price up or down?

• Floor covering. Carpet is cheap to pull back; tile and hardwood are not.
• Depth and location. Lines under footings, cabinets or deep fill take more work.
• Pipe condition. Corroded pipe pushes toward reroute or repipe.
• Permits. Many jurisdictions require them for reroutes and repipes.
• Time of day. After-hours emergency visits may carry an extra fee — we tell you on the phone first.

What should you do in a slab leak emergency?

If water is coming up through the floor, every minute matters. Our 24/7 emergency slab leak service is staffed around the clock.

Does insurance cover slab leaks in Colorado?

Many homeowners policies cover sudden water damage and the cost to access the pipe — breaking and replacing the floor — but not the pipe repair itself. Some cap slab-leak coverage. We give you photos, readings and a written report showing where the leak was and what caused it, which is what adjusters ask for. Always check your own policy.

Slab leaks by age of home

Littleton's housing stock spans more than a century, and the age of your home tells us a lot before we even arrive.

What should you look for in a slab leak company?

• They locate before they cut. Ask what detection equipment they use.
• They offer more than one fix. If you only hear "we'll jackhammer," ask about reroutes and lining.
• They put prices in writing before work starts.
• They answer the phone when you need them, including nights.
• They document the job for your insurer.

How to reduce your risk of a slab leak

• Know your shutoff. Find and tag your main valve now.
• Watch your meter. Check the leak dial every few months.
• Manage water pressure. Very high pressure stresses old pipe; a pressure-reducing valve may help.
• Keep water away from the foundation. Good grading and downspouts help keep clay soil stable.
• Plan ahead in older homes. If your copper is 40+ years old, budget for a reroute or repipe before the next leak forces it.

What our customers can expect on every job

From the first call, you'll know who is coming, roughly when, and what the visit will cost before we arrive. On site, our technician explains what they're testing and why, shows you the readings, and marks the leak where you can see it. You'll get written options and time to decide, and once you choose, we protect your floors, contain the dust and clean up when we're finished.

A typical Littleton slab leak call, start to finish

Here's how a common call goes. A homeowner in a 1970s split-level notices the lower-level tile feels warm near the kitchen and the gas bill jumped. They call at 9 p.m.; we tell them to shut the cold inlet on the water heater and switch it to vacation. Next morning our technician confirms the hot side is losing pressure, traces the line and uses thermal imaging to find the warm plume under the kitchen tile. Because the copper is original and the floor is tile, we price both a spot repair and a hot-line reroute through the floor framing between levels. The homeowner picks the reroute, the work is done in a day, and the tile never gets touched.

Not every job looks like this — some are a quick spot repair in a garage, others a full repipe — but the order never changes: confirm, locate, explain, then repair.

Slab leak myths we hear often

• "Slab leaks always mean jackhammering." Reroutes and lining often avoid it entirely.
• "If I don't see water, it's not serious." Most slab leaks drain into the soil and stay invisible for weeks.
• "Newer homes don't get slab leaks." They do, though less often and usually for different reasons.
• "Insurance pays for everything." Many policies cover damage and access, not the pipe repair itself.
