Signs of a slab leak

Slab leaks hide under concrete, so you notice the symptoms before the source. Call for detection if you see:

  • A warm or damp spot on the floor (hot-water line)
  • The sound of running water with everything off
  • An unexplained jump in your water bill
  • Low water pressure throughout the house
  • New cracks in flooring, tile, or walls
  • A musty or mildew smell, or buckling flooring

Not sure where it's coming from? Start with leak detection — we confirm and locate before any repair.

Suspect a slab leak now?

  1. Note the warm spot or damp area — it helps us locate fast.
  2. Check the meter: shut all fixtures; if it still moves, water's escaping.
  3. Shut the main if water is actively pooling or spreading.
  4. Call (971) 399-8934 — we detect and repair, day or night.
Detect & repair

How we fix a slab leak

We locate precisely, then choose the most durable, least destructive repair for your home.

Electronic Detection

Acoustic, thermal, and pressure tools pinpoint the leak before any concrete is touched. Leak detection

Spot Repair

Open the slab at the exact leak, repair the pipe, and restore the concrete — minimal footprint.

Reroute / Bypass

Abandon the failed under-slab run and reroute the line through walls or attic — no slab demo.

Repipe

For repeated failures, repipe the affected lines for a long-term fix. Repiping

Hot & Cold Lines

Pressurized supply slab leaks on either hot or cold lines located and repaired.

Concrete Restoration

We patch and finish any concrete we open so the floor is sound and clean again.

Spot repair vs. reroute

Spot repair is ideal for a single, accessible leak — fix it and move on.

Reroute or repipe is the smarter call when the pipe is old, has failed before, or sits where opening the slab would be very disruptive — bypassing the under-slab run prevents the next leak in the same line.

We base the recommendation on the pipe's age and condition, not on what's quickest for us.

Portland-specific

Why slab leaks happen here

Homes built on concrete slabs — common in mid-century and newer Portland-area construction — run supply lines in or beneath the slab. Over decades, copper corrodes, pipes abrade against concrete and rebar as the house settles, and pressure and soil movement do the rest.

The Pacific Northwest's wet ground and seasonal shifting accelerate that movement, so an aging slab home is a prime candidate for a leak underfoot.

Whatever the cause, we find it fast and tell you honestly whether a spot fix or a reroute is the better long-term value.

Slab Leak Guide

Concrete foundation slab where a Portland plumber located a slab leak Pinpointthen repair

The leak you can't see is the costly one

Because a slab leak runs under concrete, the water works on your foundation, flooring, and air quality before you ever spot a puddle. Catching it early — at the warm-spot or bill-spike stage — is the difference between a contained repair and a foundation-and-flooring project.

Locate first, cut once

We never jackhammer a slab to "go looking." Electronic detection pinpoints the leak so we open one small area or bypass the line entirely. Less concrete, less mess, lower total cost.

How slab leaks get fixed

Once we've located the leak, you choose from clear options:

  • Spot repair — open the slab at the leak and repair the pipe
  • Reroute — bypass the under-slab run through walls or attic
  • Repipe — replace failure-prone lines for a permanent fix
  • Full concrete restoration on anything we open
  • Documentation for your insurance claim

Don't let it run

A slab leak only gets more expensive: it undermines the foundation, feeds mold, and — on a hot-water line — burns energy around the clock. A live dispatcher answers any hour, so you can stop the damage tonight instead of watching it spread until morning.

Many Portland slab homes were plumbed in copper that's now decades old, and once one section corrodes through, others on the same line often follow. That's why we're candid about when a reroute or partial repipe is the better value than chasing one spot repair after another.

Every detection and repair is performed by an Oregon-licensed, background-checked plumber and backed by a written guarantee, at the same flat rate whether we locate a leak at noon or at 2 a.m. — no after-hours surcharge.

Slab Leaks, Answered

More slab leak questions in Portland

How serious is a slab leak if I ignore it?

Serious enough that it shouldn't wait. Water escaping under the slab erodes the soil that supports your foundation, can lead to cracking and settling, and feeds mold in the floor and walls — while a hot-water slab leak also burns energy continuously. What starts as a small warm spot or a bumped-up water bill becomes structural and air-quality damage the longer it runs. Catching it early keeps it a contained repair instead of a foundation problem.

Will fixing a slab leak mean jackhammering my floor?

Not the way people fear. Because we pinpoint the leak first with acoustic and thermal detection, any opening in the slab is small and precise — right at the leak, not exploratory. Better yet, we can often avoid breaking the slab entirely by rerouting that line through the walls or attic to bypass the failed section. We always present the least destructive option that actually solves it.

Can a slab leak affect my home's foundation?

Yes, over time. Persistent water under a concrete slab washes out and softens the supporting soil, which can cause the slab to crack, heave, or settle unevenly — you might notice new cracks in floors or walls, or doors that stop closing right. That's exactly why we treat slab leaks as time-sensitive: stopping the water early protects the structure, not just the plumbing.

How long does slab leak repair take?

An accessible spot repair is often completed in a day once the leak is located. A reroute or partial repipe takes longer depending on the run, and any concrete we open needs time to be patched and cured. We give you a realistic timeline with the flat quote, and because detection is non-invasive, the diagnosis itself is quick — usually the same visit.

How can I prevent slab leaks?

You can't control aging copper under a slab, but you can reduce the risk: keep household water pressure in a safe range (high pressure accelerates pipe failure), address small leaks and corrosion early, and watch for the warning signs — a warm floor spot, an unexplained bill increase, or the sound of running water. If your slab home has original copper and you've had one leak, others on the same line often follow, which is when a reroute makes sense.

FAQ

Slab leak repair questions

Suspect a leak under the slab? Call and we'll confirm and locate it — any hour.

What is a slab leak?

A slab leak is a water or sewer pipe leaking beneath the concrete foundation your home sits on. The water has nowhere to go but into the foundation and up through the floor, which is why slab leaks cause expensive damage if left unaddressed.

What are the signs of a slab leak?

A warm or damp floor spot, the sound of running water with everything off, a spike in your water bill, low pressure, new cracks in flooring or walls, a moving meter with all fixtures shut, or a musty smell. Any of these warrants leak detection right away.

How do you find a slab leak without breaking the whole floor?

We use non-invasive electronic detection — acoustic listening, thermal imaging, and pressure testing — to pinpoint the leak before opening anything. We access one small spot instead of jackhammering the slab to search.

How is a slab leak repaired?

Depending on location and pipe condition, we open the slab for a spot repair, reroute the line through walls or attic to bypass the slab, or repipe the affected run. For multiple failures, a reroute or partial repipe is often most durable. We explain the trade-offs first.

How much does slab leak repair cost in Portland?

Detection typically runs $150–$450, and repair ranges from about $1,000 for an accessible spot fix to $4,000+ for reroutes or repipes with concrete work. We quote a flat price before work and apply detection toward the repair. Financing available.

Is a slab leak an emergency?

It can be. A slab leak undermines the foundation and feeds mold the longer it runs, and a hot-water slab leak wastes energy continuously. If you see fast-spreading damage or a sudden hot spot, treat it as urgent — a live dispatcher answers 24/7.

What causes slab leaks?

Corrosion of copper or galvanized pipe, abrasion where pipes rub the slab or rebar as the house shifts, high water pressure, poor original installation, and soil movement. Older Portland slab homes and those with aging copper are the most common cases.

Will my insurance cover a slab leak?

Many policies cover accessing and repairing the slab (tear-out and repair) even when they don't cover the pipe itself, but it varies. We provide detailed documentation to support your claim; coverage is determined by your insurer.
