What it is

What is Slab Leak?

A slab leak is a water line break in the copper pipes running underneath your home’s concrete foundation. Tempe homes typically have hot and cold water lines embedded in or just below the slab, and when one of those lines pinholes, cracks, or bursts, water escapes directly into the soil beneath your floors.

Unlike a visible pipe leak you can spot and patch, slab leaks hide under concrete, drywall, and flooring. Left alone, they erode soil, crack foundations, and rot subflooring. The longer you wait, the worse the damage gets and the higher the repair bill climbs.

Why Tempe

Why Tempe Homes Are Prone to Slab Leaks

Tempe’s combination of older housing stock, expansive clay soils, and aggressive water chemistry creates the perfect storm for slab leaks. Hover any card to learn more.

Hard Water

Pinhole corrosion

Hard Water Pinholes

Tempe's hard water erodes copper from the inside out. Pinhole leaks start small but multiply once one line goes.

Soil Movement

Expansive clay

Shifting Foundation Soil

Tempe's clay-heavy soil expands when wet and contracts when dry. The constant pressure stresses copper lines until they crack.

Old Copper

1970s-1990s homes

Aging Copper Lines

Many Tempe homes built between 1970 and 1995 have thin-wall Type M copper under the slab, well past its expected lifespan.

Abrasion Wear

Pipe friction

Abrasion Against Concrete

Copper lines rub against concrete and rebar with every thermal expansion cycle. Over decades, the friction wears holes straight through.

Frequently Asked Questions

How do I know if I have a slab leak in my Tempe home?
+

Warning signs include unexplained spikes in your water bill, warm or hot spots on the floor (usually a hot water line leak), the sound of running water when nothing is on, low water pressure, cracks in flooring or drywall, mildew smells, and visible water seeping up through the slab. If you notice any combination of these, call for a free leak detection.

How much does slab leak repair cost in Tempe?
+

Slab leak repair in Tempe typically ranges from $1,500 for a simple spot repair to $4,500 or more for a full reroute. Cost depends on leak location, accessibility, repair method, and whether flooring or drywall restoration is needed. We provide free detection and a written quote before any work begins.

Can you fix a slab leak without breaking my floor?
+

Often, yes. Rerouting the affected line through walls or the attic avoids breaking concrete entirely. For leaks in accessible areas, we may recommend a spot repair through a small slab opening. For homes with multiple aging lines, a full repipe is the most cost-effective long-term fix.

How long does slab leak repair take?
+

Detection typically takes 1 to 2 hours. A spot repair is usually done in a single day. A reroute takes 1 to 2 days, and a full repipe runs 2 to 5 days. Water service is restored every evening regardless of project length.

Will my homeowners insurance cover the slab leak?
+

Most Tempe homeowners insurance policies cover the water damage caused by a slab leak (drywall, flooring, contents) but not always the pipe repair itself. We provide detailed documentation, photos, and a written diagnosis to support your claim. Call your carrier as soon as you suspect a leak.
