Slab leaks and monsoon damage: repairs that hold

Quick answer

Signs of a slab leak include a water bill that jumps for no reason, a meter that keeps moving with every tap off, a warm spot on the floor, the sound of running water when nothing is on, damp carpet or new cracks in tile. Any one of them is worth a meter test.

Water does the most damage in the desert precisely because nobody expects it. Most valley homes are built slab-on-grade, with water lines running through or under the concrete. When one of those lines leaks, the water goes into the slab and the soil, and often shows up first under the kitchen cabinets or flooring. And every few summers, a storm drops months of rain in an afternoon.

This guide covers both kinds of water problems, slab leaks and storm damage: how to spot them, what repairs cost, what insurance usually does, and how to rebuild a kitchen so it's stronger than before.

Part 1: slab leaks

The signs

• A water bill that jumps with no change in how you use water.
• A meter that moves with every fixture off. Turn off every tap, the irrigation and the ice maker, then watch the meter's leak indicator for 15 minutes.
• A warm spot on the floor, often a hot-water line leaking under tile.
• The sound of running water when nothing's on.
• Damp, musty carpet or baseboards, or swelling at the bottom of a base cabinet or toe-kick.
• New cracks in floor tile, or a water heater that seems to run all the time.

If the meter is moving, call a plumber or a leak detection specialist. They locate leaks with acoustic listening equipment, thermal imaging and pressure testing, so the slab is opened in one spot instead of five.

Hard water and age are commonly blamed for pinhole leaks in older copper lines, though a leak can have many causes. If your home has had one slab leak, ask the plumber about the condition of the rest of the system.

Repair options compared

National cost figures give a rough sense of scale. HomeAdvisor puts typical slab leak repair at $630 to $4,400, averaging about $2,280, and slab leak reroutes at about $600 to $4,000 (HomeAdvisor). These are national ranges for the plumbing work; they don't include leak detection, or replacing the flooring, cabinets and drywall that came out to reach the pipe. Get written quotes from licensed plumbers after the leak is located.

Replacing pipe is permitted plumbing work in the valley; stopping a leak is generally exempt, replacing the pipe isn't. See our permit guide.

When the leak is under the kitchen

This is where a slab leak becomes a kitchen project. Before anything is put back:

• Dry it properly. Moisture readings on the slab and framing before cabinets or flooring go back. The EPA advises drying wet materials within 24 to 48 hours to prevent mold (EPA, mold cleanup).
• Check the cabinets honestly. Particleboard boxes that got wet usually swell and don't recover. Plywood boxes sometimes can be dried and kept.
• Consider a reroute while the kitchen is open. If you're already replacing cabinets or floors, running new lines overhead costs less now than later.
• Upgrade the weak points: moisture-resistant cabinet boxes and toe-kicks, a leak sensor or automatic shutoff valve, and new shutoff valves at the sink and fridge.
• Match or replace flooring. Discontinued tile is common. Plan for a transition, or for a larger flooring replacement.

Your water bill

If a verified leak sent your bill up, ask your water agency about an adjustment. CVWD, for example, reviews accounts for high consumption with a verified cause such as a leak on the customer's property (CVWD account review). Keep the plumber's invoice as proof.

Part 2: monsoon and storm damage

What the valley's storms do

Summer brings monsoon moisture surges and, occasionally, the remains of Pacific tropical storms (Wikipedia, Coachella Valley). Tropical Storm Kathleen in September 1976 caused widespread destruction, especially in the east valley. In August 2023, Hurricane Hilary dropped 3.18 inches of rain on Palm Springs, about 69% of its average yearly total. Floodwater displaced at least 30 residents in Palm Desert's Spanish Walk neighborhood, entered a nursing home in Cathedral City and reached Eisenhower Medical Center in Rancho Mirage, and about 30 miles of I-10 closed for two days (Wikipedia, Hurricane Hilary).

Typical damage after a storm:

• Water through flat or low-slope roofs, scuppers and roof penetrations
• Water under sliding doors and through older windows
• Runoff into garages and ground-floor rooms
• Wet lower cabinets, toe-kicks and flooring
• Wind-driven dust and debris in HVAC systems and on everything else

The first 48 hours

1. Stay safe. Turn off power to wet areas if you can do it safely. Don't walk through standing water near outlets.
2. Stop the water and move what you can out of the wet area.
3. Photograph everything before cleanup: water lines on walls, wet cabinets, damaged belongings. Keep damaged items until the adjuster has seen them, if you can.
4. Call your insurer and start a claim.
5. Start drying. Fans, dehumidifiers or a water mitigation company. The EPA's 24-to-48-hour guidance applies here too.
6. Then get repair quotes, from licensed contractors, in writing.

If you're away for the summer, this is exactly the job for a local contact. Our guide to remodeling while you're away covers setting one up.

Insurance, in plain terms

• Standard homeowners policies generally exclude flood from surface water, like storm runoff entering the house. That's covered by separate flood insurance, if you have it.
• Wind-driven rain and roof leaks may be covered, depending on the policy and the cause.
• Sudden pipe leaks are often covered for the resulting damage; worn-out pipe and slow, long-term leaks often aren't.
• Read your policy's water-damage and access (“tear-out”) language, and ask your agent before you assume.

We're not insurance advisers; your agent and policy decide what's covered.

Protect yourself from storm chasers

After big storms, door-to-door “contractors” follow. California gives you extra protection:

• Seven business days to cancel a home improvement contract for repairs after a declared disaster, rather than the usual three (Civil Code section 1689.6).
• The down payment cap still applies: 10% of the price or $1,000, whichever is less.
• Check the license at cslb.ca.gov. Contracting without a license in a declared emergency area carries much stiffer penalties than usual.
• Never sign over your insurance check or let a contractor deal with your insurer without a written agreement you understand.

Common questions

What are the signs of a slab leak?

A water bill that jumps for no reason, a meter that keeps moving with every tap off, a warm spot on the floor, the sound of running water when nothing is on, damp or musty carpet, new cracks in tile, or a water heater that runs constantly. Any one of them is worth a meter test.

How much does slab leak repair cost?

Nationally, HomeAdvisor puts typical slab leak repair at $630 to $4,400, with an average around $2,280, and a reroute at about $600 to $4,000. Those are national figures for the plumbing alone. Detection, flooring, cabinets and drywall repair are extra, and a valley repair can land anywhere in or beyond that range depending on access.

Should I reroute or fix the pipe under the slab?

Spot repair breaks the slab at the leak and fixes that section; it's often cheaper for one leak in otherwise sound pipe. A reroute abandons the line under the slab and runs new pipe through walls or the attic, avoiding more slab work later. With aging pipe or repeat leaks, a reroute or a full repipe is usually the better long-term answer.

Does homeowners insurance cover a slab leak?

It depends on your policy. Many policies cover sudden water damage and sometimes the cost of accessing the pipe, but not the repair of the worn pipe itself or damage from a slow, long-term leak. Flood from surface water, like storm runoff, is generally excluded from standard homeowners policies and needs separate flood insurance.

How quickly do I need to dry out water damage?

The U.S. EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. In practice, that means stopping the water, documenting the damage, and getting fans, dehumidifiers or a mitigation company in right away.

Can a contractor make me sign right after a storm?

They can ask, but don't rush. In California you have extra time to cancel a home improvement contract for repairs after a declared disaster: seven business days, rather than the usual three. Check the contractor's license at cslb.ca.gov before you sign anything.

My condo has a slab leak. Who pays?

Check your CC&Rs. Under California Civil Code section 4775, unless the declaration says otherwise, the association generally maintains and repairs the common area and each owner maintains their own unit. Pipes in a shared slab may be common area. Call your management company before hiring anyone.
