If you think you might have a slab leak, call us today to set up an inspection.

What Is a Slab Leak?

Most homes in Allen have concrete slab foundations. Under the concrete, pressurized water pipes supply your sinks, showers, appliances, and outdoor faucets.

Over time, these pipes can develop problems. Common reasons include:

• Corrosion inside older copper lines
• Shifting soil under the foundation
• High water pressure
• Poor initial pipe installation
• Abrasion from pipe movement against concrete

If one of these pipes leaks, water escapes under your foundation. Since the leak is hidden, you’ll usually notice other warning signs before you see any water.

This is why it’s important to have a professional check for slab leaks.

Signs You May Have a Slab Leak

Slab leaks rarely appear as puddles on the floor. Instead, the signs often show up slowly over time.

Here are the most common signs that homeowners in Allen notice:

Unexplained Increase in Water Bills

If you haven’t used more water but your bill keeps going up, you could have water leaking underground.

Warm Spots on Flooring

Leaks in hot water lines can cause warm spots on tile or wood floors.

Cracks in Walls or Flooring

Water under your foundation can move the soil and cause your home to shift.

Sound of Running Water

If you hear water running when nothing is turned on, it could be moving under the slab.

Musty Odors or Mold Growth

Moisture under floors or behind walls can cause musty or mildew odors.

If you notice any of these signs, it’s a good idea to have a professional check your plumbing.

Why Slab Leaks Are Serious in Allen Homes

The soil in North Texas affects how stable your foundation is. In Allen, the clay soil expands when it’s wet and shrinks when it’s dry. This movement puts stress on both your foundation and the pipes below it.

If a slab leak keeps the soil under your foundation wet, the ground can shift unevenly. Over time, this can cause:

• Foundation settlement
• Interior wall cracking
• Door and window misalignment
• Flooring damage
• Mold growth

The longer a leak goes on, the more costly repairs can get. Finding the problem early can help prevent serious damage.

That’s why it’s important for Allen homeowners to schedule an inspection as soon as possible if they suspect a slab leak.

Our Slab Leak Detection Process

Before starting any repairs, we need to confirm and find the exact location of the leak.

We follow a careful, step-by-step process:

1. Pressure Testing

We test the plumbing system to confirm whether a leak exists and determine if it’s on the hot or cold line.

2. Isolation Testing

We isolate sections of plumbing to narrow down the leak’s location.

3. Electronic Leak Detection

We use special listening and locating tools to find the leak under the slab without tearing up more than needed.

We focus on being accurate. If you break concrete without knowing exactly where the leak is, repairs get bigger and more expensive. Careful leak detection helps keep the work as small as possible.

Slab Leak Repair Options

After we find the leak, we’ll explain your repair options. Every situation is different, so we’ll help you choose what works best.

Spot Repair

If we can reach the pipe easily and the rest of the plumbing is in good shape, we might suggest a direct repair.

This involves:

• Opening a small section of concrete
• Repairing or replacing the damaged pipe section
• Restoring the slab

Spot repairs are a good choice when the leak is in one place and the rest of your plumbing is in good condition.

Pipe Rerouting

Sometimes, especially in older homes with old copper pipes, rerouting the problem line is a better long-term fix.

Instead of fixing the pipe under the slab, we can:

• Install a new line through walls or ceilings.
• Bypass the damaged underground pipe.

Rerouting helps lower the chance of more slab leaks in the same area.

Tunneling (If Appropriate)

For some homes, tunneling under the foundation lets us reach the pipes without breaking up your floors inside.

This approach depends on:

• Foundation design
• Leak location
• Soil conditions

We’ll let you know if tunneling is a good option for your home.

How Long Does Slab Leak Repair Take?

How long repairs take depends on the method we use.

• Leak detection: Usually completed within a few hours
• Spot repairs: Often 1–2 days
• Rerouting: May take longer depending on the layout

Once the plumbing is fixed, it may take extra time to restore things like flooring or drywall.

We’ll give you a clear estimate before we start, so you’ll know what to expect.

Will Insurance Cover Slab Leak Repair?

Coverage varies by policy.

In many cases:

• The plumbing repair itself may not be covered.
• Damage caused by the leak may be covered.

We suggest checking your homeowner’s policy or talking to your insurance company. If you need it, we can give you paperwork about the leak and repairs.

Frequently Asked Questions

How do I confirm I have a slab leak?

The best way to confirm a slab leak is with professional pressure testing and electronic detection. Surface signs by themselves aren’t enough to be sure.

Can a slab leak cause foundation damage?

Yes. If water keeps leaking under the slab, it can move the soil and cause your foundation to shift if not fixed.

Is breaking through the floor always required?

Not always. Some leaks can be fixed by rerouting pipes or by tunneling. The best repair method depends on where the leak is and the condition of your plumbing.

How much does slab leak repair cost in Allen?

The cost depends on where the leak is and how we repair it. After we find the leak, we’ll give you a clear estimate before we start any work.
