Slab Leak Repair in Seattle | Slab Leak Plumber Services
Slab Leak Repair Seattle?
We'll Find It and Fix It—Fast.
Avoid costly damage to your home's foundation. Our expert plumbers use advanced tools to detect and repair slab leaks without unnecessary demolition.
What's Beneath Your Slab Could Be Costing You
Let’s be honest—most homeowners don’t think about what’s happening under their concrete slab until something goes wrong.
A slab leak is exactly what it sounds like: a pipe leak that’s happening underneath your home’s foundation. These under-slab leaks occur when water or sewer line pipes beneath your concrete slab develop cracks, holes, or complete breaks. And if you’re reading this, you probably suspect you’ve got one brewing in your home’s plumbing system.
- Warm or damp spots on your floors (especially weird when it's not near a bathroom)
- Your water bill jumped for no apparent reason—sometimes doubling overnight
- You hear running water when everything's turned off
- New cracks showing up in walls or flooring
- Soggy spots in your yard near the foundation
- Lower water pressure throughout your home
- Hot spots on tile or hardwood floors from hot water line leaks
That last one? That’s your house trying to tell you something important about potential slab foundation issues.
We’ve been doing plumbing repair work for over 15 years, and I can tell you—slab leaks don’t announce themselves with fanfare. They start small, stay hidden beneath your concrete slab, and by the time most folks notice them, they’ve been doing damage for months. Sometimes years. The soil underneath gets saturated, which can lead to foundation settling and costly repairs that go well beyond basic plumbing work.
But here’s the thing: catching these leaks early makes all the difference between a straightforward slab leak repair and a foundation nightmare that’ll have you writing checks you never planned to write. Water damage from undetected leaks can compromise your entire foundation system.
Slab Leak Repairs Are a Specialized Job —And It's What We Do Best
At Danika Plumbing, slab leak detection and leak repair is what we do. It’s not a side service we offer when we’re not busy with faucets—it’s a core part of our business. And there’s a reason Seattle homeowners keep calling us when they suspect trouble under their concrete slab foundation.
- Non-invasive electronic leak detection We don't start jackhammering your floor hoping to stumble across the problem. Our electronic listening equipment can pinpoint leaks through concrete without breaking anything. This advanced leak detection technology saves you money on unnecessary demo work and gets your plumbing repair completed faster. Pretty neat technology, actually.
- Experience with Seattle-area homes We've worked on everything from 1950s ramblers to brand-new construction with different slab foundations. Different eras, different pipe materials, different challenges with water line and sewer line systems. We've seen it all—from corroded copper pipes to failing PEX installations under concrete slabs.
- We isolate before we excavate Once we know exactly where the leak is located, we create the smallest possible access point for the repair work. No unnecessary demo work, no "well, we're already here" upselling. We understand that homeowners want their slab repair completed with minimal disruption to their daily lives and property.
Precision Leak Detection. Minimal Disruption. Permanent Slab Leak Repair.
Here’s how we handle your slab leak repair from start to finish:
- Step 1: Inspection & Listening Tools We use electronic amplification equipment to listen through your concrete slab for leak sounds. It's surprisingly accurate—we can usually pinpoint a leak within a few inches using specialized leak detection equipment. No guesswork, no exploratory digging that damages your foundation or floors.
- Step 2: Confirmation & Access Plan Once we've located the leak in your plumbing system, we map out the most efficient access route for the repair work. Sometimes that's through the floor, sometimes it's better to go around the foundation perimeter. We always choose the path that minimizes disruption to your home while ensuring proper access to the damaged pipes.
- Step 3: Leak Repair Options Depending on what we find in your slab plumbing, we've got three main approaches for repairs:
- Spot repair: Fix the specific leak location and get your water service back to normal
- Pipe rerouting: Run new pipes along a different path through or around your foundation (great for older pipes that might develop more leaks)
- Pipe lining: Insert a new pipe inside the old one using trenchless technology (when the conditions are right for this repair method)
-
Step 4: Site Restoration We clean up, patch whatever concrete slab area we opened, and leave your home looking like we were never there. Well, except for the part where your slab leak is actually fixed and your water pressure is restored throughout your plumbing system.
One thing I've learned over the years—homeowners appreciate knowing what to expect during slab leak repair work. No surprises, no "oh by the way" moments halfway through the job. We explain each step of the repair process and keep you informed about the cost and timeline.
Clear Leak Repair Pricing. No Upsells. Just Solutions.
Let’s talk money. Because I know that’s what you’re wondering about when it comes to slab leak repair costs.
Slab leak repair costs depend on a few factors: where the leak is located in your foundation, how extensive the water damage, what type of pipe materials we’re working with, and what kind of access we need to reach the problem area. But here’s what we do differently than a lot of plumbing companies when it comes to leak repair service.
Our leak detection service fee is flat-rate and gets credited toward your repair if you book the repair work with us. So you’re not paying twice for the same service—the detection cost gets rolled into your total repair bill.
We also offer financing options because, let’s face it, slab leaks don’t usually happen when it’s convenient for your budget. These repairs can range from simple pipe patching to complete line replacement, and we want to make sure cost doesn’t prevent you from getting the plumbing repair your home needs.
What we don’t do: show up, find additional “problems” with your water line or sewer system that weren’t there before, and suddenly triple your estimate. That’s not how we operate when it comes to slab repair or any other plumbing service.

You've Got Questions. We've Got Real Answers.
Not necessarily with our leak detection technology. We use precision detection to minimize the access point needed for repairs. Sometimes we can access the leak from outside your home entirely, working around your foundation rather than through your floors. When floor access is needed for the repair work, we typically open a 2×2 foot area—not half your living room.
Most slab leak repairs are completed in one day once we locate the problem. Complex pipe rerouting jobs might take two days, but you’ll have water service restored within hours of us starting the repair work. Simple repairs to copper or PEX pipes under the slab usually take 4-6 hours total.
Sometimes, depending on your policy and what caused the leak in the first place. It depends on whether the damage resulted from gradual deterioration or a sudden pipe failure. We can provide documentation for your insurance claim and work with adjusters when needed to help with your leak repair costs.
We warranty our slab leak repair work. Period. If our repair fails, we come back and make it right at no charge. Our repairs are designed to last decades, not just until your next water bill arrives.
We offer same-day service for slab leak emergencies. If you’re dealing with active flooding, foundation concerns, or complete loss of water service, we’ll prioritize your call. Most leak detection appointments can be scheduled within 24 hours.
Almost never. We can usually maintain water service to most of your home while we work on the slab repair. In rare cases involving major line replacement, you might be without water for a few hours, but we’ll coordinate with you to minimize the inconvenience.
Take Action Before the Slab Leak Gets Worse
Slab leaks don’t fix themselves. Let’s take care of your leak repair today.
Every day you wait, that leak is potentially causing more damage to your foundation, your flooring, and your peace of mind. Water from leaks can saturate the soil beneath your home, leading to foundation settling and much more expensive repairs than simple pipe fixes. I’ve seen homeowners put off slab leak repairs for months (usually hoping the problem will somehow resolve itself) only to end up with much bigger—and more expensive—foundation repair issues down the road.
The good news? You found us. We’ll handle this slab leak repair the right way, with minimal disruption to your life and maximum attention to getting your plumbing system fixed properly the first time. Our repair work is guaranteed, and we use quality materials that will last for decades in your slab foundation.
