How Do I Know If I Have a Slab Leak?

Think your property might have a slab leak? It’s a scary thought, but you’re not alone—many Federal Way homeowners deal with this hidden issue at some point. A slab leak happens when pipes underneath your home’s foundation start leaking, and because you can’t see them, the damage can sneak up on you. At 2 Sons Plumbing Federal Way, we’ve helped families spot the signs early and avoid major repairs down the road. With alertness and proactive approach, you can catch the warning signs well in time.

Warning Signs of a Slab Leak in Federal Way

Most of the time, slab leaks start with small clues that are quite easy to overlook:

Your water bill suddenly climbs without explanation
A section of the floor feels damp or oddly warm
You can hear water running though all faucets are turned off

A simple test you can carry out is checking the water meter after shutting off all water in the house. If it is still moving, that’s a red flag. You could even try walking barefoot across the floor. Warm spots could mean a leaking hot water line under the slab.

These small signs can mean big trouble later, from warped flooring to mold or even foundation cracks. Prompt action can minimize the mess, stress, and expense for you.

Observe any of these clues? Call 2 Sons Plumbing Federal Way today. Let us check before it becomes serious.

When It’s Time to Call a Plumber

Checking your water meter is one thing. Repairing a slab leak is something else entirely—it’s not a DIY project. You’ll want to call a professional right away if you see:

Pools of water indoors that keep coming back
New or widening cracks in the foundation
A musty smell that lingers no matter how much you clean

Undetected and untreated slab leaks weaken your home’s structure. That’s why our team uses specialized tools like electronic sensors and thermal imaging to find the leak precisely. This allows us to fix the problem without tearing up more of your home than necessary. Faster, cleaner, and far less stressful for you.

What Slab Leak Repairs Cost in Federal Way

The cost depends on where the leak is and how severe it is, but here’s a general idea:

Leak detection: $300–$600
Repairs: $1,000–$5,000+

While those numbers might feel big, delaying repairs almost always costs more in the long run. Water can ruin floors, drywall, furniture—and even weaken the very foundation of your home. Tackling it early is the smartest, most cost-effective choice.

Call for Trusted Slab Leak Help in Federal Way

Slab leaks don’t fix themselves, and waiting only makes them worse. With years of experience, advanced technology, and a commitment to treating your home like our own, 2 Sons Plumbing Federal Way is here to give you peace of mind.

Call us today at (206) 487-1757 to schedule your slab leak inspection. We’ll explain what’s happening in plain language, outline your options clearly, and get the job done right the first time—so you can get back to enjoying your home without worry.

Dave and David came and cleared out a huge clog in my kitchen sink (both sides) that has been plaguing us for a while as well a ton of glass shards that got into the drain when our glass fridge shelf broke. Dave walked us through each step of the process and explained everything which was excellent. He also gave us advice about galvanized piping replacement. They even gave us a few free parts for the sink drain that had eroded away and didn’t charge extra for it!! All around 5 star service!!!

Fantastic service and communication. Local company. Solved my clogged basement laundry utility sink. Dave and David were courteous, informative, professional and easy to engage with. Scheduling was easy (they came the next day) and they arrived within the expected time window. Transparent pricing and i could also apply a coupon. I will use them again.

Great service and Dave their plumber is the best. We have an odd house with even odder plumbing. The pipes are a mess of grandfathered-in open air nonsense, when our pump started making some noises (and a little leaking) after some DIY heat tape adventures (getting ready for colder weather), we were worried that we would need a massive repair but Dave came and looked at it and immediately realized we had unplugged the float plug from the pump plug which was 90% of the problem and the leak just need a little tightening of a flex joint. The company was quick and didn't charge for an estimate or in this case a quick "thats not plugged in right". The experience and the overall professionalism has convinced me that when I do finally need that big repair job, I'll call these guys.

Booking an appointment was extremely easy, and we were able to get one just the next day. Communication was excellent with timely reminders and a call before our appointment. Kerry did a fantastic job both advising us and effectively resolving our issue.

I have all good things to say about 2 Sons Plumbing. My first experience was a few years ago and the whole process went very smoothly. Making the appointment was easy and quick, the repair was done with no problem and I thought the price was fair. Recently, Dave from 2 Sons came out to look at several plumbing problems I was having and, within a matter of minutes, all of the problems were diagnosed. Dave gave me options and estimates all before he left my house. I haven’t had the work done yet but appreciate the information and the prices seemed fair to me. Dave was on time, professional and very knowledgeable. 2 Sons are my go to Plumbers.

Bob at 2 Sons Plumbing was amazing! We had a horribly backed up kitchen sink drain and he was able to fix it, and save us some money in the process! He heard what we had to say about our issue and double checked everything. Super friendly and very helpful. Thank you for the amazing work Bob!

Stellar job by Carey and his team at 2sons today. I had a complex job -- installing a yard hydrant/faucet for a garden across the (private) street. They had to go into the floor of the garage, run piping under the floor, out of the house, across the road. Had to cut into the asphalt, trench down a couple feet, then patch it all up again, including fixing the garage concrete floor. Super job. Looks really clean. Got it all done in a day.

A wonderful experience every time with 2 Sons plumbing. Jake and Angelo helped us with our plumbing issue. They showed up on time and gave a very reasonable estimate for the repair. We ended up replacing a couple of toilets and a part of a sink drain. They came back the next day to complete the work due to our schedule. Excellent communication, prompt, and hard working! Thank you so much Jake and Angelo!! We are very happy with 2 Sons and have used them multiple times.

Brandon and Ethan were awesome. I had a basic plumbing issue that I was too scared to address myself. They were very non judgmental and provided excellent customer service. I totally recommend 2 Sons Plumbing.
