When you call Slab Leak Doctor, you get reliable, rapid response from a team that treats your home like their own.

Our Services

The team at Slab Leak Doctor can handle any slab leak issue you may have, including:

Slab Leak Detection  |  Plumbing Leak Detection  |  Slab Leak Repair  |  Insurance Review

Tunnel Jobs

When we detect a slab leak, our skilled slab leak repair team uses precision tunneling methods to access the affected area beneath your foundation—especially for commercial buildings and residential properties in McKinney and the North DFW area. We handle every step of the excavation and tunnel formation process, creating safe, efficient access to the damaged pipe so we can perform repairs directly at the source—without disrupting your flooring or structure above.

Leak Detection

We provide expert slab leak detection and repair services in McKinney, using advanced tools to locate and fix leaks beneath your foundation with minimal disruption. If you’ve noticed signs like warm floors, rising water bills, or musty smells, don’t wait—contact the Slab Leak Doctor. Our licensed technicians will carefully inspect your home, identify the exact source of the leak, and recommend the most effective and long-lasting repair solutions.

Hydrostatic Testing

We perform hydrostatic testing to accurately detect hidden leaks and assess the integrity of your plumbing systems, including water lines, hot water piping, and pressure vessels. This advanced diagnostic method allows us to pinpoint leaks behind walls, under slabs, or inside your home's plumbing system, especially when hot water lines are suspected. The Slab Leak Doctor uses three proven hydrostatic testing techniques—proof testing, the water jacket method, and direct expansion—to ensure we identify the exact cause and location of your plumbing issue with precision and care.

Sewer Inspection

A sewer camera inspection is a modern diagnostic service where we insert a high-resolution camera on a flexible snake line into your sewer line to visually assess its condition. At Slab Leak Doctor, our video inspections help us quickly identify issues like tree root intrusion, cracks, blockages, corrosion, or collapsed pipes—without needing to dig. Even if your drains seem to be working fine, hidden problems could be building beneath the surface. Don’t wait for foul odors, backups, or flooding to discover there’s a problem. Our camera inspections allow us to catch small issues early, helping you avoid costly repairs and protect your home’s plumbing system.

Slab Leak Doctor Can Save You Costly Repairs

Plumbing problems can cause a lot of stress. Unsuspecting homeowners may not be aware of where a leak comes from or how far it has progressed until it is too late. If a plumbing issue such as a leak goes unchecked it can cause severe issues such as:

Water Damage

Undetected leaks can soak into your foundation, drywall, or insulation—leading to expensive water damage. Over time, this moisture can weaken your home’s structure and invite rot, corrosion, and mold growth. Repairing water damage is costly and often involves restoring multiple parts of your home.

Increased Water Bills

A hidden leak wastes gallons of water every day, driving up your monthly utility bill. That’s money literally going down the drain. Beyond the cost, water waste also has an environmental impact. Our expert leak detection services can help you stop the loss—fast.

Damaged Floors

Excess moisture beneath tile, hardwood, or laminate flooring can cause warping, staining, buckling, or even floor collapse. Floor repairs are not only expensive—they’re disruptive to your daily life. The sooner a leak is detected, the better your chances of avoiding costly and invasive floor replacement.

Mold and Mildew Growth

Lingering moisture creates the perfect environment for mold and mildew to grow—especially behind walls or under floors. Mold spores can cause serious health problems, especially for people with allergies, asthma, or other respiratory conditions. The best way to protect your family’s health is by resolving leaks quickly and completely.

How Do Slab Leaks Happen?

Slab leaks occur when water pipes beneath your home’s concrete foundation crack, corrode, or burst—often due to soil movement, pipe age, or poor installation. In areas like McKinney, TX, expansive clay soil and extreme weather make homes especially vulnerable to these hidden plumbing issues.

At Slab Leak Doctor, our licensed professionals specialize in detecting and repairing slab leaks with precision and care. We arrive on time, treat your home with respect, and use the latest tools to identify the exact source of the problem—so you can get back to normal with minimal disruption.

Common Causes of Slab Leak

Slab leaks cause unexplained increases in the water bill, reduced water pressure, and the floor develops damp spots, among others. The following are common causes of slab leakages;

Friction and Regular Wear & Tear

Over time, water and sewer lines buried beneath concrete slabs can become damaged from repeated expansion and contraction—especially when exposed to fluctuating temperatures. As the pipes move, they rub against surrounding concrete or soil, causing gradual wear and weakening. Hot water lines are particularly vulnerable, as they expand and contract more frequently, making them more prone to developing slab leaks.

Poor Quality of Water

If your home has a constant supply of highly acidic or alkaline water, it can gradually corrode your plumbing pipes from the inside out—especially copper or metal lines. To protect your system, it’s important to regularly test your water’s pH levels and watch for signs of corrosion, such as green or blue stains around sinks and fixtures. Acidic water may also produce a strong chlorine-like odor, which can signal an imbalance that should be addressed before it leads to costly plumbing damage or slab leaks.

Poor Construction

Poor construction practices—such as improperly bent or stressed water lines installed beneath your home’s slab—can lead to premature pipe failure. Over time, the constant pressure of flowing water combined with pipe misalignment can cause leaks to develop. Homes with cast iron pipes are especially at risk, as these pipes are prone to internal corrosion and erosion from abrasive water flow. If left unchecked, these slab leaks can lead to significant structural damage and may require extensive underground repairs or rerouting to resolve the issue effectively.

Shifting Soil

Underground water movement and natural soil shifting beneath your foundation can gradually cause your home to shift or settle unevenly. This movement puts stress on buried sewer lines and water pipes, often leading to cracks, joint separations, or full pipe breaks over time. If these issues go undetected, they can result in severe water damage, foundation problems, and costly plumbing repairs. Early leak detection is key to preventing long-term damage and protecting your home’s structural integrity.

First time customer. The hot water line to our washing machine broke when I tried to remove the hose from the valve. After my wife saw an online recommendation, I called and left a detailed message. They called right back within about 5 minutes. Extremely professional and friendly on the phone. They scheduled a repair right away. Gage arrived within an hour (maybe 30 minutes?). Very friendly and professional. Made a clean and fairly small exploratory cut into the drywall and found the problem right away. He made a quick trip to pick up a new valve. Responsive, courteous, professional, affordable. Thank you thank you thank you! Smith and Son were our heroes today!

We called Smith and Son Plumbing for the first time to replace a failed hot water heater. We have been dealing with two traditional tank heaters that never seem to last to their warranty. We have dealt with home warranty companies for years, but with horrible experience. Now that we can choose our own company, we are so glad to have found Smith and Son. They replaced the tanks with a tankless hot water heater and are incredibly professional. The day after the install we called back with two small concerns/questions and they came right away to address and resolve both! We will gladly use Smith and Son for all of our plumbing needs from now on!

Needed a shower faucet replaced, actually ended up needing the whole valve replaced, as the old one was damaged. Their quote was in-line with another place I had look at it. To be completely fair to them, their final project price was substantially cheaper, as they took time to explain that if I did some of the demo work myself, the final tab would be far less. I appreciated that extra dose of honesty and communication. Very punctual as well. All aspects of the interactions were greatly positive. Hoping I don't need a plumber again anytime soon, but if I do, this will be the first place I call - and recommend to others.

Smith and Son saved the day (and the long holiday weekend)! I could not be more appreciative. Yesterday evening, I had very low water pressure and I had leaking from what appeared to be the front of the house (it was the pressure relief valve). I had to turn off the water supply since it was drenching the yard. Momma ain't happy when water was not on demand. I called one company I had used in the past and they had no availability...I got concerned (again, momma ain't happy when she ain't got water/toilet/shower...and if momma ain't happy, well, you know...). Having the water turned off for the long weekend would have been a miserable endeavor. In addition, I wouldn't have a spot in my schedule next week to meet someone to have a repair done. I began to quickly read reviews for plumbers in the area and came across Smith & Son. When I called, they were super nice. They mentioned they had a full day scheduled for the crew, but the desperation in my voice must have been evident and they generously rearranged the schedule and made a spot for me. Rick came to my house on time, listened to my problem, automatically knew the solution, instantly gave me a quote, and level-set my expectations on what could pop-up once he got into it. I really appreciated his professionalism and straightforwardness. Great communication and answered all of my questions. The quote was in-line with what I expected (after trying to self-diagnose via google and research how much each scenario would be). The pressure relief valve is an outside repair requiring a lot of dirt to be dug up...and its July in Texas...needless to say, probably not the funnest repair for him before a long weekend when we all just want kick off early and have a little family leisure time. I am so ecstatic that it got done today. While my budget wasn't expecting a plumbing job, I knew the price was fair. Rick even put the flower bed back together as good as it was before the required digging. And the final price was no more than what Rick had level-set. No "gotcha's" or sneaky added in fees or charges...just paid what I had expected. I would highly recommend Smith & Son Plumbing. Not only are they now my "go to" for plumbing issues...I now have a great business to recommend to my friends when they ask me if I know of any good plumbers. It was a real blessing and a load of stress lifted. Thank you Smith & Son Plumbing!

2nd time in a month using Smith & Son services...good both times! I requested Gabriel (he is the 'Son'). Replaced the PCV outside and our water pressure increased from 40's to 80's!! Very happy to have pressure for more than one water need at the same time, and very reasonable price (I got a Senior discount, too), especially when compared to another well known plumbing company in the area.

A+ to the plumbers who actually showed up, when they said they would, and fixed my leaky hose bib. The price was reasonable, the repair was fast, and they were super friendly to boot. We have had a heck of a time getting a plumber to show up at all. We've had a couple say they would come, and then cancel last minute. One guy strung us along for a couple of weeks. Another showed up completely unprepared for a basic job after days of delay. Smith and Son kept their appointment with us and were very professional. We will be calling them first for future plumbing needs.

Fast response time, did a great job fixing my gas line, pricing was fair. They had to relight my water heater and because I had just moved into the home, I wasn’t aware we had 2 water heaters until 20 minutes after they left. I called and the sent someone right back super fast. Also - they have a great scheduling system with reminders that is helpful. I’ll definitely use them again

Recently we called Smith and Son Plumbing for our bathroom’s plumbing related issues, and they offered us the best quality solution with an affordable price. We experienced a very pleasant and friendly business interaction right from making the first service call to Jessica and then to the follow up visits by Technicians Jeremy and Chris. They thoroughly inspected all aspects of the damages and gave their skillful and professional opinion. Based on our consultation, we found that both of them have not only phenomenal professional experience and knowledge but also demonstrated an incredible understanding towards our request for tailoring and customizing the project. We would definitely rate this business above and beyond and recommend it to every consumer.

I am very please with the work Jeremy Williams and his coworkers from Smith and Son Plumbing did for us. It was our first time using this company, which I decided to use based on the good reviews I read and their BBB rating. So please that they live up to their word. They give a free estimate and their pricing is reasonable. They changed out my hot water heater and fixed a leak in one of our bathrooms. They replaced the two handle faucet with a new one handle and am so happy with it. From the start they were polite and friendly and even wore masks at my request because of my illness. These guys even clean up after themselves. Will definitely use them in the future if needed and will highly recommend to everyone.
