Frequently Asked Questions

The Nature of Slab Leaks
What Are Some Slab Leak Warning Signs?

The Nature of Slab Leaks

Slab leaks begin underneath the concrete floor of your home foundation. This piece of concrete is often called a “slab” which is where the name comes from. The leak begins under the foundation of your home and it usually goes undetected until there are signs that point to it as a culprit. If they are smaller, slab leaks may go on for some time before you become aware.

What Are Some Slab Leak Warning Signs?

Since you can’t see a slab leak when it happens, you’ll have to wait for other signs to tell you what has happened. These may include mold patches around your basement, damp or soggy earth on your property, damp or saturated walls, floors or carpet and elevated water bills. The key thing to remember is that moisture of any kind doesn’t belong in your basement, so if you ever see any, you should contact a plumber as soon as possible, because you really have no idea how long it’s been going on.

Super Techs have the skills and experience to help you detect foundation leaks as soon as possible. If you suspect a leak, give us a call and ask about our slab leak detection services.

When your plumbing repairs can’t wait, call Super Techs for emergency service!

What Kind of Damage Can a Slab Leak Cause?

Most homeowners are afraid of mold when it comes to basement moisture, and for good reason. A moldy basement can pose a serious health risk to everyone in your household. Aside from that, serious water damage to your floors and walls, damaged electrical circuits and lighting, rotted wood and saturated earth are all possible consequences of a foundation leak. The fact that it can carry on for so long means the damage can be quite serious, and that a quick call for help when you notice a sign is imperative.

Since slab leaks are unseen until there has been some degree of water damage, it is important to take action as soon as you notice any of the signs. When you call 206.792.7495 in the Seattle, WA area, Gene Johnson Heating, Cooling, Plumbing and Electrical will send a licensed plumber to take care of the problem right away.

What Our Clients Say

Gene Johnson plumbing installed a new toilet for us, it was great working with them! Ishmael gave us estimates for various options, and we decided to buy our own toilet and have them come back to do the installation. Krystal did the install, and she was clean, efficient, very pleasant to work with, and the job was done quickly! It was also easy to schedule the work to be done. I would definitely work with them again!

– Lisa Henry

Another exceptional service call!…Alex was a true expert and he was very thorough and was patient while we went through our list of plumbing goals during this thorough full house inspection. He was able to give us some cost estimates on the spot. I certainly feel like I’m in the best hands and look forward to moving forward with our project.

– Ivan Archer

I had a new water heater installed with Gene Johnson this week and I was very happy with the whole experience. Eric Sams was my technician and he was incredibly knowledgeable and friendly and really took the time to explain my options to me. We have “unique” water heater systems in my place and he really knew what he was doing, I knew I could trust him. The installation was scheduled quickly and works/looks great!

– Ashley Curtin

Great experience with Branson! Very friendly, knowledgeable, and the quote was accurate. Needed shut-off valves installed on my house from the 40s, existing lines were galvanized steel, so that made things tricky. He outlined several options and recommendations, and we settled on something that will be compatible and easy to work with for future kitchen remodel plans. Will definitely be calling Gene Johnson again when it’s time to do more plumbing work!

– Brian Munn

I reached out to Gene Johnson regarding my radiant heating not working properly. They were able to come by within the next day to take a look. Tech Mike F was very knowledgeable and honest regarding next steps and questions my wife and I had. We proceeded to replace the Manifold and add a magnetic separator to my unit. Heat is now working! :)

– Phil Maaa

Prompt, informative, professional, friendly – very happy with service today.

– Francy M

Carlos was terrific!  He had the necessary parts on hand – he explained the problem, the solution, cleaned up after himself and now I don’t have water dripping under the sink!  Thank you Carlos!
