Your home’s piping has a limited lifespan of 10-30 years. If pipes are old and not properly maintained, they become vulnerable to dangerous leak points. A slab leak is a waterline leak below the concrete foundation (or “slab”) of your home, causing thousands of dollars of water damage to your flooring, walls and piping system.

Symptoms of a Slab Leak

Signs of a slab leak can occur in subtle and obvious ways.

  • The sound of constant running water.
  • Low water pressure and abrupt increase in water bill.
  • Water coming through house foundation.
  • Wet spots, stains and cracks on walls.
  • Warped, stained or wet flooring.
  • Moldy carpets.
  • Hot spot on floors (common for radiant heating systems, where hot water leaks underneath the concrete slab).

Test for a Slab Leak

  • Check your water meter—if you notice a lot of dial movement within a few minutes, you most likely have a leak.
  • If your home uses a well, shut down the valve between your pump and pressure gauge. If the pressure gauge goes down without water being run, you probably have a leak.

If think your home may have any type of subterranean leak, contact a plumber immediately. We will work fast to find the leak source and repair your water line to prevent as much damage as possible to your home’s foundation, flooring and walls.

...This was probably the most satisfying home service experience we have ever had. We found our plumber for any plumbing needs ever, and I am quite certain that everyone will have the same reaction to this plumbing firm as I had today. Highly recommended with no reservations.

There should be a 6/5 option for going above and beyond! I have been dealing with a bathtub that would not drain no matter what I tried (plunger, 2 foot long hair snare, etc.). I called Paul on Monday, knowing that I literally have 10 people coming to visit over the weekend and was panicking about my puddle. I couldn't be home from work to meet them there/let them in. Before lunchtime, Paul had sent Danny to my workplace to pick up my house key, and an hour later, I got a text from Danny showing me what all he pulled out from the depths (nasty!) and saying it was good to go, and he left my key in the safe spot I requested on his way out. I can't believe how quick, efficient, and trustworthy they are. They are the kind of people you can trust to be in your home without supervision, and that means so much given that I work during normal contractor's "business hours". Paul and Danny are so great, and I will use them again when/if the need arises!
