Slab Leak Testing

We test sewer and portable water systems. We perform camera inspections, pressure tests, hydrostatic tests, and isolation tests. We perform plumbing inspections for new home buyers, sellers, and after recent home foundation work. 

When to get a slab leak test?

  • Sounds of running water in your walls – Do you hear water running in your walls even though all faucets and appliances are off? 
  • Increased water bill – Have you noticed a spike in your water bill?
  • Low water pressure – Have you noticed a drop in your water pressure?
  • Foundation cracks – Are you experiencing cracks in your walls or flooring?
  • Discolored wet or hot spots on your floors or walls – Have you noticed wet spots on your walls or floors?

If you’re experiencing some of these problems, you may need a slab leak test.

H&M Plumbing and Drain


Hear what our customers have to say!

They did an outstanding job! All at a fair price! It hard to find a good plumber, H&M is the best! 



Frank L. in Dallas, TX


Had a seriously clogged bathtub drain, and contacted them in the morning, and 2 hours later they were here. Great customer support, did a good job getting the drain cleaned, and feel confident our plumbing issues are permanently solved, Would definitely recommend. In case of a plumbing emergency, you should have a professional backup. I trust these guys 100% and will recommend to everyone!

We had a problem created by painters who washed plaster down our drain, it dried, and then stopped it up.  The first plumber started the job and found the plaster, then ghosted us.  H&M came out as promised, gave the worst case scenario estimate (which was lower than the lowest of the first plumber), got the utilities out to mark the lines, dug a 4ft trench, finished the job, and the total was less than the estimate.  They did the whole thing in ONE day!  Many thanks to you, Romauldo, and your helper for fixing our 2 weeks long plumbing nightmare!!
