I had a slab leak and the recommended repair was to reroute the water line through the attic. Matthew and his assistant were very competent and professional. It took them about 5 hours, they had to verify where the leak was and then cut 3 holes in the sheet rock in the pantry and a bedroom, then run the new line. When they left, there was no mess in the bedroom, kitchen, and garage. They replaced all items they had to take out, swept and mopped the floors. I would definitely use them again.
