"We came home after a week of vacation and found that we had a hot water leak. We contacted Water Fixers and they sent out a plumber to check out the situation. After that we received a quote for the work to be done. We spoke to Lynda the Office Manager a few times and she was very kind and helpful. We also spoke to Victor, the Owner and he was very nice and professional. Victor explained to us what needed to be done to repair our slab leak. Fortunately the leak itself was small and had not done any damage so they did not have to rip up the floor. They did have to cut several holes under sinks, the hot water heater and in the ceiling in our laundry room as they had to put in new water lines and reroute them into our attic and down the walls into both bathrooms and the kitchen. We ended up having two plumbers doing the work and it took 4 days to complete the job. The two plumbers were very nice and worked very hard to get the leak repaired and made sure to verify that the repair was done correctly and that there were no leaks when they were done. The final bill was a bit more than the quote, but we believe that the charges were fair and we are satisfied with the work that they did. Water Fixers also took care of the leak detection themselves, which was really convenient so we did not have to have two different companies involved. We highly recommend Water Fixers for any plumbing job small or large."
