Sebastian came and did the initial inspection and then Kevin came 2 days later for the install to fix my shower valves. Both of them were professional, nice, and answered any extra questions I had about shower heads and filters. Will hire again!

Miguel came at 8:30am and knocked on the door, I was in a meeting and never answered but he still had the politeness to wait for 5 minutes outside. Once he saw the clogged bath he worked on it on his own and had it fixed within 15 minutes. He was able to explain to me the issue and how to prevent it in future.…
