Real Google reviews
Jose from GarSan Plumbing Services came out to assess and locate a water leak that had caused significant damage inside my home. He was punctual, or early, for each visit and spent the time required to assess the situation and provide cost effective solutions. I think he did a fantastic job and I would definitely call him again when I need plumbing work in the future. Thank you!
Will use for any future plumbing needs. Had a 70 ft buried gas line installed for a generator along with Riser and regulator. They showed up on time for both the estimate and the work. Finish the work in a timely manner communicated every step of the way there were no surprises. 100% recommend.
Responsive, easy to work with. Clearly explained the issues and the options. We are a small business and will definitely keep Jose on speed dial.
