Brian from Plumbing Geek came out and fixed our low flow shower pressure quickly and also gave us info with potential problems if that didn't solve the issue, along with estimates for those alternative options. We appreciate the fast response, professionalism, up front pricing/quotes, no hard sales, and for also wearing booties in our house. If we need plumbing help again, we will contact Plumbing Geek!

I hired Plumbing Geek to inspect a job that another plumber had done. Brian came out and assured me that it was a good job and that it would pass inspection. Everyone that I spoke to at this company was pleasant, and I would not hesitate to call them for any plumbing needs I have in the future.

Details: A few pipes • Hook-up appliance or fixture • House

Hey Torre, glad Brian could help you out. Please let us know if you need service in the future. Have a great day.
