I called him in the am, he showed up same day. Fixed a problem that was in a tight space at a difficult angle, however he did welding and the repair with minimal sheetrock destruction. He is easy to talk to and very good at what he does.

Prompt response, arrived within the timeframe, attentive to our needs, respectful of our home Walked us through the repair process and answered all questions concerning time parts, and cost before starting. Kept a work area clean, kept us abreast during the repair.
Identified an additional problem of which we were unaware. All parts needed were in his truck; no need to leave the job site.
Highly recommended

This plumber comes when he says he will. Knows what he is doing. He fixed a problem we didn't know we had. Found the actual problem. This was a pinhole in a copper pipe that would have been very hard for most to track down. He replaced the pipe and except for some holes needing patches, everything is fixed. Very nasty problem taken care of in about 4 hours. I think he charged a fair price.

We had a leak in the basement ceiling. The pipe had a crack in the elbow and was located against a board, making it difficult to access for repair.
I called PHI PLUMBING SERVICES and spoke with Don. He was out within an hour and fixed the problem.
I'm very happy with the prompt service.

Don came the next day after we call him, regarding a slow leak in the water supply line. He troubleshot quickly and identified the cause. It is a bad on/off valve to the front year lawns. He had the part and replaced the valve.
Problem solved because the water supply meter stopped rolling when all faucet in the house is Off. for a very negotiable and reasonable charge.
(Another plumbing company did no obvious troubleshooting work, and gave us estimate thousands of dollars, for a drastic measure of digging up the yard.)

Called Phi Plumbing and was the best intuition decision I've made. Kitchen sink keeps backing up due to us breaking not only 1 but 2 bits down the drain causing an obstruction blockage, had several other companies come out but problem keep occuring. Phi Plumbing were able to fix the issue by hammerdrilling the concrete and cutting about 2 feet of cast-iron pipe, flushing it out and replacing it. Thanks agian Don and Chris for your knowledgeable expertise, I highly recommend, also very good prices 👍.
