I called 2 companies based on reviews and unfortunately the other company called back 1st. Said they couldn’t fix unless they replaced entire shower faucet valve by cutting through adjacent wall. Estimate was over $1100.Reconnected with 2nd company: CW Cummings and they responded that same day. Chris was great on the phone. Ken responded knew what to do right away, had to replace handle due to corrosion along with cartridge (we did both showers) Faucet works better than ever with great pressure. Paid just over 25% of the 1st company’s estimate. What’s better, no hole in the wall.I highly recommend CW Cummings Plumbing. Professional, friendly, knowledgeable, timely, and value. Chris and Ken were great!
