"Complete main water replacement on a townhouse. Geary Powell was very accessible and clear on what the work entailed. Work quality and repair team were great. Not sure about the price didn't get additional estimates. Based on HomeAdvisor price range for main replacement the cost was midway between avg high $2500 & above avg, high of $5000."

"Kap from Joseph Plumbing and Drain was great. I requested a quote Saturday morning and they came out within a few hours. We scheduled the work for Friday and they arrived on time, were friendly and professional, and did excellent work installing my new main water shut-off valve. Highly recommend."

"Rema was fantastic. It was a tricky job replacing a water heater tank in a cramped space, and Rema both helped guide us to the right approach plus handled the install and removal of the old unit flawlessly. We'll hire Remedy again for future projects!"

"Called the main number and the lady I spoke with was very pleasant and easy to work with. Was looking to have a 50 gallon hot water heater installed, 2 drains snaked and a new faucet installed. She booked my appt for the next day. Zam came to the house to provide us the quote and even offered to do half the job then and come back in a few days to do the hot water heater. He was incredibly professional and did a great job on all the work. I highly recommend them and will call them again."

"The job was completed within the scheduled time frame. Sewer was replaced in a professional manner and passed inspection. Yard was landscaped to near previous condition. Company was responsive and courteous. I recommend P&C Plumbing to anyone who needs a sewer service at a reasonable price."

"Service was timely, friendly and efficient. The problem was identified very quickly and the serviceman had all tools and supplies on hand to complete the repair. He also tightened another fixture that was dripping but not broken and gave helpful advice about plumbing maintenance and repairs. He was also able to install a new kitchen faucet - not part of the initial order - saving me a second appointment and preempting an imminent leak and equipment failure."
