"We have depended on Fred and Son for expert plumbing help for years now. Today it was Joe who did the installation, and we couldn't be happier with his work. Equally important, we appreciate how friendly, considerate, and professional he was throughout his visit. We will continue to have Fred and Joe on speed dial!"

"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."

"I called Remedy at 7:30am to request a new toilet installation, and they were able to get it done the same day at a very reasonable price. The technician took his shoes off before entering the house and kept his mask on the entire time. He was professional and courteous, as was the office personnel I spoke with. They removed the old toilet, installed the new toilet, processed the paperwork, and disposed of the old toilet, all in less than an hour. I would highly recommend Remedy Plumbing and will certainly use them again if needed."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"Terrific response timing and super friendly. Had to use them on two separate issues with ten days each time they sent a knowledgeable, competent, plumber who made the repair (installing new water line shut offs as well as a new hot water heater) within hours. Highly recommend Mr. Rooter"

"We had been having an ongoing leak coming through our ceiling that noone could seem to fix or truly take the time to locate and fix the problem but when Homeserve finally sent this plumbing company out it was a totally different experience, Connor and the other young man called ahead, arrived promptly and did a thorough job! They found the problem, fixed it, even repaired some unfinished issues the previous plumber left behind and thoroughly cleaned up behind themselves. They were professional and polite and I have nothing but positive to say about this company."

"No respond to warranty questions. Paid for system checks which they tried to sale enhancements. So much for the idea of finding problems before they occur by doing two checkups each year. I discover all of the problems after the checkups were done that require one or several call backs. Not sure how they classify techs as seniors their licenses are journeyman."
