Mastery Plumbing 7616 South Main Street, Coopersburg, PA 18036

"We had our water filtration system installed by Mastery plumbing, and wow what a difference it made for us! We had a strong chlorine taste and water stains on our fixtures, but not anymore. The folks at mastery plumbing know their stuff and do a great job! We will definitely be using and recommending them in the future!"

"Great communication and quality work, would use again. They cleared my sump outlet, installed a clean out connection, and a new pump. They also installed a water softener and RO drinking tap. What a difference! They were clean, friendly, showed up on time, and did nice, neat work."

"As always, Mastery Plumbing earned my 5-star rating! It was nice to see a familiar face (Brent) who did our work a year ago. Friendly, clean, and informative conversation make Mastery Plumbing worth the repeat business. Thank you!"

"Recently had Mastery Plumbing install a new tankless water heating system with pressure regulator valve & smart valve. The increased water pressure and water temperature is amazing. My wife and I love the added benefit of the smart valve, that if we are not home and we get an alert on the app that there is a significant change in water pressure, that we have the ability to shut off our water remotely from anywhere to avoid a possible water leak / flood in our home. Dan and his staff were friendly, professional & very knowledgeable about their products. They completed the job in the timeframe they said they would and I would highly recommend them for anyone that needs plumbing services in their home."

"Sad to say I am extremely disappointed. They damaged our new dishwasher, didn’t tell us. A huge scratch because they didn’t screw in a bolt all the way. Then they tried to make it our job to fix it and call the manufacturer ourselves. 4 months later and it’s still not fixed. Placed the tub too far away from the facet the water filled half in the tub and half out into the floor! Charged us $1250 to place our tub (too far away yes). It drained soooooooo slow and they wanted to charge us $1500 more to fix it. Forgot to put the drain pipe to our water filter into the pipe and flooded our basement TWICE! Damaged our stuff both times. Didn’t hook up the 3rd line to our washing machine and the first time we used it water leaked EVERYWHERE. Everything we purchased they didn’t know how to install but the options they provided were cheap low quality. They installed our Kraus garage disposal but it leaked immediately. They said it was the brand and would only fix if we paid $600 for the generic brand that they provided. Plus we had to eat the cost of the one they installed incorrectly. We were told there would always be a master plumber on site but an apprentice did ALL the work 95% of the time alone or with a student. Installed the pipes under the sink in a way that you couldn’t utilize the cabinet AT ALL. They fixed it but only after we asked, why it was installed that way in the first place is beyond me and I’m not a plumber. We bought Kohler bathroom fixtures from Kohler directly and they needed us to replace the diverter valve and shower head because they broke the diverter during install and honestly I think they just didn’t tighten the shower head right but it leaked so they told us it was bad. Had to have them come back out to adjust the shower knob because it was installed in a way that it couldn’t fully turn on, it was being stopped too soon. Then we had to have them out again to fix the temperature within the fixture because it wouldn’t allow it to turn on all the way hot. Charged an arm and a leg to install the toilet… within a few days it was rocking. Bolts weren’t in place. Had them come fix. It was rocking immediately after they left, I honestly don’t think they didn’t anything. Still rocks now. The list goes on. We spent (they charged us) a lot of money doing a whole house rebuild with addition. The quality of work at the end of the day was poor. We made the mistake of paying in full for the work. Would not recommend! Definitely would not recommend if you plan to buy your own stuff for them to install and their options are cheap/low quality which they charge you more than you pay for the highest end."
