Get matched with top water main install, replace or repairers in Newtown Square, PA

"Very professional and replaced my hot water heater and installed a new toilet in about 2 1/2 hours Highly recommend!"

"Bought the water heater at Home Depot ( for 430.00) and brought it home myself. The tech came and installed it in less than 3 hours. They charged me thousand dollars. Oh, by the way... that was NOT an emergency, just a routine tank replacement scheduled several days in advance. Makes you rethink the value of the dollar."

"The workmanship was very professional and cleaned up afterwards. Wouldn't even know they were here. Billy did an excellent job with the removal and instillation of a new hot water heater. Brought the instillation up to code by adding a drip pan and expansion tank. I have them coming back to replace valves for washing machine and installing shutoff valves."

"My initial contact with Mattioni was to simply schedule a winter check-up on the furnace in our new house. I knew the furnace, a/c, and water heater were all about 11 years old and could be in need of replacement. One month later, I’ve had Mattioni replace all three and also perform some smaller plumbing jobs after the annual healthy home plumbing inspection they offer as part of their contract program (which came free for one year after I had the furnace and a/c installed). They’ve done too much work for me to go into detail on every aspect of every job they did, but, on the whole I have been very impressed with Mattioni. Their customer service, quality, and attention to detail seems top notch. If you’re just comparing prices, they’re probably not the cheapest contractor to use, but if you factor in the quality of the service they’re providing, I think their prices are very good, which is why I rated them A in this regard. As with any big jobs like installing a furnace or water heater, small hiccups can occur - in fact, a week after the furnace was installed and I had the plumbing inspection, a small gas leak was detected. After the hot water heater was installed, one of the fittings in the pipe that leads into the water heater leaked a small amount of water and set off the alarm they installed. In my view, small hiccups like this are to be expected when new installations occur. Where Mattioni really shined was in their response to these problems. In particular, I would recognize Jared C., the plumber who did most of our plumbing work. He noticed the small gas leak and had one of the HVAC techs sent out within several hours to address it. He also returned the late the same day he had installed the hot water heater to correct the small leak that had resulted from a defective fitting. I found his attention to detail and willingness to help my wife troubleshoot over the phone and then return late after a long day and fix the small problem to be exemplary customer service. On the whole, I highly recommend Mattioni. If you’re just interested in finding the contractor with the lowest price, Mattioni is probably not going to be your preferred contractor (although they were willing to match lower quotes I received on the hot water heater install). If you’re looking for an HVAC or plumbing company that has responsive and friendly customer service, technicians that pay attention to detail and treat your house as your own, and will ensure that the job is done both correctly and with a high degree of quality, Mattioni seems to be one of the best I’ve used in my years as a homeowner. They will certainly be my go-to plumber and HVAC company for the foreseeable future."

"Jennifer was pleasant and flexible with scheduling my appointment. She told me exactly what I should expect as far as cost and future communications. I loved the text message with the pic and profile of the technician. Great idea! Steve was wonderful! He took the time to explain what needed to be done and the cost before he did any work. He was extremely knowledgeable and professional and answered all my questions. I was so confident in his abilities. that I asked him to replace a pressure regulator that I had on my to do list. Again, he took the time to explain why it needed to be replaced and the pressure difference after it was installed. Overall, I was very impressed with Steve and Valdel Plumbing. I would highly recommend them, and will call them for any future repairs. Thank you! Your efforts are much appreciated!"

"They were very professional and replaced the faucet in time."

"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

"Fast and fairly priced. Colin is a knowledgeable and thorough installer."

"Our full view storm door needed the door handles replaced. We were unable to lock it. We put in a request thru Angi and Delmar Yellock of Designing Xpressions was the first contractor to respond. After discussion, he agreed to stop by the very next day. Upon arrival and after examining the door he found I had purchased the wrong parts. He fully explained what needed to be done and why it needed to be done. He visited a local store and purchased the correct parts. Despite spending twice as much time doing the repair he stuck with the original price quoted. I learned Del is actually a general contractor and does remodels and virtually any job inside the house. We will definitely be calling him back for future work. One last point: Del's price (including parts) was one sixth of prices quoted by others. This experiece almost makes me want to see something else need fixing! Great honest contractor!!!"
