"I have used this company for years. They are very professional, friendly and responsive."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"Our water heater died, and was leaking. We called after hours, and owner answered the phone. Technician came out next day, and he showed up on time and replaced the heater. Plumber was very courteous, professional, and helpful with advice. No complaints - work is guaranteed. Only downside: price for the water heater itself was high - could have bought comparable unit much cheaper at HD or Sears, but would then have needed to have it delivered and installed by the plumber anyway. Their work is was very good, which was most important and we would definitely use them again."

"We purchased a house and adding a whole house water filter was on our list. Our local Orbit dealer performed a free water test and confirmed a that a lot of the junk we had read was in our city water was in fact there. Our previous house also had hard water and we saw firsthand what it did to our pipes and hot water tank. Plus we were tired of a filtered water pitcher taking up space in our refrigerator. Our sales person went over all of the features of the Puronics 7000 system and outlined the maintenance which simple and easy to understand. Installation took place about two weeks later and the guys were done in a day. About a year out and we're still very happy with the improved water quality and the system itself works great."

"Very well. He does very fine work. I just called for another toilet install. He is such a gentleman trustworthy and honest. Jan Ferguson"

"Response was immediate. In spite of the pandemic, service was fast, with Mr. Feaga initially trying to help me troubleshoot the issue with the hot water heater over the phone, then coming the next afternoon. He also took the time to look at other concerns while already at the home. Very honest. Would use his services again. Refreshing to find a plumber like him."
