"Hot water heater died on Wednesday. Thursday morning I talked with Jordan and a new one was installed at noon on Thursday. He was professional, knowledgeable and had a sense of humor. I am already looking at future work for him."

"My water heater died (leaked) late Wednesday nite. Thursday I called numerous plumbers-left messages, Burke's called back and by Friday afternoon I had a new water heater installed. I am in a mobile home and some plumbers said they don't service mobile homes."

"I am a person of modest means; because of APM I was able to replace my heating system at a price I could afford. APM helped me choose the right appliance that I then ordered online to save money. Appliance did not come with a part I needed for my specific installation; they educated me about the part, I was able to do an internet search and obtained the item on Ebay for a steal. Service quality was top notch, easy to work with, great communication via email and phone, worked clean, very nice people. I feel very fortunate to have had this service experience and would highly recommend this company.

"Called Burke and Sons to replace a ruptured how water heater, they were prompt in getting over but not much else was good. Two very young guys came over and did the work. They were not very professional but the job got done, so I didn't really care. I never really check the area where the heater is, and today I was in that closet and it's a mess. One of the vent pipes seems to have a leak and there is a bit of mold on the floor underneath the tank. The previous tanks in that spot had been there for almost 20 years with no such issues. Also, since it was urgent, no hot water, I didn't get prices which was also a mistake. My neighbor (condo complex) needed a new tank about a month later but got prices before having the work done and paid about 850.00 for the exact same setup that cost me 1150.00. I actually ran into the guy bringing his tank in and I stopped to talk to him and he was amazed at how much I paid, and asked if there was an office where he could leave his card. He figured he woud get a lot of business, being that much cheaper."

"Lavoie Plumbing & Heating installed a full house water filtration system at my residence. They were in and out by the end of the day and we had clean water by the time I got home from work. Highly recommend, you can't go wrong hiring Danny from LPH."
