Company completed a job installing 3 Moen bathroom faucets and 2 toilet floats and pipes. The job was not done correctly. I emailed and called the company to have someone come out and fix the problems. It took over a month for them the send a technician out to fix the problems. The original cost of the job was around $500.00 dollars. I received a call one day out of the blue and asked if they could come to our house and fix the problem in 15 minutes.
They said they had no other time to do it. They sent a technician and he did an even worse job as if it was done on purpose. Very unprofessional company. I do not recommend using them for any bathroom installs. They did a fantastic job with our water heat and fixed it properly in a pinch during another service request. Highly disapointed in this company.

These guys came when everyone else was booked a week out. I had a pipe burst when we had the big snow storm recently. The ladies I can talked to over the phone were great and the plumber did his job with no issues.

Great company but prices have increased tremendously over the past few years. Average cost for cooling system on a 1200 sq ft ranch style home with an easy accessible roof ranges from $4k to $6500. We received a quote of $14k, absolutely, insane.

I've had this company come out several times to service my forced air ac/heater unit. Most recently they came out to work on a clogged bathtub line. Jeff was very courteous and helpful. He and another worker worked on my drain for a couple of hours and had everything flowing again! Great job, I highly recommend this company!

This is the second time I had a shock when I got the bill. First time, the amount doubled, was told that due to ocea regulations they needed to have two guys on the roof. Well how about inform the customer at the time of booking the appointment! Furthermore, ocea rules did not come into play last September, so not, no valid excuse! So when I gave them another chance, booked the appointment for June 2019, I was quoted an amount of $155 plus tax = $164.84!
Just got the bill in the amount was $183.99. I would not have made the appointed had I known the price, told them so at the time of booking! Several people in my neighborhood had similar experience and now using a new company with satisfactory result. I will do the same! Keep away from MJ FAHY!

Called for an appointment to have them install my mother's waterline for her new fridge, Terry came over and installed the waterline and showed her how to get the ice maker set up to produce ice. Very happy with his customer service and I will definitely give them a call again.
