I've had a basement drain issue for about 3 years; every 3-4 months I had to call a plumber to come…read morein and snake it out. The expenses kept adding up and the issue would be solved for about 3 months then it would happen again. Not once in those 3 years did any of the other plumbers actually explain the issue or offer tips to take care of the issue; Sentry Plumbing did. I contacted them through an email late at night; early next morning they had responded and we booked an appointment for a couple of hours later. They showed up when they were scheduled, stated up front what the cost was going to be so there would be no surprise at the end, ran a camera down the underground pipe, saw the issue, explained the issue, took care of the issue, and provided tips for me in order to not have to call another plumber in 3 months. Sentry Plumbing is now my GO TO plumbing company for any future plumbing needs I may have. Extremely professional and friendly, completely knowledgeable, and extraordinarily helpful. They noticed an issue with my bathroom toilet as well and asked if I wanted them to fix it, no extra charge (other than the price of the part which was minimal). Plumbing issues are not cheap but Sentry Plumbing charged less than any of the other plumbing companies I've called for this issue and did NOT receive the helpful feedback that I did from Sentry Plumbing. 5 out of 5 stars ALL THE WAY AROUND. I strongly encourage people to contact Sentry Plumbing for any plumbing issues.

We were listing our home for sale much sooner than anticipated." I received a call Monday morning saying they received my message and they could schedule us that day as they had just had a cancellation that was actually for our area. By 11:00 Am that day the service person, TJ came out and cleaned the AC compressor and gas insert and glass. I was thrilled when I saw how fabulous the fireplace looked. Thank you Colony Heating and Ac and Thank you TJ!

2 years ago in the winter, I awoke to a cold house. I was new to the city, so I called around…read more Colony was the first available. The technician was efficient and the price reasonable. However, due to it being a Saturday, I was charged a $250 weekend service charge. The problem was that drifting snow had blocked the outflow pipe. While the technician was at my home, he received a call from my neighbor experiencing exactly the same thing. The technician advised him to clear his exhaust pipe. No charge. I did not object to the technician's service fee, but felt the weekend fee excessive, especially since my neighbor was treated fairly at NO CHARGE. Colony profited unreasonably and lost my business because of it. Dr. Sisson
