"I woke up Monday morning to an icy shower and realized the water heater was on the fritz - not a great way to start a Monday! I called and left Doug a message - he called me back within 10 minutes. He gave me a verbal estimate on the phone, met me at home after work on Monday, and I had a new water heater first thing Tuesday morning. No muss, no fuss! Everything was cleaned up and Doug accepted the coupon that was on Angie's List. I would absolutely call him again and recommend him highly!"

"Jake arrived on time and got right to work. Replaced a leaking cheap brand of water heater with a top of the line professional model water heater. Also did a great job of soldering all connections instead of relying on cheap, leaky press- on fittings. Looked great afterwards. Price was very reasonable too. Will definitely use for future projects. Thanks!"

"I am completely satisfied with Becks. Every encounter from initial txt msg through phone call, scheduling, meeting the technicians, and their work in assessing and completing the repair was exemplary. My job was done in a timely manner which was a relief as another company quoted me a 4 day delay. My water was off at the main so I really didn't want to wait that long. The technicians were knowledgeable and professional and answered my questions. They left no mess behind. I have some future upgrades in the planning stage and will definitely consult with them at that time due to the experience I had today. So, in short, my water is back on. My leak is gone. The technicians were wonderful. I recommend Becks without reservation"

"I have a 101 y/o commercial building with the old boiler. Mark is the only plumber who I found that could service it. He knew what he was doing. Even when that horrible snow hit. His son came out diagnosed the pump. Replaced and serviced the radiators. Thank you"

"It went great.  The young man came in and went right to work.  I bought the house a year prior and apparently this has not been done on this heating system probably since it was installed.  The technician showed me before he started and after and it has been running much better.

"I called Weatherking after we identified several issues with the HVAC systems when we did the home inspection. They were able to come out in a reasonable amount of time to perform the furnace tune up and to estimate our repair costs. The tech was very friendly and gave us a fair quote. We were able to quickly get a service call to repair everything that was on our list. That tech arrived on time and worked the entire day to fix everything. He was nice and respectful of our home. Everything was repaired to our satisfaction.
