Comments: These guys are good. They gave us a reasonable price, came out on time, and installed a quality water heater with a 10-year warranty. They were both friendly and knowledgeable and left no debris behind. They also took the old water heater with them and did not charge extra. It's been nearly two weeks since the installation and everything is working properly. What was not to like? --- Jim R

Comments: The work was done in a very professional and knowledgeable way. Mr Hathaway replaced our hot water heater tanks. He knew exactly what was needed. He discussed the situation over the phone with with me, and came the next day with the appropriate tanks. He and two assistants completed the job in about 1 1/2 hours. He left me with diagrams describing the installation plumbing. The price was less than other quotes I had gotten. Everything has been working perfectly. Mr Hathaway and his assistants were very pleasant and courteous. I can not imagine a better job.

Comments: Sam returned our call and came to the house when we had no heat on a Saturday. He was able to give us a temporary fix and didn't charge us. We ended up needing a new boiler install. Sam did a great job communicating throughout the entire process. Sam & team were able to get the job done efficiently so we were able to stay in our home during the work. We are extremely happy with the work they did & highly recommend them.

Comments: I was in a pinch today and Sam really helped me out. He replaced my water heater within a few hours and was nothing but cordial

Review Date: 02/25/2018 | Author: Alex G.

Comments: We had no heat last night. After we posted our problem on home advisor, Sam called us within 5 minutes. He came to our home on a Saturday night, after 9pm. Sam, was professional, knowledgeable and neat. Our home was a mess because of February vacation and constant renovations. Sam, made us feel at ease and got right to work. We had heat within an hour of him working on our boiler. He was even kind enough to answer our plumbing questions that had nothing to do with our current problem. His price was very reasonable and we won't hesitate to hire him again. He even followed up with us today, to make sure everything was working well. If you are looking for a personable, experienced and hardworking plumber, call SDH plumbing and Heating!

Comments: It was new years day, they responded quickly, they fixed the burst heating pipe, the work was done in about an hour and a half. All that is good. But I think their bill, $680, is a bit steep. On the other hand, not getting the pipe fixed would have been worse.

Review Date: 01/07/2018 | Author: Regine R.

Comments: They came on a Saturday. a heating pipe broke and with the very cold weather we were desperate. They came the same day at the time they had predicted. Looked at the system, explained the options and took their time to repair and clean up. Very courteous and professional.

Comments: We were in trouble due to severe cold and no heat. They called and told me that they will be in one hour and told me the price upfront. Came and fixed the issue. Due to the first visit, the price is little higher but it is ok, they look like experts.

Comments: S.D.H replaced my kitchen faucet. They showed up on time and did the job well. Also, the whole process was smooth in terms of communication. Also hired them to replace a disposer for my rental apartment. Everything was done well and both myself and tenant are happy with results. Will continue using S.D.H for my plumbing and heating needs in the future.

Comments: Sam was very responsive and polite. Rescheduled the appointment for an earlier day - no problem. Did a good job fixing the leak. Had to drive across town to get a part. Stalled for enough time to charge for an extra hour. I guess most of them would. Other than that no complains.
