Colonial Plumbing & Heating

Efficiency was top notch, super clean during and after, extremely polite and respectful and Don, the owner was more than accommodating with scheduling. Would highly recommend!!

Don and his team are reliable and provide excellent customer service. We’ve been customers for over 12 years. They’ve helped with difficult to solve water filtration problems, helped us install a new shower and provide our annual heating and plumbing services. Thank you to Colonial Plumbing and Heating!

We have been using Don's company for over 15 years. They are the best and also the nicest people. My wife and I trust them so VERY much. Don and Sam are so knowledgeable and have responded quickly to several emergencies over the years. We feel so fortunate to have found them. One potential headache out of the way because we never have to worry about our plumbing, heating and air conditioning. I highly recommend. They are truly the best. I cannot say enough great things about them. Joseph Anderson, Merrimack, NH.

I'm in AZ. My father in law lives in Manchester. These guys picked up a new toilet from supply house install it for a very reasonable price. Then return the next week to install a thick toilet seat for FREE. Nice to hear that good service is still hear. Thanks Don. Walter S

I recently had all the plumbing in my house replaced and a new filtration system installed by Colonial, and I couldn’t be more impressed. From start to finish, the entire process was handled with professionalism and attention to detail. The team arrived on time, worked efficiently, and made sure everything was installed perfectly. They even took the time to explain how the new filtration system works and ensured I understood all the features. The quality of the water is incredible—crystal clear and so much better than before. What really stood out was their dedication to customer satisfaction. They were friendly, respectful, and left everything spotless when they finished. It’s not every day you find a company that combines excellent craftsmanship with top-notch service, but Colonial abs
