“We purchased a new exterior front door and storm door. The doors are top quality and beautiful. The sales, measuring and installation were also top quality. The installers, Tony and Dale, were very professional and courteous. Everything was explained about the doors. Perfect cleanup. Could not have asked for a better experience. Thank you Energy Swing. Tim and Barb Fisher“

“I needed two back doors replaced. I was very pleased with Brian, the salesperson that took the time to make sure I got the correct color on my doors and answered all my questions.
The installation by the team including James P., Jake H., and Simon C. were professional, meticulous, and very neat. Everything was cleaned up without any messes left behind. I am pretty fussy and couldn't have been happier with the job.
Thank you and I look forward to having more work done in the near future.“

“I replaced all 20 windows in my house. My experience with Thermo-Twin was outstanding. The salesperson was helpful in selecting the exterior and interior colors for our new windows. We opted for a full install which meant we not only bought new windows but replaced the interior molding and sills. The match to the baseboard molding is perfect.

The gentleman who did the final measurements was polite and courteous and the windows fit well so he obviously did a good job.

The installers were prompt, on time and finished the job in three days which is what I was told it would take. They were very respectful of the property, inside and out. They put down mats and plastic sheeting throughout the house to protect the carpeting and hardwood floors. Even though two of the days were very cold, in the 20s with wind, they were very efficient in removing the old windows and getting the new ones installed so I did not lose a lot of heat from the house.

We love the new windows. They slide up and down easily (double hung) and are easy to clean, inside and out. The craftsmanship on the new molding is impressive. The miter joints are perfect. We have received comments from visitors about how nice the windows look.

A couple reasons I chose Thermo-Twin. First, the windows are locally made and the installers are employees. If I have any problems with the windows, whether it be manufacturing defects or installation, I contact them. I do not have to worry about the manufacturer saying they were installed incorrectly or the installer saying the windows are defective due to manufacturing. Second, I windows come with a lifetime warranty that, if I sell the house, is transferable to the next owner.

My experience has been great throughout the process: sales meeting, installation and Thermo-Twin follow up to ensure I was satisfied. Most of all, we love the finished product.

“I have a grandfather clock (from the "80") that fell and broke 2 curve, 1 front, & a base glass. This is something that was very sentimental for me. There are a lot of adjectives to explain the service they provided such as neat, professionalism, passionate, thorough, perfectionate, timely, responsible and reasonably priced, If it wasn't for them, it would be in the scrap yard. I would have been very heartbroken if I could not hear the chimes of the clock and to see its beautiful features.“

“Willis remodeled our bathroom to a wet bathroom to accomodate my husband's medical condition. The end product is simply beautiful and exceeded our expectations.. Willis is the most professional, respectful and competent contractor we ever met. He is experienced in multiple trades, plumbing, electric etc. and has a great eye for color and design. His work exceeds 5 stars and I highly recommend him and the company to anyone. Most of all, he is a wonderful man.“
