“We had our garage outside door replaced and Nick did a fantastic job it looks so good. We are so happy with how everything turned out he even came out on a sat morning and was done in less then 2 hours! Definitely be using again“

“Energy swing delivered in full on every aspect of my new door installation. The quality of both the doors and the sidelights were leaps and bounds above my previous doors. The installation crew (Fred, Steve and Dale) was friendly and efficient with a flawless install. Would highly recommend for anyone looking for a high quality product with an unbeatable warranty.“

“Ray M. and Renzo M. were excellent, professional, and completed the job quicker than expected. I recommend them and West Shore to put my home’s shower in. So excited to use my new shower.“

“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.
