"Great company. Highly recommended. They install 2 windows for my house. Clean and neat. Price is right. Great looking windows. One stop shop."

"I'm so happy with my new windows! My only regret is that I don't have more windows to replace! Aaron and his team were a dream to work with - communicative, friendly, and direct. They worked with me to scope out exactly what I wanted and they were very transparent and fair on price. The installation team was efficient and respectful, making sure everything was done to the utmost standards. My windows look amazing but more importantly they work fantastically! I was shocked at how much quieter and cooler my house was after the new windows were installed, and they are so much easier to keep clean. I will be recommending Thermo-Seal to everyone!!"

"Lang Co Construction is the best! We love our beautiful three-season room! In the past they have also finished our basement and added a porch to our home. The work is professional and fairly priced. I would recommend Lang Co Construction for any home repair and remodeling work."

"I was extremely happy with this company. I liked the fact that he would come to install one door. (Good to his advertisement, he goes to Suffolk county) It turned out to be more than the one door.. He returned my call, the same day. I found Greg, a pleasure to deal with. I chose his company to call, over 3 other names I felt fortunate, it worked out so well, and I made an excellent choice. Now have the name of someone who handles all types of home repairs, that does excellent work. I was extremely impressed, that upon walking up to my door, he removed the snow, off the steps. Top notch company!"

"The windows were pricy but the quality of the windows justifies the price. The crew that installed the windows were wonderful to deal with. They cleaned up after themselves. The project manager was very understanding when I needed to change the schedule due to weather. They accommodated to my schedule changes for installation. They were very professional"

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."
