Thermo-Bilt Reviews

We purchased 10 energy efficient thermal pane windows and two doors in March. The representative Mr. Barry Liburkin did a fantastic job explaining the benefits of his products. We were very happy with the installation team led by Stan and Igor. The office staff was also very friendly and we will gladly refer this company to everyone for their windows and doors needs. A job well done! Thank you.

Fantastic windows and installation services! Staff were prompt, courteous, and skilled. These windows are definitely high quality but the costs were affordable. Make a point of calling this excellent company.

We are very pleased with this company. They replaced 8 Windows in our house. Peter and his crew did a masterful job on our Bow window build. The job was done fast and efficient and we love the high quality of the product.
