Thermo-Bilt Windows and doors was highly recommended to us by a friend of ours. And so my partner and I trusted the judgement of our friend. And we we're very happy and much contented when choosing Thermo-Bilt. Danny, the sales representative that was assigned to us was very straight forward and we liked his honesty and very much appreciated it. Danny made sure that our expectation would be set before agreeing with the installation. That's one of the main reasons why we trust and like Thermo-Bilt. As for the product, service and installers, they were very punctual when it comes to time. The installer(s) were very clean and courteous and even though they needed to cut a whole in one of our the walls.. there were no traces or marks that was left on the wall. I was very surprised and very satisfied with their neatness and courtesy. Now, we are also recommending Thermo-BIlt to our family and friends. Thank you Thermo-Bilt for your business. More Power!
