Testimonials

Mr. and Mrs D Montano

Dear George
We recently had your windows installed. I would like to take this opportunity to thank you. I can’t tell you enough how happy we are. During the selection process, your staff was very helpful and knowledgeable. They explained what types of windows and options were available. The installation service was completed to our satisfaction.
We found that dealing with Thermoline Windows was a good experience and would recommend Thermoline Windows to our family and friends.

I have been quite impressed with the product quality, service, and workmanship of Thermoline, since having all my windows replaced several years ago. The installation was super efficient and quality control was carried out throughout the process. Their service did not end with the installation. They have continued to be responsive to my various inquiries and requests. I came to know of Thermoline through a trusted source and I have continued to refer them to anyone I know that might be in need of their product and service, knowing that they will deliver with excellence. They recently completed a major window replacement project at our condominium community to our complete satisfaction.

Quality windows and great customer service. I called them for a quote on 3 windows, they accommodated an appointment at my schedule, and went through all the available options for our house and budget. The installer came and was very professional. I will definitely be calling them again for more work.
