Customer Feedback

The windows are great.  We had 21 of them installed and they have helped in heating and cooling savings since.  Thanks for a good product.

I found Custom Built Window in Rhode Island with Google’s help, and was immediately impressed with them. I told them what we needed, we communicated a couple of times via email, talked once on the phone, and bang, we had our window within 10 days from submission of the order. And it’s perfect, exactly what we wanted. Very well made too.

I have been buying Custom Built Window & Doors products for about 20 years. Their quality and service is second to none. I would recommend them to anyone. They always stand behind their product.
