TESTIMONIAL

See What Your Neighbors Are Saying

From the beginning to the end of this project, the Customer Care team was top-notch. They easily accommodated my difficult schedule, the requirements of the historical building I live in, and were super responsive to all my questions. The installation team was flawless. They worked around hurdles they uncovered mid install efficiently and treated my home with great care and respect. When they left, there was not one speck of debris and I had beautiful new windows. and I could not be happier with the end product.

I’m extremely pleased with Signature Windows. From start to finish the whole process has been wonderful. After the windows were shipped they were installed in less than a week (about 20 windows). The crew, Raymond and Walter (and Eric one of the days) was amazing. They were neat, courteous and left everything in perfect order upon leaving each day. They told me to call if I had any questions. It was a pleasure to work with Danny, Sebastian and Jeff. Danny was the main person I had contact with. He was very kind, professional, helpful and he guided me through each step making it a pleasant experience. I would definitely recommend them.

Working with Signature was a pleasure. The design and product selection process was collaborative and thoughtful. The communication from start to finish was excellent. The installation crew was friendly, efficient, and skilled. We replaced a very old and very oddly installed back door on our house, and the crew put in the extra effort and time to figure out a solution that ensured the new door was installed properly and looked great. We also replaced several windows, and that work was done quickly but also with respect toward our house. I’d highly recommend using Signature for a project, and we’ll likely be calling them again in the near future to replace our front door.
