FAQs: Door Installation in Garden City

A standard replacement may be completed in just a few hours, while more customized installations—such as French doors or entry doors with sidelights—can take longer. Thermo-Seal’s team will give you a clear timeline during your free in-home consultation.
Can you install a new door in an existing frame?
Yes, in many cases, Thermo-Seal can install a new door into your existing frame, depending on its condition and size compatibility. However, for optimal results, especially in older homes, we often recommend replacing both the door and frame to improve energy efficiency, fit, and security.

CLIENT REVIEWS
What Our Clients Are Saying About Us
Thermo-seal Windows provides exceptional customer service alongside high-quality products. Recently, I had the majority of my home's windows replaced by Aaron's team, and their performance was nothing short of impressive. They arrived on time, maintained a tidy work area, and dedicated themselves to ensuring a perfect installation of the windows.
Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
