FAQs: Door Installation in Massapequa

  • How long does a door installation take?

    The time required for door installation varies based on the door type and project complexity. 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.

  • What types of doors do you install?

    We install a wide range of doors, including entry doors, storm doors, sliding glass doors, and French doors. We work with trusted brands like Therma-Tru, Andersen, Pella, and Harvey, offering materials such as fiberglass, steel, wood, and vinyl to match your home’s style and needs.

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.
