What Is Window and Door Replacement?

Window and door replacement is the removal of old, drafty units and the installation of modern, energy-efficient models. At J.B.T Contracting LLC, we provide precise installation services for homeowners in Deer Park, West Islip, East Islip, and Oakdale.

A window or door is only as good as its installation. We don't just swap the unit; we inspect the rough opening for rot, insulate the gaps with expanding foam, and install proper flashing and capping. This ensures your new investment is air-tight and water-tight for years to come.

Benefits of Upgrading Windows and Doors


 

1. Lower Energy Bills

Drafty windows are a major source of heat loss. We install double or triple-pane windows with Low-E glass and Argon gas fills that keep your expensive heat inside during winter and block the sun in summer.

2. Enhanced Security

Protect your family with modern locking mechanisms. New entry doors feature reinforced strike plates and multi-point locking systems, while new windows have stronger frames and latches that are difficult to force open.

3. Noise Reduction

If you live on a busy street, new windows can make a huge difference. The multi-pane glass and tight weatherstripping on our installations significantly reduce outside traffic noise, making your home quieter and more peaceful.
