Awning Windows

Awning windows are characterized by their hinged top, wide base, and crank-style handle. These windows improve airflow by creating a weatherproof hood when open. Best located above the kitchen sink.

Bay & Bow Windows

Bay and bow windows are projection windows that add dimension to any room. Each window has a collection of window panels. Homeowners often add shelving and a bench to optimize space.

Casement Windows

Casement windows are the most versatile and energy efficient windows from Renewal by Andersen. They’re designed with an outswing configuration and crank-style handle to secure and to ventilate any room.

Sliding Windows

These space-saving windows are ideal for small or cramped spaces that need direct airflow. Sliding windows are also called gliding windows because they open by smoothly gliding along a rail.

One of the most common window styles is the double hung window. This window is designed with two vertical sashes and a durable lock to keep your home secure. Customize the colors, handle style, and grille design to complement your unique home.

I love my new windows, made a HUGE difference in the drafts, keeping wind noise out, and keeping heat in. I also choose a different style and the view is much nicer, easier to open and close

Tonya B.

We are extremely pleased with our large dining room window. The old window was not efficient; letting cold air into the house in the winter as well letting heat from the furnace outside! The installer was very professional, efficient and cleaned everything up nicely. The entire experience from sales to installers through follow-up was a pleasure.

Seth Y.

Replaced 12 "old" draft double hung windows with new double hung windows. Remarkable improvement in maintaining and constant comfortable temperature in the rooms. Great workmen and a great finished job.
