"In July 2005, Bowers installed new awnings over my rear patio and 3 windows plus later installed a special awning treatment for my swing set. It will be 14 years in July, the patio awning still looks great. I highly recommend this company for their service and cost effective pricing. Don H., Palmyra, PA"

Window Treatments FAQs, answered by experts

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.

On average, hurricane windows last between 20 and 30 years. But some windows only last 10 years, while others can last 50 years or longer. Vinyl hurricane windows have a shorter lifespan than aluminum, so invest in high-quality hurricane windows and properly maintain them to get the most out of your investment. 

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.

A garden window is about 16 inches to 24 inches deep. This extra space makes room for small potted plants, which is how the garden window, also called a greenhouse window, got its name. Because garden windows jut outward from the house, they need to be installed in a place where they won’t obstruct walkways.
