"Install crew was perfect. No dust, no mess. Complete cleanup, and a perfect airtight install. For years we have had winter management strategies. Closing off room on the north side... and running space heater in those rooms during use. After installation of the ProEdge windows these rooms are as warm as the rest of the house. AMAZING! Recent warm days prove the advantage of triple glazed low-E windows, too. Nice and cool inside. I searched for years for new windows that met MY specifications . As a career engineer I am happy to recommend ProEdge to anyone. Their attention to detail is superb."

Windows questions, answered by experts

Arched windows used to be most prevalent in more traditional home styles, like Spanish colonial and Gothic, but they are becoming increasingly popular in modern design. You’ll often find arched windows in new home builds across many styles, including farmhouse and contemporary architecture. This represents a more general trend toward more unique houses with interesting features.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

During hurricanes or other major storms, high winds can cause objects and debris to fly through the air, which can break your windows. Depending on how strong the storm is, the winds themselves may be strong enough to break your windows, too. Investing in storm windows or hurricane shutters can help protect you against potential window breakage.

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.
