"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Hired to replace 2 window screens on the second story of our home. Val found another one that needed replacing, and he did that one too, for no additional charge. He also fixed our kitchen light so that it stopped blinking when we first turned it on. Friendly, courteous, punctual and professional. Will be hiring again."

Windows FAQs, answered by experts

Picture windows are still in style, even though they are one of the oldest types of windows. Other windows, like single- or double-hung windows and casement windows, have increased in popularity because they can open up for fresh air. However, homeowners still love the way a picture window can frame their lush outdoor garden or other pleasant neighborhood views.

Glass block windows are energy-efficient because they are much thicker than traditional glass panes, making them better insulators. They are sealed airtight, which prevents drafts and stops warm or cool air from escaping, helping to save money on heating and cooling bills. Unlike traditional windows that can be opened and closed, sealed glass block windows eliminate the potential for air leaks. For proven efficiency, look for options that are Energy Star rated. The cost for energy-efficient glass block windows is typically around $400 per window, which may be higher than standard windows.

If you decide to forgo your old windows and upgrade them to modern day technology, there may be some people interested in the old windows. You can try selling them on an online marketplace for around $50 to $100 each (so long as the window wasn’t damaged during the removal). This can also help off set the overall price to replace them.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.
