"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 questions, answered by experts

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Yes, you can fix windows without replacing them. However, this will depend on the severity of the issue and what your needs are. Minor water damage, broken glass, damaged casing, and worn caulking are usually easy repairs. But if there is excessive damage, the windows are constantly foggy, or the windows are very old, it’s best to consider replacing them. Replacement windows cost between $575 and $1,475 per window, or an average of $850 per window. 

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.

Deciding whether to repair or replace a window depends on the specific issue, the window's age, and the cost-effectiveness of the solution.

Repair is often better for:

  • Minor issues such as a single broken glass pane, a stuck window, or small leaks. Repair is typically more affordable for isolated problems.

Replacement is the better long-term solution for:

  • Major problems like deteriorating or rotting frames, significant leaks, or drafts.

  • If your windows are over 15 years old, as repairs may only be a temporary fix for an aging unit.

  • If you have a widespread problem affecting several windows.
