"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."

Customers say: Quick response

"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

Windows questions, answered by experts

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report. 

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.
