"I love my new Windows! Gary, window consultant gave a great in home consultation, did demos with actual windows and answered all questions and was thorough. Months later windows are finally installed and they are beautiful and changed the look of my entire house. I highly recommend Brothers if you need new windows and I’m so glad I found them in the Angi app. I had a number of different sub contractors in my house through Lowe’s and other companies I found through google that were quoting me insanely high prices after walking through my house , spending 3 minutes before they gave me my insane estimate. Brothers does windows only, has been in business for 30 years (my window installer, Wes has been with the company for 25 years, so that speaks volumes) so they know what they’re doing and got the windows installed so quickly, they were done in a day. If I ever need new windows again, I’d go with them again and will recommend to any friends and neighbors as well."

"Great experience getting windows installed by American Home Renewal. First contact was 6 months ago. I slept on it for a few months and got some other quotes. Chris was friendly as a sales man, Gave me a competitive price and some pointers on fiberglass vs vinyl. I went with Vinyl. Alex was the installer and was very detailed in explaining the install process. He explained everything in detail to me and showed me tips on how to do a proper install. We did a mix of new construction and retrofit. we added window casings and he was very thorough and asked multiple questions on how I wanted the casings to look. only hiccup was one of the windows was ordered wrong. we couldn't determine where the mixup occurred but they immediately took full ownership and reordered me a new window to the specs I wanted. I would highly recommend."

"Before setting in my window, James allowed me to paint the 3 support posts which would have looked horrible if they weren’t painted. Victor did a really nice job of putting in the garden window panes and reinserting the rubber sealing strips."

"What a great job Duck Solutions did! We were so happy with our carpet cleaning. The cleaner was quick and very good with taking out both the heavy traffic area and pet stains in our hallway and stairs. Highly recommend and will call them again soon for the other rooms."

"Great experience. Found AMG doors and windows online and they reached out and were able to clearly and professionally explain the step by step process of measuring the door ordering and the installation process. They were hassle free and was able to give me and over the phone quote for my new French doors. The install only took them 4 hours and they keep the space clean and were very professional."

"Excellent! They did such a great job and at an outstanding price. I have so many windows in my house and they came in way below any other competitor. It's been a few years but the windows still look and work great! As a matter of fact, my next door neighbor recently hired them to replace all of their windows based on the job they did at my house."

Windows questions, answered by experts

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.

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.

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Window replacement is typically always worth the cost, both from a money-saving standpoint and a comfort standpoint. If your windows are older and significantly damaged, a window replacement can actually save you money in the long term by improving energy efficiency. If your windows aren’t up to code, you may not really have a choice.
