"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."

"definitely five stars, highly recommend this people, very efficient. I contacted them and it pick me out in a few hours with the necessary thing and this is great because it shows interest about their company. They were willing to come, they went up and did the estimate. Maybe within a week the window was replaced and the door was working perfectly fine."

"Anthony knows doors, I mean he really KNOWS doors. We had two exterior doors that had been poorly installed a couple years back and had got to the point where they were almost impossible to open and close. He came out, took a quick look, perfectly diagnosed the issue(s), and got both doors working perfectly that day. We called him back a couple weeks later to install a new door on another doorway. He was in and out in a couple hours with a nice clean install. I don't know what getting the job done right is supposed to cost. There are probably lower bids out there, but to me it's worth paying to have the job done right the first time. Plus Anthony's just super nice, a great communicator, shows up exactly on time ready to work, and on and on. He's our door guy from now on."

"I contact AMG Doors through a recommendation from a friend. I contacted Michael and he was very knowledgeable about the different types of door materials and what material would work best for my area ( I get a lot of sun at my front door). Michael talked me into getting a thermatru front door and I obsoletely love it! AMG Doors already has a patio door on order for my home!"

"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."

"Ramon was right on time and happily willing to work in a drizzle while dodging a large, thorny rose-bush next to our broken window. We're very happy with the final result, and appreciate how smoothly the whole process went (at a better rate than some of the quotes we received even!) I'd definitely hire Bella's Glass again."

Window Door Contractors FAQs, answered by experts

Solar screens use a thick mesh of polyester to block out the UV waves and solar heat. While they are more expensive at about $7.50 per square foot, they can protect your porch or hardwood floors from sun damage and keep the room or porch on the other side of the patio cool.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Many kinds of window screens, such as solar screens, are designed to reduce the amount of harmful ultraviolet rays that pass through them and enter your home. The materials typically have UV-blocking properties. However, they may not completely eliminate all UV rays from passing through your home. Different window screens are designed for different purposes, and not all are designed to block or reduce UV rays. Do your research to make sure you’re getting the type of window screen to suit your needs.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

There are different types of screen materials available when purchasing a screen door, but the two main options are fiberglass and aluminum. Fiberglass is lightweight and affordable, but can stretch out, so it needs to be replaced more often. Aluminum has a higher upfront cost, but is more sturdy. Aluminum can be more difficult to install, even if you know how to replace screen door mesh.
