"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."

"Gus and John were the technicians who came out, and I was super impressed with their work. They kept everything really clean, and honestly, watching them replace the rollers under the door was amazing they're so skilled! The door operates so smoothly now, it was definitely well worth the price"

"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."

Window Door Contractors FAQs, answered by experts

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

Most solar screens last 10 to 15 years, depending on the material quality, exposure to weather, and the level of maintenance. High-quality materials and regular cleaning can extend their lifespan, while harsh climates or neglect may shorten it. Routine cleaning, inspecting for damage, and avoiding harsh cleaners can help extend the lifespan of your screens.

A screened-in porch requires maintenance to keep the screens clean and in good shape, and you may have to do some screen repair or replacement from time to time. A screen porch isn’t an all-season porch, so the weather can get in, including wind and rain.

Ensures proper fit and function, maximizing insect protection and airflow.
