"We had DMD intall a bay window for us in the 80's and were so pleased with the results. Needing to place windows and doors, I was delighted to see they were still here. Again, Bill was most accommodating and and responded to questions in a timely manner. Chad, Alex and Kevin came to demo and replace 2 sliding glass doors and several windows. Their work ethic and teamwork was unbelievable. I HIGHLY recommend DMD for any work you may want done."

"RC arrived in a timely manner to provide me an estimate on installing a metal cellar door. However, when I tried to find a dealer for the size we needed, it became impossible. After an internet search, I settled on a door that would need an extension. While RC would have been able to install it, the cost would escalate exponentially since the door is pricey. He told me he could build a durable cellar door using treated lumber, prime it, paint it, and install all necessary hardware for a lower price. A day later he gladly came in and made a minor change that I requested. The end product was perfect, and he saved me some change. I am glad I went to Angi to find this professional."

"Our window started leaking after a big rain storm and I wasnâ t able to isolate the source of the leak. Jason came out the same day and was able to identify the issue with the caulk around the glass. He answered all of our questions and provided a very reasonable quote which they came back to fix the following week after the window had dried out. We had a couple other windows we were worried about sealed at the same time. Great service and workmanship! I would recommend them for all your window and glass needs."

Window Door Contractors FAQs, answered by experts

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.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.

The screen material you choose depends on your needs. Here are some differences to consider:

  • Fiberglass is the least expensive but needs replacing more often.

  • Aluminum suits almost any job and doesn’t stretch as easily as fiberglass. 

  • Pet-resistant screens are more expensive than fiberglass or aluminum, but they’re also wind and weather-resistant. 

  • Metal screens, like stainless steel, are the most expensive material for rescreening your porch or sunroom. However, they last for years and are golf ball-resistant.  

Adding a window to a brick house costs $3,100 to $10,575. Because you’ll need to make changes to the structure of the home, the cost will include obtaining permits and hiring the best pros for this complex job. Larger windows will cost more to install, and the cost can vary based on the window frame material you choose.
