"My sliding glass doors are working so smoothly almost like new. The house was built in 1959 so the door are not new but they function like new ones. I also needed to change the 7 pieces of glass in a jalousie window. The Technician knew exactly how to do it and fixed them in a jiffy."

"Bottom hinge had completely come out and the door wouldn’t close. Gary replaced the top short screws with some longer screws in the hinges to fix the door and secure the home. I definitely would recommend him. He was fair knowledgeable and was quick to get to us."

"Guinn & Sons replaced all of our windows and doors with impact at my house. I am pretty picky so they took the time to explain the options and products to ensure I was happy. Very communicative from start to finish and we love how everything turned out. They kept everything clean during installation too. I’m a realtor in Miami and I refer all my clients to them, and everyone has been very happy! I highly recommend them."

"I recently had the pleasure of working with ASP SuperHome for the installation of new impact windows and doors in my home, and I couldn't be more satisfied with their service. From start to finish, the entire process was handled with the utmost professionalism. I would like to especially thank the salesperson Peter for his knowledge, commitment and timely response to issues throughout the project. He helped me select strong 9/16” windows with visible transmission of 60% (thus, the outside from inside looks bright) while the solar heat gain was limited to 32% (thus, the house is protected from excessive heat). The windows are rated for +90 and -90 pressure, which is well above the Miami Dade guidelines. The doors are strong and aesthetic. In summary, I received strong, hurricane protection doors and windows that also shield me from heat and noise, move smoothly, and are visually appealing. The quality installers at ASP, Yosyenny and Emilio, demonstrated exceptional skill and attention to detail. They worked diligently and efficiently, ensuring that each window and door was perfectly fitted and securely installed. Despite the extensive work, they maintained a neat and organized workspace, leaving no mess behind. Roy is also a capable installer. Thanks also to Michel and Sergio for project management, and to Emily, Luisa and JJ for the coordination. Overall, my experience with ASP was outstanding. Their commitment to providing high-quality service and their dedication to customer satisfaction truly set them apart. I highly recommend them to anyone in need of window and door installation services."

"I called him last night to replace a bedroom door, and it was replaced by 1pm today. I'm extremely happy with the quick and efficient service provided, my only fear is my new door looks better than all the rest so I will be calling him soon enough to have them all replaced!"

Window Door Contractors FAQs, answered by experts

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.

Yes, you can fix windows without replacing them. However, this will depend on the severity of the issue and what your needs are. Minor water damage, broken glass, damaged casing, and worn caulking are usually easy repairs. But if there is excessive damage, the windows are constantly foggy, or the windows are very old, it’s best to consider replacing them. Replacement windows cost between $575 and $1,475 per window, or an average of $850 per window. 

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.

If you’d rather repair your screen door mesh than replace it, you can patch it. Purchase a mesh patch for screen doors with small holes or tears, especially if the mesh is pretty new. Hardware stores and websites sell mesh patches that are easy to apply with an adhesive or a warm hair dryer. Keep in mind that repairs won’t look as aesthetically pleasing in most cases as a full replacement. 

If you’re not an experienced DIYer, consider hiring a local patio repair contractor to rescreen your porch or sunroom. Unless you’re only repairing a small rip or hole, this project is not an easy job. A professional can also make recommendations for materials that will work best for your porch.
