"Jayden, T.J., Marty and Kyle were excellent installers for our window. I've waited a long time for this window and it was so worth it. It feels so clean and bright and I don't even want to shut the shutters. Dust Bunny even stopped by to ensure that we were happy. It's a very hot day and I felt bad for them working in the heat, but they were quick and patient and happy that we were happy."

"It went very well and we are very happy with our new windows. One window was cracked during shipping and they discovered it and ordered a new one right away. A couple weeks later when it came in they replaced it. We felt bad for the guys that did the work because it was the two hottest days of the summer. They did an amazing job while working in the heat. We will recommend Green Valley for their work to people we know that need this kind of work. We will also look to them when we need more work on our house."

"I hired Gabeâ s Interiors to fix a couple weak points on my deck and to fix a deck door that was not closing properly. Gabe and his employees were very kind, respectful, easy to talk to, and professional in the work they did to my deck. They took a job that would have taken me all day to complete and got it done within a half hour. The price was more than fair and appropriate for the amount and type of work that was done. I would recommend this company to anyone looking to make improvements to their home as Iâ m confident they will produce the same results and provide the same level of care as I was given."

Window Door Contractors FAQs, answered by experts

Window repairs cost $175 to $615, depending on the type of repair. Because double-hung windows have two sashes and multiple pieces of hardware, like locks and handles, there are many parts that can break over time. Repairing locks, latches, or other hardware costs about $75 to $200 and is easy to DIY. Fixing one or multiple sashes costs about $200 to $600.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

Whether you should repair or replace a screen door depends on the type and extent of the damage. It is easy and economical to repair a small tear in the mesh using a widely available DIY patch kit. However, if there are large tears, multiple damaged spots, or if the screen is made of a specialized material, replacing the entire screen mesh might be a better long-term investment for a tidier appearance. You should also consider the condition of the frame; if the frame itself is damaged, it's likely time to replace the entire door. Other factors to weigh include whether you want a new style or need a more durable door.

Rescreening your porch can take a few hours to a whole day, depending on the size of the enclosure and the amount of screen that needs replacing. If you decide to have a professional handle the rescreening, be sure to get a timeline and a cost estimate so you know how long you’ll be without the screened-in space.

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.
