"We had several windows and doors replaced and I was really impressed with the new windows and doors as well as the professional installation by Perry and his crew. They made sure everything was square, clean, and caulked. Great job! I highly recommend Metropolitan High Performance Windows."

"Outstanding work. Will and Bobby did a great job on our glass sliding door. Very reasonable price and theyve cleaned up the job site after work is done. My husband had the issues on the sliding door for many years, been asking him why he wont have it fixed he said he cant find anyone who has good reviews etc. So luckily we found Empire Sliding door Moreno valley. TY."

"Michael was communicated well and often to confirm the work and the date and time of when the work was to be completed. He arrived early and replaced the door and hardware without incident. He did need to replace the door casing as well since it was old (it's been there since the house was built in 1971) so this was understandable. It ended up costing a little more than originally bid but the cost increase was reasonable given the additional work Michael had to do. The door was hung perfectly and is solid and water tight. Great job. We would hire him again when needed."

"Rigo ordered and just installed a sliding glass door in the back of our house. He did a great job! The door was a custom order and took four months to receive. Rigo kept us updated every step of the way regarding the status of delivery. Once we received the door, Rigo completed the installation exactly on schedule and did a very professional job. Not only did he do a great job on the installation, he also added and painted custom framing inside and outside that we requested. The craftsmanship was excellent. When Rigo was doing the installation, my wife notice a small tare in the screen from the manufacturer. Rigo removed the screen from the frame and replaced it with a new one during the same visit. Originally, we spoke to a number of contractors, including some from Lowes and Home Depot, but I am so glad we decided on Rigo. He did a fantastic job from beginning to end and was always very cheerful and pleasant, even when we made additional and unplanned requests. I would highly recommend Rigo to anyone who is looking for a good contractor to install doors or windows."

"I had two people come out that could not repair my sliding glass door. I initially understood; it is over 30 years old. Near Me Sliding Door (Juda), came out and came up with this idea (thought outside the box) and my door works perfectly. I am very happy with their work and their honesty."

Window Door Contractors FAQs, answered by experts

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

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.

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.

The best type of window screen for your home depends on your region and your family’s needs. While fiberglass window screens are a popular, affordable, and easy-to-find choice, you may be looking for different benefits, such as a more high-end look, increased strength, or extended durability. The best window screen meets the demands of your home and its residents while staying within your budget.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.
