"The crew Patsy sent did an excellent job in installing the new door that we purchased. A fair amount of field fitting was required which they handled professionally. We are very pleased with the work and would hire again."

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"My name is Jason Haslbeck and I live in Chester County, PA. My wife and I have used Castle Windows for the replacement of all our windows, a new front door and now a new custom French Door slider (three separate project installations). Our sales representative, Roberto Munoz, has been an absolute pleasure to work with for all of our installations. Their customer service is excellent and their products are the best in the industry. Their lifetime warranty is legitimate and very valuable. Due to the Corona Virus, our latest project design consultation (French Doors) was done over the telephone using a ZOOM application. Very convenient technology and the presentation was very professional. On a personal note, our sales representative (Roberto) is a very faith based, honest human being and we have never been happier with a contractor or sales representative. I would highly recommend asking for Roberto Munoz as your sales representative as he is very knowledgeable, professional and courteous. Overall, from my experiences, Castle Windows is the best window and door company in the region. We did extensive research in comparing them to Pella, Anderson and other companies and Castle's product quality, installation and pricing was the best value by far. I would normally never take time out of my day to write a review, but my experience with Castle Windows (and Roberto Munoz) is one that deserves recognition. Jason & Hope Haslbeck Chester County, PA"

Window Door Contractors FAQs, answered by experts

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. 

Yes, you can absolutely put a screen on a casement window, and most casement windows come with screens. Unlike with a double-hung, single-hung, or sliding window, the screen in a casement window sits on the inside of the window so that the sash can freely open outward. Screens are especially important for casement windows because the large window opening the window provides leaves your home more open to bugs and outside debris than most other types of operable windows.

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.

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.  

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.
