"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."

"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

The cost of a window repair varies significantly depending on which part is damaged. Here is a breakdown of common repairs and their estimated costs:

  • Broken seal or fogginess between panes: $70–$245

  • Cracked pane: $40–$100

  • Broken glass: $200–$2,000

  • Sash, seal, or track repair: $200–$600

  • Latch or hardware issues: $75–$200

  • Broken window frame: $175–$1,000

  • Window screen replacement: $140–$480

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.

Common problems include leaks, broken glass, and damaged frames. Regular maintenance prevents extensive damage.

The most affordable way to screen in a porch is to add a base track system to an existing wooden frame. The whole process should cost around $2,000 for supplies, depending on the size of your porch. It’s much pricier to build a screened-in porch or sunroom from scratch—and you’ll probably need to hire a contractor for a project like that.

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.
