"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’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

For most common repairs, a professional window repair service can fix a window in one to three hours. However, replacing window frames or repairing a large, multi-pane window will likely take longer to complete. For comparison, a window installation or repair professional should be able to replace up to 15 windows per day.

Adding a window to a brick house costs $3,100 to $10,575. Because you’ll need to make changes to the structure of the home, the cost will include obtaining permits and hiring the best pros for this complex job. Larger windows will cost more to install, and the cost can vary based on the window frame material you choose.

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence. 

There are different types of screen materials available when purchasing a screen door, but the two main options are fiberglass and aluminum. Fiberglass is lightweight and affordable, but can stretch out, so it needs to be replaced more often. Aluminum has a higher upfront cost, but is more sturdy. Aluminum can be more difficult to install, even if you know how to replace screen door mesh.
