"I want to thank Jacob Tryon for selling me my Provia windows and sliding glass door. I want to thank the crew that installed them: Lorenzo, Ernesto, Pablo, Jonathan and Edgar. The crew removed and replaced 9 windows and a sliding glass door in 1 day! I also want to thank the 2 gentlemen that came and replaced the stucco, painting and replacing of my bars on my home. All the way through the whole process I was pleased with the professionalism. Everyone answered all my questions along the way. My Provia windows have more features then I knew. I absolutly LOVE them! I would recommend Flawless Solutions to anyone. I have already talked to some of my neighbors that asked about my new windows and my family."

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.

You can trim an overhead garage door screen to fit your garage door opening. This is a particularly helpful hack if you have an irregularly sized garage door opening but are still interested in installing a garage door screen to keep pests and debris out. Trim the garage door screen carefully to avoid unsightly edges or an uneven fit.

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. 

Tears, holes, or difficulty in opening and closing suggest a need for repair.

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.
