"Did great work replacing a storm door and an exterior door for us - they look and work great, he even came back out six months later to make adjustments at no cost when one of them shifted a little with the weather."

"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."

"Bob was such a pleasure to work with. His pricing was fair and his work impeccable. The best part about working with him was his communication. These days it seems most contractors are unreliable and unresponsive. That was not at all the case with Bob. I canâ t wait to have him do more work on my home!!"

Window Door Contractors FAQs, answered by experts

Yes, you can fix windows without replacing them. However, this will depend on the severity of the issue and what your needs are. Minor water damage, broken glass, damaged casing, and worn caulking are usually easy repairs. But if there is excessive damage, the windows are constantly foggy, or the windows are very old, it’s best to consider replacing them. Replacement windows cost between $575 and $1,475 per window, or an average of $850 per window. 

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

There are many ways to customize screens, including customizing frame colors and mesh styles to complement your home’s aesthetic.

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.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
