"My windows were so inefficient I couldn’t get the temperature above 63° in the winter. I used to put plastic on the windows and the wind would blow the plastic. Lol. Also there was a significant sound improvement living near Highway 441. Installation was bing bang boom and finished within a couple hours. (Installed 5 Slider WINDOWS Fall 2018)"

"Kris W. Made my dream vision of our bathroom area a reality. I’m glad I went with this company. They are very responsive and have excellent communication skills, with great customer service. In the past, I never had good luck with contractors on our home remodels, but they exceeded my expectations. We couldn’t be more happy! Thanks, Kris!"

"The job was completed quickly and professionally. They really did a good job both protecting shrubbery by house and cleaning up any nails and debris after the job was done. They provided a folder with all the info I needed to know about them and their work, even references. They expressed a real concern for my being happy with their work, answering any questions I had or might have. And the price was more than fair. I would definitely recommend them."

"I did not do the project yet. I am still in the planning stage. I have not decided if I am going to do the egress windows or an addition. Stony Creek Builders were very professional when they called to ask when I was going to do the project and very upfront on what the costs were going to be."

Window Door Contractors FAQs, answered by experts

No, it’s not safe to leave a doggy door open. It might be more convenient, especially at night when you just want to lay in bed. However, when you leave it open, it increases the chance of other critters getting in without your knowledge. Also, it leaves your pup unsupervised for hours at a time.

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.

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

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.
