"We had DMD intall a bay window for us in the 80's and were so pleased with the results. Needing to place windows and doors, I was delighted to see they were still here. Again, Bill was most accommodating and and responded to questions in a timely manner. Chad, Alex and Kevin came to demo and replace 2 sliding glass doors and several windows. Their work ethic and teamwork was unbelievable. I HIGHLY recommend DMD for any work you may want done."

"RC arrived in a timely manner to provide me an estimate on installing a metal cellar door. However, when I tried to find a dealer for the size we needed, it became impossible. After an internet search, I settled on a door that would need an extension. While RC would have been able to install it, the cost would escalate exponentially since the door is pricey. He told me he could build a durable cellar door using treated lumber, prime it, paint it, and install all necessary hardware for a lower price. A day later he gladly came in and made a minor change that I requested. The end product was perfect, and he saved me some change. I am glad I went to Angi to find this professional."

"David did an excellent job installing an interior door for a master bathroom. His craftsmanship and attention to detail was top notch. The finished door, trim, hinges and privacy door knob all perfectly matched our existing interior doors. I enjoyed working with him and would not hesitate to hire him again for future projects."

"Our window started leaking after a big rain storm and I wasnâ t able to isolate the source of the leak. Jason came out the same day and was able to identify the issue with the caulk around the glass. He answered all of our questions and provided a very reasonable quote which they came back to fix the following week after the window had dried out. We had a couple other windows we were worried about sealed at the same time. Great service and workmanship! I would recommend them for all your window and glass needs."

Window Door Contractors FAQs, answered by experts

Some local utilities or state programs offer rebates or tax incentives for energy-efficient upgrades, including solar screens. Make sure to check with your local energy provider or government agency to see if you qualify for any cost-saving programs. Federal tax credits may also be available for qualifying window and exterior home upgrades.

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.

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. 

Typically every 10-15 years or whenever they show signs of wear and tear.

Many kinds of window screens, such as solar screens, are designed to reduce the amount of harmful ultraviolet rays that pass through them and enter your home. The materials typically have UV-blocking properties. However, they may not completely eliminate all UV rays from passing through your home. Different window screens are designed for different purposes, and not all are designed to block or reduce UV rays. Do your research to make sure you’re getting the type of window screen to suit your needs.
