"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

Yes, you can replace the screen without removing the door in most cases depending on the frame holding the screen. Doors with removable spline and screen frames make it a snap to replace the mesh while the door remains in place. The best part is that it’s a simple DIY project requiring a few tools in addition to the screen material.

Screen doors have a positive ROI because of their safety features. They add protection from debris, critters, and, depending on the material, even heat. However, storm doors are better than screen doors when it comes to overall protection.

Most standard windows can accommodate solar screens, but specialty shapes or non-standard frames may require custom solutions. It’s important to consult with a professional to ensure compatibility and proper fit for unique window designs. Arched, bay, and fabricated windows often need fabricated screens, which can increase costs and lead time.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

Window repairs cost $175 to $615, depending on the type of repair. Because double-hung windows have two sashes and multiple pieces of hardware, like locks and handles, there are many parts that can break over time. Repairing locks, latches, or other hardware costs about $75 to $200 and is easy to DIY. Fixing one or multiple sashes costs about $200 to $600.
