"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."

"We hired David to install a door in an existing frame but flip the direction the door opened. David was very friendly to work with and efficient getting the job done. Most importantly the final result was exactly what we asked for. 5/5 experience. We will be hiring David again for future craftsmen projects."

Window Door Contractors FAQs, answered by experts

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.

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

Among the various entry points into your residence, it's crucial to recognize that your basement windows are arguably the most susceptible. Basements usually have windows facing the side and back yards, often concealed from driveway floodlights, porch lighting, and doorbell cameras. Their vulnerability underscores the importance of reinforcing basement window security to safeguard your home from break-ins.

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.

Professionals ensure repairs not only fix current problems but also prevent future issues, improving efficiency and aesthetics.
