"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

While sometimes used interchangeably, screen doors and storm doors have key differences. Screen doors are simple structures, typically composed of just a frame and a screen, designed to keep out bugs while allowing air circulation. In contrast, storm doors are heavier and more complex, built to protect your home's main entry door from weather and intruders. They usually feature an aluminum frame with interchangeable tempered glass and screen panels, allowing you to switch between ventilation and insulation. A storm door offers more protection and versatility but generally costs more than a basic screen door.

Solar screens use a thick mesh of polyester to block out the UV waves and solar heat. While they are more expensive at about $7.50 per square foot, they can protect your porch or hardwood floors from sun damage and keep the room or porch on the other side of the patio cool.

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.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.
