"I was very pleased with Sentry Access, from start to finish. I had the opener replaced. My older garage door (20+ years old) now operates and sounds like a new door. Richard, the technician who did the work, did an outstanding job on both the install and the "tune-up" of the door. I am 100% satisfied with the work from this company, and highly recommend them."

"I contact AMG Doors through a recommendation from a friend. I contacted Michael and he was very knowledgeable about the different types of door materials and what material would work best for my area ( I get a lot of sun at my front door). Michael talked me into getting a thermatru front door and I obsoletely love it! AMG Doors already has a patio door on order for my home!"

"Before setting in my window, James allowed me to paint the 3 support posts which would have looked horrible if they weren’t painted. Victor did a really nice job of putting in the garden window panes and reinserting the rubber sealing strips."

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

Window Door Contractors FAQs, answered by experts

Garage door screens can expand your living space, turning a garage into a home office, gym, or entertainment space. They provide comfortable ventilation, insect control, and privacy, allowing you to enjoy your space all year round. Consult a local garage door screen installer to add this feature to your space.

Yes, you can fix windows without replacing them. However, this will depend on the severity of the issue and what your needs are. Minor water damage, broken glass, damaged casing, and worn caulking are usually easy repairs. But if there is excessive damage, the windows are constantly foggy, or the windows are very old, it’s best to consider replacing them. Replacement windows cost between $575 and $1,475 per window, or an average of $850 per window. 

Most solar screens last 10 to 15 years, depending on the material quality, exposure to weather, and the level of maintenance. High-quality materials and regular cleaning can extend their lifespan, while harsh climates or neglect may shorten it. Routine cleaning, inspecting for damage, and avoiding harsh cleaners can help extend the lifespan of your screens.

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.
