"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!"

Window Door Contractors FAQs, answered by experts

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

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.

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.

No, it’s not safe to leave a doggy door open. It might be more convenient, especially at night when you just want to lay in bed. However, when you leave it open, it increases the chance of other critters getting in without your knowledge. Also, it leaves your pup unsupervised for hours at a time.

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.
