"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

Some hardware or specialty window stores in your area may repair damaged screens, but it’s less time-consuming, more convenient, and potentially more affordable to hire a screen repair technician to come to your home to do the work on-site. The screen technician will have the tools and experience to get the work done the same day, and they can inspect other screens while there to help avoid repeat repair costs in the future.

Ensures proper fit and function, maximizing insect protection and airflow.

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.

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.
