"Did great work replacing a storm door and an exterior door for us - they look and work great, he even came back out six months later to make adjustments at no cost when one of them shifted a little with the weather."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

Window Door Contractors FAQs, answered by experts

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.

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

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

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
