"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

Windows FAQs, answered by experts

Storm windows provide several key benefits. They offer improved insulation and soundproofing, which adds comfort to your home by regulating internal temperatures and blocking external elements. Storm windows also help reduce energy costs by preventing cold or hot air from getting inside. Additionally, they can protect the primary glass in your windows against weather damage.

Arched windows used to be most prevalent in more traditional home styles, like Spanish colonial and Gothic, but they are becoming increasingly popular in modern design. You’ll often find arched windows in new home builds across many styles, including farmhouse and contemporary architecture. This represents a more general trend toward more unique houses with interesting features.

Consider adding sash locks to your windows to fix drafty windows if you don't currently have any. Sash locks in double-hung and single-hung windows help to create a tight seal when windows are shut.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Replacing window glass instead of the entire window is more cost-effective, maintains the frame's aesthetics, and reduces waste. It improves insulation and energy efficiency and can be completed more quickly with minimal disruption to the home.
