"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

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

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

Window capping costs between $1 and $2 per linear foot. Since your average window size is 24 by 36 inches, you’re looking at 10 linear feet in total, or $10 to $20 per window. Labor adds another $30 to $100 per hour to the project. If you have custom windows, you’ll spend more to have your windows capped. Fiberglass tends to cost more than vinyl and aluminum, while vinyl costs the least but has the shortest lifespan and may have a higher long term cost.
