"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

Picture windows are still in style, even though they are one of the oldest types of windows. Other windows, like single- or double-hung windows and casement windows, have increased in popularity because they can open up for fresh air. However, homeowners still love the way a picture window can frame their lush outdoor garden or other pleasant neighborhood views.

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.

The most common types of window frames include frame and sash, metal or aluminum frames, composite frames, fiberglass frames, vinyl frames, wood frames, glass or glazed frames, and insulated frames. Frames can also be categorized by operating types, such as awning frames, single/double-sliding frames, fixed frames, casement frames, and single/double-hung frames.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

When your double-hung window upper sash keeps falling down, it means you could be letting out warm air in the winter or cool air from the AC in the summer. That means your HVAC system works harder to warm or cool the house, costing you extra on electric bills.

If the lower sash continues to fall down, it means when you’ve popped open the window for fresh air, it could slam shut. In addition to being inconvenient, this could be dangerous if you have small kids, children, or pets that like to hang out by the window.
