Get matched with top window treatment pros in Sutherland, VA

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.

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

No, windows cannot be made 100% soundproof. Even the most advanced setups still allow some sound to pass through because windows are designed to let in light and are not completely sealed from the outside. While you cannot achieve complete silence, significant noise reduction is possible, with some noise-reduction windows blocking up to 95% of outside noise.

The goal is to minimize air gaps, add mass, and reduce vibration. To block out as much noise as possible, consider hiring a professional to install new double-pane, triple-pane, or laminated windows. You can further enhance soundproofing with airtight seals, glass inserts, shutters, or sound-dampening curtains. With the right upgrades, you can block out traffic, neighbors, and other city noise to a much quieter level.

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