Window Cleaning questions, answered by experts

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

Regular cleaning and inspecting seals to prevent fogging and maintain clarity.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

Window washing usually refers to cleaning dirt and other debris off of the exterior of your windows, while window cleaning is a much more involved process that addresses the outside and inside of the glass, as well as the interior components. Window washing is more to improve the aesthetic of your windows, while window cleaning can improve performance, reduce the risk of damage over time, and even improve your home’s energy efficiency.

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.
