Window Cleaning FAQs, 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.

Professional window cleaning services save time, improve visibility, and enhance the appearance of your home or business. They also help extend the lifespan of your windows by preventing the buildup of grime and hard water stains through comprehensive cleaning.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

Yes, professional window cleaners will clean the surface of the glass on both the inside and the outside. They will usually clean the tracks for your windows, check and clean the weatherstripping, and even disassemble parts of your window, if necessary, to clean and lubricate interior components and moving parts.

In most cases, you should get your windows cleaned one to two times annually, although you might want to complete this task more often if you live in an area with heavy pollen or heavy rain or snowfall that soils your windows. It’s also a good idea to hire a professional window cleaning service if you’re listing your property, as sparkling windows will make a big difference in terms of curb appeal and, potentially, your home’s value.
