"Bought an older home which I remodeled including a 200sf addition. No idea when the windows were last cleaned (they weren't after the remodel) so they were pretty grimy. Stephen did a fantastic job inside and out (including glass storm windows) and they now sparkle! He's professional, thorough, easy to schedule, gave a realistic bid and didn't waste any time getting down to work. I'll hire him again. Highly recommend."

"Excellent experience from start to finish! The team was professional, friendly, and arrived on time. They did an amazing job cleaning our windows—they're absolutely sparkling, and I didn't realize how much brighter the house would look afterward. They were careful, efficient, and left everything clean when they finished. I highly recommend this company to anyone looking for quality window cleaning and outstanding customer service. I'll definitely be using them again!"

Window Cleaning FAQs, answered by experts

All of the things you use to help you get clean can leave your shower door looking dirty. Water can leave mineral deposits as well as unsightly spots when drops of water dry on the glass. Soap and shampoo can cause build-up and residue that leaves a layer of soap scum in your shower, which then attracts dirt. Mold and mildew can also contribute to dirty shower doors; these fast-growing organisms thrive in areas with poor air circulation, damp conditions, and residue from things like soap and shampoo.

Hot water removes grime more efficiently than cold water and evaporates more quickly so that your windows will dry faster. However, you may want to use cold water instead if your windowsill paint is chipping or peeling because heat can worsen this condition.

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.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

Smoke stains, grease buildup, mold, and water spots are common reasons for hiring professional cleaning services.
