"The front of my house was a green mess, Keith and Mary made my ten yr old gray siding & roof looked new. Made my 40 yr old garage roof look like a roof again. Very hard working and courteous on an extremely hot & humid day. Also cleaned my "green" fence back to white w/o me asking. Highly recommend & will use them again. Thanks for a hassle free job!"

Window Cleaning questions, 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.

Professionals remove dust, allergens, and stains while preserving fabric integrity and enhancing the appearance of window treatments.

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

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.

Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.
