"The 2 workers went above and beyond. Made a badly stained and mildewed awning look brand new. Keith also fixed 2 door screens that had been pushed out by my grandchildren and my dog by accident. I did not ask he just did it. And Mary came back in the house to look into a smudge in a window that I look out of all the time. No attitude, just happy to take care of it. Very pleasant to have around. Had no qualms over having them in my house. Ron, you have a great crew."

"Xpress Powerwashing’s work was outstanding. My house and vinyl fencing was softwashed and my deck and furniture was power washed. They meticulously pay attention to detail. My windows were spotless. A friend asked if I had gotten my house resided it was so clean. I highly recommend them. They are also reasonably priced. Well worth it."

Window Cleaning FAQs, answered by experts

Yes, using appropriate techniques and solutions for material-specific care.

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.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

Yes, you should plan on being home when a window cleaner is cleaning your windows. The professional will clean both sides of the glass and will likely disassemble parts of your windows from the inside to clean and inspect the inner components, including the balances and weatherstripping. Much of this work requires interior access to your home, which means someone will need to be home to provide access to the window cleaner.

Pros offer comprehensive cleaning that addresses areas you might overlook, ensuring an immaculate home.
