"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!"

"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 questions, answered by experts

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.

Professionals use HEPA vacuums, industrial-strength cleaners, and microfiber cloths for effective cleaning without damaging surfaces.

Costs depend on window count, height, accessibility, labor, and whether interior and exterior cleaning is required.

Access to professional tools ensures streak-free finishes and safety in hard-to-reach areas.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.
