"Chris did an excellent job! My wood deck had 3 old layers of stain and it took longer than expected but Chris was able to successfully remove all of the old stain. During the project Chris found 4 deck boards and 2 rail spindles needed replacing and he helped us out greatly by replacing them at an additional cost after talking to us to save me the time of doing it. The deck was stripped, sealed & re-stained. It looks terrific. Great Job! Chris also talked to us about the mold on our siding and how he can help get that clean too so next year we will have him back to help with the exterior mold removal from the house. Thanks Chris and Keep up the Great Work!"

Window Cleaning FAQs, answered by experts

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

Regular cleaning and inspecting seals to prevent fogging and maintain clarity.

Do not mix bleach with vinegar, ammonia, acidic liquids, or other cleaners or detergents as toxic fumes result from the chemical reaction. Mix bleach only with water to avoid dangerous chemical reactions. Even mixed with water to dilute it, bleach can still be harmful to your skin, eyes, and lungs.

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.

Getting a streak-free shine after cleaning your windows requires both the right cleaning solutions—which can either include warm water and dish soap or warm water and rubbing alcohol—and the right tools—namely, a squeegee and a microfiber cloth. To make your streak-free glass cleaner, combine one gallon of warm water with a few drops of dish soap, and mix. Apply with a sprayer or sponge, and then dry with a squeegee, microfiber cloth, or old black-and-white newspaper pages.
