Window Cleaning

Will the rain ruin my clean windows?

Usually not. Rain is actually deionized and doesn't leave spots when it dries. If water runs down a dirty wall onto a window, it may leave spots.

Do you offer free rain checks?

Yes! If rain does leave spots on your windows within 7 days after we professionaly clean them, we will happily come back and reclean any affected windows.

Do you clean interior and exterior of windows?

Yes, we do! We train all our technicians to manage water inside your home, catch their water as they clean the glass and ensure no drips are left on your floors.

Will you get my carpet dirty?

No. Our technicians will put on shoe covers before entering your home and ensure no water is dripped as they make your windows sparkle.

I have hard to reach windows. Can you clean them?

Yes! We have an array of all types of ladders; ladders you probably have never seen before. We also use carbon fiber poles to expertly clean windows that are inaccessable by ladder. We can clean up to 4 stories with ladders and up to 6 stories with our water fed pole systems.

Pressure Washing

Will pressure washing damage my siding?

We are often asked this questio. The honest answer is, it all depends on the user. A hammer can be a dangerous tool in the hand of a novice, but hits it's mark in the hand of a pro. Our technicians have been trained to identify and adapt the distance, angle and PSI to pressure wash any surface safely and effectively.

Can you remove algae?

Yes. We use a combination of chemical and pressure to effectively remove algae from a service. The proportion of each depends on the surface we are working on.

Is algae dangerous?

Algae can be dangerous. It can keep a surface moist, which can increase deterioration. If it's on a walkway, that walkway can become very slippery and potentially cause a fall. One must also be very careful to ensure the algae is not actually black mold. Black mold brings other very serious respitory and health risks. Whether algae, mold, black mold, or moss, we can safely and effective remove it from your building and property.
