FAQ

We recommend having your house washed at least once per year. This provides consistent protection from harmful algae, mold, and other contaminants.

Each job is unique. The time it takes to complete is dependent on many factors, such as the size of the surface and the amount of buildup. Rest assured, our technicians will work on your property until they deliver the best results possible.

Our experts ask a few questions and measure your property using state-of-the-art satellite measuring technology. This gives us precise square footage so that we can provide the most accurate quote possible.

Yes, absolutely! Washing the exterior of your home can add up to $15,000 to the sale price, according to the National Association of Realtors.

No. For your convenience, you do not need to be home. All we ask is that you close your windows and doors on your service date and provide access to a working water spigot.

Yes, we do require access to a working water spigot on the outside of the house.

Our team works in the wind and rain. If the weather is too extreme, our technicians will reach out regarding rescheduling the service.

Yes, it will. The “green stuff” you see on your siding is a form of algae that affects thousands of homes each year. Our process is designed to safely eliminate not only algae from your siding, but also mold, dirt, grime, and other contaminants.

A house wash utilizes a soft wash process that combines safe pressure with biodegradable cleansers to remove dirt, mildew, algae, and other contaminants from your home’s exterior.

No, our process is not designed to clean out gutters. During our house wash, we soap and rinse the exterior of your gutters but do not physically remove debris from the inside.

It is NEVER recommended to ‘power wash’ a roof. Therefore, we perform what is called a “roof treatment,” where we apply a specialized algaecide designed to eliminate moss, lichens, and black streaks. This is performed at a very low pressure to avoid structural damage, providing the best results possible for your home.

The black streaks on your roof are an infestation known as Gloeocapsa Magma. This algae eats away at the limestone filler in your shingles, leaving behind a dark residue. Our roof treatment is designed to remove these black streaks and neutralize the infestation at its roots.

It is not recommended to physically remove moss from your roof at the time of service. However, the good news is that our roof treatment neutralizes moss and lichens at their roots. This allows them to fall off the roof over time naturally.

The length of time it takes them to fall off naturally is dependent on the depth to which their roots were embedded. For this reason, we offer a one-year warranty on our roof treatment that starts on the date of your original service.

No. These stains may lighten up in color, but our process is not designed to remove oil/rust stains or inorganic marks.

Yes, we do! At Zen Prowash, we guarantee to deliver the best results possible for your property using our safe and effective processes, or your money back!

At this time, only cash payments are accepted for power washing services. Payment is expected once the final service walkthrough is completed.
