FAQ

What is the difference between pressure washing and soft washing?

Pressure washing uses high‑pressure water to clean durable surfaces like concrete, driveways, and sidewalks. Soft washing uses low pressure combined with specialized cleaning solutions to safely wash siding, roofs, and other delicate surfaces. We choose the best method for each job to protect your home.

How often should I have my home exterior cleaned?

Most homes benefit from exterior cleaning once a year. However, heavily shaded areas, homes near trees, or properties with frequent algae growth may need cleaning more often.

Do you offer gutter guard installation?

Yes. We provide professional gutter cleaning as well as gutter guard installation to help prevent clogs, reduce maintenance, and keep water flowing properly throughout the year.

Will pressure washing damage my siding or roof?

No. We never use high pressure on surfaces that could be damaged. Roofs and siding are cleaned using our soft wash system, which is designed to be gentle, safe, and highly effective.

Do I need to be home during the service?

You don’t have to be home as long as we have access to the areas we’re cleaning and an outdoor water source. We’ll communicate with you before and after the service to ensure everything is completed to your satisfaction.

Are your cleaning products safe for plants and pets?

Yes. Our solutions are industry‑approved, eco‑friendly, and safe when applied correctly. We take all necessary precautions to protect landscaping, pets, and surrounding areas.

What makes your company different from other exterior cleaning services?

As a family‑owned business, we take pride in delivering honest work, reliable service, and results we’d be proud to see on our own home. We use professional techniques, treat every property with care, and prioritize customer satisfaction above all.
