Protect & Beautify Your Home

Why Choose Our Siding Cleaning?

Our soft wash techniques safely eliminate algae, dirt, and stains — restoring your home’s curb appeal.

Our Siding Cleaning Process

Over time, your home's siding collects dirt, mold, algae, mildew, and pollution — leaving your exterior looking tired and neglected. Worse, organic buildup can degrade materials, trap moisture, and lead to costly repairs. At Duboff Exterior Cleaning, we provide safe, efficient, and effective siding cleaning using our soft wash system.

Unlike high-pressure washing that can force water behind your siding or cause surface damage, our low-pressure soft wash process gently removes stains, kills algae at the root, and restores the beauty of your home’s exterior — all without damage.

Here’s what’s included in our siding cleaning service:

Whether you’re tackling HOA requirements, preparing to paint, or just want your house to shine — our siding cleaning service makes your home look brand new.

Gentle on surfaces. Tough on grime. Dramatic results.

Why Siding Needs Specialized Cleaning

Siding is one of the most visible parts of a home and also one of the easiest surfaces to damage with improper washing. Vinyl can trap grime in textured surfaces, painted wood can be stripped by excessive pressure, and fiber cement can suffer from repeated aggressive cleaning. Our soft wash approach is designed to remove biological growth and surface contamination while reducing the risk of water intrusion or finish damage.

Many homeowners combine siding cleaning with roof cleaning or gutter cleaning to restore the entire exterior at once.

Common Problems We Remove

Why High Pressure Can Be Risky

Traditional high-pressure washing can force water behind siding panels, disturb caulking, and damage painted or weathered surfaces. Soft washing uses lower pressure and cleaning solutions designed to break down buildup more safely and more thoroughly.

When to Schedule Siding Cleaning

If you notice green buildup, dark staining, cobweb accumulation, or a dull appearance on shaded sides of the home, it may be time for professional siding cleaning. Regular maintenance helps preserve curb appeal and can reduce long-term wear on exterior finishes.
