Is professional house washing safe for siding?

Yes. Soft washing is safe for most siding types when performed by trained professionals. The low-pressure application combined with surface-safe detergents cleans effectively without causing damage to vinyl, fiber cement, brick, or painted surfaces.

Will house washing damage plants or landscaping?

No. Professional services use plant-safe cleaning solutions and thoroughly rinse landscaping before and after cleaning. Plants are pre-wet to prevent chemical absorption and receive final rinses to ensure no detergent residue remains.

How often should I have my house washed?

Most homes in North Carolina benefit from house washing every 12–18 months. Homes in shaded areas, near trees, or in high-humidity locations may need cleaning annually to prevent heavy algae and mold buildup.

The House Washing Process: Step by Step

1

Initial Walkthrough and Property Review

When your house washing professional arrives, the first step is a brief exterior walkthrough of your property to understand the scope and identify any special considerations.

During this review, they will:

Confirm the areas being cleaned (entire house, specific sides, etc.)
Identify siding type and condition (vinyl, fiber cement, brick, etc.)
Note any delicate areas or existing damage that needs special care
Review water access and safety considerations

This ensures the correct cleaning method is used for your specific home.

2

Protecting Your Home and Landscaping

Before cleaning begins, professionals take steps to protect your property, plants, and surrounding areas.

This typically includes:

Pre-wetting nearby plants and landscaping to protect them
Covering or avoiding delicate fixtures when needed
Confirming windows and doors are closed
Controlling runoff to protect surrounding areas

Professional house washing prioritizes safety for your home and yard.

3

Soft Washing the Exterior of Your Home

Most professional house washing services use soft washing, not high-pressure washing. This is a critical distinction that protects your home.

Soft washing:

• Uses low water pressure (similar to a garden hose)
• Applies surface-safe detergents that do the cleaning work
• Removes algae, mold, mildew, and dirt at the molecular level
• Prevents damage to siding, trim, and painted surfaces

This method is especially effective for vinyl siding, fiber cement, brick, and painted surfaces.

Cleaning Siding, Trim, and Exterior Features

The technician methodically cleans all exterior surfaces, paying special attention to heavily soiled areas.

Areas cleaned include:

Siding

Soffits and fascia

Exterior trim

Entryways

The cleaning solution is allowed to dwell briefly to break down buildup before being gently rinsed away.

5

Rinsing and Final Inspection

The final stage ensures all cleaning solution is removed and quality standards are met.

After cleaning:

All surfaces are thoroughly rinsed with clean water
Landscaping is rinsed again to remove any residual detergent
A final inspection is performed to ensure quality

This ensures no residue is left behind and that results meet professional standards.

How Long Does House Washing Take?

Average Service Time:

1–2 hours for an average-sized home

Larger homes or heavily soiled surfaces may take slightly longer, but disruption is minimal. Most homeowners are pleasantly surprised by how quick and efficient the process is.

Keep pets indoors during service
