Why do I need house washing before painting?

Paint won't bond properly to dirty, mossy, or mildewed surfaces. Painting over contaminants causes premature peeling and failure. Most paint warranties require clean surfaces. Professional washing ensures paint lasts its full lifespan.

How long before painting should I schedule washing?

Ideally 1–2 weeks before painting begins. This allows surfaces to fully dry while staying clean.

Is pressure washing safe before painting?

High-pressure washing can damage siding. We use low-pressure soft washing that's safe and effective for paint prep.

Do painters recommend this service?

Yes, professional painters know proper prep determines paint longevity. We work with Vancouver painting contractors regularly.

Why Choose WashTech for Pre-Paint House Washing

Professional painters know that proper surface preparation determines paint longevity. Painting over dirt, moss, mildew, or chalky surfaces causes premature peeling and adhesion failure. WashTech provides pre-paint exterior house washing using soft wash cleaning; removing all organic growth, dirt, and contaminants so new paint bonds properly.

We serve Vancouver homeowners and painting contractors with biodegradable cleaning that prepares siding, trim, fascia, and soffits. Save money on your paint job by ensuring it lasts. Proper prep is essential for paint warranty compliance.

Ensures proper paint adhesion

Paint manufacturers require clean, dry surfaces for warranty coverage. Painting over moss, mildew, or chalky residue causes premature failure. Our soft wash cleaning removes all contaminants so paint bonds correctly.

Soft wash safe for all siding types

Low-pressure cleaning (under 500 PSI) with biodegradable solutions. Safe for stucco, wood, Hardie board, vinyl, brick, and painted surfaces. Pressure washing can damage delicate siding and void warranties.

Removes all organic growth

Moss, algae, mildew, and mold must be killed at the root, not just rinsed off. Our treatment ensures these don't grow back under new paint within months.

Painters trust us

We work with Vancouver painting contractors regularly. We understand timing, surface prep standards, and paint manufacturer requirements.

Safe for landscaping and won't leave chemical residue that interferes with paint adhesion.
