Pressure Washing
-
Safe, effective cleaning for all surfaces
-
Ideal prep for painting, sealing, or restoring
-
Grime, mildew, and stains removed without damage
Our Philosophy
A clean surface is the foundation for lasting results. Pressure washing isn’t just cosmetic, it’s essential prep work and a powerful way to renew your space.
At Dan Gogh Paint Co., we approach pressure washing with care and precision. Whether it’s driveways, decks, siding, sidewalks, roofs, or catchment tanks, we use the right equipment and techniques to remove buildup without damaging surfaces. It's the perfect way to restore curb appeal and ensure surfaces are ready for painting or sealing. Let us handle the heavy lifting and bring your property back to life.
Who Is This Service For?
-
Homeowners preparing their property for exterior painting or staining — surface cleanliness is critical for paint adhesion
-
Property owners whose driveways, pathways, or patios have accumulated algae, moss, or organic staining
-
Hilo and Puna residents whose properties accumulate significant biological growth due to high rainfall
-
Coastal property owners dealing with salt deposits and biological growth on exterior surfaces
-
Volcano and Puna homeowners with vog residue accumulation on exterior surfaces
-
Landlords and property managers refreshing a rental property's appearance and preparing surfaces for repainting
-
Homeowners who notice their roof is looking dark — dark patches on roofs are typically algae and lichen growth that shortens roof life
How Pressure Washing Works — Our Process
-
18. Assessment — We inspect all surfaces to be washed, identify any delicate areas requiring soft-wash techniques, and check for existing damage that should be documented before cleaning begins
19. Equipment setup — We use professional-grade pressure washing equipment with adjustable pressure settings and appropriate nozzles for each surface type
20. Pre-treatment where needed — Heavily soiled surfaces or areas with significant biological growth receive a pre-treatment solution that breaks down organic matter before washing begins
21. Surface washing — We work systematically across each surface, maintaining consistent technique and pressure to ensure even cleaning without streaking or surface damage
22. Soft wash where required — Delicate surfaces including painted areas, roofing materials, and older painted timber receive lower-pressure soft-wash treatment to prevent surface damage
23. Rinse and inspection — After washing, all surfaces are thoroughly rinsed and inspected for any remaining soiling or missed areas
24. Post-wash assessment — We walk through the completed wash with you and advise on any surfaces that may need additional treatment or repair before painting or sealing
The Pre-Paint Pressure Wash — Why It's Non-Negotiable
If you're planning an exterior paint job, professional pressure washing beforehand is not optional — it's essential. Here's why:
Paint applied over dirty, contaminated, or biologically active surfaces will fail. Mould and algae continue growing beneath a paint film, causing bubbling and peeling within months. Vog residue and salt deposits reduce adhesion so significantly that paint can literally be peeled away by hand within a year of application. Dust, cobwebs, and organic contamination prevent primer from bonding properly to the substrate.
At Dan Gogh Paint Co., pressure washing is an integrated part of our exterior painting process — we don't treat it as an optional add-on. Every exterior paint project we undertake begins with a thorough surface clean. This isn't just about appearance; it's about ensuring that the paint we apply has the best possible surface to bond to, maximising the longevity of your investment.
Hawaii-Specific Pressure Washing Challenges
• Black algae and lichen — Common on Big Island roofs and driveways, particularly on the east side. Requires specific treatment solutions combined with appropriate pressure
• Vog residue — The sulphur-based film that accumulates on Puna and Volcano-area properties requires specific neutralising treatment, not just high-pressure water
• Red dirt staining — Hawaii's distinctive red volcanic soil stains concrete, pavers, and painted surfaces. Pre-treatment before washing significantly improves results
• Mould and mildew — Hilo's humidity creates ideal conditions for rapid surface mould growth. Soft-wash with mould-inhibiting solutions provides longer protection than pressure alone
