They cleaned everything out — and gave tips to help us avoid it again.
A clean surface is essential for a long-lasting paint job
We wash your exterior thoroughly before painting to remove grime, chalk, and mould — giving your new paint the best chance to stick and look sharp. Our work means your painter starts on the best possible surface, and your final finish looks better for longer.
Services We Offer
Surface Prep for Painting
Paint needs a clean surface to stick properly. We wash away dirt, grime, and contaminants so your new paint will last.
Mould and Chalk Removal
We remove chalky residue and mildew from weatherboards and cladding — critical steps that make a visible difference to your final paint job.
Paint-Ready Dry Finish
We ensure surfaces are not just clean, but dry — no hidden moisture to ruin a fresh coat. It’s the prep your painter hopes you’ve done.
Wash Before Colour Change
Switching colours? We help reset the surface so your new colour shows clearly and evenly — no patches or streaks.
