Why Nelson homes call us first
Local water blasting crew working across central Nelson. House washing, roof treatment, driveways, gutters, the lot.
Nelson weather is brutal on exteriors. Salt air off the bay, southerly rain hammering one side of the house, summer sun bleaching the other. Mould and grime build up faster here than most of the country. We strip it back without wrecking your paint, your timber, or your roof.
One crew handles the whole exterior: houses, roofs, driveways, decks, gutters, fences, commercial buildings. One bill, one booking, no chasing three different tradesmen around Nelson.

After hundreds of jobs across the region, this is what actually gets your Nelson property looking tired, and what it costs you if you leave it.
- Salt-spray haze dulling paint on Tāhunanui and Atawhai homes
- Heavy black mould on south walls in The Wood and Washington Valley
- Lichen-covered roofs in the shaded streets up Britannia Heights
- Driveways tracked with red Maitai clay after winter rain
- Decks gone slick and green from the Maitai Valley damp
- Gutters blocked with autumn leaf-fall from Nelson's mature trees

Nelson water blasting: straight answers
How much does water blasting in Nelson cost?+
You get a fixed price in writing before we start, not a vague "competitive rate" that turns into a surprise on invoice day. Most full house washes in Nelson land between a few hundred and around a thousand dollars, depending on size, height and how much build-up there is. Ask us and you get it in writing.
Do you use soft wash or high pressure on Nelson homes?+
Soft wash for painted surfaces, roofs and anything fragile. High pressure for concrete, driveways and hard surfaces. Using the wrong one strips paint, wrecks roof coatings and forces water under your cladding. We pick the method that suits the surface, every time, not whatever's fastest for us.
How long until the mould comes back?+
On a straight wash, three to nine months in Nelson depending on shade and rainfall. Add a roof biocide treatment and you're looking at twelve months or more before it shows again. We tell you this upfront so you can plan the next clean instead of getting caught out.
Do you service all of Nelson?+
Yes, from the in-town streets to the lifestyle blocks on the edges. If a truck can get near it, we can clean it. No call-out fee anywhere inside the Nelson service area, and no getting bumped down the list because your job's "too small".
