Why Blenheim homes call us first
Water blasting Blenheim. Wine-country homes, vineyard cottages, town houses and the big long driveways they all sit on.
Blenheim is dry and dusty half the year, then damp enough in winter to grow moss on anything shaded. Vineyard properties get spray drift and clay dust on the cladding. We handle the full exterior in one visit so you're not chasing three different tradies.
One crew handles the whole exterior: houses, roofs, driveways, decks, gutters, fences, commercial buildings. One bill, one booking, no chasing three different tradesmen around Blenheim.

Blenheim water blasting: straight answers
How much does water blasting in Blenheim 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 Blenheim 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 Blenheim 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 Blenheim 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 Blenheim?+
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 Blenheim service area, and no getting bumped down the list because your job's "too small".
