Keep your development
compliant, clean,
and covered.
Most insurers require annual exterior maintenance to keep biological growth under control. We provide that service — reliably, documented, and on schedule — so your building stays covered and presentable year-round.

Biological growth isn't
just cosmetic. It's a
coverage risk.
When insurers assess a claim involving weather damage, leaks, or structural deterioration — one of the first things they examine is whether the building was being maintained. Uncontrolled biological growth is a red flag that often results in declined or reduced claims.
Many commercial and residential development policies contain maintenance clauses that require annual exterior cleaning. Failure to document this can void a claim — even when the damage itself was weather-related.
Moss & Lichen
The most structurally damaging biological growth on NZ buildings. Lichen embeds rootlets into concrete, paint, and roofing materials — physically breaking down the surface over time. Moss retains moisture against cladding, accelerating rot and corrosion beneath the surface.
Algae & Biological Film
Green and black algae form a slick biological film across exterior walls, paths, driveways, and roofing. On walkways, this creates a documented slip hazard and liability exposure. On walls and roofing, it traps moisture and degrades paint adhesion and surface integrity.
Mould & Mildew
Common on shaded elevations and under eaves in Auckland's humid climate. Left untreated, mould spreads into building cavities, wall linings, and insulation. Beyond the structural concern, mould presence in a building is a health and habitability issue that affects tenants and liability.
A full annual clean —
everything documented.
Our annual development clean covers every surface that matters for insurance compliance and building presentation. You receive a written service record after every visit — ready to attach to any policy renewal or claim documentation.
Exterior Softwash
Full exterior wall clean — biological growth removed from cladding, weatherboards, brick, concrete, and plaster. Low-pressure, surface-safe technique that won't damage paint or seals.
Roof Treatment
Moss and lichen treated at the root and cleared from all roof surfaces. Applies to concrete tile, metal, and colorsteel roofing. Treatment residue continues working after the visit.
Gutter Clean & Flush
All gutters cleared of debris and downpipes flushed to confirm free flow. Blocked guttering is one of the most frequently cited maintenance failures in weather-related claims.
Driveway & Path Clean
Common area driveways, carparks, footpaths, and entry zones cleaned of algae, mould, and organic staining. Eliminates slip hazards and improves overall site presentation.
Window & Entry Glass
Ground-floor and accessible glazing, entry doors, and frames cleaned. Removes salt residue, hard water staining, and biological film that builds up on coastal and urban sites.
Documented Service Record
A written report issued after every visit covering dates, scope of work, surfaces treated, and any issues noted on site. Formatted for insurer and body corporate records.
The growth timeline —
and what it costs.
Biological growth on an unmaintained development doesn't stay still. Here's how it typically progresses — and what it means for your compliance and coverage.
Built for the people
who manage developments.
Whether you're managing a single block or a portfolio of sites, we set up a programme that runs on schedule and keeps every property documented and compliant.
Body Corporates
Multi-unit residential developments with shared exterior maintenance obligations. We handle the scheduling, servicing, and documentation — giving the body corporate a reliable annual maintenance record for insurance and AGM reporting.
Annual programmeProperty Developers
New developments requiring pre-handover cleans and post-completion maintenance programmes. We remove construction residue, staining, and any early biological growth before the building is presented to buyers or tenants.
Pre-handover & ongoingFacilities & Asset Managers
Portfolio managers overseeing multiple sites who need a consistent, documented service across all properties. One point of contact, one schedule, and individual service records per site — ready for audits, insurance renewals, and compliance reporting.
Portfolio programmesReliable service.
Records you can use.
Written service records every visit
Every clean comes with a dated, scoped service record. Covers what was done, what surfaces were treated, and anything flagged on site. Ready to attach to any insurer request or body corporate file.
Annual schedule — set and forget
We set up the programme once and manage the scheduling from there. You'll receive reminders before each visit and records after. No chasing, no missed years, no gaps in your compliance history.
Fully insured for commercial sites
We carry commercial-grade public liability insurance appropriate for body corporate and multi-unit residential developments. Documented cover available on request.
On-site issue flagging
If we spot something that needs attention — cracked cladding, blocked downpipes, early roof damage — it goes in the service report. You stay ahead of problems before they become claims.
Local, Hibiscus Coast based
Based in Red Beach. We know the Hibiscus Coast climate — the salt air, the humidity, the shade exposure. We understand what drives biological growth here and how to stay ahead of it.

development on the books.
Tell us about the property — number of buildings, site type, and when it was last cleaned. We'll put together a compliance programme and pricing that works for your portfolio.
