"Will has now completed two projects for us. A carport rebuild and a large gazebo. Both have exceeded our expectations. We gave Will a basic concept and he pulled the job together for us. All completed to budget and we even added extras along the way. I highly recommend Will and his team for excellent workmanship and a quality job."

What's in Scope
Building Maintenance & Repair Work
Building Maintenance & Repair Work
We Handle Across Auckland
Cladding Repairs & Replacement
Damaged or moisture-affected cladding cut out and reinstated correctly. We work with timber weatherboard, fibre cement, and cavity-drained systems.
Rot Repairs
Timber rot behind cladding, around window joinery, in fascia boards, and under eaves - cut out, framing treated, reinstated with new timber. Not filler over the damage.
Leak Investigation & Repairs
We find the water entry point before we fix anything - roof-to-wall junctions, failed flashings, and penetrations around skylights and chimneys.
Metal Re-Roofing
New metal roofing installed over existing residential buildings, including ridges, valleys, and flashings.
Metal Flashings
New and replacement flashings around chimneys, skylights, vents, and roof-to-wall junctions. One of the most commonly deferred maintenance items on Auckland homes.
Gutter & Downpipe Replacement
Box gutters, fascia gutters, and spouting replaced or repositioned - often done alongside re-roofing or after a building inspection finds failed drainage.
Foundation Repairs
If maintenance has uncovered something larger, we can advise on whether the project is better handled as a house renovation or extension.
Worth Knowing
Why Auckland Buildings Deteriorate
Why Auckland Buildings Deteriorate
Faster Than Homeowners Expect
Auckland's mild, humid climate means significant year-round rainfall - particularly on the North Shore. Moisture management is the central challenge of building maintenance. It is slow, consistent, and easy to defer until it becomes expensive.
Older weatherboard homes across Birkenhead, Northcote, Devonport, and Glenfield were built before modern cavity cladding systems existed. Direct-fixed timber holds moisture against the framing. Rot starts from the inside out - by the time it's visible from the street, it's usually been building for years.
Getting maintenance done early costs a fraction of what structural repair costs once the framing is involved.
How It Works
How We Scope and Complete
How We Scope and Complete
Building Maintenance Work
Site Inspection & Scope
We visit and inspect the building - roof, gutters, cladding, joinery, any signs of water ingress or structural movement. We write up what we found, what's causing it, and what needs to happen. We do not quote from photos or descriptions.
Written Quote & Scheduling
A fixed price or estimated range tied to the specific scope. If additional damage might be found behind the surface, we state that upfront before you commit. Scheduling confirmed in writing before the job starts.
Work, Reinstatement & Sign-Off
Repairs completed and all openings left weathertight before we leave. We walk through the completed work with you before signing off. Where Restricted Building Work was carried out, you receive a Record of Work tied to the property address.

When Building Maintenance Work
When Building Maintenance Work
Requires a Licensed Builder in New Zealand
Not every maintenance job requires an LBP - but more of them do than homeowners realise.
Work in these categories carried out by an unlicensed person cannot be assigned a Record of Work, creates complications at Council inspection, and can void insurance coverage or create disclosure obligations at future property sale.
Will Tangohau is a Licensed Building Practitioner (LBP) and NZCB member. Every maintenance job that falls within Restricted Building Work is documented with a Record of Work tied to the property address.

- Cladding replacement on any external wall
- Structural repairs to framing or foundations
- Re-roofing (including all associated flashings)
- Any repair work that requires a building consent
Work in these categories requires LBP supervision - regardless of the scale of the job.

Common Questions

Building Maintenance & Repairs
Questions - Auckland
How much does building maintenance work cost in Auckland?
Every job is quoted after a site inspection - cost depends on what's found, the type of repair needed, whether scaffolding is required, and the materials involved. The site visit is free and the written quote commits us to a scope and price.
How do I know if I have rot or cladding damage?
Early indicators include paint bubbling or peeling on exterior walls, weatherboards that feel soft or spongy, water staining inside around window frames, or a damp smell in rooms sharing an external wall. By the time rot is obvious from outside, it has usually gone further into the framing than is visible.
Do you handle work required for insurance purposes?
We can scope and quote repair work required for insurance compliance, provide Records of Work where Restricted Building Work is involved, and supply dated before-and-after photos.
