Most damaged aluminium doesn't need replacing. We repair it.
Installation scratches, coastal corrosion, impact dents, defect-list items before handover - we repair and colour-match the lot, on-site or in our Wairau workshop.
Operating since 2017. Two bases - Auckland HQ on the North Shore, and our Bay of Plenty branch. Fixed pricing per job. Crews that keep your programme moving, with finishes that blend into the original coating so the repair doesn't read as a repair.
Common Aluminium Damage We Repair
If it's aluminium and it's damaged, we can usually fix it without replacement. Roughly nine in ten jobs we assess come back as repairable. The work falls into a few common categories:
Installation scratches and scaffolding marks
The most common defect-list items on new builds. Repaired and colour-matched before handover.
Coastal corrosion and oxidation
Sea spray and salt air break down powder coating over time, particularly on ocean-facing joinery. We strip back the affected area, treat the substrate, and recoat.
Impact dents and break-in damage
Gates, doors, fences, and panels. We repair structural and cosmetic damage and refinish to match.
Powder coat chips, flaking, and colour fade
Common on older joinery and high-UV exposure. Often repairable in place.
Colour mismatches from prior repairs
Patchy touch-ups from earlier trades. We strip and recolour so the finish reads as one piece.
Defect-list and pre-handover items
Anything flagged at PCG or final inspection. We work to construction programmes and turn jobs around fast.

Every job runs through the same five stages, whether it's a single window frame or a full apartment block.
Assessment and colour match
We inspect the damage, photograph it, and identify the existing coating, whether powder coat, anodised, or wet-applied. Colour matching is done against the original substrate using physical samples and, on large jobs, manufacturer codes where available. Coatings are matched to AS/NZS 4506 powder coating standards.
Surface preparation
The damaged area is masked, sanded back, and cleaned. On powder-coated aluminium this means feathering the existing coating so the repair edge disappears. Substrate damage is filled and re-profiled at this stage.
Corrosion treatment
Where oxidation or salt corrosion is present, we treat the bare aluminium with an etch primer system before any topcoat goes on. This is the step that determines whether a coastal repair lasts.
Application
We use water-based Dulux coatings, applied by spray in our workshop or on-site depending on the job. Workshop application gives the cleanest finish on removable items. On-site application keeps fixed elements in place and the programme moving.
Cure and inspection
Full cure before reinstallation or sign-off. We inspect every job against the original coating and only call it done when the repair reads as one continuous finish.
Why Repair Instead of Replace
On most aluminium damage, repair costs a fraction of replacement and takes a fraction of the time. A scratched window unit might be quoted at $2,000+ to replace once you factor in the new joinery, removal of the existing unit, reinstallation, and sealing. The same damage, repaired in place, is usually a one-day job at a fixed price.
Programme impact is the bigger argument on live sites. Replacement units have lead times, sometimes weeks, sometimes months for non-stock colours or sizes. A repair crew on-site this week keeps your handover date intact. That's why most defect-list aluminium items end up with us rather than going back to the manufacturer.
The case for replacement is real when damage is structural, when the substrate is too far gone to refinish, or when the client wants a different product. We'll tell you when that's the call. The rest of the time, repair is the better answer.
| Repair | Replace | |
|---|---|---|
| Typical cost | Fixed price per job, usually a fraction of replacement | Full unit cost plus removal, install, and seal |
| Programme impact | Days, often on-site | Weeks to months, depending on lead time |
| Waste | Existing unit stays in service | Damaged unit to landfill |
| Finish | Colour-matched to surrounding coating | New unit, may not match aged adjacent joinery |
| When it's the right call | Cosmetic damage, corrosion, coating failure, dents | Structural damage, substrate failure, product change |
Recent Aluminium Repair Projects
A sample of recent aluminium remedials work across Auckland. Each project links through to a full case study.
Hurstmere Road, Takapuna
A complete joinery and ACM panel refurbishment for Madewell Construction at 87 Hurstmere Road. Premium Dulux coatings in Resene Rice Cake and Resene Thunderstorm transformed the building's exterior.

Almorah Rise Apartments
A full exterior joinery recoat and complete colour change at this Epsom apartment development. Working alongside MTD Builders, we used a high-pressure low-volume spray system for a sharp, uniform finish.

SPCA Hobsonville
Interior joinery repairs at the SPCA's Hobsonville facility - scratches, dents and surface damage from daily animal activity restored to a clean, consistent finish without full replacement, on a tight deadline with animals on-site.

Two bases, full coverage of both regions. Same crews, same process, same finishes across both.
Auckland
HQ and main workshop at 6/61 View Road, Wairau, on the North Shore. We work across Auckland on residential builds, commercial projects, and one-off jobs. Typical suburbs include:
If you're outside this list, ask. We cover the wider Auckland region.
Bay of Plenty
Our second base, with Jarrett leading work across the region. We take on residential and commercial projects from Tauranga through to the wider Bay.

What Builders and Homeowners Say
This whole team knows how to get your project done.
The finished repaint in fact is superior to the previous factory application. Our neighbours are so impressed that they have indicated they will use Recoat when their panels need a repaint.
Everyone we dealt with at Recoat was polite, professional and very helpful — we would recommend Recoat to anyone needing a professional outfit to recoat their joinery.
Careless tenants badly scratched a brand-new ranch slider but Recoat restored it to its former glory at a very reasonable cost. You'd never know anything had happened.
Aluminium Repair FAQs
-
Yes, in most cases. Scratches, dents, coastal corrosion, coating chips, and colour fade can all be repaired and recoated to match the original finish. The exceptions are structural damage to the aluminium itself, or substrate corrosion that's eaten through the metal - those usually need replacement. We assess every job and tell you straight which way it should go.
-
We match against the existing coating using physical samples and, on larger jobs, manufacturer colour codes where available. The match is then verified on a test panel before we apply to the actual repair area. The goal is a finish that reads as one continuous coating, not a patch.
-
Most repairs are completed in one to three days, depending on the scope and whether the work is on-site or in our workshop. A single scratched window unit is usually a same-day or next-day job. A full apartment recolour or a defect-list run across multiple units is scoped at quote stage with a fixed timeframe.
-
Both, depending on what makes sense for the job. Fixed elements like installed windows, doors, cladding, and gates are usually repaired on-site to avoid removal and reinstall costs. Removable items like cabinetry, handles, or unfixed panels often come back to our Wairau workshop for a controlled finish. We'll recommend the right approach when we quote.
-
We quote at fixed price after assessment. The cost depends on the type and extent of damage, the colour, the finish required, and whether the work is on-site or in-workshop. Repair is almost always a fraction of the cost of replacement once you factor in the new unit, removal, and reinstallation. Send through photos for an indicative quote.
-
Yes. Coastal corrosion is one of the most common jobs we do, particularly across Auckland's east coast and the Bay of Plenty. The repair involves stripping the affected area back to bare aluminium, treating the substrate with an etch primer system, and recoating. Done properly, the repair holds. Done as a touch-up over corrosion, it doesn't.
-
The colour is matched against the surrounding coating, the edge of the repair area is feathered into the original finish, and the coating is applied at the same gloss level as the existing surface. On most jobs the finish is indistinguishable from the original.
-
Yes. Defect-list aluminium remedials are a core part of what we do. We work to construction programmes, turn jobs around fast, and coordinate with site managers and project managers to keep the handover date intact. Most builds we work on have us back on-site multiple times across the project lifecycle.
