Exterior House Painting Island Bay Wellington

Island Bay's 1920s villas and bungalows sit directly in the path of Cook Strait weather — salt air, strong southerlies, and occasional sea spray make this one of the harshest painting environments in Wellington. Coastal exposure shortens the life of any exterior paint system, and cutting costs on preparation or product quality here is a short-term decision with an expensive consequence.

Why Island Bay Homeowners Choose Our Exterior Painting

Coastal Salt and Corrosion Management

Salt air deposits on exterior surfaces accelerate paint breakdown and corrode metal fixings, flashings, and hardware. Before any painting starts, we wash all surfaces thoroughly to remove salt contamination — pressure washing alone isn't enough on surfaces within direct spray range. We also treat rust on exposed fixings and recommend stainless or galvanised replacements where standard fixings are already failing. Using paints with salt-resistant formulations isn't optional this close to the coast.

Coastal-Grade Paint Specification

Not all exterior paints are equal in a coastal environment. We specify Resene systems from their marine and high-exposure range for Island Bay properties — products engineered for UV resistance, salt tolerance, and flexibility under thermal movement. The extra cost per litre is marginal compared to the additional years of service life you get in a corrosive coastal environment.

Understanding the Repaint Cycle

In Island Bay, expect to repaint every 8–10 years with quality products and preparation — shorter than sheltered suburbs but achievable with the right system. We'll give you an honest assessment of your current paint condition and tell you whether you need a full repaint or whether targeted maintenance and spot work will extend the life of what's there.

Our Exterior Painting Process

We follow a consistent six-step process on every coastal job:

• Site assessment — inspect for salt contamination, rust, substrate condition, and access requirements
• Surface preparation — salt wash, pressure wash, scrape, sand, treat rust, prime bare surfaces
• Masking and protection — tape windows, cover gardens and hard surfaces
• Prime coat — corrosion-inhibiting primer on metal elements, appropriate primer on timber
• Two finish coats — coastal-grade paint applied to full film thickness
• Final inspection and touch-up — walk-through with you before we leave site

What Our Service Includes

• Salt contamination wash and full surface preparation
• Two coats of premium coastal-grade exterior paint
• Window frames, fascias, soffits, and bargeboards
• Corrosion treatment on exposed metal elements
• Doors and exterior joinery included in scope
• All masking, protection, and clean-up
• Registered Master Painters workmanship guarantee

Cost Guide

Exterior painting costs depend on house size, substrate condition, and coastal preparation requirements. As a guide for the Wellington market:

• Small home (under 120m²): $8,000–$15,000
• Medium home (120–200m²): $15,000–$25,000
• Large home (200m²+): $25,000–$45,000

Coastal properties with significant rust treatment or corrosion repair work will sit toward the higher end. Get a free on-site quote for a price specific to your property.

FAQs

How often does exterior paint fail in a coastal suburb?

Without the right preparation and paint specification, you can see failure within 4–5 years in a direct coastal environment. With quality prep and coastal-grade products, 8–10 years is a realistic expectation. Properties further from the foreshore — on Clyde Street versus the Esplanade — will see meaningfully longer paint life.

My paint is blistering and peeling — what causes that near the coast?

Blistering is almost always a moisture or adhesion issue. Salt contamination under the paint film traps moisture, which expands under heat and lifts the coating. This is why surface washing before painting is non-negotiable on coastal properties — painting over salt contamination guarantees early failure.

Do you treat rust on flashings and fixings?

Yes. We treat surface rust with a rust converter or mechanical preparation depending on severity, and prime with a corrosion-inhibiting product. Where fixings or flashings are beyond treatment, we'll flag this in the quote — replacing a rusted flashing before painting is far cheaper than dealing with the water damage it causes later.

Can I choose a lighter colour to reduce UV bleaching?

Lighter colours do fade less visibly than dark ones in high-UV environments, but the more significant factor is paint quality and film thickness. We'll walk you through colour options and the performance characteristics of different sheens and formulations so you can make an informed choice.
