Exterior: every 7–12 years (or sooner on the coast)
A quality exterior paint job on a well-maintained home should last between seven and twelve years under typical Sydney conditions. On the Northern Beaches — where salt air, UV, and coastal humidity are factors — that range often shifts to five to ten years for exposed surfaces.
This is a guideline, not a fixed rule. Some homes in exposed positions show signs of paint failure in four to five years. Others, particularly those on the sheltered western aspects, hold up for over a decade.
Signs your exterior needs repainting
Interior: every 7–10 years for most rooms
Interior paint generally lasts longer than exterior because it is not exposed to weather, UV, or moisture. Most rooms in an average home will look good for seven to ten years with quality paint and reasonable care.
High-traffic areas are the exception. Hallways, kitchens, and family rooms see more marks, scrubbing, and general wear. These areas often benefit from attention every five to seven years. Bathrooms and laundries, with their moisture exposure, should use a washable or semi-gloss finish and may need repainting earlier.
Northern Beaches note
The coastal environment on the Northern Beaches means exterior paint maintenance is more important — and more frequent — than in sheltered suburban areas. Letting exterior paint deteriorate too far means more extensive and expensive preparation work when the time comes to repaint.

Frequently Asked Questions
Run your hand along the surface. If it comes away with a chalky residue, the paint has oxidised and is beginning to fail. Visible cracking, peeling, or areas where paint is pulling away from the surface are clear signs of failure that need attention.
In most cases, you can repaint over existing paint — provided it is properly prepared. Loose and peeling paint must be removed. Surfaces must be cleaned, treated where needed, and primed where bare. Painting over poorly adhering paint is one of the most common causes of early paint failure.
Failed exterior paint exposes the substrate underneath — whether that is timber, render, masonry, or fibro — to moisture. This can lead to rot in timber, deterioration in render, and significant surface damage that is expensive to repair. Maintaining paint on time is far cheaper than remediation.
No. High-traffic areas — hallways, kitchens, bathrooms — typically need attention more frequently than low-traffic rooms like spare bedrooms. A professional painter can assess each area and advise on what genuinely needs doing versus what can wait.
