How to tell when your home needs repainting or restaining
In New Zealand, homes face a mix of sun, wind, rain, and humidity that gradually wears down exterior finishes. Whether your cladding is painted weatherboard, stained timber, plaster, or brick, it pays to know the signs that your home might need a refresh.
Here’s what to look for:
1. Fading or Uneven Colour
Strong UV exposure breaks down both paint and stain over time. If your surfaces are looking patchy, chalky, or dull, the finish may no longer be offering full protection.
2. Peeling, Cracking or Flaking
This is more common with paint but can happen with stain too—especially if the surface wasn’t prepared well or the weather has been rough. Once coatings start breaking down, moisture can get in.
3. Mould, Mildew or Black Streaks
You’ll often see this on shaded areas or around downpipes. If it returns soon after cleaning, it’s likely the surface needs resealing.
4. Bare Timber or Water Staining
On stained homes, if the wood looks dry, patchy, or absorbs water instead of repelling it, the stain is no longer doing its job. This can lead to greying or water damage over time.
5. Surface Movement or Damage
With timber trims or weatherboards, gaps and cracks can appear as wood expands and contracts. If these areas aren’t sealed properly, they become weak spots.
6. It’s Been a While
Painted surfaces typically last 7–10 years, while stain may need refreshing every 3–5 years depending on the product and exposure. If you're unsure when it was last done, a quick inspection can help.
Tips to extend the life of your paint or stain
Wash Yearly: A light soft wash removes dust, mould, and salt buildup.
Keep Plants Trimmed Back: Reduces moisture and surface abrasion.
Repair Quickly: Touch up small chips, cracks, or worn patches early.
Monitor High-Stress Areas: Windowsills, bargeboards, and sun-exposed walls wear faster and may need attention sooner.
With regular care, your home’s finish can keep protecting and looking great for years—whether it’s painted, stained, or a bit of both.
