Richmond’s coastal humidity and flat terrain create conditions that accelerate paint failure faster than most BC cities. Moisture has nowhere to drain, and homes are constantly exposed to salt-laden air from the Fraser River delta. Here are 6 signs your Richmond home needs attention — before small problems become expensive repairs.
- Peeling and bubbling paint in Richmond is almost always moisture-related.
- Stucco cracking is a serious warning sign that requires immediate attention.
- Mould and mildew on exterior surfaces is common in Richmond and must be treated before repainting.
- Caulking failures around windows and doors are the primary entry point for water damage.
- Richmond homes typically need repainting every 6–9 years due to coastal humidity.
1. Peeling or Bubbling Paint
Peeling or bubbling paint is the most visible sign of moisture intrusion. In Richmond, this is extremely common on west and south-facing walls that receive direct rain. Once the paint film breaks, water enters the substrate and the damage accelerates quickly.
2. Stucco Cracking
Hairline cracks in stucco are normal, but cracks wider than 1/8 inch are a serious concern. They allow water to enter the wall cavity, leading to mould, rot, and structural damage. Stucco cracks must be filled and sealed before any repainting.
3. Mould and Mildew Growth
Dark staining or green patches on painted surfaces are signs of mould or mildew. This is extremely common in Richmond, particularly on north-facing walls and under overhangs. Mould must be treated with a biocide wash before repainting — painting over it will not stop it from returning.
4. Fading and Chalking
If your paint colour has faded significantly or leaves a chalky residue when touched, the UV-protective properties of the coating have been depleted. The surface is now absorbing moisture rather than repelling it.
5. Caulking Failures
Cracked or missing caulking around windows, doors, and trim is the primary entry point for water in Richmond homes. This is especially common around older aluminum-framed windows. Recaulking is always included in a proper exterior repaint.
6. It Has Been More Than 7 Years
In Richmond’s climate, even premium exterior paint begins to lose its protective properties after 7–8 years. If it has been longer than that, a professional inspection is warranted even if the paint looks acceptable from the street.
Frequently Asked Questions
How often should I repaint my house exterior in Richmond?
With Sherwin-Williams Duration or SuperPaint, most Richmond homes need repainting every 7–9 years. Stucco homes or those with significant moisture exposure may need attention at 6–7 years.
Can I paint over mould on my Richmond home?
No. Mould must be treated with a biocide wash and the moisture source addressed before any painting begins. Painting over mould will result in it returning through the new paint within months.
