How often should a commercial building exterior be repainted in Vancouver's climate?

In Metro Vancouver's wet coastal climate, commercial building exteriors typically need repainting every 7 to 10 years, though some exposures can shorten that timeline considerably. South- and west-facing walls that take the brunt of rain and UV exposure may need attention as early as 5 to 7 years, while sheltered north-facing walls can sometimes go 12 years or more.

Vancouver's combination of heavy rainfall, mild temperatures, and limited freezing creates specific challenges. Moisture penetration is the primary enemy — if paint starts peeling or bubbling, water is getting behind the coating and can cause wood rot, stucco delamination, or mould growth. Catching early signs of paint failure and addressing them promptly is far cheaper than dealing with substrate damage.

The type of exterior material affects repainting frequency. Stucco and concrete — common on commercial buildings in areas like Mount Pleasant, Main Street, and East Vancouver — hold paint well but are prone to hairline cracking that allows moisture in. Wood siding on older commercial buildings requires more frequent maintenance. Metal cladding and composite panels on newer buildings in the Olympic Village or River District need specialized coatings but generally last longer between repaints.

A quality exterior paint job using premium acrylic elastomeric coatings can extend your repaint cycle by two to three years compared to standard exterior latex. These flexible coatings bridge small cracks and shed water more effectively — a worthwhile investment given Vancouver's rainfall averaging over 1,100 millimetres annually.

Schedule an exterior inspection with a commercial painter every three to four years to catch problem areas before they require a full repaint.
