The paint on the south side of my house is fading way faster than the rest — what can I do about it?

South-facing walls in Metro Vancouver take a beating from UV exposure, especially during our long summer days when we get up to 16 hours of sunlight. It's the most common paint complaint we hear from homeowners across the region, from Surrey to North Vancouver.

The fading happens because UV radiation breaks down the pigment binders in paint. Darker colours like deep reds, blues, and greens fade the fastest, while lighter tones hold up much longer. If your south wall is a bold colour, expect it to show fading within three to five years even with quality paint.

For your next repaint, choose a premium exterior paint rated for UV resistance — look for products with ceramic microsphere technology or high-quality acrylic resins. Expect to pay $65 to $85 per gallon for top-tier exterior paint, but the extra cost pays for itself with several more years of colour retention. Flat and matte finishes also show fading less than satin or semi-gloss because they scatter light differently.

Colour selection makes a big difference. Earth tones, warm greys, and muted greens resist visible fading far better than saturated hues. If you love bold colour, consider using it on your front door or accent trim where touch-ups are easier.

Another option is applying a clear UV-protective topcoat over your paint. These add roughly $1.50 to $2.50 per square foot to the project cost but can extend the life of the colour significantly.

As a practical next step, get a professional colour consultation — a good painter can recommend specific UV-resistant products and colours that will hold up on your south-facing exposure while still achieving the look you want.
