How Often Should You Repaint Your Home's Exterior?

It is one of the most common questions we get on an estimate. The short answer is that most Lower Mainland homes need an exterior repaint every 5 to 10 years. The longer answer depends on what your home is made of, how much weather it takes, and how well the last coat was done.

Out here on the West Coast, our climate is the biggest factor. All that rain, salt air, and shade is harder on paint than the dry summers you see in the Interior. Here is how to think about timing so you repaint before the weather starts costing you.

Typical repaint intervals by material

Every home is different, but these are the general windows we see hold true across the Lower Mainland:

• Wood and cedar siding: roughly every 3 to 7 years. Natural wood drinks up moisture and moves with the seasons, so it is the most demanding surface to keep sealed.
• Stucco: roughly every 5 to 10 years. It holds paint well, though hairline cracks and our constant damp can shorten that window.
• Fibre cement (like Hardie board): often 10 to 15 years. It is stable and weather-resistant, so a quality coat tends to go the distance.
• Trim, doors, and fascia: these take the most direct sun and rain and usually need attention before the main walls do.

Why our West Coast climate speeds things up

Paint is your home's raincoat, and ours gets a real workout. Months of steady rain push moisture into any gap in the finish. North-facing walls and shaded sides stay damp longer, which is exactly where we tend to find moss, mildew, and early peeling. Add big swings between wet winters and bright summers, and the paint film expands and contracts until it starts to give out.

If your home sits under tall trees, near the water, or in a low spot that rarely fully dries, plan to be on the shorter end of those ranges.

The warning signs it is time

You do not have to count the years. Your home will tell you. Walk the exterior on a dry day and look for:

• Fading or chalkiness: colour looking washed out, or a powdery residue on your hand when you rub the siding.
• Cracking, flaking, or peeling: the clearest sign the film has failed and water is getting behind it.
• Exposed or greying wood: bare patches where the paint has worn through, which is an open door for rot.
• Failing caulk: gaps and cracks around windows, doors, and trim where the seal has pulled away.
• Moss, mildew, or dark streaks: common on the shaded sides and a hint the surface is staying too wet.

Spot a few of these and it is worth getting ahead of it. Repainting while the surface is still sound is far cheaper than repairing water-damaged wood later.

Good prep and quality paint buy you years

Here is the part most people do not see. The biggest reason one paint job lasts twelve years and another fails in four is not the brand on the can, it is the prep underneath. Proper washing, scraping, sanding, priming bare spots, and fresh caulking give the new coat something solid to grip. Skip that and even premium paint peels early.

Pair careful prep with a quality exterior product rated for our wet climate and you push your repaint interval toward the long end of every range above. That is exactly how we approach every exterior we take on.
