Washing grey weathered cedar deck boards at a home in Nanaimo BC

Nanaimo Deck Washing

Nanaimo gets a genuinely dry July and August and a wet six months either side of them, and a deck registers both. One end of the same set of boards can be greening in shade while the other is bleaching in sun, which is two conditions and one job.

Local Conditions in Nanaimo

Green All Winter, Bleached All Summer

Nanaimo gets a real dry summer and a wet six months either side of it, and a deck registers both. Winter leaves the shaded end green and slick; summer then bleaches and opens the grain on the exposed end, and the two want different handling on the same set of boards. Exposure decides which problem dominates. The harbour is sheltered behind Newcastle and Protection Islands, but the shoreline north of Departure Bay faces the Strait of Georgia directly — the stretch the city’s own Rocky Point, Hammond Bay and Stephenson Point plan covers. Decks along it carry salt, which does not come off in a rinse and keeps drawing moisture back into timber that looks dry. Cedar and older pressure-treated fir both need to come clean at a pressure well under what the concrete beside them will take.

  • Winters mild and damp rather than frozen, so moss and algae never get knocked back

Commonly Asked

Once a year is enough almost nowhere in Nanaimo, and the reason is the mix of trees rather than the amount of rain. If your lot has fir or cedar on it, needles come down all year and heaviest through August and September, so the gutters are part full before the deciduous drop even starts. Clean once in October and you catch the needles and miss the leaves; clean once in December and the needles sat there all autumn. Twice is the honest answer for a treed lot. Once is genuinely fine for an open lot in the north end with nothing overhanging it.
