Should I expect my Vancouver paver colour to fade after 10 years?

Yes, some degree of colour change is normal and expected — but well-made concrete pavers in Metro Vancouver should retain most of their colour for 20+ years with basic maintenance.

The key distinction is between fading (pigment loss from UV exposure and weathering) and colour change from surface contamination — which is far more common in Metro Vancouver. Most homeowners who think their pavers have faded are actually looking at a combination of efflorescence residue, moss and algae staining, dirt accumulation, and oxidised sealer film. A thorough cleaning often reveals that the underlying paver colour is largely intact.

What Actually Causes Colour Change in Metro Vancouver

UV fading is real but modest in Vancouver's climate. Because Metro Vancouver receives significantly less intense sunlight than inland or southern regions — and because overcast skies dominate from October through March — UV-driven pigment degradation is slower here than in, say, the Okanagan or California. South-facing driveways and patios in full sun will show more fading than shaded north-facing installations. After 10 years, expect a 10-20% reduction in colour vibrancy on sun-exposed surfaces — noticeable if you compare a paver from under a planter to one in the open, but not dramatic.

Biological growth and staining is the dominant colour-change mechanism in Metro Vancouver, and it's driven entirely by the climate. Over 1,200mm of annual rainfall, persistent humidity in the 60-80% range, and mild temperatures create ideal conditions for moss, liverwort, algae, and lichen to colonise paver surfaces and joints — particularly on north-facing or shaded installations. This biological layer gives pavers a grey-green cast that reads as "faded" but is actually surface contamination sitting on top of the original colour. Oxygen bleach cleaner or a commercial paver cleaner (never chlorine bleach — it damages polymeric sand and discolours pavers) followed by pressure washing at 1,500-2,500 PSI typically restores significant colour.

Efflorescence — the white powdery calcium carbonate that leaches from cement — can persist on pavers for 1-3 years in Vancouver's wet climate, longer than in drier regions because the constant moisture keeps drawing minerals to the surface. It fades with weathering and can be removed with a diluted efflorescence cleaner.

Oxidised or peeling sealer is another culprit. Sealers applied too early (before efflorescence stopped), over damp pavers, or using low-quality products turn milky, yellow, or peel in Metro Vancouver's wet conditions — making pavers look dull and discoloured even though the paver itself is fine. Stripping old sealer and reapplying correctly restores the appearance.

How to Protect Colour Long-Term

A quality penetrating or film-forming sealer applied to clean, dry pavers (after waiting 6-12 months on new installations for efflorescence to stop) provides UV protection and makes the surface easier to clean. Reseal every 3-5 years in Metro Vancouver's climate. Replenish polymeric sand every 3-5 years to prevent moss from establishing in the joints — moss spreads from joints onto the paver surface over time.

Paver quality matters significantly. Premium concrete pavers from manufacturers like Techo-Bloc, Belgard, Unilock, or Mutual Materials use through-body colour pigments and high-density concrete mixes that resist fading far better than budget pavers with surface-applied colour. If your pavers were installed with quality product and proper base preparation, 10 years of Metro Vancouver weather should leave them looking quite good with routine maintenance.

If you're planning a new installation and longevity of appearance matters to you, ask your contractor about the specific paver manufacturer and product line — and get matched with an experienced installer through the Vancouver Construction Network at vancouverconstructionnetwork.com.
