How often should I re-seal my Vancouver paver driveway?

Paver driveways in Metro Vancouver should be resealed every 3-5 years, with the specific timing depending on traffic levels, exposure conditions, and sealer quality. Vancouver's marine climate with over 1,200mm of annual rainfall and persistent humidity accelerates sealer breakdown compared to drier regions where sealers might last 5-7 years.

Climate factors that affect sealer longevity in Metro Vancouver include the constant moisture cycles from October through March, UV exposure during summer months, and the freeze-thaw cycles (though minimal compared to Eastern Canada). North-facing driveways and those shaded by large trees may need resealing more frequently due to moss and algae growth that breaks down the sealer film. Driveways with heavy vehicle traffic, oil stains, or salt exposure (near coastal areas in West Vancouver, North Vancouver, Richmond, or White Rock) will also require more frequent maintenance.

Signs your driveway needs resealing include water absorption rather than beading on the paver surface, visible staining that won't clean off, fading of enhanced colour from the previous sealer application, and moss or algae growth despite regular cleaning. If you can see efflorescence (white powdery residue) appearing on previously sealed pavers, the sealer has likely worn through. Joint sand erosion is another indicator — if polymeric sand is washing out of joints more frequently than every 3-4 years, sealing the surface will help protect the joint sand from rain erosion.

Proper resealing timing is critical in Vancouver's climate. Apply sealer only during dry weather windows between May and September, with at least 48 hours of no rain forecast after application. The pavers must be completely clean and dry before sealing — pressure wash to remove dirt, moss, and algae, allow 48-72 hours drying time, and replenish polymeric sand if needed before sealing. Never seal over wet pavers or during Vancouver's rainy season, as trapped moisture causes white hazing and sealer failure.

Professional vs. DIY sealing depends on driveway size and your comfort level. A typical 600 sq ft driveway requires 3-4 gallons of quality sealer ($200-400 in materials) plus sprayer rental and labour. Professional sealing runs $1,500-3,500 for the same driveway but includes proper cleaning, joint sand replenishment if needed, and warranty on the work. DIY sealing is feasible for homeowners with the right weather window and attention to surface preparation, but poor prep work or application during humid conditions leads to sealer failure within 1-2 years.

High-quality sealers last longer in Vancouver's challenging climate. Solvent-based sealers typically outperform water-based products in wet climates, though they're more expensive and have stronger odours during application. Budget sealers from big box stores often fail within 2-3 years in Metro Vancouver, while professional-grade products from manufacturers like SealMaster, Foundation Armor, or Techniseal can last 4-6 years with proper application.
