How much does it cost to seal interlock pavers in Vancouver?

Paver sealing in Metro Vancouver typically costs $3-$7 per square foot, with most residential projects ranging from $1,500-$3,500 for a standard 500 sq ft area. This includes professional cleaning, joint sand replenishment if needed, and application of a two-coat sealer system.

The total cost depends on several factors specific to your installation. Surface preparation is the largest variable — if your pavers need deep cleaning to remove moss, algae, or oil stains (common in Vancouver's humid climate), expect to pay toward the higher end of the range. Properties with significant moss growth, which is extremely common on north-facing installations and shaded areas in Metro Vancouver, require additional cleaning time and specialized treatments before sealing.

Joint sand condition significantly affects pricing. If your polymeric sand has washed out or degraded — a frequent issue in Vancouver's heavy rainfall climate — contractors need to remove old sand, clean joints thoroughly, and apply fresh polymeric sand before sealing. This joint sand restoration adds $1-$2 per square foot to the project but is essential for proper sealer performance. Sealing over empty or compromised joints traps moisture and leads to sealer failure within 1-2 years.

Metro Vancouver's marine climate creates unique sealing challenges that affect both timing and cost. The persistent moisture and humidity mean pavers must be completely dry for 48 hours minimum before sealer application, and contractors need a weather window of at least 24 hours after application with no rain forecast. This limits the sealing season to roughly May through September, creating higher demand and pricing during these months. Many contractors charge premium rates for sealing work scheduled during the optimal summer window.

Material quality varies dramatically in price and performance. Budget acrylic sealers cost $0.50-$1.00 per square foot in materials but typically last only 2-3 years in Vancouver's wet conditions before requiring reapplication. Premium penetrating sealers or hybrid systems cost $1.50-$3.00 per square foot in materials but provide 5-7 years of protection and better resistance to Vancouver's frequent rain, moss growth, and UV exposure from summer sun.

Professional cleaning and preparation typically accounts for 40-60% of the total sealing cost. This includes pressure washing at appropriate PSI levels (1,500-2,500 PSI to avoid surface damage), treating moss and algae growth with specialized cleaners, removing efflorescence or staining, and ensuring complete drying. Contractors experienced with Vancouver's climate understand that rushing the preparation phase leads to sealer adhesion problems and premature failure.

When to hire a professional for sealing: Any installation larger than 200 square feet, areas with significant moss or staining, or pavers that haven't been sealed in 5+ years should be professionally sealed. The specialized equipment for proper surface preparation, knowledge of sealer compatibility with different paver types, and experience with Vancouver's climate conditions make professional sealing a worthwhile investment for most homeowners.

DIY sealing is possible for small, clean installations if you have 3-4 consecutive dry days and the pavers are already in good condition with intact joint sand. However, improper surface preparation or sealer application in Vancouver's challenging climate often creates problems that cost more to fix than professional sealing would have cost initially.
