What's the price per square foot for interlock sealing in Metro Vancouver?

Interlock sealing in Metro Vancouver typically costs $3-$7 per square foot, with most residential projects falling in the $4-$5 range. For a standard 400 sq ft patio, expect to pay $1,600-$2,800 for professional sealing including surface preparation, cleaning, and two-coat application.

The wide price range reflects several factors that significantly impact sealing costs in Metro Vancouver's climate. Surface preparation is the most labour-intensive component — pavers must be thoroughly cleaned of moss, algae, dirt, and efflorescence before sealing. In Vancouver's humid climate, moss growth on north-facing or shaded installations requires pressure washing, chemical treatment, and sometimes manual scraping, which can add $1-$2 per square foot to the base sealing price.

Joint sand condition heavily influences pricing. If polymeric sand joints are eroded, missing, or contaminated with organic growth (common after 3-5 years in Metro Vancouver), contractors must remove old sand, clean joints, apply new polymeric sand, and allow it to cure before sealing. This joint restoration adds $1.50-$3.00 per square foot but is essential — sealing over compromised joints traps moisture and debris, leading to premature sealer failure.

Premium sealers cost more but perform better in Vancouver's wet climate. Solvent-based sealers ($5-$7 per sq ft) penetrate deeper and resist Vancouver's persistent moisture better than water-based sealers ($3-$4 per sq ft). High-quality sealers from manufacturers like SealMaster, Foundation Armor, or Techniseal last 3-5 years in Metro Vancouver conditions, while budget sealers may fail within 18-24 months due to the region's heavy rainfall and UV exposure.

Timing affects both price and performance. Sealing requires 48+ hours of dry weather for proper curing, making the May-to-September window optimal in Metro Vancouver. Contractors often charge premium rates ($6-$8 per sq ft) for sealing during brief dry periods in fall or winter. Never seal wet pavers or during Vancouver's rainy season — trapped moisture causes white hazing, peeling, and complete sealer failure.

Additional cost factors include: difficult access (narrow side yards common in Vancouver neighbourhoods add $0.50-$1.50 per sq ft), efflorescence removal on newer pavers ($1-$2 per sq ft), and stain treatment for oil, rust, or organic stains ($2-$4 per sq ft for spot treatment).

DIY sealing is possible for experienced homeowners but requires proper equipment (pressure washer, surface cleaner, pump sprayer or roller) and perfect weather timing. Professional sealing includes warranty coverage (typically 2-3 years) and expertise in surface preparation that determines long-term performance.

When to hire a professional: Any installation over 300 sq ft, pavers with significant moss or staining, or if joint sand needs replacement. Professionals have commercial-grade cleaning equipment and experience timing sealer application between Vancouver's frequent rain events.
