What's the cost to re-sand and re-seal an interlock driveway in Vancouver?

Re-sanding and re-sealing an interlock driveway in Metro Vancouver typically costs $3-$8 per square foot, or $1,500-$6,400 for a standard 500-800 sq ft driveway. The wide price range depends on the current condition of your pavers, whether polymeric sand replacement is needed, and the type of sealer selected.

Re-sanding costs $1.50-$3.50 per square foot and involves removing old, deteriorated joint sand, cleaning the joints thoroughly, applying new polymeric sand, and activating it with controlled water application. In Metro Vancouver's wet climate, polymeric sand typically needs replacement every 3-5 years as the constant rainfall gradually breaks down the polymer binding agents. If your driveway has significant moss growth in the joints, weed intrusion, or visibly empty joints, re-sanding is essential before sealing.

Sealing costs $1.50-$4.50 per square foot depending on the sealer type and surface preparation required. Basic acrylic sealers ($1.50-$2.50/sq ft) provide modest protection and color enhancement but need reapplication every 2-3 years. Premium urethane or polyurethane sealers ($3-$4.50/sq ft) offer superior durability, stain resistance, and typically last 5-7 years in Vancouver's climate. The sealing process includes pressure washing, allowing 48+ hours drying time (critical in Vancouver's humid conditions), applying sealer in thin, even coats, and maintaining traffic restrictions for 24-48 hours while curing.

Surface preparation significantly affects total cost. Driveways with heavy moss growth, oil stains, or efflorescence (white mineral deposits) require additional cleaning treatments that can add $0.50-$1.50 per square foot. Pressure washing alone costs $0.75-$1.25 per square foot, but moss treatment with iron sulphate, degreasing oil-stained areas, and efflorescence removal require specialized products and extra labor time.

Timing matters in Metro Vancouver's marine climate. The optimal window for re-sanding and sealing is May through October when you can count on 48-72 hours of dry weather for proper curing. Attempting this work during the October-to-March rainy season often results in poor polymeric sand activation, sealer application problems, and premature failure. Many contractors offer 10-15% discounts for off-season scheduling but will only proceed during confirmed dry weather windows.

DIY vs. professional considerations: Re-sanding is the most valuable DIY maintenance task homeowners can perform — quality polymeric sand costs $35-$50 per 50-pound bag (covers roughly 100 sq ft), and the process involves sweeping, cleaning joints, applying sand, and water activation. However, sealing requires professional equipment for even application, proper surface preparation, and experience timing the work with Vancouver's unpredictable weather. Poorly applied sealer creates a blotchy, peeling mess that's expensive to strip and redo.

Warning signs you need this maintenance: Empty or eroded joints, moss growing between pavers, weeds sprouting from joints, pavers shifting slightly when walked on, or a faded, weathered appearance. In Metro Vancouver's wet climate, delaying joint sand replacement allows water to penetrate the base material, potentially causing settling and requiring much more expensive releveling repairs ($8-$15 per square foot).

A typical maintenance schedule for Metro Vancouver driveways includes re-sanding every 3-5 years and sealing every 4-7 years depending on traffic, exposure, and sealer quality. Properties with heavy tree cover or north-facing exposure may need more frequent attention due to accelerated moss growth and reduced drying between rain events.
