How much does it cost to strip and reseal a paver driveway?

Stripping and resealing a paver driveway in Metro Vancouver typically costs $3-$8 per square foot, or $1,500-$6,400 for a standard 500-800 sq ft residential driveway. The wide price range depends on the current sealer condition, paver type, staining severity, and whether joint sand replenishment is needed.

Why Stripping is Often Necessary

Most paver sealers need removal every 3-5 years in Metro Vancouver's wet climate because they break down from constant moisture exposure, UV radiation, and thermal cycling. Old sealer that's peeling, hazing, or wearing unevenly creates a blotchy appearance that looks worse than unsealed pavers. Failed sealer also traps moisture and contaminants beneath the film, leading to efflorescence (white residue), dark staining, and moss growth that becomes increasingly difficult to clean.

Stripping involves applying a chemical sealer remover (usually methylene chloride or caustic-based), allowing it to soften the old sealer, then pressure washing at 2,500-3,500 PSI to remove the dissolved sealer film. This process typically requires 2-3 applications for complete removal, especially if multiple sealer coats were applied over the years. Professional stripping costs $1.50-$4 per square foot depending on how many sealer layers need removal.

Joint Sand Assessment and Replacement

Before resealing, contractors must evaluate the polymeric sand in the paver joints. Metro Vancouver's heavy rainfall often erodes joint sand over the same 3-5 year period that sealer degrades. If joints are more than 25% empty or if weeds and moss are growing through, the polymeric sand should be completely removed and replaced before sealing. Joint sand replacement adds $1-$2 per square foot to the project but is essential — sealing over compromised joints traps moisture and accelerates paver movement.

Surface Preparation and Cleaning

After stripping, the pavers need thorough cleaning to remove all sealer residue, efflorescence, oil stains, and organic growth. This involves degreasing (for oil stains common on driveways), efflorescence removal with muriatic acid solution, and moss/algae treatment. The surface must be completely clean and dry for 48+ hours before new sealer application. Poor surface prep is the leading cause of new sealer failure within the first year.

Resealing Process and Costs

New sealer application costs $1.50-$4 per square foot depending on sealer type and number of coats. Solvent-based sealers ($2-$4/sq ft) penetrate deeper and last longer in Vancouver's climate but require careful application and adequate ventilation. Water-based sealers ($1.50-$3/sq ft) are easier to apply and more environmentally friendly but may need more frequent reapplication. Most professionals apply two thin coats rather than one heavy coat for better durability and appearance.

Metro Vancouver Timing Considerations

Schedule stripping and resealing between May and October when you can guarantee 48-72 hours of dry weather after sealer application. Vancouver's rainy season (October through March) makes sealer application risky — rain within 24 hours of application can cause white hazing, poor adhesion, and uneven coverage that requires complete removal and reapplication.

When to Hire a Professional

Sealer stripping requires chemical handling, high-pressure equipment, and experience recognizing when old sealer is completely removed versus just loosened. DIY stripping often leaves sealer residue that prevents proper adhesion of new sealer. Professional contractors have commercial-grade strippers, appropriate pressure washing equipment, and disposal methods for chemical waste. For driveways over 300 square feet or sealers that have been reapplied multiple times, professional stripping and resealing is strongly recommended.

Cost Breakdown for a 600 sq ft Driveway:

• Sealer stripping: $900-$2,400


• Joint sand replacement (if needed): $600-$1,200


• Surface cleaning and prep: $300-$600


• New sealer application: $900-$2,400


• Total: $2,700-$6,600
