How much does it cost to strip old failed sealer and start fresh on pavers in Vancouver?

Stripping failed paver sealer and resealing typically costs $4-$8 per square foot in Metro Vancouver, making it one of the more expensive paver maintenance procedures. For a standard 400 sq ft patio, expect to pay $1,600-$3,200 for professional sealer removal and fresh application.

Why Sealer Stripping Is Expensive

Failed sealer removal is labour-intensive because it requires chemical strippers, multiple applications, pressure washing, and complete drying before new sealer can be applied. The process typically takes 2-3 days depending on weather conditions and the type of failed sealer. In Metro Vancouver's humid climate, drying time between steps is extended, which adds to labour costs.

The most common sealer failures requiring stripping include white hazing (caused by sealing over moisture or efflorescence), peeling and flaking (from poor surface preparation), and blotchy appearance (from sealing over dirty pavers or improperly cured polymeric sand). Film-forming sealers like acrylics are particularly prone to these issues in Vancouver's wet climate and are the most difficult to remove.

The Stripping Process

Professional sealer removal starts with chemical strippers specifically designed for the type of sealer being removed. Acrylic sealers require different strippers than penetrating sealers. The stripper is applied, allowed to dwell for the specified time, then agitated with brushes or surface cleaners. Multiple applications are often needed for thick or aged sealer buildup.

After chemical stripping, the surface is pressure washed to remove loosened sealer and stripper residue. The pavers must then dry completely - typically 48-72 hours in Metro Vancouver's humid conditions - before new sealer can be applied. Any remaining polymeric sand that was damaged during stripping must be removed and replaced before sealing.

Cost Breakdown for Metro Vancouver

• Chemical stripping labour: $2-$4 per sq ft
• Pressure washing and cleanup: $1-$2 per sq ft
• Joint sand replacement (if needed): $0.50-$1 per sq ft
• New sealer application: $1.50-$3 per sq ft
• Total project cost: $1,600-$3,200 for 400 sq ft

Difficult access, heavily textured pavers, or multiple coats of old sealer can push costs to the higher end. Properties in West Vancouver, North Vancouver, or other areas requiring difficult material transport add $200-$500 to the total.

When to Strip vs. Alternative Solutions

Sealer stripping is only necessary when the existing sealer has failed catastrophically - white hazing, peeling, or severe discoloration. Minor wear or fading can often be addressed by cleaning and applying a compatible topcoat. However, trying to seal over failed sealer typically makes the problem worse and more expensive to fix later.

Preventing Future Sealer Problems

The best prevention is proper initial application - clean, dry pavers with fully cured polymeric sand, applied during dry weather with proper coverage rates. In Metro Vancouver, wait 6-12 months after new paver installation before sealing to allow efflorescence to stop naturally.

When to Hire a Professional

Sealer stripping requires chemical knowledge, proper safety equipment, and experience with different sealer types. The chemicals used are caustic and can damage surrounding vegetation or concrete if mishandled. Professional contractors have the right strippers, pressure washing equipment, and experience to complete the job safely without damaging the pavers underneath.
