How much does it cost to fix pavers that were poorly installed by a previous contractor in Vancouver?

Repairing poorly installed pavers in Metro Vancouver typically costs $8-$25 per square foot, depending on the extent of the problems, but complete reinstallation often runs $15-$30 per square foot — sometimes making it more cost-effective to start over with proper base preparation.

The cost to fix botched interlock work depends entirely on what went wrong during the original installation. In Metro Vancouver's wet climate, most paver failures stem from inadequate base preparation, poor drainage design, or shortcuts that seemed fine initially but caused problems within 1-3 years. A qualified contractor needs to assess your specific situation to determine whether repair is feasible or if complete reinstallation is the better investment.

Common repair scenarios and costs include relevelling sunken or uneven areas ($10-$20 per square foot), which involves lifting pavers, correcting the base material, re-screeding bedding sand, and relaying pavers with fresh polymeric sand. If the base was too shallow or poorly compacted — the most common mistake in Metro Vancouver installations — you're looking at $15-$25 per square foot because the contractor must excavate deeper, add proper base material, compact in lifts, and essentially rebuild the foundation. Drainage problems that cause water pooling or base saturation require installing proper slope, adding drainage pipe, and potentially connecting to storm drains, adding $2,000-$5,000 to most repair projects.

Edge failures where pavers have spread or shifted due to missing edge restraints cost $8-$15 per linear foot to fix, including proper snap-edge installation and re-compacting affected areas. Joint sand washout from using regular sand instead of polymeric sand is relatively inexpensive to correct at $2-$4 per square foot — sweep out old sand, clean joints thoroughly, apply quality polymeric sand, and activate properly. However, if the sand washout allowed pavers to shift significantly, you're back to the $10-$20 per square foot range for relevelling work.

When complete reinstallation makes more sense: If the original contractor used insufficient base depth (common shortcut), skipped geotextile fabric on clay soil, or created drainage problems that affect your foundation or neighbouring properties, trying to patch the work often costs 70-80% of a complete reinstallation while delivering maybe 60% of the performance. A properly installed 400 square foot paver patio costs $6,000-$12,000 in Metro Vancouver, while attempting to repair a fundamentally flawed installation might cost $4,000-$8,000 and still leave you with a compromised result.

Metro Vancouver's climate makes proper repair critical because our 1,200mm+ annual rainfall exposes every drainage flaw and base deficiency. Water that pools beneath pavers during our October-to-March rainy season saturates clay subgrade, softens base material, and causes ongoing settling. Half-measures rarely work long-term in our wet conditions.

Get multiple assessments from experienced interlock contractors who can excavate a test section to examine the base depth, compaction quality, and drainage design. Many contractors offer free estimates, and seeing the actual base construction (not just the surface symptoms) is essential for accurate repair pricing. Document the problems with photos for insurance claims if the original work was recently completed and clearly defective.

Professional repair is essential for anything beyond simple relevelling of a few pavers. Proper base reconstruction, drainage correction, and edge restraint installation require plate compactors, laser levels, and experience with Metro Vancouver's soil conditions. DIY repairs on poorly installed pavers usually make the problems worse and void any remaining warranty from the original contractor.
