How much does it cost to fix heaved pavers from tree roots?

Repairing heaved pavers from tree root intrusion typically costs $15-$35 per square foot in Metro Vancouver, depending on the extent of root damage and whether the tree remains. For a typical 100-200 square foot affected area, expect to pay $1,500-$7,000 for professional repair.

The cost varies significantly based on the repair approach required. Minor heaving affecting 50-100 square feet where roots haven't completely destroyed the base runs $1,500-$3,500. This involves lifting the affected pavers, cutting protruding roots, adding new bedding sand, and relaying the pavers. Major root damage requiring base reconstruction costs $25-$35 per square foot because the contractor must excavate deeper, remove root-contaminated base material, install root barriers, rebuild the base with fresh gravel, and reinstall pavers with new polymeric sand.

Tree removal versus preservation dramatically affects repair costs. If you're keeping the tree, root barriers (solid HDPE sheets installed vertically in the soil) add $8-$15 per linear foot to deflect future root growth away from the paver area. However, cutting major structural roots can destabilize or kill the tree, especially mature maples, cedars, and Douglas firs common in Metro Vancouver. An arborist consultation ($200-$400) helps determine which roots can be safely cut. If the tree must be removed, add $1,500-$5,000+ for professional tree removal, but this eliminates future root problems permanently.

Metro Vancouver's wet climate complicates root repairs because disturbed soil around cut roots becomes saturated during our October-to-March rainy season. Proper drainage design becomes even more critical when the natural root system that helped manage water is disrupted. Many contractors recommend upgrading to a deeper base (8-10 inches instead of the original 6 inches) and installing perforated drain pipe in root-damaged areas to prevent future water-related settling.

Prevention costs less than repair. Root barriers installed during original paver installation cost $8-$12 per linear foot. Large trees within 3-5 metres of interlock installations will eventually cause heaving - it's not a matter of if, but when. Maples are particularly aggressive, with surface roots that can lift pavers within 5-7 years of installation.

DIY root repair is not recommended for areas larger than 20-30 square feet. Cutting tree roots requires knowledge of tree biology to avoid killing the tree, and rebuilding a proper base requires plate compaction equipment. However, homeowners can temporarily re-level a few heaved pavers by lifting them, adding sand beneath, and relaying - though this is only a temporary fix if roots remain.

Get multiple quotes because repair approaches vary significantly between contractors. Some focus on minimal disruption (cutting roots and releveling), while others recommend complete base reconstruction for long-term stability. The right approach depends on the tree species, root size, your long-term plans for the tree, and your budget for ongoing maintenance.
