What This Page Covers

  • Lift and relay unstable paver sections
  • Replace failed bedding/base zones and compact properly
  • Restore joints and drainage flow for long-term stability

Service Detail

Weed growth in joints is usually a symptom, not the root problem. When interlock moves, joints open and moisture retention rises, creating ideal weed conditions. Proper repair combines structural reset with joint stabilization and runoff correction.

In Hamilton freeze-thaw cycles, quick patch repairs often fail again within one or two seasons. We use a repair-first scope that prioritizes durability over short-term appearance.

Frequently Asked Questions

Lower Hamilton, Ancaster Heights, Dundas and the Mountain neighbourhoods all sit on heavy Queenston and Halton clay that holds winter moisture. When that saturated clay freezes, it expands roughly 9 percent in volume and lifts the base unevenly, then settles irregularly as it thaws. A base built without geotextile fabric and without 6+ inches of compacted 3/4-clear limestone moves every winter. Proper reconstruction with the right depth and fabric stops the cycle.
Recurring weeds mean the polymeric joint sand has failed. Three Hamilton-specific causes: (1) original install used regular stone dust instead of polymeric sand; (2) polymeric sand was installed over a moving base and fractured; (3) pavers have exceeded the 5 to 10 year polymeric lifespan. Power-washing out the old sand, allowing joints to dry, then installing Techniseal HP Next-Gel or Alliance Gator Maxx G2 polymeric sand typically eliminates weeds for 5 to 8 years.
Spot lift-and-relay of a 10 to 25 sq ft sunken area: $700 to $1,700. Full polymeric re-sanding of an average Hamilton driveway (500 to 700 sq ft): $1,400 to $2,600. Edge restraint replacement with re-sanding: $2,400 to $4,800. Partial reconstruction of a failed 100 to 200 sq ft zone including base correction: $3,800 to $8,500. Full driveway rebuild with new 6 to 8 inch 3/4-clear base: $18 to $28 per square foot.
For Unilock Roman Classic, Holland Stone and Brussels Block installed after 2005, matching is usually possible through Unilock's Hamilton distributor. Pre-2005 discontinued colours and Techo-Bloc lines before the current catalogue are harder to match; we typically borrow pavers from an inconspicuous area (under a deck, along a garage wall) and install the new stock there instead. Honest colour expectations are discussed before the quote is signed.
Unilock and Techo-Bloc offer transferable lifetime manufacturer warranties on the pavers themselves, but those cover material defect (spalling, manufacturing cracks), not installation failure or settlement. Homeowner insurance rarely covers sinking or shifting interlock because it is classified as wear. Seven Stones Landscape backs every repair with a 5-year workmanship warranty on our work; that is separate from the paver manufacturer warranty.
For a free online estimate, we respond within 24 hours with a ballpark range based on photos and measurements. On-site inspections book within 3 to 7 days. Small repairs (lift-and-relay, polymeric re-sanding) often start within 2 weeks of signing. Spring and post-winter repairs fill up by March, so requesting an "interlock repair near me" estimate in February gives the best scheduling options. Seven Stones Landscape is ICPI certified, carries $5M liability and full WSIB, Est. 2013.

Detailed Local Guidance for Interlock Repair in Hamilton: Fix Shifting Pavers and Weed Growth

Homeowners comparing contractors for interlock repair in hamilton: fix shifting pavers and weed growth should look beyond surface appearance and confirm the technical scope behind the quote. In Ontario conditions, durability is driven by excavation depth, compaction discipline, moisture management, and transition detailing around nearby surfaces. When those fundamentals are rushed, short-term visual improvements can still fail after one or two freeze-thaw cycles. Our recommendation is always to align design intent with structural method so the finished project remains stable, safer, and lower-maintenance over time.

We also advise homeowners to compare proposals by lifecycle value. A lower upfront number may exclude drainage detail, edge restraint, or base depth needed for long-term performance. A clear written scope should define what is rebuilt, what is preserved, and how water movement is controlled across the work area. This transparency helps you make decisions with confidence and prevents repeated patch spending in future seasons.

Planning, Pricing, and Long-Term Value

A strong project outcome starts with accurate scoping. We assess access constraints, grade behavior, tie-ins to existing structures, and how water moves during storms. That allows us to provide practical options: focused structural correction, phased upgrades, or full rebuild where needed. This approach protects budget while keeping quality standards high.

For homeowners comparing bids, ask exactly what base depth, compaction method, and drainage details are included. Surface finishes can look similar on day one, but long-term performance depends on what is built below. In Ontario, freeze-thaw and seasonal moisture expose weak preparation quickly, especially around transitions and edges.

If you want related scope in one plan, we can coordinate interlock patios retaining walls grading and drainage concrete work and sod restoration. You can also explore our problem and solution pages for issue-specific guidance before booking a quote.

How to Evaluate Contractors for This Work

Ask how the contractor verifies elevations, compacts structural layers, and handles runoff through finished transitions. Ask for written details, not verbal assumptions. High-quality execution is measurable before construction starts.

Request local project photos with specific scope notes and compare timelines by phase. Reliable teams explain prep, installation, and closeout clearly so there are no surprises during construction.
