Repair, replace, or just clean? – quick diagnostic

Pavers intact + base shifted → repair

Lift and relay. Keep your existing pavers. From $6/sq ft, most jobs $1,500-$3,000. See sections above.

Joints failed but pavers good → cleaning

Polymeric sand washed out. You don't need a full repair. Cleaning and re-sanding fixes it, from $1.40/sq ft.

Pavers cracked + base intact → replacement

Source matching pavers, swap them in. Quoted per paver. Often part of a section relevel.

Pavers cracked + base destroyed → full rebuild

Repair won't hold. Better to tear out and install fresh. A new interlock driveway runs $21-$25/sq ft plus HST.

Only the joints failed? See interlock cleaning. Base destroyed? We also build new interlock as a full Ottawa interlocking contractor, see interlock driveway installation. For repair numbers by scope, see our interlock repair prices or try the interlock cost calculator.

Our Ottawa interlocking repair crews handle the full range of paver issues: sunken sections, lippage, weeds and ants in the joints, failed polymeric sand, broken or stained pavers, missing edge restraints, and settling near downspouts. We lift the affected pavers, correct the base, reset, and finish with fresh polymeric sand.

  • Sunken driveway, patio, or walkway sections
  • Lippage and uneven paver edges
  • Weeds, moss, and ants in the joints
  • Failed or washed-out polymeric sand
  • Broken, cracked, or stained pavers
  • Loose or missing edge restraints

Why Ottawa homeowners choose us

We fix the cause, not the symptom

Sunken pavers and loose steps are almost always a base or drainage problem. We rebuild the bedding so the fix lasts.

Crew based in Nepean, 20-minute radius to every job

Local crew that knows Ottawa frost cycles. Quick callbacks if anything ever needs attention.

Match your existing pavers

We carry reserve stock from older Techo-Bloc, Permacon, and Unilock lines. Repairs blend in instead of looking patched.

Most repairs done in 1-3 days

Spot repairs same-day. Section relevels 2-3 days. Full driveway/patio relevels 3-5 days.

$2M liability + WSIB cleared

Discontinued Paver Matching

We keep a reserve stock of older Techo-Bloc and Permacon lines

If your driveway was installed 10+ years ago, the original paver line may be discontinued. We carry reserve stock and source close matches so your repair blends in.

Areas we serve

Kanata. Lift-and-relay and full repair across Kanata Lakes, Bridlewood, Morgan’s Grant, Beaverbrook, and Katimavik. Frost-heave on undersized builder bases is the most common Kanata failure we fix – $1,500-$3,000 typical relevel.

Barrhaven. Repair work across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Most Barrhaven repairs are sunken sections near downspouts – we fix the drainage as part of the repair.

Orleans. Sunken paver relevel across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Older Orleans driveways often have failed polymeric sand – we vacuum out and replace.

Nepean. Repair work across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean trees mean root-lifted pavers – we cut the root, regrade, and relay.

Stittsville. Section relevels across Jackson Trails, Crossing Bridge Estates, and Amberwood. Larger Stittsville driveways often need multi-section relevels – $3,000-$6,000 typical.

Gloucester. Repair work across Beacon Hill, Blackburn Hamlet, and Hunt Club. Gloucester driveways exposed to heavy road salt need re-sanded joints every 3-5 years to keep weeds and ants out.

Manotick. Estate driveway repair across Mahogany, Manotick Estates, Long Island, and Manotick Village. Long Manotick drives often have isolated settled sections – we spot-repair instead of full rebuilds.

Riverside South. Repair work across Honey Gables and the Riverside South village. Newer Riverside South pavers usually only need a relevel and re-sand, not full rebuild.

Centretown. Tight-access repair across the Golden Triangle and Centretown West. Heritage walks, rear-laneway pavers, condo courtyards – we bring small equipment.

Westboro. Heritage repair across Westboro Beach, Highland Park, and McKellar Park. Period-correct paver matching is part of the work – we source the closest discontinued line or recommend a contrasting border solution.

Alta Vista. Repair and relevel across Heron Park, Faircrest Heights, and Playfair Park. Root pressure and mature tree canopies cause a lot of Alta Vista uplift – we address the root cause.

The Glebe. Heritage repair across the Glebe and the Old Ottawa South border. Narrow lots, neighbour-shared walks, original heritage pavers – colour matching and access coordination are part of the work.

Interlock repair FAQs

How much does interlock repair cost in Ottawa?

Most interlock repairs in Ottawa fall between $1,500 and $3,000 depending on the size of the affected area, base condition, and whether replacement pavers are needed. Lift and relay starts from $6 per sq ft and small spot repairs from $400, plus HST.

Can my settled driveway be repaired or does it need replacement?

Most settled driveways can be repaired by lifting the affected pavers, correcting the base, and resetting. Full replacement is only needed when base failure is widespread or when pavers are too damaged to reuse.

Why is my interlock sinking?

Common causes are inadequate base depth, poor compaction during installation, washouts from downspouts, broken weeping tile, or improperly compacted utility trenches under the pavers.

How do you get rid of weeds in the joints?

We pressure-wash or vacuum out old joint sand, replace any failed pavers, and refill the joints with polymeric sand that hardens to resist weed growth and ant tunnels.

How long does an interlock repair take?

Most spot repairs are completed in 1 working day. Section relevels take 1 to 3 days, and full driveway or patio relevels take 3 to 5 days depending on size.

Can you match my existing pavers?

Usually, yes. We keep reserve stock from older Techo-Bloc, Permacon and Unilock lines and source close matches for the rest. If a line is gone and nothing blends in, we suggest a contrasting border or inlay instead.

What is the best polymeric sand?

For Ottawa we recommend premium polymeric sands from Techniseal, Alliance Gator, or similar. These hold up to freeze-thaw cycles and Ottawa snow-clearing.

Can you fix interlock around a sunken downspout?

Yes. Sunken pavers under downspouts are common in Ottawa. We address the underlying drainage issue – usually by extending the downspout discharge – before resetting the pavers.

Do you offer interlock repair near me in Ottawa?

Yes. We repair interlock across Ottawa, including Kanata, Barrhaven, Orleans, Nepean, Stittsville, Gloucester, Manotick, Riverside South, Centretown, Westboro, Alta Vista, and The Glebe.
