A driveway extension in Ottawa typically costs $25 to $35 per square foot of new interlock area. Common 100–250 sq ft extensions usually fall between $2,500 and $8,500.

Our Ottawa crews specialize in tidy driveway widening and extension projects. We remove sod, excavate to frost-proof depth, install a compacted base, cut the existing driveway cleanly, install interlock pavers, and finish with polymeric sand. The result looks intentional — not like an afterthought tacked onto your existing driveway.

View projectMost driveway extensions need colour and dimension matches to existing pavers. We carry reserve stock and can usually match installs from the last 10-15 years.
Kanata. Driveway extensions across Kanata Lakes, Bridlewood, Morgan's Grant, Beaverbrook, and Katimavik. Most Kanata extensions add a third parking spot — typical $2,500-$5,500 single-car widening.
Barrhaven. Extension work across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Tight Barrhaven lots usually limit extensions to one extra spot — we check setback rules before quoting.
Orleans. Driveway widening across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Older Orleans builds often have asphalt drives that we saw-cut cleanly and tie into the new interlock extension.
Nepean. Extension installs across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean lots support both-side widening — $5,000-$8,500 typical.
Stittsville. Larger extensions across Jackson Trails, Crossing Bridge Estates, and Amberwood. Stittsville lots often support RV parking pads and turnaround extensions — $6,000-$12,000 range.
Gloucester. Extension work across Beacon Hill, Blackburn Hamlet, and Hunt Club. We confirm City of Ottawa curb-cut and zoning rules before extending toward the property line.
Manotick. Estate driveway extensions across Mahogany, Manotick Estates, Long Island, and Manotick Village. Larger Manotick lots often need extensions for multiple vehicles, trailers, or boat parking.
Riverside South. Extension installs across Honey Gables and the Riverside South village. New-build Riverside South driveways are usually narrow — extensions to fit a second car are a common request.
Centretown. Tight-access extension work across the Golden Triangle and Centretown West. Most Centretown lots can't widen toward the street — we extend rear-laneway or side-yard parking instead.
Westboro. Heritage-friendly extensions across Westboro Beach, Highland Park, and McKellar Park. Period-correct paver matching and clean tie-ins to original stone walls.
Alta Vista. Extension installs across Heron Park, Faircrest Heights, and Playfair Park. Larger Alta Vista lots support both-side widening and turnaround pads — we grade away from the foundation.
The Glebe. Heritage extension work across the Glebe and the Old Ottawa South border. Narrow lots limit street-side extensions — we coordinate with the City on curb-cut rules and neighbour clearance.
Driveway extensions in Ottawa typically cost $25 to $35 per square foot. Most single-car extensions land between $2,500 and $5,000, while wider extensions run $5,000 to $8,500.
Most driveway extensions are completed in 2 to 4 working days, including excavation, base, paver installation, and cleanup.
We try to match the closest available paver. If your existing driveway is asphalt or concrete, we usually recommend a paver that complements your home rather than trying to mimic asphalt.
You generally do not need a permit to widen your driveway on private property, but the City of Ottawa regulates driveway width at the curb and the curb cut. We confirm requirements during the consultation.
Most Ottawa neighbourhoods allow extensions to within a small setback of the property line. We check zoning rules for your specific lot before quoting.
Asphalt and interlock react differently to frost, so some seasonal movement is normal. A proper 10–12 inch compacted base under the extension minimizes settling.
Yes. Our standard driveway extensions are built to handle passenger vehicles, trucks, and most SUVs. We can upgrade the base for RVs, trailers, or commercial vehicles.
Yes. Sod and topsoil removal is included in the extension quote. We haul away the excavated material as part of the project.
It can if not done properly. We grade the new pavers to direct water toward the street or yard, away from your foundation.
Yes. We install interlock driveway extensions across Barrhaven, including Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Most Barrhaven extensions land between $2,500 and $8,500.
Yes. We install interlock driveway extensions across Kanata, including Kanata Lakes, Bridlewood, Morgan's Grant, Beaverbrook, and Katimavik. We match new pavers to your existing driveway when possible.
