Concrete Work in Montreal: Driveways, Sidewalks & Repair Cost Guide

If you own a home in Montreal, chances are you’ve noticed it: a cracked driveway after another brutal winter, a sidewalk slab that’s heaved out of place, or crumbling parging along your foundation. Concrete takes a beating in this city. Between freeze-thaw cycles, road salt, and decades-old installations that were never built to today’s standards, small cracks turn into real structural problems faster than most homeowners expect.

At Tross Construction, concrete work is one of the most common calls we get across Montreal not glamorous renovation work, but the kind that protects your property, your curb appeal, and, in some cases, your foundation itself. This guide walks through what concrete work typically involves, what it costs in 2026, and how to tell the difference between a cosmetic fix and a job that needs to happen now.

Why Montreal Concrete Takes So Much Damage

Montreal’s climate is uniquely hard on concrete. Water seeps into tiny surface cracks, freezes, expands, and widens the crack. Repeat that cycle every winter for a decade, and a hairline crack becomes a slab that’s heaving, sinking, or crumbling. Add road salt (which accelerates surface scaling) and the clay-heavy soil common across much of the city, which shifts seasonally and puts pressure on slabs from below, and it’s no surprise concrete here needs more frequent attention than in milder climates.

This is also why “patch it and hope” rarely works long-term in Montreal. A proper repair needs to account for drainage, soil movement, and the freeze-thaw cycle, not just fill the visible crack.

Common Concrete Work We Handle in Montreal

Driveway repair and replacement. Cracked, sunken, or heaved driveway sections, whether it’s a patch job on a small section or a full tear-out and repair.

Sidewalk repair. City sidewalks bordering your property are often your responsibility to maintain in good condition, and uneven slabs can be a tripping hazard and a liability issue.

Parging repair. Parging is the thin concrete coating applied to foundation walls above grade; it protects the foundation from moisture and physical damage, and in Montreal it cracks and flakes off far more often than most homeowners realize until it’s pointed out.

Small concrete jobs. Steps, patios, curbs, and small pads for AC units or sheds are jobs too small for some contractors to bother with, but exactly the kind of work that prevents bigger problems later.

Concrete crack injection and resurfacing. For cracks that aren’t structural but are letting water through, injection and resurfacing extend the life of existing concrete without a full replacement.

Concrete Work Cost in Montreal: 2026 Pricing Guide

Pricing depends heavily on the scope, access to the site, and whether old concrete needs to be removed first. Here’s a realistic breakdown based on projects Tross Construction handles across Montreal:

Service	Typical Cost Range (CAD)
Driveway crack repair / patching	$300 – $900
Full driveway replacement (per sq ft)	$8 – $15 / sq ft
Sidewalk slab repair (per section)	$400 – $1,200
Parging repair (per linear foot)	$25 – $50 / linear ft
Small concrete jobs (steps, pads, curbs)	$500 – $2,500
Concrete crack injection	$400 – $900 per crack
Concrete resurfacing (per sq ft)	$5 – $9 / sq ft

A few things that move pricing up: how much old concrete needs to be broken out and hauled away, site access (tight urban lots and rear-yard work cost more due to labor), rebar or mesh reinforcement requirements, and whether drainage correction is needed alongside the repair. Older Montreal properties, especially in boroughs with narrow lots and laneway access, often see slightly higher labor costs simply due to equipment access.

We provide a free on-site assessment before quoting, because two driveways that look similarly cracked can have completely different root causes and completely different price tags to fix properly.

Repair vs. Full Replacement: How to Decide

This is the question we get asked most. Here’s how we generally guide Montreal homeowners:

Repair makes sense when cracks are isolated and not spreading, the slab hasn’t visibly heaved or sunken, and the damage is cosmetic or early-stage. Crack injection and patching can add years of life at a fraction of replacement cost.

Replacement makes sense when multiple sections are cracked or heaving, there’s visible pooling water indicating drainage failure under the slab, the concrete is more than 20–25 years old, or repeated patch jobs haven’t held up. In these cases, a full tear-out addresses the underlying cause (usually soil movement or poor base prep) instead of just the symptom.

A good contractor should walk you through both options honestly, not default to the more expensive one.

The Concrete Work Process: What to Expect

1. On-site assessment. We inspect the affected area, check for underlying drainage or soil issues, and determine whether repair or replacement is the right call.

2. Quote and timeline. You receive an itemized quote, not a vague estimate, along with a realistic project timeline.

3. Demolition (if needed). For replacement work, old concrete is broken out and hauled away, and the base is inspected and corrected if soil compaction or drainage is contributing to the damage.

4. Base preparation. A properly compacted gravel base is critical in Montreal’s climate; skipping this step is the number one reason concrete fails prematurely here.

5. Forming and reinforcement. Forms are set to the correct grade and slope (important for drainage away from your home), and rebar or wire mesh is installed for structural strength.

6. Pouring and finishing. Concrete is poured, leveled, and finished to the appropriate texture broom finish for driveways and walkways to prevent slipping and smoother finishes for patios.

7. Curing and sealing. Proper curing time is essential before the surface can handle weight or traffic, and a quality sealer helps protect against Montreal’s salt and freeze-thaw damage going forward.

Smaller patch and repair jobs are often completed in a single day. Full driveway or sidewalk replacements typically take 3–7 days, including curing time, before the surface is ready for vehicle traffic.

How to Choose a Concrete Contractor in Montreal

A few things worth checking before hiring:

• Do they address the underlying cause (soil, drainage) or just patch the visible crack?
• Do they provide a written, itemized quote?
• Do they account for Montreal’s freeze-thaw cycle in how they prep the base and reinforce the pour?
• Do they offer a workmanship warranty?
• Can they show recent local work, ideally in your borough or a similar climate-exposed area?

Frequently Asked Questions

How long does new concrete need to cure before I can drive on it?

Typically 7 days for foot traffic and around 7–10 days before vehicle traffic, though full strength curing continues for about 28 days. Tross Construction will give you exact timing based on weather conditions at the time of your pour.

Is my cracked sidewalk my responsibility or the city’s?

In most Montreal boroughs, homeowners are responsible for maintaining the sidewalk section bordering their property in safe condition, though rules vary by borough. We can help clarify what applies to your specific address.

Can concrete repair be done in winter?

Pouring new concrete isn’t recommended in freezing temperatures, but crack injection and some repair work can be done seasonally. Spring through fall is the ideal window for most driveway and sidewalk projects in Montreal.

Why does my driveway keep cracking even after repairs?

Repeated cracking usually means the underlying cause poor base compaction, drainage issues, or soil movement—was never addressed, only the surface crack. A proper assessment identifies the root cause before repairing.

How much does it cost to fix a small concrete crack versus replacing the whole driveway?

A small crack repair typically runs $300–$900, while full driveway replacement runs $8–$15 per square foot. If cracking is isolated and the slab hasn’t heaved, repair is usually the more cost-effective choice.
