Service

So the right crew reviews your project.

No obligation. We reply within one business day.

Ice control options

Walkway and step salting

The residential add-on that stops the 7 am skating rink between door and car.

Parking lot salting

Scheduled and storm-triggered lot salting, including zero-tolerance programs for high-traffic sites.

Freezing rain response

Crews dispatched on ice events, not just snowfalls – the storms that actually put people in emergency rooms.

Pet- and plant-friendlier options

Alternative de-icers available where regular road salt is too hard on paws, concrete, or gardens.

Why ice control is its own service

Freeze-thaw is relentless

Meltwater refreezes nightly from November to April – one salting is never the job.

It is the liability line

Slip-and-fall claims come from ice, not snow. Documented salting is the defence.

Right product, right dose

Salt, treated salt, or alternatives – matched to temperature, surface, and traffic.

Our Process

How a salting program runs

Surface assessment

What freezes, where it drains, and who walks on it.

Program in writing

Trigger conditions, coverage, and price – seasonal or per-application.

Condition monitoring

We watch temperature swings and ice events, not just snowfall totals.

Treated and logged

Every application logged with time and conditions.

De-Icers Used on Ottawa Driveways, Walkways and Parking Lots

Sodium chloride, the working default

Rock salt is bulk sodium chloride, and it works by dissolving into surface moisture and lowering the freezing point of the solution that forms. It is inexpensive, widely available and effective through most of an Ottawa winter, but its practical performance falls away as the pavement temperature drops toward roughly minus twelve.

Calcium chloride for the cold end

Calcium chloride keeps working at temperatures where sodium chloride has effectively stopped, and it pulls moisture out of the air to begin dissolving instead of waiting for melt to start it. It costs more per application, so it goes where it earns that cost: deep-cold events, north-facing entrances and permanently shaded steps.

Brine and pre-wetting

Brine is salt already in solution, applied to a dry surface before the weather arrives. Because it is liquid it stays where it is put instead of bouncing off into the grass, it starts working the moment precipitation lands in it, and it uses noticeably less product than treating the same surface after ice has already bonded to it.

Where salt is the wrong answer

Chloride is hard on concrete that has not had a full year to cure, on interlock and natural stone, on the jointing sand between pavers, and on the strip of lawn and root zone that runoff drains into. On those surfaces the sensible answer is a lower application rate, a different product, or grit for traction instead of chemistry.

One application is never the whole job

Melting ice produces water, and that water runs downhill and refreezes as soon as the temperature drops back, usually at the foot of a slope, along a gutter line or under a downspout discharge. Ice control is a condition managed across the season, which is why applications are timed to the cycle rather than to a complaint.

Freeze-thaw

Why Freeze-Thaw Cycles Drive Ice Control Demand in Ottawa

The hazard in an Ottawa winter is rarely the snowfall itself. It is what the same snow does once it has melted a little. A sunny afternoon on a south-facing driveway sends meltwater across the surface and down the slope, the temperature drops back through zero at dusk, and by evening there is a sheet of clear ice at the foot of the drive, along the gutter line and directly under the downspout, which is exactly where people walk. Nothing new fell that day. The City’s own climate work points the same way: projections show winter freeze events increasing by about a third, with winter temperatures sitting near zero far more of the time. Read as an operating forecast rather than a weather story, that means more freezing rain, more melt and refreeze, more flash freeze at dusk, and more freeze-thaw damage to concrete, asphalt and interlock. Ice control is the part of this trade that grows, not the part that shrinks. Practically, that is why a salting program is written around trigger conditions and temperature rather than snowfall totals, why the product is chosen for the pavement temperature on the night instead of out of habit, and why every application is logged with the time and the conditions observed. A property treated on the cycle stays walkable. A property treated after a complaint has already had the incident.

Snow Removals Ottawa treats ice control as its own discipline – monitored, treated, and logged all season across Ottawa – not an afterthought bolted onto plowing.

Ottawa's real winter hazard is ice

Snow gets the headlines, but the freeze-thaw cycle does the damage. Ottawa swings across the freezing mark dozens of times a winter, and every swing turns meltwater into black ice on walkways, steps, and lot entrances. A salting program treats ice as a condition to be managed all season – monitored, treated, and logged – rather than an emergency to react to after someone falls. It pairs naturally with a residential contract or a commercial route.

Salting and ice control – FAQs

Is salting included with snow clearing?

It is a separate add-on, because not every property wants salt. Most commercial clients bundle it; residential clients usually add walkway and step salting to their seasonal contract.

Does salt work in extreme cold?

Regular rock salt loses effectiveness around -12 C. Below that we switch to treated salt or alternative de-icers that keep working in deep cold – part of why product choice matters.

Do you have pet-safe de-icer options?

We can run alternative de-icers that are gentler on paws, concrete, and plantings on request. They cost more per application, so we use them where they matter – walkways and entrances – and standard product elsewhere.

What is a zero-tolerance salting program?

A program where surfaces are kept ice-free at all times – salting runs proactively on every event and every freeze-thaw cycle, not just after complaints. It is the standard for medical, retail, and high-traffic commercial sites.
