Two centimetres versus five. That distinction alone decides whether a plow shows up before your 7 a.m. opening or well after the parking lot has already turned into a hazard. Most property managers sign a snow removal contract without ever pinning that number down, then wonder in January why the lot still has an inch of pack-down at 8 a.m.
A snow contract is really a risk transfer document dressed up as a service agreement. Read it that way and the right questions get a lot more obvious.
The Seven Questions
1. What Depth Triggers Service?
Some contracts trigger at 2.5 cm, some at 5 cm, a few vague ones just say “as needed.” That last phrase should be a red flag. Ask for the exact centimetre threshold in writing, and ask whether it is measured on the lot or pulled from a weather station across the city. Calgary can get a localized dump that a downtown reading never picks up, and a chinook can wipe out three centimetres before the plow arrives, so the measurement method matters as much as the number itself.
Property managers researching how trigger depth gets written into a snow removal contract should ask the contractor to walk through last year’s borderline calls, the storms that landed right at 2.4 or 2.6 cm. Those edge cases show whether the number in the contract actually holds up in practice or just sounds precise on paper.
2. What Is the Response Window?
A 4-hour response after a trigger event sounds fine until you realize that clock might not start until the storm ends, not when it begins. Push for language on both the start trigger and the completion window. Overnight storms need a different promise than a 2 p.m. squall during business hours.
Ask specifically about weekends and stat holidays too. A contractor that promises a 4-hour weekday response but goes quiet on a Sunday morning storm has left a gap that only shows up the first time it matters.
3. Per-Push or Seasonal?
Per-push billing charges for every visit, so costs swing with the winter. A seasonal flat rate smooths that out but only pencils out if the contractor has capacity to actually show up during a back-to-back storm week. Property managers weighing a seasonal snow removal plan against per-push pricing should ask for last winter’s visit count on a comparable property, not just a rate card.
4. Who Carries the Liability?
This is the one clause that gets skimmed and shouldn’t be. If someone slips on ice that formed between the last plow visit and the next one, whose insurance responds? Ask for the certificate of insurance directly, not a verbal assurance that “we’re covered.” Confirm the policy names your property, not just the contractor’s general operations.
Coverage limits vary more than people expect. A landscaping outfit that added snow work as a side offering may carry a fraction of the liability coverage a dedicated winter maintenance contractor holds. Ask for the dollar figure, not just confirmation that a policy exists.
5. Is There Proof of Service?
Timestamped photos or GPS logs turn a dispute into a five-minute email instead of a month of back-and-forth. Contracts without any documentation clause put the property manager in the position of taking the contractor’s word for it after a claim gets filed. That is not a position anyone wants to be in during a slip-and-fall investigation.
6. What Equipment and Crew Size Backs the Promise?
A four-hour response window means nothing if the contractor has one truck covering forty properties. Ask how many sites one crew is assigned during an active storm, and ask what happens when two clients get hit at the same time. The answer separates a contractor sized for the book of business from one that oversold capacity to win the bid.
Ask about backup equipment too. Trucks break down mid-storm, and a contractor without a second unit on standby can slip well past the promised window on the exact day it matters most.
7. What Happens for De-Icing and Follow-Up Passes?
Plowing clears the bulk, but the thin refreeze layer underneath is what actually causes falls. Confirm whether sanding and de-icing sit inside the base snow removal service or get billed separately, and whether a follow-up pass is scheduled automatically after temperatures swing back below freezing. A contract silent on this usually means it is an upsell nobody mentioned until the invoice arrived.
Entrance walkways and wheelchair ramps deserve their own line item too. Lot plowing and walkway de-icing sometimes fall under two different crews with two different trigger points, and property managers rarely find that out until a tenant complains.
Reading the Contract Like a Risk Document
Put those seven answers side by side against last year’s invoice, if you have one. Gaps tend to show up fast. A property manager comparing bids should treat the lowest number with some suspicion, because trigger depth, response window, and crew capacity are usually where the corners get cut to hit that price.
Ask for references from properties similar in size and traffic pattern to yours, not just a client list. A contractor doing well on a quiet residential complex may not be sized for a retail lot with a 6 a.m. opening.
Why the Fine Print Matters More in a Bad Winter
A mild winter hides a weak contract. Nobody notices a slow response time when it barely snows. The contract gets tested in the back-to-back storm weeks, the ones with three trigger events in five days. That is when trigger depth language, crew capacity, and documentation either hold up or fall apart, and by then the lease is already signed for the season.
Worth double-checking before the ink dries, not after the first claim.
