What should be on my fall preparation checklist for my Ottawa garage before winter hits?

Getting your garage ready for Ottawa's winter before the first hard freeze — which typically arrives in late October or early November — prevents small problems from becoming expensive repairs over the course of a long, brutal winter. Ottawa's combination of heavy snowfall, extreme cold snaps, freeze-thaw cycles, and occasional ice storms puts unique stress on garage structures, and an hour or two of fall preparation makes a real difference.

Start with the garage door, which is your largest opening and biggest source of heat loss and weather infiltration. Inspect the bottom seal — if it is cracked, torn, or compressed flat, replace it before winter. A new bottom seal costs $30 to $80 and takes about 20 minutes to install. Check the weatherstripping on the sides and top of the door frame for gaps. Even small gaps let in wind-driven snow and create ice buildup inside the garage. Apply a silicone-based lubricant to all moving parts: hinges, rollers, springs, and tracks. Cold weather thickens standard lubricants and causes metal parts to bind, which puts stress on your garage door opener. WD-40 is not the right product here — use a dedicated garage door lubricant rated for sub-zero temperatures.

Test your garage door opener's manual release mechanism. Pull the emergency release cord and operate the door by hand to make sure it moves freely. During a winter power outage — which can last days during ice storms — your manual release is the only way to get your car out. If the door is difficult to lift manually, your springs may need adjustment or replacement, which is a job for a professional (garage door springs are under extreme tension and dangerous to work on without proper tools and training).

Inspect the roof and gutters from the outside. Clear all debris from gutters and downspouts so meltwater can drain freely — clogged gutters cause ice dams that can damage fascia, soffit, and roofing. Check the roof surface for missing or damaged shingles and repair them before snow covers everything up. Look at the flashing around any vents, chimneys, or where the garage meets the house (for attached garages). Failed flashing is a common source of winter leaks that homeowners do not notice until water damage is already done.

Inside the garage, check the concrete floor for cracks. Water that seeps into cracks and freezes will expand them significantly over the winter through Ottawa's repeated freeze-thaw cycles. Fill any cracks wider than a pencil line with a concrete crack filler ($15 to $30 per tube) before the first freeze. If your floor has significant cracking or heaving, that is a sign of a deeper foundation issue that should be assessed by a professional before it worsens over another winter.

Address drainage and grading around the garage exterior. The ground should slope away from the foundation on all sides at a minimum grade of 5% for the first 1.5 metres. Ottawa's spring thaw sends enormous amounts of water across properties, and poor grading directs that water straight into your garage foundation. Extend downspouts at least 1.5 metres from the foundation using extensions or splash blocks.

Finally, organize your winter supplies inside the garage: ice melt (calcium chloride, not rock salt which damages concrete), snow shovels, a roof rake for clearing heavy snow buildup, a flashlight with fresh batteries, and a small emergency kit in case a winter storm catches you off guard. If you park vehicles inside, keep a bag of kitty litter or sand for traction if ice builds up on the garage floor from melting snow dripping off your car.
