Ottawa winters are brutal on homes. Five months of freeze-thaw cycles, heavy snow loads, ice dams, de-icer exposure, and extreme temperature swings take a toll on every component of your home's exterior and systems.

Ottawa winters are brutal on homes. Five months of freeze-thaw cycles, heavy snow loads, ice dams, de-icer exposure, and extreme temperature swings take a toll on every component of your home's exterior and systems. Spring is the critical time to identify and address winter damage before it becomes expensive summer emergencies. A thorough spring maintenance routine takes one weekend for the DIY portions and should be supplemented by professional inspections for major systems. The investment of $500–$2,000 in spring maintenance typically prevents $5,000–$20,000 in repair costs over the following year. Here's the complete spring maintenance checklist for Ottawa homes, organized by priority.
Roof inspection: Look from the ground with binoculars for missing or damaged shingles, lifted flashing, and sagging areas. Ottawa's ice dams and heavy snow loads are the leading cause of premature roof failure. If you see damage, schedule a professional roof inspection ($200–$400). Gutter cleaning and inspection: Remove winter debris (leaves, shingle grit, ice dam residue). Check for sagging, loose fasteners, and damage from ice. Flush gutters with a hose to verify proper flow. Inspect downspouts — ensure they discharge at least 6 feet from the foundation. Budget: DIY or $150–$350 for professional cleaning. Foundation inspection: Walk the perimeter looking for new cracks, shifting, or damaged parging. Check that grading slopes away from the house (minimum 1 inch per foot for the first 6 feet). Winter frost heaving can change drainage patterns. Fill any settled areas with topsoil to restore drainage. Siding and trim: Look for damaged, loose, or missing siding panels. Check caulking around windows, doors, and trim — Ottawa's temperature extremes dry out caulking in 3–5 years. Re-caulk any cracked or separated joints. Deck and patio inspection: Check for heaved pavers, loose deck boards, and wobbly railings. Decks may need re-staining (every 2–3 years). Clean the deck with a deck wash before staining — pressure washing too aggressively damages wood fibres. Driveway assessment: Fill asphalt cracks before they expand with spring rain. Schedule seal coating if due (every 2–3 years). Check concrete for salt damage (spalling). Interlock pavers may need re-levelling if frost heaving has shifted them. Fence inspection: Check for leaning posts (frost heaving is the usual cause), loose or missing boards, and gate alignment. Repair while the ground is still soft from spring thaw — setting new posts is easier in April than August.
HVAC tune-up: Schedule air conditioning maintenance before the summer rush. Professional AC tune-up costs $100–$200 and includes refrigerant check, coil cleaning, electrical connections, and thermostat calibration. Book in March or April — June is too late and you'll wait weeks. Furnace filter: Replace the furnace filter if it hasn't been changed in the last 3 months. A clean filter improves efficiency and air quality. HRV (Heat Recovery Ventilator): Clean or replace HRV filters, clean the heat exchange core, and flush the condensate drain. Most Ottawa homes built after 2000 have HRVs — they need seasonal maintenance. Water heater: Check the temperature setting (120°F/49°C is recommended), inspect for leaks or corrosion, and test the pressure relief valve. If your water heater is 10+ years old, consider proactive replacement before it fails. Sump pump test: Pour a bucket of water into the sump pit to verify the pump activates and discharges properly. Check the discharge pipe for blockages. Install a battery backup if you don't have one — sump pump failure during a spring storm is one of the most common causes of Ottawa basement flooding. Outdoor faucets: Turn on outdoor hose bibs and check for leaks. Frozen pipes that cracked over winter will leak when water is restored. If you find a leak, shut off the supply immediately and call a plumber. Window and door inspection: Open and close all windows and doors. Check weatherstripping and replace if worn. Clean window tracks and lubricate hardware. Check window wells for accumulated debris and ensure covers are in place. Smoke and CO detectors: Test all detectors and replace batteries (or replace units if they're 10+ years old). Ontario Fire Code requires working smoke detectors on every floor.
Spring cleanup: Rake leaves, remove fallen branches, and clear garden beds. Don't rush lawn raking — wait until the grass starts growing to avoid damaging dormant turf. Tree and shrub assessment: Look for broken branches from ice and snow damage. Prune damaged branches cleanly to prevent disease. Check for trees leaning toward the house or power lines — schedule removal or trimming with a certified arborist. Grading and drainage: Walk the property after a rain to identify standing water or areas that drain toward the house. Add topsoil or regrading as needed. This is the single most effective action for preventing basement water problems. Outdoor lighting: Replace bulbs, clean fixtures, and test motion sensors. Check landscape lighting for winter damage. Irrigation system startup: If you have an irrigation system, schedule professional startup ($100–$200). This involves gradually pressurizing the system, checking for leaks and broken heads, and programming the controller for the season. Garden planning: Ottawa's last frost date is typically around May 15. Start planning garden beds and container plantings. Order supplies and materials early for spring installation. Window well maintenance: Clear debris from window wells, check drains, and ensure covers are secure. Window well flooding is a common source of basement water entry in Ottawa.
Begin exterior inspections in late March or early April when snow has melted. Schedule professional services (HVAC, gutter cleaning) in April. Complete all maintenance by mid-May before summer heat and storms arrive.
DIY maintenance (inspection, cleaning, minor repairs) costs $200–$500 in materials. Adding professional services (HVAC tune-up, gutter cleaning, roof inspection) brings the total to $500–$1,500. This prevents $5,000–$20,000+ in repair costs.
Testing your sump pump and checking drainage/grading around the foundation. Spring snowmelt and rain are the leading cause of basement flooding in Ottawa. A working sump pump and proper grading are your first line of defence.
Gentle pressure washing (1,500–2,000 PSI with a wide fan tip) can clean siding, decks, and patios. Avoid high pressure on wood siding, stucco, and older brick — it can cause damage. Soft washing (low pressure with cleaning solution) is safer for most Ottawa homes.
