Ottawa's extreme climate demands year-round home maintenance that differs significantly from milder regions. From protecting against ice dams in January to preparing your furnace for the first frost in October, each month brings specific maintenance tasks that prevent costly repairs and extend the life of your home's systems. This month-by-month 2026 calendar organizes every essential maintenance task by the optimal time to complete it, with estimated costs, DIY versus professional recommendations, and links to our detailed guides for each topic. Following this calendar prevents the two most e...
Ottawa's harshest months require vigilant monitoring and proactive maintenance.
Monitor for ice dams on roof edges — if icicles form along the eaves, you may have ice dam conditions. Do not attempt to remove ice dams yourself; hire a professional ice dam removal service ($300 to $600 per visit). Check attic for frost buildup (indicates insufficient ventilation or air sealing). ...
Have your furnace serviced if not done in fall — February is the slowest month for HVAC contractors, so scheduling is easier and prices may be lower ($100 to $200). Check exposed water pipes in unheated areas (garage, crawl spaces) for signs of freezing. Know how to shut off your main water valve in...
As temperatures begin to fluctuate, watch for water infiltration in the basement during snow melt. Ensure downspout extensions are in place to direct snowmelt away from the foundation (minimum 6 feet from the house). Inspect your siding and exterior trim for damage from winter weather. Plan spring p...
Spring is the most important maintenance season in Ottawa — winter damage must be addressed before summer.
Once snow melts, do a thorough exterior inspection. Walk the perimeter and look for: foundation cracks (new cracks or existing cracks that have widened), damaged or displaced downspout extensions, heaved or cracked walkways and driveway sections, damaged siding, trim, or soffit. Clean eavestroughs a...
Book your annual air conditioning tune-up ($100 to $200). Service your deck (power wash, re-stain or seal if needed: $200 to $600 DIY, $500 to $1,500 professional). Check and service outdoor faucets — turn on water supply to outdoor spigots and check for leaks from freeze damage. Inspect window and ...
Summer is project season and the time for outdoor maintenance and major renovations.
Monitor indoor humidity levels — Ottawa summers are humid and indoor humidity above 60% promotes mould growth. Use your AC or a dehumidifier to maintain 40% to 55%. Inspect and clean range hood exhaust fan and bathroom exhaust fans. Check attic ventilation — proper attic ventilation prevents heat bu...
Book your annual furnace service before the fall rush ($100 to $200 — prices increase in October). Clean eavestroughs again after leaf fall begins. Drain and winterize your sprinkler system if you have one ($75 to $150 professional). Disconnect and drain outdoor garden hoses. Shut off outdoor water ...
Preparing for winter is critical to preventing expensive cold-weather emergencies.
Complete final eavestrough cleaning after all leaves have fallen. Verify furnace is operating correctly before sustained cold weather. Replace furnace filter. Inspect and clean fireplace and chimney if used ($150 to $300 professional sweep). Install storm windows if applicable. Check and add attic i...
Monitor for ice dams after the first major snowfall. Keep snow cleared from foundation walls to prevent spring water infiltration. Check that bathroom and kitchen exhaust fans vent to the exterior (not into the attic — a common issue in Ottawa homes that causes attic frost). Monitor furnace operatio...
Eavestrough cleaning (twice per year) and furnace maintenance (annually) are the two most critical tasks. Clogged eavestroughs cause foundation water damage and ice dams. A neglected furnace wastes energy, poses safety risks, and fails when you need it most.
Budget $2,000 to $4,000 per year for routine maintenance on a typical Ottawa home. This covers furnace service, AC tune-up, eavestrough cleaning, filter replacements, sealant refresh, and minor repairs. Deferring maintenance costs far more in emergency repairs.
September or early October is ideal — before the heating season rush. HVAC contractors are less busy and prices are typically lower. Annual furnace service costs $100 to $200 and extends equipment life by 5 to 10 years.
Twice per year: once in late spring (April/May) after winter debris clears, and once in late fall (November) after all leaves have fallen. Homes near mature trees may need a third cleaning in September.
March (for spring/summer projects) and September (for fall/winter projects) are the best times. Booking during off-peak months gives you better pricing, wider contractor availability, and more scheduling flexibility.
