With fall almost coming to an end, Markham and GTA homeowners are in the final stretch before winter officially arrives. The last leaves are dropping, mornings are getting colder, and those early sunsets are a clear reminder that now’s the perfect time to get your home winter-ready. Temperatures in the GTA can swing from mild to minus 20° overnight, so tackling these tasks before the deep freeze hits can help you avoid costly repairs, save on heating, and keep your home running efficiently.

This checklist is brought to you by Michael John Lau and Neeraj Moolchandani, the best REALTORS® in Markham and the GTA, helping homeowners stay prepared and protected all winter long.

1. Clean Your Gutters & Downspouts

Clogged gutters are one of the most common causes of winter home damage in Markham. When leaves and debris block water flow, ice dams can form on your roof, leading to leaks and even structural damage.

Tips for Markham/GTA homes:

• Clean gutters at least once in late fall; twice is ideal for homes surrounded by mature trees

• Inspect downspouts to ensure water flows away from your foundation

• Consider adding gutter guards to reduce maintenance next year

Extra tip: After heavy leaf fall, check your gutters again before the first major snowfall. It’s easier to clean while the leaves are fresh rather than frozen.

2. Schedule a Furnace Tune-Up

Your furnace is the heart of home heating during GTA winters. A well-maintained furnace not only keeps your home warm but also reduces energy bills and prevents dangerous carbon monoxide leaks.

Checklist:

• Replace filters every 2–3 months during the heating season

• Check for unusual noises or odors that could indicate a malfunction

• Ensure vents and registers are clean and unobstructed

• Hire an HVAC professional for a safety and efficiency inspection

Energy tip: A properly serviced furnace can reduce winter heating costs by up to 15%.

3. Seal Drafts Around Windows & Doors

Drafty windows and doors are a major cause of heat loss in Markham homes. Sealing gaps keeps your home warmer, reduces energy bills, and increases overall comfort.

DIY fixes:

• Install weatherstripping around doors

• Apply caulking to window frames

• Use insulated or thermal curtains to trap heat

• Check sliding doors, basement windows, and garage doors for drafts

Pro tip: Small gaps around windows can allow cold air in, even if the windows are new. Inspect carefully.

4. Protect Your Pipes From Freezing

Frozen pipes are common in the GTA during sudden cold snaps and can lead to expensive water damage.

Preventive measures:

• Insulate exposed pipes in garages, basements, and crawlspaces

• Leave cabinet doors open to allow warm air to circulate around sinks

• Maintain indoor temperatures above 18°C, even when away from home

• Shut off exterior water lines and drain hoses before the first freeze

Extra tip: For long vacations, consider a smart thermostat that alerts you if temperatures drop dangerously low.

5. Winterize Your Outdoor Spaces

Snow and ice can damage gardens, patios, and walkways. Winterizing outdoor areas protects your home and makes spring cleanup easier.

Checklist:

• Store or cover patio furniture

• Drain garden hoses and irrigation systems

• Trim overhanging branches that could break under snow load

• Clear and inspect walkways, steps, and driveways for cracks

• Test exterior lights to ensure visibility during long winter nights

Extra tip for families: Keep walkways safe with non-slip mats or ice melt,  especially near play areas and front entrances.

6. Inspect Your Roof

Your roof takes the brunt of GTA winters. Heavy snow, ice, and wind can cause leaks and structural damage if not addressed before winter.

Inspection tips:

• Look for missing, loose, or damaged shingles

• Check for signs of water stains or mold in the attic

• Ensure proper insulation and ventilation to prevent ice dams

• Hire a professional roofer if unsure about the roof condition

Local insight: Older neighborhoods like Milliken Mills, Raymerville, and Thornhill may have aging roofs that require extra attention before winter storms.

7. Test Smoke & Carbon Monoxide Detectors

Winter increases the risk of fires and carbon monoxide exposure due to higher use of furnaces, fireplaces, and space heaters.

Checklist:

• Replace batteries and test alarms on every level of your home

• Install CO detectors near bedrooms and common areas

• Consider interconnected alarms so that if one goes off, all alarms sound

Safety tip: Make sure everyone in the household knows how to respond to alarms during nighttime emergencies.

8. Stock Up on Winter Essentials

GTA winter storms can arrive suddenly. Being prepared ensures safety and convenience during power outages or heavy snow.

Must-haves:

• Ice melt or rock salt for walkways and driveways

• Snow shovels or a snow blower

• Flashlights, batteries, and emergency blankets

• Optional: portable generator for long outages

Extra tip: Keep essential groceries, water, and medications on hand, especially if your home is in a quieter neighborhood or near rural areas in the GTA.
