Winter brings cold weather, moisture, and shorter days—so it’s the perfect time to prepare your entire home for comfort, safety, and energy efficiency. This ultimate winter home checklist covers everything from heating systems to insulation…and includes a special section on roof windows, since they play a huge role in keeping your home warm, bright, and well-ventilated during the darker months.

Heating & Energy Efficiency

Service Your Boiler or Heating System

Schedule a professional check-up before temperatures drop. A well-maintained boiler uses less energy and is less likely to break down mid-winter.

Bleed Radiators

Radiators with trapped air heat unevenly. Bleeding releases air pockets so they work more efficiently.

Change or Clean HVAC Filters

Dirty filters force your system to work harder and can spread dust around the home.

Check Your Thermostat

If you don’t have a smart thermostat yet, winter is the perfect time to install one for better energy control.

Windows, Doors & Roof Windows

Inspect All Windows and Doors for Drafts

Run your hand along the frame on a cold day. If you feel air movement, consider weatherstripping or caulking.

Install Thermal Curtains or Blinds

They add an extra layer of insulation and help retain heat at night.

Special Section: Roof Windows (Skylights) – Essential Winter Care

Roof windows face the harshest winter conditions—snow, ice, humidity, and rapid temperature changes. A bit of seasonal maintenance protects both your window and your roof.

Check the Exterior Frame & Flashing

Look for cracks, loose flashing, or worn seals. These are common causes of winter leaks.

Clean the Glass Inside & Out

Clear glass maximizes precious winter daylight. Use non-abrasive cleaners and avoid washing exterior glass in freezing temperatures.

Inspect Seals & Gaskets

Cold weather exposes weak seals quickly. Replace anything cracked, brittle, or loose.

Clear Leaves, Moss & Debris Around the Window

Debris traps moisture and can cause leaks or ice buildup.

Manage Condensation

Use short bursts of ventilation to reduce moisture, especially in kitchens, loft bedrooms, or bathrooms.
Condensation on roof windows is common in winter—keep vents functional and consider thermal blinds if temperatures drop significantly.

Snow Precautions

If snow accumulates heavily, gently clear it with a soft brush (never hot water or metal tools).
Ensure the window can still open for ventilation and that ice isn’t blocking drainage paths.

Roof, Gutters & Exterior Home Care

Clear Gutters of Leaves & Debris

Clogged gutters lead to overflowing water and ice dams.

Check Roof for Loose or Damaged Tiles

Fix before winter storms cause leaks.

Inspect Downpipes

Ensure water can drain freely to prevent freezing or cracking.

Trim Overhanging Branches

Snow-loaded branches can break and damage your roof, windows, or gutters.

---

Insulation & Draft-Proofing

Check Loft & Wall Insulation

Proper insulation keeps heat inside and reduces energy bills.

Seal Gaps Around Pipes & Electrical Outlets

Small gaps allow heat to escape and cold air to enter.

Insulate Water Pipes

Helps prevent freezing (and potential bursting), especially in unheated spaces.

---

Fire & Safety Essentials

Test Smoke & Carbon Monoxide Detectors

Change batteries and check expiry dates.

Service Fireplaces & Chimneys

Creosote buildup can cause fires; a yearly sweep is essential.

Stock Up on Winter Supplies

Rock salt, shovels, torches, blankets, and backup batteries.

---

Indoor Air Quality & Comfort

Clean Humidifiers and Dehumidifiers

Winter air can swing between too dry and too humid—keep units clean for healthier air.

Deep-Clean Vents and Fans

Especially in kitchens and bathrooms where moisture builds.

Rotate Ceiling Fans

Set them to push warm air down into the room.
