\nHow can I prepare my house for winter?<\/h2>\n
The best way to prepare your home for winter<\/strong> is to see it as a set of systems that all need to work together: the structure (roof, walls, foundation), heating, insulation, moisture control and safety. Rather than trying to do everything in one stressful sprint, the ideal is to spread tasks out over fall and early winter, starting with whatever could cause the biggest damage if it\u2019s not done.<\/p>\nInfo box \u2013 The \u201chouse walkthrough\u201d reflex:<\/strong>
\nBefore the first real cold snap, do a full walkthrough of your property, outside and inside, as if you were an inspector. Roof, gutters, foundation, windows, basement, mechanical room, rarely used rooms: write down anything that looks unusual (stain, crack, smell, draft). This first visual scan gives you a clear list of priorities to tackle.<\/div>\n1. Inspect the roof and attic<\/h3>\n
The roof is your shield against snow and freezing rain. A small leak starting at a minor defect can turn into major water damage after a few storms. From the ground (or with a professional if needed), check:<\/p>\n
\n- whether shingles are missing, warped or torn;<\/li>\n
- whether joints around chimneys or vents look cracked;<\/li>\n
- whether you\u2019ve had large icicles or ice dams along the eaves in past winters;<\/li>\n
- whether the attic insulation is dry, even and sufficient.<\/li>\n<\/ul>\n
A poorly insulated or poorly ventilated attic lets heat escape, creates condensation and encourages ice buildup on the roof. Fixing this before winter protects both your comfort and your home\u2019s value.<\/p>\n
2. Have the heating system checked<\/h3>\n
Your heating system will be working hard for several months in a row. Preventive maintenance (cleaning, adjusting, checking components) reduces the risk of breakdowns, improves efficiency and can even extend the equipment\u2019s lifespan. A dirty filter, for example, reduces airflow and quietly increases your power bill.<\/p>\n
To get a detailed overview of what to check on the mechanical side, you can take inspiration from this winter-prep checklist<\/a> from a major home-improvement retailer.<\/p>\n3. Check insulation and caulking<\/h3>\n
Every little gap around a window, outlet or door is an open door for cold air. On a cool day, simply run your hand along window frames and doors: if you feel a draft or cold air, you may need to redo caulking or replace weatherstripping. These small projects are relatively inexpensive but have a huge impact on comfort and energy use.<\/p>\n
4. Protect vulnerable plumbing<\/h3>\n
A few key points you should never overlook:<\/p>\n
\n- shut off exterior water valves and drain outdoor faucets;<\/li>\n
- insulate pipes that run near exterior walls or through cooler areas;<\/li>\n
- avoid letting certain rooms get too cold, especially if plumbing is in the walls.<\/li>\n<\/ul>\n
A frozen pipe that bursts can destroy a basement in minutes. A bit of prevention saves a lot of stress (and money).<\/p>\n
\nWhat is the first thing to clean in the house?<\/h2>\n
We often associate winter with \u201ccocooning\u201d: more cooking, cozy family time, movie nights, inviting friends over. But before enjoying all of that, there\u2019s one clear priority when it comes to cleaning: everything that handles water around the house \u2013 meaning the gutters<\/strong> \u2013 and then everything that handles air inside (filters and vents).<\/p>\n1. Gutters: the first line of defense<\/h3>\n
Clogged gutters are responsible for a large share of water infiltration around roofs and foundations. Leaves, pine needles, small branches, ice\u2026 all of it can block water flow. When water can\u2019t drain properly, it overflows, runs behind siding or pools next to the house. In winter, that water can freeze and put pressure on materials.<\/p>\n
\n- Thoroughly clean the gutters in fall;<\/li>\n
- Make sure downspouts are clear;<\/li>\n
- Add a downspout extension if water is discharged too close to the foundation.<\/li>\n<\/ul>\n
2. Clean filters and ventilation grilles<\/h3>\n
Inside the house, the very first things to clean before winter are the filters that control air circulation:<\/p>\n
\n- furnace or heat-pump filters;<\/li>\n
- heat-recovery ventilator (HRV) filter, if you have one;<\/li>\n
- bathroom fan grilles and vents;<\/li>\n
- kitchen range hood filter.<\/li>\n<\/ul>\n
A clean filter lets air move freely, which helps both heating and humidity control. In winter, because we open windows less, indoor air quality depends heavily on these mechanical systems.<\/p>\n
For a simple reminder of the key maintenance steps, you can check this list of easy winter-prep tips<\/a>, which highlights the main priorities.<\/p>\n3. Inspect \u201cproblem\u201d areas<\/h3>\n
Use this cleaning time to take a look at the spots where moisture often hides:<\/p>\n
\n- basement corners near the foundation;<\/li>\n
- window sills on the ground floor and in the basement;<\/li>\n
- baseboards near the patio door;<\/li>\n
- room corners where furniture blocks airflow.<\/li>\n<\/ul>\n
Even a small stain or musty smell at this stage is a warning sign worth taking seriously.<\/p>\n
\nShould you heat every room in the house in winter?<\/h2>\n
This is a very common question, both for saving energy and managing comfort. The idea of completely shutting off heat in certain rooms may sound sensible, but it carries some risks. The goal isn\u2019t to keep every room at 22\u00a0\u00b0C, but to make sure no area turns into a \u201cfridge\u201d inside your home.<\/p>\n
1. Minimum temperature to respect<\/h3>\n
In rooms that you don\u2019t use much (guest room, office, playroom, storage), you can turn the heat down, but it\u2019s not recommended to let the temperature drop below about 15\u00a0\u00b0C<\/strong>. Below that, walls and surfaces get too cold, which greatly increases the risk of condensation whenever moisture is present in the air.<\/p>\n2. Don\u2019t completely isolate a room from the rest of the house<\/h3>\n
Keeping a door tightly closed for weeks creates stagnant air. Without circulation, humidity builds up, the smell gets heavier and the room can develop mold patches behind furniture. It\u2019s better to:<\/p>\n
\n- leave the door cracked open from time to time;<\/li>\n
- allow slight airflow, either by convection or mechanical ventilation;<\/li>\n
- avoid storing very moisture-sensitive items (paper, fabrics) directly against exterior walls.<\/li>\n<\/ul>\n
3. Special attention to the basement<\/h3>\n
The basement is naturally cooler and closer to moisture sources (soil, foundation, drains). A basement that\u2019s too cold becomes an ideal environment for mold, especially if the walls are not perfectly insulated. Keeping a stable temperature and regularly checking walls, corners and floors are good habits to prevent serious long-term issues.<\/p>\n
Broker\u2019s tip:<\/strong>
\nDuring a winter showing, buyers immediately feel whether a home has even, comfortable heat. A very cold or damp room sends a negative signal, even if technically it\u2019s just a thermostat set too low. Overall impression plays a huge role in the decision to buy.<\/div>\n

<\/h2>\n<\/h2>\nWhat temperature helps prevent mold?<\/h2>\n
Mold is at the heart of winter prep concerns. It doesn\u2019t appear by magic: it needs three conditions to grow \u2013 moisture, a surface to hold onto and a suitable temperature. The goal in a home is to keep it warm enough while controlling humidity.<\/p>\n
1. The comfort zone for your home<\/h3>\n
In general, a temperature around 20\u00a0\u00b0C<\/strong> during the day is an excellent compromise. It\u2019s not just about human comfort: at this temperature, interior surfaces (walls, ceilings, floors) stay warm enough to reduce the risk of excess condensation.<\/p>\n2. Recommended relative humidity<\/h3>\n
The key factor for mold is humidity. Ideally, indoor relative humidity should stay between 35\u00a0% and 45\u00a0%<\/strong>. Below that, the air becomes too dry (uncomfortable for skin, airways and some materials). Above that, condensation is more likely to appear:<\/p>\n\n- on windows, especially older ones;<\/li>\n
- in corners of exterior walls;<\/li>\n
- in the basement;<\/li>\n
- in poorly ventilated bathrooms.<\/li>\n<\/ul>\n
A simple hygrometer placed in a central room quickly shows you what\u2019s going on. If you regularly see values above 50\u00a0%, especially in winter, it\u2019s time to adjust your habits (ventilation, shower length, indoor drying, etc.).<\/p>\n
3. Reducing humidity at the source<\/h3>\n
Here are a few concrete habits to adopt:<\/p>\n
\n- Run the kitchen range hood (vented to the outside) when boiling water or cooking for long periods.<\/li>\n
- Keep the bathroom fan running during and for 10\u201315 minutes after showers.<\/li>\n
- Limit drying large amounts of laundry indoors without proper ventilation.<\/li>\n
- Air out the home briefly but regularly (a few minutes a day) by opening a window slightly.<\/li>\n<\/ul>\n
To make sure you don\u2019t forget anything in your seasonal routine, a checklist like this fall home-maintenance guide<\/a> is very handy.<\/p>\n
\n\ud83c\udf28\ufe0f Preparing the exterior of the home for winter<\/h2>\n
The exterior takes the full force of storms, snow, freezing rain and wind. Proper prep reduces the risk of damage, protects the structure and even makes snow removal easier all winter long.<\/p>\n
1. Roof, gutters and site drainage<\/h3>\n
In addition to roof inspection and gutter cleaning, watch how water behaves around the house during heavy rain or thaw. The goal is for water to always flow away from the foundation. If you see standing water near the house, damp marks on the foundation or sinking soil, these are signs that drainage improvements would help.<\/p>\n
2. Entrances, steps and balconies<\/h3>\n
Check the condition of steps, balconies and railings. In winter, the combination of snow + ice + extra weight increases stress on structures. A step that\u2019s already weak or a loose railing in the fall may become hazardous in January or February.<\/p>\n
3. Outdoor furniture and accessories<\/h3>\n\n- Store cushions, fabrics and accessories that could rot or deteriorate under snow.<\/li>\n
- Cover or bring in the BBQ, and safely close the gas cylinder.<\/li>\n
- Store patio furniture or at least move it away from areas where ice chunks might fall from the roof.<\/li>\n
- Shut off outdoor water valves, drain hoses and store them.<\/li>\n<\/ul>\n
\n\ud83d\udca1 Energy, safety and small actions with big impact<\/h2>\n
Once the big items are handled (roof, heating, gutters, humidity), there are still plenty of fine-tuning steps that further improve comfort and safety while helping you save energy.<\/p>\n
1. Boost energy efficiency<\/h3>\n\n- Install or check weatherstripping around exterior and entry doors.<\/li>\n
- Use curtains or blinds to keep heat in at night.<\/li>\n
- Program thermostats to lower the temperature slightly at night or when you\u2019re away for longer periods.<\/li>\n
- Check outlets on exterior walls and seal them if needed to limit drafts.<\/li>\n<\/ul>\n
2. Check safety devices<\/h3>\n\n- Test smoke detectors (and replace batteries if needed).<\/li>\n
- Test carbon-monoxide detectors, especially if you have a fireplace or combustion appliances.<\/li>\n
- Make sure you have at least one accessible, functional fire extinguisher.<\/li>\n<\/ul>\n
3. Prepare for power outages<\/h3>\n
Power outages are part of winter reality. A small emergency kit makes them far easier to handle:<\/p>\n
\n- flashlights and spare batteries;<\/li>\n
- a few extra blankets;<\/li>\n
- bottled water and non-perishable food;<\/li>\n
- a portable phone charger.<\/li>\n<\/ul>\nInfo box \u2013 Real-estate perspective:<\/strong>
