Winter Safe Home: A Checklist for Homeowners & Landlords

Winter is coming and with it comes freezing temperatures, blustery winds and the occasional surprise snowstorm. For homeowners and landlords alike, the cold season can reveal weak spots in a property and sometimes in the most disastrous way – from draughty doors to burst pipes. 

Preparing your home before the worst of the weather hits is essential for avoiding costly repairs later down the line and it helps to keep everyone safe and snug too. In this friendly guide, we’ve put together a winter home preparation checklist for homeowners with some additional tips for landlords – plus we’ve sprinkled in some expert tips on winter-proofing doors. 

Let’s get your property winter-ready!

Winter Preparation Checklist for Homeowners

Homeowners have the advantage of being in full control of their property’s upkeep. Tackling these home improvement tasks before and during winter will mean your house remains warm, safe and efficient throughout the colder months. So lets dig in…

Service Your Heating System

Schedule an annual service for your boiler before the deep freeze sets in. A professional tune-up keeps your heating running efficiently and safely, preventing that inevitable breakdown on the coldest day of the year because the universe is determined to conspire against you. 

Replace or clean filters in forced-air systems and bleed radiators if you have them, this will help to remove any trapped air and improve heat circulation. Remember, a well-maintained heating system not only keeps you cosy but also reduces the risk of carbon monoxide issues and saves on energy bills. It’s a no brainer for winter really.

Protect Your Pipes from Freezing

Burst pipes can be a huge nightmare in winter, often leading to thousands of pounds worth of damage, so prevention really is better than cure in this instance.

Insulate exposed water pipes in unheated areas like lofts, garages or crawl spaces with foam sleeves. If you’re away or overnight temperatures plummet, keep the heating on at least at a low setting (around 12–15°C minimum) to make sure interior wall cavities stay above freezing. It’s also wise to know where your main water shut-off valve (stopcock) is located as you may need to turn off water quickly if a pipe does leak or burst. A bit of foresight, a few quid spent on pipe insulation and minimal heating can save you from the huge mess and expense of frozen pipes later down the line.

Seal Doors, Windows and Floors

Don’t let the warm air literally slip through the cracks. Check for gaps or draughts around doors and windows and seal them to stop cold air from sneaking in. You can install weatherstripping around external door frames and use caulk or sealant for window gaps. You could also do some DIY double glazing using window film to guard against chilly draughts and heat loss if your old windows no longer cut the mustard.

Adding a simple door sweep (a strip at the bottom of the door) can block cold air under exterior doors too. Even your letterbox can be a source of heat loss so consider adding a letterbox draught excluder if you don’t already have one.

Floors can often be an overlooked source of heat loss too, bare wood floors are notorious for being draughty, but there are a number of ways you can insulate floorboards that don’t break the bank. By sealing these little gaps, you’ll keep your home warmer and potentially cut down on heating costs. For bonus cosiness, use thick curtains or thermal blinds at night to further insulate your windows and add rugs to rooms with bare wood floors.

Check the Roof and Gutters

Your roof and gutter system are your home’s first line of defense against winter weather.

Before heavy rain or snow arrives, inspect the roof (or hire a pro) to look for missing tiles, loose flashing or any signs of damage. Clear out blocked gutters and downpipes of leaves and debris so that winter rain and melting snow can drain properly. Clogged gutters can lead to ice dams (chunks of ice that block water) which may force water into your home and cause damage, which can become costly. 

Likewise, make sure downpipes are firmly attached to the rest of the guttering and direct water away from the foundation to avoid pooling water around your house. Taking an afternoon to clean gutters and check the roof can help prevent major leaks and water damage later down the line.

Make Sure There’s Adequate Insulation

Obviously a well-insulated home stays warmer for longer with less energy use. 

Firstly, check your loft insulation levels. Heat rises and the last thing you want is for the heat you generate to just disappear out of the top of your house due to poor insulation. In the UK, about 270mm of insulation material is recommended in the loft. If your insulation is thinner or has gaps, consider topping it up to reduce heat escaping through the roof. Also, insulating hot water tanks and pipes helps retain heat. Don’t forget to close and insulate crawl space vents if you have them, to keep cold air out of those areas too. Proper insulation not only keeps your living space warmer and you more comfortable but also prevents issues like ice dams on the roof by keeping attic spaces cooler.

Test Safety Devices

Winter means we seal up our homes and crank up the heat, which makes smoke alarms and carbon monoxide detectors more crucial than ever. Double check that you have working smoke alarms on every floor and at least one carbon monoxide detector, especially near sleeping areas and any fuel-burning appliances, like a boiler or fireplace. 

Test these devices monthly and replace batteries as needed. Remember that a poorly maintained boiler or blocked chimney can produce carbon monoxide – an odourless, deadly gas – so detectors really are lifesavers. If you use a fireplace or wood burning stove, have the chimney cleaned and inspected to prevent creosote buildup and chimney fires too.

Prepare Winter Essentials

Don’t wait for a snowstorm forecast to stock up on supplies. We’re not suggesting going full on prepper survival mode, but keep a bag of grit or ice salt handy to sprinkle on slippery driveways and footpaths. Maybe keep a snow shovel handy too, especially if you live in a higher, more exposed location where drifts can be more common.

And while it’s not usually a major problem in the UK, it’s also smart to prepare an emergency kit in case of winter power cuts or being snowed in because you just never know, especially if you’re in a more remote area. Include a couple of torches with spare batteries, a portable phone charger, blankets and maybe some non-perishable food and water. That way you’ll be ready for winter surprises and can stay safe even during a cold-weather emergency.

By checking off these items, we’re sure homeowners can rest easy knowing their house is as winter-proof as possible. You’ll stay warm, save on energy and prevent many common winter mishaps before they start!

Winter Preparation Checklist for Landlords

Landlords have a dual responsibility in winter: protecting the property and keeping tenants safe and comfortable. Many tasks overlap with general home maintenance, but there are extra steps you’ll need to take to make sure your rental property meets legal standards and the tenant needs during the colder months. 

Here’s how landlords can get their rental properties winter-ready:

Keep the Heating System in Top Shape

A landlord’s worst nightmare is a boiler breakdown on a freezing night. To avoid that service your boiler annually, ideally before winter begins, by a qualified engineer. In fact, UK law requires an annual Gas Safe check on gas boilers and any other gas appliances. Early servicing spots issues before they escalate and it’ll keep the manufacturer warranty intact if you still have one.

Also, check all radiators: bleeding them can fix cold spots, improve efficiency and prevent condensation (which can be a whole problem in itself). Make sure the thermostat is working and easy for tenants to use too, so they aren’t left fiddling in the cold. A little proactive maintenance goes a long way to making sure your tenants stay warm and your heating system runs smoothly all winter.

Inspect the Exterior of the House 

Before winter really settles in, do a thorough inspection of the property’s exterior, as you would your own home. Check the roof for any loose or missing tiles, broken tiles or damaged flashing, since these can let water in during rain or snow. Clear out the gutters and downpipes to make sure rain and melting snow can drain away properly.

Also make sure that ground drains aren’t clogged and the brickwork is intact. Blocked gutters can overflow and poor brickwork with disintegrating mortar can lead to leaks in walls or ceilings which can cause damp and mould, so it’s important to address them before they become a major problem.

Pay extra attention to flat roofs if the property has them, as they’re more prone to leaks after heavy rain or ice. Staying on top of roof and gutter maintenance will protect your investment and prevent mid-winter repair emergencies.

Tackle Damp and Condensation

Cold weather often brings problems of dampness and mould, which can affect your property and your tenants’ health. To prevent condensation build-up, make sure the property is well-ventilated, the easiest way to do this is to install extractor fans in the kitchen and bathrooms and make sure they’re effective. Advise tenants on simple habits like opening windows for a few minutes daily (even in winter) to let humidity out and avoiding drying clothes on radiators without ventilation.

In any spots prone to condensation (like bathrooms or corners of exterior walls), consider using mould-resistant paint. It’s also wise to remind tenants not to push furniture right up against external walls as a little gap allows air to circulate and prevents damp patches. Remember, landlords are legally responsible for resolving damp and mould issues caused by structural or ventilation problems. Not sorting the problem early could mean your tenant has the right to seek compensation, so it’s far better to be proactive and prevent dampness than to deal with a mould outbreak later.

Verify Safety and Compliance 

Winter is a great time to double-check all safety measures in your rental. Test all smoke alarms (there should be at least one on every floor) and carbon monoxide detectors, and replace batteries or units as needed. Check any fire extinguishers and fire blankets are functional and fit for purpose, and be sure to document these tests to comply with regulations. As we’ve mentioned above, make sure you’ve had your annual Gas Safe inspection for any gas appliances too and that you’ve addressed any issues brought to light.

It’s always a good idea to check that emergency contact numbers for your tenant are up to date, provide them with who to call (plumber, electrician, etc) in case of urgent problems and make sure you or your managing agent can be reached easily in emergencies.

These steps aren’t just about legal compliance, they go a long way to showing your tenants you care about their wellbeing and want to help prevent issues too. Leading nicely into…

Communicating with Tenants

Keep the lines of communication open. You want them to trust you and likewise, you want to trust they’ll come to you with any issues. Consider sending your tenants a friendly winter preparation reminder as the season starts. This could include tips on using the heating efficiently, instructions on how to report any issues like leaks or heating problems promptly and reminders about things like not turning the heat completely off in a cold snap.

As noted before, provide them with emergency numbers so they know help is available when they need it. Encourage tenants to notify you early about maintenance concerns – it’s easier to fix a small damp patch or a draughty window before it becomes a bigger problem. When tenants and landlords work together with good information, the home will stay in better shape throughout winter.

By following this checklist, we’re confident landlords can fulfill their duties and significantly reduce winter woes in their rental properties. Your tenants will appreciate living in a well-prepared, safe home and you’ll protect your property investment from winter damage – a win-win scenario!

Winter-Proofing Your Doors and Windows

We’ve touched on it already but it would be crazy for us not to explore it further… doors (and windows) deserve a special shout-out in winter home prep as they play such a significant part in how energy efficient your property is! 

Exterior doors are the biggest culprits for draughts, which can make your home chilly and hike up your heating bills. Here’s how to winter-proof your doors and keep the cold out…

Check for Drafts

On a blustery day, run your hand around the edges of your external doors (and windows too). If you feel a cool breeze or notice daylight seeping in around the frame, you’ve got a draught. Even a small gap can whittle away the warmth inside your home. One easy fix is to install weatherstrips around the door frame, these rubber or foam strips cost just a few pounds but can make a huge difference by creating a seal when the door is closed, blocking cold air.

For windows, use self-adhesive weatherstripping or caulk to seal any leaks or gaps. Taking the time to insulate doors and windows can make your home so much more comfortable in winter by keeping warm air in and cold air out.

Install Door Sweeps and Draught Excluders

The gap at the bottom of an exterior door is another place cold air loves to creep in. A door sweep is a brush or rubber strip that attaches to the bottom of the door to close that gap. Similarly, you can use a draught excluder – those can be anything from a simple rolled-up towel to a decorative “snake” – placed along the bottom of the door when it’s closed. 

These stop icy draughts from seeping under the door. Don’t forget keyholes and letterboxes too! You can install covers or flaps that block wind but still allow them to function. Sealing these little openings can make a noticeable difference in keeping your entryway warm. If it’s time to replace an old letterbox, our handy step-by-step guide can help.

Consider Upgrades if Needed

If your door is very old, warped or still feels cold and leaky despite your best DIY weatherproofing, it might be time to consider an upgrade. Modern composite or uPVC doors often have better insulation and sealing than old wooden ones, meaning they naturally keep out draughts and moisture. 

The same goes for windows. Double glazing is so much more energy-efficient than single panes. While replacing doors or windows is an investment, it can pay off in energy savings and comfort (and of course, Doors & More can help you find the perfect insulated door when the time comes!). For now though, even a quick fix like a snug door curtain can add an extra layer of protection on colder nights.

“Newer doors often come with multi-point locking systems and thermal core options, which are great for insulation and security. It’s worth investing in these features not just for peace of mind, but because they can make a noticeable difference in how warm your home stays during colder months.“

– Matt Shaw, Technical Director at Doors & More

Remember, weatherproofing your doors and windows is essential not just for warmth, but also for protecting your home’s structure. By keeping rain and condensation out, you prevent issues like wood rot, warping, or even mould caused by moisture ingress. Plus, a well-sealed door improves home security by ensuring it closes tightly. Spend a weekend on these door duties and you’ll literally feel the difference on the next chilly evening – no more icy draughts at your feet!

“People often forget that internal doors can also suffer in colder months too, especially in unheated spaces like utility rooms or garages. Swelling, sticking and warping are common when humidity levels rise. Choosing moisture-resistant materials and checking hinges and latches regularly can save a lot of hassle later on.“

– Matt Shaw, Technical Director at Doors & More

Internal doors are often overlooked when it comes to winterproofing, but they play a crucial role in keeping your home warm – especially those leading to colder spaces like garages, utility rooms or basement areas. These areas typically lack heating, so any gaps or poor seals around connecting doors can allow cold air to flow into the main living space. 

To prevent this, it’s worth checking for draughts and adding adhesive weather stripping or brush seals where needed to those too. For added insulation, consider upgrading to a solid-core door or fire door (which is a legal requirement in some cases) due to their construction they’re naturally insulating, which can help maintain a more stable indoor temperature and reduce heat loss through the colder months.

Winter Home Preparation

Staying on top of winter maintenance may require a bit of effort, but the payoff is a warm, safe home and peace of mind. Whether you own your home or rent one out, a little preparation goes a long way toward avoiding winter woes. 

So, grab that checklist and a cup of hot chocolate, and get your home ready to weather the winter in comfort and safety!
