The weather in Britain can be unpredictable and we often see extremes of cold and hot weather. But how can this weather potentially affect your home?
We’ve taken a look at the effects of extreme weather conditions, so you can be prepared.
1. Subsidence
Subsidence can be an issue after sustained periods of very hot, dry weather, particularly for those living in areas with clay soil.
This is because the ground expands with moisture and then contracts when it dries out, meaning that buildings can start to move.
If you notice cracks appearing in the walls, they could be a sign of subsidence.
For more information, read our guide on what is subsidence?
2. Snowfall
A significant amount of snowfall can actually be surprisingly heavy.
If it builds up on the roof of your house or in the gutters, it can then end up cracking the guttering pipes or creeping up under the roof.
This isn’t too much of a problem while it’s still frozen, but it’s a good idea to clear it if you can and if it's safe to do so.
As soon as the snow and ice starts to melt, the water can leak through weak spots in slates, tiles and roof lining, into your ceilings and even walls.
If it’s not a lot of water, you may not notice it at first, but it can lead to other problems like damp patches and mould which are much harder to get rid of.
3. Damp
Us Brits are used to a lot of rain, but spells of cold and wet weather can leave our homes susceptible to problems with damp.
There are three kinds of damp that might affect your home and cause major problems:
- Rising damp: Ground water coming up through a wall or floor causes rising damp. A damp-proof course or damp-proof membrane will usually stop it from causing damage, but if your house is older and doesn’t have one of these in place, you might notice peeling wallpaper or paint, damage to the plaster or skirting boards, and odd wet patches on the walls.
- Penetrating damp: Penetrating damp is caused when water leaks through the exterior walls and then spreads inside and across interior walls. The usual cause of this is structural issues, like broken guttering or roofing, cracks in rendering or brickwork, or leaky pipes.
- Condensation: This is the most common of the three, and generally happens in winter. A lot of steam is generated by showering, drying clothes indoors and cooking, for example, and this condenses on walls, windows and other surfaces, particularly when they’re cold. Make sure windows are opened regularly to ventilate the house and use extractor fans in the kitchen and bathroom to help with this.
4. Flooding
Flooding is more likely to be an issue during a milder, wet winter rather than a cold and snowy one.
Bad storms, prolonged periods of heavy rain and sudden cloudbursts all bring a risk of flooding.
If you live in a flood-prone area, there are a number of things you can do to protect your home from flood damage.
And regardless of where you live, it’s a good idea to make sure your guttering and drains are clear and not blocked by fallen leaves or other debris.

Storms and flooding can also damage old asbestos cement products such as rainwater gutters, down-pipes, soffits, wall panels and roofs causing them to either crack or break.
If broken pieces of asbestos cement products are found on the ground because of this, stop anyone from going near them, including pets.
Don't pick them up or put them in the domestic waste bin. You'll need to get further advice from an environmental health officer at your local authority or council who will be able to recommend asbestos specialists to remove and dispose of it safely.
5. Frozen pipes
When temperatures drop, the more exposed pipes in your home and garden are at risk of freezing.
If you have an outdoor tap, you may have already thought to ensure it is properly insulated, but what about those that might be in your attic or garage?
If the water freezes in any of the pipes in your home, it can cause the pipe to burst. You may not be aware that this has happened until temperatures start to rise and the ice in the pipe then melts.
Our step-by-step guide will help you prepare your home for winter so you don’t end up with frozen pipes.
