Burst Pipe Prevention, Insulating and Weather Proofing Your Home for Winter
This article gives you some common sense tips on keeping your home snug and warm in the winter. It also provides information on how to protect your home and yard from cold, wind, rain, and snow.
What Does Insulation Mean?
Insulation is any material that reduces the rate of heat transfer. For instance the handle on a saucepan is insulated so you don't burn your hand. Metal is good at transferring or conducting heat, so usually saucepan handles are made from wood or plastic to stop heat conduction. In the context of a building structure however, insulation is a material that is used to stop heat flowing out through the walls, ceiling and floor. Usually this is in the form of boards with an insulating foam layer, or layers of fleecy material such as fibre glass, rock wool or sheep's wool. If rooms are well insulated, once they're heated, they hold the heat for longer and it doesn't leak out so fast.
How to Keep the House Warm
- If you can afford it, try to upgrade the insulation in the house. Most heat is lost up through the ceilings into the loft and out through the roof. The space between the joists should be insulated with 4 inches and preferably 8 inches of fibreglass or rock wool insulation.
- Inner walls can be insulated with rock wool and finished with plasterboard (drywall), or plasterboard backed with foam insulation may be used.
- Cavity walls can be drilled and a foam insulation pumped into the intervening space.
- External insulation is also an option. Multilayer sandwich panels consisting of insulation, a water permeable membrane and an outer painted finish can be retrofitted to exterior walls. Some contractors render the finished insulation when it is installed.
- Single glazed windows should be upgraded to double or triple glazed units.
- Boilers should be serviced to ensure they are working correctly, the flue is clean, fuel is being burnt thoroughly and they are working at top efficiency. Circulating pumps can become stuck during the summer so this needs to be checked out.
- Chimneys of open fires need to be cleaned to remove soot and creosote deposits or leaves from overhanging trees. Guards should be fitted to the chimney pots to prevent birds setting up residence the following spring.
Exterior House Maintenance
- Gutters and down pipes need to be cleaned to ensure proper drainage from roofs, but wait until the leaves have fallen off all nearby trees or you will have to do the job again later!
- Remove any moss or leaves which accumulated in the valleys between apex roofs.
- Ensure all brackets, nails and screws holding the gutters are secure.
- Check your downpipes are not clogged.
- Drips from overflowing gutters in the winter can form large icicles.
- Check gulleys for blockages from leaves and other debris.
Protecting Plumbing from Freezing
- Frozen and burst pipes are a common problem during freezing weather. All pipes which may be exposed to freezing temperatures should be lagged with insulation to prevent freezing. New pipe work should be buried deep enough in the ground to protect it from freezing.
- The cold water tank in the loft should be surrounded with a layer of insulation and the associated pipe work should be lagged. When the floor of the loft is insulated, this makes the loft colder and plumbing is more prone to freezing, so during extremely cold or snowy weather, the loft door should be left open to allow some heat from the rooms below to travel upwards.
- Ensure you know the location of all your gate valves / stop cocks inside and outside and their functions. Write their function on the wall behind them with a thick marker and obviously check they actually turn and aren’t seized. You don’t want to be trying to turn off a seized valve in an emergency when water is coming down through the ceiling!
- You can use pipe heating cable to stop pipes from freezing where pipes are exposed to really cold temperatures. This comes in the form of a tape or cable that you wrap around the pipe. The tape warms slightly when powered up. Newer versions of this tape are self-regulating so temperature doesn't become excessive.
Preparing for Ice and Snow
- Ensure you have adequate supplies of fuel. Oil, gas and electricity suppliers are competitive so shop around to get the best deal.
- Get a good quality snowblower, snow or grain shovel for clearing snow from pavements and driveways. A blade made from aluminium is lighter than a steel blade.
- Clean moss from pavements with a proprietary cleaner or power washer.
- Stock up with salt and grit for defrosting snow and ice on pavements.
- Gutters should have adequate brackets to support snow load as snow starts to thaw and slide down roofs.
- Drain hoses to prevent them freezing and bursting.
- During thunderstorms which can occur during blizzards, unplug all electrical appliances and landline equipment such as modems and phones and use your cell phone for communication.
- Stock up with torches and a camp stove in case there are power failures.
- Get some storage containers which can be used to hold water in case the water supply pipes freeze and the supply is interrupted.
Protecting Garden Plants from Frost
- If possible, bring vulnerable plants in containers which could be damaged by frost, inside or into a frost free shed. Wrap bubble wrap or straw around larger plants or plants in the ground
Coping with Electrical Power Outages
- If you have a generator, make sure it works properly, the oil level is ok and it starts up without difficulty. Test it under load to see if copes ok without struggling.
- A freezer will maintain low temperature for several hours if it is not constantly opened.
- A portable gas stove can be used for heating and cooking.
- The backup batteries in your alarm panel and bell/sounder have a limited lifespan so replace them at the required interval.
