How to Protect Your Home and Business from Heavy Rainfall

Wet weather warnings and flood alerts seem almost commonplace nowadays in the UK – and the Chester/North Wales area is no exception. As we move from a rainy autumn to the coming winter, it’s a good time to consider the potential impact of all that water on our homes and business – in particular the impact on our plumbing and drainage.

Can heavy rain affect plumbing/drainage? Yes, it can. Heavy rainfall can either cause problems or make existing issues worse.

For example, if the ground becomes waterlogged the weight bearing down on pipes is increased, which can cause a pipe or joint to rupture. Also, if there’s a leaky underground pipe, excess moisture in the soil can work on the cracks and allow dirt and debris in, which can cause a blockage.

So, what can homeowners and businesses in Chester and North Wales do to ensure their properties are safe from the damage that heavy rainfall can cause? We have pulled together our tips, below.

Tips to protect your home or business from flooding

Regularly clear your drains and guttering

When drains or guttering are obstructed, the flow of water is either slowed or halted completely. This can result in the either collapsing due to the increased weight it carries or, alternatively, water can overflow and damage brickwork or breach seals on doors and windows. Get into the habit of inspecting your drains and gutters twice a year – spring and autumn are ideal – and promptly carrying out necessary maintenance to clear any obstructions.

Conduct an inspection of the local area

Regularly walk around your property and inspect downcomers and drain covers. In autumn, keep those areas clear from leaves, as they can obstruct the flow of water. After heavy rainfall, check to see if water is overflowing, pooling or running away slowly. If there’s a problem, take prompt action – drains can often be cleared using a pressure washer or outdoor vacuum.

Make sure seals are in good condition

Make sure the seals on doors and windows are sound, so that water doesn’t find a way in. It might come in as a torrent, in which case you know you have a problem, or seep in over a period of time. Either way, prevention is better than cure. If you have air vents in your external walls, it can be a good idea to cover those during bad weather, as they are another way that water can enter your property.

Ensure you have the correct insurance/cover

Flood insurance doesn’t come as standard so make sure, if you are at risk, that you purchase appropriate separate cover. You might also want to check what your existing insurance covers with regard to damage to guttering, plumbing, drains and sewers, and take out additional insurance if necessary.

Keep up to date with flood warnings in your area

The government makes information available that allows you to check not only if there’s an imminent risk of flooding but also whether there’s a history of flooding at your property or in the immediate area. Check GOV.UK regularly to stay informed.

Consider purchasing barriers

If you live in the Chester/North Wales area with a high risk of flooding, then it makes sense to have some contingencies in place – including sandbags or removable barriers for doors and windows. It might be possible to use the area around your property to help reduce the potential of flooding – keeping grassy areas or beds rather than having a lot of hard surfacing, installing French drains, and using levels in the landscaping can all help keep water away from the main property.
