When it comes to looking after your home, gutters and downpipes might not be at the top of your to-do list. But keeping your rainwater system in good condition can help prevent water from overflowing, causing damage to your home and creating bigger problems further down the line.

With autumn bringing falling leaves and winter often bringing wetter, stormier weather, now is a good time to give your rainwater system a little attention. Dave Osborne, Technical Manager at Swish Building Products shares his top tips on how to keep your rainwater system in perfect working order throughout the colder months.

Check your gutters regularly

One of the simplest things you can do is keep an eye on your gutters, particularly after heavy rain, strong winds, and storms.

Leaves, twigs and other debris can collect in gutters and eventually cause blockages. If water can't flow freely, it may overflow or back up into areas where it shouldn't be, potentially causing damage to your home.

Look out for:

• Leaves and other debris building up
• Water sitting in the gutter
• Gutters that appear to be sagging
• Cracks or damaged sections
• Leaking joints
• Loose brackets or fittings
• Water overflowing during rainfall
• Water running down the outside of the gutter or behind it

Catching these problems early can make them much easier to fix — and could help avoid a more expensive repair later.

What should you do if your gutters are blocked?

If you find a build-up of leaves or debris, it should be removed sooner rather than later. Once the gutter has been cleared, you can check that water is flowing freely through the gutters and downpipes.

It's worth remembering that prevention is better than waiting for a blockage to become a problem. Checking your gutters regularly and clearing debris before it builds up can help keep the system working properly.

For homeowners looking for an extra way to help prevent leaves and twigs from entering the downpipe, a gutter balloon, which helps stop debris from getting into the downpipe in the first place, is a practical option.

Be careful when cleaning

Gutter maintenance can involve working at height, so safety should always come first. Make sure you have suitable access equipment and know how to use it safely. If you're not confident working at height, it's best to get help from a professional.

When cleaning gutters, don't simply wash everything down the downpipe. Leaves and other debris should be removed where possible and disposed of appropriately.

If you come across oil, chemicals or other pollutants, take extra care to prevent them from being washed into the drainage system.

Don't wait for a storm to find a problem

Our weather can put a lot of pressure on a rainwater system. For example, heavy rain is now becoming the norm, meaning your gutters and downpipes have to deal with much larger volumes of water than they have done in the past.

A bigger rainwater system can help where increased capacity is needed, but it's not the only answer. Ensuring you have the right number of downpipes, which are positioned correctly can also help manage larger volumes of water. There are many resources available, such as our Technical Hub, to help you calculate the correct number of downpipes for your home. If you’re unsure, talk to your local supplier or installer who will be able to provide practical advice and guidance.

Most importantly, a system needs to be well maintained to perform properly. A gutter that's partially blocked, damaged or poorly aligned may cope with light rain but struggle when a heavy downpour arrives.

Checking your rainwater system before periods of bad weather can therefore give you an opportunity to spot and address problems before they're put to the test.

Remember to look beyond the gutters

Your rainwater system doesn't stop at the bottom of the downpipe.

Underground drainage and soakaways also need to be able to carry water away from your home effectively. If there's a problem further down the system, water may not drain away as it should and could potentially back up.

So, if your gutters appear to be working properly but you're still experiencing drainage problems, the issue may be further downstream.

What about older gutters?

If your home has an older rainwater system, it doesn't necessarily mean you need to replace everything.

Instead, look for individual parts that may have started to deteriorate. Cracked gutters, damaged fittings, worn seals, loose brackets and leaking joints can often be identified during a routine inspection.

It's also worth looking out for signs that the system is gradually becoming less effective. An older system may appear to work perfectly well when it's raining lightly, but problems can become much more obvious during heavy rainfall.

Where the rest of the system is still in good condition, replacing individual damaged components can be a practical way to keep it working effectively without replacing the whole system.

 Check before you replace

If you do need to replace a gutter, fitting or downpipe, make sure the new component is compatible with the existing system.

Different rainwater systems can have different profiles and fitting designs, so components aren't necessarily interchangeable. Using compatible products can help ensure everything connects and seals correctly, reducing the risk of leaks.

A few simple checks can make a big difference

Looking after your rainwater system doesn't have to be complicated. A quick inspection a few times a year — particularly after severe weather and during autumn leaf fall — can help you spot problems before they become bigger issues.

Keep gutters clear, check for damage, make sure water can flow freely and don't forget the drainage below ground. A little regular maintenance can go a long way towards keeping rainwater away from where you don't want it.
