Guttering in Kensington and Chelsea

A gutter is part of the system that takes rainwater away from a building. Every home will have some form of guttering system to stop water from dripping off the roof and into the walls. It’s important to keep your gutters clear because if water starts to seep into your home’s walls, you’re likely to get damp.

A guttering system consists of half pipes, troughs, bends and downpipes. They’re usually cylindrical in shape but they may be square on some homes and in countries outside of the UK. Technically, the gutter is the part that you’ll see across your roof that collects rainwater. The water will then feed into a downpipe from your roof’s edge to the base of your home, where you can collect it in something like a water butt, or it will be discharged to a surface water drain or soakaway.

In early times, gutters used to be made from lined wood or stone. Lead was often used as the liner to stop rainwater from seeping through the material, but you won’t see it used much anymore. These days, most homes have uPVC guttering as it’s a hardwearing plastic that should last a long time. But you’ll also see gutters made from aluminium, cast iron and copper, especially on period homes or those in a conservation area.

Every home needs a guttering system to ensure that rainwater doesn’t affect the foundations of the property. It’s also important to keep the gutters clear of debris like fallen leaves, as this will cause them to overflow, potentially causing water to soak into the walls and causing damp.

1. Hang a plumb bob from the outlet to the drain to use as a guide while you draw several marks on the wall with a pencil to show you where the downpipe will run.
2. Join the marks up with a straight edge, creating a line to show where the centre of the downpipe will be.
3. Position a downpipe clip at the top of wall, in the centre of the pencil line. Mark the position of its fixing holes on the wall. If you need an offset bend, put a downpipe clip directly below the bend.
4. Repeat the process down the wall. Make sure there is no more than 1.8 metres between pipe clips.
5. Refer to the guttering manufacturer’s instructions to see which drill bit is required. Use a drill to drill the fixing holes and insert wall plugs.
6. Fit the first piece of downpipe starting from the outlet and moving towards the drain.
7. If you need to add more downpipe, join the two pieces with a pipe socket and clip. Leave a 10mm gap between the end of the pipe and the bottom of the pipe socket, because it will probably expand. Then attach a pipe clip over the joint.
8. Continue attaching pipe clips down the length of the downpipe.
9. If you need to, fit a downpipe show to direct the water into the drain. Attach a downpipe clip directly below the socket of the shoe.

In the UK, gutters are normally made from uPVC. It’s a hardy plastic that won’t rot, warp or tarnish very easily, which is why it’s so popular. It’s the same material that’s used for most homes’ windows these days; they don’t have to be the standard white as they can be made into a range of colours. Expect to pay an average of £500 for the supply and installation of uPVC guttering, and more if you require scaffolding.

Other materials that are popular for gutters include copper, aluminium and cast iron. These are much more expensive – you might be looking at around £1500 or more for the supply and installation – but they give a more polished look and are often used on period properties or those in a conservation area. If you're considering these types of gutters, make sure you get a few quotes from different roofline companies so you can compare the different materials.

In the past, gutters were made from wood, asbestos concrete or stone. They were often lined with lead to stop the water from seeping through. When it was discovered that asbestos was seriously harmful, it of course stopped being used. Wood was prone to rotting, even with lead lining, and stone is heavy and expensive. So when uPVC came along, it became an affordable and easy material to use for gutters so homeowners could be confident that rainwater will be kept away from the foundations of their properties. It’s important to keep gutters clear from leaves and debris, because if they become blocked, they can make water to fall against your property’s walls, causing damp.
