Guttering in Knebworth

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.

You don’t always need scaffolding to replace guttering. If your home is a bungalow, the tradespeople might only need a ladder to replace your guttering. It’s when your home is two storeys or more that scaffolding is more necessary.

You might not need full scaffolding for a simple two-storey home. Guttering specialists use scaffold towers, which are the platforms you see underneath the scaffolding, where the installation is relatively straightforward. You might need scaffolding to replace guttering when there are obstructions to towers being used – for example, if you have a conservatory or the ground is very uneven. It's more likely that specialist roofline companies will use scaffold towers when necessary. Sole traders that replace guttering as part of their services may be comfortable using sturdy ladders.

There’s no legal requirement to say that you must have scaffolding when fitting guttering, but it is a good idea when working on homes rather than bungalows. If you’re unsure whether you need full scaffolding for your gutter replacement project, get a few quotes from reputable businesses of different sizes. If you’ve been quoted by one company that you need full scaffolding whereas everyone else says that only towers are needed, it’s likely that the job is perfectly safe to carry out with just towers.

You don’t always need to replace your gutters with your roof. Often people think that it’s a requirement, or simply the best thing to do, but it’s not always necessary. The reason why people think it’s required is because to re-roof a home, the guttering often needs to be removed and put back on.

If the time has come to replace your roof, then the chances are that your guttering is pretty old too. When you start to get quotes for your roof replacement, ask the roofer to take a look at your guttering as well. If there are signs of peeling, rust, cracks or sagging, then it makes sense to replace your gutters with your roof. If you get them done at the same time, you’ll save money labour costs, which is the reason why most homeowners do it.

Another reason to replace your gutters with your roof is the risk of damage. Re-roofing is a significant project, so the guttering needs to come off most of the time – running the risk of brackets and pipes getting damaged in the process. So if your guttering is still looking good right now but you think it might need replacing in a couple of years, it might be worth just doing it at the same time as your roof to save you money and the stress if damage does occur.

However, if your guttering has only recently been replaced, then there’s no need to replace it again with your roof. But because it needs to come off, make sure you speak to the roofing company about keeping it safe and doing their best to avoid damage. It’s also worse ensuring that they have the correct insurance to cover you both in case your guttering does get damaged during your roof replacement.
