Guttering in Llantwit Major

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.

If you live in an average home with an average amount of guttering and you’re used to a bit of DIY, it’s relatively easy to replace gutters. But if you have a home that’s more than two-storey or you have guttering that’s more complicated, it’s best left to the professionals.

Lots of homes these days have uPVC guttering. uPVC is a hard-wearing plastic that will last a long time without much maintenance except your usual gutter clearing. It’s relatively light, so lots of people think it’s easy to replace uPVC gutters. If you live in a bungalow, you may be able to just use a ladder to take down your old guttering and replace it with new uPVC gutters, but if you live in a two-storey home it can be a bit more complicated. If you do attempt to replace your gutters yourself, make sure you’ve got a sturdy ladder that will comfortably reach the right height, and never rest it on the fascia or the guttering itself.

If you have cast iron or copper guttering, this is much heavier and bulkier than uPVC. Certainly don’t try to replace these on your own – make sure you have another competent DIYer to help you. Reputable roofline specialists will use scaffold towers to make it easier to handle heavy gutters and they will always work in pairs on this type of guttering, so make sure you have the right tools and equipment to work with.

Just because it’s easy to replace gutters, it doesn’t mean you should. It’s better to ask a reliable roofline company to help you, since they have the skills to fit guttering properly and have experience with working at height.

• A sturdy ladder
• Gloves and safety goggles
• A hammer and nails to secure your fascia so it doesn’t fall down mid-replacement
• A hacksaw – this will cut through uPVC guttering – just make sure you leave a margin of error with every cut you make
• Cable ties or rope to secure the existing gutters while you dismantle them, so they don’t fall off
• All the right fixings and brackets to secure the guttering
• An electric drill and/or screwdrivers

1. Add a gutter bracket to the top of the fascia board at the opposite end to the stop-end outlet, if you have one. Then tie a piece of string around the base of the bracket.
2. You’ll need to place the gutter outlet accurately over the drain. Hold a plumb line against the fascia directly over the drain, and mark that position with a pencil. Following the manufacturer’s advice on the number of screws to use, fit the gutter outlet no more than 50mm below the level of the roof tiles.
3. Stretch the piece of string you tied on the bracket along the fascia board, and tie it to the outlet. Make sure you check with a spirit level that the string slopes towards the outlet.
4. Mark the positions of the other brackets. They should be no more than 800mm apart, or 600mm if your roof is very steep. They also shouldn’t be any more than 150mm from a joint or fitting. Then fit the rest of the brackets.
5. Fit a stop-end to the first length of gutter and clip it into position on the brackets. At the other end, fit a union piece and screw it into the fascia.
6. Then fit the next length of gutter into it, and the next until you’re finished. Cut the last one to fit using your hacksaw before attaching a stop-end. Then make sure all the joints line up with the insertion depth marks on the fittings. Then you’re done!

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.
