Guttering in Belfast

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.

• 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!
