Guttering in Harrow

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 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.
