How Much Does Guttering Cost?

Determining how much a gutter installation will costs is difficult as it is dependent on a wide range of factors - such as the quality of the materials used, the choice of gutter type and whether it is uPVC or cast iron metal, and the style and sizes you wish to buy - as some drains components are more premium brands and there is a wide selection with different prices to choose from. The quantity you will use is another a factor as some properties require significantly more or less - such as a terraced property while others such as detached properties require much more. Therefore building or home type is also a factor to consider.

Plastic on average is the cheapest form and will require fewer repairs due to its durability. Downpipe sizes normally comes in 4m lengths with a diameter of 68-160mm. The different colours do not usually affect prices.

A whole new home install will also require other building materials, accessories and fixings such as fascias, soffits and a bargeboard too which need to be factored into the costing and this without factoring in courier costs.

Based on this information and assuming you are buying only the materials, you will look to spend approximately £500 before any labour charges - and this usually includes getting the products to you.

How Much is it to Replace a Gutter System?

How much it costs to replace your drains system is also dependent on a number of things; such as whether small repairs are required or you are replacing the whole thing on your property.

On average the sort of money you will look to spend is approximately between £400 to £800 to replace your existing system and fixings. The material your gutter system is made from will also influence this price.

How Do You Install Guttering?

Any UPVC gutter and downpipe is very easy to install with only standard hand tools and no specialist equipment necessary. It is fixed to the fascia board using the fascia board brackets and sits close just above the soffit board and collects runoff diverting it to the underground system. Only a basic sort of screws or nails, sealants or adhesives, and fixings will be the only parts necessary to complete the job in good time and results.

For a more detailed explanation of how to install a guttering system - you can check our full guide here. However, if you'd like a quick overview - the process is broken down like this:

Which tools will you need to install guttering?

Don't worry about needing to buy specialist tools - installing a guttering system will usually just require:

  • A cordless screwdriver / drill (power tools are optional - but they will speed your job up a little)
  • A spirit level
  • A hacksaw
  • A pencil
  • A good quality silicone lubricant
  • Sturdy ladders
  • String

It's also essential that you have someone with you to help. Although the actual gutting work can usually be done by one person - you should always have someone with you when you're working at height.

Step 1

Guttering installations are a job that requires careful planning - as misalignments or errors in lengths can mean water problems in your home or a need to buy replacements!

Start your planning by carefully lining up the running outlet over the connection to your drain. There are ways to run an indirect downpipe if required, but it's always easier if you can position it over your drain to begin with.

Step 2

When you've worked out where the stop-end or outlet for your guttering should be placed, you'll need to mark the fascia to make sure it's around 50mm below your roof level. This will mean you've got enough 'fall' across the rest of the house to make sure water drains as it should.

Step 3

Fix the running outlet or stop end to the fascia board using the manufacturer's instructions and the appropriate fixings. Be careful not to over-tightened any of the fixings as the plastic you're working with is quite soft.

Step 4

Now, working at the other end of the gutter run, you should measure to allow for around 1mm of fall across ever foot - around 3mm for every meter. For example, if you full run of fascias is 20ft (6m) then you'll need to position your first bracket 18mm higher than the running outlet - and around 100mm from the end of the fascia.

Step 6

Now, using your piece of string, you should tie a taut line between your first bracket and the running outlet. This will allow you to mark accurately the points needed for your additional brackets - so you can predrill pilot holes to mount them. You should aim to place brackets around 3.3ft apart - that's around 1m. You'll also need to allow for brackets within 150mm of bends and angles too.

Step 7

Now you can begin putting your guttering parts into place. With your gutter brackets in place, your gutter runs will simply snap into the brackets. Slide the length of gutter in at the back, then snap the front into place under the clip on the bracket.

Step 8

Work your way along the fascia snapping your gutter lengths into place and using union brackets to connect additional lengths if required. Your silicone lubricant will help you locate everything without too much effort or pressure. When you get to the end, you can simply snap your stop-end into place.

Step 9 - downpipe

When your horizontal gutter parts are in place, you'll need to direct water to the property's drain (underground drain or channel drain). Fitting a downpipe to make this happen is fairly easy - as it will simply push into place in the running outlet.

As long as you've positioned your guttering outlet correctly, it will be a straight drop to your drain. Since there's no lateral pressure on your downpipe, you don't need to worry about positioning clips as frequently as your would with gutter runs - just every 6ft (around 2m) is adequate.

If you do need to create a guttering downpipe that works around features on your home, you can do so fairly easily using downpipe angles and bends. Again, these push-fit, so they're an easy job - just make sure you've chamfered the cut end of the downpipe to make a clean connection. You'll also need to make sure you use a bracket to support any connections too.

Finally, you can place a downpipe shoe on the pipe to finish it neatly and make sure your rainwater is channelled neatly into the drain! Guttering job done! Now your rainwater will run neatly into the drain or channel drainage as required.

How Do You Clean Guttering? DIY vs Professional Services

One way to clean your gutters and downpipe is to do it yourself - or you can hire professional cleaning services who use specialist technology designed to suck the debris out quickly.

If you choose to do this yourself, you will most likely require a ladder, some clothing that you don't mind getting dirty, gloves and someone to help you hold the ladder at the base. If you're at all uncertain - cleaning services aren't overly costly though.

Climb the ladder with someone holding it firmly at the base and once at the top, start working along the system cleaning the debris content out the area inside. This will require you to frequently climb down to move the ladder along as you work your way along the gutter.

To prevent guttering blockages reoccurring in future, they will need to be well maintained and it may be a good idea to install leaf guards, or hedgehog brushes (pictured below) to reduce the maintenance need.

How Do You Unclip Plastic Guttering?

To unclip your plastic gutter from your roof, simply pull the clip that is hooked into the gutter over and out.

As it is made from plastic, it will have some flexibility allowing you to do this and shouldn't break. Unhook all the gutter clips and then roll the gutter piece away from you and it should begin to slide out. Repeat this for the remaining pieces.

If you happen to break any of the gutter clips, replacing them is simple too as you simply unscrew the broken clip piece and screw in a new one in its place.

What is Guttering and how does it work?

Guttering diverts rainwater away from a roof and into the underground drain services. In the past, these were created using cast iron. Nowadays, however, uPVC guttering systems are the most common type found on roofs because of their simplicity of installation, long life, low maintenance, and low cost. There are a wide number of systems now available to choose from.

Different Types and Materials Explained

Gutters are often produced from aluminium-alloy, galvanised steel, stainless steel, concrete and more. Plastic is the most popular type due to its ease to install - whereas stainless steel is very costly and often difficult to work with.

Gutters come in a selection of profiles, colours and consist of gutter lengths, bends, gutter branch connectors, guttering support brackets, gutter unions, filters, gutter hopper, diverters, downpipes, rainwater harvesting methods and angled shoes in the bottom, etc. Each guttering style range will have these common components and fittings.
