How much does it cost to install a gutter?

At the beginning there is of course the question of whether the installation of a gutter is really necessary: ​​You can seal and repair small leaks or cracks in the gutter. However, if your old gutter is largely broken, you should replace it as soon as possible. If you have built a new one, the installation of the rain gutter is one of the tasks that you can do well on your own and thus reduce the construction costs somewhat.

The installation of a rain gutter is also recommended for garden houses, carports and garages. Otherwise there is a risk of water damage in both cases - and it can be expensive. Because gutters drain the rainwater through a downpipe and thus protect the walls from moisture. If the gutter is missing or damaged, the water runs down the walls unhindered. Moisture damage is programmed.

Fitting the gutter: which material is used?

You can choose between plastic and metal gutters for gutters. Plastic gutters are easy to handle, resistant to UV light and weather, flame-retardant, dimensionally stable and comparatively cheap. Plug systems from the hardware store make assembly using the do-it-yourself process particularly easy. However, the lifespan of a plastic gutter is limited. Depending on the product, it can last around ten years if it is installed correctly. After that, the first signs of aging can be expected. Smaller holes and cracks in the gutter can be sealed and repaired.

In comparison: metal gutters easily last 25 to 30 years. However, the cost of metal gutters is also higher. They are particularly resistant and dirt-repellent. The material looks better than plastic, but is a little more difficult to assemble. Metal gutters can also be glued or soldered to close leaks or repair defective areas.

Fitting the gutter: step-by-step instructions

1. Planning

Before you get to work, you should carefully consider whether you want to install the gutter yourself or commission a specialist company. Since the rain gutter must be tight and tight in any case, precise work is essential. In addition, clarify the following questions: Where must the gutter be installed? Can you reach the job with a ladder or do you need scaffolding? Is it perhaps enough to replace only a section and to solder it to the existing gutter? What dimensions must the gutter have?

2. Material

If you install your gutter yourself, it is comparatively easy with plastic: You can get connector systems for different roofs in the hardware store. These complete systems come with their own assembly instructions, which may vary slightly depending on the manufacturer.

3. Tool

  • Ruler / tape measure
  • Guideline
  • possibly cordless hammer drill
  • Jigsaw or saber saw with universal saw blade
  • Screwdriver / cordless screwdriver
  • Sandpaper / file
  • hammer
  • Tin snips
  • Water pump pliers
  • Site manager / scaffolding
  • Spirit level

4. Preparation

In the case of tall buildings, you should first set up scaffolding. You can borrow this from specialist companies. For lower houses or corresponding experience, a construction manager also does it.

If you want to equip a garden house, carport or garage with a gutter, first check whether they already have a longitudinal batten for hanging. If not, attach them now.

A scaffold is much safer than a ladder. No matter whether you work on the gutter on the house or in the garage.

5. Remove the old gutter

First remove the lowest roof tiles. To be able to remove the old gutter, you have to get to the gutter bars. These are semicircular brackets that support the gutter and are usually under the tiles. Bend the thin metal tabs on the inside and outside of the gutter iron and remove the gutter. You can also cut the old gutter into several pieces beforehand using a hacksaw or powerful tin snips - this makes it easier to remove. If the gutters are still in good condition and fit the new gutter, you can easily reuse them. Advantage: They are already installed in the correct position and with the right slope.

6. Install the new gutter

The gutters - the brackets for the gutter - are usually attached to the eaves board with wood screws. This is the name of the end board, which is attached to the top of the lower rafter ends. First mark the position of the gutter drain, the so-called clip, on the eaves board. This will be the lowest point of the new gutter. Mount the first gutter to the left of the drain and a second one to the right. The third gutter becomes the highest point of the gutter at the other end. Note that the slope should be about 3 centimeters for 10 meters of gutter. The absolute minimum is 1 centimeter drop per 10 meters. Use a spirit level and stretch a guide line to attach the other gutters at a distance of about 50 centimeters according to the slope.

In the case of hipped roofs, the rain gutter is usually installed all round and has only one drain - here you have to install four corner pieces in addition to the gutters and align the overall slope so that the highest point is at the opposite corner of the building. You should tend to work with a minimum gradient of one centimeter, otherwise the height differences will be too great.

7. Check stability

Before you use the new gutter, first check once again that all brackets are really well seated. If necessary, readjust with a water pump pliers to bend the gutters according to the slope. Tip: If you use adjustable gutters, you can easily bring them to the correct height using the screw rail. In the case of a plastic gutter, now place the sections of the gutter in the holder and connect them with special connecting pieces - they are simply used with the semicircular sleeve plugged in on both sides - there is a rubber seal that ensures that the water does not run out. Lay metal gutters with an overlap of around one centimeter and then solder these seams.

No matter what material you use: you may also need to cut some elements at this step. At the beginning and end of each gutter, attach the end pieces and insert the segment with the gutter drain.

8. Downpipe assembly

Put the upper end of the downpipe bend on the drainage pipe of the gutter and bring the bend into the correct position. Then measure the required downpipe length from the lower end of the bend. Now take a spirit level and guide line again to mark the course of the downpipe and the installation points of two to three fixed clamps. You need a fixed clamp at the top and bottom of the pipe at least, which, depending on the material, is attached to the house wall with dowels or directly with the screw thread. If you have a long pipe, you should include an additional one in the middle. Basically you need a pipe clamp approximately every two meters. Now cut the downpipe to the correct length, assemble it and fix it in the clamps.

9. Connect metal gutters

In order to ensure the tightness of the rain gutter made of zinc or copper, you have to solder all connections in a final step. Two different soldering methods are used, depending on the material, the brazing or soft soldering method. You can find out how to proceed in our instructions for soldering gutters. By the way: Nowadays, metal gutters are increasingly glued instead of soldered. When properly designed with additional blind rivets, the connections are just as stable and durable.

Tip: To keep your gutter in good shape for a long time, it is advisable to attach a special gutter protection against leaves and blockages. Various systems are commercially available for this.

How much does it cost to install a gutter?

When installing gutters, you have to differentiate between material and labor costs. With plastics, you can expect an average of 4 to 5 euros per meter of material costs for gutter and downpipe. Zinc costs around 13 euros. The price for a copper gutter, however, is around 20 euros and more. There are also brackets and fittings. If you commission craftsmen to install the gutter, this will cost around 5 euros per meter on average for plastic gutters. If the zinc gutter or copper gutter is to be soldered, depending on the soldering method, you should also plan with around 2 to 3 euros per meter. You can get a scaffold for an average of 600 to 1, 000 euros. And of course the dismantling and disposal of your old gutter has a price. The average cost of a 40-meter gutter is as follows:

  • Remove and dispose of the old gutter: around 300 euros
  • Material costs plastic: about 200 euros
  • Installation costs: 150 to 200 euros
  • Total costs: around 650 to 700 euros
  • Remove and dispose of the old gutter: around 300 euros
  • Material costs: around 500 euros
  • Assembly costs: around 200 to 250 euros
  • Total cost: around 1, 000 euros
  • Remove and dispose of the old gutter: around 300 euros
  • Material costs: from 800 euros (depending on the spot price on the copper market)
  • Installation costs: 250 to 300 euros
  • Total copper costs: from around 1, 300 euros
