If you plan to carry out this work yourself, plastic guttering is often the easiest type to fit. In this blog we are going to take you through step-by-step on how to replace your guttering.
Most importantly, before we start, guttering is often a high level off the ground and will require the use of a ladder. Please place your ladder carefully, not too close to the wall itself, and if possible have someone hold the base of the ladder when you are on it. Never reach too far from your ladder so you don’t lose your centre of balance, always take the time to come down slowly and move it further along the wall if you need to reach further.
Old Plastic Guttering
Old plastic guttering is relatively easy to remove: simply cut through the bolts that are joining your sections of gutter together and gently tap them out using a hammer and unscrew any brackets that are holding the guttering in place. Before you start affixing new guttering, make sure you are working with a clean canvas by sanding away any flakiness or unevenness on the house where the gutter is to be fitted.
When you are ready to start replacing your guttering with the new product, the first step is to fit a gutter bracket at the top end of the fascia board and mark the positioning against the fascia with a pencil. Then fit the gutter outlet no more than 50mm below the level of the roof tiles: you’ll have been provided with advice upon purchase about the size and number of screws to use, so make sure you follow this advice closely.
From where you have secured the bracket, stretch a piece of string along the fascia board to the outlet, using a spirit level to check that the string is sloping towards the outlet – as this will ensure the water will definitely run this direction and drain efficiently. Once your string is sloping to the degree you are happy with, it is time to start positioning the other brackets along the fascia. Try to place them no further than 800mm apart from each other and no more than 150mm away from any joints or fittings, so as to make sure they have enough support. If you live in an area with heavy rainfall, you will want to make sure your brackets are closer together and no further than 400mm apart. Your outlet will most likely be at the end of the gutter, however if it is in the middle, ensure to repeat these same steps at the other side, once again ensuring that the downward slope towards the outlet is accurate.
When all brackets have been fitted, fit your stop end to the first length of gutter and clip everything into position by tilting the gutter to fit under the back clip and straightening it under the front clip. As each length is fitted, keep joining them in a similar fashion. You’ll notice on your guttering that there will always be a ‘depth mark’, and it is important you pay heed to it and do not go past this marking. Plastic guttering will expand and contract depending on whether it is hot or cold, this depth marking is to allow for such fluctuations.
When fitting each length, you will need unison fittings to keep each length attached. Cut the last section with a hacksaw when you have reached the end of your board and attach your final stop end. You will then proceed to fit the downpipe of your guttering – make sure this is positioned directly over the drain on the ground.
It is vital when replacing your guttering that you pay close attention to the guidance that comes with them. This is because there is quite the variety of guttering on the market and each will come with different specifications. Poorly fitted guttering that does not have enough support or does not slope to the correct angle could not only damage your fascia boards, but it will also be rendered useless when it cannot perform its primary function of draining water.
