Why Replace Guttering

Defective rainwater guttering and pipework can be the source of many sorts of damp problems in the structure of a building. The guttering and associated pipework are designed to carry rainwater away from a building, if they are not properly maintained, the water can run down the outside wall, eventually causing damage within the structure, ruining the decoration and/or causing mould growth.

It is important to keep the guttering and pipework in good repair. The best time to have work carried out on the gutters is in the late autumn, after all the leaves have fallen - so you can clean them out of the guttering before they cause over winter problems. Often problems are only apparent while it is raining, so keep a lookout whenever it is raining for any rain water leaking from the gutters or running where it should not. If you notice any major leaks at any time of the year, treat the repair as a priority.

Why UPVC Guttering

PVC gutters are made from unplasticized polyvinyl chloride. The sections and fittings are lighter, easy to fix and do not require painting. Half round, square and ogee profile guttering and fittings are available. An ogee is a half-round adaptor used to join gutters of different profiles. Square gutters have a much greater capacity for carrying water than the half-round type.

If you need to replace part of the cast iron gutter, there are adaptors available to connect new PVC guttering to either half round or square cast iron guttering. It is important to replace any guttering with a type using a similar size channel. When the guttering is installed, its size is calculated to deal with the amount of water likely to come off the roof during a period of heavy rain.

If you choose a smaller channel of gutter, you could experience overflowing water damage at times of heavy rain. Larger channels are not a problem, but will be extra unnecessary cost. Most domestic rainwater installations use 100mm (4 inch) gutter widths and 62.5mm (2½ inch) downpipes. There should be a slight slope on the guttering leading to the downpipes. A 1 in 600 slope is ideal for guttering, measured from the base of the facia boards.
