Why Replace Guttering
Defective rainwater guttering and pipe work can be the source of many sorts of damp
problems in the structure of a building. The guttering and associated pipe work 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 pipe work 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)
down pipes. There should be a slight slope on the guttering leading to the down pipes.
A 1 in 600 slope is ideal for guttering, measured from the base of the facia boards.
