Modern plastic guttering is a high quality, lightweight, flexible, and easy-to-install product. There are however some important points to take on board when carrying out a guttering replacement.
Firstly, whilst removing old plastic guttering is a relatively straightforward task, stripping out old cast iron guttering requires a lot more care and effort. It is recommended that long nails are hammered into the fascia board immediately under each section of guttering as it is very heavy and will require support once disconnected. The bolts connecting the ends of each section should then be cut through with a hacksaw and each section carried down by two people (one at each end) using rope loops.
Once the old guttering and brackets have been removed, installation should always begin by fitting the guttering piece with the drain outlet, using a plumb line from the fascia to the drain below to accurately mark the position. The outlet piece should then be fitted no lower than 50mm below the roof line.
It is vital that the guttering along each wall is fitted so as to slope downwards towards the drain outlet at a gradient of approximately 10mm for every 6 metres of guttering. The best way of ensuring this is to fix a bracket at the opposite end to the drain outlet and to connect an accurately loping string between the two.
The positions for the remaining brackets should then be marked at intervals no greater than one metre.
