Replacing Guttering

Planning
Regardless of the size of your guttering job, the following simple tips will make the project much easier.

Calculate the lengths of downpipe and guttering you require and complete the survey list of necessary components. When ordering, it is always better to over-estimate the lengths required than find yourself short half way through the job.

Fascia brackets must be no more than 1m apart. Running outlets, stopend outlets, angles, union clips and stopends need a supporting fascia bracket within 150mm of the fitting. Some are designed to be screwed directly to the fascia, but these still require support brackets within 150mm.

Removing the old guttering
The removal of old plastic guttering is relatively straight forward, but cast iron guttering should be removed using great care as it is extremely heavy and will probably have sharp edges.

If the screws are rusted into place, you will need to lever them off with a bar.

Fitting the outlet and brackets
The first step in fitting your new guttering is to fit either the running outlet in the middle of a gutter run or the stopend outlet at the end of a run to the fascia. This must be positioned directly over the drain position using a plumbline to ensure that it is lined up correctly. screw the outlet to the fascia, remembering that the far end of the gutter must be higher than the outlet by 10mm for every 6m of gutter.
The next step is to fit the end fascia bracket.

Check that the fascia bracket is level and allow for the required fall. Repeat with the other end fascia bracket if the outlet is in the middle of the gutter.
Tie a string line from the outlet to the end fascia bracket, as a guide for installing the remaining fascia brackets. Work outwards from the outlet, remembering that the brackets should be placed no more than 1m apart. survey fasia sheet download
