Steel Guttering Frequently Asked Questions
-
How Do I Install the Outlets?
Since our steel gutters are bespoke, the aluminium outlets are supplied separately. You will need to mark the exit point on your guttering and use a hole saw or drill to create the opening before securing the outlet.
-
Are the Joining Straps Really Free?
Yes. For any steel guttering order where multiple lengths are required, we supply the necessary butt straps at no additional cost to ensure a professional, watertight joint.
-
Do I Need to Buy Brackets for the Downpipes?
No, all of our steel downpipes come with fixing brackets included as standard, so you have everything you need to secure them to your building.
