Hi everyone!
I'd like some ideas on how to capture the rainwater running off our balcony. The rainwater currently runs down all three sides, has stained the render and we have had some settling of the house as a result.
Do you think there is enough overhang from the balcony tiles to install gutters on all 3 sides? If there isn't enough overhang on all three sides at the tile-level, do you think a possible solution could be to install gutters on the ceiling of the verandah (underneath the balcony)?
We have a stormwater pit close-by (<3m away) so there isn't an issue with diverting the rainwater once it has been captured but we would really value this community's insights on how to capture the stormwater from the balcony in a cost-effective manner, without having to re-do the entire balcony and install a drain in the middle of it.
Thank you! 
Welcome to the Bunnings Workshop community @emdsd1. It's wonderful to have you join us, and many thanks for your question about installing guttering.
It sounds like you're on the right track with considering guttering around the balcony. Installing gutters along the perimeter of your balcony could indeed help capture the rainwater run-off and direct it to the stormwater pit nearby, which would not only prevent further staining of the render but also help avoid water-related settling issues around your home.
Your balcony possibly has enough overhang, and custom guttering can be mounted directly under the edge of the tiles. This would allow the gutters to catch water as it flows off the surface. You'll want to ensure that the gutters are sloped properly to guide water toward your downpipe and stormwater system. For this, a licensed installer can help make sure it's fitted securely to handle the load and prevent any leakage behind the gutter, which could cause more staining or damage.
If the overhang isn't sufficient, another option is to install a rainwater gutter system on the ceiling of the verandah underneath the balcony. This would act as a secondary solution to catch water that drips down from the edges. However, this method wouldn't reduce the staining, and it may not be as effective at diverting all of the rainwater, especially during heavy downpours. Additionally, you'd want to make sure that any water caught underneath still drains toward your stormwater system.
Either way, I’d recommend discussing your options with a professional, especially since stormwater management is key to preventing long-term structural issues.
Please let me know if you have any questions.
