Tailored Downpipe Solutions to Suit Your Property
Every property has different stormwater demands. We assess roof size, rainfall exposure, terrain slope, and council regulations to ensure your downpipe installation meets requirements and performs efficiently. Our team considers:
- The number and location of roof catchment areas
- Optimal positioning for flow and visual appeal
- Council-mandated discharge points (e.g. kerb, stormwater pits)
- The need for water tanks, overflows, or pump systems
For pre-1976 properties where downpipes legally discharged into the ground, we can redesign and upgrade the system to comply with current standards, improving drainage and protecting neighbouring properties.

Downpipe Repairs and Upgrades
We don’t just install new systems – we also inspect, repair, and upgrade your current setup. If your downpipes are:
- Overflowing in storms
- Rusted or dented
- Poorly connected or leaking at joins
- No longer compliant with council standards
…our team can quickly rectify the problem. We realign, reseal, or replace as needed and advise on whether additional downpipes are required to manage water volumes effectively.

Frequently Asked Questions
- Why is proper downpipe installation important?
Correctly installed downpipes direct rainwater away from your property, preventing flooding, erosion, and structural damage.
- Do you install both PVC and metal downpipes?
Yes. We offer PVC for rust-free, quiet performance and Colorbond or zincalume metal options for visual consistency with metal roofs.
- Can you add extra downpipes to improve drainage?
Absolutely. If your current system overflows during storms, adding downpipes can greatly improve water flow and prevent gutter damage.
- Where should downpipes discharge?
In Brisbane, downpipes must discharge to a council-approved point such as a kerb, stormwater pit, or soak well. We ensure full compliance.
- Do you connect downpipes to water tanks?
Yes. We install diverters and leaf filters to ensure clean water collection for rainwater tanks.
- Can you replace just one damaged downpipe?
Definitely. We provide individual repairs or full system upgrades depending on your needs and budget.
- Do downpipes need regular maintenance?
Yes. Periodic checks and cleaning prevent blockages, especially in leaf-heavy areas or older systems.
