Lindab Downpipe FAQs
1. What size Lindab downpipe is best for me?
Most homes end up using 87mm Lindab downpipes, especially with 125mm gutters. They handle water flow well without looking oversized. If you have a much smaller roof, you can usually get away with 75mm, while larger or exposed roofs may need 100mm or even 120mm. You can always call or email us: info@tradewarehouse.co.uk and we will assist straight away.
2. Are Lindab downpipes compatible with other gutter brands?
Short answer: well, not really. Lindab downpipes are actually designed as part of a complete system, so mixing with other manufacturers can cause fitting issues or leaks.
If you’re extending an existing Lindab setup, you’re fine. If not, it’s worth switching fully rather than trying to adapt. We also sell Zambelli Galvanised Downpipes on a next day delivery.
3. What’s the difference between 75mm and 87mm Lindab downpipes?
Flow rate and appearance.
75mm suits smaller roofs, extenext-daynsions, sheds
87mm is the most common choice for houses. The 87mm option just gives a bit more breathing room during heavy rain - and it looks more balanced on most façades.
4. Can Lindab downpipes be used in coastal or exposed areas?
Yes — this is one of their strong points. The steel coating offers high corrosion resistance and isn’t affected by salty air or chlorine-heavy environments. That’s why they’re often chosen for coastal homes where aluminium or cheaper steel struggles.
5. Do Lindab downpipes fade or discolour over time?
The standard coated colours are UV stable, so they won’t fade like plastic. Over time, the surface weathers naturally to a darker grey metallic tone, which many people actually prefer. It’s a gradual, even change — not patchy or flaky. You can also paint Lindab gutters.
6. Are Lindab downpipes hard to install?
Not particularly. They’re designed for straightforward installation and can be joined using either an RSK joint or a traditional roll-joint method. Once installed, there’s very little movement, which helps prevent future issues.
7. Why are Lindab downpipes more expensive than plastic?
They’re steel, for a start — thicker, stronger, and far longer-lasting. But compared to aluminium or cast iron, Lindab is often more cost-effective, especially when you factor in lifespan, maintenance, and replacement costs. Plastic might be cheaper upfront, but it rarely wins long-term.
8. How long do Lindab downpipes last?
In real-world conditions, 70+ years isn’t unusual. They also come with a 15-year guarantee, which says a lot. Once installed properly, they’re very much a fit-and-forget system.
9. Are all Lindab downpipe sizes kept in stock?
Common sizes and colours usually arrive within 3–5 working days. Less common options are supplied direct from Sweden. That can take a bit longer, but it means you still get the exact size and finish you need — no compromises.
10. Can I replace just the downpipes and keep my existing Lindab gutters?
Yes, as long as your existing system is Lindab and you match the sizes correctly. This is fairly common when upgrading flow capacity or refreshing the look without replacing the whole system.
