We think so! Fitting cast iron is likely a two-person job, as items such as downpipes can be heavy. Aluminium is far lighter and easier to fit, which makes it an excellent choice for residential use where access may be difficult. If you want something straightforward, consider the SnapIt range.

info@tradewarehouse.co.ukWhy Choose Aluminium Guttering?
Aluminium guttering is a smart investment for any homeowner. It provides a sleek look to your home's exterior and offers many benefits compared with other systems, such as uPVC.
Firstly, aluminium guttering is incredibly durable. It can withstand extreme weather conditions, such as heavy rain, snow and hail. Unlike other materials, such as plastic, it is not prone to cracking or breaking. This means your guttering will last many years without needing repairs or replacements.
Secondly, this system is lightweight, making it easy to install. This is a significant advantage over cast iron, which can be heavy to work with and challenging to install.
Another benefit of aluminium guttering is that it's low-maintenance and is not susceptible to rot or decay. This means you don't need to spend time and money sanding, staining, or painting your guttering. Clean it periodically with a hose or pressure washer, and it will look great.
Aluminium rainwater systems are also highly resistant to corrosion. This is especially important if you live in a coastal area like Devon or Cornwall, where saltwater and other environmental factors can cause metal to rust and deteriorate quickly.
It's also a cost-effective option. While it may be slightly more expensive than other plastic materials, it offers superior quality and longevity. This means that you will save money in the long run, as you won't need to replace your guttering system as frequently. The system is also fully recyclable!
