How long do cast iron gutters last?

Considering replacing your deteriorating cast iron guttering, or maybe you’d like to capture the personality of your period property by replacing the modern UPVC rainwater management system with a character-packed alternative?

Whatever your reasoning for revamping the exterior of your property with cast iron guttering, our decades of experience making material and installation recommendations for metal rainwater systems can help.

Below, we discover when you should replace cast iron gutters and what’s involved in the process.

When should you replace cast iron gutters?

Typically, cast iron gutters can last an impressive 50 years. With the appropriate maintenance, this expected lifespan can be increased to a century. Generally, however, you should seek out a cast iron guttering replacement when yours develops significant leaks that render the rainwater system ineffective or unsafe. This is often anywhere between 50 and 70 years post-installation.

Cast iron guttering is vulnerable to rusting if it is not looked after appropriately, and tiny holes will grow into larger ones if left untreated. While minor leaks can be repaired, more substantial guttering damage will require a permanent solution. In that instance, we recommend either replacing the individual damaged section (a fantastic benefit of cast iron guttering) or opting for a complete system replacement if the guttering has reached the end of its lifespan.

How to replace cast iron gutters?

Once you’ve decided to go ahead and replace your cast iron gutters, you’ll need to find out what’s involved in the process.

First, you should start by removing the unwanted UPVC guttering or scrapping the original cast iron guttering (something that your wallet can benefit from, thanks to cast iron’s scrap value).

After removing the original guttering, you’ll need to source new suitable replacement cast iron guttering and downpipes in a style that complements the character of your property. Luckily, we have plenty of traditional styles to choose from, including half round, deep half round, beaded half round, victorian ogee and moulded ogee.

You’ll also need to check the condition of the cast iron gutter brackets, the method used to attach the gutters, and the traditional cast-eared collars which hold the downpipes in place, to ensure safe and effective rainwater drainage.

If any of these components are cracked or in poor condition, then you’ll need to source new ones.

Replacing cast iron gutter brackets? We can help here with our extensive selection of cast iron guttering fittings and accessories. Once you’ve purchased the right cast iron guttering and brackets for your property, you can begin the installation process. You should install the cast iron guttering according to the product’s specific instructions.
