How to Maintain Cast Iron Guttering


When properly maintained, cast iron gutters have a lifespan of over 100 years. However, if maintenance isn’t carried out properly, your gutters will start to rust and corrode. This leaves them looking unattractive and unreliable.

At Cast Iron Superstore, this month’s blog offers advice on how to maintain your cast iron rainwater system. We stock a wide range of products to help you maintain your property’s appearance and prolong the life of your cast iron gutters.


Apply Sealant and Caulk

If you need to repair your cast iron guttering, you need to ensure it is sealed correctly. Sealants and caulk are essential in guttering repairs. They fill in any gaps left from cutting or drilling.

At Cast Iron Superstore, we stock cast iron guttering sealant. To ensure your gutters are properly sealed, make sure you clean the gutter surfaces thoroughly. This guarantees proper adhesion.


Gutter Brackets

Our cast iron gutter brackets are ideal for maintaining all our gutter types. Manufactured to the highest quality, our gutter brackets are available in a galvanised finish and are resistant to the weather.

Available in different sizes, our Britannia cast iron brackets ensure your gutters work to their best ability whilst preserving your property’s timeless appearance.


Painting Your Rainwater System

Painting your cast iron rainwater systems is the best form of protection and maintenance. When it becomes apparent that the surface finish is weakening, paint will add an extra layer of protection against rust and corrosion.

When choosing paint colours, many choose traditional black. However, no matter the colour, ensure your paint is for outdoor use.


Care & Maintenance

With the proper care and maintenance, there is no reason why cast iron gutters can’t last. With the correct prevention and maintenance treatment, you will expand their lifespan.

At Cast Iron Superstore, our products are available in various guttering profiles, including:
