Radiator Restoration
Cast Iron Radiator Restoration Services
At Radrestore, we breathe new life into beautiful old cast iron radiators — restoring them to full working order and helping you retain the character, charm, and quality that only traditional radiators can offer.
All restoration work is carried out by our expert team in our UK-based workshop using our carefully refined in-house process. Whether you’re after a fully polished feature piece or a functional classic ready to paint, our two-tiered service structure gives you a clear, simple choice based on your needs and budget.
ALL RADIATORS GO THROUGH OUR RIGOROUS RESTORATION PROCESS
Standard restoration includes removal of old paint, internal clean and flush, test, prime and top coat paint.
Full restoration includes everything in the standard restoration with the addition of every adjoining seal being replaced. For an accurate quotation please email the height, length and a photograph of each radiator to info@radrestore.co.uk
The refurbishment process we use to restore a cast iron radiator is both internal and external, this ensures that when it leaves us to go to you it’s preserved for years to come, meaning we can guarantee our work for 20 years!
OLD FITTINGS
Firstly we remove any old fittings and replace them with modern day equivalents.
Your own radiators that are to be restored by us will be fitted with new 1⁄2 inch BSP bushes with bottom feed and returned, (unless specified by customer) ready to accept modern 1⁄2 inch BSP valve tails. We can supply all the relevant accessories including radiator valves.
LARGE CAST IRON RADIATORS
Any cast iron radiator more than 1.2 meters in length has an additional charge per radiator. They are heavy and need more paint!
SAND BLASTING
The radiators are then moved into the blasting unit, where all the old built up layers of paint, any rust and corrosion are carefully removed from the outside of the radiator.
INTERNAL FLUSHED AND CLEANED
All the old debris built up from the years of being on an untreated central heating system will be cleared and flushed out making the radiator much more efficient.

Advice That Works
We help you choose your radiator with confidence — based on what works, not just what looks good on paper. From BTU calculations and radiator sizing to finish advice and installation planning, our guidance is practical, precise, and shaped by how our radiators actually perform.
We take the time to get it right so your radiator fits your space, your style, and your system.
Work That Lasts
We’re dedicated to building cast iron radiators that stand the test of time. Every unit is restored or built in-house by specialists using traditional methods and modern testing to ensure long-term performance and reliability. That’s why we offer an industry-leading 25-year guarantee on new radiators and full restorations.
Sustainability That Matters
Restoring radiators isn’t just better than replacing — it’s only sustainable when done right. We use recycled iron grit blasting to preserve the casting, avoid acid dipping entirely, and rebuild wherever possible to keep waste low and quality high. It’s how we protect the radiator, reduce environmental impact, and make sure great products stay in service for decades.
