FAQs
Why is my radiator warm at the bottom but cold at the top?
This is usually caused by trapped air. Bleeding the radiator often solves the issue—something we can do quickly during a service.
Can you replace a radiator if it’s beyond repair?
Yes, we offer full radiator replacement if needed and can advise on suitable models and sizes for your home.
What if only one radiator isn’t working?
This could be a valve issue or trapped air. Our engineer will isolate the cause and fix it on the spot where possible.
Is it worth repairing older radiators?
Often yes—but we’ll always give you an honest opinion and suggest replacement if it’s more cost-effective long-term.
