We have used Calder Services on 4 occasions in the last 14 months, full new central heating system, toilet overflow, new electric socket and boiler service. The service is excellent from the person answering the phone to the professionals who come out to do the jobs. We know we can phone them for both large and small jobs, it has totally taken away the worry about calling around trying to get a reliable and trustworthy tradesman. They are now our first call without hesitation.
