What our customers say about us
Called on a Saturday morning and even though he didn’t have any parts for our boiler, Richard came out within the hour to see if he could get it back up and running. Richard did a fab job, the boiler got a mini service and is now running better than before. Would definitely recommend.
Emma
Richard was quick to reply to my enquiry, arranged an appointment to come really quickly and came at the time he said. He had all the parts required to fix my boiler the same day. Really thorough checking everything over and worked cleanly. Would highly recommend and will definitely use him in the future.
Helen
Richard repaired my Vaillant ecotec boiler earlier this year, replacing a worn out dip tube and valves. His preparation for the work was thorough and he explained my options clearly, demonstrating obvious Knowledge of my particular boiler model. Richard was polite and professional in undertaking the work, again explaining what he was doing and why. Whilst at my house he focused on the task and made sure the room he was working in was left in a tidy state.
