Xhevi installed a new combi-boiler and underfloor heating in our home. He worked with the builders on a tight timeframe and even came into work on Sundays to get he job done on time. Once his installation was complete, we found out that first the thermostat supplied by the manufacturer was the wrong model and then the replacement turned out to be faulty. To rectify this, Xhevi made several trips to ensure that the correct thermostat was installed and persisted to get the job done! He is very friendly and approachable!
