Sean came to the house on a recce first, Identified the leaks and problems, explained how everything would work and the costs up front. On second visit he got to work he was very diligent. Completed the job in 2.5 days - changed the boiler, instaled the thermostats, also helped in other odd works. I found Sean to be a great tradesman very good at what he does and very helpful. He arrived on time and got the work done quickly. Very happy with the result. He also took the time to explain everything. I would definitely recommend him to any and all my friends.
