Definitely recommend Kristian to everybody. Our flat has a 15 years old boiler with a twin flue system which has reached its end of the life in this particular cold winter. We asked a lot of engineers to quote and to get this replaced. Everyone is trying to rob us because we are suffering with no heating and also complained about this and that problem and says how difficult the job is without any constructive suggestions. But Kristian came with really good price and proposal and promise to restore it just as it used to be. On the other hand, he is very disciplined, honest and respectful, maybe because of previous experience in the army. Great respect. He finished everything nicely as he promised, replaced the boiler, get the plaster done, get the painting done and even get our warranty registered. We are just enjoying the whole process.
