“Hi Ashley Just to let you know we had a call from a customer who had recently bought a property and every time they lit the stove it filled the house with smoke I went to look at the job and the problem was clear a slightly short flue that had the extra problem of a tree growing over the top of the flue outlet the flue had a standard cowl fitted this was making the pressure zone even worse the big problem was that the tree had a protection order on it so it couldn’t be cut down !!! We fitted a flue cube and the problem was cured instantly Kind regards”
