GTS REBLOCKING are jaw droppingly good. They must have done this for a while because everything just flowed beautifully. Living in the hills often means a difficult job for trades people.... I had a Sloping block...difficult access...and a rotten driveway...they didnt bat an eyelid. They kept up their cheerful good humor and got on with it. When they finished, they cleaned up the mess . Overall an excellent job with a very reasonal price.
