Imagine living in house with mould and dump stains on your walls, appearing from constant rain. Not very pleasant, is it. What would you do to get rid of it? Buy expensive cleaning sprays to remove mould or repaint your walls again. Well it would help for while, but it would cost you a fortune and most of your time. Why not investigate the fundamental problem. Where is the major leak coming from? Well most of the cases are blocked gutters. Remember, if your gutters are blocked, the water always finds a way. Clean gutters save you money.
