i have a porch which is 10ft by 5ft which seems to wooden clad i hate it and would love to get rid of it but anyway was wondering about getting it pebble dashed so it at least looks like the house abit more!! i would need two walls done, my question is would this be expensive and would it be waterproof and what matience would it need?? it has started to leak and dont exactly know if it is the roof or the wall!!! The roof has jeaked before so needs replaced. I is an ex housing exec house and everyone has the same problems just dont know what to do if a got a brick on built will it be very expensive.
