The dozydog that I am I have bought a property on an in-fill site. Have lived 2 mins walk on same estate for 35 years. My house was built 2years before this one and have been in pratically all of them watching them being built. Don't shout at me but I didn't have a survey because no-one had ever had any problems. There is a crack running down the wall North East and another South West but not so bad. These are inside and don't show outside. Must be in the brieze blocks only. Didn't think it was subsidence as cracks would start from bottom (wrong!). Have been told by a non-professional to fill with epoxy resin. How will this help? Will it stop further movement? As I say only minor at moment maybe. At what stage should I start really panicking? Should I listen for anything?
