Moved in end last summer, fence is 40 yrs old . Between houses itβs concrete boards up to 6ft . Posts are in a very bad way . Fence company due tomorrow. Next door just reminded me that our houses are built on rafts , due to proximity to river . These canβt be damaged in anyway as will cause structural damage to our houses . Anyone faced similar? Iβm thinking theyβll need cutting off ? But how to put back ? Thanks for any ideas !
