Hello everyone, i'm new to this but here goes. I've a three bed semi which had a side extension built which was a carport with an extra bedroom and bathroom above the carport. This was built before i had the property. About 6 years ago through the insurance i had the car port extension underpinned due to subsidence using a mini piles system. This has stabilised the extension but recently i bricked up the front of the extension and maybe in the future plan to convert the car port into a living area. But now it is obvious to see that when the car port was underpinned that the walls weren't jacked up and it is obvious to see that they have dropped by approx 2". The question i've got is how easy is it to jack up the wall and secondly what are the sort of costs for doing this. Thanks for any assistance
