Garage issue

This is a common issue with 1970s sectional garages. Since you are in the process of buying, you need a clear technical assessment to negotiate the price. ​The detached garage has likely shifted because the internal galvanised bolts have rusted away or the concrete base has subsided. Because these are "bolted" sectional builds, you can absolutely dismantle or repair your half without bringing down the neighbor's side, provided you handle the shared junction correctly. ​The Solution... ​First, check the central line. These garages usually share a internal "twin" post or a bolted seam. A specialist can unbolt your sections and install a new permanent end-wall or support pillars to leave the neighbor's garage fully enclosed and structurally independent. ​Regarding the asbestos roof, these are typically Chrysotile (White Asbestos) cement sheets. You can remove your side, but the sheets often overlap the neighbor's roof at the ridge. A professional must "stitch" the joint, meaning they carefully cut or unbolt the overlap and install a new weathering flashing or a permanent gable end to seal the neighbor's roof safely. ​Repair is possible by replacing the rusted fixings and realigning the slabs, but if the concrete panels are cracked or the frame is warped, demolition and a fresh rebuild is often more cost-effective. ​Kind regards, ​Matt Custom Builds UK Ltd
