Our recently bereaved neighbour is very vulnerable and we have offered to help her out. Her gate is sticking, and it needs a drop bolt installed. This will involve drilling down into her driveway. We’ve offered to do the job - and we’ve drawn pictures/diagrams to show we need to drill into her driveway. She wants us to do it, but I’m still not sure she understands? Do we do it, or tell her to ask a professional?
