I too have had damage from a leak from the flat above me causing ceiling damage including lights in the ceiling. I am going to have to claim on the block buildings insurance. However, I am having little luck in finding someone relatively local to provide an estimate for the work. If any others who have gone through the process have had estimates and/or work done I’d be interested to know who they used. (The insurance company is not going to send a loss adjuster but will assess the estimate I get). The post code is in WC1. Thanks in advance.
