We are facing the same issue (Montreal, pre-WW2 era condo building). I think the key is to: 1 - Gather some condo owners who are serious about the issue and want to help so that board doesn't get into a perpetual persuation war with the owners. 2 - Be transparent with costs and contracts. Yeah I get it that in construction there is a huge variance on the same job (say $5,000 and $30,000 for the same job and laymen can't tell the difference and in fact the $5,000 one might be better in quality). 3 - Hire a good administration company who is quick to response. his is optional if someone on the board can do the admin job but since everyone is working it's difficult to find such guy.
