Okay, this is not my situation but I don't want it ever to become mine either, so... How do you "CYA" on foundation excavation. My mentor stopped doing hardscaping (with a $25 mil yr. business) due to a situation where a homeowner blamed them for a crack in the foundation of their home. Now, he states that the damage was pre-existing and the homeowners were out of town and could not be contacted to report it. Well, when it was all said and done, he paid for the repairs in excess of $8000.00 because, as he quotes, "the referral is worth the loss". Personally, I can't pay $8000 for a referral. If something like this happened to me I would probably feel that loss for a couple months. So, how do we, as hardscapers, protect ourselves from being blamed for foundation damages?
