We have our house up for sale. We have redwood siding. It was painted just 3 years ago and I have recaulked anywhere the cracks in the caulking are over 1/16", but do I need to crack those small ones? They just come back each year as the seasons change (We live by the water in a very humid climate), but I don’t want to get dinged by a house inspection. Would water really get in those small cracks and do any damage?
