Ok, drain tile and honestly ALOT. Buuut if you got people that could help you dig for cheap not that bad.Water comes up from almost every side of the house in the basement, so would be a drain around the perimeter that dumps into a sump pump and kicks it out. Would be maybe 150ft of drain for the perimeter
hell, he could jus build a treehouse for a helluva lot cheaper
ppp
Yet... I was thinking more like 5-10k
