Costs for exterior waterproofing starts at around $100 per foot and can go up to $200 per foot but may be more under certain circumstances, again depending on the size and difficulty of the job. The depth of the home’s foundation is a major issue in determining cost.
Interior waterproofing isn’t as expensive as waterproofing around the exterior of the home. This option is for homeowners running a tighter budget, or perhaps their home is located too close to neighboring properties, making major excavation work impossible. Interior waterproofing can also be looked at as another layer of home protection for those who also opted for the exterior route.
