A top question for homeowners in New Jersey and eastern Pennsylvania searching for prices of basement waterproofing is, how much are these issues going to cost? It is difficult to give accurate pricing as all basements and crawl spaces are built differently in size. An HVAC system, hot water tank, or staircase could be obstacles that may have to be moved. In a finished basement, the drywall will need to be cut horizontally to access a foundation wall. Exterior waterproofing is a lot more involved and may triple the price. The soil next to the walls must be excavated and placed on wood planks or plastic. Decks or driveways for example would need to be detached or removed. These are all considerations with pricing when giving a final estimate.

Below will give a homeowner a clear range of the expense involved with interior or exterior waterproofing in the tri-state area.
