[quote=Anonymous]We an old colonial with an addition, and the addition was built into a slope but landscaper says the grading is appropriate to channel runoff away from the house. However, we live near a lot of underground streams, and our sump pump runs a few times a day even on sunny days, so I think groundwater is an issue. Even today, with a sunny day, we have some water seeping in through basement wall into the interior french drain. However, for recent rains storms we've had a much bigger leak on a section of the house that does not have interior french drain. Waterproofing companies are saying we need to excavate, seal, and add an exterior french drain to route to sump to keep our basement dry. Is that really our only option? Looking at threads like this, an interior french drain is much cheaper, but will not help the high humidity we have, but should last longer? https://www.dcurbanmom.com/jforum/posts/list/738414.page The numbers for this excavation seem to range from $9k - $30k, depending on the scope of work, using an existing window well drain vs installing a sump. Ugh, wish we lived in a newer house that was built right to begin win.[/quote]
