We noticed a small puddle during a warmer period last week and traced it back to the foundation wall. I removed the drywall and insulation (it was only on top half of wall) and found that the previous owner had patched over a small crack at that spot. They seem to have done a very thorough job and the patch seems fine but it was slightly damp - not wet - to touch so we assume this was the source of the puddle.
Since then we have also cleared the ice around the downspouts and drainpipes and even extended the drain pipes to go further from the house - and we have not seen any water in basement since!!
So - do I need to do anything about this? I am wondering:
- Should I remove and then re-patch the spot that seemed to be the source of the first leak?
- Should I just put a moisture alarm in there and replace the drywall/insulation again?
- Should I just focus on just keeping water and ice away from the house for next year?
As mentioned - there has not been any further leak noticed since we improved the drainage in the area.
