We have a home built in 1940 and have had water coming in during big storms. It's been more frequent in the past 6 months so we were hoping to get a professional opinion around the best way to tackle the issue
Vicinity of Harrison Ave in Portsmouth
Just finished my basement by myself this winter. Came out great. The basement had been dry for many years, so I though there was no big deal in finishing it and putting breathable carpet as flooring. The other day, the heavy rains caused us to get some water in the basement. I don't want this to happen anymore so I want to see what I can do about it. Please call me.

Vicinity of Broad Street in Portsmouth
Seasonal damp basement, with cracks in the floor. some due to buried, discontinued, oil feeds, some possibly due to hydrostatic pressure. We purchased the house exactly one year ago, and had been told the basement was dry! Foundation is brick over stone, with some weeping this spring at the uphill side of the house. Looking to create a strategy for remediation, and would like to recapture the basement for light utility, (and peace of mind).
