A homeowner in Londonderry, New Hampshire, had some water entering their basement. They have noticed this problem since they moved into the home 20+ years ago. The homeowners wanted to repair the problem after doing light cleanup for the past 20 years. They reached out to EFS for a free inspection and our design specialist recommended installing FlexiSpan over the crack in the corner of the basement.
