The old sump pump in this house was inadequate. It didn't pump enough water out of the home to keep it dry, and its lack of a lid meant that water could just evaporate back into the basment and make it more humid. In its place, we installed a TripleSafe sump pump system. The TripleSafe, in addition to having an airtight lid, features three different pumps for maximum protection against flooding. The homeowners can rest easy knowing that their basement will not flood, even in heavy rain!

We have discovered mold in our basement - want assistance finding the cause. It does not appear to be black mold and it also seemed to be mixed in with what is referred to as "eflouresseance" on the concrete floor. We also have a bilco door set up for our basement - which leaks in very heavy rains. We would like an assessment of why its leaking and what corrective measures can be taken to eliminate the leaks.
