Humidity Issues

This shrinking or “condensing” of the air volume leads to greater humidity. Everything permeable in your basement will soak up the additional moisture in the air and trigger a foul smell. Dehumidifiers are appliances which mechanically eliminate the unwanted additional humidity from your basement. A good dehumidifier is a need to if you plan on redesigning your basement. Even a basement that does not leak will gain from using a dehumidifier.

Water Leak

If a corner of the basement appears to be a specific issue, once again, look outside at your gutter downspouts. If you see fractures in the walls dripping, some of these can be repaired with hydraulic cement or fracture injection. If water appears to be coming in from an isolated area, setting up a sump pump below floor level can reduce the water level and underground hydrostatic pressure because area. If you are unsure or your issues seem to be widespread, it may be best to call in a building inspector, engineer or other professional to help you identify and resolve your issue. There are a range of services readily available to resolve your leak issues. These include; outside excavating, re-parging your walls, interior or exterior drain systems, interior cove systems, grout or epoxy injection and others.
