Start with the source of the water

The right protection depends on whether the concern is sewer backup, groundwater or pump reliability. We will explain the difference before recommending work.

Keep the sump pit and discharge route working

A sump pit collects groundwater so the pump can discharge it outside. Sediment and debris can obstruct the equipment. Ask us to assess the pit, pump and discharge route, or discuss electronic wireless flood protection for your home.
