    You are not the most inexpensive company to work with however your guarantees and sales representative made you our first choice. Further, Your crew had the utmost patience with us when medical situations for a family member caused us to postpone our installation date 4 times! Your sales rep, Rick Raucci and your office scheduler were wonderful.

    Old sump pumps without covers like this one allow water vapor to evaporate back into the basement, creating more basement problems like mold. With the airtight lid on the SuperSump that we installed in its place, we were able to keep water in the sump pump system, and also keep out any dirt and debris that could clog a sump pump.

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
