Basement waterproofing is the work of keeping groundwater and moisture out of a basement, or managing it when it gets in. Interior systems, such as French drains and sump pumps, collect water that reaches the foundation and move it out of the house. Wall repairs, parging and sealing help limit moisture coming through the masonry. Exterior methods address water from the outside of the foundation. The right approach depends on how the water is getting in.

Cost depends on the size of the basement, the method and how much water you are dealing with. Waterproofing costs $5 to $10 per square foot. Interior drainage is usually priced along the perimeter instead. As one example, a 1,000-square-foot basement with about 130 linear feet of perimeter typically costs $4,500 to $7,500 for an interior French drain and sump pump system. At BJK, projects start at $450, and we provide a project-specific price after a free on-site estimate.

It depends on where the drain goes. An interior basement French drain can go from $40 to $85 per linear foot, or $4,000 to $17,000 installed. Adding a sump pump to a French drain costs about $600 to $2,500. Shallow exterior yard drains cost less, typically $10 to $35 per linear foot.

For most homes with water problems, yes. Water in the basement damages walls, floors and anything stored there, and it wears away foundation mortar over time. Waterproofing protects that space, makes it usable, and is an important step before finishing a basement. It also helps when selling, since water problems are a common concern for buyers. The value depends on choosing the right system for the source of the water.

Basement waterproofing contractors, foundation repair companies and drainage contractors all install French drains. Interior basement French drains involve cutting the concrete floor and connecting to a sump system, so they are best handled by a basement waterproofing company. BJK provides interior French drain installation for homeowners in Havertown, Wynnewood, Ardmore and nearby communities. If you are searching for "French drain installation near me," give us a call.

For an interior basement French drain, the concrete floor is cut along the perimeter of the basement. A trench is dug down near the foundation footing, and a perforated pipe is set in gravel to collect water at the base of the walls. The drain is connected to a sump pit and pump that moves the water out of the house. The trench is then covered and the concrete floor is restored.
