There are a number of factors that determine the cost of waterproofing a basement. Below are some of the more significant variables.
The first step in solving a basement seepage problem is to determine what the foundation was constructed of. Foundations in the MD and DC area are most commonly built using poured concrete. Cracks are the most common source of basement seepage in poured concrete foundations. Homes found in this area are often built using concrete block. Older homes are typically built using other types of masonry such as brick and stone. Each type of foundation requires a different method of repair.
In this area, foundations are set minimally four feet in the ground to be below the frost line. Basements that are seven foot and deeper tend to have window wells. The depth of the foundation influences the job because waterproofing deeper foundations require more labor, especially when working from the exterior. Interior waterproofing solutions aren’t influenced as much by the depth.
Sealing a foundation wall crack costs hundreds of dollars. It gets cheaper as we do more. Interior Drain Tile Systems range between $2,000 and $10,000 on average. The price is influenced by the length of the system and added components (sump pumps, wall treatments, etc). Exterior waterproofing solutions vary widely from hundreds to thousands of dollars.

Many municipalities have special requirements that can impact the cost of the job. As an example, some cities require the sump pump discharge pipe to be galvanized steel.
It might sound complicated, but it isn’t when you’ve waterproofed as many basements as we have…we’ve seen it all. And our customers love that we always take a conservative approach.
