Waterproofing Services in Dunwoody, GA for Basements and Crawlspaces

The ranches and split-levels built in the 1960s and 70s throughout the Village area and along Chamblee Dunwoody Road were typically built on vented crawlspaces. Those vents were standard practice at the time, but they also let stormwater and humid air flow freely under the house. We put in a drainage system along the crawlspace floor to carry water to a sump pit, cover the ground with a moisture barrier to stop clay vapor from rising, and install a pump that activates on its own when water gathers. For a home of this vintage, this is the most impactful upgrade you can make for indoor air quality.

A crawlspace that stays humid without actually flooding needs to be sealed off from the outside. We close off the vents, wrap the interior in a durable liner designed for long-term contact with soil and masonry, and add a dehumidifier that holds the space under the mold-growth threshold through the most humid stretch of an Atlanta summer. The change is immediate: the musty smell that drifted up through the floors is gone, the air conditioner runs less often, and the whole house feels different.

Homes along Mt. Vernon Road, Tilly Mill Road, and in Georgetown frequently have basements, and many of them are finished as living space. That means flooring, drywall, and furniture are all at risk when moisture pushes through the walls. Our system runs a perimeter drain at the base of the basement walls, drops in a sump pit with a pump sized for the space, and applies a wall membrane that intercepts seepage before it reaches the interior. The result is a basement that stays dry and usable no matter what the storm season brings.

The mature trees and established lots that give this area its character also create drainage headaches. Decades of root growth shifts the original grading, and slopes can carry runoff from a neighbor's property uphill directly toward your foundation. We address it with a mix of gravel trench drains along the flow path, surface catch basins at the collection points, and downspout lines extended past the foundation. Where the grade has settled in the wrong direction, we rework it so water moves away from the house.

The wrong pump will either run constantly and burn out or cycle too fast and wear prematurely. We match the pump to the property by looking at the crawlspace or basement size, the local groundwater level, and the storm volume the lot typically handles. The goal is a unit that can run continuously through a DeKalb County storm that parks overhead for hours without failing.
