Alexandria Exterior Drainage connects homeowners with licensed drainage contractors throughout Alexandria, Virginia. We serve all city neighborhoods, with particular experience in areas where drainage challenges are most concentrated — older neighborhoods with aging infrastructure, low-lying areas prone to seasonal flooding, and hillier terrain where runoff management is critical.
Old Town Alexandria is one of the oldest continuously occupied urban areas in Northern Virginia, and its drainage profile reflects that history. Many homes in the neighborhood were constructed in the 19th century or early 20th century, before modern foundation waterproofing or engineered exterior drainage were standard practice. Original lot grading was established long before the surrounding street and stormwater infrastructure took its current form, and in many cases those original grades — which once directed water to unpaved alleys and open ground — now direct it toward basement walls and foundations.
The combination of aged foundation materials, clay-heavy soil, and a municipal stormwater system stretched beyond its original design capacity means that basement moisture intrusion is a recurring issue for a significant share of Old Town homeowners. Drainage contractors working in this neighborhood need experience with older construction, historic property restrictions, and the specific soil and topographic conditions along the Potomac waterfront and throughout the historic district.
Rosemont sits on moderately hilly terrain that creates significant surface runoff during rain events. Water moves quickly down sloped lots and accumulates at lower elevations — in yards, against foundations, and in low spots along streets. Properties at the base of the neighborhood's slopes face the combined runoff from multiple uphill lots, often more water than their own drainage systems were designed to handle.
Yard regrading, swale construction, and properly engineered discharge paths are common needs in Rosemont. Without a planned outlet for fast-moving surface water, even well-graded properties can experience erosion and foundation saturation when they sit in the path of uphill runoff. ZIP code 22301.
Kingstowne's residential areas sit in and around naturally lower-lying terrain in the southern part of Alexandria. The neighborhood's position means it receives both direct rainfall and surface runoff from surrounding higher ground. Seasonal ponding — water that stands in yards and low areas for extended periods after rain — is a documented pattern in parts of Kingstowne, particularly where impervious surfaces like driveways, roads, and rooftops concentrate and accelerate water movement onto vegetated areas that can't absorb it quickly enough.
Rose Hill faces a related challenge: dense residential development with high impervious surface coverage means rainfall that would once have percolated into open ground now runs off almost immediately. Catchment basins, French drain networks, and downspout management systems are frequently the right solution in these areas, providing controlled collection and discharge rather than allowing water to find its own path across neighboring properties and toward foundations. ZIP codes 22310 and 22306.
We also serve homeowners throughout the remaining Alexandria ZIP codes, including 22302 and 22309, which encompass the Landmark, Seminary, and Hollin Hills areas. These neighborhoods include a mix of mid-century and newer construction on terrain that ranges from gently rolling to moderately sloped — conditions that generate their own drainage demands, particularly as older landscaping matures and original drainage grades shift over time.
