Alexandria Exterior Drainage exists because finding a qualified drainage contractor in Northern Virginia is harder than it should be. General landscapers often lack the engineering knowledge that effective drainage work requires. Waterproofing companies push interior solutions when exterior ones would be more appropriate and more durable. And homeowners — often dealing with a recurring wet basement or a chronically flooded yard — don't always know who to trust or what questions to ask.
We are a referral service that connects Alexandria homeowners with licensed, vetted drainage contractors who specialize in exterior water management. We don't do the work ourselves — we make sure the right contractor does it. Every contractor in our network has been evaluated for licensing, insurance, and demonstrated experience working in Alexandria's specific conditions.
Drainage isn't the same everywhere. Alexandria sits on clay-heavy Virginia soil that absorbs water slowly and holds it for extended periods after rain. That soil behavior underlies almost every drainage problem in the city — from yards that pond for days after a storm to basements that collect moisture weeks into a dry spell, fed by hydrostatic pressure from still-saturated ground.
The city's stormwater infrastructure compounds the problem. Much of Alexandria's storm drainage system was built to serve a less dense, less impervious city than the one that exists today. When that system reaches capacity — which it does regularly during heavy rain events — surface water has nowhere to go and accumulates throughout neighborhoods. Homeowners can't fix the municipal system, but they can engineer their own properties to manage water more effectively until it recedes.
Older neighborhoods add another layer of complexity. Alexandria has a substantial stock of historic homes whose original grading, foundation construction, and drainage provisions were never designed to modern standards. Basement moisture intrusion is common in Old Town and surrounding historic districts — not because the homes are poorly maintained, but because they were built in an era that approached water management very differently.
When you contact Alexandria Exterior Drainage, we gather information about your property and your drainage problem, then connect you with a licensed contractor from our network who has relevant experience. That contractor will perform a site assessment, explain what they find, and provide a written estimate. We stay available throughout the process to ensure the referral meets your needs.
There is no cost to use our referral service.
