Why Ashburn Homes Need Engineering, Not Quick Fixes
Loudoun County's Clay Soil Pushes Hard on Old Foundations
Ashburn and Loudoun County sit on dense clay soil that expands when wet and contracts when dry — putting constant pressure on foundation walls year after year. Combined with Northern Virginia’s 40+ inches of annual rainfall and older concrete block foundations common in neighborhoods like Sterling Park and older Leesburg, basement water intrusion is one of the most costly problems we see here.
Our Ashburn branch and warehouse is right here at 44121 Leesburg Pike, Unit 170. We've been inspecting and waterproofing Loudoun County foundations since 2005 — engineer-founded, with in-house crews only, no subcontractors ever.

The Engineering Difference
Why an Engineer-Founded Company Matters for Your Ashburn Home
Our founders started their careers as waterproofing and foundation inspectors at ECS Mid-Atlantic before founding DMV Waterproofing in 2005. That field-inspector background means we diagnose the underlying cause — soil type, water table, foundation construction, drainage failure — before specifying any solution.
Most waterproofing companies sell a product. We engineer a solution.

Frequently Asked Questions
Ashburn Homeowners Ask Us
Why do Ashburn homes have basement water problems?
Loudoun County has dense clay soil that expands when wet and contracts during dry periods — putting constant pressure on foundation walls. Many neighborhoods like Sterling Park and older Leesburg have concrete block foundations built in the 1960s and 70s that are especially vulnerable to seepage. Combined with Northern Virginia’s 40+ inches of annual rainfall, basement water intrusion is one of the most common problems we see here.
How much does basement waterproofing cost in Ashburn, VA?
Most residential projects in the Ashburn and Loudoun County area range from $3,000 to $15,000 depending on the size of the basement, the water source, and the solution required. We provide free on-site estimates with no obligation.
Do you install drain tile systems in Ashburn homes?
Yes. Our FootingShield™ interior drain tile system is installed at footer depth — up to 16 inches deep — to intercept groundwater before it reaches your basement floor. This is the most effective long-term solution for the clay soil conditions common in Loudoun County.
Do I need a permit for waterproofing in Ashburn, VA?
Permit requirements in Virginia vary by county. Exterior waterproofing involving excavation typically requires a permit from Loudoun County DPS. We handle all permit applications and inspections as part of the project — no additional cost or paperwork on your end.
Does DMV Waterproofing serve all of Loudoun County?
Yes. From our Ashburn branch at 44121 Leesburg Pike, Unit 170, we serve Ashburn, Leesburg, Sterling, Brambleton, Broadlands, Purcellville, One Loudoun, and Moorefield Station, plus all surrounding Loudoun County communities. (Reston and Herndon in nearby Fairfax County are also served from Ashburn; Montgomery County and DC are served by our Kensington branch.)
Do you use subcontractors in Ashburn?
Never. Every person who works on your home is a full-time DMV Waterproofing employee. This is non-negotiable — it's how we've operated since 2005.
How long does a waterproofing job take in Ashburn?
Most interior drain tile installations are completed in 1–2 days. Exterior excavation projects typically take 3–5 days. We'll give you a clear timeline at the time of the estimate.
What warranty do you offer on waterproofing work?
We back our waterproofing and foundation work with a written lifetime warranty. Warranty terms vary by solution — our inspector will explain the specific coverage during your free inspection.
Do you offer financing in Ashburn?
Yes. We offer 0% APR financing through Wisetack for projects from $500 to $25,000. Terms range from 3 to 120 months — no penalties, no late fees, no compounding interest. Subject to credit approval.
