Why Manassas Homes Need Engineering, Not Quick Fixes
Prince William's Clay Soil & Aging Drainage Systems
Prince William County sits on expansive clay soil that swells when wet and contracts when dry — putting constant pressure on foundation walls year after year. Many homes in Manassas, Gainesville, and Haymarket were built in the 1970s–1990s with drainage systems that are now aging or undersized.
Combined with Northern Virginia's seasonal rainfall, basement water intrusion is one of the most common problems we see here. Our Manassas branch at 10748 Sudley Manor Dr has been inspecting and waterproofing Northern Virginia foundations since 2005.

The Engineering Difference
Why an Engineer-Founded Company Matters for Your Manassas 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
Manassas Homeowners Ask Us
Why do Manassas homes have basement water problems?
Prince William County has expansive clay soil that swells when wet and contracts during dry periods — putting constant pressure on foundation walls. Many homes in Manassas, Gainesville, and Haymarket were built in the 1970s–1990s with drainage systems that are now aging or undersized. Combined with Northern Virginia's seasonal rainfall, basement water intrusion is one of the most common problems we see here.
How much does basement waterproofing cost in Manassas, VA?
Most residential projects in the Manassas and Prince William 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 Manassas 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 Prince William County.
Do I need a permit for waterproofing in Manassas, VA?
Permit requirements in Virginia vary by city and county. We will advise you on the specific requirements for your Manassas address during the free inspection. We handle all permit applications as part of the project.

Yes. From our Manassas branch at 10748 Sudley Manor Dr, we serve Manassas, Manassas Park, Gainesville, Haymarket, Bristow, Woodbridge, Dale City, Dumfries, and all surrounding Prince William County communities.
Do you use subcontractors in Manassas?
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 Manassas?
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 Manassas?
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.
