How much does basement waterproofing cost in the DMV area?

The cost varies depending on the size of the basement, the source of water intrusion, and the solution required. Most residential projects in the DC, Maryland, and Virginia area range from $3,000 to $15,000. We provide free on-site estimates with no obligation.

How long does a basement waterproofing project take?

Most interior waterproofing jobs are completed in 1-2 days. Exterior waterproofing projects, which involve excavation around the foundation, typically take 3-5 days depending on the size of the home. Our team works efficiently to minimize disruption to your home.

Do you offer a warranty on your waterproofing work?

Yes. DMV Waterproofing backs its work with a written warranty. Warranty terms vary by the type of solution installed -- our inspector will explain the coverage in detail during the free estimate.

What makes DMV Waterproofing different from other companies?

DMV Waterproofing was founded by two civil engineers with over 20 years of experience in large-scale construction including tunnels, subways, and high-rise buildings. Unlike competitors who use shallow plastic drain channels, our interior drain tile system is installed at footer depth -- up to 16 inches deep -- intercepting water before it ever reaches your basement floor. We use no subcontractors, and every job is performed by our own trained crews.

Do I need to leave my home during the waterproofing work?

In most cases, you can stay in your home during the project. Our crews work in the basement only, and we take precautions to contain dust and debris. We will let you know in advance if any specific step requires temporary access to other areas.

What are the signs that my basement needs waterproofing?

Common signs include water stains or white chalky deposits (efflorescence) on walls, musty odors, visible mold or mildew, damp or wet floors after rain, and cracks in foundation walls or the floor slab. If you notice any of these, contact us for a free inspection.

Do you serve all areas in DC, Maryland, and Virginia?

Yes. We operate from three branches -- Rockville, MD; Ashburn, VA; and Manassas, VA -- covering the entire DC metropolitan area including Washington DC, Northern Virginia, and suburban Maryland.

Do you offer financing for waterproofing projects?

Yes. DMV Waterproofing offers flexible financing through Wisetack. Projects from $500 to $25,000 qualify, with terms ranging from 3 to 120 months. Rates start at 0% APR for 3-month plans -- no penalties, no late fees, and no compounding interest. Financing is subject to credit approval.

Do I need a permit for basement waterproofing in DC, Maryland, or Virginia?

Permit requirements vary by location. Washington DC requires a permit for most waterproofing work. In Maryland and Virginia, requirements differ by city and county -- some jurisdictions require permits while others do not. DMV Waterproofing will advise you on permit requirements specific to your location during the free estimate.

Should my sump pump have a battery backup?

Yes, we strongly recommend a battery backup sump pump. Power outages most commonly occur during heavy storms -- exactly when your sump pump is working hardest. A battery backup ensures your basement stays protected even when the power goes out. We install battery backup systems as part of our sump pump installations.
