Interior Waterproofing in the DMV
Stop Basement Leaks and Flooding Before They Start
Our proven interior waterproofing systems collect and redirect water before it reaches your basement floor – protecting your home from flooding, mold, and costly water damage.
What Is Interior Waterproofing?
A Proven Basement Waterproofing Solution for Existing Homes

Interior Waterproofing FAQs
Common Questions from DMV Homeowners
Q: Will this stop basement flooding completely?
A: Yes – when properly installed, an interior waterproofing system prevents water from damaging your finished or unfinished basement.
Q: How long does installation take?
A: Most systems are installed in 3–5 days, depending on basement size and scope.
Q: Is interior waterproofing better than exterior waterproofing?
A: Interior systems are ideal for existing homes where excavation isn’t possible. Exterior systems are best for new builds or when the foundation can be accessed from outside.
Q: Will you have to dig up my entire basement?
A: No – our process involves narrow trenching along the walls, minimizing disruption to your space.
Q: Do you offer warranties?
A: Yes – our systems come with lifetime, transferable warranties.

Heidy Lopez2025-06-26 Awesome team of professional workers and very Knowledgeable! We look forward to working with them in future projects. Laura Smalligan2025-06-24 We had a crawl space filled with construction debris we wanted encapsulated and some window wells that were starting to crack. DMV Foundations did a great job from start to finish! Everything was very smooth, the crew was super friendly, and the project was completed on time. Highly recommend! Charles Snyder2025-06-24 Quick and honest evaluation of our home. Not trying to upsell us on anything. Thanks! Melinda Jackson2025-06-11 The guys who worked on our foundation were OUTSTANDING!! They arrived early each day and were very professional. I would recommend DMV Foundation Solutions for any basement or water problems you may have in your home or business!! R. Claude2025-06-11 Russell was amazing and great very knowledgeable couldn’t imagine starting this work on our house without him David Robbins2025-06-10 I had a very good experience with DMV Foundation Solutions. They redid the encapsulation of my crawlspace. I was really pleased that they spent the time during our initial consult to climb down there and take pictures and make sure they proposed the right solution to address my problems. This was in contrast to another contractor who never looked for himself and offered their one-size-fits-all solution. The job lasted a couple days and the crew was punctual, professional and tidy. The project manager was responsive to my phone calls and emails throughout the engagement. I’d absolutely consider them again for future work. luan do2025-06-08 Excellent workmanship. Workers worked in safe, clean and professional manner. Their solution to stop my front patio/stoop from sinking further by using helical piers works. There are two small things that could be improved: removing shoes when entering someone’s home, and arrange for locating sewer and water lines before starting because Miss Utility doesn’t mark these. Michael Jordan2025-06-03 We got a comprehensive assessment from Russell that really pinpointed our waterproofing issues. Mary Fisher2025-05-19 Contacted DMV for some information on a potential home purchase in Alexandria that home inspection revealed had basement water issues. Office Manager Jane chatted with me over the phone and then referred me to her husband, the owner, for a more in depth assessment of the situation. I sent him the inspection report, and he was able to review the issues and give me some info about potential cost and what was involved to to remediate. His response was rapid and professional and greatly assisted us in making a decision as to whether to move forward with the purchase. If their work is anything like their customer service, they are a great find. Love to support small businesses and they went out of their way to help a non-customer. If I ever need their services, would not hesitate to use them for a job.
