Basement Wall Sealing in the DMV

Stop Leaks, Block Moisture, and Protect Your Foundation

We seal basement walls using professional-grade materials that keep water out, reduce humidity, and protect your home from long-term damage.

Why Wall Sealing Matters

A Critical Layer of Moisture Protection for Any Basement

Moisture intrusion can lead to mold, odors, wall damage, and even structural deterioration. Sealing your basement walls helps stop this before it starts, especially in older homes or homes with porous concrete.

Wall Sealing FAQs

What DMV Homeowners Ask Most Often

Q: Is wall sealing a permanent solution?

A: Wall sealing is a critical part of moisture protection but may need to be paired with drainage or sump pump systems for full effectiveness.

Q: Can you seal walls from the inside or outside?

A: Yes. We offer both interior and exterior wall sealing, depending on access, budget, and moisture severity.

Q: How long does wall sealing last?

A: Most of our sealants last 10+ years with proper prep and conditions.

Q: Will this stop leaks completely?

A: In many cases, yes. If water is entering through cracks or porous walls, sealing can block the path.

Q: Can I paint over sealed walls?

A: Yes. After the sealant has fully cured, you can apply compatible paints or finishes.

  I cannot say enough great things about Richard, Nicholas and William - the amazing father and son team that came out today to do some waterproofing work in our basement today. They went above and beyond replacing our sump pump. They rearranged piping to make the space way more functional and usuble compared to the original piping. They were so friendly, answered all my questions and left the space cleaner than they found it. 10/10.

  We had water coming into the basement after recent rains and DMV diagnosed the problem and fixed it for a fair and reasonable price.  Very happy with the work they did and the price we paid.  Definitely recommend!

  DMV Solutions really helped us out by encapsulating our crawl space beneath our sunroom.  The workers were on time and cleaned up very well after the work was done.  We are very pleased with the job.

  After struggling with a poor work done on our crawl space by a national company and no help to remedy even though we supposedly have a life warranty.  We made it a priority to work with a local business.  DMV was wonderful to work with, did't pressure us, explained their recommendation and answered questions in a super timely manner.  Their quote was reasonable and best of all they didn't try to upsell us.

  I am a huge fan of DMV Foundation Solutions.

We recently moved into a new home with a list of items that needed attention. Then, after a heavy rain, we discovered another issue: water was flowing into a basement storage area.

I called four or five foundation companies looking for consultations and quotes, and DMV Foundation Solutions immediately stood out. They were easy to schedule, responded quickly, and were extremely thorough in evaluating our home. They looked carefully at both the inside and outside of the property, reviewed the full report from our home inspector, and helped us think through how to prioritize the different repairs. The entire process felt collaborative and solutions-oriented.

Their pricing was also the best we received, and they offered very supportive financing options. At that point, we were already excited to work with them.

Then we met Richard, Nicholas, and William—the crew that completed the work—and they took the experience to another level.

We were incredibly impressed by the quality of their work, their communication, and just how enjoyable they were to work with. This is easily the best team we have worked with on any repair or improvement to our home. They know what they are doing, take pride in their work, and consistently prioritize service, support, and finding the right solution. And they are fun and radiate the most positive orientation. I feel fortunate to have worked with this team and would explicitly request them by name in the future.

We would happily work with DMV Foundation Solutions again, and I have absolutely no hesitation recommending them.

If you have foundation, basement, crawl space, waterproofing, or related repair needs, I strongly recommend giving this team a call and having the conversation. From the initial evaluation through the completed work, they showed up at every phase of our engagement.

  Man... the job was projected 2+ days. They finished in one. I was also credited on a first job  towards an overall improvement.  They showed up on time, neat, and left the premises as clean as when they came. Big thanks to Richard, William and Nicholas for the hard work from DMV foundations.
