What Is Crawl Space Encapsulation?
Stop Moisture, Mold, and Air
Quality Issues for Good
Encapsulation is the process of sealing your crawl space with a durable vapor barrier, moisture protection systems, and insulation. In homes throughout Arlington, Alexandria, Fairfax, Bethesda, and the greater DMV region, unsealed crawl spaces are often a hidden source of mold, humidity, musty odors, cold floors, and high energy bills.
Our full encapsulation system creates a controlled environment beneath your home, helping improve indoor air quality, protect your structure, reduce moisture, and increase comfort. This is especially important for older homes in Arlington and Northern Virginia, where vented crawl spaces, exposed soil, and aging moisture barriers can allow humidity to build up under the home.

Crawl Space Encapsulation FAQs
What DMV Homeowners Ask Most Often
Q: Will encapsulation improve my home’s comfort?
Yes, encapsulation helps stabilize indoor temperatures, reduce humidity, and eliminate cold floors.
Q: How long does encapsulation take?
Most crawl space encapsulation projects take three to five days depending on size and existing conditions.
Q: Can this stop mold and mildew?
Encapsulation drastically reduces moisture and humidity, which are the root causes of mold. We can also coordinate mold remediation if needed.
Q: Will I be able to use the space afterward?
Yes. Once encapsulated, your crawl space becomes clean, dry, and usable for safe storage.
Q: Do you offer warranties?
Yes. Our encapsulation systems come with long-term, transferable warranties.
Q: Why is crawl space encapsulation important for homes in the DMV?
Many homes in Arlington, Alexandria, and Fairfax have older, vented crawl spaces that collect moisture from humid summers, heavy rain, and clay soil. Encapsulation seals the space and controls the conditions that lead to mold, wood rot, and poor air quality.
Q: How much does crawl space encapsulation cost?
Cost depends on the size of the crawl space, moisture levels, and whether drainage or dehumidification is needed. We provide a free inspection and written estimate with clear pricing before any work begins.
Q: Do you provide crawl space encapsulation near me in Arlington, Alexandria, or Fairfax?
Yes. We provide crawl space encapsulation throughout Arlington, Alexandria, Fairfax, Bethesda, Herndon, Annandale, Centreville, McLean, and the greater DMV region.

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.Posted on Google

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!Posted on Google

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.Posted on Google

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.Posted on Google

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.Posted on Google

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.Posted on Google
