Is Your Crawl Space Causing Problems?

Warning Signs
You Shouldn’t Ignore

Most homeowners never see their crawl space, but when it’s unsealed, it can quietly cause serious damage. In Arlington, Alexandria, Fairfax, and nearby DMV communities, older vented crawl spaces, humidity, and drainage problems can lead to moisture, mold, wood damage, and poor indoor air quality.

Here are some signs it’s time to schedule a crawl space inspection.

Musty Odors in Living Areas

Smells rise from unsealed crawl spaces through your HVAC system.

High Indoor Humidity

Excess moisture often starts in the crawl space or the ground below your home.

Mold or Mildew Growth

Mold and mildew are signs of trapped moisture, poor airflow, or an unprotected crawl space.

Cold Floors in Winter

Poor insulation and damp air can affect comfort in the rooms above.

Sagging Floors or Rusted Ducts

Moisture can weaken supports, damage wood framing, and corrode HVAC lines.

Additional Usable Storage

A sealed, clean crawl space can become a functional area for safe, dry storage.

Proven Crawl Space Repair Systems

Seal, Insulate & Protect Your Home from the Ground Up

Our crawl space repair systems are tailored to your home, not a one-size-fits-all approach. We assess your crawl space structure, drainage, moisture levels, and airflow to design a solution that protects your foundation and improves indoor comfort.

For homes in Arlington, Alexandria, Fairfax, Bethesda, and throughout Northern Virginia and the DMV region, that often means addressing more than one issue at a time: moisture, insulation, drainage, access, humidity, and long-term protection.

Crawl Space Repair FAQs

What DMV Homeowners Ask Most Often

A: Crawl space encapsulation is the process of sealing the crawl space with a heavy-duty vapor barrier, insulation, sealed vents or access points, and, when needed, a dehumidifier. For Arlington and DMV homes, encapsulation helps control moisture, reduce musty odors, and create a cleaner space beneath the home.

A: Most projects are completed in 2 to 4 days, depending on the size and condition of the space.

A: If your crawl space has standing water, musty odors, mold concerns, damp insulation, cold floors, or high humidity, repair or encapsulation may be necessary. Many older homes in Arlington, Alexandria, Fairfax, and the greater DMV region have crawl spaces that need better moisture protection.

A: Absolutely, encapsulation reduces energy loss and helps regulate temperatures.

A: Yes. Our encapsulation systems include long-term, transferable warranties.

A: Yes. We offer affordable payment options, including 0% interest plans.

Many homes in Arlington, Alexandria, Fairfax, and the surrounding DMV region were built with crawl spaces that were never designed for today’s moisture-control standards. Older vented crawl spaces can allow humid outdoor air to enter, while poor grading, short downspouts, and exposed soil can add even more moisture beneath the home.

Over time, that moisture can lead to musty odors, mold concerns, insulation damage, wood rot, pest activity, and sagging floors. DMV Foundation Solutions inspects the full crawl space environment so we can recommend the right mix of encapsulation, waterproofing, drainage, insulation, and structural repair.

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.
