What Is Crawl Space Waterproofing?
Why Moisture in Your Crawl
Space Is a Problem
Water in your crawl space can cause mold, wood rot, foundation damage, pest activity, and indoor air quality issues. In Arlington, Alexandria, Fairfax, and throughout the DMV region, heavy rain, poor drainage, exposed soil, and high groundwater can lead to standing water or chronic dampness beneath the home.
Crawl space waterproofing protects your home by capturing and draining water before it can do damage. We use sealed systems, sump pump protection, and smart drainage solutions to help keep your crawl space dry year-round.


Standing Water or Mud in the Crawl Space
Damp, Musty Odors in the Home
Mold or Mildew on Wood Supports
Rusted HVAC Ducts or Insulation Damage
Soft or Sagging Floors Above the Crawl Space
Our Proven Waterproofing Process
Engineered to Drain Water Fast and Keep It Out
We design crawl space waterproofing systems based on your home’s layout, drainage patterns, and moisture issues. For homes in Arlington, Alexandria, Fairfax, Bethesda, and nearby Northern Virginia communities, that often means addressing both the water inside the crawl space and the conditions outside the home that allow moisture to collect.
From sump pumps to perimeter drains, our solutions are clean, reliable, and designed for long-term performance.
Channels groundwater to a sump pump for removal before it sits beneath your home.
Automatically removes collected water from the crawl space during rain or rising groundwater conditions.
Enhances water flow beneath vapor barriers and helps direct moisture toward the drainage system.
Detect and alert you to any future leaks.
Installed outside when water intrusion originates from poor grading.
Waterproofing FAQs
What DMV Homeowners Ask Most Often
Q: Do I need waterproofing if I already have a vapor barrier?
If you still have moisture or standing water, yes. Vapor barriers help block humidity, but they don’t remove water already inside.
Q: How long does installation take?
Most crawl space waterproofing systems take 1 to 3 days, depending on the layout and severity of the water problem.
Q: Can I use my crawl space for storage afterward?
Yes! Once it’s dry and sealed, your crawl space can safely be used for clean, dry storage.
Q: Will this fix my musty odors?
Yes. Waterproofing helps eliminate excess moisture: the root cause of most crawl space smells and mold.
Q: Do you offer financing?
We do. Choose from low-interest and 0% options to fit your budget.
Q: Why Arlington & DMV Homes Need Crawl Space Waterproofing
Many homes in Arlington, Alexandria, Fairfax, and the surrounding DMV region deal with crawl space water because of heavy rain, dense soils, older drainage systems, and grading that sends water toward the foundation. Once water reaches the crawl space, it can sit beneath the home and create the right conditions for mold, odors, wood rot, pests, and sagging floors.
Crawl space waterproofing helps manage active water at the source by collecting, redirecting, and removing it before it can damage the home.

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
