Crawl Space Encapsulation
Helping Crawl Spaces Stay Dry Since 1987
Crawl spaces throughout Maryland are affected by year-round moisture. Spring storms soak the soil, hot summers push humid air into vented crawl spaces, and winter temperature swings create condensation on wood and masonry.
Rather than letting that hidden space quietly cause trouble, encapsulation turns it into a cleaner part of your home’s overall system. With decades of experience, Allmaster Home Services listens to what you’re seeing upstairs, checks what’s happening below, and then builds a plan that makes sense for your home and budget.
The Hidden Moisture Cycle Beneath Your Home
Most older crawl spaces weren’t built with modern moisture control in mind. Vents were supposed to “let the space breathe,” but in Maryland’s climate, they often do the opposite. Warm air moves in, cools down, and then settles on joists, insulation, and foundation walls.
Over time, this can lead to:
Musty, earthy smells that rise into your home
Mold or mildew on wood, insulation, or masonry
Damp soil and staining on foundation walls
Floors that feel soft, uneven, or bouncy
Rodent or insect activity below the house
Cracks or moisture starting to show up on the basement walls
Encapsulation helps break this cycle by turning the crawl space into a dry and more predictable environment. It also supports better air quality upstairs, since air naturally moves from the crawl space into the living areas.
If any of these signs sound familiar, a free inspection from Allmaster can help you see what’s really going on and whether encapsulation is the right next step.
Key Components of Crawl Space Encapsulation
Encapsulation is more than just rolling out plastic on the floor. Our approach blocks ground vapor, limits outside air, and manages water in a controlled way. The goal is to create a durable, continuous barrier beneath your home that protects everything above it.
A typical crawl space project may include:
Thick Vapor Barrier on Floors & Walls
A heavy-duty liner is installed across the floor and up the walls with tightly sealed seams, so moisture from the soil and masonry can’t easily move into the air.
Result: Lower humidity and a more stable crawl space environment.
Sealed Vents, Rim Joists, & Access Points
Closing and sealing these openings helps keep summer air and winter drafts from constantly moving through the space.
Result: More consistent conditions and less stress on your heating and cooling.
Drain Tile & Sump Pump
When water seeps in during storms or high-water-table periods, interior drain tiles and sump pumps collect and move it away from the foundation.
Result: Less risk of standing water and long-term damage around the footings.
Integrated Water Management
Crawl space drainage can be tied into basement waterproofing or yard drainage, so everything works together.
Result: One coordinated plan instead of juggling several contractors and patchwork fixes.
Documented Inspections
Before any work begins, we’ll take photos and measurements so you can see exactly what’s happening under your home and how the system will address it.
Result: Confidence that the solution targets root causes, not just surface symptoms.
We customize every plan to the home we’re working on. Soil, grading, and foundation layouts can look very different from one property to the next in Pasadena, Glen Burnie, Severna Park, and nearby communities, so the system we design always reflects what we find on-site.

I’m quite happy with the improvement in energy efficiency that was achieved by installing the radiant barrier in my attic last year. Even after installing a new energy efficient heating/AC system the previous year, the AC bill was much lower than it was the year before(barrier) and my heating bill this last, long cold snowy winter was lower than it’s ever been in the thirty years I’ve lived here! Great job guys!
