Crawl Space Encapsulation
A crawl space is part of your home’s foundation system. When moisture builds up below the floor, it can feed mold, odors, wood damage, and uncomfortable rooms above.
Our CrawlShield™ system seals the crawl space, controls ground vapor, manages drainage, and keeps the air dry with an engineered approach built for DMV humidity.
We fix the moisture source before we cover it.
A pretty liner over a wet crawl space is not a repair. We first identify whether the problem is ground vapor, bulk water, open vents, failing grading, plumbing, or an overloaded sump route.
Then we design the encapsulation around that cause so the space stays dry after the crew leaves.
Ground Vapor
Soil moisture rises constantly and condenses on cold framing, ductwork, and insulation.
Bulk Water
Water entering after storms needs drainage, not just plastic sheeting.
Air Leakage
Open vents and gaps pull humid air into the crawl space all summer.
Conditioned Air
The final system needs predictable humidity control and serviceable equipment.
A CrawlShield™ install is built in layers.
Each step is meant to remove a failure path: water, vapor, air leakage, and humidity.
Inspection and Moisture Mapping
We inspect access points, grading, walls, piers, joists, insulation, and active water paths.
Drainage First
If water is entering, we add the right drain route or sump connection before encapsulation.
Surface Preparation
Debris, damaged insulation, and affected materials are removed so the barrier can seal cleanly.
Barrier Installation
A reinforced vapor barrier is sealed across the floor, walls, columns, and penetrations.
Vent and Air Sealing
Exterior vents, gaps, and service penetrations are sealed to stop humid air cycling.
Humidity Control
A dehumidifier or conditioning strategy is sized for the crawl space volume and moisture load.
What You Should Notice
The right crawl space repair changes the whole house, not just the area under it.
- Less musty odor near first-floor rooms
- More stable indoor humidity
- Cleaner air moving through ducts and floor cavities
- Reduced risk of mold, rot, and pest activity
Why It Matches Our Shield Systems
CrawlShield™ often works with drainage and mold remediation because moisture problems rarely stay in one category.
- Can pair with MoldShield™ when growth is already present
- Can pair with YardShield™ or WallShield™ when surface water is feeding the crawl
- Installed by in-house crews with one repair plan
- Designed for DMV clay soil and humid summers
Make the crawl space dry, sealed, and boring again.
We will inspect the crawl space, explain the moisture source, and recommend the simplest engineered system that actually solves it.
