What is crawl space encapsulation?
Crawl space encapsulation is the full transformation of a damp, vented, or dirt-floored crawl space into a clean, dry, sealed environment. The process starts with a heavy-duty reinforced vapor barrier — typically 20-mil — installed across the floor and sealed up the foundation walls, covering the ground completely. We then seal the crawl space vents and gaps to the outside, insulate the foundation walls and rim joists (often with closed-cell spray foam), and, where needed, add a dehumidifier to control humidity. The result is a crawl space that no longer pulls moisture and cold air into your home. Encapsulation solves several problems at once: it eliminates the damp, musty smell that rises into living areas, keeps hardwood and tile floors warm in winter, prevents the structural wood rot and fungi that moisture causes, and lowers summer humidity. Because up to half the air in your home can originate from the crawl space, sealing it has a direct impact on indoor air quality and comfort. For Colorado homes with cold floors, musty odors, or moisture issues, encapsulation is one of the highest-impact upgrades available.
Benefits of crawl space encapsulation
Eliminates moisture
A sealed vapor barrier keeps ground moisture out for good.
Warmer floors
Insulated walls and rim joists stop cold from radiating up.
No musty smell
Sealed crawl space stops damp odors from entering your home.
Prevents wood rot
Controls humidity to protect framing from fungi and rot.
Deters pests
A sealed space is far less inviting to insects and rodents.
Healthier air
Up to half your home's air can come from the crawl space — seal it.
