Gaps around water pipes, drain lines, electrical conduits, and other utilities can undermine crawl space encapsulation even when the ground liner looks intact. These openings may allow humid air, soil gases, insects, and odors to move through the building envelope. If you are encapsulating a crawl space, sealing these penetrations correctly helps create a more … Read more
A poorly sealed crawl space access door can undermine an otherwise well-planned encapsulation project. Gaps around the frame allow humid outdoor air, pests, drafts, and odors to enter, while a warped or water-damaged door can leave the opening vulnerable to rain and ground moisture. The right fix depends on whether your crawl space is vented, … Read more
A damp crawl space can contribute to musty odors, damaged insulation, wood decay, and recurring moisture problems. Before paying for encapsulation, homeowners need to understand what the project actually includes. A low estimate may cover only a ground liner, while a complete moisture-control project may also require drainage, wall sealing, insulation, and dehumidification. This crawl … Read more
When executing a high-performance crawl space encapsulation, the natural instinct is to roll the white polyethylene sheeting all the way up the concrete block walls and pin it directly flush against the wooden sill plate. While this seems like the neatest way to stop concrete block sweat, it creates a massive structural vulnerability that violates … Read more
How to Fix a Torn Crawl Space Vapor Barrier: Seamless Patching Guide An encapsulated crawl space provides incredible protection against ground moisture, but it is highly vulnerable to physical damage. Whether an HVAC technician accidentally sliced the plastic while servicing ductwork, a plumber dragged a heavy pipe wrench across the floor, or a sharp rock … Read more
How to Fix a Strong Cat Urine Odor After Crawl Space Encapsulation Few issues are as incredibly frustrating as finishing a complete crawl space encapsulation project only to find that your home’s lower level suddenly smells like a pungent cat litter box. If you do not own a cat, this overwhelming ammonia or cat urine … Read more
The Best Vapor Barrier Seaming Tapes for Permanent Encapsulation When homeowners or contractors map out a crawl space encapsulation project, they spend the majority of their time researching the thickness and durability of the plastic vapor barrier itself. While choosing a heavy-duty 12-mil or 20-mil poly sheeting is incredibly important, the ultimate success or failure … Read more
Crawl Space Encapsulation Vent Sealing & Airflow Rules For decades, traditional building codes required home foundations to feature open foundation vents. The theory was that outdoor cross-ventilation would dry out any moisture rising from the dirt floor. However, building science has since proven that open vents do the exact opposite: they pull hot, humid summer … Read more
Choosing the correct plastic thickness for a crawl space encapsulation project dictates whether your moisture barrier lasts for decades or disintegrates within a few seasons. Standard construction-grade clear plastic sheeting from local big-box hardware stores will quickly fail in a subterranean environment. To seal off heavy soil gases, moisture vapors, and radon emissions, you must … Read more
