Interior Waterproofing

Vapor Barrier Installation

Nearly half of the air on your first floor can come directly from your crawl space, which means any dampness, mold, or mildew below can affect the air your family breathes. Left unchecked, ground moisture seeps upward, leading to mold growth, weakened structural elements, and indoor air quality concerns that can affect your family’s health. A professionally installed vapor barrier stops water vapor at the source, protecting your home from the ground up.

Bramwell-McKay provides expert vapor barrier installation designed to seal crawl spaces, protect foundations, and create healthier environments. Our team uses high-quality vapor barrier material, applies proper sealing techniques, and follows local building codes to ensure your system is built to last.

A Properly Installed Vapor Barrier Protects Structural Integrity

Crawl spaces are especially vulnerable to ground moisture and trapped air. Without a barrier in place, water vapor rises through the soil and spreads into the structure, creating a damp space where mold and mildew thrive. Over time, the damage reaches beyond the crawl space, weakening floors, walls, and even your home’s foundation.

A properly installed vapor barrier shields the structural components of your home from this constant exposure. By sealing out moisture vapor and protecting wood, concrete, and other structural elements, the barrier helps preserve your home’s structural integrity. It not only supports healthier air but also extends the life of the foundation and framework, preventing small issues from escalating into costly repairs.

Our Vapor Barrier Services

We offer complete vapor barrier solutions tailored to your home. Each service is designed to address specific needs while protecting your family’s health and the strength of your foundation.

Crawl Space Vapor Barrier Installation

When your crawl space feels damp or musty, a crawl space vapor barrier provides the first line of defense. Our team installs high-quality vapor barrier material that blocks ground moisture before it rises into your home. By carefully sealing the soil, walls, and perimeter, we help protect your foundation and improve indoor air quality.

Vapor Barrier Replacement

Over time, an old barrier may tear, shift, or lose effectiveness, leaving your home vulnerable to moisture problems. We remove damaged material and replace it with a durable moisture barrier that restores full protection. Our replacements are done with proper overlap, sealing, and adherence to local building codes, so you can feel confident your crawl space is once again safeguarded against mold and structural damage.

Additional Moisture Control

Some homes face more persistent challenges, especially in areas with heavy rainfall or high humidity. In those cases, a vapor barrier alone may not be enough. We design comprehensive solutions by pairing your barrier with a dehumidifier or drainage improvements, creating a system that actively manages moisture year-round. This service gives homeowners peace of mind that their crawl space will stay dry no matter the season.

Crawl Space Vapor Barrier Installation Process

Many homeowners are curious about what really goes into sealing a crawl space. To give you a clear picture, here’s how our team handles the process:

Preparation and cleanup
We remove debris, level the soil, and prepare the area for effective installation.
Lining the crawl space
Durable plastic sheeting in various thicknesses is rolled out to cover the ground, walls, and perimeter.
Sealing and overlaps
Sheets are taped, overlapped, and sealed at edges to block water vapor and maintain effectiveness.
Detailing around obstacles
We seal around pipes, walls, and structural elements to create a continuous barrier without gaps.
Final inspection
Every seam and corner is checked to confirm the vapor barrier is fully secure and compliant with local building codes.
Our installation process is designed to provide a clean, dry, and reliable vapor barrier that protects your home for years.

Vapor Barrier Installation Cost

The cost of vapor barrier installation varies depending on the square footage of your crawl space, the type of materials chosen, and the condition of the area before work begins. A small space with little preparation may require less time and expense, while a larger area with debris or existing moisture problems can involve more work and a higher overall cost.

When you work with Bramwell-McKay, we provide upfront estimates that include both materials and labor costs. We explain the options—such as different vapor barrier materials and thicknesses—so you can make an informed decision that fits your budget and long-term goals.
