Interior Waterproofing

Crawl Space Encapsulation

Your crawl space is one of the most overlooked parts of your home, but it can be the source of some of the biggest problems. From mold growth to wood rot, excess moisture and air leaks threaten your home’s foundation, air quality, and comfort. Left untreated, the damage spreads, making your house more costly to maintain.

You don’t have to live with these problems. With a complete crawl space encapsulation, Bramwell-McKay restores control and protects your home for the long run.

Talk to an expert today to see if crawl space encapsulation is the right solution for your home.

How Your Crawl Space Impacts Indoor Air Quality

When your crawl space takes on moisture, the problems don’t stay below your floorboards. Damp ground and leaking foundation walls release mildew and mold that rise into the living areas of your home. Nearly half the air inside the first floor of your house can come directly from the crawl space, carrying with it spores, odors, and humidity that affect your family’s comfort and health.

Instead of masking odors or running dehumidifiers upstairs, the real solution is to address the source. Encapsulation creates a cleaner, drier environment that improves indoor air quality throughout the home.

Professional vs. DIY Crawl Space Encapsulation

Many homeowners try DIY crawl space encapsulation with the hope of saving money. While plastic sheeting and tape can seem like a quick fix, those efforts often fall short. Gaps open, barriers rip, and moisture issues continue unchecked.

Professional encapsulation, on the other hand, addresses the crawl space as part of your home’s entire foundation system.

Our team evaluates drainage, seals foundation walls, installs vapor barriers, and upgrades insulation with materials designed for long-term performance.  We also make sure the work area is cleared of debris, standing water, and damaged materials before sealing anything in.

The difference is more than just materials. It is expertise, precision, and a complete solution that prevents future problems. At Bramwell-McKay, we do the work once, so you don’t have to revisit the same crawl space issues again.

Our Crawl Space Encapsulation Services

We don’t take a one-size-fits-all approach. Every crawl space project is built around your home’s unique needs:

Vapor Barrier Installation

A quality vapor barrier is the backbone of crawl space encapsulation. Our team installs durable liners across the ground and foundation walls, creating a continuous shield that locks out harmful moisture. This protective layer keeps dampness out of your home, while supporting healthier air and stronger floors above.

Debris and Water Removal

Before we begin sealing, the crawl space must be cleared. Our crew removes debris, standing water, and damaged materials to create a clean, stable foundation for encapsulation. Taking this step ensures that no contaminants are trapped under the barrier and that the finished work lasts for decades.

Foundation Wall Sealing

Cracks and gaps in your foundation walls are more than cosmetic. They allow water, humidity, and even pests to slip in. We carefully seal these weak spots, restoring the strength of your crawl space perimeter and protecting the rest of your home from unwanted intrusions.

Air Leak Sealing

Air moves quickly through even the smallest openings. By locating and sealing leaks, we help your home hold a steady temperature and reduce unnecessary drafts. This not only improves comfort but also makes your house more energy efficient in every season.

Dehumidifier Installation

In homes where humidity levels remain high, a dehumidifier can be the difference between a temporary fix and a permanent solution. In addition to encapsulation, we install professional-grade systems that keep moisture in check, supporting healthy indoor air quality year-round.

With Bramwell-McKay, you get more than just a vapor barrier. You receive a complete system designed to keep your crawl space dry, your home strong, and your family comfortable for decades.
