Crawl Space Encapsulation

Crawl Space Waterproofing – Protect Your Health from the Ground Up

Your crawl space directly impacts your home’s air quality and structural safety. When left unsealed, it can trap moisture, become a breeding ground for mold and pests, and allow harmful gases like radon to enter your home. Excess humidity and poor airflow can also lead to wood rot, foundation damage, and unhealthy living conditions.

Crawl Space Problems We Solve

Water seepage

Water seepage and standing moisture can cause wood rot, foundation cracks, and mold growth. Our drainage systems stop water before it causes permanent damage.

Humidity buildup

Poor ventilation allows humidity to rise and accumulate under your home. High humidity levels encourage mold and mildew growth, which affects air quality and structural integrity.

Mold and mildew

Mold thrives in dark, damp environments — and an unsealed crawl space is the perfect breeding ground. Encapsulation eliminates moisture, preventing mold from spreading into your home.

Radon gas

Radon is a dangerous gas that seeps into homes through the ground. Our sealed encapsulation systems help block radon entry, protecting your family’s health.

Our Crawl Space Encapsulation System Includes

Custom drainage systems

We install specialized drainage solutions to redirect water away from your crawl space and prevent moisture buildup.

Vapor barriers

High-quality vapor barriers block moisture and create a sealed, clean environment under your home.

Dehumidifiers

Our dehumidification systems keep humidity levels low and improve indoor air quality.

Radon-resistant seals

We can install radon-resistant seals to minimize gas intrusion and safeguard your family’s health.

Don’t let your crawl space affect your family’s health. Let us create a clean, dry, and safe environment for your home.

Problem: Crawl Space issues

Crawl spaces are notoriously difficult to waterproof and often become the most humid part of a home. The stagnant air allows mold, radon gas, and moisture to build up quickly — all of which threaten your home’s structure and indoor air quality. Installing a professionally sealed vapor barrier system will guide water toward a sump pit, similar to a French drain system, preventing water seepage and moisture accumulation. Once sealed by our trained crew, the humidity that once entered your crawl space will stay behind the barrier — protecting your home from mold growth, wood rot, and radon infiltration.

Waterproofing your Crawl Space

Crawl Space Waterproofing & Encapsulation

A complete crawl space waterproofing system is essential to control water intrusion and protect your home’s foundation. In some cases, installing a French drain system and sump pump may be possible if there is enough clearance for proper equipment. However, in many crawl spaces under 5 feet tall, encapsulation is the most effective solution.

This method doesn’t just stop water seepage — it also tackles mold growth, air quality issues, and potential radon gas infiltration. After moisture is controlled, our team can evaluate air circulation and recommend additional steps to ensure a clean, healthy, and stable crawl space.

Concrete Floor finish

In some situations, a concrete floor can be a highly effective solution instead of full encapsulation. After sealing the crawl space, we can complete the project with a robust waterproofing system, mold remediation, and air circulation upgrades. This approach ensures a cleaner environment, improves indoor air quality, and minimizes future moisture-related issues.

Crawl Space Encapsulation

Crawl space encapsulation is a modern solution that protects both the walls and floor from moisture intrusion. This process uses heavy-duty insulation and polyethylene vapor barriers, sealed in place for a durable, airtight, and waterproof environment. A properly encapsulated crawl space improves energy efficiency, protects your home’s foundation, and creates a healthier indoor atmosphere.
