Crawl Space Vapor Barrier Installation

Moisture is your home’s number one enemy. From crawl space flooding and pest infestations to mold growth and structural instability, moisture affects your home’s safety and your family’s health.
Effective crawl space encapsulation with a durable vapor barrier can nip these problems in the bud. When coupled with other solutions, a vapor barrier prevents moisture intrusion, safeguarding your home and family.
If you live in Pittsburgh, Harrisburg, or another city in our service area, you’ll benefit from a complete crawl space encapsulation from Baker’s Waterproofing. As the local authority in crawl space repair, our robust systems shield against moisture, ensuring your home’s overall health and longevity.
What is a Crawl Space Vapor Barrier?

A crawl space vapor barrier is a durable plastic liner that covers the walls and exposed dirt floors of the crawl space area. It is a crucial element in combating excessive crawl space moisture.
Its primary function is to impede the ascent of water vapor into the crawl space, offering comprehensive protection against dampness, mold growth, wood rot, and pest infestation.
Big-box store vapor barriers are often thin and fail to properly protect your crawl space. At Baker’s Waterproofing, we believe you deserve better. When you choose us for your crawl space encapsulation, you benefit from our lasting, multi-layered 20-mil vapor barrier. The barrier protects your crawl space and contributes to the overall health of your home, providing a holistic solution for your entire home.
Signs You Need a Crawl Space Vapor Barrier
Recognizing the need for a crawl space vapor barrier prevents dangerous and costly damage. Stay alert to these signs:

- Higher than-average energy bills
- Increased humidity within your home
- Wood rot and deteriorating structures
- Standing water or wet insulation
These signs indicate the presence of excessive crawl space moisture, drainage problems, and other damage. They’ll only get worse over time, so vigilance is essential to maintaining a safe and healthy home. Don’t hesitate to contact Baker’s Waterproofing at the first sign of a problem.
Is a Crawl Space Vapor Barrier Necessary?

Yes, installing a vapor barrier is necessary when signs of a damp or wet crawl space are present. Without this protective layer, moisture can freely infiltrate, resulting in damage and escalating repair costs over time.
Taking swift action is important, but we do not recommend DIY installations. Unlike thin liners from big-box stores that may lack sufficient protection, professionals ensure robust defense against potential moisture damage in your crawl space.
Entrusting crawl space encapsulation to experts like Baker’s Waterproofing guarantees effective, long-lasting solutions.
What Are the Benefits of a Crawl Space Vapor Barrier?
Preventing moisture at its source with a durable vapor barrier offers numerous advantages, such as:
- Enhanced Air Quality: Vapor barriers inhibit moisture, minimize mold and mildew growth, and improve your home’s air quality.
- Reinforced Structural Stability: Maintaining a dry crawl space safeguards your home’s structural integrity, offering protection from the ground up.
- Increased Energy Efficiency: A dry crawl space translates to an insulated one, resulting in improved energy efficiency and reduced utility bills.
- Pest Deterrence: Damp crawl spaces attract pests like termites. Employing a vapor barrier and other moisture management solutions creates an environment less appealing to pests, making it challenging for them to infiltrate your home.
Our exclusive CrawlSeal™ vapor barrier liner is puncture-resistant and contains antimicrobial properties. When combined with our encapsulation process, it ensures your crawl space remains consistently clean, dry, and well-ventilated for many years.
