Encapsulating Your Crawl Space In Texas
The root of most crawl space problems is moisture seeping into the area beneath your home. In Texas, our clay-rich soils and seasonal rainfall make crawl spaces especially vulnerable. When water enters, it can lead to mold growth, wood rot, and damage to the support posts your home relies on. Excess humidity can also affect the air quality in your home, creating an unhealthy environment for your family.
At Baird Foundation Repair, we help homeowners protect their crawl spaces from moisture damage. Our team installs professional, effective waterproofing and encapsulation solutions designed to keep your foundation dry and your structure secure. With over 55 years of experience, we help you prevent costly repairs, maintain a healthier home, and have peace of mind knowing your foundation is protected year-round.
As a family-owned and operated company, we take pride in offering solutions that last. We proudly serve homeowners in San Antonio, Houston, Austin, and Corpus Christi, where crawl space moisture and shifting soils call for trusted protection for your home.
What Is Crawl Space Encapsulation?
Crawl space encapsulation is a smart solution for homeowners looking to protect their home from moisture, pests, and air quality issues. It’s a system designed to create a fully sealed barrier, controlling humidity, preventing outside air and contaminants from entering, and keeping insects and pests at bay.
Encapsulation covers every inch of your crawl space, no matter the size, using durable, high-quality materials. At Baird Foundation Repair, our goal is simple: separate your home’s interior from the elements outside, creating a dry, healthy, and safe environment that protects both your foundation and your family’s air quality.


The Crawl Space Encapsulation Process
Encapsulating a crawl space means creating a fully enclosed barrier that keeps moisture, pests, and outside elements out. For homes with stem walls or a permanent crawl space covering, we follow a detailed process to ensure your space is completely protected:
Step 1: Level the ground. Before anything else, we make sure the dirt beneath your home is even. Proper grading helps water drain away from the foundation and prevents future moisture problems.
Step 2: Install a sump pump (if needed). In cases where there is excessive groundwater seeping in, a sump pump provides an extra layer of protection, capturing the water and pumping it out to a designated area.
Step 3: Install drainage matting. A drainage mat keeps the liner from resting directly on the ground. Any moisture that collects beneath the liner can drain away properly, reducing the risk of mold and rot.
Step 4: Install the CleanSpace® liner. The polyethylene plastic liner, similar to a pool liner, covers the entire floor and extends up the sides of the crawl space, meeting the floor of your home and the support posts. We fasten, tape and seal the liner to ensure your home is completely sealed off from the earth, creating a secure fit.
Step 5: Add a dehumidifier. A crawl space dehumidifier removes excess moisture from the air, helping prevent mold growth and protecting your home’s structural supports.
At Baird Foundation Repair, we take every step necessary to ensure your crawl space is fully protected. From grading the soil to installing advanced liners and dehumidification systems, our approach gives Texas homeowners peace of mind, knowing their home is safe, healthy, and dry.
Reasons to Encapsulate Your Crawl Space
When your crawl space is safeguarded from moisture and humidity, you help protect your home from their effects. Water damage can cause various secondary problems, many of which can worsen in a short period of time. There are many reasons to undergo an encapsulation service.
Mold and Fungus Grow In Moist Conditions
Mold and other fungi are attracted to dark and damp enclosed areas. These criteria make your crawl space an ideal place for them to grow. Sealing off the area from moisture infiltration makes this environment unsuitable for this growth. It will also protect other areas of your home from mold exposure.
Moisture Causes Structural Damage
Wet conditions can be detrimental to your home’s foundation. The moisture can cause wood to rot and decay, weakening the load-bearing components underneath your house. By waterproofing the area, you’ll create a barrier that protects against these destructive elements. This service will provide additional support to your home and save you money on potential structural or crawl space repair costs.
Contaminants Lower Indoor Air Quality
Even though your crawl space is located beneath your home, it can affect your indoor air quality. When mold and mildew grow in this area, the pollutants can release harmful spores into the air. This bacteria circulates throughout your home, which can lower your indoor air quality. Keeping the area dry and well-ventilated will allow your home to remain comfortable and healthy.
Benefits of Crawl Space Encapsulation
Encapsulating your crawl space isn’t just about protecting your foundation, it’s about improving your entire home. A properly sealed and waterproofed crawl space can provide a wide range of benefits, including:
Increased property value – A dry, stable foundation adds long-term value to your home.
Reduced risk of pest infestations – Keeping moisture out makes your crawl space less inviting to termites and other pests.
Higher energy efficiency – Encapsulation helps your HVAC system work more efficiently, lowering energy costs.
Improved indoor air quality – Sealing out humidity and mold helps create a healthier environment for your family.
Consistent indoor comfort – Enjoy more stable temperatures and less draft throughout your home.
