Crawl Space Encapsulation & Repair Services in Seagraves, TX
We focus on long‑term moisture control, structural protection, and healthier indoor air using materials that meet or exceed Texas codes. Every project starts with a free moisture assessment, then we design the right combination of sealing, drainage, insulation, and humidity control for your home.
Crawl Space Waterproofing
Water and humidity can creep into Seagraves crawl spaces after storms or irrigation, causing mold, wood rot, and odors. We stop it with a sealed Class I vapor retarder, targeted air sealing, and water management. Where needed, we add dimpled drainage matting, a perimeter French drain, and a sump basin with a reliable pump and check valve. Our safety‑first crew uses moisture meters, laser levels, and sump pump test kits to verify performance. The result is a dry, stable crawl space that protects your flooring and improves indoor air quality.

Crawl Space Vapor Barrier Installation
A professional vapor barrier is the foundation of effective encapsulation. We install a 20‑mil reinforced polyethylene liner (ASTM E1745 Class A) with 6–12 inch overlapped seams sealed using butyl and acrylic tapes. The liner runs 6+ inches up foundation walls and is mechanically fastened with termination bar and masonry fasteners. We isolate piers with sealed boots and detail around plumbing/HVAC supports. This tight, clean membrane blocks ground moisture and musty odors while preparing the space for insulation and humidity control.

Crawl Space Dehumidifier Installation
After sealing, we keep relative humidity at 45–55 percent with a crawl‑space rated dehumidifier (70–100 pints/day), sized to your square footage and leakage rate. Units are installed with a condensate pump, dedicated GFCI‑protected circuit when required, and a drain line tied in by a licensed plumber when necessary. We add a hygrometer/data logger for ongoing monitoring. This protects wood framing, suppresses mold growth, and helps lower indoor allergens - especially helpful through humid summer spells and post‑rain events.

Crawl Space Drainage System Installation
If groundwater or roof runoff collects under your home, we install a discreet interior drain system. Using perforated pipe with a fabric sock, a sump basin and pump, and dimpled drainage matting beneath the liner, we capture and discharge water away from the foundation. Discharge piping is routed to code by a Texas‑licensed plumber. We test every system and can add a high‑water alarm or backup pump for extra protection during West Texas downpours.

Crawl Space Insulation Installation
For energy savings and comfort, we insulate foundation walls with rigid foam board (XPS/EPS) adhered with foam‑safe adhesives and seal rim joists with closed‑cell spray foam. This approach outperforms fiberglass batts, reduces air leakage, and helps meet IECC energy goals. We maintain a visible termite inspection gap at the top of wall foam and seal vents/penetrations for a durable, code‑compliant assembly tailored to Seagraves homes.

If you’re comparing providers for Crawl Space Encapsulation Seagraves TX, see what sets us apart below.
Certified Expertise and Code Compliance
Our project managers are trained in building science and energy codes (BPI/RESNET), with ICC familiarity for Texas residential code. We’re active with the Basement Health Association and stay current on ASTM E1745 Class A vapor retarder standards. That means your encapsulation meets the intent of R408.3 for unvented crawl spaces - including sealed Class I vapor retarders and mechanical drying via exhaust, dehumidification, or minimal supply air.
Every job starts with diagnostics: moisture meters, thermo‑hygrometers, and documented photos. We specify materials and details such as 6–12 inch seam overlaps, 6+ inch wall terminations, and termite inspection gaps at foam - so inspectors, appraisers, and buyers can see the quality and compliance.
Safety, Licensing, and Insurance
We treat crawl spaces as potential confined spaces and follow OSHA entry procedures: PPE, ventilation, continuous communication, and clean access. For water and mold, we’re qualified with IICRC WRT/AMRT technicians and hold a TDLR mold remediation company license. Our team is fully insured for your protection and maintains OSHA safety training.
Electrical and plumbing details are handled by licensed pros when required. We install GFCI‑protected receptacles and dedicated circuits for dehumidifiers and pumps through a TDLR‑licensed electrician, and route sump discharge/condensate lines with a TSBPE‑licensed plumber. We finish with HEPA vacuuming and sanitization where remediation was performed.
Materials and Equipment That Perform in West Texas
We use 20‑mil reinforced liners rated to ASTM E1745 Class A, sealed with butyl/acrylic tapes and secured with termination bar. Under the liner, we add dimpled drainage matting to channel water to a sump with a reliable pump, check valve, and optional alarm/backup. For humidity, we install crawl‑space dehumidifiers (70–100 pints/day) and include a hygrometer/data logger so you can verify RH stays within 45–55 percent.
Precision matters. We survey grades with laser levels, locate cold spots with infrared imaging, and verify pump performance with test kits. The materials and measurements underpin a system that’s durable, serviceable, and easy to maintain.
Local Knowledge and Reliable Service
Seagraves sits on the windy Llano Estacado, where dust infiltration, irrigation practices, and sudden downpours can push moisture into pier‑and‑beam homes. We tailor solutions for Gaines County soils and weather - vent sealing and rim‑joist air sealing to block dust, drainage for storm events, and insulation strategies that match West Texas energy goals.
Expect prompt scheduling, clear communication, and respectful crews. We offer free inspections, photo reports, and straightforward pricing so you can make a confident decision. Most projects are completed in 1–3 days with minimal disruption.

Frequently Asked Questions
Is crawl space encapsulation worth it in Texas?
Yes. Even in West Texas, encapsulation stops ground moisture, protects floor framing, and reduces musty air leaking into the home. Sealing with a Class I vapor barrier, adding drainage where needed, and controlling humidity with a dehumidifier can help lower energy use and extend HVAC life. Many homeowners also notice fewer allergens and a more comfortable home year‑round.
How much does crawl space encapsulation cost near Seagraves and West Texas?
Most projects range from $4,500–$15,000 in our region, depending on size, access, drainage needs, liner thickness (10–12 mil vs 20 mil), dehumidifier sizing, and repairs (mold/wood rot/joists). Sump pumps or French drains add cost but are essential if water collects. We provide a detailed written scope and fixed pricing after a free inspection, and financing options are available.
What thickness vapor barrier is best - 10–12 mil or 20 mil?
We recommend a reinforced 20‑mil liner that meets ASTM E1745 Class A performance for durability, puncture resistance, and low permeance. While 10–12 mil products can work in light‑traffic areas, 20 mil stands up to service access and reduces the risk of tears. We mechanically fasten the liner up walls and seal seams with butyl/acrylic tapes for a long‑term seal.
Do I need a dehumidifier after encapsulating a crawl space?
Usually, yes. IRC R408.3 requires mechanical drying in unvented crawl spaces - either dehumidification, minimal supply air, or an exhaust fan. We typically install a crawl‑space dehumidifier (70–100 pints/day) with a condensate pump and maintain RH at 45–55 percent. This protects wood framing, discourages mold, and ensures the vapor barrier performs as designed.
What are the IRC R408.3 requirements for an unvented crawl space?
R408.3 calls for a sealed Class I vapor retarder over soil, extended up walls, sealed seams and penetrations, closed vents, and mechanical drying (dehumidifier, exhaust at 1 CFM per 50 sq ft, or limited supply air from the HVAC). Insulation is typically at the foundation walls with rim‑joist air sealing. We design and document systems to align with these provisions.
Which vapor retarder class (ASTM E1745) should I choose for my Seagraves crawl space?
Choose an ASTM E1745 Class A vapor retarder for the best tensile strength, puncture resistance, and low water vapor transmission. We use reinforced 20‑mil liners that meet Class A performance and secure them with termination bar, masonry fasteners, and high‑quality tapes. This spec helps your system last 15–25 years with routine maintenance.
Is encapsulation necessary in Seagraves’ drier West Texas climate?
Yes - dry doesn’t mean moisture‑free. Wind‑driven dust, irrigation, periodic storms, and plumbing leaks can push moisture into pier‑and‑beam crawl spaces. Encapsulation blocks ground vapor, improves air quality, and stabilizes floors. Combined with drainage and a dehumidifier, it prevents mold and wood rot while improving comfort and potentially lowering energy bills.
Do I need a termite inspection gap or pest treatments in Gaines County?
We maintain a visible inspection gap at the top of wall insulation/liner so pest pros can see termite activity. If you have an active infestation or high pest pressure, we coordinate with your pest control provider and can add pest‑resistant barriers at vents and doors. Encapsulation also helps deter critters by sealing entry points and reducing moisture.
How long does a crawl space encapsulation last?
With Class A 20‑mil liners, quality tapes, proper fastening, and humidity control, encapsulations typically last 15–25 years. Dehumidifiers often last 5–10 years with filter changes and annual service. We offer maintenance plans that include RH checks, liner/penetration inspections, and sump testing to keep everything performing.
Can I DIY my crawl space encapsulation?
Small patching is DIY‑friendly, but full encapsulation is challenging: confined‑space safety, mold handling, electrical (GFCI/dedicated circuits), plumbing for discharge, and code details like R408.3 mechanical drying. Mistakes can trap water or void warranties. We recommend a free professional inspection and a documented plan; we’re happy to explain each step and your options.
