Crawl Space Services Built for West Texas Homes
We fix moisture, humidity, and structural issues under your home using durable materials and code‑compliant methods. Every project includes a detailed inspection, photos, and a clear scope of work.
Crawl Space Waterproofing
Recurring puddles or seasonal flooding can damage joists and promote mold. We install interior drainage trenches with perforated pipe and washed gravel, a sump basin with check valve, and reliable pumps to route water away. Where needed, we add dimpled drainage matting beneath the liner to relieve hydrostatic pressure. Our team uses laser levels to set trench grades and moisture meters to verify dry‑down. Learn more about our Crawl Space Waterproofing services.
Crawl Space Vapor Barrier Installation
Soil moisture vapor drives odors and humidity into living spaces. We install 12–20 mil reinforced polyethylene liners meeting ASTM E1745 Class A, with overlapped seams rolled tight and sealed with butyl tape. Termination bars and polyurethane sealant mechanically fasten the liner up foundation walls and around piers. The result is a clean, sealed surface that stops ground moisture and improves indoor air quality. Learn more about our Crawl Space Vapor Barrier Installation services.
Crawl Space Dehumidifier Installation
In a sealed crawl space, a right‑sized dehumidifier maintains ideal RH (45–55%). We install Aprilaire or Santa Fe units with condensate pumps on dedicated circuits, and place them for even airflow. For a 1,500 sq ft crawl space, we typically recommend 70–100 pints/day capacity based on cubic footage and leakage. Data loggers verify performance after startup. This protects wood framing, helps control odors, and stabilizes floors. Learn more about our Crawl Space Dehumidifier Installation services.
Crawl Space Insulation Installation
Poor or missing insulation leads to cold floors in winter and energy loss in summer. We install continuous perimeter wall insulation (rigid foam board or closed‑cell spray foam) per IECC Zone 3B best practices, leaving a termite inspection gap at the top. Where appropriate, we replace failing fiberglass with rigid foam and add air sealing at penetrations. This improves comfort and can reduce energy bills in the hot‑dry West Texas climate. Learn more about our Crawl Space Insulation Installation services.
Crawl Space Structural Repair
High humidity and long‑term leaks can cause wood rot and sagging floors. Our crews sister joists, replace beams and posts, and add steel‑adjustable piers when needed. We pair repairs with moisture control (vapor barrier, drainage, sealing) to stop the problem at its source. All work follows IRC guidelines, using treated lumber, stainless/galvanized fasteners, and verified load paths. Learn more about our Crawl Space Structural Repair services.

Why Choose Odessa Crawl Space for Dawson County Homes
Odessa Crawl Space brings deep building‑science expertise to every project in the South Plains. We’re local, fully insured, and focused on long‑term results - not quick fixes. Our process combines drainage, an ASTM‑rated vapor barrier, air sealing, and right‑sized dehumidification to protect your home. If you’re searching for Crawl Space Encapsulation Dawson County TX, trust a team that stands behind its work.
Certified Expertise and Proven Process
Our specialists are trained in IICRC water‑damage best practices and OSHA 10/30 Construction Safety, and we follow ICC/IRC guidance for unvented crawl spaces. We apply BPI building‑enclosure principles to manage moisture, air, and thermal layers - so your crawl space works as a system.
We document every step with photos and measurements. Moisture meters, hygrometers, and thermal imaging help pinpoint sources of humidity and air leaks before we recommend solutions. That means smarter scopes and fewer surprises during installation.
Recent example: In June 2024, we encapsulated a 1,200 sq ft farmhouse near Welch (79377) using a 20 mil liner, dimpled matting, and an Aprilaire dehumidifier. Subfloor humidity dropped from 72% to 51% within 10 days.
Safety, Licensing, and Code Compliance
We work safely in confined spaces using PPE, respirators (P100), HEPA vacuums, and negative air machines when necessary. Our crews follow OSHA confined‑space awareness and dust‑control practices suited to West Texas crawl spaces.
We adhere to IRC R408 for unvented crawl space requirements and IRC R316 for foam plastics and ignition‑barrier rules. Vapor barriers meet ASTM E1745 performance classes. Where electrical, plumbing, or HVAC tie‑ins are required, we coordinate with properly licensed Texas contractors (TDLR, TSBPE) and pull city/county permits when applicable.
Materials and Equipment That Last
We install 12–20 mil reinforced liners, mechanically fastened with termination bars and polyurethane sealant - no shortcuts. Seams are overlapped, rolled, and taped with butyl tape for a continuous air and vapor seal, including at piers and utility penetrations.
For conditioning, we use Aprilaire and Santa Fe dehumidifiers with condensate pumps and data logging. Drainage systems include perforated pipe, washed gravel, and basins with check valves. Precision tools - laser levels, manometers (for pressure checks), and moisture meters - ensure your system performs as designed.
West Texas Local Knowledge
From Lamesa to Ackerly and Los Ybanez, we understand hot‑dry IECC Zone 3B conditions, wind‑driven dust, and expansive soils on the Llano Estacado. Vented crawl spaces can pull dust and humidity into living areas; we stop that with vent sealing and pressure‑balanced conditioning.
We also consider real‑world constraints - limited municipal storm sewers in rural areas, irrigation runoff, and farm/ranch site grading. Our team designs practical discharge routes and, when needed, phased projects that fit budgets without compromising results.
Customer‑First Policies and Warranties
Every proposal includes clear pricing, scope, and options (good/better/best), including financing options on request. We offer workmanship warranties and pass through manufacturer warranties on liners and dehumidifiers. After installation, you’ll receive maintenance guidance and optional service plans to keep RH in the target range year‑round.
Have an appraisal or sale coming up? We provide photo documentation and real‑estate friendly summaries, and we can coordinate mold remediation if required before encapsulation.

Frequently Asked Questions
What is crawl space encapsulation and how does it work?
Encapsulation seals the crawl space from soil and outdoor air. We install a 12–20 mil reinforced liner on the ground and up walls, seal vents and penetrations, add perimeter insulation, and control humidity with drainage and a dehumidifier. Seams are overlapped, rolled, and taped; walls are mechanically fastened with termination bars and sealant. The system reduces moisture, odors, and dust while protecting framing and improving comfort in Dawson County homes.
Is crawl space encapsulation worth it in Texas?
Yes - especially for pier‑and‑beam homes in the South Plains. A sealed system limits West Texas dust infiltration, stabilizes humidity to 45–55%, reduces musty odors, and can lower energy use by insulating and air‑sealing the floor assembly. In Lamesa and Welch, we often see floor comfort improve immediately and subfloor moisture readings drop within days. Preventing wood rot and mold risk can also protect your home’s value.
How much does crawl space encapsulation cost near Dawson County?
Most projects range from $4,500–$14,000 depending on size, access, drainage needs, liner thickness (12–20 mil), and whether insulation and dehumidification are included. Larger or complex jobs with interior French drains and sump pumps can exceed $18,000. We provide free inspections, a written scope, and phased options if you prefer to start with a vapor barrier and vent sealing before adding a dehumidifier.
Do I need a dehumidifier after encapsulation?
In IECC Zone 3B (hot‑dry), a dedicated dehumidifier is the most reliable way to maintain target RH year‑round. We right‑size units based on square footage, height, leakage, and measured conditions - often 70–100 pints/day for a 1,500 sq ft crawl space. We also discuss conditioned‑air supply options, but a dehumidifier with data logging provides consistent control and easier maintenance.
How thick should a crawl space vapor barrier be?
We recommend 12–20 mil reinforced polyethylene meeting ASTM E1745 (Class A vapor retarder for durability). Thicker liners resist punctures during service and offer better long‑term performance. We pair the liner with dimpled drainage matting where bulk water is present, and we always fasten the liner up walls with termination bars and polyurethane sealant for a long‑lasting seal.
What are Dawson County’s IECC climate considerations (Zone 3B hot‑dry) for sealed crawl spaces?
Zone 3B favors unvented, insulated crawl spaces with controlled RH. We focus on air sealing (vents and penetrations), continuous perimeter wall insulation (rigid or closed‑cell foam) with an ignition barrier as required by IRC R316, and humidity control via dehumidifier. Dust control is also key in West Texas, so we maintain positive sealing and robust access‑door weatherstripping.
Can encapsulation help with West Texas dust infiltration and indoor air quality?
Yes. Vented crawl spaces can pull in dust and outdoor allergens, which then move upward into living areas. By sealing vents, installing an ASTM‑rated vapor barrier, and controlling pressure with a dehumidifier, we reduce dust entry and odor transfer. Many Dawson County clients report clearer indoor air and fewer musty smells after we complete encapsulation and air sealing.
How do you maintain a termite inspection gap when insulating crawl space walls?
We leave a 2–3 inch inspection gap at the top of wall insulation per regional best practices and pest‑control recommendations. Rigid foam is cut to maintain this gap, and the liner is terminated below it using termination bars and sealant. If requested, we coordinate with a licensed pest professional to install shields or provide guidance on inspection access in Texas.
Do homes in Lamesa and Welch typically have crawl spaces or slab foundations - and how does that change the solution?
You’ll find both slab and pier‑and‑beam homes across Dawson County. Slabs usually need exterior drainage solutions, while pier‑and‑beam homes benefit from encapsulation, wall insulation, and dehumidification. In Lamesa (79331) and Welch (79377), many older farmhouses are pier‑and‑beam; we tailor solutions to access conditions, height, and soil moisture, often adding interior drainage and a sump for reliability.
What warranties are available on liners, dehumidifiers, and workmanship for crawl space encapsulation?
We provide a written workmanship warranty and register manufacturer warranties for liners and dehumidifiers. Most reinforced liners carry long‑term manufacturer coverage, and dehumidifiers typically include multi‑year parts warranties (brand‑specific). You’ll receive maintenance guidance and optional annual service checks to verify humidity control and system performance over time.
