Core Crawl Space Services in Rankin Built for West Texas Homes
We focus on long‑lasting moisture control, air sealing, and structural protection under your home. Every project follows code and safety best practices, with materials selected for the Permian Basin environment.
Crawl Space Vapor Barrier Installation
Moist soil and wind‑driven dust lead to odors, cupping floors, and insulation failure. We install ASTM E1745 Class A reinforced liners (12–20 mil) with butyl seam tape, mastic, and termination bars up walls. Piers are wrapped and sealed; seams overlap 6–12 inches. Where traffic is expected, we add dimpled drainage mat for durability. The result is a clean, sealed crawl that reduces vapor, dust, and pests.

Crawl Space Waterproofing
If groundwater or plumbing leaks leave standing water, encapsulation alone won’t hold. We design interior drainage to a sealed sump basin with a check valve and optional battery backup. Discharge lines are routed per best practice to daylight. After water control, we install the liner and humidity management for a complete system. This protects joists from rot and helps preserve flooring and indoor air quality. Learn more about our Crawl Space Waterproofing services.
Crawl Space Dehumidifier Installation
To maintain 45–55% RH year‑round, we install high‑capacity dehumidifiers (70–120+ pints/day), such as Santa Fe or Aprilaire. Units are set on protection mats, connected to a dedicated GFCI outlet, and piped with a condensate drain to the exterior. We add remote hygrometers for easy monitoring. This stops musty odors and mold growth and protects wood framing in the Rankin climate. Learn more about our Crawl Space Dehumidifier Installation services.
Crawl Space Insulation Installation
Falling fiberglass and air leaks at rim joists waste energy and invite pests. We air‑seal penetrations and install rigid foam board (XPS/EPS) at R‑10 or apply closed‑cell spray foam at rim/band joists per project needs. This improves comfort, reduces drafts, and supports energy savings. Our crews use thermal cameras and moisture meters to verify results. Learn more about our Crawl Space Insulation Installation services.
Crawl Space French Drain Installation
When perimeter seepage is present, an interior French drain paired with a sealed sump pump is the most reliable solution. We cut neat trenches, pitch pipe with a laser level, and route to a sump with a tight lid to protect air quality. After water control, we encapsulate for a dry, clean space that lasts.

Why Homeowners Choose Us for Crawl Space Encapsulation in Rankin, TX
Odessa Crawl Space brings local expertise, proven materials, and clear communication to every project. We’ve helped thousands of Permian Basin homeowners stop moisture, dust, and pests under their homes. Our systems follow IRC R408 unvented crawl requirements, NEC GFCI rules, and OSHA safety practices. If you’re comparing options for Crawl Space Encapsulation Rankin TX, count on us for dependable results and honest pricing.
Certified Know‑How and Quality Standards
Our team follows BPI building science principles to solve the root causes of crawl space issues, not just the symptoms. For mold‑related work, we provide IICRC WRT/AMRT trained technicians and coordinate TDLR‑licensed remediation when required. We also maintain BBB Permian Basin accreditation and manufacturer training for liners and dehumidifiers.
Every installation uses ASTM E1745 Class A reinforced liners, butyl tape, termination bars, and proper wall/column wrapping. We verify performance with hygrometers and moisture meters, so you see humidity drop to 45–55% RH and wood moisture content stabilize.
Safety, Licensing, and Code Compliance
We protect your home and our crews with OSHA 10/30 training, proper PPE, confined‑space procedures, and jobsite ventilation. Electrical work for dehumidifiers or sump pumps includes GFCI‑protected receptacles per NEC and, when needed, permit coordination with Upton County or the City of Rankin.
We preserve termite inspection requirements by leaving a visible gap (commonly ~3 inches) below the sill where required, and we coordinate with a TDA‑licensed pest professional when termite shields or treatments are needed. Your warranty remains intact because the details are done right.
Built for West Texas Winds, Dust, and Pests
Rankin’s semi‑arid climate and wind events push dust through vents and gaps. We use UV‑stable exterior vent covers with gaskets, seal penetrations, and, when requested, add dust‑tight vent blocking. For pest resistance, we close typical entry points and can coordinate pest exclusion with licensed partners.
Need an extra‑tough floor? We offer optional fiber‑reinforced rat slab (thin concrete over dirt) to resist traffic and soil gases in uneven crawls, especially helpful for oilfield housing and older pier‑and‑beam homes.
Proven Results, Warranties, and Local Support
In March 2024 near 79778, we encapsulated a 1,600 sq ft pier‑and‑beam home with a 20 mil liner, interior drain to a sealed sump, and a 90‑pint dehumidifier. Crawl humidity fell from 72% to 48% in 48 hours, and odors disappeared.
You’ll receive a written scope, photos, and a warranty on materials and workmanship. We provide bilingual service (English/Spanish) and annual maintenance with humidity monitoring so your system keeps performing year after year.

Frequently Asked Questions
What is crawl space encapsulation and what does it include?
Encapsulation seals your crawl space from earth and outside air to control moisture, dust, and pests. We install an ASTM E1745 Class A liner (typically 12–20 mil), wrap and seal piers, run the liner up walls with termination bars, and seal vents and penetrations. If water is present, we add interior French drains and a sealed sump pump before the liner. A high‑capacity dehumidifier maintains 45–55% RH, with a dedicated condensate drain and GFCI outlet.
Do I need drainage or a sump pump before encapsulating?
Yes, if you have standing water or chronic seepage. Encapsulation traps moisture in place unless we route it out. In Rankin and Upton County, we often install an interior French drain pitched to a sealed sump basin with a check valve and optional battery backup. After water control is verified, we encapsulate and add humidity management for a permanent fix.
Should crawl space vents be closed and do I need a dehumidifier?
For sealed crawls, vents are closed and gasketed to stop dust, pests, and humid air. We then condition the space with a dedicated dehumidifier sized to your square footage and leakage (often 70–120+ pints/day). This approach is consistent with IRC R408 allowances for unvented crawl spaces and keeps humidity stable in Rankin’s changing seasons.
What material thickness is best for a crawl space liner?
We recommend a reinforced 12–20 mil vapor barrier rated to ASTM E1745 Class A. Thicker (e.g., 20 mil) is ideal for high‑traffic areas and oilfield‑area homes where service access is common. We also add dimpled drainage mat where durability is critical. Proper butyl seam taping, mastic, and mechanical fastening matter as much as thickness.
How much does crawl space encapsulation cost near Rankin TX?
Costs vary with size, access, drainage needs, and equipment. Simple vapor barrier projects can be a few thousand dollars; full systems with French drain, sealed sump, 20 mil liner, and a dehumidifier scale higher. We provide a free crawl space inspection, photos, and a line‑item estimate so you can choose the right scope for your home and budget.
What maintenance is required after encapsulation?
We recommend an annual check to confirm seams are intact, the liner is secure, and humidity remains at 45–55% RH. Dehumidifier filters should be cleaned or replaced, and the condensate line verified for clear flow. If you have a sump pump, test operation and backup power. We offer maintenance plans with remote humidity monitoring for convenience.
Is there a required termite inspection gap with encapsulation in Texas?
Many termite providers require a visible inspection gap (commonly ~3 inches) below the sill along the foundation wall. We honor that detail during installation to preserve your termite bond and make inspections easier. When termite shields or treatments are needed, we coordinate with TDA‑licensed pest professionals serving Rankin and surrounding areas.
Can encapsulation reduce West Texas dust and keep out scorpions/rodents?
Yes. By sealing vents with UV‑stable covers and gaskets, air‑sealing penetrations, and installing a durable liner, we greatly cut dust infiltration and common pest entry points. For stubborn conditions, we add dust‑tight vent blocking and door upgrades. Encapsulation also makes pest inspections and monitoring far easier in the Permian Basin.
Can I add a thin concrete “rat slab” before encapsulation?
Absolutely. A fiber‑reinforced rat slab (thin concrete over the soil) creates a durable, even surface that resists soil gases and traffic damage. We typically pour it after drainage is installed and before the liner. It’s a smart upgrade for uneven dirt crawls, manufactured homes, or oilfield housing that sees frequent under‑house access.
Will encapsulation improve indoor air quality and energy efficiency?
Sealing the crawl reduces musty odors, mold risk, and particulate infiltration from the ground. Air‑sealing and insulating rim joists, plus controlled humidity, help stabilize indoor comfort and can reduce HVAC runtime. Customers in Rankin often report quieter floors, fewer drafts, and fresher indoor air within days of project completion.
