Crawl Space Sealing, Insulation, and Moisture Control Services

We focus on durable, code-aligned crawl space repairs that stop moisture, soil gases, and dust at the source. Every project is engineered for West Texas conditions and backed by clear documentation and a written warranty.

Crawl Space Vapor Barrier Installation

Moisture and soil odors migrate up through bare soil, fueling mold and musty air. We install a reinforced polyethylene liner (12–20 mil), lap and tape seams with butyl tape, wrap and seal piers, and mechanically fasten the liner to walls. A dimpled drainage mat can be added where soils are uneven. We leave a termite inspection strip per local pest guidance. This creates a continuous moisture barrier that improves indoor air, protects framing, and supports energy savings. Learn more about our Crawl Space Vapor Barrier Installation services.

Crawl Space Dehumidifier Installation

Even sealed crawls can need active humidity control to hold 45–55% RH year-round. We size and install a high-efficiency dehumidifier with a condensate pump and dedicated drain. Optional dedicated electrical circuits are coordinated with a licensed electrician as required. We add humidity sensors for ongoing monitoring. The result: stable humidity, reduced odors, and protection against mold recurrence in the Iraan climate. Learn more about our Crawl Space Dehumidifier Installation services.

Crawl Space Drainage System Installation

If water enters during storms or from uphill lots, we install an interior perimeter drain (perforated drain tile and gravel) to a sealed sump basin with a check valve and exterior discharge. Battery backup options keep water moving during rural outages. We test with a sump pump kit and document flows. This keeps the liner dry and prevents standing water, making the entire encapsulation perform as designed. Learn more about our Crawl Space Drainage System Installation services.

Crawl Space Insulation Installation

We insulate crawl space walls with rigid foam board (EPS/XPS) and air-seal rim joists with closed-cell spray foam for better comfort and energy performance. Our team weighs wall versus subfloor insulation based on ducts location, access, and code. We seal penetrations with polyurethane foam and install a weatherstripped, insulated access door. Expect warmer floors in winter and fewer drafts. Learn more about our Crawl Space Insulation Installation services.

Crawl Space Mold Removal & Remediation

Musty odors, staining, and high moisture are addressed with IICRC-informed practices. We HEPA vacuum surfaces, treat framing with a borate solution, and, when needed, use gentle surface blasting to remove staining. Encapsulation and dehumidification keep RH in check to prevent recurrence. Pre- and post-readings with a moisture meter/hygrometer verify results.

Why Choose Odessa Crawl Space for Crawl Space Encapsulation in Iraan, TX

Homeowners in Pecos County trust Odessa Crawl Space for solutions that meet code and perform in West Texas conditions. We diagnose with moisture meters and infrared tools, then design sealed, conditioned crawl spaces that stop dust and humidity at the source. From vapor barriers to dehumidifiers and drainage, our team delivers measured results - often within 24–48 hours. It’s why residents search for Crawl Space Encapsulation Iraan TX and call us first.

Code-Aligned Solutions and Documented Results

We build to the intent of IRC Section R408.3 for unvented/conditioned crawl spaces. That includes closing vents, installing a continuous vapor retarder, and providing conditioning via supply air, mechanical exhaust, or a dedicated dehumidifier - whichever best fits your home and Climate Zone 3B.

Before we start, we log baseline readings with a hygrometer and moisture meter. After installation, we verify RH and wood moisture content, targeting 45–55% RH. You’ll receive photo documentation and readings for your records - useful for resale or insurance.

Materials and Methods That Last in West Texas

We specify Class I reinforced polyethylene liners (12–20 mil) with a 6–12 inch wall upturn, butyl seam tape, and mechanical fastening strips with masonry anchors. Around piers, we wrap and seal for continuity. Where soils are uneven, we add a dimpled drainage mat for durability.

Rim joists are air-sealed with closed-cell spray foam; walls can be insulated with rigid foam (EPS/XPS) as needed. Access doors are upgraded with insulated, weatherstripped panels that also help dust exclusion - critical in the Trans-Pecos wind.

Drainage and Power Resilience

For sites with stormwater issues, we install an interior French drain to a sealed sump basin with a check valve and exterior discharge. We test every pump and offer battery backup options to handle rural outages common around Iraan, Rankin, and McCamey.

We also extend downspouts, check grading, and can add a transfer pump where elevations require it. Keeping water out protects the encapsulation and your structure.

Pest and Termite-Aware Design

We coordinate with your pest professional and maintain a visible inspection gap at the sill so termite monitoring remains effective. Termite shields or inspection strips can be added per local guidance to keep warranties intact.

All penetrations are sealed with polyurethane foam/sealant, and vent openings are closed with rigid covers - reducing entry points for pests and dust without compromising inspection access.

Local Experience and Real Results

We work on pier-and-beam homes, oilfield housing, and historic low-clearance crawls throughout the Permian Basin. Example: In August 2024 near Alley Oop Park, a 1,100 sq ft crawl had 72% RH and musty odors. After drainage, a 12-mil liner, and a 70-pint dehumidifier, RH dropped to 50% in 48 hours and odors were gone.

That’s the difference of a system approach - diagnose, design, install, and verify - built for Iraan’s arid, windy conditions.

Frequently Asked Questions

What is crawl space encapsulation and what does it include?
Encapsulation seals the crawl from soil and outdoor air to control humidity, odors, and dust. In Iraan we typically install a Class I vapor barrier (12–20 mil) with sealed seams, wrap and seal around piers, close vents, upgrade the access door, and add a dehumidifier or conditioned air per IRC R408.3. Drainage to a sealed sump is added when water intrusion is present. We document before/after moisture readings for your records.
Do I need drainage or a sump pump before encapsulating?
If water enters during storms or from uphill lots, yes - drainage comes first. We install an interior French drain that feeds a sealed sump basin with a check valve and exterior discharge. In Pecos County and 79744, we often add battery backup to handle rural outages. If your crawl stays dry, we may encapsulate without a sump - our assessment will confirm the best path.
Should vents be closed and will I need a dehumidifier?
For sealed crawls, vents are closed to stop unconditioned air and dust. The IRC allows conditioning by supply air, mechanical exhaust, or a dedicated dehumidifier. In West Texas, a right-sized dehumidifier is the most consistent way to maintain 45–55% RH year-round, especially after rain events. We size equipment based on cubic footage, leakage, and measured moisture.
What materials and thickness do you use for the vapor barrier?
We recommend a reinforced polyethylene Class I liner, typically 12–20 mil for durability in low-clearance spaces. Seams are overlapped, rolled tight, and sealed with butyl seam tape; walls are mechanically fastened with termination bars. We leave a termite inspection gap and seal penetrations with polyurethane foam. UV-resistant liners can be specified for high-heat applications in West Texas.
How long does installation take and do I need to leave the house?
Most Iraan projects take 1–3 days depending on size, clearance, and whether drainage is needed. You can usually stay home; we use PPE, HEPA vacuums, and negative-air practices when remediation is involved. We schedule inspections as required and provide a walkthrough when finished, including maintenance tips and target RH ranges.
How much does crawl space encapsulation cost?
Costs vary with crawl size, access, liner thickness, drainage, and dehumidifier selection. We provide a clear, itemized proposal after inspection so you can see each component - vapor barrier, insulation, sump, and equipment. Many Iraan homeowners choose phased work (drainage now, liner and dehumidifier later) to fit budget while solving urgent issues first.
Is encapsulation necessary in dry West Texas climates?
Yes - despite arid conditions, wind-driven dust, occasional heavy rain, and plumbing leaks still affect crawl spaces. Encapsulation helps control odors, protects wood from high seasonal humidity, and reduces dust infiltration. Homes with ducts in the crawl or musty rooms benefit most. We tailor designs for Climate Zone 3B and local conditions.
Will this affect termite protection or building code compliance?
We maintain a visible inspection gap near the sill to preserve termite monitoring and coordinate with your pest provider if needed. Our designs follow IRC R408.3 for unvented/conditioned crawls and R408.5 for debris removal and vapor retarder continuity. If local permits are required, we’ll guide you through the process.
What backup options keep systems running during outages?
For Iraan, Rankin, and McCamey, we often specify battery backup for sump pumps and surge-protected outlets for dehumidifiers. Where outages are frequent, we can recommend higher-capacity backups and remote humidity monitoring so you get alerts if RH rises. These options protect your crawl space investment during power interruptions.
Can I DIY crawl space encapsulation?
DIY kits rarely address drainage, code-compliant conditioning, or penetrations and piers correctly. Common issues include unsealed seams, no termination bars, and no plan for humidity control. Professional installation in Iraan ensures proper materials, fastening, and equipment sizing - plus documentation and a warranty for peace of mind.
