Crawl Space Services That Stop Moisture at the Source

We design and install sealed, code‑compliant systems that control moisture, protect structure, and improve indoor air. Every project includes thorough inspection, documentation, and clear pricing.

Crawl Space Waterproofing

Water and soil vapor drive mold, odors, and wood rot. We stop it with a complete waterproofing plan: drainage matting, an interior drain where needed, a sealed sump basin and discharge line, and a continuous liner up the foundation walls with termination bar. Our team uses moisture meters and hygrometers to verify results and targets 45–55% RH after completion. Learn more about our Crawl Space Waterproofing services.

Crawl Space Vapor Barrier Installation

Thin plastic sheeting won’t hold up in West Texas. We install reinforced polyethylene liners (12–20 mil) that meet ASTM E1745 Class A, overlap seams 6–12 inches, and roll/tape with butyl and acrylic tapes. We wrap and seal piers, mechanically fasten to the wall, and leave a termite inspection gap per Texas pest control guidance. Learn more about our Crawl Space Vapor Barrier Installation services.

Crawl Space Dehumidifier Installation

After sealing, we control humidity with high‑efficiency units sized for your square footage and leakage. We commonly install Santa Fe or Aprilaire dehumidifiers with dedicated condensate routing, optional pump, and service pad. Our technicians set targets to maintain 45–55% RH and can add a monitor for remote readings. Electrical work is performed to code by a licensed electrician when needed. Learn more about our Crawl Space Dehumidifier Installation services.

Crawl Space Drainage System Installation

If ground water or perimeter seepage is present, we address it before sealing. We add dimpled drainage matting, an interior drain to a sump basin, and a clog‑resistant discharge line with check valve routed to daylight per code. A laser level ensures proper pitch, and protection mats prevent damage during service. Learn more about our Crawl Space Drainage System Installation services.

Crawl Space Sump Pump Installation

Our sealed basins with primary pumps (and optional battery backup) manage sudden storms and protect your encapsulation. We size pumps to anticipated inflow, add backflow prevention, and provide labeled shutoffs for easy maintenance. After commissioning, we test cycle and document performance.

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

Since 2009, Odessa Crawl Space has helped thousands of West Texas homeowners eliminate crawl space moisture problems for good. Our process blends building science with practical field experience, delivering durable results that protect your structure and air quality. We’re licensed and insured, follow OSHA confined‑space procedures, and document every job with before/after readings. For Crawl Space Encapsulation Seminole TX homeowners can rely on, we stand behind our work with written warranties.

Certified Expertise and Proven Process

Moisture issues are building‑science problems, not just “plastic on dirt.” Our team includes technicians trained to BPI standards and IICRC WRT/AMRT for water and microbial remediation. We start with a detailed crawl space inspection - wood moisture content, ambient RH, and visible intrusion points - then design a system to reach 45–55% RH.

We follow best practices: install drainage first if needed, use ASTM E1745 Class A liners, overlap and tape seams 6–12 inches, and mechanically fasten the liner with termination bar. Penetrations and piers are detailed airtight, and rim/band joists are insulated appropriately for sealed systems.

Safety, Licensing, and Code Compliance

Your home and our crews are protected. We carry general liability and workers’ comp, use PPE, and follow OSHA 29 CFR 1926 Subpart AA for confined spaces. When mold is present, we adhere to TDLR rules and use HEPA vacuums and negative air where appropriate.

We build to IRC R408 (unvented/conditioned crawl spaces) and leave the required termite inspection strip. Electrical needs for dehumidifiers or sump pumps are handled by a licensed electrician, with permits pulled when required, ensuring long‑term safety and compliance.

Purpose‑Built Materials and Equipment

We install reinforced polyethylene liners (12–20 mil) matched to conditions, use butyl and acrylic seam tapes, and secure with mechanical fasteners. Dimpled drainage matting protects the liner and promotes flow to an interior drain.

Our dehumidifier lineup features high‑efficiency Santa Fe and Aprilaire units with reliable condensate routing. We rely on laser levels, moisture meters, and seam rollers to ensure tight detailing, correct pitches, and measurable results.

West Texas Know‑How

Seminole and Gaines County see wind‑driven dust, occasional intense rains, and caliche soils. We design for these realities - sealing vents, protecting liners in traffic areas, and sizing pumps and discharge lines to handle quick downpours.

Frequently Asked Questions

What is included in a crawl space encapsulation system?

A complete system seals ground and walls with an ASTM E1745 Class A liner, details all seams and piers, closes vents, and adds insulation at the walls or rim joists. If water is present, we install drainage and a sump first. A high‑efficiency dehumidifier (Santa Fe or Aprilaire) maintains 45–55% RH with a dedicated condensate drain. We document pre/post moisture readings and provide maintenance guidance for long‑term performance in Seminole’s 79360 climate.

Do I need drainage or a sump pump before encapsulating?

Yes - if there’s liquid water or signs of periodic intrusion, we address that before sealing. We install dimpled drainage matting, an interior perimeter drain pitched to a sealed basin, and a sump with check valve and exterior discharge. Without drainage, water can bypass the liner and pool. Our inspection includes laser level checks and water‑trail mapping to recommend the right solution for your Seminole home.

How long does crawl space encapsulation take?

Most Seminole projects take 1–3 days depending on size, access, remediation needs, and whether drainage/sump installation is required. We stage materials, protect entry points, and keep the jobsite tidy. After installation, we test dehumidifier operation, verify discharge lines, and record final RH and wood moisture. You’ll receive photos and a written warranty at completion.

How thick should the vapor barrier be (12–20 mil)?

We match thickness to site conditions. For most West Texas crawl spaces, a reinforced 12–15 mil is sufficient; heavy‑traffic or rough surfaces may call for 20 mil. The key is using a reinforced polyethylene that meets ASTM E1745 Class A and installing it correctly: overlaps taped, piers wrapped, walls terminated with bar, and protection mats in service paths.

Should crawl space vents be closed in West Texas?

Yes, when you build an unvented, conditioned crawl space under IRC R408.3. Open vents invite dust, humidity swings, and pests. We air‑seal vents with durable panels, insulate the rim/band joist, and condition or dehumidify the space to stabilize RH. We also maintain a termite inspection gap per Texas guidelines.

How much does crawl space encapsulation cost near Seminole, TX?

Costs vary with size, access, and whether you need drainage, sump, mold remediation, or structural repairs. Typical projects range from a few thousand dollars for straightforward vapor barrier upgrades to more for full systems with drainage and a dehumidifier. We provide a free crawl space inspection in 79360 and a same‑day written estimate with options.

Do I need a dehumidifier after encapsulation?

In most cases, yes. Even with an excellent vapor barrier, wood and foundation walls release moisture. A right‑sized unit (often 70–120 pints/day for typical homes) keeps RH in the ideal 45–55% range, reducing odors and protecting framing. We install Santa Fe or Aprilaire units with proper condensate routing and service pads.

Will encapsulation help with sagging floors or structural issues?

Encapsulation controls the moisture causing wood to soften, but sagging may require structural repairs. We can pair your project with jack posts, beam/pier repairs, or joist sistering to re‑level and stabilize the floor system. Drying the environment prevents future movement and protects new supports.

What maintenance is required after encapsulation?

Plan an annual check: verify dehumidifier operation and filter, inspect discharge lines, confirm RH stays 45–55%, and spot‑check liner seams and the termite gap. Our team offers maintenance visits and can install remote monitoring. You’ll receive a simple care guide and warranty documentation after your project.
