How GreenFiber Products Fail - and How We Fix Them

• GreenFiber Sanctuary II vapor barriers degrade at seam tape in New Braunfels crawl spaces. The adhesive backing on factory seams loses tack when subjected to the 70+ percent relative humidity common beneath homes off River Road and along the Guadalupe corridor. We cut back failed seams, install 12-mil reinforced polyethylene with mechanical fastening at 12-inch intervals, and seal with butyl tape rated for continuous moisture exposure rather than relying on pressure-sensitive adhesive alone.
• GreenFiber Low-Settle blown insulation absorbs ground moisture when the vapor barrier beneath it breaches. The cellulose binder breaks down, the material compacts to half its installed depth, and R-value drops from stated R-19 to effectively R-8 or lower. We remove saturated material, dry the cavity with commercial dehumidification if needed, reinstall a sealed vapor barrier, and replace with fresh GreenFiber only after confirming the moisture source is eliminated.
• GreenFiber Stabilized Cellulose in vented crawl spaces wicks humidity through foundation block walls. In older New Braunfels homes near downtown with unsealed CMU foundations, the borate treatment eventually washes out at the bottom two feet of installation. We document this with moisture-meter readings and photos, then recommend full encapsulation with closed-cell spray foam at the rim joist rather than repeated cellulose replacement.
• GreenFiber subfloor insulation hangers corrode in high-alkalinity soil conditions common in Comal County. The wire staples or polypropylene straps fail, dropping batts or blown-in blankets onto the crawl floor. We switch to stainless-steel fasteners or suspended mesh systems on replacement jobs, and we note this in the written scope so the homeowner knows the fix outlasts the original installation.
• GreenFiber retrofit jobs over unsealed crawl spaces create trapped moisture layers. When a previous contractor installed GreenFiber insulation without first addressing dirt-floor evaporation or perimeter leaks, the insulation becomes a reservoir. We run a blower-door test - a pressurization reading that shows, in one number, how much conditioned air the house leaks - to identify stack-effect pull from the crawl, then seal before insulating. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.

Our GreenFiber Crawl Space Encapsulation & Vapor Barrier Process

1. 1
   Call and scheduling. A live person answers, books a diagnostic window, and texts when the technician is en route. Under Haven Standard: Arrive on schedule, you get a named technician.
2. 2
   On-site diagnostic. We inspect the GreenFiber system for moisture damage, measure existing insulation depth, photograph all findings, and run a blower-door test if air leakage into the crawl is suspected.
3. 3
   Written scope and price. We deliver a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1, no exceptions.
4. 4
   Parts decision. We use GreenFiber-compatible materials - virgin polyethylene vapor barriers, conditioned borate cellulose when replacement is warranted - or quality aftermarket equivalents with documented specs. No proprietary lock-in.
5. 5
   Execution and documentation. Crew completes the encapsulation or vapor barrier repair, photographs the finished work, and provides before-and-after readings where applicable.
6. 6
   Closeout. Homeowner receives printed blower-door results, photo record, and written warranty. The 365-Day Done Right Promise applies from this date.

What GreenFiber Crawl Space Encapsulation & Vapor Barrier Costs in New Braunfels

What moves the price: crawl square footage, accessibility height, whether the existing GreenFiber is wet and must be removed, and whether the home needs active dehumidification or passive sealing suffices. Homes in the Hill Country terrace zones above the Guadalupe tend to have drier crawl conditions; homes in the floodplain neighborhoods near Landa Park or the Comal River corridor more often need full encapsulation with sump consideration.
