CertainTeed Crawl Space Encapsulation & Vapor Barrier Nationwide

CertainTeed Crawl Space Encapsulation & Vapor Barrier in Converse: What to Know First

As an independent CertainTeed service provider, we handle crawl space encapsulation and vapor barrier work on CertainTeed systems in Converse homes, typically scheduling within 48 hours and completing most jobs in one day. Most CertainTeed crawl space jobs in Converse run between $2,800 and $6,400 depending on whether we’re addressing a failing SmartDrain system, replacing degraded membrane, or full encapsulation with conditioned-air integration. We don’t do “call for pricing” - you get a written scope and flat price before anyone drives out. If you own a CertainTeed product and you’re seeing musty odors, cupping hardwood floors, or your dehumidifier running nonstop in a Converse home near FM 78 or Woodlake, this page is for you.

How CertainTeed Products Fail - and How We Fix Them

• SmartDrain sump basin cracks in the lip flange. The SmartDrain 3000 series uses a thinner polymer at the basin rim where the lid seals. In Converse’s clay-heavy soils, seasonal expansion and contraction stress that flange until it weeps groundwater around the edge, not through the pump. We replace with an OEM-grade basin or, when the homeowner prefers, a thicker-wall aftermarket unit that accepts the same CertainTeed lid geometry. Either way, we reseal with butyl tape, not silicone.
• CertainTeed vapor barrier membrane chalks and splits at fold points. The 6-mil and 10-mil polyethylene rolls CertainTeed distributes - particularly the 2018-2022 lots we see in Live Oak and Converse - degrade faster where installers creased them around piers and footings. UV stabilizers in the resin break down in dark, damp crawl spaces more than the spec sheet suggests. We pull the old membrane, treat any mold-affected joists with EPA-registered cleaner, and lay new 12-mil reinforced liner with fabric scrim, seaming with double-sided foundation tape at every overlap.
• Foundation vent seals on CertainTeed encapsulation kits lose adhesion. The foam-backed vent blocks CertainTeed supplies work until Converse’s summer humidity cycles hit 80% plus for weeks straight. The adhesive migrates, vents fall out, and outside air pours back in. We remove the failed blocks, clean the foundation to bare concrete, and install mechanical vent seals - magnetic or screw-fastened - that don’t rely on glue.
• Dehumidifier drain line freeze-ups on CertainTeed’s Aprilaire-badged units. The DH70 and DH95 models, common in CertainTeed packages, push condensate through 1/2-inch vinyl tubing that runs along cool crawl space walls. In January, when Converse dips below 32°F for a few nights, that line ices and backs up until the unit shuts on overflow. We reroute through insulated PEX or install a condensate pump with internal heat trace, depending on the crawl layout.
• SmartSump lid gasket compression set. The closed-cell foam gasket on CertainTeed SmartSump lids takes a permanent deformation after two to three years of lid traffic and humidity cycling. Radon and soil gas bypass the seal even though the lid looks seated. We measure the gasket groove, source replacement material to the original durometer, or upgrade to a bolt-down lid with silicone O-ring when the homeowner wants a longer interval between service calls.

Our CertainTeed Crawl Space Encapsulation & Vapor Barrier Process

1. 1
   Call and schedule. A live person answers, 24/7. We ask for photos if you have them, then book a diagnostic in Converse - usually within 48 hours.
2. 2
   On-site assessment and blower-door baseline. We run a blower-door test - pressurizing the house to measure air leakage in CFM50 - to establish how much conditioned air is dropping through the floor assembly into the crawl space. We photograph every pier, penetration, and membrane condition. You get a Documented Photo Record before we leave.
3. 3
   Written scope and flat price. Under Haven Standard Clause 1: written price, written scope, written warranty before anyone lifts a tool. No exceptions. If you have a competing estimate, we do a Free Second Opinion and walk through it with you.
4. 4
   Air sealing first, then barrier. We seal rim joists, sill plates, and penetrations with closed-cell foam or acoustic sealant depending on the assembly. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
5. 5
   Membrane, insulation, and mechanicals. New vapor barrier, conditioned-air duct sealing if present, dehumidifier sizing and placement, and mechanical vent seals. We use CertainTeed-compatible materials from our supplier network - Owens Corning, Johns Manville, Knauf, and others - with no proprietary lock-in.
6. 6
   Post-work blower-door and documentation. Second blower-door test, printed report showing CFM50 reduction, final photo record, and 365-Day Done Right Promise in writing. You leave with a folder, not a promise to email later.
