Knauf Home Energy Audit Nationwide

Knauf Home Energy Audit in San Marcos: What to Know First

We provide independent Knauf home energy audit in San Marcos, typically completed in 2 to 4 hours with same-day scheduling available most weekdays. A full audit runs between $350 and $650 depending on home size and test complexity, and you’ll get a written price before we start - no exceptions. This page is for homeowners who’ve found Knauf insulation, air sealing, or building envelope products in their attic, walls, or crawl space and need to know whether those materials are performing as designed. Call (737) 337-8049 to schedule or get a free second opinion on any written estimate you’ve already received.

How Knauf Products Fail - and How We Fix Them

• Knauf EcoSeal Plus gaps at top plates in older San Marcos slab homes. The water-based elastomeric sealant shrinks in our Hill Country dry spells, leaving hairline cracks at the wall-to-ceiling junction where it matters most. We pull back existing insulation, re-seal with Knauf EcoSeal Plus or transition to a compatible acrylic-latex hybrid where seasonal movement is severe, then re-test with the blower door to confirm the fix.
• Knauf Jet Stream Ultra blown-in fiberglass settling below labeled R-value in vented attics. The high-loft product loses volume when daily attic temperatures swing 40-plus degrees, which is standard from March through October in San Marcos. We measure settled depth with a ruled probe, calculate actual R-value against the labeled bags-per-square-foot spec, and add material or switch to a denser Knauf product like Insulation Plus if the assembly can’t maintain height.
• Knauf Insulation Board (rigid XPS) warping at rim joists in crawl spaces with seasonal moisture. The board edges curl when relative humidity cycles above 70 percent, common in San Marcos crawl spaces after spring rains. We remove warped sections, install a proper vapor barrier if missing, and re-cut boards to maintain full contact with the sill plate - no gaps, no compression.
• Knauf Momentum duct wrap compression from prior contractor error. We’ve found this flexible fiberglass wrap strapped so tight it crushed to half thickness, which cuts its R-value by the same proportion. We re-wrap with proper tension using Knauf-recommended fasteners or transition to a pre-formed duct sleeve where space allows, then pressure-test the duct system to prove the thermal boundary holds.
• Knauf EcoBatt with ECOSE Technology off-gassing odor in sealed attics with inadequate ventilation. The plant-based binder can release residual odor when the attic is converted to conditioned space without proper mechanical ventilation. We verify air changes per hour with the blower door, add controlled ventilation per ASHRAE 62.2, and document that the smell dissipates - we don’t mask it.

Our Knauf Home Energy Audit Process

1. 1
   Schedule and scope. Call (737) 337-8049; a live person answers. We confirm square footage, year built, and any known comfort complaints. You get a written price range by text or email before we dispatch.
2. 2
   Blower-door baseline. We run a pressurization test - a calibrated fan in an exterior door that measures, in CFM50, how much air your building envelope leaks. This number goes on your report before we touch anything.
3. 3
   Thermal imaging and physical inspection. Our FLIR camera finds Knauf insulation gaps, compression, or moisture staining invisible to the eye. We probe depth at multiple points and photograph every anomaly.
4. 4
   Duct leakage test if applicable. We pressurize the duct system to 25 Pascals and measure leakage to outside. Knauf duct wrap means nothing if the air it’s conditioning never reaches the rooms.
5. 5
   Written findings with options. You get a single page: blower-door number, thermal images with temperature readings, insulation depth map, and prioritized fixes with flat prices. No package tiers, no urgency tactics.
6. 6
   Work and verification. If you proceed, we complete the air sealing or insulation work, run the blower door again, and hand you the before-and-after sheet. The 365-Day Done Right Promise applies from that moment.

What Knauf Home Energy Audit Costs in San Marcos

Homes near the Texas State University corridor built between 1965 and 1995 often need the comprehensive tier - slab-on-grade construction with minimal original air sealing and Knauf retrofits done piecemeal by prior owners. Every estimate is free, and we’ll read any competing written quote with you line by line. Call (737) 337-8049 for yours.

Why San Marcos Homeowners Call Topside Attic Insulation San Marcos for Knauf Work

We’re an independent Knauf service provider - no factory affiliation, no product lock-in. That means when Knauf EcoSeal Plus isn’t the right choice for your home’s movement patterns, we’ll say so and specify what is. Wes Okafor and our crew have sealed and insulated over 9,000 homes since 2016, and we publish before-and-after blower-door numbers on every job where air sealing is performed. The R-value tells you how slow heat moves through the material - the blower-door number tells you whether any of that matters.

We also work with Reflectix and every major insulation brand, so if your audit reveals a material mismatch (Knauf batts where spray foam should be, for example), we can quote the correct fix without a second contractor. Calls are answered live 24/7. Technicians are background-checked, uniformed, and named - you’ll get a text when yours is en route. Under Haven Standard: Have it in writing, always.
