Knauf Home Energy Audit in Campbell: What to Know First
We provide independent Knauf home energy audit services in Campbell, typically completing the full diagnostic visit in 2 to 3 hours with written findings delivered same-day. Most audits run between $350 and $650 depending on home size and the number of HVAC zones we need to test. We do not start any work without a written price, and we do not sell insulation to homeowners whose air leaks haven’t been quantified first.
This page is for Campbell homeowners who have Knauf insulation or insulation accessories in their attic, walls, or crawl space and need to know whether the product is performing as specified. You might have Knauf EcoSeal, Knauf Jet Stream, or Knauf Insulation Board in a 1960s ranch near Campbell Avenue or a newer build off Winchester Boulevard. Wherever you are in Campbell, call us at (831) 534-3206 for a free estimate.
How Knauf Products Fail - and How We Fix Them
- Knauf EcoSeal gaps at top plates in older Campbell framing. EcoSeal is a water-based elastomeric sealant designed to air-seal the attic floor, but in Campbell’s pre-1980 stick-framed homes with irregular stud bays, the product can bridge rather than fill, leaving thermal bypasses at the wall-to-ceiling junction. We remove failed EcoSeal where it has shrunk or delaminated, then reseal with compatible acrylic-latex or transition to Knauf’s recommended two-part foam at complex intersections.
- Knauf Jet Stream settled density in long attic runs. Jet Stream blown-in fiberglass is specified for a minimum settled density of 0.5 pcf, but we regularly find Campbell installations at 0.3 to 0.4 pcf where the installer rushed the hose work or used incorrect fan settings. The result is visible battens and cold spots on thermal imaging. We probe-density test during audit, flag underfilled zones, and redeploy to specification using Knauf’s published coverage charts.
- Knauf Insulation Board compression at pull-down attic stairs. Rigid board products like Knauf’s Thermafiber or EcoBatt boards get compressed by homeowners storing holiday decorations on them, crushing fiber structure and dropping effective R-value by 30 to 50 percent. We document compression depth, calculate the thermal penalty, and recommend either board replacement or a protected storage platform that preserves the insulation envelope.
- Knauf vapor barrier misalignment in crawl spaces. Knauf crawl space products rely on proper poly placement to manage Campbell’s winter soil moisture drive. We find vapor barriers tucked behind rather than sealed to piers, or terminated at the foundation wall without mechanical fastening. Our fix: full reinstallation with 6-mil minimum poly, sealed seams, and pier wrapping per ASTM E1643.
- Knauf accessory tape failure at duct board connections. Knauf FSK tape (foil-scrim-kraft) on duct board systems degrades in Campbell’s attic heat cycles, losing adhesion at the 7- to 10-year mark. We thermal-image duct runs to locate tape failures, then reseal with Knauf-compatible FSK or upgrade to mastic plus fiberglass mesh for a longer service interval.
Our Knauf Home Energy Audit Process

- 1
Call and scheduling. A live person answers, confirms your Knauf product type if known, and books a 2- to 3-hour window. You get a text when your technician is en route.
- 2
Blower-door test - baseline. We depressurize the house to 50 Pascals and record the CFM50 reading, the single number that tells us how leaky the envelope is before we touch anything.
- 3
Thermal imaging and insulation inspection. Our tech walks the attic, walls, and crawl with a FLIR camera, cross-referencing against the Knauf product spec sheet for that installation year. We look for settlement gaps, compression, moisture staining, and thermal bridging.
- 4
Duct leakage test if applicable. We pressurize the duct system and measure leakage to outside, since Knauf-insulated attics with leaky ducts lose efficiency twice: once through the duct, once because the attic is vented.
- 5
Written findings and price. You get a printed report with the before blower-door number, thermal images with annotations, and a flat price for any recommended work. No work starts without your signature on that price.
- 6
Post-work verification. On jobs where we perform air sealing or insulation correction, we run the blower door again and hand you the after number. Seal the leaks first. The insulation has nowhere useful to go until you do.

What moves the price: home square footage, number of attic access points, whether we need to move stored belongings to inspect, and the age of the Knauf installation (older products may require more extensive probing). We also service Reflectix radiant barrier systems, which we evaluate alongside Knauf products in mixed-insulation attics.
Call (831) 534-3206 for a free estimate. We’ll read any competing written estimate with you - our Free Second Opinion - and give you a flat price before any work starts, always.
Why Campbell Homeowners Call Topside Attic Insulation Campbell for Knauf Work

We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve sealed and insulated more than 9,000 homes since then. Every one started with a written price and ended with a documented record. Wes Okafor, our owner and lead technician, learned the trade at Olive-Harvey College in Chicago and spent the better part of two decades in South Bay attics before settling the crew in Campbell. Jobs near the Pruneyard Plaza corridor taught him that homes this age carry air-sealing problems - top plate gaps, can light bypasses, chimney chases - that show up long before you touch a bag of blown-in cellulose.
We publish before-and-after blower-door numbers on every applicable job. You get the CFM50 before, the CFM50 after, and the photos to match. Our 365-Day Done Right Promise means if it’s not done right, we make it right. And we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, so we specify what actually fits your assembly.
FAQs
No. As an independent Knauf service provider, our diagnostic work does not affect Knauf’s limited product warranty, which covers manufacturing defects, not installation or in-service conditions. We document our findings so you have evidence if a material defect claim is warranted. Call (831) 534-3206 and we’ll explain what is and isn’t covered on your specific Knauf line.
We typically schedule within 2 to 4 business days, and emergency scheduling is available for homes with active moisture intrusion or HVAC failure. Same-day written findings are standard. Call (831) 534-3206 to check this week’s availability.
Repair is cost-effective when the Knauf product is less than 15 years old, properly installed, and only locally compromised - settlement in one attic zone, compression at a storage area, tape failure at duct connections. Replacement makes sense when the product is beyond its service life, extensively water-damaged, or installed at insufficient density throughout. We give you both prices in writing so you can decide. Estimates are free.
We carry common Knauf-compatible air-sealing materials, FSK tape, and touch-up blown-in fiberglass on our trucks. Specialty board products or discontinued Knauf lines may require a 3- to 5-day order, which we disclose in the written price before you commit. You’ll never start a job with us and learn mid-project that we’re waiting on parts.
You get a printed report with the blower-door CFM50 reading, annotated thermal images, insulation density probe measurements where applicable, a written scope of recommended work with a flat price, and our warranty terms. If we perform work, you also get the after blower-door number and a Documented Photo Record of the completed assembly. Under Haven Standard: Have it in writing.
