Knauf Home Energy Audit in Sunnyvale: What to Know First
A Knauf home energy audit in Sunnyvale pinpoints exactly where your house is losing conditioned air and what your Knauf insulation is actually doing about it. We perform independent Knauf home energy audits across Sunnyvale, typically completing the full diagnostic in 2 to 3 hours with a written report you can act on. Pricing is upfront, and as an independent Knauf service provider, we’re not tied to any manufacturer’s script, so you get an honest read on what’s working and what isn’t.
This page is for Sunnyvale homeowners who have Knauf insulation, suspect it’s underperforming, or want to verify it was installed correctly in the first place. If you’re ready to find out, call (669) 215-4805 and a live person answers.
How Knauf Products Fail and How We Fix Them
Knauf makes solid insulation products, but nothing lasts forever, and Sunnyvale’s climate has a way of exposing weak points. Here’s what we find on audit after audit:
- Knauf EcoBatt compression in tight bays. We see this mostly in 1970s ranch-style homes near Murphy Avenue. The original installer wedged R-19 batts into 2×4 cavities, compressing them to R-11 or worse. Our thermal imaging catches the temperature striping in the walls, and we pull a sample to confirm. Fix: pull, inspect, and reinstall at proper density or upgrade the cavity.
- Knauf Jet Stream Ultra settling in open attics. Sunnyvale’s summer heat cycles cause the blown-in fiberglass to settle, especially in attics with ridge venting. We’ve measured 10 to 14 inches that started at 16. A blower door test paired with our inspection shows the R-value drop. Fix: top off to the correct depth for the R-value you paid for.
- Knauf faced batt vapor barrier installed backward. This is a builder shortcut we find in newer townhouses off El Camino Real. The kraft facing faces the living space instead of the conditioned side. On cooler nights, moisture condenses inside the wall cavity. We catch it with a moisture meter during the insulation inspection. Fix: strip and reface, or replace the batt entirely depending on age.
- Knauf Earthwool batts chewed by roof rats. Roof rats love Sunnyvale’s older neighborhoods. They tunnel through Earthwool in attic spaces, leaving trails that wreck thermal performance. During our attic inspection we look for droppings and tunneling paths. Fix: remove contaminated material, rodent-proof penetrations, and reinstall.
- Knauf R-38 attic blanket gaps at soffit vents. Installers often block soffit vents with the blanket edge, which chokes attic ventilation and drives heat buildup. We check airflow with a smoke pencil during the audit. Fix: install baffles and reposition the blanket so ventilation works again.
Our Knauf Home Energy Audit Process
Here’s what happens when you call us for a Knauf home energy audit in Sunnyvale:
- 1
You call (669) 215-4805. A live person answers, asks about your home, and schedules the audit. No voicemail tag.
- 2
We walk the house with you. Before any equipment comes out, we ask about drafty rooms, hot spots, and your energy bills. You know your house better than we do.
- 3
Blower door and thermal imaging. We depressurize the house and scan every wall, ceiling, and floor with an infrared camera. This shows us exactly where your Knauf insulation is missing, compressed, or failing.
- 4
Targeted inspection. We access the attic and crawl space to verify what the camera suggested. If a duct leak is suspected, we run a duct leakage test. Good insulation means nothing if your ducts leak.
- 5
We sit down with you. You get a written report with photos, measurements, and priorities. We’ll tell you what needs fixing now, what can wait, and what doesn’t need touching at all.
- 6
You decide, and we do the work. If you hire us, every fix is covered by our lifetime Done Right Promise. If it’s not done right, we make it right. No fine print, no runaround.
What Knauf Home Energy Audit Costs in Sunnyvale
We charge a flat fee for the audit itself, and every quote we give includes a line-item breakdown without hidden extras. Here’s the honest price picture for Sunnyvale:
- Core Knauf home energy audit: $250 to $450, depending on home size and whether we’re testing ducts too.
- Blower door test only: $150 to $250.
- Thermal imaging inspection: $200 to $350 as a standalone service.
- Duct leakage test: $200 to $300.
- Full report with priorities and our fix estimates: included with the audit.
Your price moves based on square footage, number of stories, and whether the attic and crawl space are accessible. Sunnyvale homes with flat roofs or vaulted ceilings cost more simply because they’re harder to inspect. And by the way, estimates are free, so call (669) 215-4805 to get exact numbers for your house.

Most Sunnyvale homes take 2 to 3 hours from arrival to written report, depending on attic and crawl space access. You’ll have results the same day, not a week of waiting.
