Rockwool Home Energy Audit in Pomona: What to Know First

A Rockwool home energy audit in Pomona typically costs between $300 and $650 for a full diagnostic package, and most audits are completed in under three hours with a written report delivered within 48 hours. We’re an independent Rockwool service provider, which means we work on Rockwool-insulated homes without being tied to manufacturer pricing or protocols. This page is for Pomona homeowners who already have Rockwool insulation in their attics, walls, or crawl spaces and want to know if it’s actually doing its job.

Key Takeaways

• Rockwool’s stone wool holds its R-value in Pomona’s dry heat, but installation gaps and compression are common failure points we find during audits.
• Our audits include blower door testing, thermal imaging, and duct leakage measurement, not just a visual check.
• Most audit-related repairs and air sealing get done in a single visit.
• Every audit is backed by our 90-Day Done Right Promise.

How Rockwool Products Fail, and How We Fix Them

Rockwool stone wool is a stubborn material. It resists moisture, won’t burn, and holds its shape better than fiberglass. But “better” doesn’t mean “can’t fail.” Here’s what we regularly find in Pomona homes during audits, and what we do about it.

• ComfortBatt compression in attics. Rockwool ComfortBatt is designed to friction-fit between studs, but when installers force a 5.5-inch batt into a 3.5-inch cavity or stuff batts around electrical boxes, the compressed wool loses R-value fast. During an audit, we pull back a section and check. If we find compression, we fluff and refit, or replace the batt. Simple fix, real energy savings.
• Safe’n’Sound used as thermal insulation. Safe’n’Sound is Rockwool’s acoustic line, and it’s not rated for thermal performance. We see it in Pomona homes where a previous contractor thought “insulation is insulation.” Our thermal imaging catches this immediately because the wall cavities read cooler in summer than they should. We swap it for appropriate ComfortBatt or recommend a blown-in retrofit.
• Gaps at top plates and rim joists. Rockwool batts leave a seam at the top plate where conditioned air escapes into the attic. In older Pomona bungalows near Ganesha Park, we regularly find a 1/4-inch gap along the entire top plate that adds up to the equivalent of an open window. We air seal those gaps with foam before resetting the batts.
• Rockwool board in cathedral ceilings without venting. Rockboard 80 and ComfortBoard 80 are great rigid products, but in Pomona’s older homes, installers sometimes packed them tight against the roof deck in cathedral ceilings with zero ventilation channel. Trapped heat in August pushes roof deck temperatures past 160 degrees, and the Rockwool can’t save you from that. We correct the venting or install baffles during a follow-up visit.
• Rodent tunneling in crawl space batts. Rockwool repels rodents better than fiberglass, but determined rats in Pomona’s older crawl spaces still burrow through ComfortBatt over time. During an audit, we inspect the crawl space and flag any tunneling, then quote removal and replace with fresh batts plus exclusion work.

Our Rockwool Home Energy Audit Process

Here’s exactly what happens when you call us for a Rockwool home energy audit in Pomona.

1. 1
   Phone intake. You call (626) 341-0830. A live person answers, asks about your home’s age, square footage, and what’s bugging you: high bills, hot rooms, drafts. We schedule within a few days.
2. 2
   Walkthrough and visual inspection. Our tech arrives in a uniform, background-checked. We inspect every accessible Rockwool surface: attic, crawl space, exterior walls if any cavities are open. We photograph what we find.
3. 3
   Blower door test. We mount the fan in an exterior door frame and depressurize the house. This measures total air leakage in CFM50. Pomona homes built before 1980 often run 2,000 to 4,000 CFM50. A tight home runs under 1,200.
4. 4
   Thermal imaging and duct leakage test. Infrared picks up missing or compressed Rockwool, hot wall cavities, and duct leaks. We run a duct blaster test on forced-air systems, which tells us how much conditioned air is leaking into the attic or crawl space before it ever reaches your vents.
5. 5
   Report and repair plan. You get a written report with photos and a ranked list of fixes. If air sealing or insulation repair is straightforward, most jobs are completed in a single visit. Everything we do is backed by the 90-Day Done Right Promise.

What Rockwool Home Energy Audit Costs in Pomona

Here’s what Pomona homeowners can expect to pay, based on the audits we’ve run across the city.

• Visual audit only (no blower door): $150 to $250. Good for checking Rockwool installation quality, not for measuring air leakage.
• Blower door test plus thermal imaging: $300 to $450. This is the diagnostic core and what we recommend for most Rockwool homes.
• Full audit package (blower door, thermal, duct leakage, written report): $450 to $650 depending on square footage and crawl space access. Larger homes or multi-story properties push toward the top end.
• Air sealing add-on after audit: $250 to $800 depending on the linear feet of gaps we need to close.

What moves the price: home size, number of systems (HVAC zones), crawl space access difficulty, and whether you want the duct test included. Estimates are free. Call (626) 341-0830 and we’ll give you a firm number before we step foot in the house.
