Rockwool Home Energy Audit in Pflugerville: What to Know First
We provide independent Rockwool home energy audit in Pflugerville with same-day scheduling most weekdays, and we publish your before-and-after blower-door numbers so you see the actual air-leakage change. Most Rockwool audits in the area run $280-$480 depending on home size and whether duct-blaster testing is included; we deliver a written price before anyone enters your attic, no exceptions. This page is for homeowners in Pflugerville who have Rockwool Comfortbatt, Comfortboard, or AFB (Acoustic Fire Batt) in their walls or attic and need to know whether the insulation is performing or just sitting there. Call (737) 259-8352 for a free estimate, or text us if that’s easier.
How Rockwool Products Fail - and How We Fix Them
- Comfortbatt settled below top plates in vented attics. The mineral-wool fibers don’t degrade, but gravity and Pflugerville’s 110°F summer attic heat can compress the batts over 5-7 years, leaving a gap where conditioned air escapes into the roof deck. We pull the settled batts, air-seal the top plates and electrical penetrations with fire-rated caulk and gasketed covers, then reinstall to full depth or supplement with blown-in where the cavity allows.
- Comfortboard 80 on exterior walls with improper rainscreen gaps. The rigid board needs a 3/8-inch minimum drainage plane behind it; Pflugerville’s spring storms and wind-driven rain will find a wall without one. During our audit we probe the exterior sheathing with a moisture meter and thermal camera, and if we find wet sheathing behind the Comfortboard, we document it and refer you to a siding contractor before we touch the insulation.
- AFB in interior partition walls transmitting HVAC noise. The acoustic batt is dense, but if the wall cavity isn’t fully packed or the outlets aren’t sealed with putty pads, low-frequency rumble from flex-duct runs travels straight through. We use a smoke pencil to find pressure differentials across the partition, then repack the AFB and seal electrical boxes with intumescent putty.
- Rockwool batts installed over unsealed can lights. This is the one we see most in Pflugerville’s 2005-2015 builds: the installer stuffed Comfortbatt against IC-rated housings that still leaked 15-20 CFM each. The insulation doesn’t fail, but the assembly fails. We pull the batts back, install pre-made fire-rated covers, seal with high-temp caulk, then replace the Rockwool.
- Comfortbatt in kneewalls with no blocking. In Pflugerville’s two-story homes with finished attics, kneewall batts fall out or get kicked aside by storage activity. We install rigid blocking at the kneewall base, secure the Comfortbatt with mechanical fasteners and mesh, and air-seal the floor joist bays below to stop the thermal bypass.
Our Rockwool Home Energy Audit Process

- 1
Call or text (737) 259-8352. A live person answers 24/7. We ask square footage, year built, and whether you’ve had prior insulation work. You get a 2-hour arrival window.
- 2
Blower-door test - pre-work. We depressurize the house to 50 Pascals and record the CFM50 reading. In Pflugerville’s 1,800-2,400 sq. ft. homes built 2005-2015, we typically see 3,500-5,500 CFM50 before any sealing.
- 3
Thermal imaging and physical inspection. Our tech walks the attic with a FLIR camera, marking Comfortbatt gaps, compressed areas, and thermal bridging at trusses. We photograph everything.
- 4
Written scope and price. Before any work starts, you get a flat price, a written scope, and the 365-Day Done Right Promise in writing. Haven Standard Clause 1: no surprises.
- 5
Air sealing first, then insulation correction. We seal top plates, wire penetrations, and can lights with fire-rated materials compatible with mineral wool. Then we reinstall, supplement, or replace Rockwool as needed.
- 6
Post-work blower-door test and documentation. We run the house again and hand you the pre- and post-CFM50 numbers, plus a photo record of the sealed areas. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
Before
AfterWhat Rockwool Home Energy Audit Costs in Pflugerville
| Service | Typical Range |
|---|---|
| Basic audit: blower-door + thermal imaging + insulation inspection | $280-$380 |
| Audit with duct-blaster testing (recommended for homes with flex duct in attic) | $380-$480 |
| Air sealing of top plates, penetrations, and can lights (labor + materials) | $450-$950 |
| Comfortbatt supplementation or reinstallation (per square foot of attic) | $2.80-$4.20 |
| Kneewall blocking and batt securement (per linear foot) | $18-$28 |
What moves the price: attic accessibility (scuttle vs. pull-down stairs), number of can lights, whether the Rockwool is salvageable or needs full replacement, and whether we find active roof leaks or rodent damage that must be addressed first. We also service Reflectix radiant barrier systems if your audit reveals that’s part of your assembly. Call (737) 259-8352 for an exact quote - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.
Why Pflugerville Homeowners Call Topside Attic Insulation Pflugerville for Rockwool Work

We’ve been in and out of attics along Pflugerville’s Stone Hill Town Center corridor often enough that the regional heat-load patterns aren’t a surprise to us. Wes Okafor trained in building systems technology at Kennedy-King College, where the instructors drilled air-sealing fundamentals before insulation installation - a sequence we still follow. Every Rockwool job gets before-and-after blower-door numbers, not a handshake and a promise. Our materials come from Rockwool, Owens Corning, Johns Manville, and other manufacturers - no proprietary lock-in means we specify what’s right for your assembly, not what’s in our warehouse. The 365-Day Done Right Promise applies to all completed work, and our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7.
FAQs
No. As an independent Rockwool service provider, our audit is non-destructive and does not alter the product installation in a way that affects manufacturer coverage. We document our findings with photos rather than disassembling wall assemblies unnecessarily. If we do find a warranty-eligible defect in the Rockwool itself, we flag it in our report so you can file directly with the manufacturer. Call (737) 259-8352 to schedule - estimates are free.
Most Pflugerville homeowners get same-day or next-day service. We keep blower-door equipment and thermal cameras on every truck, so we’re not waiting on a specialist crew. Emergency scheduling is available if you’re experiencing extreme temperature swings or utility bills that spiked suddenly. Text (737) 259-8352 for the next open window.
Repair is almost always cheaper, and Rockwool mineral wool doesn’t degrade chemically - it compresses, shifts, or gets installed wrong in the first place. If the batts are still dense and the fibers intact, we reposition, supplement, and air-seal around them. Full replacement only makes sense when the product has been water-compromised or contaminated. We’ll tell you which category you’re in before we quote. Call (737) 259-8352 for a free assessment.
Rockwool doesn’t make “repair parts” for insulation the way an HVAC manufacturer makes compressors. We use Rockwool batts and boards where the specification calls for them, and we use fire-rated air-sealing products - caulk, gasketed covers, intumescent putty - that are tested for compatibility with mineral wool assemblies. If your project requires a specific R-value or fire rating that only Rockwool achieves, we source it; if a comparable mineral wool from Johns Manville or another supplier meets the spec at lower cost, we present both options in writing. Call (737) 259-8352 to review.
You receive a written report with pre- and post-blower-door CFM50 readings, thermal images with annotations, a photo record of all sealed areas, and a copy of your written scope and warranty. This is standard on every job, not available on request. Under Haven Standard: Have it in writing. Call (737) 259-8352 to schedule your Rockwool home energy audit in Pflugerville.
