Rockwool Home Energy Audit Nationwide

Rockwool Home Energy Audit in Schertz: What to Know First

We provide independent Rockwool home energy audit in Schertz, typically completed in 90 minutes to two hours, with a written price delivered before any work starts. Most audits run between $280 and $450 depending on home size and test complexity. We’re not affiliated with or authorized by Rockwool - we work on their products as an independent service provider, which means we diagnose what’s actually failing without a manufacturer’s script to follow.

This page is for Schertz homeowners who’ve installed Rockwool ComfortBatt, ComfortBoard, or AFB (Acoustical Fire Batt) and need to know whether their envelope is performing as designed. If your utility bills climbed after installation, or if rooms over the garage in the Sedona subdivision still run ten degrees off the thermostat, the batt may be fine and the air sealing may be the problem. Call (830) 402-5240 to schedule. Estimates are free.

How Rockwool Products Fail - and How We Fix Them

• ComfortBatt settled below top plates in vented attics. Rockwool’s stone wool doesn’t degrade like fiberglass, but it can shift during high-wind events common to the Schertz corridor in spring. We find batts slid off plate lines, leaving a two-inch thermal bypass. We reposition, then seal the plate with fire-rated caulk before reinstalling.
• ComfortBoard compressed by subsequent trades. Used for exterior insulation or basement rim joists, this rigid board gets stepped on or over-tightened by HVAC crews running line sets. Compression kills the advertised R-value. We gauge actual thickness with a depth stick, replace crushed sections, and photo-document for your record.
• AFB installed without addressing cavity air leakage first. Acoustical Fire Batt is dense and performs well for sound and fire, but it’s not an air barrier. In Schertz’s cooling-dominated climate, hot attic air migrates around AFB in partition walls, making the room feel warm despite the batt being intact. We blower-door test first, seal cavities with targeted foam, then verify.
• Rockwool batts gapped around irregular framing. Stone wool cuts cleanly, but older Schertz homes - especially pre-2000 builds near FM 78 - have irregular stud bays and bracing. Gaps at the edges let conditioned air escape. We custom-cut infill pieces and spot-seal with acoustic sealant rather than jamming oversized batts.
• Retrofit jobs where Rockwool was added over existing fiberglass without air sealing. This is the most common issue we see. The homeowner gets the R-value they paid for on paper, but the stack effect pulls air through the old layer, around electrical boxes, and out the ridge vent. We remove or work around, seal every penetration, then reinstall in the correct sequence. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.

Our Rockwool Home Energy Audit Process

1. 1
   Schedule and scope. A live person answers when you call (830) 402-5240. We confirm square footage, year built, and whether Rockwool was original or retrofit. You get a two-hour arrival window and a text when the technician is en route.
2. 2
   Blower-door test. We depressurize the house to -50 Pascals and measure CFM50 - the total air leakage in cubic feet per minute. This gives us a baseline number that every subsequent decision refers back to.
3. 3
   Thermal imaging and physical inspection. Our FLIR camera finds bypasses the blower door confirms: top plates, recessed can lights, duct boots, and chimney chases. We also check Rockwool depth and placement with a probe and depth stick.
4. 4
   Written findings and price. Before any repair work, you receive a printed scope with line-item pricing, the blower-door number we measured, and the target number we expect after sealing. No work starts without your written approval - Haven Standard Clause 1.
5. 5
   Air sealing and insulation correction. We seal what we found, correct Rockwool installation issues, and add material only where the existing coverage is insufficient. OEM Rockwool or quality equivalent per your preference.
6. 6
   Post-test and documentation. We run the blower door again and print the before-and-after comparison. You walk away with the readings, thermal images, and a depth-stick photo log. Every job.

What Rockwool Home Energy Audit Costs in Schertz

What moves the price: home size, attic accessibility, whether we need to move stored items, and how much air sealing is required before insulation performs as rated. A 1,800-square-foot ranch with a clear attic and minor sealing needs sits at the lower end. A two-story with multiple HVAC zones, a finished bonus room, and blown-in Rockwool over unsealed top plates runs higher.

We also provide a Free Second Opinion on any written estimate you’ve already received - bring us another contractor’s scope and we’ll review it with you, line by line. Call (830) 402-5240 for an exact quote. Estimates are free.

Why Schertz Homeowners Call Topside Attic Insulation Schertz for Rockwool Work

We’ve been working the Schertz corridor for several years now, including jobs in the Sedona subdivision off FM 1518 where summer attic temps regularly push past 140°F before a single batt goes in. Wes Okafor built this operation on sequencing the work correctly: blower-door test first, air sealing second, insulation third. Our 365-Day Done Right Promise applies to every completed job, and we publish before-and-after blower-door numbers so you can verify the result yourself.

We’re not locked into one brand. We source Rockwool, Owens Corning, Johns Manville, Knauf, and others - including Reflectix for radiant barrier applications where that makes more sense than additional batt insulation. Background-checked, uniformed technicians. Calls answered by a live person, 24/7. Written price before any work starts, always.
