Why Topside Attic Insulation Canyon Lake Is Cibolo’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a growing share of them are in Cibolo’s newer subdivisions where homeowners are discovering their builder’s minimum insulation doesn’t match their actual cooling bills. Our Cibolo customers leave reviews mentioning the same thing: we show up with a written scope, we explain the blower-door numbers in plain language, and we leave documentation they can file with CPS Energy or their home warranty company.
Response time to Cibolo averages same-day or next-day because our San Antonio office dispatches crews directly to the FM 78 corridor and the Schertz-Cibolo line. We don’t ask you to wait through a callback window. A live person answers the phone 24/7, and you’ll get a text when your technician is en route with a name and photo.
Local knowledge matters here. We know which Cibolo builders used baffles in the 2010s and which skipped them. We know where the attic access is likely hidden in a two-story Richmond American floor plan versus a Perry Homes layout. That familiarity saves time and prevents the “exploratory” charges you get from out-of-market crews who treat every attic like a mystery.
Our Attic Insulation Services in Cibolo
Blown-In Attic Insulation
Blown-in fiberglass or cellulose is the standard fix for Cibolo’s settled builder-grade attics. We use Johns Manville and Knauf materials, installed with a depth gauge so you can verify the R-value from the attic hatch. In Cibolo’s two-story homes, we typically see original blown fiberglass compressed to 4-6 inches, well below current IECC targets for South-Central Texas. Our crews air-seal first, then blow to the specified depth, and we publish before-and-after blower-door numbers so you can see the actual air-leakage reduction.
Attic Batt Insulation
Batt insulation has a place in Cibolo homes, mostly for knee walls, storage platforms, or finished attic spaces where loose fill won’t stay put. We stock Rockwool and CertainTeed batts for these applications. In master-planned subdivisions like Cibolo Valley, we’ve found that bonus rooms over garages often have batts stuffed sideways into kneewalls with no air barrier, which is worse than no insulation at all. We remove those mistakes and install properly cut, faced or unfaced batts with sealed edges.
Attic Insulation Top-Up
This is our most common Cibolo service. The existing blown fiberglass isn’t removed; we air-seal the top plates, can lights, and duct penetrations, then blow new material on top to reach the target depth. For a typical 2,400-square-foot Cibolo two-story, a top-up with air sealing runs $2,200-$3,800. The homeowner gets a written scope beforehand, a Documented Photo Record afterward, and blower-door numbers if the job qualifies. Under our 365-Day Done Right Promise, if the upstairs doesn’t track closer to the first floor, we return and diagnose.
Attic Insulation Replacement
Replacement makes sense when insulation is contaminated, water-damaged, or so poorly installed that topping it up would compound the problem. In Cibolo’s post-2000 homes, we rarely see contamination, but we do see attics where the original installer blew fiberglass directly over unsealed recessed can lights or left massive gaps around HVAC platforms. We remove the compromised material, seal the envelope properly, and reinstall. Full replacement in Cibolo typically runs $3,200-$5,500 for a two-story home.
Attic Baffles & Ventilation Prep
Missing or crushed baffles are epidemic in Cibolo production-built homes. These styrofoam or cardboard channels keep soffit vents open so outside air can flow under the roof deck and flush heat out. Without them, your attic becomes a convection oven and your upstairs bedrooms pay the price. We install proper baffles at every eave before adding insulation, and we verify soffit intake isn’t blocked by the new material. This step alone often drops upper-floor temperatures 4-6°F in Cibolo’s West- and South-facing homes.

AfterTrusted Brands We Service in Cibolo
We source insulation materials from Owens Corning, Johns Manville, Knauf, Rockwool, and CertainTeed, with no proprietary lock-in that limits your options. For Cibolo homeowners, this means we match the material to the application rather than forcing a one-product solution. Blown fiberglass from Johns Manville works well for standard attic floors. Rockwool batts handle the fire-rated knee walls common in Cibolo’s two-story plans. We stock locally and coordinate delivery to avoid the delays that push other contractors’ schedules into weeks.
Common Attic Insulation Problems We See in Cibolo Homes
- Settled builder-grade blown fiberglass. In Cibolo’s 2005-2020 tract homes, original attic insulation was installed to minimum code and has since compressed to 4-6 inches, sometimes less. The R-value drops proportionally, and 150°F attic heat radiates through the ceiling all afternoon.
- Missing or crushed baffles choking ventilation. Production builders in subdivisions like Steele Creek often skipped baffles or used flimsy cardboard that collapsed under the first blown-in pass. The attic can’t exhale heat, and the upper floor stays 8-12°F hotter than the first.
- Unsealed top plates and duct penetrations bypassing insulation. Even where insulation depth looks adequate, air leaks at the wall top plates, around furnace platforms, and through recessed can lights carry conditioned air straight into the attic. We find this in roughly 80% of Cibolo homes built 2010-2018.
- Flex duct lying on insulation, unsealed at boots. Cibolo’s two-story plans run duct through attic space to reach the upper floor. Builder-grade flex duct with untaped connections leaks cooled air into the attic before it ever reaches the vent, a problem invisible from below.

FAQs - Attic Insulation in Cibolo
Your 2012 home was insulated to the 2009 or 2012 energy code minimum, not current standards, and builder-grade blown fiberglass settles significantly within 5-10 years. In Cibolo’s climate, that settled layer lets 150°F attic heat press straight through your ceiling all summer, which is why your upstairs runs hot and your CPS Energy bill keeps climbing. Call (737) 227-6219 for a free estimate - we’ll measure what you actually have and show you the numbers.
This is the single most common complaint we hear in Cibolo’s two-story subdivisions, and it almost always traces to builder-minimum attic insulation combined with missing baffles and unsealed top plates. The attic overheats, can’t ventilate, and radiates down through the ceiling of your upper floor. We recently worked a two-story home in Cibolo Valley where the upstairs game room was hitting 82°F while the downstairs thermostat read 73°F; the attic had settled builder-grade blown fiberglass at about 6 inches with no baffles, so we air-sealed the top plates, installed Owens Corning blown-in insulation to bring the R-value up, and the upstairs finally tracked within a couple degrees of the first floor.
Not usually. In Cibolo’s post-2000 homes, the existing blown fiberglass is typically clean but compressed, so we air-seal over it and blow new material on top. We only remove insulation if it’s contaminated, water-damaged, or so poorly placed that adding more would trap moisture or cover unsealed leaks. Your technician will photograph the attic and show you the condition before recommending either approach.
Yes. CPS Energy cooling bills dominate household budgets in South-Central Texas, and attic heat gain is the largest single load on your air conditioner. Proper air sealing and insulation to current IECC levels typically reduces cooling runtime 15-30% in Cibolo’s two-story homes, with payback periods of 3-6 years depending on current insulation condition and electricity rates. We document the before-and-after blower-door reading so you have proof of the improvement, not just a promise.
It does. The February 2021 freeze exposed how builder-spec insulation levels in Cibolo’s tract homes left pipes and mechanical systems dangerously vulnerable. A properly sealed and insulated attic slows heat loss through the ceiling, keeps conditioned air inside longer if power fails, and reduces the risk of pipe freezes in upstairs walls. It’s not a guarantee against a Uri-level event, but it’s a meaningful layer of protection that most Cibolo homes currently lack. Call (737) 227-6219 and we’ll assess your specific exposure.
