Fast, Reliable Blown-In Insulation Across Manor
Blown-in insulation in Manor, TX typically runs $1.80-$3.20 per square foot installed, with most attic top-up jobs finishing same-day and full re-blows completing in one to two days. If your home is in Whisper Valley, ShadowGlen, or anywhere along FM 973, we’re the crew that shows up with a written price in hand and leaves with blower-door numbers that prove the work. Call (737) 259-7528 - a live person answers, even at 10 PM on a Sunday.
We’ve been sealing and insulating homes on the eastern edge of the Austin metro since 2016. Dispatch runs from our Austin office, but our crews live out here and know the difference between a Whisper Valley geothermal spec home and a 1970s ranch near downtown Manor. That matters when you’re deciding whether to top up settled fiberglass or tear it out and start clean.
Why Topside Attic Insulation Round Rock Is Manor’s Preferred Blown-In Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a growing share of them sit in Manor’s fast-build subdivisions. Our reviews from Manor customers consistently mention two things: the written price they received before anyone touched the attic, and the photo record and blower-door readings they walked away with. No one else in this market publishes before-and-after pressurization numbers on every applicable job.
Response time to Manor is typically same-day or next-morning. We’re on FM 973 or US 290 regularly, and we don’t schedule callback windows measured in business days. Under Haven Standard, you get a named technician and a text when they’re on the way.
What separates us in Manor specifically is our familiarity with production-builder attic packages. We know what code-minimum R-38 blown fiberglass looks like after five summers in a Blackland Prairie attic. We’ve measured the settlement. We’ve documented the compression. And we’ve seen what happens when that underperforming insulation meets a Whisper Valley geothermal heat pump that’s working harder than it was designed to.
Our Blown-In Insulation Services in Manor

Blown-In Cellulose
Cellulose is our go-to for Manor homes where the existing fiberglass has settled past recovery. We source from GreenFiber and other manufacturers, and we like it for this market because it handles the 155-160°F attic peaks better than degraded fiberglass. In Whisper Valley, we’ve used cellulose top-ups to bring settled attics back to spec without disturbing the geothermal system’s balance. The material packs tighter, fills irregular cavities better, and doesn’t lose R-value as fast under compression. Most Manor cellulose jobs run $2.20-$3.00 per square foot installed.

Blown-In Fiberglass
We install Knauf and Johns Manville blown fiberglass for new construction and full re-blows where the old material is coming out entirely. In ShadowGlen and newer Manor subdivisions, we see this specified when builders want a clean R-49 or R-60 install over a properly sealed attic floor. We never blow new fiberglass over unsealed top plates or can lights - that’s Haven Standard, non-negotiable. The air sealing happens first, then the insulation. A full fiberglass re-blow in a typical 2,400-square-foot Manor home runs $2,800-$4,500.

Dense-Pack Wall Insulation
This is the service most Manor homeowners don’t know they need until February. The mid-century homes near downtown Manor - the ones between Bloor Street and Parsons Street - were often built with empty stud bays. No insulation, no air barrier, nothing. Dense-pack cellulose or fiberglass fills those cavities under pressure, creating both thermal resistance and an air seal. We also dense-pack the kneewalls and bonus-room walls in split-levels common off FM 973. It’s technical work that requires the right hose pressure and fill knowledge; done wrong, it bulges drywall or leaves voids. Our crews have done hundreds. Expect $1,800-$3,200 for a typical dense-pack wall job in Manor.

Blown-In Top-Up
This is our highest-volume service in Manor, and for good reason. Production builders in ShadowGlen, Whisper Valley, and the subdivisions along US 290 installed code-minimum blown fiberglass that settles and compresses within 5-7 years. A top-up doesn’t remove the old material; we air-seal the attic floor first, then blow new material over the top to restore design R-value. It’s faster than a full re-blow, usually $1,400-$2,600 for a standard Manor attic, and it’s the fix we recommend when the existing fiberglass is still in reasonable shape but has lost height. We document the before-and-after depth with photos, and on applicable jobs, we run the blower door to prove the air-sealing improvement.

Trusted Brands We Service in Manor
We stock and install materials from Johns Manville, Knauf, Rockwool, and other major manufacturers - no proprietary lock-in that limits your options. For Manor customers, this means we can match existing builder-grade material when doing a targeted repair or upgrade, and we can spec higher-performance products when the job calls for it. We keep common densities and blower settings on file for the Owens Corning and Johns Manville products originally installed in ShadowGlen and Whisper Valley, which cuts our prep time and gets your crew started faster. Every bag is documented in your photo record, so you know exactly what went into your attic.
Common Blown-In Insulation Problems We See in Manor Homes

- Settled builder-grade fiberglass in Whisper Valley and ShadowGlen. The Owens Corning or Johns Manville blown fiberglass installed in most post-2010 Manor tract homes compresses to roughly six inches within 5-7 years, dropping effective R-value below R-30. Homeowners notice first through longer HVAC run times or, in Whisper Valley, a geothermal heat pump that short-cycles or runs continuously.
- Attic hatch air leakage in low-pitched Blackland Prairie roofs. Manor’s prolonged 100°F-plus summers create extreme attic temperatures that degrade insulation at the edges, but the bigger problem is often the hatch itself. Post-2010 homes frequently have unsealed, uninsulated attic hatches that leak conditioned air year-round. Winter Storm Uri exposed this weakness dramatically.
- Empty stud bays in mid-century downtown homes. The older housing stock near Manor’s historic core - homes built from the 1940s through 1970s - often has no wall insulation at all. After a hard freeze, interior walls stay cold for hours even with the heat running. Dense-pack is the fix, but it requires a crew that knows how to navigate knob-and-tube remnants and irregular framing.
- Geothermal system underperformance misdiagnosed as equipment failure. In Whisper Valley, we’ve seen multiple homeowners told their Trane geothermal heat pump needed replacement when the real issue was attic envelope leakage. The shared EcoSmart loop is designed for a tight building envelope; when blown insulation settles and air sealing fails, the system works overtime to compensate.

FAQs - Blown-In Insulation in Manor

Yes, and we’ve documented this exact pattern multiple times in Whisper Valley. When builder-installed blown fiberglass settles below R-30 effective value, the geothermal heat pump works harder to maintain setpoint, and the shared EcoSmart loop can’t compensate for envelope leakage. We were called to a Whisper Valley home off EcoSmart Loop after the homeowner’s geothermal heat pump was short-cycling through the afternoon. Our tech pulled the attic hatch and found the builder’s Owens Corning blown fiberglass had settled to roughly six inches in the center of the field, well below the R-38 spec, so we dense-packed the low corners and topped the field back to spec with GreenFiber cellulose. The pump’s run cycles dropped back to design range the same week. Call (737) 259-7528 for an energy audit with blower-door testing - estimates are free.
Measure the depth with a ruler at multiple points across the attic field - not just near the hatch. R-38 blown fiberglass should sit at roughly 12-14 inches when properly fluffed; if you’re seeing 6-8 inches in the center, the material has compressed and lost effective R-value. ShadowGlen homes built between 2012 and 2019 are particularly prone to this. We document depth with photos on every assessment and can run a blower-door test to quantify air leakage through the attic floor. Call (737) 259-7528 to schedule - estimates are free.
They do, especially in low-pitched roofs common in production subdivisions. Attic cavities in Manor regularly hit 155-160°F, which accelerates fiberglass compression and can cause thermal drift in some formulations. The bigger issue is often the air movement those temperatures drive - hot attic air pushes through gaps around can lights, top plates, and the attic hatch, making the insulation work harder than it should. Radiant barrier or closed-cell supplementation is often worth considering for Manor homes with shallow roof pitches. Call (737) 259-7528 and we’ll assess whether your roof geometry warrants it.
The attic hatch, yes - almost always. Post-2010 Manor tract homes typically have unsealed, uninsulated hatches that leak significant conditioned air. Interior walls are a separate question: if your home is in Whisper Valley or ShadowGlen and was built with standard production practices, the interior walls may already have batts or blown fill. If you’re in the older stock near downtown Manor or in a split-level off FM 973, empty stud bays are common and dense-packing them pays off in both comfort and efficiency. We can check with a thermal camera on site. Call (737) 259-7528 for an assessment - estimates are free.
A top-up leaves existing insulation in place, air-seals the attic floor, then blows new material over the top to restore design R-value. It’s faster, less expensive ($1,400-$2,600 typical in Manor), and appropriate when the old fiberglass is still in reasonable shape but has settled. A full re-blow removes all existing material first - necessary when there’s rodent contamination, water damage, or severe compression that can’t be recovered. Full re-blows run $2,800-$4,500 in Manor and give us a clean slate to seal every penetration before the new insulation goes in. We’ll tell you which makes sense after we see the attic; we don’t upsell re-blows when a top-up will do. Call (737) 259-7528 for a written recommendation - estimates are free.
