Fast, Reliable Blown-In Insulation Across Manor
Blown-in insulation in Manor typically runs $1,200-$3,800 for most attic projects, with same-day assessments available and crews usually on-site within 24-48 hours. We dispatch to Manor from our Austin office, and we’ve spent years tracing the same failure pattern across ShadowGlen, Presidential Glen, and the other master-planned subdivisions that absorbed Austin’s overflow buyers in the 2000s and 2010s. If your home was built between 2002 and 2015, there’s a strong chance your attic has settled builder-grade blown fiberglass performing closer to R-19 than the R-30 it started with.

Why Topside Attic Insulation Pflugerville Is Manor’s Preferred Blown-In Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of our blower-door callbacks come from Manor’s early-2000s tract builds. The reason is straightforward: those subdivisions were built fast, insulated to minimum code, and left to bake on the Blackland Prairie while the fiberglass settled and the air leaks went unsealed.
Our reviews from Manor homeowners consistently mention the same two things - the written price they received before anyone touched their attic, and the before-and-after blower-door numbers that showed them exactly what changed. Under Haven Standard Clause 1, no work starts without a flat price, written scope, and written warranty in hand.
Response time to Manor is typically next-day for assessments and 24-48 hours for scheduled work. Crews know the local subdivisions, the slab-on-grade construction patterns, and the specific failure modes that show up in homes off FM 973 and US 290.
Every job closes with a Documented Photo Record, and on air-sealing work we publish before-and-after blower-door readings - a pressurization measurement that shows, in one number, how much conditioned air your home was losing before and after.
Our Blown-In Insulation Services in Manor
Blown-In Cellulose
Cellulose performs well in Manor’s extreme attic heat. We typically specify GreenFiber blown-in cellulose for top-ups over settled fiberglass in ShadowGlen-era homes, bringing assemblies back to R-38-R-49. The material handles the 150°F-plus attic temperatures on the Blackland Prairie better than degraded fiberglass, and it packs tighter around irregular framing and penetrations. We air-seal first - top plates, can lights, HVAC chases - then blow. Never the reverse.
Blown-In Fiberglass
New blown-in fiberglass has its place, particularly in new construction or full attic replacements where we’re starting with a clean, sealed deck. We source from Owens Corning, Johns Manville, and Knauf. In Manor, we rarely recommend fresh fiberglass over existing settled fiberglass without removal - the compaction layer underneath undermines the new material’s performance. When we do use fiberglass, it’s after we’ve addressed the air leakage that caused the original to fail.
Dense-Pack Wall Insulation
Manor’s post-2000 tract homes often have minimal wall insulation, especially in two-story designs with balloon framing or open chases. Dense-pack cellulose fills these cavities under pressure, reducing convection loops that carry heat through the envelope. This matters in Manor’s unshaded subdivisions, where wall solar gain is relentless from May through October. We drill and fill from exterior or interior, patch, and match texture.
Blown-In Top-Up
This is our most common service call in Manor. At a ShadowGlen home off ShadowGlen Trace, we pulled attic depth readings on a 2006 build and found the original blown fiberglass had compacted to roughly 9 inches with visible heat-shadowing around the recessed cans. After air-sealing the top plates we topped the attic up with GreenFiber blown-in cellulose to bring the assembly back to a real R-38-R-49, and the homeowner’s afternoon thermostat runs dropped noticeably that same week. Most Manor top-ups run $1,200-$2,400 for a 1,800-2,400 square foot home.

Before
AfterTrusted Brands We Service in Manor
We stock and install Rockwool, CertainTeed, and Icynene materials for Manor jobs, with no proprietary lock-in that limits your options. Rockwool’s mineral wool handles the radiant heat load on dark builder roofs in unshaded Blackland Prairie subdivisions without the degradation pattern we see in older fiberglass. CertainTeed’s blown fiberglass products work well for new-construction or full-replacement scenarios where we’re starting with a sealed attic deck. Icynene’s open-cell spray foam integrates with blown-in systems for hybrid assemblies in complex rooflines. Parts and materials are stocked locally, so we’re not waiting on freight when a Manor crew is scheduled.
Common Blown-In Insulation Problems We See in Manor Homes
- Settled builder-grade fiberglass performing at half its rated R-value. Original blown fiberglass installed at roughly R-30 in early-2000s ShadowGlen builds has compacted to an effective R-19 or lower after 15-20 Texas summers. Homeowners are often surprised - they assume a “newer” home is efficient.
- 150°F-plus attic temperatures baking what’s left. Dark builder roofing over unshaded Blackland Prairie lots, common throughout Presidential Glen and surrounding subdivisions, drives radiant heat through thin, under-sealed ceiling planes. The fiberglass that remains is thermally stressed and brittle.
- Unsealed air leaks bypassing the insulation entirely. Fast tract construction left top plates, can lights, and HVAC chases open. Blown insulation gets bypassed by air leakage before it ever performs at its rated R-value. We measure this with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing.
- Minimum-code installation that was barely adequate when new. Construction-grade insulation packages in Manor’s entry-level builds met IRC minimums at best. Those minimums have since been revised upward, and the material has degraded regardless.
Pricing for Blown-In Insulation in Manor, TX
Most blown-in attic projects in Manor fall between these ranges:

What moves the number: attic accessibility, existing insulation condition, square footage, and whether we find active air leaks that need sealing before any insulation goes in. We don’t blow insulation over an unsealed attic floor - that’s Haven Standard, not an upsell. Every estimate is free, written, and delivered before any work starts.

FAQs - Blown-In Insulation in Manor
Your 2005 build was almost certainly insulated to minimum code with cheap blown fiberglass that has compacted from roughly R-30 to an effective R-19 or lower after 15-20 summers on the Blackland Prairie. The “drive till you qualify” subdivisions east of Austin were built fast and entry-level; construction-grade insulation packages degraded faster than the materials used in custom builds from the same era. Call (737) 259-8352 and we’ll pull depth readings and a blower-door number so you can see exactly what you’re working with - estimates are free.
We can top up over existing fiberglass in most Manor attics if the material is dry, uncontaminated, and the deck underneath has been air-sealed first. We never blow new insulation over unsealed top plates, can lights, or HVAC chases - the air leakage just bypasses it. If the existing fiberglass is moisture-damaged or heavily compacted with heat shadowing, we recommend removal. We’ll tell you which category you’re in after the assessment, with photos and a written price either way.
Yes - in fact, newer tract homes in Manor often show the most dramatic improvement because they started with so little. A 2012 build in a subdivision off FM 973 with R-30 fiberglass settled to R-22 and unsealed can lights will typically see a 25-40% reduction in cooling load after proper air sealing and a cellulose top-up to R-38-R-49. The blower-door test before and after will show you the exact air-leakage reduction.
For top-ups over settled existing insulation in Manor’s extreme attic heat, we typically specify blown-in cellulose. It handles compaction and radiant heat better than fiberglass, fills irregular spaces more completely, and doesn’t degrade as visibly under sustained 150°F temperatures. Fresh blown-in fiberglass works well for new construction or full replacements with a clean, sealed deck. We’ll recommend based on what we find in your attic, not a default preference.
We verify with three things: attic depth readings at multiple points, visual inspection for compaction and heat shadowing, and a blower-door test that measures your home’s air leakage in CFM50. You get the numbers in writing before any work is proposed. If your attic is performing at spec, we’ll tell you. The assessment and written estimate are free - call (737) 259-8352 to schedule.
