Fast, Reliable Attic Insulation Across Manor
Most attic insulation jobs in Manor run $1,800-$4,500 depending on whether we’re topping up existing material or stripping and replacing a failed builder-grade installation. We dispatch crews to Manor daily from our Austin office, and we can usually get a technician out for a written estimate within 24-48 hours. Call (737) 337-8049 to schedule - estimates are free, and every job starts with a flat written price before anyone touches your attic.
We’ve worked in enough homes off Pickle Parkway and out toward Lockwood Acres to know what we’ll find before we pull the hatch. Manor’s housing stock is almost entirely post-2000 construction, and the builders cut the same corners over and over. That repetition works in your favor - we can scope and quote faster here than almost anywhere else in the metro.
Why Topside Attic Insulation San Marcos Is Manor’s Preferred Attic Insulation Company
Our Attic Insulation team has sealed and insulated thousands of homes since 2016, and a growing share of that work is in Manor’s newer subdivisions. Homeowners in Kingsbery Park and the Presidential Glen area leave reviews that mention the same things: we showed up on time, we named the price before we started, and we left blower-door numbers that proved the work.
We answer calls 24/7 with a live person - no voicemail loops, no “we’ll call you back Tuesday.” For Manor, that means same-day or next-day scheduling on most non-emergency jobs, and we text you when your technician is en route with a name and photo. Dispatch runs from our Austin office, but our crews live and work throughout the eastern metro, so you’re not waiting for someone to drive in from Round Rock or San Marcos.
The documentation matters to Manor homeowners, and we get that. Every job closes with a Documented Photo Record, and on air-sealing jobs 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 the work. Under Haven Standard Clause 1, you get a written scope, a flat price, and a written warranty before anyone lifts a tool.
Our Attic Insulation Services in Manor

Blown-In Attic Insulation
Blown-in fiberglass or cellulose is what we install most often in Manor, and for good reason. The post-2000 tract homes off Manor Expressway and East Parmer Lane were originally insulated with blown fiberglass to R-19 or R-22, and that material settles and compresses within a decade - sometimes dropping to effective R-11 or lower. We air-seal first, then blow new material to modern depth, typically R-38 to R-49 for this climate zone. Most blown-in jobs in Manor run $2,200-$3,800 for a typical 1,800-2,400 square foot home.

Attic Batt Insulation
Batt insulation - pre-cut fiberglass or mineral wool panels - makes sense in Manor when we’re working in attics with limited access, doing partial repairs, or insulating knee walls and odd framing bays. We use Knauf and Johns Manville batts cut to fit, not stuffed and compressed. In the identical DR Horton-era floor plans around Presidential Meadows, we often find thin or missing batts at the eave edges where the original crew rushed the job. Replacing those with properly fitted R-30 or R-38 batts, combined with baffles for ventilation, closes thermal bypasses that undermine the whole attic assembly.

Attic Insulation Top-Up
A top-up is the most common call we get in Manor, and it’s usually the right first move. If your original blown fiberglass has settled but hasn’t been disturbed by rodents or water damage, we can air-seal the ceiling plane and blow new material on top to reach code-current depth. This saves the cost and mess of full removal. Top-up jobs in Manor typically run $1,800-$2,800. We always pull a test patch first to verify the existing material is clean and dry - no point in burying a problem.

Attic Insulation Replacement
Full replacement becomes necessary when the original material is contaminated, water-damaged, or so poorly installed that topping up won’t fix the thermal bypasses. In Manor’s slab-on-grade homes near Lockwood Farms, we’ve found attics where the builder-grade insulation was installed before the drywall was fully cured, trapping moisture and compressing the fiberglass against the ceiling. Replacement means removal, disposal, air sealing, and fresh install - typically $3,200-$4,500 for a standard Manor home. You walk away with a clean attic, a sealed envelope, and photo documentation of every step.

Attic Baffles & Ventilation Prep
Every insulation job in Manor needs proper ventilation prep, or we’re just trapping heat and moisture. We install baffles - cardboard or foam channels - at every eave vent to keep the insulation from blocking airflow and to prevent wind-washing that strips heat from the material. In Manor’s 150°F summer attics, inadequate ventilation destroys insulation performance in a matter of seasons. Baffles and ventilation prep are included on every full job and run $400-$700 as a standalone service.

Common Attic Insulation Problems We See in Manor Homes

- Settled blown fiberglass dropping below labeled R-value. The builder-grade R-19 or R-22 installed in Presidential Glen and Bella Vista at Cottonwood Creek homes has compressed to R-11 or lower within 8-12 years. You paid for a thermal barrier; you got a thin blanket that barely slows heat transfer.
- Zero air sealing at can lights and top plates. The same can-light grid punches through the ceiling in house after house across Manor’s DR Horton-era subdivisions. Without sealing those penetrations, hot attic air pours into your living space all summer, and cold air infiltrates during freeze events like the 2021 Winter Storm Uri.
- Thin or missing insulation at eave edges and attic hatches. We see this in nearly identical locations across Presidential Meadows - a 6-inch gap at the eave where the original batt was cut short, or a hatch with no gasket and a half-inch gap around the perimeter. These thermal bypasses make the rest of your attic insulation far less effective.
- Attic temperatures exceeding 150°F with no radiant barrier or adequate ventilation. Manor sits on the open Blackland Prairie with minimal tree cover. Without proper ventilation prep and sufficient insulation depth, your ductwork cooks in the attic and your AC runs overtime trying to push cool air through 140-degree supply lines.

Our crew was called to a home in Bella Vista at Cottonwood Creek where the homeowner complained of uneven cooling and high summer electric bills despite a relatively new HVAC system. When we pulled the attic hatch, we found the original blown fiberglass had settled to barely R-11 in places, with visible gaps around the can-light grid and no air sealing at the top plates - classic builder-grade shortcuts that were legal at permit time but hopelessly inadequate for Manor’s 150°F attic temps. We air-sealed the ceiling plane, baffled the eave edges for ventilation, and topped the attic off with Owens Corning blown-in insulation to bring it up to a modern R-value, and the homeowner reported noticeably more even temperatures and lower runtime on the AC within the first billing cycle.

FAQs - Attic Insulation in Manor

Because builder-grade blown fiberglass settles and compresses within 8-12 years, often dropping from its labeled R-19 or R-22 to an effective R-11 or lower. In Manor’s rapid-build subdivisions like Presidential Glen and Presidential Meadows, the original insulation was installed to code-minimum standards that have since been surpassed, with little or no air sealing. The 2021 freeze and subsequent summers have exposed how inadequate those assemblies are. Call (737) 337-8049 for a free estimate - we’ll pull a test patch and show you what you’re actually working with.
The repetition of identical DR Horton-era floor plans means we see the same three problems in nearly every home: settled blown fiberglass below labeled R-value, unsealed can-light grids and top plates, and thin or missing batt insulation at the eave edges. These were legal at permit time but create thermal bypasses that make your AC run constantly and your upstairs rooms uncomfortably hot. The upside is that familiarity lets us scope and quote these jobs faster than almost anywhere else in the metro.
Manor’s location on the open Blackland Prairie east of Austin means full sun exposure, flat terrain, and minimal tree canopy that push attic temperatures well above 150°F in summer - among the most extreme in the metro. That makes air sealing the ceiling plane and achieving adequate insulation depth (R-38 to R-49) the highest-ROI improvement you can make. The 2021 Winter Storm Uri also demonstrated how poorly these code-minimum assemblies perform during freeze events, so we prioritize sealing against cold-side infiltration as well.
Yes, in most Manor homes a top-up is the right first step - provided the existing material is clean, dry, and undisturbed. We air-seal the ceiling plane first, install baffles at the eaves, then blow new Owens Corning or Knauf fiberglass on top to reach modern depth. This avoids the cost and mess of removal. If we find moisture damage, rodent activity, or compression so severe that the original material is useless, we’ll recommend full replacement and explain why in the written scope.
We carry Owens Corning, Knauf, and Rockwool on every Manor truck, and we can source Johns Manville, CertainTeed, or other major brands on request. No proprietary products, no brand lock-in. We choose the material based on your attic conditions, your preferences, and what’s appropriate for Climate Zone 2 - and we leave the packaging with you if you want to verify R-value and manufacturing date.
