Fast, Reliable Spray Foam Insulation Across Manor
Spray foam insulation in Manor typically costs $2.80-$6.50 per square foot depending on cell type and access, with most whole-attic jobs running $3,200-$7,800 and rim joist or garage ceiling work starting around $1,400. We’re usually on-site in Manor within 24-48 hours of your call, and dispatch routes from our Austin office so crews don’t waste half a morning in I-35 traffic getting to ShadowGlen, Presidential Meadows, or the newer builds off FM 973. Call (737) 259-8352 for a written price before any work starts - that’s Haven Standard Clause 1, no exceptions.
We’ve been sealing and insulating homes under The Haven Standard since 2016, and Manor’s housing stock is unlike anything else in the metro. Almost every subdivision here went up after 2000, built fast and cheap to absorb Austin’s overflow buyers. The blown fiberglass your builder installed to minimum code has had 10-20 summers on the Blackland Prairie to settle, compact, and fail. We see it weekly. Our Spray Foam Insulation team treats air sealing as a hard prerequisite, not an upsell, and we publish before-and-after blower-door numbers on every job so you can verify what you paid for.
Why Topside Attic Insulation Pflugerville Is Manor’s Preferred Spray Foam Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a growing share of them sit in Manor’s post-2000 subdivisions. Homeowners here find us the same way they find any contractor worth hiring: they read the three-star reviews as carefully as the five-star ones, they want the price on the page, and they expect documentation they can hold in their hands. We deliver all three. Every job starts with a written scope, written warranty, and flat price before anyone lifts a tool.
Response time to Manor runs 24-48 hours for standard appointments, and our Austin office coordinates dispatch so crews hit ShadowGlen, Presidential Meadows, or the FM 973 corridor without the scheduling delays that plague contractors routing from Round Rock or farther north. Calls are answered by a live person, 24/7. No voicemail loops. No callback windows measured in business days.
Our local knowledge is specific and earned. We know which Manor subdivisions used the thinnest blown fiberglass batches in the 2005-2012 boom years. We know how the Blackland Prairie’s flat, treeless exposure pushes attic temperatures past 150°F on dark builder roofs from May through October. And we know that most Manor homeowners assume their “newer” home is efficient until they see the blower-door reading and the compacted fiberglass we’re pulling out. That combination - documented evidence, local pattern recognition, and no work without a written price - is why Manor homeowners call us back for second properties and refer us to neighbors.
Our Spray Foam Insulation Services in Manor

Closed-Cell Spray Foam
Closed-cell spray foam in Manor runs $4.50-$6.50 per board foot installed, with a typical 2-inch application on rim joists or band areas costing $1,800-$3,200 for a standard slab-on-grade home. At 2 lbs per cubic foot and R-6.5 per inch, it’s our go-to for Manor’s unvented attic conversions and any application where the foam must double as an air barrier and vapor retarder. We use closed-cell on attic-side HVAC plenums, duct boots, and top plates in ShadowGlen and similar subdivisions because it seals while it insulates - critical when your conditioned air is leaking straight into 150°F attic space. Every closed-cell job gets a blower-door test before and after, with the numbers published in your documented record.

Open-Cell Spray Foam
Open-cell spray foam in Manor costs $2.80-$4.20 per board foot installed, making it the economical choice for large attic floor or roof deck applications where 5.5-6.5 inches can achieve R-38 in a single pass. But here’s the local caveat: open-cell on an exposed roof deck in Manor’s Blackland Prairie heat can off-gas and underperform if the assembly isn’t designed for that radiant load. We specify open-cell only where the roof deck has adequate radiant barrier coverage or where we’re converting a vented attic to unvented with proper design. We don’t spray and hope. Our crew will tell you exactly which assembly your roof type supports, and we’ll put that in writing before the rig shows up.

Rim Joist Spray Foam
Because almost every Manor subdivision was built post-2000 on slab-on-grade, there are no basements and rarely usable crawlspaces - so rim joist spray foam here runs along the top plate and band in the attic, not a basement box, and unvented attic conversions are the norm rather than the exception. We also pull original blown fiberglass out of ShadowGlen attics that has settled from a nominal R-30 down to effective R-19 or less under Blackland Prairie heat. Rim joist work in Manor typically runs $1,400-$2,600 for a standard home, and we always air-seal the top plates, can lights, and penetrations before any foam goes in. Sealed first, then insulated. In that order.

Garage Ceiling Spray Foam
Garage ceiling spray foam in Manor starts around $1,600-$2,800 for a typical two-car attached garage, and it’s one of the highest-ROI upgrades we do in this market. Here’s why: garage ceilings in these tract homes share the thermal boundary with the house, so un-insulated or thinly insulated garage ceilings let the hottest surface on the property cook the adjacent rooms. Your master bedroom or kitchen shares a wall with that garage. In July, that ceiling surface hits 140°F. We air-seal the garage-to-house penetration - the door frame, any duct chases, the attic hatch - then spray closed-cell or high-density open-cell to bring the assembly up to R-19 minimum, often R-30 where depth allows. The temperature delta across that boundary is immediate and measurable.

Spray Foam Roof Deck
Spray foam applied directly to the roof deck - turning a vented attic into an unvented, conditioned space - runs $4.20-$6.80 per square foot in Manor, with most projects falling between $4,500 and $9,200 depending on roof pitch, square footage, and whether we’re removing existing fiberglass first. This is the right solution for some Manor homes, especially where HVAC equipment lives in the attic and duct losses are the primary problem. But it’s the wrong solution for others, particularly where dark shingle roofs on unshaded lots create sustained surface temperatures that challenge foam durability. We assess roof color, orientation, and existing ventilation before recommending this assembly. The written scope will specify exactly what we’re doing and why.

Before
AfterTrusted Brands We Service in Manor
We source spray foam materials from Icynene, Demilec, and Owens Corning - no proprietary lock-in, no single-source products we have to defend. Each brand has formulations suited to different Manor applications: Icynene’s open-cell products for large attic floors where cost per R-value matters; Demilec’s closed-cell systems for rim joists and garage ceilings where vapor control and structural rigidity are priorities; Owens Corning’s foam and complementary fiberglass systems for hybrid assemblies where we’re capping existing insulation back to spec. We stock common densities and delivery systems locally, so material lead times don’t delay your job. If a specific product makes sense for your assembly, we specify it by name in the written scope. If it doesn’t, we say so.
Common Spray Foam Insulation Problems We See in Manor Homes

- Settled blown fiberglass masquerading as adequate insulation. In Manor’s early-2000s subdivisions, blown fiberglass installed to roughly R-30 has compacted over 15-20 Texas summers into an effective R-19 or lower - a pattern we find consistently when we pull readings in ShadowGlen and similar neighborhoods, often surprising homeowners who assume their “newer” home is already efficient.
- Attic ducts and plenums leaking into 150°F air. The HVAC equipment in your attic is trying to push 55°F air through duct boots and plenum joints that leak directly into ambient temperatures hotter than a sauna. Spray foam applied without air-sealing first masks the real loss. We seal every penetration, every boot, every top plate crack before the foam rig fires up.
- Dark builder roofs on unshaded Blackland Prairie lots. Manor’s flat terrain and sparse tree canopy mean summer radiant loads that older Austin neighborhoods with mature canopy simply don’t experience. Open-cell foam on an exposed roof deck here can degrade if the assembly isn’t designed for sustained 150°F+ surface temperatures. We specify assemblies for the actual conditions, not the catalog.
- Garage ceilings that cook adjacent living space. The attached garage in your 2007-built tract home was insulated to the same minimum standard as everything else - which means barely, if at all. That ceiling is the thermal weak point in your envelope, and spray foam there pays back faster than almost any other single upgrade in Manor’s climate.
Pricing for Spray Foam Insulation in Manor, TX
Most spray foam insulation jobs in Manor fall into these ranges:
| Application | Typical Range | Notes |
|---|---|---|
| Open-cell attic floor (R-38, 5.5-6.5″) | $2,800-$5,200 | Per square foot of attic floor; existing removal extra |
| Closed-cell rim joist/band (2″) | $1,400-$2,600 | Slab-on-grade homes; attic-access top plates |
| Closed-cell garage ceiling | $1,600-$2,800 | Typical 2-car attached; air sealing included |
| Closed-cell roof deck (unvented attic) | $4,500-$9,200 | Includes existing insulation removal; pitch dependent |
| Whole-home hybrid (seal + foam + cap) | $5,800-$11,500 | Air sealing, targeted closed-cell, blown cap to R-49 |
What moves you within these ranges: attic square footage, existing insulation removal (add $0.80-$1.40/sq ft), access difficulty (steep roof pitches, tight scuttles), and whether we’re also air-sealing and running blower-door verification. We don’t do “it depends” without giving you the actual depends. Every estimate is free, every price is written, and every job gets a Documented Photo Record. Call (737) 259-8352 for your specific number - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.

FAQs - Spray Foam Insulation in Manor

Your 2005 builder installed blown fiberglass to minimum IRC code - roughly R-30 nominal - and 15-20 summers on the Blackland Prairie have compacted it to an effective R-19 or lower. We pull this material out of ShadowGlen attics weekly. The “newer home” assumption is costing you on your electric bill. Call (737) 259-8352 for a free assessment and written price.
No. Almost every Manor subdivision is slab-on-grade post-2000 construction, so rim joist spray foam here targets the top plate and band in the attic, not a basement box. Unvented attic conversions are the norm. Our crew knows the assembly details specific to this foundation type. Call (737) 259-8352 and we’ll walk you through what’s actually in your attic.
Closed-cell for rim joists, duct boots, and any surface below R-19 that needs vapor control; open-cell for large attic floors where cost per R-value matters and the assembly includes radiant barrier protection. Open-cell on an exposed dark roof deck in Manor’s 150°F attic conditions can off-gas without proper design. We specify based on your actual roof color, orientation, and existing ventilation - never generic recommendations. Call (737) 259-8352 for a written scope that names the product and why.
Garage ceiling spray foam is a standalone job we do regularly in Manor. It’s often the highest-ROI single upgrade because that ceiling is the thermal weak point cooking your adjacent living space. We air-seal the garage-to-house boundary, then spray to R-19 minimum. Whole-attic work is separate and optional. Call (737) 259-8352 for a written price on either scope.
It changes the temperature your HVAC equipment is fighting against. We were called to a ShadowGlen two-story where the homeowner’s August electric bill had crept past the rest of the block - their builder-grade blown fiberglass in the attic had compacted to about 4 inches and the attic-side HVAC plenum and duct boots were leaking straight into a 150°F attic. We air-sealed the top plates, foamed the band joist and all penetrations with closed-cell, then capped the existing fiberglass back to spec. Supply-temp drop across the coil improved enough that the upstairs never lost the setpoint during a 104°F afternoon. The blower-door reading dropped from 4,200 CFM50 to 2,100. Those numbers are in the homeowner’s documented record. Call (737) 259-8352 for your own assessment.
