Fast, Reliable Spray Foam Insulation Across Manor
Most spray foam insulation jobs in Manor run between $2,800 and $7,500 depending on whether you’re sealing an attic, a garage ceiling, or a full roof deck, and our crews typically start work within 3-5 business days of your written estimate. We dispatch from our Austin office and serve Manor directly, including ShadowGlen, Wildhorse Creek, and the new builds along FM 973 and US 290. If your summer electric bills are climbing despite a relatively new home, the problem usually isn’t your insulation’s age - it’s that the builder never sealed the air leaks before installing it.

Why Topside Attic Insulation Cedar Park Is Manor’s Preferred Spray Foam Insulation Company
We’ve worked in enough Manor attics to recognize the exact failure pattern before we even pull down the hatch. Since 2016, our Spray Foam Insulation team has documented every job with before-and-after blower-door numbers, and that evidence is what Manor homeowners cite most often in reviews - not promises, but pressurization readings they can see.
Response time to Manor is typically same-day for estimates and 3-5 days for crew dispatch, depending on material staging. We know the difference between a ShadowGlen two-story with a low-slope attic and a Wildhorse Creek ranch with a vented roof, and we price accordingly - no flat-rate guessing that leaves you underwater on labor.
Our technicians are background-checked and uniformed, and a live person answers calls 24/7. That matters when you’re trying to coordinate access to a home off Parsons Street or need to confirm arrival time while you’re stuck in Austin traffic heading east.
Under Haven Standard Clause 1, every Manor job starts with a written price, written scope, and written warranty before anyone lifts a tool. No exceptions. We also offer a Free Second Opinion on any competing written estimate - bring us another contractor’s scope and we’ll read it with you line by line.
Our Spray Foam Insulation Services in Manor

Open-Cell Spray Foam
Open-cell spray foam in Manor runs $1.80-$2.40 per board foot installed and works best for attic floors and wall cavities where you need both insulation and air sealing at a lower material cost than closed-cell. In Manor’s post-2000 tract homes, we use open-cell to fill stud bays and ceiling planes after we’ve first sealed the top plates and can light penetrations - the step the builder skipped. The foam expands to fill irregular cavities, which matters in production-built homes where framing isn’t always straight. One caveat: in low-slope Manor attics that hit 150-160°F, open-cell must be applied at proper thickness and temperature-controlled conditions to avoid off-gassing and density loss.

Closed-Cell Spray Foam
Closed-cell spray foam in Manor attics and rim joists typically costs $2.80-$3.80 per board foot and provides R-6.5 per inch plus a vapor barrier in a single application. This is our choice for Manor’s slab-on-grade homes where rim joists sit close to grade and need both insulation and moisture management - the Blackland Prairie humidity east of Austin makes vapor control non-negotiable. We also use closed-cell to seal HVAC drop soffits and recessed can light surrounds before adding any other insulation, because stopping air movement matters more than adding R-value over a leak. In ShadowGlen and similar subdivisions, this two-step process - seal first, insulate second - is what separates a performance job from a cosmetic one.

Rim Joist Spray Foam
Rim joist spray foam in Manor slab homes runs $1,200-$2,400 for a typical single-story and $1,800-$3,600 for a two-story, depending on linear footage and accessibility. Manor’s housing stock is overwhelmingly slab-on-grade, and the rim joist - where the foundation wall meets the floor system - is often completely uninsulated in production builds. We spray closed-cell foam directly to the rim joist cavity, creating an air seal and thermal break where cold air enters in winter and humid air condenses in summer. This is one of the highest-impact, lowest-visibility upgrades you can make in a Manor tract home, and it’s almost never done right by the original builder.

Garage Ceiling Spray Foam
Garage ceiling spray foam in Manor costs $2,400-$4,800 for a typical two-car garage and addresses the thermal bridge between a hot garage attic and conditioned space above. In Manor’s newer subdivisions, bonus rooms and bedrooms over garages are common, and the garage ceiling is often a single layer of drywall with no air sealing at penetrations. We spray open-cell foam to the garage ceiling plane, sealing around electrical and HVAC penetrations, which drops the temperature delta between garage and living space by 15-25°F in peak summer. This matters on FM 973 corridor homes where afternoon sun pounds the garage roof and the room above becomes unusable until midnight.

Trusted Brands We Service in Manor
We source spray foam materials from Johns Manville, Knauf, and CertainTeed - no proprietary lock-in that limits your options or inflates your price. For Manor jobs, we stage Johns Manville and Knauf open-cell products from our Austin warehouse, which keeps lead times short and lets us match the right foam density to your specific attic conditions. CertainTeed closed-cell is our standard for rim joist and roof deck applications where vapor impermeability matters. We document the product lot numbers on every job, included in your Documented Photo Record, so you have a chain of custody if any issue arises.
Common Spray Foam Insulation Problems We See in Manor Homes

- Builder-grade R-30 batts sitting over unsealed air channels. In ShadowGlen and comparable Manor subdivisions, production builders blew insulation over unsealed recessed cans, HVAC drop soffits, and top-plate penetrations. The insulation filters attic air instead of stopping it, which is why your new home’s electric bill looks like a 1970s ranch’s.
- Open-cell foam applied too thin in extreme attic heat. Manor’s low-slope tract-home attics hit 150-160°F in July and August. Foam installed at inadequate thickness or during peak afternoon temperatures can shrink, crack, or off-gas, leaving you with R-value on paper and air leaks in reality.
- Vapor management ignored on roof deck retrofits. The Blackland Prairie’s higher humidity east of Austin means spray foam at the roof deck must account for both thermal performance and moisture drive. Closed-cell foam applied without calculating dew point can trap condensation against sheathing, especially in Manor’s slab homes where ground moisture contributes to the load.
- Rim joists left completely exposed. Nearly every post-2000 Manor slab home we’ve inspected has bare rim joists - no insulation, no air seal, just raw wood and concrete where outdoor air enters the floor system. Summer humidity condenses here; winter cold air pours through. It’s invisible, expensive, and fixable in a single day.
Pricing for Spray Foam Insulation in Manor, TX

FAQs - Spray Foam Insulation in Manor

Your R-30 batts are sitting over unsealed air channels - recessed can lights, HVAC soffits, and top-plate gaps that the builder never foamed or caulked before insulation went in. The insulation filters 150°F attic air instead of blocking it, so your AC runs continuously to replace the conditioned air leaking out. We see this in nearly every ShadowGlen home we inspect. Call (737) 245-6428 for a free estimate - we’ll show you the gaps with a blower-door test and photo documentation.
More blown insulation over unsealed leaks makes the problem worse by burying the air channels deeper and harder to access. Spray foam - specifically closed-cell at the penetrations, then open-cell or blown at the ceiling plane - is what actually stops the air movement. In Manor’s production-built homes, the fix is seal first, insulate second, always. Bring us any competing quote and we’ll review it with you at no charge.
Closed-cell is more stable in extreme heat and provides vapor control, but it’s also more expensive. For most Manor attic floors, we use closed-cell at the penetrations and soffits (where air sealing matters most), then open-cell across the ceiling plane for cost efficiency. Full roof deck encapsulation in a hot attic requires closed-cell throughout, with thickness calculated to keep the dew point outside the sheathing. We’ll specify which approach your attic needs in the written scope.
Yes. Rim joists are accessible from the basement or crawl space - or from the exterior in some cases - without interior wall demolition. In Manor’s slab-on-grade homes, the rim joist sits at foundation level, and we spray closed-cell foam directly to the exposed wood and concrete interface. Most single-story jobs finish in four to six hours. Call (737) 245-6428 for a written price specific to your foundation type.
Higher humidity means more moisture drive from both outdoor air and ground vapor, which makes vapor-permeability calculations critical. Closed-cell spray foam at the roof deck must be thick enough to keep the interior sheathing surface above dew point year-round; too thin, and summer humidity condenses against the wood. We run dew-point analysis for every Manor roof deck job and document the target thickness in your written scope before application starts.
