Fast, Reliable Spray Foam Insulation Across Manor
Spray foam insulation in Manor, TX typically runs $2.80-$4.20 per board foot for open-cell and $4.50-$7.00 per board foot for closed-cell, with most full attic jobs landing between $3,200 and $6,800 depending on square footage and whether we need to air-seal first. Our crews are on the road to Manor within the hour from our Austin dispatch office, and we carry both Icynene and Demilec material sets so we’re not waiting on a delivery truck before we can start your job. Call (737) 337-8049 for a written price before any work starts - that’s Haven Standard Clause 1, no exceptions.
We’ve sealed and insulated over 9,000 homes since 2016, and a surprising number of them have been right here in Manor - not in the historic core, but in the subdivisions that went up fast along East US Highway 290 and Pickle Parkway after 2000. These aren’t old houses with charming quirks. They’re nearly identical tract homes with the same attic problems repeated block after block, which means we know what we’re walking into before we even pull onto your street.
Why Topside Attic Insulation San Marcos Is Manor’s Preferred Spray Foam Insulation Company
Manor homeowners don’t hire us because we’ve been around longest. They hire us because we publish the blower-door numbers - the pressurization reading that shows, in one figure, how much conditioned air your home was losing before we started and how much less it loses after we’re done. That documentation matters in a market where every contractor promises “energy savings” but few can prove they achieved them.
Our reviews from Manor customers mention the same things repeatedly: the technician showed up in a marked truck and uniform, the price on the page matched the price on the invoice, and the photo record arrived by text before the crew left the driveway. We don’t have a callback window measured in business days - a live person answers calls 24/7, and our crews typically reach Manor properties within 45 minutes to an hour during standard dispatch hours.
We also know the local permitting rhythm. Manor falls under Travis County’s unincorporated jurisdiction for some addresses and the City of Manor for others, particularly the newer builds in Magnolia Ranch Estates and Oak Creek Estates. We’ve pulled permits on both sides and know which inspector wants to see the fire-retardant rating on the foam spec sheet and which one is looking for the thermal-barrier documentation. That local knowledge keeps jobs moving instead of stalling at the inspection stage.
Our Spray Foam Insulation Services in Manor

Open-Cell Spray Foam
Open-cell spray foam is our most common recommendation for Manor’s vented attics - the ones in Presidential Glen, Presidential Meadows, and the other post-2000 subdivisions that make up most of the local housing stock. At roughly $2.80-$4.20 per board foot installed, it delivers R-3.6 to R-3.8 per inch, and at 5-6 inches on a flat ceiling deck it hits the R-19 to R-21 range that actually performs in this climate. The key detail most contractors skip: open-cell must be paired with air sealing of the can-light grid and attic hatch first, or you’re foaming over a sieve. We seal, then we foam - in that order, always.

Closed-Cell Spray Foam
Closed-cell runs $4.50-$7.00 per board foot and delivers R-6 to R-7 per inch, making it the right choice for rim joists in crawl spaces, garage ceiling assemblies, and any application where moisture resistance or structural rigidity matters. In Manor, we specify closed-cell for garage ceiling jobs more often than attic jobs - the garage is where we find uninsulated supply lines and the plumbing penetrations that froze during Winter Storm Uri. Closed-cell at 2-3 inches on a garage ceiling creates a vapor barrier and thermal break in one pass, which matters when your water heater and HVAC air handler live in that same unconditioned space.

Rim Joist Spray Foam
The rim joist - the band where your foundation wall meets the first floor - is the single most under-insulated detail in Manor’s slab-on-grade tract homes. Builders stuffed fiberglass batts in there if they did anything at all, and after a few seasons that batt is black with dust, compressed, and doing nothing. We remove it and apply closed-cell spray foam directly to the rim, typically 2-3 inches, which seals the sill plate against air infiltration and raises the surface temperature above the dew point. In Lockwood Farms and the older sections of Presidential Meadows, this is often the fix that stops the musty smell in winter and the cold-floor complaint the homeowner couldn’t trace.

Garage Ceiling Spray Foam
Manor’s builders left garage ceilings uninsulated or barely insulated in nearly every home we’ve entered. The result: bedrooms above the garage run 8-12°F warmer in summer, and any plumbing routed through that garage ceiling is exposed to freeze risk. Our garage ceiling spray foam jobs run $1,800-$3,400 for a typical two-car garage, and we always scope the rim joist and any duct penetrations while we’re in that space - it’s cheaper to do it once than to come back after a pipe splits. The field vignette we see repeatedly: a homeowner in Presidential Glen who finally understood why their master bedroom was uninhabitable in July, and why their water line froze in February. Same garage, same uninsulated ceiling, same two problems.

AfterTrusted Brands We Service in Manor
We source spray foam materials from Icynene and Demilec, among others, and we don’t lock you into a proprietary product line. Icynene’s open-cell formulations are what we typically specify for Manor’s vented attic assemblies - they’ve been tested in Climate Zone 2 conditions and the spec sheets satisfy Travis County’s fire-retardant requirements. Demilec’s closed-cell products go in where we need vapor barrier performance, particularly garage ceilings and rim joists. We keep both material sets stocked at our Austin warehouse, so a Manor job doesn’t wait on a freight delivery from Dallas or Houston. If you’ve got a preference based on prior research or a builder’s spec, we’ll walk through the data sheet with you and quote accordingly - no brand is pushed, no brand is excluded.
Common Spray Foam Insulation Problems We See in Manor Homes

- Collapsed builder batts masquerading as R-19. In Presidential Glen and Presidential Meadows, we regularly open attic hatches to find R-19 fiberglass batts compressed to R-8 or less along the eaves, where they were stuffed into bays too shallow for their labeled thickness. The homeowner sees the right depth near the hatch and assumes the whole attic matches - it doesn’t.
- Can-light grids that defeat any insulation you add. Those identical DR Horton floor plans put six to ten can lights in a grid across the master bedroom and living room ceiling, each one a 6-inch hole straight into the attic. Spray foam the ceiling deck without sealing those penetrations first, and you’ve built a slightly better insulated sieve.
- East-facing takeoffs baking in full Prairie sun. Homes on the east side of Bella Vista at Cottonwood Creek and the eastern edges of Oak Creek Estates get hammered by sunrise-to-noon exposure across flat, treeless terrain. Their attic ventilation can’t keep pace, and the spray foam thickness has to be calculated for that heat load - not for a shaded lot in Austin’s canopy cover.
- Missing vent chutes at the eave edge. Manor’s builder-grade installations often skipped baffles entirely, meaning any spray foam applied at the eave can block soffit intake and create a moisture trap. We install vent chutes as part of the air-sealing phase, before the foam gun comes out.

FAQs - Spray Foam Insulation in Manor

Your “newer” Manor home likely has builder-grade R-19 batts that have compressed to R-8 or less, plus an unsealed can-light grid and attic hatch that leak conditioned air continuously. Spray foam makes sense because it replaces the failed material and creates an air barrier in one step - something fiberglass batts were never designed to do. Call (737) 337-8049 for a written price and we’ll show you the blower-door numbers that prove the difference.
We seal every can-light penetration with a fire-rated cover or gasket before foam touches the ceiling deck - foaming over them without sealing first would trap heat and create a fire hazard. In Presidential Meadows specifically, we know the grid pattern from the DR Horton floor plan before we arrive, so we scope the sealing work accurately and don’t discover surprises halfway through the job. The foam goes on after the penetrations are sealed, not before.
Open-cell is the right choice for nearly all Manor vented attics - it’s cost-effective at the thickness needed for Climate Zone 2, and it allows assembly drying if moisture ever gets in. Closed-cell belongs in rim joists, garage ceilings, and any application where you’re creating a conditioned space from an unconditioned one. We’ll specify based on what your attic actually is, not what we prefer to install.
Yes, if it’s applied to the right locations - specifically the garage ceiling, rim joist, and any plumbing wall penetrations where cold air infiltrates. Spray foam on the attic flat ceiling won’t protect a water line running through an uninsulated garage ceiling below it. We scope the full envelope, not just the obvious spots, and we document where foam was applied and where it wasn’t so you know exactly what’s protected. Call (737) 337-8049 and we’ll walk through your specific risk points.
Often yes - if you’re in Presidential Glen, Presidential Meadows, or another of the DR Horton-era subdivisions, we’ve worked your exact floor plan enough times to scope material and labor accurately from the address and satellite imagery. We still perform a pre-work inspection to confirm attic condition and access, but the written price you receive upfront is based on real data, not a guess. Homes in Lockwood Farms, Magnolia Ranch Estates, or custom builds may need a quick site visit first; either way, the estimate is free.
