Call (254) 970-2136 for a written price before any work starts.
We’ve worked in Shady Hollow long enough to know the pattern: a 1985 ranch near the Escarpment Oaks entrance, a two-story off Slaughter Creek Drive, a workshop out on one of the larger lots past the Shady Hollow Community Center. The homes vary, but the underlying condition is consistent. Thirty to forty years of original blown-in fiberglass or batt insulation, compressed by time and by the leaf litter that slides down from those mature live oaks and cedar elms into vented soffits. The result is an attic that looks insulated on a quick visual check but performs far below current Climate Zone 2 standards.
Why Topside Attic Insulation Georgetown Is Shady Hollow’s Preferred Spray Foam Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in the Shady Hollow area and nearby Southwest Austin communities. Our Spray Foam Insulation in Shady Hollow customers tend to leave the same feedback: the crew showed up when promised, the written scope matched what was delivered, and the blower-door numbers proved the result. We don’t ask you to trust us; we hand you documentation.
Response time to Shady Hollow is typically same-day or next-day for estimates, with most foam jobs scheduled within a week. Dispatch and scheduling are coordinated from our Austin office, but the crews serving Shady Hollow live locally and know the area. They know which streets narrow to single-lane after rain, which lots have the detached workshops that need their own approach, and which homes back up to the Slaughter Creek greenbelt where the canopy is thickest and the debris load heaviest.
Our 365-Day Done Right Promise applies to every Shady Hollow job. If it’s not done right, we make it right. That’s Haven Standard Clause 3, and it’s in writing before anyone starts.
Our Spray Foam Insulation Services in Shady Hollow
Open-Cell Spray Foam
Open-cell spray foam in Shady Hollow runs $1.80-$2.80 per board foot and is what we use most often for attic floors and roof decks in the neighborhood’s vented-attic homes. The material expands to roughly 3.5 inches per pass, fills irregular framing cavities well, and provides both insulation and an air barrier in one application. On a typical 2,200-square-foot Shady Hollow home, an open-cell attic job runs $3,800-$5,400. We specify Icynene or Demilec open-cell products, sourced through standard distribution channels with no proprietary lock-in.
Closed-Cell Spray Foam
Closed-cell spray foam in Shady Hollow costs $3.50-$5.50 per board foot and is what we use for rim joists, crawl spaces, and any application where moisture resistance or structural rigidity matters. The R-value per inch is roughly double open-cell, so it achieves code minimums in tighter spaces. On Shady Hollow’s slab-on-grade homes, closed-cell at the rim joist is often the difference between a conditioned space and one that bleeds air through the foundation wall. A typical closed-cell rim-joist job in a Shady Hollow home runs $1,200-$2,400.
Rim Joist Spray Foam
Rim joist spray foam is the most overlooked upgrade in Shady Hollow’s 1980s housing stock. The band joist where the sill plate meets the foundation is often completely unsealed, creating a direct path for 140-160°F attic air to drop into wall cavities or for winter air to chill interior floors. We foam rim joists with closed-cell after verifying there’s no active moisture intrusion, and we include before-and-after blower-door readings so you can see the exact CFM50 reduction. Most Shady Hollow rim-joist jobs are completed in four to six hours.
Garage Ceiling Spray Foam
Garage ceiling spray foam in Shady Hollow addresses a specific problem: rooms above or adjacent to unconditioned garages that never reach set temperature. The garage ceiling is often a single layer of drywall with no air barrier, and the conditioned space above it pays the penalty. We see this frequently on two-story homes near the Shady Hollow Community Center, where bonus rooms or bedrooms sit over garages. Open-cell foam at the garage ceiling, combined with air sealing of penetrations and the top plate, typically runs $2,400-$4,200.

Before
AfterTrusted Brands We Service in Shady Hollow
We source spray foam materials from Icynene, Demilec, and Owens Corning, among others, with no exclusive arrangements that would limit your options or inflate your price. For Shady Hollow jobs, we stock common open-cell and closed-cell formulations locally, which means no multi-day wait for material delivery and no crew standing idle while a truck drives up from San Antonio. If a specific product or density is specified by an engineer or energy rater, we can source it. If you’re not sure what you need, we specify based on the application, the cavity depth, and the performance target, and we put that specification in writing.
Common Spray Foam Insulation Problems We See in Shady Hollow Homes
- Live-oak and cedar-elm debris crushing eave insulation. The canopy that gives Shady Hollow its name sheds leaves, twigs, and pollen that accumulate in vented soffits over decades. We’ve pulled soffit baffles on 1980s homes and found the original batts compressed to half their labeled thickness, with moisture staining on the sheathing that would have been trapped under any new foam if we hadn’t removed it first.
- Detached workshops with unsealed rim joists and open framing. Many Shady Hollow lots include outbuildings that were never intended as conditioned space but are now used as offices, studios, or equipment storage. The open framing at the sill plate and the lack of any air barrier means these buildings are essentially outdoor space with a roof. Closed-cell rim-joist foam and wall cavity foam, combined with proper air sealing, converts them to usable conditioned space.
- Settled blown-in fiberglass masking bypasses at the top plate. Original 1980s fiberglass in Shady Hollow attics has often settled below the top plate of exterior walls, creating hidden air channels that bypass the insulation entirely. A depth-based estimate misses this; thermography and a blower-door test find it. We seal these bypasses before foaming, or the new foam sits on top of a leaky attic floor.
- Assumed Austin Energy rebate eligibility. Because Shady Hollow sits in unincorporated Travis County, not the City of Austin, rebate pathways differ. We verify eligibility by service address before quoting any rebate-dependent pricing, so you’re not surprised by a denied application after the job is complete.
Pricing for Spray Foam Insulation in Shady Hollow, TX
Here’s what spray foam insulation costs in the Shady Hollow market, based on jobs we’ve completed in the neighborhood over the past two years:
| Application | Material | Typical Range |
|---|---|---|
| Attic floor (open-cell) | Icynene or Demilec | $3,800 - $5,400 |
| Attic roof deck (open-cell) | Icynene or Demilec | $4,200 - $6,800 |
| Rim joist (closed-cell) | Demilec or Owens Corning | $1,200 - $2,400 |

These ranges assume standard framing, accessible cavities, and no active remediation needed for mold or rodent damage. What moves a job toward the top of the range: air sealing of more than twenty top-plate penetrations, can-light enclosures, chimney chase blocking, or extensive soffit debris removal. What keeps it at the lower end: clean cavities, recent electrical work with accessible boxes, and a straightforward attic layout. We give you a flat written price before any work starts.

FAQs - Spray Foam Insulation in Shady Hollow
We typically schedule Shady Hollow estimates within 24-48 hours, and most foam jobs start within a week of approval. Dispatch runs from our Austin office, but the crew assigned to your job is local to the Shady Hollow area. Call (254) 970-2136 to book a time that works.
Yes. We work throughout the original Shady Hollow subdivisions, the Estates of Shady Hollow, and the acreage properties along the Slaughter Creek greenbelt. The larger lots with detached workshops are actually where we do some of our most detailed work, since those buildings often need rim-joist sealing and wall cavity foam that the main house doesn’t.
We don’t classify insulation as an emergency trade, but we do answer calls 24/7 and can often move Shady Hollow jobs up in the schedule if there’s an active issue like a roof leak that has saturated insulation or a rodent infestation that requires removal and re-insulation. A live person answers; there’s no voicemail loop.
Material and labor rates are consistent across our service area, but Shady Hollow jobs sometimes run slightly higher because of the unincorporated-county permit pathway and the additional air-sealing work that 1980s homes typically need. A comparable open-cell attic job in a newer Round Rock build might land at the lower end of our range; a Shady Hollow job with extensive top-plate sealing and soffit debris removal lands higher. We quote flat by job, not by ZIP code.
Every Shady Hollow job carries our 365-Day Done Right Promise and a written manufacturer’s warranty on the foam product itself. The Done Right Promise means if the performance doesn’t match the written scope, we return and correct it. The manufacturer’s warranty covers product defect for as long as you own the home, typically 15-25 years depending on the brand. Both are delivered in writing before work starts, under Haven Standard Clause 1.
Call (254) 970-2136 today for a free estimate on spray foam insulation in Shady Hollow. We’ll send a technician who knows the neighborhood, run a blower-door test if the job warrants it, and leave you with a written price before anyone lifts a tool.
