Our Spray Foam Insulation Services in Georgetown
Closed-Cell Spray Foam
Closed-cell spray foam - a two-pound density foam that cures rigid and provides both insulation and structural rigidity - is our primary recommendation for Georgetown’s problem areas. It delivers R-6.5 per inch, acts as its own vapor barrier, and is the right choice for rim joists, garage ceilings, and roof decks where moisture management matters. In Sun City Texas homes with slab-on-grade construction, we use closed-cell on rim joists to block the thermal bridging that lets summer heat radiate upward through the slab perimeter. Most closed-cell applications in Georgetown run $2.80-$3.50 per board foot.
Spray Foam Roof Deck
Spray foam applied directly to the underside of the roof deck - creating an unvented, conditioned attic - is the core of our Georgetown Attic Insulation approach and solves the single biggest problem we find in Georgetown’s vaulted cathedral ceilings. In a Sun City Texas courtyard home off Del Webb Boulevard, our crew found the vaulted ceiling over the living area had faced batts sagging away from the roof deck, leaving R-8 where R-38 belonged. We air-sealed the gaps and installed closed-cell spray foam on the roof deck, and the homeowner reported their HVAC runtime dropped noticeably the following week. For builder-grade doors and openers, we also sealed the rim joist and garage ceiling to stop the same heat gain. Roof deck foam in Georgetown typically runs $3.00-$3.80 per board foot, with most projects between $4,500 and $7,200.
Rim Joist Spray Foam
The rim joist - the perimeter band where the foundation wall meets the floor system - is the leakiest part of most slab-on-grade homes, and Georgetown has thousands of them. In Sun City Texas and the post-2010 subdivisions along FM 1460, we consistently find unsealed rim joists leaking conditioned air at rates that make blower-door tests read 30-40% higher than they should. We spray two inches of closed-cell foam here, which hits code vapor barrier requirements and stops the stack effect that pulls hot attic air down through wall cavities in summer. Rim joist sealing in Georgetown averages $1,800-$3,200 for a typical home.
Open-Cell Spray Foam
Open-cell foam - a half-pound density product that stays soft and allows some vapor permeability - works well in above-grade wall cavities and certain attic applications where you want the assembly to dry to the interior. At R-3.6 per inch, it requires more depth than closed-cell to hit Georgetown’s R-38 to R-60 attic code, but it costs less per board foot and performs well in stud bays where space isn’t constrained. We use it selectively, never in below-grade or high-moisture areas. Open-cell in Georgetown runs $1.80-$2.40 per board foot.
Garage Ceiling Spray Foam
Garage ceilings in Georgetown - especially in homes where the garage sits under conditioned space - are often completely uninsulated or covered with a thin layer of batts that do nothing to stop air movement. We spray foam garage ceilings to create a thermal and air barrier between the garage and living space above, which matters in July when your garage hits 120°F and that heat radiates straight into bedrooms. Garage ceiling treatments in Georgetown typically run $2,200-$4,000.

Common Spray Foam Insulation Problems We See in Georgetown Homes
- Faced batts in vaulted Sun City ceilings sag away from the roof deck within 10-15 years, leaving R-8 or less and invisible hot spots that force HVAC systems to run nonstop in July and August. We find this in nearly every Del Webb home built before 2008 that hasn’t had insulation upgraded.
- Post-2010 master-planned subdivisions were built to builder-minimum insulation specs that don’t meet IECC Zone 3A R-38 to R-60 requirements. The blown-in fiberglass in these attics has often settled 20-30% below labeled R-value, and the rim joists were rarely air-sealed at all.
- Winter Storm Uri showed that poorly insulated attics in Georgetown don’t protect pipes or HVAC equipment when temperatures drop into the single digits. Spray foam on roof decks and rim joists creates the thermal envelope that prevents freeze damage when the next polar vortex arrives.
- Garage ceilings are routinely left uninsulated in both Sun City and newer subdivisions, turning attached garages into radiant heat sources that overload upstairs HVAC zones through August.

FAQs - Spray Foam Insulation in Georgetown
Yes - spray foam on the roof deck is the most effective solution for Sun City’s vaulted cathedral ceilings, where original faced batts have sagged to R-8 or less. We remove the failed batts, air-seal all penetrations, and spray closed-cell foam directly to the roof deck, creating a conditioned, unvented attic space that meets R-38 code and stops the hot spots that force your HVAC to run continuously. Most Sun City roof deck projects run $4,500-$7,200. Call (737) 245-6428 for a written price - estimates are free.
No - post-2010 master-planned homes in Georgetown were typically insulated to builder-minimum specs that fall well below IECC Climate Zone 3A’s R-38 to R-60 requirement, and the blown-in fiberglass has often settled 20-30% below labeled value. We regularly test these homes with blower-door equipment and find air leakage rates 40-60% above what a properly sealed envelope should read. Spray foam, combined with air sealing of top plates and penetrations, brings them to code and cuts cooling load substantially. Call (737) 245-6428 for a written price - estimates are free.
Spray foam creates a continuous thermal and air barrier that protects pipes and HVAC equipment located in attic or rim joist areas when temperatures drop into the single digits. During Uri, poorly insulated Georgetown homes lost heat so rapidly that attic-located air handlers and ductwork froze; closed-cell spray foam on roof decks and rim joists maintains the conditioned envelope that prevents this. The air-sealing component is equally critical - leaks that let cold air reach plumbing chases are what cause burst pipes, not just low insulation alone. Call (737) 245-6428 for a written price - estimates are free.
Start with the rim joist and any vaulted or cathedral ceilings, followed by the garage ceiling if conditioned space sits above it. These three areas produce the fastest comfort improvement and utility reduction in Georgetown’s housing stock. In Sun City homes, the roof deck over vaulted ceilings is almost always the priority; in post-2010 subdivisions, it’s typically the rim joist and attic floor transition. We assess with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - and give you a written priority list before any work starts. Call (737) 245-6428 for a written price - estimates are free.
Spray foam installation does not void builder warranties when performed by a licensed contractor following manufacturer specifications and ICC building codes. We document our work with photos, product data sheets, and installation thickness readings, and we coordinate with your builder’s warranty department if needed. Our 365-Day Done Right Promise covers our workmanship regardless of your builder’s warranty status. Call (737) 245-6428 for a written price - estimates are free.
