Georgetown’s combination of hot, humid summers and occasional hard freezes puts unusual stress on a home’s building envelope. We’ve worked in homes from the historic districts near Southwestern University to newer construction in Sun City and the Teravista area for Spray Foam Insulation - Georgetown projects, and the pattern is consistent: Texas heat gains through poorly insulated roof decks force air conditioning systems to run longer than necessary, while winter cold snaps find every gap in rim joists and garage ceilings. Our approach treats air sealing as a prerequisite, not an add-on. We seal top plates, can lights, and penetrations before any foam goes in, then document the result with before-and-after blower-door numbers you can read yourself.

Our crews are background-checked and uniformed, and a live person answers our phones 24 hours a day. When you call (254) 970-2136, you’ll speak to someone who can schedule your free estimate, not a voicemail system with a callback window measured in business days.

What Our Spray Foam Insulation Service Includes

Open-Cell Spray Foam

Open-cell spray foam is a lightweight, semi-rigid foam with a density of about 0.5 pounds per cubic foot, expanded with water rather than chemical blowing agents. In Georgetown’s climate, we use it most often for attic floor applications and interior wall cavities where its vapor-permeable nature allows assemblies to dry to the interior. At Topside Attic Insulation Georgetown, we specify open-cell only after confirming the assembly can manage moisture without an additional vapor retarder, and we never install it below grade where bulk water is a risk. Every open-cell job includes a written scope specifying the target thickness and R-value, plus a Documented Photo Record showing coverage before the drywall goes back.

Closed-Cell Spray Foam

Closed-cell spray foam runs 2.0 pounds per cubic foot, acts as its own vapor retarder at thicknesses above 1 inch, and adds structural rigidity to framed assemblies. We use it in Georgetown for rim joists, crawl space walls, and any application where space is limited and maximum R-value per inch matters. In homes near the San Gabriel River with higher humidity exposure, closed-cell’s water resistance makes it the appropriate choice for below-grade and transition areas. Our crews meter the substrate moisture content before spraying, because foam applied over damp wood delaminates within months. The written price you receive specifies whether we’re quoting closed-cell, and why.

Rim Joist Spray Foam

The rim joist, also called the band joist, is the perimeter framing member where the floor system meets the foundation wall. It’s the leakiest part of most Georgetown homes, responsible for up to 20% of total air leakage in a typical single-story house. We spray closed-cell foam here to seal the joint between sill plate and foundation, between rim joist and subfloor, and around any plumbing and wiring penetrations. In older Georgetown homes near the square, we’ve found rim joists with no insulation at all, or with degraded fiberglass batts that never sealed air movement. After we finish, the blower-door test shows the difference in a single number.

Garage Ceiling Spray Foam

Garage ceilings with living space above are thermal bridges in most Georgetown homes, especially in neighborhoods like Berry Creek and Cimarron Hills where bonus rooms over garages are common. We spray open-cell foam against the garage ceiling drywall or roof deck, depending on whether the garage is conditioned, creating a continuous thermal boundary. The critical detail is sealing the garage-to-house wall and any ductwork passing through the garage before insulating, because garage air contains carbon monoxide and volatile compounds you don’t want migrating into bedrooms. Our written scope specifies both the insulation and the air-sealing sequence.

Spray Foam Roof Deck

Spraying foam directly to the underside of the roof deck converts an attic from vented to unvented, bringing ductwork and mechanical equipment inside the conditioned space. In Georgetown’s climate, this eliminates the 30-40°F temperature swing that vented attics experience in summer, reducing cooling load and extending HVAC equipment life. We use open-cell foam on roof decks in most cases, with a vapor-retarder coating or smart membrane where code requires it. The key detail most contractors miss: the existing attic ventilation must be sealed at the ridge and soffits, or you’ll pressurize the attic and drive moisture into the roof assembly. We document this sealing with photos, and the blower-door test confirms we didn’t miss anything.

Brands We Service for Spray Foam Insulation

We’ve installed Icynene open-cell systems in hundreds of Georgetown-area homes, particularly in the energy-efficient builds near Wolf Ranch and the new construction along Ronald Reagan Boulevard. Icynene’s water-blown formulation produces low VOC emissions during curing, and we’ve found their published R-values hold up consistently in field conditions. We don’t push any single brand, but when a homeowner’s architect or builder specifies Icynene, we have the equipment training and supplier relationship to honor that spec without substitution.

Demilec closed-cell products are our typical choice for rim joist and below-grade work in Georgetown’s older homes, where their higher compressive strength and moisture resistance matter more than cost per board foot. We’ve also used CertainTeed spray foam systems where the builder’s warranty requires a specific brand for envelope continuity. Whether your project specifies Icynene, Demilec, CertainTeed, or another manufacturer, we source materials without proprietary lock-in and install to the same Haven Standard: written scope, written price, documented result. If you have a preferred brand or a competing quote that specifies one, bring it to us for a free second opinion.

Signs You Need Spray Foam Insulation Right Now

• Your second floor is consistently 8-12°F warmer than the first floor in summer. This temperature stratification means conditioned air is leaking out of the top of your building envelope faster than your HVAC can replace it. In Georgetown’s July heat, an unsealed attic with inadequate insulation can reach 140°F, turning your ceiling into a radiant heater. We measure the leakage with a blower-door test and seal the paths air is actually taking.
• Your energy bills spike every June and stay high through September. Most Georgetown homeowners see a seasonal increase, but if your summer bills are 40% or more above your winter baseline, your thermal boundary is failing. Spray foam addresses both the insulation value and the air leakage that drives excessive cooling load.
• You can see daylight through rim joists in your basement or crawl space. Gaps at the foundation perimeter are direct connections to outside air, and in Georgetown’s clay soils, they also admit soil gas and moisture. Closed-cell spray foam seals these gaps permanently, unlike fiberglass batts that sag and degrade.
• Your garage ceiling has no insulation, or the insulation is falling down. This is common in Georgetown homes built before 2010, and it means any rooms above the garage are effectively exposed to outside temperatures. Spray foam adheres to irregular surfaces and stays in place, unlike batt products that rely on friction fit.
• Your HVAC contractor has suggested upsizing your air conditioner. Before you spend $8,000-$15,000 on larger equipment, have us run a blower-door test. Most Georgetown homes lose 30-50% of conditioned air through leaks, not inadequate equipment capacity. Sealing and insulating with spray foam often reduces the actual load enough that your existing system can handle it.

Our Spray Foam Insulation Process - Step by Step

1. 1
   On-site assessment and blower-door test. We arrive on schedule, with a named technician who texts when they’re on the way. The blower-door test, a pressurization reading that shows in one number how much air your building envelope is losing, establishes your baseline. We photograph existing conditions, identify thermal bypasses, and explain what we found before proposing any work.
2. 2
   Written price and scope delivered. Under Haven Standard Clause 1, you receive a flat price, written scope, and written warranty before anyone lifts a tool. No verbal estimates, no “we’ll figure it out when we get in there.” The scope specifies foam type, target thickness, R-value, and every air-sealing step that precedes insulation.
3. 3
   Air sealing before insulation. We seal top plates, electrical penetrations, can lights, duct boots, and any other leakage paths with appropriate materials, caulk, or gasket. In Georgetown’s older homes, this step often takes longer than the foam application itself. We don’t skip it, and we don’t charge extra when we find more leaks than expected, because the written price covers the result, not the time.
4. 4
   Spray foam application with real-time monitoring. Our crews monitor substrate temperature, ambient humidity, and foam lift thickness during application. Closed-cell foam goes on in 1-inch passes to prevent exothermic cracking; open-cell is built to the specified thickness in controlled lifts. We photograph coverage as we go, so you can verify complete treatment even in areas you’ll never see again.
5. 5
   Final blower-door test and documentation. After the foam cures, we run the blower-door test again and compare to your baseline. The reduction in CFM50, measured and recorded, is proof of performance you can keep. You receive a Documented Photo Record of the work, the before-and-after blower-door readings, and your written warranty under the 365-Day Done Right Promise.
