GreenFiber Blown-In Insulation in Georgetown: What to Know First
We provide independent GreenFiber blown-in insulation service in Georgetown, with most attic jobs completed in one day and a written price delivered before any work starts. Most GreenFiber blown-in cellulose installations in a Georgetown home this size run between $1,800 and $3,400 for a full attic, or $900 to $1,500 for a top-up over existing insulation. This page is for homeowners who already have GreenFiber insulation in their attic or walls and need service, replacement, or an upgrade - whether you’re in Sun City Georgetown, along the San Gabriel River corridor, or anywhere in between. Call (254) 970-2136 for a free estimate with a written scope and no obligation.
How GreenFiber Products Fail - and How We Fix Them
- GreenFiber All Borate Cellulose settling below labeled R-value in attics over 10 years old. Georgetown’s 140°F summer attic temperatures accelerate compaction, dropping the effective R-value from R-38 to R-25 or lower. We measure actual depth with a calibrated probe, calculate the settled density, and blow new All Borate to restore full thickness rather than guessing by bag count.
- GreenFiber Sanctuary blown-in insulation bridging over recessed can lights that were never properly air-sealed. The cellulose forms a thermal bridge around hot fixtures, creating a reverse stack effect that pulls conditioned air upward. We pull back the Sanctuary, seal each can light with a fire-rated cover and foam, then reblow - Seal the holes first. Then we talk about R-value.
- GreenFiber Low Dust formula absorbing moisture from roof leaks or bathroom vent discharge. The borate treatment resists mold but not saturation; once wet, the fibers mat and the weight stresses ceiling drywall. We remove the damaged section with a vacuum rig, thermal-image the roof deck to find the leak source, and replace with fresh Low Dust only after the repair is documented.
- GreenFiber stabilized cellulose in dense-pack wall cavities slumping in balloon-framed homes near downtown Georgetown. The adhesive additive breaks down with repeated humidity cycling from the San Gabriel River floodplain. We drill new fill holes, test cavity density with a wall probe, and repack at 3.5 pounds per cubic foot - the density GreenFiber specifies but many installers miss by under-blowing.
- GreenFiber insulation contaminated by rodent activity in older Georgetown subdivisions like Serenada. Borate deters insects but doesn’t stop nesting; the urine soaks through and the odor recirculates via duct leakage. We remove the affected material, seal entry points with steel mesh, and reblow with fresh product - and we hand you the before-and-after blower-door numbers so you can see the air-sealing improvement, not just smell it.
Our GreenFiber Blown-In Insulation Process

- 1
Call and scheduling. A live person answers 24/7. We book a diagnostic visit with a named technician; you get a text when they’re on the way under Haven Standard: Arrive on schedule.
- 2
Attic inspection and blower-door test. We pressurize the house to measure CFM50 - the cubic feet per minute of air leakage at 50 Pascals - and thermal-image the attic floor to locate bypasses. This gives us a baseline we can compare against after the work.
- 3
Written price and scope. Before any work starts, you receive a flat price, written scope, and written warranty. Haven Standard Clause 1: no exceptions, no “call for a quote.”
- 4
Air sealing first, then insulation. We foam-seal top plates, wire penetrations, chimney chases, and can lights. Only after the blower-door retest shows improvement do we start the GreenFiber blow-in.
- 5
Installation with density verification. We monitor machine settings and spot-check depth with a probe every 100 square feet. For dense-pack walls, we verify cavity pressure and weight.
- 6
Documentation and closeout. You get a Documented Photo Record, the before-and-after blower-door readings, measured R-values, and the 365-Day Done Right Promise in writing. The crew cleans with a magnet sweep for fasteners.
Before
AfterWhat GreenFiber Blown-In Insulation Costs in Georgetown
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| GreenFiber attic top-up (existing R-19 to R-38) | $900 - $1,500 | Attic square footage, access difficulty, whether old insulation needs spot removal |
| GreenFiber full attic replacement (remove and reblow) | $2,200 - $3,800 | Depth of existing material, contamination, deck repairs needed before blow |
| GreenFiber dense-pack wall insulation | $1,600 - $2,800 | Wall cavity height, exterior finish (brick vs. siding), number of stories |
| Air sealing + GreenFiber reblow package | $2,800 - $4,500 | Pre-seal blower-door number, number of can lights, chimney chase complexity |
These are real numbers for Georgetown homes we’ve worked - from 1980s ranch homes near Southwestern University to newer builds in Rancho Sienna. The price goes up if we find roof leaks, active rodent issues, or unsealed ductwork in the attic. It goes down if you’re only topping up good existing insulation with no air-sealing needed. Call (254) 970-2136 for your exact written price - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.
Why Georgetown Homeowners Call Topside Attic Insulation Georgetown for GreenFiber Work

We’ve sealed and insulated over 9,000 homes since 2016, and we don’t treat GreenFiber as generic cellulose with a different bag color. Wes Okafor and our crew know the GreenFiber product line from hands-on work in Georgetown attics - the density settings that actually achieve labeled R-value, the moisture sensitivity of the Low Dust formula in our humid shoulder seasons, and when Sanctuary’s loose-fill characteristics require a different hose technique than standard All Borate.
We’re an independent GreenFiber service provider - not affiliated with or authorized by the manufacturer - which means we source materials based on what your home needs, not a quota. We also install Owens Corning, Johns Manville, Knauf, and other brands, plus Reflectix radiant barrier when the roof deck geometry calls for it. Every job gets the written price first, the blower-door numbers at the end, and the 365-Day Done Right Promise in between. Background-checked, uniformed technicians. Live person on the phone, always.
FAQs
No. GreenFiber’s limited warranty covers product defects in manufacturing, not installation workmanship, so your product coverage remains intact regardless of who installs it. Our workmanship is backed by our own 365-Day Done Right Promise and written warranty, which covers what the manufacturer’s warranty does not - the quality of the install itself. Call (254) 970-2136 if you have a specific warranty document you’d like us to review with you.
We install genuine GreenFiber products - All Borate, Low Dust, Sanctuary, and stabilized cellulose - sourced through standard distribution channels, not proprietary substitutions. If your job calls for a GreenFiber product that’s back-ordered, we’ll show you the equivalent spec from another manufacturer we carry and let you decide. No surprises in the bag.
Topping up is cheaper when the existing insulation is dry, uncontaminated, and hasn’t settled below R-19 - typically $900 to $1,500 versus $2,200 to $3,800 for full removal and replacement. If we find moisture damage, rodent contamination, or compression below R-15 during inspection, removal becomes the only code-compliant option. We tell you which category you’re in before quoting, not after we’ve started. Call (254) 970-2136 for a free inspection and written price either way.
Most GreenFiber attic jobs are scheduled within 3 to 5 business days and completed in one day. Dense-pack wall work or jobs requiring full removal and deck repairs may take two days. Emergency situations - active roof leaks soaking insulation, for example - get same-day or next-day response. When you call (254) 970-2136, a live person will give you the next available slot, not a callback window.
Yes. Every job includes a Documented Photo Record, before-and-after blower-door test results, and measured R-values - the resistance to heat flow - that satisfy most utility rebate programs and buyer inspection requests. We’ve had Georgetown homeowners use our documentation for Austin Energy and Pedernales Electric Cooperative rebates, as well as pre-listing disclosure packets. The report is delivered at job closeout, not available on request later.
