GreenFiber Attic Insulation: The Fort Worth Owner’s Guide
We stock and install GreenFiber attic insulation in Fort Worth, with most full-attic installs running $1,200 – $2,800 depending on square footage and the R-value you’re after. We can usually get a crew out same-week, and homeowners typically discover they need this when the attic suddenly feels humid in summer, the upstairs runs 8 – 10 degrees hotter than downstairs, or the old cellulose has settled flat between the joists. If your GreenFiber insulation has failed, compacted, or gotten wet, we’ll assess it, give you a written price, and handle the full swap.
Which GreenFiber Models This Applies To
GreenFiber sells several blow-in cellulose products, but the two we service most in Fort Worth attics are SANCTUARY (their borate-treated, fire-resistant line) and INS550LD (a dense-pack product common in older homes around Ridglea and Wedgwood). The fastest way to identify what you have is to look for the manufacturer label on the side of your attic access or on a paper receipt stapled near the scuttle hole. If the label’s gone, we measure the settled depth and check the fiber consistency to match it properly. One compatibility gotcha: GreenFiber cellulose can’t just be topped off with any blown fiberglass and call it good. Cellulose and fiberglass have different settling rates and air-sealing behavior. If your attic already has GreenFiber, we match it with GreenFiber, not whatever’s on the truck. As an independent Fort Worth service provider, we’re not affiliated with GreenFiber, but we install their material because it holds up well against Texas heat when applied correctly.
Signs Your GreenFiber Attic Insulation Is Failing
- Upstairs rooms won’t hold temperature. Cellulose settles over time, and in Fort Worth’s summer heat the top layer can compact enough to drop R-value by 25 – 30% in the worst spots. That means your AC runs longer just to keep the second floor bearable.
- You can see the joists. After 10 – 15 years in a hot attic, GreenFiber can settle below the top of your ceiling joists, leaving bare wood exposed. That’s thermal bridging, and it’s the clearest visual sign you need a top-up or full re-blow.
- A musty smell upstairs after rain. This usually points to a roof leak that soaked the cellulose. Wet GreenFiber clumps, loses its loft, and can hold moisture against your framing. We don’t top off over wet insulation. It gets removed first.
- Utility bills climbing each July. If your summer usage is up but your thermostat setting hasn’t changed, your attic insulation is likely underperforming. We see this a lot in homes around Northside and Handley where the original blow-in was done in the 1990s.
- Drafts or uneven temps in winter. GreenFiber does a good job slowing airflow when installed at proper density. Once it thins out, cold air sneaks through, and a January cold snap in Fort Worth makes that obvious fast.
Replacement Cost & What’s Included
Installed GreenFiber attic insulation in Fort Worth usually falls between $1,200 and $2,800 for a standard 1,200 – 2,000-square-foot attic, based on the R-value you need (R-38 is common for retrofits here, but R-49 is what we recommend for newer builds). Blow-in GreenFiber runs about $0.90 – $1.60 per square foot installed, including removal of failed material, air-sealing around can lights and top plates, and the full re-blow. Smaller top-up jobs where the existing insulation is still dry and sound start around $450 – $900. Every quote includes removal of old material if needed, equipment setup, the GreenFiber product, and cleanup. You get a written price before anything starts, a written 365-day workmanship guarantee, and photo confirmation of the finished depth and coverage. No door-step price changes, no vague line items.
DIY or Call Us?
You can check for settling yourself: climb up in the attic with a flashlight and look for exposed joists, dry dusty patches, or wet clumps near the eaves. But blowing GreenFiber properly is not a weekend rental job. The equipment from a big-box store throws at lower pressure than professional machines, which means the cellulose doesn’t fluff to its rated depth, and you’ll wind up with uneven coverage you can’t see under your feet. Plus, working in a Fort Worth attic in July or August is genuinely dangerous, and an unevenly dried product can settle in two years to less R-value than what you removed. Call (817) 730-5474 and we’ll send someone out to measure what’s up there and show you the numbers. Good insulation shouldn’t be a mystery; let me just show you the numbers.
FAQs
GreenFiber cellulose holds its R-value for 20 – 30 years in a dry, properly sealed attic, but Fort Worth’s heat cycles can accelerate settling, and we typically see meaningful performance drop-off in attics that haven’t been checked in 15 years or more. Our annual or bi-annual depth check catches it before you lose a full summer’s cooling.
If the material is dry and settled but not contaminated, we can top off over it with matching GreenFiber to bring the depth back to spec, which is the lower-cost fix. If it’s wet, moldy, or rodent-soiled, it comes out before anything new goes in. Call (817) 730-5474 and we’ll tell you which path applies after one attic walk-through.
Most Fort Worth attic replacements are done in a single day. Removal of failed material adds a few hours, but the full job typically goes from start to clean-and-photo in four to eight hours depending on attic size and access.
We keep GreenFiber SANCTUARY and INS550LD on our trucks along with Reflectix radiant barrier for supplementing hot Fort Worth attics. That means same-week scheduling and no week-long wait for product to arrive. We carry it because it’s what we’d spec for our own attics, and we don’t substitute it without a written price and your sign-off first.
