GreenFiber Spray Foam Insulation in Fort Worth: What to Know First

We install and service spray foam insulation alongside GreenFiber blown-in products in Fort Worth homes, with most jobs completed in one to two days. Spray foam projects in our area typically run from $1,800 to $6,500 depending on square footage, foam type, and access, and you’ll always have a written price before any material leaves the truck. This page is for Fort Worth homeowners who already have GreenFiber insulation and want to add spray foam for air sealing, or who need spray foam work done in a home where GreenFiber is already present.

How GreenFiber Products Fail – and How We Fix Them

GreenFiber makes cellulose insulation from recycled paper treated with borates for fire and pest resistance. In Fort Worth homes, we see specific issues when GreenFiber and spray foam meet or when GreenFiber has aged in our climate. Here’s what we find on real jobs:

• GreenFiber Sanctuary settles under open-cell foam. GreenFiber’s Sanctuary blow-in line can settle up to 20% over a decade, especially in Fort Worth’s summer attic heat that bakes the cellulose dry. When a previous contractor sprayed open-cell foam over settled Sanctuary, the foam bridges the gap but leaves a void underneath. We remove the compromised section, re-blow to the correct R-value depth, and reapply foam where it belongs.
• Insulmax accumulation against rim joists traps moisture. GreenFiber’s Insulmax line, often used for dense-packed walls, accumulates against rim joists in pier-and-beam Fort Worth bungalows near Fairmount. When someone adds spray foam to the rim joist without clearing the cellulose first, the sandwich traps condensation. We clear the joist bay, check for moisture staining, and apply closed-cell foam directly to the cleaned surface.
• Borates degrade under direct spray foam contact. GreenFiber’s borate fire retardant reacts over time when closed-cell foam is sprayed directly onto untreated cellulose. The foam’s exothermic cure can cause the borates to clump and lose fire resistance. On Fort Worth jobs where this has happened, we remove the contact layer and install a thermal barrier before re-foaming.
• GreenFiber’s stabilized line mixed with old loose-fill creates uneven density. When GreenFiber Stabilized Cellulose is added over older loose-fill from another brand, the density difference shows up once spray foam is applied to the roofline. The uneven substrate means the foam can’t cure uniformly. We map the attic with a thermal camera, identify the density seams, and even out the base before foam goes down.
• Pest intrusion through foam gaps around GreenFiber-baffled vents. GreenFiber’s baffle system at the soffits sometimes leaves a quarter-inch gap that rodents and squirrels exploit in older Fort Worth neighborhoods like Ryan Place. When we spray foam around those baffles, we first seal the gap with closed-cell foam, then verify the baffle channel is still clear so attic ventilation doesn’t suffer.

Every fix above starts with a visual inspection and often a thermal scan. We don’t guess. Neil Barron and the crew walk the attic before anyone opens a spray gun.

Our GreenFiber Spray Foam Insulation Process

Here’s how a typical GreenFiber-to-spray-foam job runs with us in Fort Worth:

1. 1
   Call and schedule. You talk to a live person. We set a time that works around naps and school drop-offs.
2. 2
   Walkthrough with the homeowner. Neil or the lead tech inspects the attic, the existing GreenFiber, and the target area. You hear exactly what product goes where and why.
3. 3
   Written price. Before any work starts, you get the number in writing. Not a range. Not an estimate that grows. The price.
4. 4
   Prep the home. Shoe covers go on at the door. Drop cloths run from the entry to the attic hatch. Furniture near the work area gets covered.
5. 5
   The work. We remove or adjust existing GreenFiber as needed, prep surfaces, apply the right spray foam for the job, and let it cure properly.
6. 6
   Test and clean up. We verify the foam depth with a gauge, check for gaps with a thermal camera, then clean the workspace. You get a photo of the clean area before we leave.

Every job carries the 365-Day Done Right Promise. If something isn’t right, we come back and make it right. No argument, no fine print.

What GreenFiber Spray Foam Insulation Costs in Fort Worth

Spray foam pricing in Fort Worth depends on what you’re doing. Here’s what we typically see:

• Rim joist spray foam in a crawlspace: $900-$1,800 depending on linear feet and access.
• Garage ceiling spray foam, 400 sq ft: $1,200-$2,200.
• Open-cell spray foam roofline, 1,500 sq ft attic: $3,500-$5,500.
• Closed-cell spray foam roof deck, 1,500 sq ft: $5,000-$7,500.
• Small retrofit around GreenFiber baffles or penetrations: $400-$900.

What moves the price: foam type (closed-cell costs more than open-cell), access difficulty, the condition of existing GreenFiber, and whether we need to remove or adjust any existing insulation first. Fort Worth homes with steep roof pitches or tight attic hatches add prep time. You’ll know your exact number before we start, in writing, every time. Call (682) 233-8300 for a free estimate.

Why Fort Worth Homeowners Call Thistledown Insulation Fort Worth for GreenFiber Work

Thistledown is part of the Cedarwell family of independently owned insulation companies, founded in 2003. The name comes from the soft fluff of the thistle, one of nature’s lightest insulators. It’s a reminder of how carefully we work in your home.
