GreenFiber Blown-In Insulation in New Braunfels: What to Know First
We provide independent GreenFiber blown-in insulation service in New Braunfels, with most attic jobs completed in a single day and a written price delivered before any work starts. A typical GreenFiber cellulose top-up or full replacement in a 1,800-2,400 square foot home runs between $1,800 and $3,400 depending on existing depth and air-sealing needs. This page is for homeowners who already have GreenFiber in their attic or walls and need to know whether it can be saved, topped off, or should come out entirely.

How GreenFiber Products Fail - and How We Fix Them
- GreenFiber All Borate Cellulose settling below labeled R-value in humid attics. The product is treated with borate for fire and pest resistance, but in New Braunfels’ spring humidity spikes, cellulose that wasn’t installed to proper settled density can compress and drop from R-38 to R-26 or lower within five to seven years. We measure existing depth with a ruled probe, calculate current R-value against the original bag count, and either add to reach target depth or remove and reinstall at correct density.
- GreenFiber Sanctuary blown-in fiberglass bridging over ceiling joists. This fiberglass product is lighter than cellulose and can create voids where it spans across joist bays rather than filling them, especially in attics with irregular framing common in Canyon Lake-area builds from the 1990s. We break bridged sections by hand and use a slower blower speed to ensure complete cavity fill, then verify with thermal imaging.
- GreenFiber stabilized cellulose losing borate treatment potency in leaky attics. When attic air leaks pull humid outside air through the insulation, the borate compound can leach out over time, reducing both fire resistance and pest deterrence. We always complete air sealing of top plates, can lights, and plumbing penetrations before adding or replacing GreenFiber, then run a blower-door test to confirm the envelope is tight enough to preserve the treatment.
- GreenFiber dense-pack wall insulation sagging in balloon-framed or tall wall cavities. In older homes near the New Braunfels historic district, two-story wall cavities without fire blocking can see dense-pack cellulose settle toward the bottom, leaving a cold zone at the top plate. We drill and re-densify from the interior or exterior depending on siding type, using a higher-pressure hose setup and spot-checking with a density probe every fourth cavity.
- GreenFiber installed directly over unsealed recessed can lights. This is an installation error, not a product defect, but we see it constantly in homes where insulation was added as a quick flip upgrade before sale. The hot fixture creates a convection loop that dries and disperses cellulose, creating a donut-shaped void. We pull back the affected area, install fire-rated covers or LED retrofits as appropriate, seal with fire-stop caulk, then reinstall GreenFiber to proper depth.
Our GreenFiber Blown-In Insulation Process
- 1
Call and schedule. A live person answers, notes your GreenFiber product type if known, and books a site visit. You’ll get a text when the technician is en route.
- 2
Attic inspection and blower-door test. We run a pressurization diagnostic - a blower-door test that measures CFM50, or cubic feet of air leakage per minute at 50 pascals of pressure - to establish your home’s baseline. We photograph existing GreenFiber depth, condition, and any air bypasses.
- 3
Written scope and price. Before any work starts, you receive a flat price, written scope, and warranty terms. This is Haven Standard Clause 1: no exceptions.
- 4
Air sealing first, then insulation. We seal top plates, wire and pipe penetrations, can lights, and chimney chases with appropriate fire-rated materials. The blower-door test is repeated to verify reduction.
- 5
GreenFiber installation or top-up. We use OEM-specified GreenFiber product or, if you prefer, compatible aftermarket cellulose or fiberglass from our multi-brand inventory. Installation density matches or exceeds manufacturer spec for your climate zone.
- 6
Final test, photo record, and documentation. A post-job blower-door test gives you printed before-and-after numbers. You walk away with a Documented Photo Record, written warranty, and our 365-Day Done Right Promise.

| GreenFiber + full attic air sealing with blower-door verification | $3,200 - $5,000 |
What moves the price: existing depth and density, accessibility (steep roof pitch or limited scuttle opening), whether removal is required, and the extent of air sealing needed. We also provide a Free Second Opinion on any written estimate you’ve already received.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for GreenFiber Work
We’re an independent GreenFiber service provider - not affiliated with or authorized by the manufacturer - which means we work on what your home actually needs, not what a brand protocol prescribes. Wes Okafor and our crew have handled GreenFiber jobs from the River Road corridor near the Guadalupe to newer subdivisions off FM 306, and we keep Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and Reflectix in stock when a different material makes more sense for the application.
Every job gets the Haven Standard: written price first, documented photo record at the end, and before-and-after blower-door numbers you can file with your closing paperwork. The 365-Day Done Right Promise means if the CFM50 doesn’t hold or the insulation settles unevenly, we return and correct it. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
FAQs
No. GreenFiber’s product warranty covers manufacturing defects, not installation, and remains valid regardless of who installs or services it. Our work carries its own 365-Day Done Right Promise with written terms delivered before we start. Call (830) 243-6352 if you’d like us to review any existing warranty paperwork with you.
We can source current GreenFiber All Borate or Sanctuary lines to match, though cellulose color varies slightly by production batch. For top-ups, we typically blend new material across the entire attic surface to avoid visible layering. If appearance matters for a future home sale, we note that in the written scope. Call for a free estimate and we’ll show you sample material.
Topping off is cheaper upfront - usually 40 to 60 percent less than full removal - but only makes sense if the existing material is dry, pest-free, and hasn’t compressed below R-20. We probe and test during inspection, then give you both options in writing. In New Braunfels’ climate, we’ve found that cellulose installed before 2015 often benefits from removal due to humidity cycling. Call (830) 243-6352 and we’ll assess what you have.
Most attic jobs are scheduled within three to five business days and completed in one day. Dense-pack wall work or full removals with air sealing may take two days. We don’t quote turnaround times we can’t meet. Call to check current availability.
We stock GreenFiber-compatible cellulose and fiberglass blown-in products at our New Braunfels warehouse, along with alternatives from Owens Corning, Johns Manville, and other manufacturers. For specialized GreenFiber orders, lead time is typically two to three business days, not weeks. We’ll confirm material availability when we deliver your written price.
