We provide independent Knauf blown-in insulation service in Boerne, with most attic jobs completed in one day and a written price delivered before any work starts. Most Knauf blown-in fiberglass or cellulose installations in a typical Boerne home run between $1,800 and $3,400 depending on attic square footage, existing insulation condition, and whether air sealing is needed first.

This page is for homeowners who already have Knauf insulation in their attic or walls and need topping off, replacement, or a new install with a product they trust. We are not affiliated with or authorized by Knauf. We are an independent Knauf service provider with no proprietary product lock-in, and we also work with Owens Corning, Johns Manville, Rockwool, and other brands including Reflectix.

How Knauf Products Fail - and How We Fix Them

• Knauf Jet Stream Ultra fiberglass settles below labeled R-value in high-humidity attics. The product specs assume stable moisture, but Boerne’s spring humidity spikes and fall temperature swings create condensation cycles that compress loose-fill fiberglass over 5-7 years. We measure settled depth with a ruled probe, calculate the actual R-value loss, and blow new Jet Stream Ultra to the corrected depth rather than the labeled bag count.
• Knauf Ecobatt (dense-packed in walls) develops voids around electrical boxes and plumbing chases. The friction-fit packing loosens where trades have cut access holes, creating thermal bypasses we spot with infrared during our pre-job walk. We pull back the affected cavity fill, seal the penetration with fire-rated caulk or foam, then re-dense-pack to the original 3.5 lb/ft³ target density.
• Knauf Insulation Attic Access blown-in shows wind-washing at eaves in homes with marginal soffit venting. The lightweight fiberglass blows sideways under ridge-vent suction, leaving bare patches above the top plate. We install proper baffles first, then blow to a uniform depth with depth markers every 300 square feet so the homeowner can verify coverage without crawling through insulation.
• Knauf cellulose (NatureBlow) cakes after rodent activity or roof leaks. The boric acid fire retardant doesn’t prevent compression from moisture or nesting, and caked cellulose loses both R-value and fire resistance. We remove the affected material with a vacuum truck, sanitize the deck, repair the entry point or leak source, then blow fresh NatureBlow to the specified weight per bag.
• Knauf blown-in over unsealed top plates leaks conditioned air straight into the attic. This isn’t a product defect; it’s an installation sequence error we see repeatedly in Boerne’s 1990s-2010s subdivisions. We never blow insulation over an unsealed attic floor. Our crew runs a bead of acoustical sealant along every top plate, wire penetration, and can-light housing before the first bag is opened. Seal the envelope first. Then fill it.

Our Knauf Blown-In Insulation Process

1. 1
   Call and schedule. A live person answers 24/7. We book a site visit, not a sales pitch.
2. 2
   Attic inspection and blower-door test. We pressurize the house to 50 pascals and record the CFM50 reading - a single number that shows how much conditioned air your envelope is losing. Wes Okafor has run this test on thousands of homes and hands you the printed report in pascals, not promises.
3. 3
   Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No exceptions.
4. 4
   Air sealing first. Top plates, can lights, plumbing stacks, wire penetrations - sealed with appropriate materials before insulation touches the attic floor.
5. 5
   Knauf product installation. We blow to corrected depth (not bag count), install depth markers, and photograph coverage for your Documented Photo Record.
6. 6
   Final blower-door test and cleanup. We measure again, print the before-and-after comparison, and leave the attic cleaner than we found it. The 365-Day Done Right Promise applies from this moment.

What Knauf Blown-In Insulation Costs in Boerne

These ranges reflect what we see in Boerne’s typical 1,500-2,500 square foot homes, including the older ranches near the Cibolo Nature Center where stack-effect air leakage was eating through cooling bills before a single batt ever went in. Every job gets a written price before work starts. Call (830) 529-7780 for your exact number - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.

Why Boerne Homeowners Call Topside Attic Insulation Boerne for Knauf Work

We’ve sealed and insulated 9,000+ homes since 2016, every one with a written price first and a documented record at the end. Our background-checked, uniformed technicians know Knauf’s product lines specifically - they carry the density specs for Jet Stream Ultra and NatureBlow on their tablets, not just generic blown-in charts. The before-and-after blower-door numbers we publish on every applicable job let you verify the air-sealing result in a single figure, not a feeling.

Because we source from multiple brands including Reflectix, Owens Corning, and Johns Manville, we have no incentive to push one product over another. If Knauf is the right fit for your attic, we say so. If another material performs better for your specific geometry and budget, we say that too. The 365-Day Done Right Promise covers either way - if it’s not done right, we make it right, backed by the written scope and warranty you received before anyone started.
