Knauf Blown-In Insulation in Schertz: What to Know First
We provide independent Knauf blown-in insulation service in Schertz, with most attic jobs completed in a single day and pricing put in writing before any work starts. A typical Knauf blown-in cellulose or fiberglass top-up in a Schertz home runs between $1,800 and $3,400 depending on existing depth, attic square footage, and whether the air sealing has been addressed first. Call (830) 402-5240 for a free estimate with a written price delivered before we lift a tool.
This page is for homeowners who already have Knauf insulation in their attic or walls and need to add to it, replace it, or fix a performance problem. You’ll learn which Knauf lines we see most often in Schertz, how the local climate affects them, and what documentation you’ll walk away with.
How Knauf Products Fail - and How We Fix Them
- Knauf Jet Stream Ultra blown-in fiberglass settles below labeled depth in Schertz’s heat-cycling attics. The 140°F summer peak temperatures in Sedona subdivision attics accelerate compression. We measure existing depth with a calibrated depth stick at 10 points, calculate the shortfall against the bag label’s settled thickness, and blow to true R-38 or R-49 - not bag-count - with a post-install photo log of every stick reading.
- Knauf InsulSafe SP loose-fill fiberglass bridges over recessed can lights that were never properly air-sealed. The insulation creates a thermal blanket over a live air leak, producing ghosting on the ceiling below. We pull back the SP, seal the can-light housing with fire-rated covers and caulked top plates, then reblow - because the attic doesn’t care how thick the insulation is if the air is still moving through it.
- Knauf Ecobatt dense-pack wall insulation slumps in balloon-framed walls common to 1980s Schertz builds. The product needs cavity pressure above 3.5 lbs per cubic foot to hold in vertical walls; original installers often blew at attic-fill density. We drill-and-fill at proper dense-pack pressure, verify with a wall-cavity density probe, and note the reading on your written scope.
- Knauf cellulose treated with borates shows elevated moisture readings after roof leaks in Schertz’s spring storm season. The borate fire retardant is hygroscopic; once wetted, it clumps and loses R-value. We remove the compromised material, document the cavity condition with photos, dry the space if needed, and reblow with fresh product - never over existing wet pack.
- Knauf Jet Stream Ultra bags stored in unconditioned Texas garages harden before installation. The resin binder reactivates in heat and humidity, creating lumps that jam the blower hose and produce uneven coverage. We source fresh stock from authorized distributors with verified lot dates, and we reject any bag showing pre-hardening - a $40 bag is cheaper than a callback.
Our Knauf Blown-In Insulation Process
- 1
Call and scheduling. A live person answers. We book a site visit, and you get a text when Wes Okafor or your named technician is en route.
- 2
Pre-work inspection and blower-door test. We pressurize the house and record the CFM50 reading - the single number that shows how much conditioned air your envelope is losing. In Schertz homes built 1995-2010, we typically see 3,500-5,500 CFM50 before any sealing work.
- 3
Air sealing before insulation. Top plates, wire and pipe penetrations, chimney chases, and can lights get sealed with fire-rated foam, caulk, or rigid covers. We never blow Knauf product over an unsealed attic floor.
- 4
Material selection and installation. We match the Knauf line to your need - Jet Stream Ultra for open attic floors, Ecobatt dense-pack for walls, InsulSafe SP for top-ups. OEM Knauf or equivalent-spec alternative; we explain the choice and note it on your written scope.
- 5
Post-install verification. Depth-stick photo log, thermal imaging scan for gaps, and a second blower-door test on applicable jobs. You get printed documentation: before-and-after numbers, photos, and the completed scope.
- 6
Written price settled, 365-Day Done Right Promise activated. Under Haven Standard: Have it in writing. You already have the price; now you have the warranty document too.
What Knauf Blown-In Insulation Costs in Schertz
Most Knauf blown-in insulation jobs in Schertz fall in these ranges based on what we’ve written for homes in the area:
- Attic top-up (existing R-19 to R-38, Knauf Jet Stream Ultra): $1,800-$2,600
- Full attic replacement, air seal + blow to R-49: $3,200-$4,800

- Insulation removal (wet/compromised Knauf cellulose): $1.20-$1.80 per square foot
What moves the price: attic square footage, existing insulation condition, accessibility (vaulted ceilings add labor), and whether air sealing is needed first. We also carry Reflectix and other brands if your job benefits from a hybrid approach.

FAQs
Does using an independent Knauf service provider void my warranty?
No. Knauf’s product warranty covers manufacturing defects and is not contingent on who installs it, provided the installation meets their published density and coverage specifications. We install to those specs and document depth, density, and coverage on your written scope so any future claim has supporting evidence. Call (830) 402-5240 if you have a specific warranty concern - we’ll review it with you.
Can you match my existing Knauf insulation, or will the new material look different?
We can match the Knauf product line; exact color match varies by lot and age, since Jet Stream Ultra and InsulSafe SP fade slightly in Texas attics over years. For top-ups, we typically blow the matching line and note the lot number on your scope. For visible areas or partial repairs, we discuss the cosmetic result before we start. Call (830) 402-5240 for a free estimate.
Is it cheaper to repair settled Knauf insulation or remove and replace it?
Repair - adding a top-up blow - is usually 40-50% less than full removal and replacement, assuming the existing material is dry, uncontaminated, and not compressed beyond recovery. We test for moisture and density during inspection; if the old pack is salvageable, we say so. If it’s compromised, we document why removal is necessary and show you the photos. Estimates are free.
How soon can you complete a Knauf blown-in insulation job in Schertz?
Most Knauf attic jobs are scheduled within 3-5 business days of estimate approval and completed in one day. Dense-pack wall work or jobs requiring insulation removal may take two days. We do not manufacture urgency - we give you a real date and arrive on it. Call (830) 402-5240 to check current availability.
Do you stock Knauf parts, or is there a long wait for materials?
We source Knauf Jet Stream Ultra, InsulSafe SP, and Ecobatt through regional distributors with standard 1-2 day lead time; we do not stockpile in a warehouse where heat degrades the binder. For urgent jobs, we verify lot freshness before scheduling. If Knauf lead times stretch, we have Reflectix and other equivalent-spec materials available - we’ll explain the alternative and your choice is documented on the written scope before work begins.
