Knauf Blown-In Insulation in Converse: What to Know First
We install and service Knauf blown-in insulation in Converse as an independent Knauf service provider, with most attic jobs completed in one day and pricing put in writing before any work starts. A typical Converse ranch-style home near Foster Road runs between $2,400 and $4,200 for full attic coverage with air sealing, depending on accessibility and existing conditions. We’re not here to sell you insulation over the phone - we’re here to measure what’s actually happening in your attic, seal what leaks, and show you the blower-door numbers that prove it worked.
This page is for homeowners who already have Knauf insulation in their Converse home, or who are comparing Knauf blown-in cellulose or fiberglass against other brands and want to know what specific problems to watch for. Call (830) 420-0953 to schedule a free estimate with written pricing.
How Knauf Products Fail - and How We Fix Them
- Knauf Jet Stream Ultra cellulose settling below labeled R-value in Converse’s heat. The Ultra line is treated with boric acid for fire and pest resistance, but in attics that hit 140°F through a Converse summer, the material can compact 15-20% in the first three years if it was blown at low density to begin with. We find this most often in homes built 2015-2020 near Rolling Ridge Drive. Our fix: remove the settled material, re-blow at the manufacturer’s specified density of 1.6 lbs/ft³, and document the depth with photos at multiple joist bays.
- Knauf Ecobatt fiberglass batts used as a base layer with blown-in on top, creating a thermal sandwich that traps moisture. Ecobatt’s brown binder is plant-based and hydrophilic - meaning it absorbs water vapor - which is fine in dry climates but problematic in Converse’s spring humidity spikes when attic ventilation is marginal. We pull the Ecobatt if moisture readings exceed 18% wood moisture equivalent, air seal the deck, and replace with loose-fill blown-in that doesn’t create a vapor barrier where one isn’t wanted.
- Knauf Insulation Atticat pink fiberglass blown-in installed over unsealed top plates. The Atticat system is a solid product, but we regularly find it blown directly over the gaps where interior walls meet the attic floor - those top-plate penetrations bleed conditioned air at 4-8 CFM50 per linear foot in a typical Converse ranch. We seal every penetration with fire-rated caulk and foam, then re-blow to maintain consistent depth. The numbers will tell you if it worked.
- Knauf dense-pack wall insulation sagging in balloon-framed Converse homes from the 1970s. Older homes near Converse’s original downtown core often have no top plate blocking between stories, so dense-pack cellulose installed from the attic can settle into the wall cavity below, leaving a 2-3 foot uninsulated collar at the top. We diagnose this with thermal imaging from the exterior on a 20°F morning, then re-dense-pack with proper netting or drill-and-fill from the interior if needed.
- Knauf blown-in fiberglass degrading around recessed can lights in post-2010 builds. The EcoFill fiberglass line doesn’t tolerate direct contact with non-IC-rated fixtures - the binder off-gasses and the material mats down, creating a fire hazard and an insulation void simultaneously. We see this in newer subdivisions off FM 1518. Our fix: install proper fire-rated covers or replace with IC-rated LED housings, then re-blow to uniform depth.
Our Knauf Blown-In Insulation Process

- 1
Call and scheduling. A live person answers, or you text us back. We book a 2-hour arrival window - not “morning or afternoon” - and send a text when Wes or a named technician is en route.
- 2
Attic inspection and blower-door test. We pressurize the house to 50 pascals and record the CFM50 reading - the single number that tells us how much air your envelope is leaking. We photograph every top plate, penetration, and existing insulation condition. You get these photos.
- 3
Written scope and price. Before any work starts, you receive a flat price, a written scope of work, and the 365-Day Done Right Promise in writing. This is Haven Standard Clause 1 - no exceptions.
- 4
Air sealing first. We seal all top plates, can lights, plumbing and electrical penetrations, and chimney chases with appropriate fire-rated materials. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
- 5
Knauf material selection and installation. We source from Knauf’s available lines - Jet Stream Ultra, EcoFill, Atticat - based on your attic’s conditions and your preference. No proprietary lock-in; we also stock Reflectix and other brands if Knauf isn’t the right fit for a specific application.
- 6
Post-work blower-door test and documentation. We run the pressurization test again, print the before-and-after report, and add the photos to your job record. You leave with both in hand.
Before
AfterWhat Knauf Blown-In Insulation Costs in Converse
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Attic top-up (existing 6-8″ Knauf, add to R-38) | $1,800 - $2,800 | Accessibility, joist spacing, whether we need to pull degraded material first |
| Full attic removal and replacement with Knauf blown-in | $2,800 - $4,800 | Square footage, contamination (rodent, moisture), air sealing extent |
| Dense-pack wall insulation (Knauf cellulose) | $2,200 - $3,600 | Wall cavity depth, interior vs. exterior access, finish repair responsibility |
| Air sealing + Knauf blown-in (complete envelope) | $3,400 - $5,600 | Pre-seal blower-door number, complexity of penetrations, chimney chase sealing |
These are real ranges for Converse homes we’ve worked on - not teaser prices.

Why Converse Homeowners Call Topside Attic Insulation Converse for Knauf Work

We’ve sealed and insulated over 9,000 homes since 2016, and the ones in Converse keep us honest about heat. Wes Okafor grew up on Chicago’s South Side and learned insulation fundamentals at Kennedy-King College’s building trades program before spending two decades applying that in Texas attics - he knows what 140°F attic air does to a material spec sheet written for 85°F.
Our crew doesn’t guess. Every applicable job gets a before-and-after blower-door test with printed results. Every job gets a Documented Photo Record, included, not available on request. And every job starts with a Written Price Before Any Work Starts - Haven Standard Clause 1. If something’s not right, the 365-Day Done Right Promise means we make it right. Calls are answered by a live person 24/7. No voicemail loops. No callback windows measured in business days.
We work with Knauf, Owens Corning, Johns Manville, Rockwool, and others - no brand lock-in, no preferred dealer status that steers you toward one product. We use what fits your attic.
FAQs
No - Knauf’s product warranty covers manufacturing defects in the material itself, not who installs it. As an independent Knauf service provider, we install to manufacturer density and depth specifications, which preserves any existing material warranty. We document our work with photos and depth measurements so you have proof of proper installation if a claim ever arises. Call (830) 420-0953 if you have a specific warranty concern.
Most Knauf service calls in Converse are scheduled within 48 hours, and emergency situations - like insulation compromised by active roof leaks or rodent infestation - often same-day. We don’t do callback windows measured in business days; a live person answers 24/7 and books a specific 2-hour arrival window. Text us at (830) 420-0953 if you prefer.
Repair is cheaper when the material is dry, uncontaminated, and simply settled - typically $1,200-$2,000 to add density and restore R-value. Remove-and-replace runs $2,800-$4,800 but is necessary when there’s moisture damage, rodent activity, or the wrong product was used initially (like Ecobatt in a humid attic). We inspect, test with a moisture meter, and give you both options in writing before you decide. Call (830) 420-0953 for a free assessment.
Usually yes - Knauf Jet Stream Ultra and EcoFill are readily available through our suppliers. We match density and material type to avoid thermal layering issues. In cases where the original product is discontinued or incompatible with current conditions, we explain the mismatch and recommend the closest appropriate alternative. We don’t blend dissimilar materials without documenting why. Bring us your existing insulation photos or any paperwork from the original install.
We stock Knauf blown-in cellulose and fiberglass in our Converse-area warehouse, along with Reflectix and other brands. Dense-pack applications or specific R-value targets sometimes require a next-day material pull, but standard attic work is loaded on the truck before we arrive. If your job needs something we don’t have on hand, we tell you in the written scope - no surprises after work starts. Call (830) 420-0953 to confirm availability for your specific job.
