How Knauf Products Fail – and How We Fix Them

Knauf makes solid insulation, but San Antonio attics punish any blown in product that isn’t installed to spec. Here’s what we see on Knauf jobs in this market, and what we do about it:

• Knauf Jet Stream Ultra settling below target R-value. Jet Stream Ultra is Knauf’s primary loose-fill fiberglass line, rated for R-30 to R-60 when blown to the correct depth. In San Antonio homes built before the 1990s, we regularly find it blown to only 6 to 8 inches, which nets around R-19 to R-24. The fix is re-blowing to the depth chart on the bag, usually 14 to 17 inches for R-38 in our climate zone. We mark depth sticks before we start so you can see the inches, not just take our word for it.
• Knauf EcoBatt used as a blown in substitute, not a complement. EcoBatt is Knauf’s batt line, and it’s a fine product when it fits the framing. But in older San Antonio attics with irregular joist spacing, batts leave gaps at the edges, and those gaps become thermal bypasses. We pull out the compressed, mouse-chewed batts and switch to blown in Knauf loose-fill so the material actually fills the cavity.
• Moisture-compromised Knauf from roof leaks or HVAC condensation. Loose-fill fiberglass loses R-value when it gets wet, and it doesn’t recover when it dries. In San Antonio’s high-humidity summers, a small roof leak or an uninsulated AC duct sweating in the attic can soak Knauf material before you ever see a stain on the ceiling. We find the water source first, or the new insulation fails the same way.
• Wind-washed Knauf near the eaves. In San Antonio attics with strong soffit ventilation, loose-fill gets pushed back from the eaves by wind, which is exactly where heat pours in during July. We install rafter vent channels and eave baffles so the Knauf stays in place and the airflow stays where it belongs.
• DIY Knauf jobs with no air sealing underneath. This is the most common one. A previous owner rents a blower, blows Knauf over an unsealed attic floor, and wonders why the upstairs is still hot. Insulation slows heat transfer. It doesn’t stop air movement. We seal the top plates, wire penetrations, can-light housings, and attic hatch before any Knauf goes down. Without that, you’re paying to insulate a leaky boat.

Our Knauf Blown In Insulation Process

Here’s how a Knauf job runs with us, from the first call to the final walkthrough:

1. 1
   Call and schedule. A live person answers at (361) 213-9499. You tell us what you’re dealing with, and we schedule a visit. Before our tech arrives, you get their name and photo by text so you know who’s at the door.
2. 2
   Attic inspection and measurement. Our tech measures the existing insulation depth, checks for air leaks, moisture, and ventilation problems, and documents it with photos you can see on the spot.
3. 3
   Written price before anything starts. You get a line-item price for the Knauf material, any removal needed, air sealing, and labor. No verbal quote that changes later. You approve it in writing.
4. 4
   The work. We prep the attic: seal penetrations, install baffles where needed, set depth markers, and blow the Knauf to the R-value we agreed on. No shortcuts on coverage, no skimping at the edges.
5. 5
   Verification and cleanup. We check our depth markers, verify the coverage is even, and clean up so nothing remains but the insulation. You see the finished attic before we leave.
6. 6
   The guarantee. Every Knauf job is covered by our 365-Day Done Right Promise in writing. If something isn’t right, we come back and make it right at no charge.

What Knauf Blown In Insulation Costs in San Antonio

Blown in Knauf pricing in San Antonio runs about $1.10 to $2.30 per square foot for a standard retrofit with R-38, and that range covers most of what we quote. Here’s a breakdown by scenario:

• Basic top-off over existing insulation (R-19 to R-38): $0.80 to $1.40 per square foot.
• Full removal of old, compromised material plus new Knauf to R-38: $2.10 to $3.00 per square foot.
• Air sealing added to the project: $350 to $800 depending on attic size and access.
• Attic hatch insulation and weatherstripping: $180 to $350 as a companion fix.

What moves the price is attic access, ceiling height, whether old insulation has to come out, and whether we’re fixing ventilation at the same time. We give you the written price before anything starts, so there’s no surprise bill at the end. Call (361) 213-9499 and we’ll schedule a time to measure and quote it properly.
