We’re an independent Knauf service provider, not a manufacturer-authorized dealer. That means we answer to you, not a brand rep. Walt’s Insulation has been doing this work in San Antonio since 2000, and we’ve pulled out more failed Knauf jobs than we can count. This page is for homeowners who need straight answers about removal, replacement, and cost.

How Knauf Products Fail - and How We Fix Them

Knauf makes decent materials, but San Antonio’s heat and humidity expose every weak point. Here’s what we actually see in attics across the city:

• Knauf EcoBatt (fiberglass batt) sagging and thermal drift. In older San Antonio homes, EcoBatt batts lose their friction fit against studs after years of attic temperatures hitting 140°F. The batts slump, leaving air gaps at the top of wall cavities. We remove the failed batts and reinstall with proper mechanical support, or switch to blown-in Knauf Jet Stream if the cavity shape calls for it.
• Knauf Jet Stream loose-fill compaction. Blown fiberglass settles over time, especially in high-traffic attic areas around HVAC units. By the time we’re called, R-value has often dropped from R-38 to the low R-20s. We vacuum out the old material, assess whether the attic needs air sealing, and re-blow to the correct depth for our climate zone.
• Moisture-damaged Knauf insulation from roof leaks or condensation. Fiberglass loses its insulative value when wet and becomes a mold host. We often find this in Alamo Heights and Terrell Hills homes where older venting traps moisture. The fix means removing every damp batt, treating the affected wood, and replacing with new Knauf or Rockwool product after the leak source is fixed.
• Rodent-contaminated Knauf batts and blown-in fiberglass. Rats and squirrels love nesting in fiberglass. Their droppings and urine saturate the material. This is a full removal job with sanitization, rodent exclusion, and fresh insulation. We do this work regularly in older neighborhoods like Monte Vista and Olmos Park where mature trees give rodents easy roof access.
• DIY or poorly installed Knauf insulation that never worked right. We see attics where a previous contractor scattered Knauf loose-fill unevenly, leaving some corners at R-11 and others at R-40. The homeowner paid for comfort and got hot rooms. We remove the uneven mess, correct any venting issues, and install properly.

One thing that separates us from a handyman with a shop vac: we know which Knauf material is worth saving and which needs to go. Sometimes we can top off existing Jet Stream instead of a full removal. Other times, like after a rodent infestation or roof leak, keeping any of it is a health risk. We’ll tell you the truth either way.

Our Knauf Insulation Removal & Replacement Process

Here’s how a typical job goes from the first call to the final walkthrough:

1. 1
   You call, a live person answers. No voicemail maze. We ask a few questions about what you’re seeing: high energy bills, hot rooms, visible droppings, water stains. We schedule a visit.
2. 2
   We inspect the attic. Our tech checks the existing Knauf material’s depth, condition, moisture content, and any signs of pests. We take photos and show you what we found. You see what we see.
3. 3
   We give you a written estimate. It breaks down removal, disposal, any air sealing or sanitizing needed, and the replacement material cost. No vague line items. The price we quote is the price you pay.
4. 4
   Removal day. Our crew vacuums out the old Knauf material using commercial extraction equipment. We protect your home with floor runners and seal off the work area.
5. 5
   Prep and replacement. We address whatever caused the problem first: seal air leaks, fix venting, patch the leak, exclude the rodents. Then we install new Knauf insulation or another brand we carry like Owens Corning, Rockwool, or CertainTeed, matched to your attic’s needs.
6. 6
   Final test and walkthrough. We verify R-value depth with a measuring stick in multiple spots around the attic and show you the finished job before we leave.

Every Knauf removal and replacement job we do in San Antonio is covered by our Done Right Promise: if it’s not done right, we make it right. No runaround. That’s been our policy since 2000, and it’s why we have zero interest in cutting corners.

What Knauf Insulation Removal & Replacement Costs in San Antonio

Pricing depends on three things: how much material is up there, what condition it’s in, and whether you need extras like air sealing or rodent exclusion. Here are real ranges for the jobs we do in San Antonio:

What moves the price: attic access difficulty, depth of existing material, whether you have vermiculite mixed in (which requires special handling), and the R-value you want for the replacement. San Antonio is in Climate Zone 2A, so we typically recommend R-38 to R-49 for attic insulation. We offer a free second opinion on any written estimate and no trip charge inside the service county. Seniors and veterans always get 10% off. Call (866) 751-4428 for an exact quote on your attic.

Why San Antonio Homeowners Call Walt’s Insulation for Knauf Work

We’ve been doing insulation work in this city for over 25 years. Walt Brenner grew up on the north side, not far from Brackenridge Park, and he started this company after watching too many San Antonio homeowners get sold materials and methods that didn’t match the South Texas climate. We’re not a franchise and we’re not a call center. You get a published address, a real license number, and a real owner who still checks on jobs personally.

Every technician who walks into your house is background-checked and uniformed. If we ever find that your Knauf material isn’t the issue and the real fix is a different product, we’ll tell you that too. We install Owens Corning, Rockwool, Icynene, Johns Manville, CertainTeed, Demilec, Knauf, and GreenFiber, plus we service Reflectix radiant barrier jobs. We recommend what’s right for your attic, not whatever brand gave us the best wholesale price that quarter. And when you call, we answer the phone live. Talk to a real person, get a straight answer.
