Our Knauf Spray Foam Insulation Process

Every Knauf job in Austin follows the same path, whether it’s a new-build roof deck or a retrofit rim joist. Here’s how it goes.

1. 1
   Call and quick triage. We ask about your space, your current insulation, and what the problem is. If it’s an existing foam issue, we’ll want photos or a quick video call before we schedule.
2. 2
   Site assessment and measurements. We come out, measure square footage and depth, check ventilation and framing, and look at what’s currently in the cavity. You get a written quote before any work is authorized.
3. 3
   Material decision. For Knauf jobs, we match the system to the space. Open-cell for attic roof decks and interior noise control; closed-cell for rim joists, crawl spaces, and areas needing moisture resistance. We’ll tell you the R-value per inch of each option and why we’re recommending one over the other.
4. 4
   Prep and application. We mask off windows and floors, seal gaps, and run the Knauf foam per the manufacturer’s spec for temperature and humidity. Austin heat means we pay attention to substrate temperature – if it’s too hot, foam won’t adhere properly.
5. 5
   Trim, test, and photo proof. We trim excess foam, verify depth and adhesion, and check for voids. You get before-and-after photos sent to your phone, so you can see the actual work even if you weren’t home.
6. 6
   Written guarantee. Every Knauf job gets our 365-Day Done Right Promise in writing. If it’s not right, we make it right. If it fails within a year, the second visit is free. No charge, no argument.

Total time from first call to finished job usually runs three to seven days depending on weather and material availability. Emergency work can move faster.

What Knauf Spray Foam Insulation Costs in Austin

Here are honest numbers for the Knauf spray foam scenarios we see most in Austin homes, from Mueller bungalows to new builds out toward the Hill Country.

• Open-cell roof deck (1,500 sq ft attic): $2,400 to $4,200. This is the most common warm-climate roof deck application.
• Closed-cell rim joist (per 100 linear feet): $900 to $1,800. Includes sealing and moisture barrier benefits.
• Garage ceiling (400 sq ft): $700 to $1,500. Smaller job, but framing and access still matter.
• Retrofit wall cavity (per room, 3 exterior walls): $1,200 to $2,600 depending on stud depth and existing insulation removal.
• Insulation removal plus new spray foam (per attic, moderate size): $1,500 to $3,400 depending on what’s being pulled out and how deep the new foam goes.

What moves the price: square footage, foam depth, whether we’re removing old insulation first, and how tight the access is. Austin crawl spaces in older homes tend to be tight and slow. We factor that in honestly. Call (361) 321-0817 and we’ll give you an exact number before any work starts. Free estimates, no pressure.
