Call (562) 317-6204

We’re an independent Knauf service provider, which means we install and maintain Knauf fiberglass blown in products but have no corporate affiliation with the manufacturer. That independence works in your favor: we recommend what your attic actually needs, not what a brand rep tells us to push.

This page is for Long Beach homeowners who own homes insulated with Knauf fiberglass, or who are considering it, and want straight answers about performance, failure modes, and real costs. If you’ve got an attic that’s too hot in August or too cold in January, call (562) 317-6204 and we’ll come look.

Key Takeaways

• Knauf blown in fiberglass settles 2-4% over the first few years in Long Beach’s humidity swings, which means attics insulated a decade ago are often under-insulated today.
• We carry Knauf Insulation Jet Stream and Knauf EcoBatt for blown in and batt hybrid jobs, and can match existing R-values precisely.
• Every Knauf job includes a written price before work starts and a 365-day written guarantee.

How Knauf Products Fail, and How We Fix Them

Knauf fiberglass doesn’t rot or attract termites the way cellulose can, but it isn’t failure-proof. After nearly two decades running crews across Long Beach, Bryce Holloway has seen the same failure patterns repeat in attics from Belmont Shore to Bixby Knolls. Here’s what we find most often:

• Settling and compression in Knauf Jet Stream blown in fiberglass. Fiberglass blown in products settle naturally, and Jet Stream is no exception. In Long Beach attics where the original installers blew to minimum code depth back in the 2000s, we often find effective R-value dropped from R-38 to R-30 or lower after 10 to 15 years of humidity cycling and roof heat. The fix is a top-up blow to restore target depth, which we can quote precisely after measuring current depth and density.
• Baffle blockage and poor attic ventilation. Long Beach homes built before 1990 often have soffit vents that got buried when insulation was blown in. When Knauf fiberglass blocks soffit airflow, attic temps climb past 140°F in summer, which accelerates shingle wear and makes the AC work harder. We install or repair baffles on every blown in job, then blow to depth.
• Gaps around recessed lights and chimney chases. In older Long Beach homes, we regularly find Knauf insulation stopped short of recessed can lights because the original installer was worried about fire clearance. Modern LED fixtures still need airflow clearance, but the gap doesn’t need to be a foot wide. Air sealing and proper dam construction around each fixture fixes the thermal leak without creating a hazard.
• Knauf EcoBatt batts used as a patchwork over older blown in. Some homeowners or handymen lay batt insulation over settled blown in material, thinking it solves the problem. It doesn’t; the batts compress the blown in fiberglass underneath and create thermal bypasses at the batt seams. When we see this, we remove the batts, fluff the existing blown in where salvageable, and blow fresh Knauf material to a uniform depth.
• Under-insulated kneewalls in attic bonus rooms. Belmont Shore bungalows and craftsman-style homes in Long Beach often have finished attic spaces where the kneewalls were insulated with thin R-13 batts or left bare. Knauf blown in doesn’t work in vertical wall cavities, so we handle these by dense-packing Knauf JM batts or switching to Knauf Jet Stream in enclosed cavities using the right equipment.

Each of these has a fix, and none of them require tearing out your whole attic. We diagnose first, then quote a written price. No surprises at invoice.

Our Knauf Blown In Insulation Process

Here’s what a Knauf blown in insulation job looks like with our crew, from the first call to the final walkthrough:

1. 1
   Call and schedule. A live person answers at (562) 317-6204, any time. We set a window, and our background-checked, uniformed technicians show up inside it. Not a vague half-day range.
2. 2
   Attic assessment. We measure current insulation depth in multiple spots, check for air leaks, inspect soffit airflow, and look at what type of Knauf product is already in place. We document with photos so you can see what we see.
3. 3
   Written quote. Before any tool comes off the truck, you get a written price covering material, labor, and cleanup. The number you approve is the number on the invoice.
4. 4
   Prep work. We air seal penetrations where needed, install or repair soffit baffles, and protect access areas with drop cloths. If removal of old or contaminated insulation is required, we handle that before blowing new material.
5. 5
   Blow to spec. We blow Knauf insulation to the R-value we agreed on, measured with depth markers during the job so we’re not guessing. Uniform coverage matters more than most homeowners realize; thin spots are where heat moves.
6. 6
   Cleanup and verification. We restore the attic access, clean the work area, and do a final depth check. Then we walk you through what was done and hand you the written 365-day guarantee.

If the work fails within 365 days, you get a free return visit to make it right. That’s the Done Right Promise, in writing, every time.

What Knauf Blown In Insulation Costs in Long Beach

Most Long Beach attic insulation projects run $1,800 to $4,200, depending on square footage, current R-value, and access difficulty. Here’s a breakdown of the common scenarios we quote:

• Top-up blow over existing Knauf (R-30 to R-38): $1,200 to $2,400 for a typical 1,200 to 1,800 square foot attic.
• Full removal and re-blow with Knauf Jet Stream: $3,000 to $5,500, depending on attic size and condition of existing material.
• Air sealing plus blow to R-38: $2,200 to $4,000, including sealing around can lights, attic hatch, and top plates.
• Attic with difficult access or steep pitch: Add $300 to $800 to any of the above.

The big price movers are attic square footage, how much old insulation has to come out, and whether air sealing is needed. Every quote is written, itemized, and good for 30 days. Call (562) 317-6204 for a free estimate, and we’ll come measure.
