Demilec Blown-In Insulation in Burbank: What to Know First

We install, top up, and repair Demilec blown-in insulation throughout Burbank, typically completing most jobs in a single visit. Cost for a Demilec blown-in job here runs $1.45 to $3.10 per square foot depending on depth, access, and whether we’re topping up an existing cavity or filling from scratch. If your attic insulation has settled or your walls feel hollow, call (747) 837-5834 and a live person answers, 24/7, never a voicemail.

This page is for Burbank homeowners who have Demilec insulation products, or are considering them, and want a crew that actually understands how these materials behave in Southern California attics and walls. We’re an independent Demilec service provider, not a factory-authorized shop, which means we tell you the unvarnished truth about repair versus replace.

Key Takeaways

  • Demilec blown-in work in Burbank costs $1.45 to $3.10 per square foot, most jobs done in one visit.
  • Demilec’s Heatlok HFO and Sealection 500 are closed-cell spray foams; blown-in Demilec jobs in Burbank are usually top-ups over existing Demilec foam or cavity fills in older framed homes.
  • Settling, UV degradation at attic access points, and rodent damage are the three failure modes we see most in Burbank.
  • We’re independent, fully licensed and insured, and every job carries our 90-Day Done Right Promise.

How Demilec Products Fail - and How We Fix Them

  • Settled foam that no longer fills the cavity. Demilec’s Heatlok HFO and older Heatlok Soy 200 are closed-cell foams that rarely settle on their own, but in Burbank homes from the 1940s through 1970s, we regularly find foam that was sprayed over old fiberglass or cellulose that has settled underneath. The foam shell holds, the fill below drops, and the wall cavity becomes an air channel. Fix: we dense-pack blown-in cellulose or fiberglass into the void behind the foam, restoring the actual thermal barrier without tearing out the original Demilec material.
  • UV-brittled foam at attic hatches and knee-wall tops. Demilec foam exposed to direct sunlight, even through a roof vent or an unshaded attic window, gets chalky and crumbly within three to five years. We see it constantly in Burbank attics with south-facing vents. The crumbled foam loses its air-sealing ability. Fix: remove the degraded inch or two, then re-cover with blown-in insulation to restore the R-value and prevent further UV exposure.
  • Rodent tunnels through the foam layer. Burbank’s older Magnolia Park and Chandler Park neighborhoods have mature trees and plenty of roof rats. They chew through Demilec foam like it’s butter. What looks like a few holes from the attic side is usually a network of tunnels you can’t see until removal starts. Fix: full removal of the compromised sections, rodent proofing, and a fresh blown-in fill. We do all three under one roof.
  • Open-cell used where closed-cell was needed. Demilec’s Sealection 500 is open-cell, great for sound but useless against water. In Burbank’s occasional heavy winter rains, we’ve opened walls where open-cell was sprayed against a weather-exposed rim joist and wicked moisture for years. The material degrades into a damp, compacted mass. Fix: cut out the damaged area, correct the water path, and fill with blown-in or dense-pack material appropriate for the exposure.
  • Top-ups over Demilec’s competitor lines. Many Burbank homes have a blend of brands up there, Demilec over Owens Corning, or CertainTeed over old Demilec foam. Nobody tagged it. We identify what’s actually in your attic, test for settling, and blow in the right product to bring everything up to current Burbank code minimums for attic insulation, which is R-38 in most cases.

Our Demilec Blown-In Insulation Process

  1. 1
    We answer the phone and ask the right questions. You talk to a person, not a call center. We ask about your home’s age, where the drafts are, and whether you’ve had any foam work done before. That gives us a working theory before we ever set foot in your attic.
  2. 2
    We inspect, not estimate blind. Neil Ashford or one of our senior techs heads into the attic or exterior wall cavity with a moisture meter and a borescope. We’re looking for exactly what’s up there: Demilec foam condition, settling, rodent sign, air-sealing gaps around can lights and plumbing penetrations.
  3. 3
    We give you a straight quote. Upfront pricing, line by line. No “we’ll see what we find and bill you later.” You know the cost before we start the blower.
  4. 4
    We do the work same-day in most cases. Removal of degraded material if needed, air sealing where it matters, then blown-in fill to the specified depth. We use quality OEM or equivalent materials, and we never void your existing Demilec warranty by doing hack work around it.
  5. 5
    We test and document. Before we leave, we check depth with a measuring stick, confirm even coverage, and photograph the finished job. You get a real record, not a pat on the head.
  6. 6
    We back it with the 90-Day Done Right Promise. If the insulation isn’t right, we make it right. Written, not implied.

What Demilec Blown-In Insulation Costs in Burbank

Line-item pricing matters more than a single lump sum, so here’s what we actually quote in Burbank:

  • Blown-in cellulose top-up over existing Demilec foam (attic): $1.45 to $1.90 per square foot
  • Blown-in fiberglass, full attic fill to R-38: $1.80 to $2.50 per square foot
  • Dense-pack wall fill (blown-in, into existing framed walls): $2.10 to $3.10 per square foot
  • Rodent-damaged Demilec removal and replacement: Add $0.60 to $1.10 per square foot for the removal portion
  • Air sealing bundled with any blown-in job: $300 to $800 depending on the number of penetrations

What moves the price: access (a tight 1950s attic costs more than a wide 1990s truss attic), whether removal is needed, and whether we’re dealing with pest damage. Every quote is free. Call (747) 837-5834 and we’ll give you an exact number, not a range with fine print.
