How Demilec Products Fail – and How We Fix Them

Demilec makes solid products, but Austin’s heat and humidity push every spray foam to its limits. After years in attics from Mueller to the Hill Country edges, here’s what we actually see:

• Heatlok HFO shrinkage and pull-away. Heatlok HFO is Demilec’s closed-cell line, and in Austin attics that hit 130°F plus, older batches can shrink slightly from framing. You’ll see hairline gaps at studs and top plates. That gap kills the air seal and lets attic air pour in. We remove the compromised sections, not the whole attic, when the surrounding foam is still sound.
• Sealection 500 off-ratio stickiness. Sealection 500 is Demilec’s open-cell product. When installers push a rig too hard on a hot afternoon, the A and B sides go off-ratio and the foam never fully cures. It stays tacky for years, collects dust, and smells faintly sweet. That’s a full removal and re-insulation, not a patch job.
• Moisture entrapment behind Demilec foam. Open-cell Demilec absorbs water like a sponge if a roof leak develops. You won’t see the leak through the foam. You’ll smell mildew first, then notice the foam darkening. By the time it’s visible, the sheathing behind it is usually soft. We pull the wet foam, expose the deck, and let it dry before anything new goes in.
• Rodent and squirrel damage in Demilec open-cell. Austin squirrels love open-cell foam. They tunnel through Sealection and Heatlok Soy in a weekend. We’ve pulled foam from Mueller bungalows where critters had carved nesting cavities three feet deep. Removal clears the tunnels so we can seal entry points and re-insulate with a material that’s less inviting.
• Homeowner-applied Demilec kits gone wrong. Demilec sells DIY kits, and we get the aftermath. In Austin, the big failure is spraying open-cell in an unconditioned attic without upgrading ventilation first. The foam holds moisture, humidity spikes, and the homeowner’s got a musty ceiling six months later. We remove the foam and correct the ventilation before anything else.

Our Demilec Insulation Removal Process

Here’s how a Demilec removal goes with us, step by step:

1. 1
   Call and square footage. You call (361) 321-0817, we ask for your attic’s square footage and which Demilec product you have, if you know it. Chase Whitaker’s rule applies here: tell us your square footage and you’ll get a real number, no runaround.
2. 2
   On-site inspection and written price. A background-checked, uniformed technician shows up at a live, trackable time. We test foam adhesion, check moisture readings behind open-cell, and give you a written price before any work starts. Not a range, not an estimate. The price.
3. 3
   Containment and negative air. Spray foam removal makes dust, and we don’t let it into your living space. We seal off the attic access, run a HEPA-filtered negative air machine, and protect the path from door to attic with floor cover.
4. 4
   Mechanical removal, not just scraping. Closed-cell Demilec like Heatlok HFO needs more than elbow grease. We use oscillating multi-tools and foam saws to cut sections out cleanly. Open-cell comes out faster with scrapers and vacuum collection. The method matches the foam, not what’s easiest for us.
5. 5
   Waste removal and cleanup. Every bag of foam leaves the property the same day. We vacuum dust from joists and decking and leave the attic cleaner than we found it. You’ll get before-and-after photos of the empty attic.
6. 6
   Post-removal recommendation and written guarantee. Once the Demilec is out, we give you a straight recommendation for what goes back in, whether that’s rockwool, cellulose, or a different spray foam from our eight-brand lineup. Every job gets our 365-Day Done Right Promise in writing, and a free second visit if anything’s not right.

What Demilec Insulation Removal Costs in Austin

Demilec removal in Austin isn’t flat-rate. The foam type, depth, and accessibility all move the number. Here’s what we typically see:

• Partial Heatlok HFO removal (shrinkage repair): $800 to $1,500 for isolated sections, depending on how much framing is exposed.
• Full open-cell removal in a 1,200-square-foot attic: $2,200 to $3,800. Sealection 500 and Heatlok Soy come out faster than closed-cell, which helps.
• Full closed-cell removal in a 1,200-square-foot attic: $3,000 to $4,600. Heatlok HFO is dense and stubborn, and the labor reflects that.
• Moisture-damaged Demilec removal with deck drying: $2,800 to $5,000+, since we’re removing foam, exposing sheathing, and often finding rot that needs a carpenter’s attention.

Depth, attic height, and whether we’re hauling bags down a pull-down stair or a full staircase all move the price. Call (361) 321-0817 with your square footage and we’ll give you an exact written quote. Free estimates, no door-step surprises.
