Demilec Attic Cleaning & Rodent Proofing Nationwide

Demilec Attic Cleaning & Rodent Proofing in Round Rock: What to Know First

We provide independent Demilec attic cleaning and rodent proofing in Round Rock, typically completing most jobs in one to two days with a written price locked before any work starts. Most attic cleaning and rodent proofing jobs in Round Rock homes with Demilec products run between $1,800 and $4,200 depending on contamination level, accessibility, and whether the Demilec insulation can be salvaged or needs full removal and replacement. This page is for Demilec owners in Round Rock neighborhoods like Behrens Ranch, Fern Bluff, and Forest Creek who’ve found rodent damage, droppings, or compressed insulation and want a crew that understands how Demilec’s open-cell and closed-cell formulations behave differently during cleanup.

How Demilec Products Fail - and How We Fix Them

• Demilec Sealection 500 open-cell compression and rodent nesting. Sealection 500’s lower density makes it attractive to rodents for tunneling, especially in Round Rock’s clay-heavy attics where summer heat drives pests upward. We remove contaminated sections, sanitize the substrate, and reinstall only after full exclusion sealing - never over unsealed penetrations.
• Demilec Heatlok HFO High Yield closed-cell delamination from rodent urine. Heatlok’s rigid closed-cell structure doesn’t absorb urine like open-cell, but the surface film degrades with prolonged exposure, creating off-gassing and R-value loss. We spot-remove affected areas, treat with enzyme-based decontamination, and patch with matching HFO formulation to maintain thermal continuity.
• Demilec Heatlok XT spray foam shrinkage around top plates creating bypasses. XT can pull away from framing in the temperature swings common to Williamson County attics, creating gaps that rodents exploit and conditioned air escapes through. We cut back compromised sections, reseal with compatible foam, and verify with blower-door testing - a pressurization reading that shows, in one number, how much air your building envelope is losing.
• Demilec Agribalance (legacy open-cell) dust and particulate saturation. Discontinued but still present in many Round Rock homes built 2012-2018, Agribalance degrades into respirable particles when disturbed by rodent activity. We use HEPA-contained removal, negative air pressure during extraction, and full PPE protocols - the documentation shows particle counts before and after.
• Demilec Two-Component Pour Foam in knee walls and dormers - rodent highway creation. The rigid pour foam in finished attic spaces doesn’t flex with seasonal framing movement, cracking at corners where rodents enter. We remove compromised pour foam, install mechanical exclusion at all entry points, and replace with properly sequenced air sealing and insulation.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Call and scope. A live person answers (737) 259-7528 24/7. We schedule a site visit, and Wes Okafor or a senior tech arrives with a camera, moisture meter, and respirator - not a clipboard and a sales pitch.
2. 2
   Documented assessment. We photograph every contaminated area, identify your Demilec product line by visual inspection and density testing, and note any warranty documentation you have. You receive a written price before any work starts - Haven Standard Clause 1.
3. 3
   Exclusion first. Seal the leaks first. The insulation has nowhere to go until you do. We find and mechanically seal all rodent entry points - soffit gaps, roof returns, plumbing penetrations - with galvanized steel mesh and polyurethane sealant rated for Demilec contact.
4. 4
   Contained removal and decontamination. HEPA-filtered negative air machines run continuously. Demilec foam is cut and bagged per Warrick County landfill requirements for spray foam waste. Substrates receive enzyme treatment and antimicrobial application.
5. 5
   Replacement and verification. We reinstall with Demilec-compatible materials or your preferred alternative (we also service Reflectix systems). On applicable jobs, we run blower-door tests before and after so you see the CFM50 change in writing.
6. 6
   Documentation delivery. You receive a Documented Photo Record, written warranty, and 365-Day Done Right Promise - if it’s not done right, we make it right.

What Demilec Attic Cleaning & Rodent Proofing Costs in Round Rock

Price movers: attic square footage, roof pitch (steeper = more labor), whether the Demilec is open-cell or closed-cell, and how many rodent entry points need mechanical exclusion. Round Rock’s older homes in downtown neighborhoods often have multiple roof layers and confined scuttle holes that add time. We don’t charge extra for the Documented Photo Record or the written scope - both are included. Call (737) 259-7528 for an exact quote; estimates are free and come with a written price before any work starts.

Why Round Rock Homeowners Call Topside Attic Insulation Round Rock for Demilec Work

We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve cleaned and restored Demilec-insulated attics across Round Rock long enough to know the difference between Sealection 500 and Heatlok HFO by touch and density. Wes Okafor’s crew has served Behrens Ranch to Fern Bluff since before the 2021 freeze, and we’ve documented every job with before-and-after photos and blower-door numbers when applicable. The 365-Day Done Right Promise applies to all Demilec work, and we carry materials from Demilec, Owens Corning, Johns Manville, and others - no proprietary lock-in means you get what’s right for your attic, not what moves our inventory. Calls are answered by a live person 24/7, and we offer a Free Second Opinion on any written estimate you bring us.
