Demilec Blown-In Insulation in Georgetown: What to Know First
We provide independent Demilec blown-in insulation service in Georgetown, typically completing attic top-ups and dense-pack wall jobs in one day with a written price delivered before any work starts. Most Demilec blown-in cellulose or fiberglass jobs in a Georgetown home this size run between $1,800 and $4,200 depending on attic square footage, existing R-value, and whether the air sealing has already been addressed. We are not affiliated with or authorized by Demilec; we are an independent service provider who sources materials from Demilec, Owens Corning, Johns Manville, Knauf, and other manufacturers with no proprietary lock-in. Call (254) 970-2136 for a free estimate with a written scope and warranty delivered before anyone lifts a tool.
How Demilec Products Fail - and How We Fix Them
- Demilec Sealection 500 open-cell spray foam shrinkage at top plates. In Georgetown’s 100°F+ summer attics, this series can pull away from framing members as it ages, creating a convection channel that renders any blown-in top-up nearly useless. We remove the compromised foam, reseal with compatible two-part closed-cell, then blow cellulose to the specified depth.
- Demilec Heatlok HFO High Lift settling in kneewalls. The high lift chemistry can slump in vertical applications after 5-7 years, leaving a gap at the top of the stud bay. We dense-pack with blown fiberglass to restore the thermal boundary without disturbing the remaining HFO.
- Demilec 500 open-cell moisture absorption in Sun City Georgetown homes. The porous structure wicks humidity from vented attics during Georgetown’s March and October shoulder seasons, degrading adjacent blown-in cellulose. We diagnose with thermal imaging, replace affected material, and specify a vapor-smart blown-in system for the repair.
- Demilec Sealection Agribalance density inconsistency at hose terminations. Agribalance’s soy-based content can vary in cell structure, creating soft spots where blown-in top-ups compress unevenly. We map the existing foam with a penetrometer, mark the low-density zones, and adjust our blowing pattern to maintain uniform coverage depth.
- Demilec Eco-Pur contact adhesive failure on ductwork in river corridor homes. Homes near the San Gabriel River corridor see higher humidity that can break down the adhesive bond between Eco-Pur and flex duct, blowing conditioned air directly into the attic. We re-secure with mechanical fasteners, seal with mastic, then blow insulation to bury and protect the repair.
Our Demilec Blown-In Insulation Process
- 1
Call and schedule. A live person answers 24/7. We book a diagnostic visit with a named technician; you get a text when they’re on the way.
- 2
Attic inspection and blower-door test. We pressurize the house to measure CFM50 - the single number showing how much conditioned air you’re losing. We thermal-image the attic, document every penetration, and identify any Demilec foam degradation.
- 3
Written price and scope. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone starts. No exceptions.
- 4
Air sealing first. Seal the holes first. Then we talk about R-value. We foam-seal top plates, can lights, and all penetrations before a single bag of cellulose or fiberglass enters the attic.
- 5
Blown-in installation with real-time depth verification. We blow to the specified R-value - the resistance to heat flow - with depth markers and thermal spot-checks every 100 square feet.
- 6
Post-job documentation. We run the blower-door again, photograph the completed work, and hand you a report with before-and-after CFM50, R-value verification, and duct-leakage numbers from the actual test.
Before
AfterWhat Demilec Blown-In Insulation Costs in Georgetown
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Attic top-up (existing R-19 to R-49) | $1,800 - $2,800 | Attic square footage, accessibility, whether air sealing is pre-done |
| Attic full replacement with removal | $3,200 - $5,500 | Volume of old material, presence of rodent damage, disposal fees |
| Dense-pack wall insulation (Demilec-compatible) | $2,400 - $4,200 | Wall cavity condition, number of stories, interior or exterior access |
| Crawl space blown-in with vapor barrier | $2,800 - $4,800 | Crawl height, existing moisture damage, perimeter sealing needed |
These are real Georgetown numbers based on jobs we’ve completed from River Ridge to Teravista to the older homes near Southwestern University. The price moves up if we find unsealed penetrations that must be addressed first; it rarely moves down because we won’t skip the sealing. Call (254) 970-2136 for your exact written price - estimates are free, and we offer a Free Second Opinion on any competing written estimate.
Why Georgetown Homeowners Call Topside Attic Insulation Georgetown for Demilec Work
We’ve worked attics from Sun City Georgetown to homes backing up to the San Gabriel River corridor, and we’ve learned that Demilec foam systems fail in predictable ways that a generic insulation crew misses. Wes Okafor and our crew have diagnosed these failures since 2016, and we publish before-and-after blower-door numbers on every applicable job so you can verify the performance change you paid for. The 365-Day Done Right Promise applies to all completed work - if it’s not done right, we make it right. We also service Reflectix and other brands, so if your attic has a mix of systems, we don’t need to call in a second contractor. Background-checked, uniformed technicians; calls answered by a live person 24/7; no voicemail loops.
FAQs
No - Demilec’s product warranty covers material defects regardless of who installs or services it, provided the original application met manufacturer specifications. We document the existing foam condition with photos and penetrometer readings to establish whether the failure is material-related or application-related before we start any repair. Call (254) 970-2136 and we’ll review your situation.
Yes - blown cellulose at R-3.7 per inch and blown fiberglass at R-2.5 per inch can both achieve the same total R-value as Demilec foam systems when installed to the correct depth; the critical factor is air sealing, which we complete first. We specify the material based on your attic’s moisture conditions and your performance goals, not brand loyalty.
Look for visible shrinkage at framing edges, dark streaking on the foam surface from air leakage, or temperature stratification in rooms below - but the definitive check is a blower-door test combined with thermal imaging, which we perform during every diagnostic visit. We will not blow insulation over failed foam; it hides the problem and wastes your money.
Spot repair of localized Demilec failure followed by blown-in top-up typically costs 40-60% less than full removal and reinstallation, but only if the remaining foam passes our density and adhesion tests. We give you both prices in writing so you can decide based on actual numbers, not a sales pitch.
Most Demilec-related blown-in attic jobs are completed in one day; dense-pack wall work or full attic removals with Demilec remediation may take two days. We schedule within 48 hours of your call in most cases, and a live person answers the phone 24/7 to book your slot. Call (254) 970-2136 for availability.
