Insulation in Austin, TX
Crawl space encapsulation and vapor barrier work in Austin typically runs $3,500-$7,500 for most homes, with jobs completed in 1-2 days. Austin’s combination of clay-heavy soils, extended humid seasons, and 1980s-2000s tract homes built with minimal ground-floor moisture protection makes this one of the most consequential envelope upgrades a homeowner can make. Call (737) 259-8352 for a written price before any work starts.
We dispatch crews from our Austin office and treat every job under The Haven Standard: written scope, written price, written warranty before anyone lifts a tool, plus a Documented Photo Record when we leave.
Why Austin Homes Are Different
Austin is the only major Texas city with a municipal Energy Conservation Audit and Disclosure (ECAD) ordinance requiring an energy audit - which flags insulation deficiencies - every time a home over 10 years old changes hands. This law, enforced by Austin Energy, creates a uniquely transaction-driven retrofit market that doesn’t exist in Dallas, Houston, or San Antonio. Real estate turnover is a primary insulation demand engine here, and we regularly get called during the option period of a home sale.
The housing stock splits sharply: 1940s-60s bungalows and ranch homes in Allandale, Crestview, and Hyde Park often carry original blown-in fiberglass settled to an effective R-8 or less, while the 1980s-2000s tech-boom tract construction used R-19 or lower in attics when Austin’s energy code was far more permissive. Attic cavities routinely exceed 140°F June through September, and ductwork is almost universally routed through those unconditioned spaces. Winter Storm Uri exposed that Austin homes were engineered almost entirely around shedding heat, with virtually no provision for cold retention, creating a dual-season gap we’re still working through.
Our Main Austin Services
These are the three services Austin homeowners call about most often. Each has its own detailed Austin page if you want to go deeper.
Attic Insulation in Austin
Attic insulation in Austin means dealing with 140°F summer cavities and ductwork that loses conditioned air before it ever reaches the living space. We see the most dramatic returns in older neighborhoods like Hyde Park and Crestview, where original fiberglass has settled to R-8 or below, and in East Austin flips where cosmetic renovation left decades-old insulation untouched beneath new finishes. Every attic job begins with air sealing - we don’t blow insulation over an unsealed attic floor - and ends with a Documented Photo Record. Attic Insulation in Austin
Spray Foam Insulation in Austin
Spray foam insulation in Austin solves a problem specific to this market: ductwork running through 140°F attics loses enormous efficiency, and conditioned-attic spray foam on the roof deck - converting the attic to conditioned space - is often the most cost-effective path to real performance gains. We source materials from Icynene and Demilec, with no proprietary lock-in, and publish before-and-after blower-door numbers on every applicable job. Spray Foam Insulation in Austin
Blown-In Insulation in Austin
Blown-in insulation in Austin is the workhorse upgrade for settled fiberglass in Allandale, Crestview, and the 1980s-2000s subdivisions built during the tech booms. We use Owens Corning and GreenFiber materials, and we never add new blown-in over an unsealed attic floor - that’s Haven Standard practice, not an upsell. The blower-door test before and after shows the actual air-leakage reduction you paid for. Blown-In Insulation in Austin

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Austin
Austin’s clay soils hold moisture year-round, and the 1980s-2000s tract homes that dominate the market were built with minimal ground-floor moisture protection. Crawl space encapsulation and vapor barrier work stops the upward migration of that moisture into floor systems, which is why we treat it as a hard prerequisite for any crawl space insulation - not an upsell. Crawl Space Encapsulation & Vapor Barrier is the foundation of a healthy envelope in this soil and climate.
We see the worst conditions in homes near the Colorado River floodplain and in the clay-heavy east side, where seasonal swelling and contraction cracks the thin vapor barriers original builders installed, if they installed them at all. The result is sagging fiberglass, mold-prone joist bays, and floors that feel cold even when the heat is running.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, visible mold on joists, or a musty smell that rises through floor registers.
What it costs in Austin
A 6-mil to 20-mil vapor barrier installation for a typical Austin crawl space runs $1,200-$3,000 depending on square footage and seam-sealing requirements.
How we do it
We remove debris, grade the soil for drainage, lay overlapping polyethylene sheets with sealed seams, and terminate at foundation walls with mechanical fastening and sealant.
Crawl Space Encapsulation
Signs you need it
Your HVAC ducts run through the crawl space, you have hardwood floor cupping, or your energy bills spike in humid months despite moderate thermostat settings.
What it costs in Austin
Full encapsulation with sealed vapor barrier, insulated walls, and conditioned air supply for a typical Austin home ranges $3,500-$7,500.
How we do it
We seal all vents, install a reinforced vapor barrier across floors and up walls, insulate foundation walls with rigid foam, and add a dehumidistat-controlled dehumidifier sized to the space.
What Crawl Space Encapsulation & Vapor Barrier Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Vapor barrier (6-20 mil) | $1,200 - $3,000 |
| Full encapsulation | $3,500 - $7,500 |
| Encapsulation with dehumidifier | $5,000 - $9,500 |
How long does crawl space encapsulation take in Austin?
Most jobs finish in 1-2 days. Clay soils with poor drainage may need a day of prep grading first. Call (737) 259-8352 for a written scope and timeline - estimates are free.
Will encapsulation help my floors feel warmer?
Yes. Sealing the crawl space stops evaporative cooling under the floor system, which is why Austin homeowners with hardwood over vented crawls report the most noticeable comfort difference.
Radiant Barrier Installation in Austin
Austin attic temperatures routinely exceed 140°F from June through September, and radiant heat transfer from the roof deck to ductwork and ceiling drywall is the dominant cooling load most homeowners never address. Radiant barrier installation reflects that infrared energy back toward the roof deck rather than letting it radiate into the attic space, which is particularly valuable here because Austin’s housing stock was engineered to shed heat, not retain cool air, and ductwork losses in unconditioned attics are severe.
We install more radiant barrier in Austin than in any other market we serve, often in combination with air sealing because a radiant barrier without sealed duct boots and top plates is only half a solution.
Attic Radiant Barrier
Signs you need it
Your attic feels like a furnace by 10 a.m., your HVAC runs continuously on summer afternoons, or your second floor stays 8-12°F warmer than the first.
What it costs in Austin
Radiant barrier installation for a typical Austin attic runs $1,500-$3,500 depending on roof complexity and whether we use foil sheets or spray-applied coating.
How we do it
We staple reinforced aluminum foil to the underside of roof rafters with proper air gaps, or apply a low-emissivity spray coating to the roof deck, always after air sealing is complete.
Radiant Barrier & Ventilation
Signs you need it
Your attic has inadequate soffit or ridge ventilation, you see moisture staining on the roof deck in winter, or your radiant barrier is trapping humidity.
What it costs in Austin
Radiant barrier with ventilation correction for a typical Austin home ranges $2,500-$5,000 including additional intake and exhaust venting.
How we do it
We calculate net free vent area, install balanced soffit and ridge ventilation, then apply radiant barrier with maintained air gaps so heat exits rather than circulating.
What Radiant Barrier Installation Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Attic radiant barrier (foil) | $1,500 - $3,500 |
| Spray-applied radiant coating | $2,000 - $4,500 |
| Radiant barrier with ventilation | $2,500 - $5,000 |
Does radiant barrier work with spray foam?
Not in the same space. Spray foam on the roof deck creates a conditioned attic, eliminating the need for radiant barrier there; we choose one strategy or the other based on your ductwork location and budget.
How much can radiant barrier lower my bill?
Austin homeowners with unsealed attics and ductwork in the attic typically see 10-20% cooling load reduction after proper radiant barrier and air sealing, verified by before-and-after blower-door tests.
Insulation Removal & Replacement in Austin
Austin’s ECAD audit reports flag settled or contaminated insulation as a standard deficiency, and we’ve removed original blown-in fiberglass from Allandale and Crestview homes that had compressed to R-8 or less over sixty years. The rapid East Austin flip cycle means thousands of cosmetically renovated homes still carry untouched, decades-old attic insulation beneath fresh finishes - insulation that fails ECAD and becomes a negotiating point in the option period.
We don’t add new material over old. Removal is the first step of any replacement job, and we document the condition we find with photos you receive before new insulation goes in.
Attic Insulation Removal
Signs you need it
Your insulation is compressed below the joist tops, has dark staining from air leakage, or was installed before 1990 and never assessed.
What it costs in Austin
Attic insulation removal for a typical Austin home runs $1,000-$2,500 depending on square footage, access difficulty, and whether the material is bagged or vacuum-extracted.
How we do it
We set up negative air containment, remove material with commercial vacuum equipment or by bagging, dispose per local code, and inspect the deck before any new work begins.
Contaminated Insulation Removal
Signs you need it
You’ve had roof leaks, rodent activity, or visible mold in the attic, or the insulation smells musty when the HVAC runs.
What it costs in Austin
Contaminated insulation removal with sanitizing for a typical Austin attic ranges $2,000-$4,500 depending on contamination extent and whether decking needs replacement.
How we do it
We suit for biohazard containment, remove contaminated material, apply EPA-registered sanitizer to exposed surfaces, and provide photo documentation before replacement begins.
What Insulation Removal & Replacement Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Standard attic removal | $1,000 - $2,500 |
| Contaminated removal + sanitize | $2,000 - $4,500 |
| Removal + replacement (full) | $3,500 - $8,000 |
Do I have to leave during insulation removal?
No. We set up containment and negative air machines that keep the work isolated to the attic. Most Austin homeowners stay in the house during removal.
How do I know if my old insulation is hazardous?
Vermiculite installed before 1990 may contain asbestos; we test before disturbing it. Other materials we assess visually and by odor - call (737) 259-8352 for an inspection and written scope.
Attic Air Sealing in Austin
Austin’s 140°F attic temperatures mean every cubic foot of conditioned air that leaks into the attic is air your HVAC already paid to cool, and the 1980s-2000s tract homes that dominate the market were built with minimal attention to top plate gaps, can light penetrations, or duct boot sealing. Attic air sealing is the single highest-ROI envelope upgrade in this climate, which is why we complete it before adding any insulation - never after, never as an optional add-on.
We publish before-and-after blower-door numbers on every job so you can verify the actual air-leakage reduction, not just take our word for it.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at interior wall tops, see dusty streaks around ceiling fixtures, or your blower-door test shows excessive leakage at the attic floor.
What it costs in Austin
Top plate and penetration sealing for a typical Austin home runs $800-$2,000 depending on wall count and accessibility.
How we do it
We access the attic perimeter, seal all top plate gaps with fire-rated caulk or foam, and treat every wire, pipe, and chimney penetration with appropriate gasket or sealant.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in wind, you feel conditioned air at ceiling registers when the system is off, or your ducts are routed through an unconditioned attic.
What it costs in Austin
Can light and duct boot sealing for a typical Austin home ranges $600-$1,800 depending on fixture count and whether boots need reconstruction.
How we do it
We install fire-rated covers over can lights, seal duct boots with mastic and mechanical fasteners, and pressure-test the system before closing.
What Attic Air Sealing Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Top plate & penetration sealing | $800 - $2,000 |
| Can light & duct boot sealing | $600 - $1,800 |
| Full attic air sealing | $1,500 - $3,500 |
Can air sealing alone lower my bill?
Yes. Austin homeowners typically see 15-25% HVAC load reduction from comprehensive attic air sealing before any insulation is added, verified by blower-door test.
Do you seal around recessed lights?
We install fire-rated airtight covers, never spray foam directly against fixtures, and document each with photos in your record.
Wall Insulation in Austin
Austin’s 1940s-60s bungalows and ranch homes in Allandale, Crestview, and Hyde Park were built with empty stud cavities or minimal rock wool, while the 1980s-2000s tract construction used R-11 or R-13 in walls at a time when the energy code was permissive. Wall insulation in Austin addresses a different problem than attic work: conductive heat gain through west- and south-facing walls that makes rooms uninhabitable in afternoon sun, and the complete absence of thermal buffer in older homes that were never designed for the cooling loads they now carry.
We insulate walls from the interior or exterior depending on siding type, finish condition, and whether the home is in an active ECAD transaction where interior disruption must be minimized.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, rooms on the west side stay 10°F warmer, or you can hear outdoor conversation through the wall.
What it costs in Austin
Drill-and-fill cellulose or fiberglass for a typical Austin home runs $2,000-$5,000 depending on wall area, cavity condition, and exterior finish type.
How we do it
We drill 2-inch holes at stud bay spacing, blow in dense-packed cellulose or fiberglass with controlled fill density, plug with matching material, and texture to blend.
Injection Foam Wall Insulation
Signs you need it
Your walls have irregular cavities, obstructions that prevent dense-pack, or you need air sealing and insulation in one step without removing drywall.
What it costs in Austin
Injection foam wall insulation for a typical Austin home ranges $3,000-$7,000 depending on foam type, wall area, and whether we access from interior or exterior.
How we do it
We inject slow-rise foam through sequentially drilled ports, monitor fill with thermal imaging, and verify complete cavity fill before sealing access points.
What Wall Insulation Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Drill & fill (cellulose/fiberglass) | $2,000 - $5,000 |
| Injection foam | $3,000 - $7,000 |
| Exterior wall with siding removal | $4,500 - $9,000 |
Will drill-and-fill damage my walls?
We match texture and paint after plugging; in Austin’s active ECAD market, we’ve refined the repair process so most homeowners can’t locate the access points afterward.
Can you insulate walls without removing drywall?
Yes. Drill-and-fill and injection foam both access cavities through small exterior or interior penetrations; we choose the approach based on your siding type and finish condition.
Attic Cleaning & Rodent Proofing in Austin
Austin’s mature tree canopy in neighborhoods like Allandale and Crestview, combined with rooflines that often have fascia gaps from decades of settlement, creates entry highways for roof rats and squirrels into attics that are already hospitable from settled, compressed insulation. The 140°F summer temperatures don’t deter rodents; they nest in the cooler perimeter near soffits and gable vents, contaminating insulation with urine and feces that becomes an airborne concern when HVAC systems draw from attic return pathways.
We clean and sanitize before we proof, because sealing entry points over a contaminated attic traps the problem inside.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia in the attic or through ceiling fixtures, see rodent droppings, or have had confirmed rodent activity in the past 12 months.
What it costs in Austin
Attic sanitizing and decontamination for a typical Austin home runs $1,500-$3,500 depending on contamination extent and whether insulation removal is required first.
How we do it
We remove contaminated material, apply EPA-registered disinfectant with commercial fogging equipment, HEPA-vacuum all surfaces, and provide photo documentation before any new work.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, see chew marks at soffit corners, or have had repeated rodent returns after trapping efforts.
What it costs in Austin
Rodent proofing and exclusion for a typical Austin home ranges $800-$2,500 depending on entry point count, roof complexity, and whether we install ridge guard or gable vent screening.
How we do it
We inspect with photo documentation, seal all entry points 1/4-inch and larger with rodent-proof materials, install hardware cloth over vents, and provide a written warranty on exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Attic sanitizing & decontamination | $1,500 - $3,500 |
| Rodent proofing & exclusion | $800 - $2,500 |
| Full attic restoration (clean + proof + insulate) | $3,500 - $8,500 |
Will rodents return after you seal the attic?
Our exclusion work carries a written warranty; we warranty the seal, not the biology, because new entry points can develop from storm damage or neighbor construction.
Do I need to remove insulation if rodents were in the attic?
Yes. Rodent urine and feces in insulation become airborne particulates; we sanitize and remove contaminated material before any new insulation goes in, per EPA guidance.
Home Energy Audit in Austin
Austin’s ECAD ordinance makes the home energy audit a transaction requirement, not an optional upgrade, and the report Austin Energy requires becomes a negotiating document in real estate deals - buyers routinely use flagged attic R-values or absent air sealing as price concession levers. We perform audits that meet ECAD compliance and go deeper, with blower-door testing and thermal imaging that shows exactly where the envelope is failing, not just whether it passes the ordinance threshold.
Our audits include a written scope and prioritized recommendations with prices, so you leave knowing what each fix costs, not just that fixes are needed.
Blower Door Test
Signs you need it
You’re selling or buying a home over 10 years old in Austin, your ECAD audit flagged air leakage, or you want a single number that quantifies your home’s envelope performance.
What it costs in Austin
A standalone blower-door test for a typical Austin home runs $300-$600; as part of a full energy audit, it’s included in the package price.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure - to pinpoint leakage magnitude and location.
Thermal Imaging Inspection
Signs you need it
You have rooms that won’t hold temperature, suspect missing insulation in walls, or want visual proof of air leakage for an ECAD negotiation.
What it costs in Austin
Thermal imaging inspection for a typical Austin home ranges $200-$500 as a standalone service, or included with a full audit.
How we do it
We scan the envelope with a FLIR camera during blower-door depressurization to make air leaks visible as temperature differentials, then mark each finding on a floor plan you receive.
What Home Energy Audit Costs in Austin
| Item | Typical range in Austin |
|---|---|
| Blower-door test (standalone) | $300 - $600 |
| Thermal imaging inspection | $200 - $500 |
| Full home energy audit (ECAD-compliant) | $400 - $800 |
Does your audit satisfy Austin ECAD requirements?
Yes. Our audits meet Austin Energy’s ECAD compliance standards and include the required documentation for real estate transactions.
How soon do I get the audit report?
We deliver a written report with blower-door numbers, thermal images, and prioritized recommendations within 24 hours; call (737) 259-8352 to schedule.
