Austin’s housing stock presents a split problem: central neighborhoods like Hyde Park and Bouldin Creek still rest on original pier-and-beam foundations with open crawl spaces that breathe summer humidity and winter cold directly into floor systems, while the 1990s-2000s production belt across North Austin and South Austin hides another issue - vented attics with settled fiberglass and ductwork baking in 150°F heat. We treat the full envelope, sealed first, then insulated, with blower-door numbers published on every applicable job.

Why Austin Homes Are Different

Austin sits in IECC Climate Zone 2, where attic temperatures routinely hit 140-155°F and the city logs more than 90 days above 90°F annually. That heat load dominates every insulation decision, but February 2021’s Winter Storm Uri changed the conversation permanently. Homes built almost entirely around cooling-season heat rejection couldn’t retain warmth during a multi-day hard freeze, and we’ve seen a sustained surge in full-envelope upgrades ever since - customers who once only cared about summer electric bills now ask about winter performance too.

The housing split matters for scope. Pre-1960s bungalows in Travis Heights and Clarksville have uninsulated floor decks and open crawl spaces that need encapsulation before any upper-floor work makes sense. The production-home ring across Pflugerville, Cedar Park, and South Austin corridors typically has R-19 to R-30 blown fiberglass that has settled or been trampled by HVAC crews, with flexible ductwork running through unconditioned attic space that acts like a solar collector. Austin Energy’s rebate program adds a paperwork layer competitors often miss: insulation projects within city limits must meet specific R-value thresholds and air-sealing benchmarks verified by a certified rater. We pair every scope with blower-door documentation so homeowners capture those rebates without chasing signatures later.

Our Main Austin Services

These are the three services Austin homeowners call about most often. Each has its own dedicated Austin page with deeper pricing and neighborhood-specific notes.

Attic Insulation in Austin

Attic insulation in Austin means dealing with vented attics that function as unconditioned ovens six months a year. We start with air sealing of top plates, can lights, and penetrations - blower-door verified - before adding any new material. Most production homes in the North Austin and Pflugerville corridors were built to R-30 that has settled to R-22 or below. Attic Insulation in Austin covers full scope, pricing, and Austin Energy rebate pairing.

Spray Foam Insulation in Austin

Spray foam in Austin has shifted since Uri. Roof-deck encapsulation - converting a vented attic to a conditioned assembly - now accounts for a growing share of our Austin work, especially in older homes with HVAC equipment and ductwork in the attic. We use open-cell and closed-cell products from Icynene and Demilec, selected by application, never pushed by brand incentive. Spray Foam Insulation in Austin breaks out cost by assembly type and code path.

Blown-In Insulation in Austin

Blown-in fiberglass and cellulose remain the most cost-effective way to restore settled attic insulation in Austin’s production-home belt. We blow only after air sealing is complete and documented - never over an unsealed attic floor, per our hard prerequisite. GreenFiber cellulose and Owens Corning fiberglass are both stocked locally for next-day starts. Blown-In Insulation in Austin lists current per-square-foot pricing and density requirements.

Crawl Space Encapsulation & Vapor Barrier in Austin

Crawl space encapsulation in Austin solves a problem specific to the city’s central neighborhoods: pre-1960s pier-and-beam bungalows in Hyde Park, Travis Heights, and Bouldin Creek were built with open crawl spaces that exchange air freely with soil moisture and seasonal temperature swings. Summer humidity rises through floor decking and meets cooled interior surfaces, creating condensation cycles that rot joists and grow mold. Crawl Space Encapsulation & Vapor Barrier covers our full methodology, but the Austin-specific scope starts with soil moisture control and ends with a conditioned, sealed crawl space that reads like interior space on a blower-door test.

Crawl Space Vapor Barrier

Signs you need it

Your floors feel cold in winter despite the heater running, or you notice musty odors rising from closets and baseboard gaps in older central Austin homes.

What it costs in Austin

A 6-mil to 20-mil vapor barrier installed across bare soil in a typical central Austin crawl space runs $3,500 to $5,500 depending on access clearance and pier count.

How we do it

We clear debris, grade the soil for drainage, seam-seal the barrier to foundation walls and piers, and deliver a Documented Photo Record showing full coverage before any insulation work begins.

Crawl Space Encapsulation

Signs you need it

You’re seeing sagging insulation between joists, visible mold on floor decking, or pest activity concentrated in the crawl space during Austin’s spring and fall shoulder seasons.

What it costs in Austin

Full encapsulation with sealed vapor barrier, rigid foam wall insulation, and mechanical dehumidification for a standard central Austin crawl space ranges from $6,500 to $8,500.

How we do it

We install the vapor barrier, seal vents and penetrations, apply rigid foam to foundation walls, add a dedicated dehumidifier with condensate pump, and verify the assembly with before-and-after blower-door readings.

What Crawl Space Encapsulation & Vapor Barrier Costs in Austin

Does crawl space encapsulation help with summer humidity in Austin?

Yes. Sealing the crawl space and adding mechanical dehumidification drops relative humidity below 60% year-round, stopping the condensation cycle that damages floor systems during Austin’s humid shoulder seasons. Call (737) 337-8049 for a written price and free second opinion on any competing quote.

Can you encapsulate a crawl space with low clearance?

We regularly work in central Austin crawl spaces with 18 to 24 inches of clearance; access constraints affect labor hours and are noted in the written scope before work starts. Call (737) 337-8049 to schedule access evaluation.

Radiant Barrier Installation in Austin

Radiant barrier installation in Austin addresses the dominant cooling-season load: attic temperatures exceeding 140°F push heat through conventional insulation by radiation, not just conduction. In the production-home belt across North Austin, Pflugerville, and South Austin corridors, we’ve measured roof deck surface temperatures above 170°F in July, with radiant heat transfer accounting for a significant share of the cooling burden that HVAC systems struggle against. Radiant Barrier Installation details our full product line, but Austin jobs typically pair radiant barrier with ventilation correction and air sealing for measured performance change.

Attic Radiant Barrier

Signs you need it

Your upstairs rooms run 8 to 12 degrees warmer than downstairs, or your AC cycles continuously after 2 p.m. despite correct refrigerant charge and duct sizing.

What it costs in Austin

Attic radiant barrier installation for a typical 2,000-square-foot Austin home runs $1,800 to $3,200 depending on roof pitch, existing insulation depth, and whether we access via attic or roof-deck path.

How we do it

We install perforated radiant barrier foil across rafter bottoms or truss chords, maintaining ventilation channels, and pair the work with top-plate air sealing verified by blower-door test.

Radiant Barrier Roof Deck

Signs you need it

You’re planning a roof replacement or have exposed decking during repairs, and you want to stop radiant heat at the source rather than filtering it through attic insulation.

What it costs in Austin

Radiant barrier applied directly to roof deck during construction or re-roofing in Austin ranges from $2,500 to $4,500 for the radiant component alone, before insulation upgrade.

How we do it

We apply radiant barrier sheathing or foil directly to the deck, integrate with drip edge and ventilation details, and document the assembly with photos and written scope under Haven Standard Clause 1.

What Radiant Barrier Installation Costs in Austin

Does radiant barrier work with spray foam in Austin?

Radiant barrier and spray foam serve different heat-transfer modes; we typically specify one or the other based on whether the attic remains vented or is converted to conditioned space. Call (737) 337-8049 and we’ll walk through the physics for your specific roof assembly.

How much does radiant barrier lower attic temperature in Austin?

Properly installed radiant barrier can reduce attic surface temperatures by 20 to 35 degrees during peak summer conditions, though the measured savings show up in reduced cooling runtime, not thermostat setpoint change. Call (737) 337-8049 for a written price and blower-door baseline.

Insulation Removal & Replacement in Austin

Insulation removal and replacement in Austin is often triggered by contamination, not age - rodent activity in attics, water damage from roof leaks or HVAC condensate, or fire restoration work leaves fiberglass and cellulose unusable. In the 1990s-2000s production belt, we’ve also found vermiculite insulation in homes built before 1990 that requires abatement-protocol removal, and trampled, HVAC-compacted fiberglass that no longer meets its labeled R-value. Insulation Removal & Replacement covers our full containment and disposal process, but Austin jobs add the complication of summer heat: we schedule removals early and use negative-air containment to protect living space.

Contaminated Insulation Removal

Signs you need it

You’ve found rodent droppings, nesting material, or urine staining in attic insulation, or you smell musty or ammonia odors that intensify when HVAC runs.

What it costs in Austin

Contaminated insulation removal with HEPA containment, bagging, and disposal for a typical Austin attic runs $2,500 to $4,500 before replacement insulation.

How we do it

We establish negative-air containment, remove contaminated material in sealed bags, HEPA-vacuum all surfaces, apply antimicrobial treatment where indicated, and deliver a Documented Photo Record of clean decking before any new insulation goes in.

Vermiculite & Old Insulation Removal

Signs you need it

Your attic contains gray-brown granular material that resembles small pebbles, or you’re in a pre-1990 Austin home with unknown insulation history and need verification before disturbance.

What it costs in Austin

Vermiculite removal following EPA abatement protocols in Austin ranges from $4,500 to $8,500 depending on volume, accessibility, and lab-confirmed asbestos content.

How we do it

We sample and lab-test before disturbance, then execute full abatement protocol with licensed waste disposal, air clearance testing, and written documentation for real estate disclosure.

What Insulation Removal & Replacement Costs in Austin

Can you remove insulation in summer in Austin?

Yes, we work year-round using early-morning scheduling and portable cooling for crew safety; negative-air containment protects your living space regardless of season. Call (737) 337-8049 to schedule around your availability and our heat-safety protocols.

Do I need to leave during insulation removal?

For standard fiberglass or cellulose removal, no; for vermiculite abatement, we establish sealed containment and recommend occupancy elsewhere during active removal, with air clearance testing before re-entry. Call (737) 337-8049 and we’ll specify the protocol for your material type.

Attic Air Sealing in Austin

Attic air sealing in Austin is the single most cost-effective envelope upgrade for homes with HVAC ductwork in vented attics, which describes most of the production housing stock in North Austin, Pflugerville, and South Austin. We regularly measure 4,000 to 6,000 CFM50 on pre-2000 homes before sealing, with conditioned air leaking directly into 150°F attic space - air you’ve already paid to cool. Attic Air Sealing details our full penetration map, but Austin jobs focus heavily on top plates, can lights, and duct boots because those are the dominant leakage paths in the local housing stock.

Top Plate & Penetration Sealing

Signs you need it

Your blower-door test shows high leakage at the attic floor plane, or you feel drafts at outlets and switch plates on exterior walls during Austin’s winter cold fronts.

What it costs in Austin

Top plate and penetration sealing for a typical 2,000-square-foot Austin home runs $1,800 to $3,200, with blower-door verification included.

How we do it

We access top plates at eaves and interior partitions, seal with foam and gasket materials appropriate to gap size, and verify with blower-door test-out showing CFM50 reduction.

Can Light & Duct Boot Sealing

Signs you need it

You have recessed can lights in ceilings below attic space, or your HVAC supply registers show dust staining around edges indicating attic pressure differentials.

What it costs in Austin

Can light sealing with rated enclosures and duct boot sealing with mastic and mechanical fasteners in Austin ranges from $1,200 to $2,800 depending on fixture count and duct configuration.

How we do it

We install fire-rated enclosures over non-IC cans, seal all duct boots with mastic and draw bands, and pressure-test the duct system where accessible.

What Attic Air Sealing Costs in Austin

Does attic air sealing qualify for Austin Energy rebates?

Yes, Austin Energy’s rebate program requires verified air-sealing performance measured by blower-door test, which we provide as standard documentation on every applicable job. Call (737) 337-8049 and we’ll pair your scope with the rebate paperwork.

Can air sealing alone reduce my electric bill in Austin?

Yes, we’ve measured 15 to 25 percent cooling load reduction from air sealing alone in leaky Austin attics, though we typically recommend sealing before insulating to avoid burying leaks under new material. Call (737) 337-8049 for a written scope and blower-door baseline.

Wall Insulation in Austin

Wall insulation in Austin addresses a gap in the production-home belt: 1990s-2000s homes across North Austin, Pflugerville, and Cedar Park were built with 2×4 walls and minimal cavity insulation, or in some cases empty cavities where insulation settled or was never fully installed. The cooling-dominated climate meant builders prioritized attic performance over wall R-value, but Austin’s temperature swings and post-Uri heating concerns have made wall insulation a growing retrofit. Wall Insulation covers our full injection and drill-and-fill methods, but Austin jobs must navigate stucco and hardcoat exterior finishes common in the area.

Injection Foam Wall Insulation

Signs you need it

Your walls feel warm to the touch in summer, or you have rooms with western exposure that never reach setpoint despite correct attic insulation and duct sizing.

What it costs in Austin

Injection foam wall insulation for a typical 2,000-square-foot Austin home with accessible cavities runs $4,500 to $7,500 depending on wall area and exterior finish type.

How we do it

We drill access holes at stud bay intervals, inject slow-rise foam to fill cavities without bowing drywall, patch and match texture, and provide a Documented Photo Record of fill completeness via thermal imaging.

Drill & Fill Wall Insulation

Signs you need it

Your home has empty or poorly filled wall cavities discovered during renovation, or blower-door testing shows significant leakage at the wall plane despite sealed attic and floor.

What it costs in Austin

Drill-and-fill with dense-pack cellulose or fiberglass for a typical Austin home ranges from $3,500 to $6,000, with exterior patching included for wood or fiber-cement siding.

How we do it

We remove siding or drill through exterior sheathing, dense-pack cavities to specified density, seal penetrations, and replace or patch finish materials to match existing.

What Wall Insulation Costs in Austin

Can you insulate walls without removing drywall in Austin?

Yes, injection foam and dense-pack cellulose both fill existing cavities through small exterior or interior access points, with patching that matches most Austin finishes. Call (737) 337-8049 for a written price based on your wall construction and finish type.

Does wall insulation help with sound in Austin?

Dense-pack cellulose and certain foam products reduce airborne sound transmission by 5 to 10 STC points, which matters on Austin’s busier corridors like Lamar, Burnet, and South Congress. Call (737) 337-8049 and we’ll specify acoustic-rated products where traffic noise is the primary concern.

Attic Cleaning & Rodent Proofing in Austin

Attic cleaning and rodent proofing in Austin is a humid-climate specialty: our warm seasons extend rodent breeding cycles, and oak-dominated neighborhoods like Tarrytown, Bryker Woods, and Allandale provide continuous canopy access to rooflines. Once squirrels or roof rats access an Austin attic, they compress and contaminate insulation, creating a loop where reduced R-value drives longer HVAC runtime and higher energy bills. Attic Cleaning & Rodent Proofing covers our full exclusion methodology, but Austin jobs emphasize roof-line entry points because tree access is the dominant vector.

Rodent Proofing & Exclusion

Signs you need it

You hear scratching or running above ceiling planes at dawn or dusk, or you’ve found droppings, gnawed wiring, or nesting material in attic insulation.

What it costs in Austin

Rodent proofing and exclusion for a typical Austin home with accessible roofline runs $1,800 to $3,500, with one-year revisit guarantee.

How we do it

We map all entry points with photo documentation, seal with rodent-proof materials, install one-way exits where active infestation exists, and deliver a written exclusion report with photo record.

Attic Sanitizing & Decontamination

Signs you need it

Your attic insulation shows urine staining, you smell ammonia or musk odors that enter living space through recessed lights, or you’ve completed exclusion and need biological cleanup before replacement insulation.

What it costs in Austin

Attic sanitizing and decontamination with HEPA vacuuming, enzyme treatment, and antimicrobial application in Austin ranges from $2,200 to $4,000 depending on contamination extent and attic square footage.

How we do it

We remove contaminated insulation if present, HEPA-vacuum all surfaces, apply enzyme and antimicrobial treatments, and provide a Documented Photo Record of pre- and post-condition before any new materials are specified.

What Attic Cleaning & Rodent Proofing Costs in Austin

How do rodents get into Austin attics?

Tree branches within 6 feet of roofline, unscreened vents, and construction gaps at fascia-soffit junctions are the three dominant entry paths in Austin’s mature neighborhoods; we address all three in our exclusion scope. Call (737) 337-8049 for a written price and entry-point mapping.

Do you clean attics with active rodents present?

We complete exclusion first to stop new entry, then schedule cleaning and insulation replacement once one-way exits have cleared remaining animals; doing both simultaneously wastes money on re-contamination. Call (737) 337-8049 and we’ll sequence the work correctly.

Home Energy Audit in Austin

A home energy audit in Austin is most valuable when it precedes any insulation scope, not follows it - we use the audit to build a prioritized scope rather than validate work already sold. Austin Energy’s rebate program requires a certified rater and specific blower-door thresholds, so our audits are designed to produce documentation that feeds directly into rebate applications without duplicate testing. Home Energy Audit details our full diagnostic suite, but Austin audits emphasize attic duct leakage and wall cavity assessment because those are the dominant performance gaps in local housing stock.

Blower Door Test

Signs you need it

You’re considering insulation upgrades and need a baseline leakage number to prioritize air sealing against insulation, or you’re pursuing Austin Energy rebates that require certified blower-door documentation.

What it costs in Austin

A standalone blower-door test with written report and CFM50 documentation in Austin runs $350 to $550; when bundled with thermal imaging and duct testing, $650 to $950.

How we do it

We install a calibrated blower door in an exterior doorway, depressurize the house to -50 Pascals, measure CFM50 leakage, and identify dominant leakage paths with smoke pencil and thermal imaging.

Thermal Imaging Inspection

Signs you need it

You have rooms that never reach temperature, suspect missing wall insulation, or need to verify insulation continuity before specifying attic or wall scope.

What it costs in Austin

Thermal imaging inspection as part of a full energy audit in Austin ranges from $650 to $950 including blower-door test and written report with prioritized scope.

How we do it

We scan all building surfaces with calibrated infrared camera during controlled temperature differential, mark anomalies on photos, and correlate findings with blower-door data to distinguish air leakage from insulation gaps.

What Home Energy Audit Costs in Austin

Does a home energy audit qualify for Austin Energy rebates?

Austin Energy requires pre- and post-work blower-door tests by a certified rater for rebate eligibility; our audits include this documentation and we guide the rebate application. Call (737) 337-8049 to schedule an audit that feeds directly into your rebate path.

How long does a home energy audit take in Austin?

A full diagnostic audit including blower-door test, thermal imaging, and duct leakage testing takes 3 to 4 hours for a typical Austin home, with the written report and prioritized scope delivered within 48 hours. Call (737) 337-8049 to schedule and receive your written price before the auditor arrives.
