Insulation in Brushy Creek, TX
Crawl space encapsulation and vapor barrier installation in Brushy Creek typically runs $3,500-$7,500 for most homes, with full encapsulations on larger crawl spaces reaching toward the upper end. We’re Envelope Insulation Co., and we’ve sealed and insulated more than 9,000 homes since 2016 under The Haven Standard - every job starting with a written price and ending with a documented photo record. In Brushy Creek, our crews find the same pattern repeating: 1990s-2000s tract homes with vented crawl spaces that were never properly sealed against the Blackland Prairie humidity or the occasional hard freeze.

Why Brushy Creek Homes Are Different
Brushy Creek’s housing stock is overwhelmingly concentrated in a tight 1990s-2000s construction window driven by the Central Texas tech boom. That means the vast majority of homes have builder-grade fiberglass batts installed to the minimum code of that era - typically R-19 to R-30 in attics - that are now 20-30 years old, compressing and settling. These homes sit just north of Austin in one of Texas’s most brutal cooling-load zones, where attic temperatures regularly exceed 140°F in July and August.
The February 2021 Winter Storm Uri exposed how the same under-insulated attics and interior wall cavities that bleed heat in summer allowed pipes to freeze in a community that assumed it would never need serious thermal protection against cold. The terrain doesn’t help: Brushy Creek sits in the transition zone between the Blackland Prairie and the Balcones Escarpment, where the limestone substrate and seasonal clay expansion stress foundation seals and create pathways for ground moisture into crawl spaces. A technician working Brushy Creek’s subdivisions will find that the same floor plan - the same builder, the same vintage, the same R-25 blown fiberglass - repeats street after street, so a single neighborhood audit often reveals the same thermal bridging at the knee-wall junctions of those ubiquitous two-story bonus rooms.
Our Main Brushy Creek Services
Brushy Creek homeowners call us most often for attic work and spray foam - here is what each job involves locally.
Attic Insulation in Brushy Creek
Most Brushy Creek attics we enter still hold the original blown fiberglass from the build year, settled to R-19 or below and often disturbed by decades of HVAC service traffic. We remove or augment as needed, air seal the floor first, then install to current IECC standards for our climate zone. Every attic job gets a written price before work starts and a documented photo record when we leave. Attic Insulation in Brushy Creek details our full process and blower-door verification.

Spray Foam Insulation in Brushy Creek
Spray foam makes particular sense in Brushy Creek’s older two-story homes with bonus rooms and kneewalls, where conventional batts leave persistent hot spots. We specify open-cell for attic floors and closed-cell for rim joists and crawl spaces, sourced from Owens Corning and Demilec. Every foam job includes before-and-after blower-door numbers so you can verify the air-sealing result. Spray Foam Insulation in Brushy Creek covers applications and pricing.

Blown-In Insulation in Brushy Creek
Blown-in cellulose and fiberglass remain the most cost-effective retrofits for Brushy Creek’s standard vented attics, especially when topping off existing material that is still clean and reasonably placed. We use GreenFiber cellulose and Owens Corning fiberglass, never blowing new material over an unsealed attic floor. The Haven Standard requires air sealing of top plates, can lights, and penetrations first. Blown-In Insulation in Brushy Creek explains our prep and installation sequence.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Brushy Creek

Brushy Creek’s 1990s-2000s slab and pier homes were built with vented crawl spaces that assumed Central Texas ground moisture would simply dissipate - it doesn’t. The Blackland Prairie clay holds water through spring and fall, and the limestone substrate channels it toward foundation gaps. In February 2021, homes with encapsulated crawl spaces maintained pipe temperatures 15-20 degrees higher than vented ones. Crawl Space Encapsulation & Vapor Barrier is our primary service in Brushy Creek because the housing stock and soil conditions make it unavoidable.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or floor joists that feel damp to the touch.
What it costs in Brushy Creek
A 6-mil to 20-mil vapor barrier installation for a standard Brushy Creek crawl space runs $1,500-$3,500 depending on mil thickness, seam sealing, and whether piers need wrapping.
How we do it
We clear debris, grade the soil toward a central low point or sump location, lay overlapping polyethylene sheeting with sealed seams, and fasten to walls and piers so the barrier stays intact during future HVAC or plumbing service.
Crawl Space Encapsulation
Signs you need it
You smell mustiness in first-floor rooms, your hardwood floors cup seasonally, or your HVAC ducts in the crawl space sweat condensation in summer.
What it costs in Brushy Creek
Full encapsulation with closed-cell foam on walls, sealed vapor barrier on floor, and mechanical dehumidification typically ranges $5,000-$12,000 for Brushy Creek homes.
How we do it
We seal all vents, apply closed-cell spray foam to foundation walls, install the vapor barrier floor system, add a commercial dehumidifier with condensate pump, and verify with humidity logging for 30 days post-installation.
What Crawl Space Encapsulation & Vapor Barrier Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Vapor barrier (6-20 mil, floor only) | $1,500 - $3,500 |
| Partial encapsulation (walls + floor, no dehumidifier) | $3,500 - $7,500 |
| Full encapsulation with dehumidification | $5,000 - $12,000 |
How long does crawl space encapsulation take in Brushy Creek?
Most Brushy Creek encapsulations finish in 2-4 days depending on crawl space accessibility and whether we need to address active moisture sources first. We deliver a written schedule with your written price before anyone starts.
Will encapsulation help with winter pipe protection?
Yes - a sealed, insulated crawl space maintains temperatures 15-20°F warmer than a vented one, which is the difference between frozen and intact pipes during events like Uri. Call (737) 252-7159 to discuss your specific foundation type.
Radiant Barrier Installation in Brushy Creek

Brushy Creek’s 1990s-2000s homes were roofed with dark asphalt shingles over vented attics, a combination that pushes attic temperatures past 140°F on July afternoons and forces air conditioners to cycle almost continuously. A radiant barrier - a reflective foil or paint-on coating that blocks radiant heat transfer from roof deck to attic floor - can reduce attic heat gain by 20-35% in our climate zone. Radiant Barrier Installation pairs especially well with air sealing and additional insulation in Brushy Creek’s standard tract homes.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 p.m., your AC runs 14+ hours daily in summer, or your ductwork in the attic feels hot to the touch.
What it costs in Brushy Creek
Foil radiant barrier installed on attic rafters or truss chords in a standard Brushy Creek home runs $1,200-$2,800 depending on attic complexity and whether we combine it with air sealing.
How we do it
We staple perforated aluminum foil across rafter bays with proper drape for ventilation channels, seal all penetrations first, and verify with a blower-door test if air sealing is included.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing soon and want the most effective radiant barrier application, or your current roof deck is accessible from inside the attic for spray application.
What it costs in Brushy Creek
Spray-applied radiant barrier coating on the roof deck during a re-roof or retrofit costs $1,500-$3,500 for most Brushy Creek homes.
How we do it
We clean the roof deck, apply a low-emissivity coating to the underside of the sheathing, and ensure soffit-to-ridge ventilation remains unobstructed so moisture can still escape.
What Radiant Barrier Installation Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Foil radiant barrier (rafter installation) | $1,200 - $2,800 |
| Spray-applied roof deck coating | $1,500 - $3,500 |
| Radiant barrier with attic air sealing package | $2,500 - $4,500 |
Does radiant barrier work with existing insulation?
Yes - it works best when paired with adequate attic insulation, not as a replacement; the barrier blocks radiant heat, while insulation slows conductive heat flow through the attic floor. Call (737) 252-7159 for a free assessment of your current R-value.
How much can radiant barrier lower my cooling bill?
Most Brushy Creek homeowners see 5-15% summer cooling reduction, with the greatest impact on homes with ductwork in the attic; we document pre- and post-installation attic temperatures so you can verify the change.
Insulation Removal & Replacement in Brushy Creek

Brushy Creek’s 20-30-year-old fiberglass batts and blown-in have compressed, settled, and often been compromised by roof leaks, rodent activity, or decades of HVAC maintenance traffic. The original R-19 to R-30 installed to 1990s code now performs at a fraction of its labeled value. Insulation Removal & Replacement is frequently the first step before air sealing and proper re-insulation in Brushy Creek homes.
Attic Insulation Removal
Signs you need it
Your attic insulation is flat and compacted, has dark streaks from air leakage, or you’ve had a roof leak that soaked the material.
What it costs in Brushy Creek
Removal of existing blown or batt insulation from a standard Brushy Creek attic runs $1.00-$2.50 per square foot, typically $1,500-$3,500 total.
How we do it
We use commercial vacuums with HEPA filtration, bag the material on site, and inspect the deck for mold, rot, or gaps before any new insulation goes in.
Contaminated Insulation Removal
Signs you need it
You’ve found rodent droppings, nesting material, or urine staining in the insulation, or you smell ammonia when the HVAC runs.
What it costs in Brushy Creek
Contaminated removal with sanitizing and deodorizing runs $2.50-$5.00 per square foot in Brushy Creek, or $3,500-$7,500 for a typical attic.
How we do it
We wear PPE, use negative air pressure containment, remove all contaminated material, apply enzymatic sanitizer to the deck, and provide photo documentation of the clean substrate before re-insulation.
What Insulation Removal & Replacement Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Standard attic insulation removal | $1,500 - $3,500 |
| Contaminated insulation removal + sanitizing | $3,500 - $7,500 |
| Removal + replacement with new insulation | $4,500 - $10,000 |
Can you remove insulation with asbestos or vermiculite?
We do not handle asbestos-containing materials; if your Brushy Creek home was built before 1980, we test first and refer to licensed abatement if needed, then resume work with a clean deck. Call (737) 252-7159 to schedule a preliminary inspection.
How long does removal and replacement take?
Most Brushy Creek attic removals finish in one day, with replacement starting the next; contaminated jobs may add a day for sanitizing and drying - your written schedule specifies the timeline before work begins.
Attic Air Sealing in Brushy Creek

Brushy Creek’s 1990s-2000s homes were built with the attic floor treated as an afterthought - top plates, wire penetrations, and can lights left open to the attic, creating a direct path for conditioned air to escape into 140°F attic space. The blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - typically reveals 3,500-5,500 CFM50 in these homes before sealing. Attic Air Sealing is the prerequisite step we never skip; under The Haven Standard, we seal first, then insulate, in that order.
Attic Floor Air Sealing
Signs you need it
You feel drafts from ceiling fixtures, your upstairs rooms are 8-12 degrees warmer than downstairs, or your energy bills spike in summer despite a new AC unit.
What it costs in Brushy Creek
Comprehensive attic floor air sealing for a standard Brushy Creek home runs $1,200-$2,800 depending on square footage and number of penetrations.
How we do it
We seal all top plate joints, electrical and plumbing penetrations, and duct boots with fire-rated caulk and foam, then verify with a blower-door test to document the CFM50 reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed can lights flicker in wind, you see dust streaks around ceiling grilles, or your HVAC ducts in the attic sweat condensation.
What it costs in Brushy Creek
Sealing can lights with proper covers and mastic-sealing duct boots runs $400-$1,200 in Brushy Creek homes with 8-20 fixtures.
How we do it
We install fire-rated airtight covers over non-IC can lights, seal duct boots to ceiling drywall with mastic, and pressure-test the duct system if leakage is suspected.
What Attic Air Sealing Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Attic floor air sealing (comprehensive) | $1,200 - $2,800 |
| Can light sealing (per fixture) | $50 - $150 |
| Attic air sealing + insulation upgrade package | $3,500 - $7,500 |
Will air sealing make my attic too hot?
No - sealing the attic floor keeps conditioned air in your living space, not in the attic; we maintain proper soffit and ridge ventilation so the attic still vents, just without stealing your cooled air. Call (737) 252-7159 for a free blower-door assessment.
How much does air sealing reduce my energy bills?
Most Brushy Creek homeowners see 10-20% heating and cooling reduction after comprehensive attic air sealing, with the exact figure documented in your before-and-after blower-door report.
Wall Insulation in Brushy Creek

Brushy Creek’s 1990s-2000s tract homes were built with 2×4 exterior walls and minimal cavity insulation - often R-11 fiberglass batts with gaps at electrical boxes and studs - that performs poorly against both summer heat and winter cold. The knee walls and bonus room walls of those ubiquitous two-story plans are particularly vulnerable, creating thermal bridges that show up as hot spots in summer and cold zones during events like Uri. Wall Insulation retrofit is one of the most impactful upgrades for Brushy Creek homes that have already had attic work done.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in afternoon sun, your rooms have uneven temperatures, or you’ve completed attic work and still have high bills.
What it costs in Brushy Creek
Injection foam for exterior walls in a standard Brushy Creek home runs $3.00-$6.00 per square foot of wall area, typically $4,500-$9,000 total.
How we do it
We drill 2-inch holes between studs at top and bottom, inject slow-rise foam that fills the cavity without bowing drywall, patch and texture-match the holes, and verify fill with thermal imaging.
Drill & Fill Wall Insulation
Signs you need it
You have empty wall cavities from original construction shortcuts, or you’re remodeling and have wall access to add insulation without injection methods.
What it costs in Brushy Creek
Drill-and-fill with dense-pack cellulose or fiberglass runs $2.00-$4.50 per square foot in Brushy Creek, or $3,000-$7,000 for a typical home.
How we do it
We remove small siding or interior drywall sections, blow cellulose or fiberglass to proper density, seal all access points, and replace siding or patch drywall to match existing finish.
What Wall Insulation Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Injection foam (exterior walls) | $4,500 - $9,000 |
| Drill-and-fill cellulose/fiberglass | $3,000 - $7,000 |
| Interior wall soundproofing (per room) | $1,500 - $3,500 |
Can you insulate walls without removing drywall?
Yes - injection foam and dense-pack cellulose both fill cavities through small drilled holes that we patch and texture-match, though homes with brick or stone veneer require different access strategies we assess during your free estimate. Call (737) 252-7159 to schedule.
Will wall insulation help with sound?
Dense-pack cellulose and certain foam applications reduce exterior noise and between-room sound transmission significantly; we specify the product and density based on your priority - thermal, acoustic, or both.
Attic Cleaning & Rodent Proofing in Brushy Creek

Brushy Creek’s mature oak canopy and established neighborhoods create ideal rodent habitat, and 1990s-2000s homes have decades of roof penetrations, soffit gaps, and vent screens that squirrels and rats exploit to nest in attics. The documented photo record we provide on every visit often reveals chewed wires, compressed insulation with urine staining, and entry points that homeowners never access to see. Attic Cleaning & Rodent Proofing restores the space and prevents return - critical before any new insulation goes in.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at night, find droppings in the attic, or smell musty ammonia when the HVAC runs.
What it costs in Brushy Creek
Attic cleanout with removal of contaminated insulation, debris, and sanitizing runs $2,000-$4,500 for a standard Brushy Creek attic.
How we do it
We remove all contaminated material, HEPA-vacuum the deck, apply enzymatic sanitizer and deodorizer, and provide photo documentation of the clean substrate before any restoration work.
Rodent Proofing & Exclusion
Signs you need it
You’ve had recurring rodent issues despite trapping, or you can see daylight through soffit gaps, roof jack gaps, or vent screens with holes.
What it costs in Brushy Creek
Comprehensive rodent exclusion with hardware cloth, metal flashing, and sealant for a standard Brushy Creek home runs $1,500-$3,500.
How we do it
We inspect every roof penetration, soffit joint, and vent, install gnaw-proof materials, seal with polyurethane and metal where appropriate, and guarantee the work for one year with documented entry-point photos.
What Attic Cleaning & Rodent Proofing Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Attic cleanout + sanitizing | $2,000 - $4,500 |
| Rodent proofing & exclusion | $1,500 - $3,500 |
| Full restoration (cleanout + proofing + re-insulation) | $5,000 - $12,000 |
How do I know if rodents are in my attic?
Listen for scratching or running sounds at dawn and dusk, inspect insulation for compressed trails or droppings, and check soffits and roof vents for chewed or displaced screens - we document all evidence during our free inspection. Call (737) 252-7159 to schedule.
Will rodent proofing keep all pests out?
Our exclusion targets rodents specifically; we seal to 1/4-inch tolerance for mice and 1/2-inch for rats, but ongoing maintenance of seals and vegetation clearance is the homeowner’s responsibility for long-term protection.
Home Energy Audit in Brushy Creek

A home energy audit in Brushy Creek identifies the specific thermal and air-leakage failures that are endemic to this area’s 1990s-2000s housing stock - the same builder, the same vintage, the same failure modes repeating street after street. The blower-door test, thermal imaging, and duct-blaster results give you a prioritized scope with actual numbers, not guesses. Home Energy Audit is where every significant Brushy Creek retrofit should start, and where we document the baseline that later work will be measured against.
Blower Door Test
Signs you need it
Your energy bills are 30-50% higher than neighbors with similar homes, you feel drafts you can’t locate, or you’re planning major insulation work and want a baseline.
What it costs in Brushy Creek
A standalone blower-door test with written report runs $300-$600 in Brushy Creek; it’s credited toward any work we perform within 90 days.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 leakage, and use smoke pencils and thermal imaging to locate the dominant leak paths while the house is under test.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach set temperature, suspect missing wall insulation, or want to verify the quality of previous insulation work.
What it costs in Brushy Creek
Thermal imaging as part of a full audit runs $200-$400; standalone imaging inspection is $250-$500 depending on home size and number of images documented.
How we do it
We scan every exterior wall, ceiling, and foundation junction with a calibrated infrared camera during heating or cooling season when temperature differentials are strongest, and annotate images with R-value estimates and recommended actions.
What Home Energy Audit Costs in Brushy Creek
| Item | Typical range in Brushy Creek |
|---|---|
| Blower-door test with written report | $300 - $600 |
| Full home energy audit (blower door + thermal + duct test) | $500 - $900 |
| Thermal imaging inspection (standalone) | $250 - $500 |
How long does a home energy audit take?
Most Brushy Creek audits take 3-4 hours including setup, testing, and a walkthrough of preliminary findings; your written report with prioritized recommendations and photo documentation arrives within 48 hours. Call (737) 252-7159 to book.
Will an audit tell me exactly what to fix first?
Yes - your report ranks improvements by cost-effectiveness and comfort impact, with estimated savings for each measure, so you can phase work according to budget rather than guessing.
