Insulation in Hornsby Bend, TX
Crawl space encapsulation and vapor barrier work in Hornsby Bend typically runs $2,800-$6,500 for a full encapsulation, with most river-bottom homes needing moisture control before any insulation goes in. The Colorado River corridor’s elevated humidity means we start every job by sealing the envelope, then insulating - never the reverse. Call (737) 259-8352 for a written price before any work starts.
We’re Envelope Insulation Co., independently owned and operated under The Haven Standard since 2016. Our crews serve Hornsby Bend from our Austin office, and we publish before-and-after blower-door numbers on every applicable job so you can verify the air-sealing result in a single figure. We’ve sealed and insulated over 9,000 homes, and every one began with a written price and ended with a documented photo record.
Why Hornsby Bend Homes Are Different
Hornsby Bend sits in the Colorado River bottomlands east of Austin, and that low-lying position creates a persistently humid microclimate that destroys fiberglass batt insulation faster than in the drier upland suburbs just a few miles west. We’ve pulled saturated batts from crawl spaces near the river that had compressed to half their labeled R-value in under five years.
The housing stock here is a mix of older rural ranch homes and manufactured housing, much of it built before Travis County adopted modern energy codes. Many structures have thin or absent attic insulation and completely uninsulated pier-and-beam foundations. As Austin’s eastward growth absorbs the area, we’re also working in converted agricultural outbuildings and early 2000s spec homes with code-minimum insulation that falls well short of current Austin Energy Green Building benchmarks. The manufactured homes near the river frequently suffer compromised belly-board insulation - the fiberglass blanket stapled beneath the floor - where bottomland moisture causes sagging, gaps, and mold that owners never see but always pay for in summer cooling bills.
Winter Storm Uri in February 2021 exposed another weakness: these older, under-insulated structures face bidirectional thermal stress from 100°F+ summers and sudden hard freezes, and they’re poorly equipped to handle either.
Our Main Hornsby Bend Services
Hornsby Bend homeowners call us most often for attic work and spray foam - here is what each job involves in this market.
Attic Insulation in Hornsby Bend
Most Hornsby Bend attics we enter have either original code-minimum fiberglass or nothing at all, especially in the ranch homes and manufactured housing that dominate the area. We start with a blower-door test to measure air leakage, then seal top plates and penetrations before adding any insulation. Attic Insulation in Hornsby Bend jobs here often include remediation for moisture-damaged existing material.
Spray Foam Insulation in Hornsby Bend
Closed-cell spray foam pays for itself faster in Hornsby Bend than in drier Travis County suburbs because it acts as both insulation and vapor retarder in one application. We use Icynene and Demilec products in river-bottom crawl spaces and rim joists where humidity control is critical. Spray Foam Insulation in Hornsby Bend is our recommendation for any pier-and-beam foundation with chronic moisture issues.
Blown-In Insulation in Hornsby Bend
Blown-in cellulose or fiberglass works well in Hornsby Bend’s older ranch homes with open attics and minimal obstructions, but only after air sealing is complete. We won’t blow insulation over an unsealed attic floor - that’s Haven Standard policy everywhere, and it’s especially important here where humid air leaks accelerate degradation. Blown-In Insulation in Hornsby Bend jobs include a documented photo record of the sealed deck before coverage.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Hornsby Bend
Crawl space encapsulation in Hornsby Bend addresses the single biggest building-envelope failure we see in this market: moisture from the Colorado River bottomlands rising through pier-and-beam foundations and destroying insulation from below. Many homes here have dirt-floored crawl spaces with no vapor barrier at all, or a thin 6-mil sheet that tore years ago. Crawl Space Encapsulation & Vapor Barrier is often the first step before any other insulation work can succeed in this climate.
Manufactured homes are particularly vulnerable. The belly-board insulation stapled beneath the floor sits inches from humid soil, and we’ve found sagging, gap-ridden blankets that owners didn’t know existed until we showed them the photo record.
Crawl Space Encapsulation
Signs you need it
Your floors feel cold in winter despite running the heat, you smell mustiness from vents or crawl space access points, or your energy bills spike every summer without explanation.
What it costs in Hornsby Bend
Full crawl space encapsulation in Hornsby Bend typically runs $2,800-$6,500 depending on square footage, existing moisture damage, and whether the foundation needs structural repairs before sealing.
How we do it
We install a reinforced polyethylene vapor barrier across the entire dirt floor, seal it to foundation walls, tape all seams, then close the space with rigid foam board on walls and a dehumidifier sized to the volume.
Crawl Space Vapor Barrier
Signs you need it
You see standing water after rains, white mineral deposits on block walls, or rusted ductwork and fasteners in the crawl space.
What it costs in Hornsby Bend
A standalone vapor barrier installation in Hornsby Bend runs $1,200-$2,800 for a typical 1,200-square-foot crawl space with accessible perimeter walls.
How we do it
We grade the dirt floor, lay 12-20 mil reinforced polyethylene with sealed overlaps, and mechanically fasten it to perimeter walls to create a continuous moisture break.
What Crawl Space Encapsulation & Vapor Barrier Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Full encapsulation (sealed walls, floor, dehumidifier) | $2,800 - $6,500 |
| Vapor barrier only (reinforced poly, dirt floor) | $1,200 - $2,800 |
| Crawl space insulation (rigid foam or closed-cell foam) | $1,800 - $4,200 |
Can I encapsulate just part of my crawl space?
Partial encapsulation traps moisture in unsealed areas and accelerates rot; we only perform full perimeter and floor sealing to maintain warranty coverage under our 365-Day Done Right Promise.
How long does crawl space encapsulation take in Hornsby Bend?
Most Hornsby Bend encapsulations take two to four days depending on access clearance and whether we need to remove degraded existing material first; you’ll get a written schedule with your price.
Radiant Barrier Installation in Hornsby Bend
Radiant barrier installation in Hornsby Bend targets the specific thermal stress of Central Texas: 100°F+ attic temperatures for months that overload air conditioning systems in homes with dark shingle roofs and minimal existing insulation. Many Hornsby Bend ranch homes and manufactured housing units have no radiant protection at all, and the cooling load shows up in July and August bills that never drop below $400. Radiant Barrier Installation reflects radiant heat rather than absorbing it, reducing attic temperatures by 20-35 degrees in our measurements.
Attic Radiant Barrier
Signs you need it
Your air conditioner runs continuously after 2 PM on sunny days, your attic feels like a furnace when you peek through the hatch, or your cooling bills exceed $300 in peak summer months.
What it costs in Hornsby Bend
Attic radiant barrier installation in Hornsby Bend typically costs $1,100-$2,400 for a 1,500-square-foot attic with standard pitch and clear access.
How we do it
We staple perforated aluminum foil across rafter bottoms or lay it over existing insulation, maintaining ventilation channels and avoiding compression that would reduce effectiveness.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing soon and want integrated radiant protection, or your current roof deck shows heat damage to underlayment from years of extreme attic temperatures.
What it costs in Hornsby Bend
Radiant barrier roof deck application during re-roofing in Hornsby Bend runs $1,800-$3,500 depending on roof complexity and whether we’re working with new decking or retrofitting existing.
How we do it
We apply reflective sheathing or foil-faced decking during roof replacement, sealing seams with aluminum tape to create a continuous thermal break at the roof plane.
What Radiant Barrier Installation Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Attic radiant barrier (foil, rafter or floor application) | $1,100 - $2,400 |
| Radiant barrier roof deck (during re-roofing) | $1,800 - $3,500 |
| Radiant barrier with attic air sealing package | $2,200 - $4,800 |
Does radiant barrier work with existing insulation?
Yes, radiant barrier complements rather than replaces insulation; we install it over existing fiberglass or cellulose after air sealing, and the combined system typically reduces cooling load by 15-25 percent in Hornsby Bend attics.
Can radiant barrier be installed in summer?
We work in attics year-round starting at 7 AM to beat peak temperatures, and perforated barriers actually help moderate attic heat immediately rather than trapping it.
Insulation Removal & Replacement in Hornsby Bend
Insulation removal and replacement in Hornsby Bend is often necessitated by the area’s humidity-driven degradation: fiberglass batts that have absorbed river-bottom moisture, compressed, and grown mold, or rodent-contaminated attics in older ranch homes with unsealed entry points. We’ve removed insulation from Hornsby Bend homes where the material weighed twice its dry weight from moisture alone. Insulation Removal & Replacement always includes air sealing before new material goes in - we will not replace over an unsealed deck.
Contaminated Insulation Removal
Signs you need it
You see dark staining, smell ammonia or mustiness in the attic, or find droppings and nesting material when checking storage areas.
What it costs in Hornsby Bend
Contaminated insulation removal in Hornsby Bend runs $1,500-$3,200 for a typical 1,200-square-foot attic including HEPA containment, disposal, and sanitizing of the deck.
How we do it
We establish negative air pressure with HEPA filtration, remove material in sealed bags, apply enzymatic sanitizer to the deck, and document the clean substrate with photos before any new insulation is specified.
Insulation Replacement
Signs you need it
Your insulation has compressed below the joist tops, shows water staining or mold, or was installed before 1990 and may contain vermiculite or other outdated materials.
What it costs in Hornsby Bend
Insulation replacement in Hornsby Bend typically costs $2,000-$4,500 for attic coverage to current Austin Energy Green Building benchmarks after removal of existing material.
How we do it
We remove existing material to the deck, seal all top plates and penetrations with foam and caulk, then install new insulation to the specified depth with a documented photo record of coverage uniformity.
What Insulation Removal & Replacement Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Contaminated insulation removal (attic, with sanitizing) | $1,500 - $3,200 |
| Insulation replacement (attic, to current benchmarks) | $2,000 - $4,500 |
| Full removal + replacement + air sealing package | $3,500 - $7,200 |
Do I have to leave during insulation removal?
You can stay in the home; we seal the attic access and establish negative pressure so no contamination enters living spaces, and we notify you before restarting HVAC systems.
How do I know if my old insulation is dangerous?
Pre-1990 vermiculite insulation may contain asbestos; we test a sample before disturbing it, and if positive, we refer to a licensed abatement contractor rather than handling it ourselves.
Attic Air Sealing in Hornsby Bend
Attic air sealing in Hornsby Bend is the foundational step we refuse to skip: the Colorado River bottomlands’ humidity means every unsealed penetration is a pathway for moist outside air to enter, condense on cool ductwork, and destroy insulation from within. We’ve measured 4,000+ CFM50 in Hornsby Bend ranch homes before sealing and cut that by half with top plate and penetration work alone. Attic Air Sealing is required before we add any insulation, and we publish the before-and-after blower-door numbers so you can verify the result.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from ceiling fixtures, see dust streaks around vent covers, or notice your attic insulation is darkened near interior walls from filtering airborne particles.
What it costs in Hornsby Bend
Top plate and penetration sealing in Hornsby Bend typically runs $800-$1,800 for a 1,500-square-foot home with standard interior wall density and accessible attic space.
How we do it
We locate every top plate, wire penetration, and plumbing stack with blower-door-directed diagnostics, then seal with expanding foam, fire-rated caulk, and rigid blocking where required by code.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in high winds, you feel conditioned air escaping around ceiling vents, or your energy auditor flagged thermal bypass at the duct boot connections.
What it costs in Hornsby Bend
Can light and duct boot sealing in Hornsby Bend costs $400-$1,200 depending on the number of fixtures and whether we need to install fire-rated covers over non-IC-rated housings.
How we do it
We install pre-formed fire-rated enclosures over can lights, seal duct boots with mastic and mesh, and verify each connection with smoke pencil testing during the blower-door run.
What Attic Air Sealing Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Top plate & penetration sealing | $800 - $1,800 |
| Can light & duct boot sealing | $400 - $1,200 |
| Full attic air sealing (comprehensive package) | $1,500 - $3,200 |
Can air sealing alone lower my bills?
Yes, we’ve seen 15-30 percent cooling load reduction from air sealing alone in Hornsby Bend’s leakiest homes, though we typically pair it with insulation for maximum performance.
How do you prove the sealing worked?
We run a blower-door test before and after, publish both numbers on your job record, and the reduction in CFM50 is your documented proof of a tighter envelope.
Wall Insulation in Hornsby Bend
Wall insulation in Hornsby Bend addresses the uninsulated or poorly insulated wall cavities common in ranch homes built before modern energy codes and manufactured housing with minimal cavity depth. Many Hornsby Bend homes have empty 2×4 walls with no insulation at all, or compressed fiberglass that settled decades ago. Wall Insulation in this market often means retrofitting existing structures rather than new construction, which limits the methods but not the results.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, you have no insulation when you remove an outlet cover, or your home was built before 1980 with hollow stud cavities.
What it costs in Hornsby Bend
Injection foam wall insulation in Hornsby Bend runs $3,500-$7,500 for a 1,500-square-foot home depending on cavity depth, exterior finish type, and whether we need to repair access holes.
How we do it
We drill 2-inch holes at stud-bay intervals, inject slow-rise foam that fills without bowing drywall, then plug and texture-match holes for paint-ready finish.
Drill & Fill Wall Insulation
Signs you need it
You want cellulose or fiberglass in existing walls rather than foam, or your budget requires a lower-cost retrofit with still-meaningful R-value improvement.
What it costs in Hornsby Bend
Drill-and-fill cellulose or fiberglass in Hornsby Bend walls typically costs $2,500-$5,500 for the same 1,500-square-foot footprint with standard 2×4 construction.
How we do it
We drill access holes, dense-pack cellulose or blow fiberglass to calculated density, then seal holes with matching plugs; we verify fill completeness with thermal imaging from inside.
What Wall Insulation Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Injection foam wall insulation (slow-rise, existing walls) | $3,500 - $7,500 |
| Drill & fill cellulose or fiberglass | $2,500 - $5,500 |
| Exterior wall insulation (remodel or re-siding opportunity) | $4,200 - $9,000 |
Will injection foam damage my walls?
We use slow-rise formulations specifically designed for existing walls, and we’ve completed thousands of injections without structural damage; your written scope specifies the product and pressure parameters.
Can you insulate walls without removing drywall?
Yes, both injection foam and drill-and-fill methods access cavities through small exterior or interior holes that we repair and texture-match, preserving your finished surfaces.
Attic Cleaning & Rodent Proofing in Hornsby Bend
Attic cleaning and rodent proofing in Hornsby Bend is frequently needed in the area’s older ranch homes and manufactured housing, where unsealed construction and mature trees create entry highways for squirrels, rats, and raccoons. We’ve found active infestations in Hornsby Bend attics where homeowners only noticed the smell after the damage was extensive. Attic Cleaning & Rodent Proofing includes full decontamination and exclusion - we don’t just trap and leave.
Attic Sanitizing & Decontamination
Signs you need it
You smell urine or decay from vents, see staining on ceiling drywall, or find droppings and nesting material when accessing stored items.
What it costs in Hornsby Bend
Attic sanitizing and decontamination in Hornsby Bend runs $1,200-$2,800 depending on contamination extent, attic square footage, and whether insulation removal is required before treatment.
How we do it
We remove contaminated material, apply enzyme-based sanitizer to all surfaces, fog with odor neutralizer, and run HEPA air scrubbers until particle counts drop to safe levels.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find chew marks around roof vents or soffits, or have had repeated trapping services that never stop new entry.
What it costs in Hornsby Bend
Rodent proofing and exclusion in Hornsby Bend typically costs $900-$2,200 for a single-story home with standard roof complexity and identifiable entry points.
How we do it
We inspect with cameras, seal every entry larger than 1/4 inch with rodent-proof materials, install chew-proof vent covers, and provide a written warranty on exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Hornsby Bend
| Item | Typical range in Hornsby Bend |
|---|---|
| Attic sanitizing & decontamination | $1,200 - $2,800 |
| Rodent proofing & exclusion | $900 - $2,200 |
| Full attic restoration (cleaning, proofing, re-insulation) | $3,500 - $8,500 |
How do I know rodents are gone before you re-insulate?
We set monitoring devices, seal all entries, and verify no new activity for a minimum period before installing new insulation; rushing this step traps live animals and voids our warranty.
Is rodent damage covered by homeowners insurance?
Most policies exclude rodent damage as gradual deterioration, but we document everything with photos for your adjuster and can provide a written scope if your policy has exceptions.
Home Energy Audit in Hornsby Bend
A home energy audit in Hornsby Bend gives you a prioritized roadmap for addressing the specific failures common in this market: air leakage from unsealed attics, moisture-driven insulation degradation in crawl spaces, and thermal bypass in walls that were never insulated to current standards. Our audits in Hornsby Bend consistently find that the worst-performing homes are losing 40-60 percent of conditioned air through the envelope. Home Energy Audit results include written recommendations with prices for each measure, ranked by cost-effectiveness.
Blower Door Test
Signs you need it
Your energy bills seem high for your home size, you feel drafts you can’t locate, or you’re planning major insulation work and want a baseline to measure improvement against.
What it costs in Hornsby Bend
A standalone blower-door test in Hornsby Bend costs $300-$500, or it’s included at no additional charge when bundled with our full home energy audit package.
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 quantify envelope tightness.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation behind walls, want to verify recent insulation work, or need to locate air leaks that aren’t visible to the eye.
What it costs in Hornsby Bend
Thermal imaging inspection in Hornsby Bend runs $250-$450 as a standalone service, or it’s integrated into our full audit at reduced bundled pricing.
How we do it
We scan the building envelope with a FLIR camera during blower-door depressurization to make air leakage visible as temperature differentials, then mark problem areas on a floor plan you keep.
