Insulation in Marble Falls, TX
Crawl space encapsulation and vapor barrier installation in Marble Falls typically runs $3,500-$7,500 for a full encapsulation, with vapor barrier-only jobs starting around $1,800. Most Marble Falls homes we work on sit on pier-and-beam foundations over limestone terrain, where ground moisture and seasonal humidity swings make unsealed crawl spaces a year-round problem. Call (254) 970-2136 for a written price before any work starts.
We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite, not an upsell. In Marble Falls, that means we seal top plates, can lights, and penetrations before we add a single inch of insulation. Every applicable job gets before-and-after blower-door numbers so you can see the performance change you paid for.
Why Marble Falls Homes Are Different
Marble Falls has boomed as a Highland Lakes retirement and second-home destination, filling the surrounding hillsides and lakefront with post-2000 builds designed for views rather than thermal performance. Vaulted ceilings, large west- and south-facing windows, and builder-grade insulation envelopes are the norm. Winter Storm Uri exposed exactly how unprepared Burnet County’s housing stock is for hard freezes, while 100°F+ Hill Country summers hammer the same homes from the other direction.
The city’s core holds modest 1950s-1970s in-town homes, many with original fiberglass batts or no wall insulation at all. The surrounding growth belt is dominated by post-2000 custom and semi-custom builds on rocky limestone and granite terrain, often pier-and-beam or engineered slabs, where crawl spaces and vaulted great rooms are common insulation problem areas. A large share of these newer homes were purchased as seasonal lake retreats and are now occupied full-time, meaning their original insulation specs were never designed for year-round comfort.
At roughly 1,400 ft elevation, Marble Falls sees bare limestone and Granite Mountain amplify radiant heat, with daytime temperatures routinely exceeding 100°F from June through August. The same topography funnels Arctic air during rare but severe freezes. Metal roofs, extremely common for Hill Country aesthetics, turn attic spaces into radiant ovens. Crews working lakefront subdivisions off RR 1431 and FM 2147 consistently find open-concept vaulted ceilings meeting metal roofs with no radiant barrier create attic temps above 160°F in July.
Our Main Marble Falls Services
Marble Falls homeowners call us most often about attic performance and whole-home air sealing. Here are the three services with dedicated local pages:
Attic Insulation in Marble Falls
Attic insulation in Marble Falls means dealing with metal-roof radiant heat gain and the gap between builder-grade R-values and what the Hill Country actually demands. We measure existing depth, check for compression or moisture damage, and specify Owens Corning or Johns Manville products matched to your roof assembly. Every attic job starts with air sealing, and we deliver a written price before anyone lifts a tool. Attic Insulation in Marble Falls covers our full process and pricing.
Spray Foam Insulation in Marble Falls
Spray foam insulation in Marble Falls solves the radiant-oven problem that blown fiberglass cannot touch, especially in vaulted ceilings under metal roofs. We use open-cell and closed-cell Icynene and Demilec products, selected by application, never by what’s cheapest to stock. Closed-cell on roof decks stops radiant heat transfer at the source. Spray Foam Insulation in Marble Falls details when foam is the right choice versus other assemblies.
Blown-In Insulation in Marble Falls
Blown-in insulation in Marble Falls works well for flat attics with adequate air sealing already in place, but we will not blow GreenFiber or fiberglass over an unsealed attic floor. Standard blown fiberglass loses meaningful R-value above 160°F attic temps, so we always assess whether a radiant barrier or spray foam conversion is the real conversation. Blown-In Insulation in Marble Falls explains our assessment process.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Marble Falls
Marble Falls’ pier-and-beam homes on limestone terrain create crawl spaces that breathe ground moisture year-round, and the seasonal humidity swings between 100°F summers and hard freezes mean unsealed crawl spaces suffer condensation cycles that rot floor joists and grow mold. Crawl Space Encapsulation & Vapor Barrier is our primary service here because it’s the one that stops the damage at its source.
We see three patterns in Marble Falls: 1950s-1970s in-town homes with dirt crawl spaces and no vapor barrier; post-2000 lake homes with thin 6-mil plastic that tore during construction; and seasonal retreats converted to full-time use where the original minimal specs are now overwhelmed by daily occupancy.
Crawl Space Vapor Barrier
Signs you need it
Your floors feel cold in winter despite running the heat, or you smell mustiness rising from below the subfloor.
What it costs in Marble Falls
A ground-only vapor barrier in a typical Marble Falls crawl space runs $1,800-$3,200 depending on square footage and access.
How we do it
We remove debris, grade the soil for drainage, lay 10-20 mil reinforced polyethylene with sealed seams, and extend it 6 inches up pier walls, finishing with mechanical fasteners and mastic.
Crawl Space Encapsulation
Signs you need it
You see standing water after rain, mold on floor joists, or your HVAC ducts in the crawl space are sweating and losing efficiency.
What it costs in Marble Falls
Full encapsulation with sealed vapor barrier, insulated walls, and conditioned air supply typically ranges $3,500-$7,500 in Marble Falls.
How we do it
We install a complete vapor barrier sealed to foundation walls, apply closed-cell foam or rigid insulation to walls, seal all vents, and add a dehumidifier or supply air connection per the home’s HVAC layout.
What Crawl Space Encapsulation & Vapor Barrier Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Ground vapor barrier (6-mil to 20-mil) | $1,800 - $3,200 |
| Full encapsulation with wall insulation | $3,500 - $7,500 |
| Encapsulation with dehumidifier | $5,000 - $9,000 |
How long does crawl space encapsulation take in Marble Falls?
Most vapor barrier jobs finish in one day; full encapsulation takes two to three days depending on access and whether we need to address existing moisture damage. We give you a written schedule with the price.
Will encapsulation help with winter floor temperatures?
Yes, sealing the crawl space stops the cold air infiltration that makes pier-and-beam floors feel frigid during Marble Falls freezes, and the insulated envelope keeps heated air from escaping downward. Call (254) 970-2136 for a free assessment.
Radiant Barrier Installation in Marble Falls
Radiant barrier installation in Marble Falls is not a luxury add-on; it’s a thermal survival tool for homes with metal roofs or west-facing vaulted ceilings that see attic temps above 160°F. The Hill Country’s bare limestone and granite amplify solar gain, and standard insulation assemblies were never designed for that radiant load. Radiant Barrier Installation is the service we recommend most often after inspecting post-2000 lake homes.
Attic Radiant Barrier
Signs you need it
Your attic feels like a furnace by noon, your AC runs continuously from 2-7 PM, or your second floor is 8-12 degrees hotter than the first.
What it costs in Marble Falls
Radiant barrier installation in a typical Marble Falls attic runs $1,500-$3,500 depending on roof complexity and whether we combine it with air sealing.
How we do it
We staple perforated radiant barrier foil across attic truss bottoms or drape it over existing insulation, maintaining ventilation channels and avoiding compression that would reduce its reflective performance.
Radiant Barrier Roof Deck
Signs you need it
You have a metal roof with no attic ventilation strategy, or you’re re-roofing and want to address radiant gain at the source rather than treating symptoms.
What it costs in Marble Falls
Roof-deck radiant barrier applied during construction or re-roofing typically ranges $2,000-$4,500 in Marble Falls.
How we do it
We apply radiant barrier sheathing or foil directly to the roof deck underside, sealing seams and integrating with ridge and soffit ventilation to maintain airflow while blocking 95% of radiant heat transfer.
What Radiant Barrier Installation Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Attic radiant barrier (foil over truss) | $1,500 - $3,500 |
| Radiant barrier roof deck application | $2,000 - $4,500 |
| Radiant barrier with full air sealing | $3,000 - $6,000 |
Does radiant barrier work with existing blown-in insulation?
Yes, we install radiant barrier over existing insulation without removing it, though we always air seal first so the combined assembly performs as designed. Call (254) 970-2136 for a written price.
How much cooler will my attic get?
A properly installed radiant barrier typically reduces attic temperature by 20-35°F in Marble Falls homes with metal or dark shingle roofs, measured with our infrared camera at final walkthrough.
Insulation Removal & Replacement in Marble Falls
Insulation removal and replacement in Marble Falls addresses two distinct housing eras: 1950s-1970s homes with degraded fiberglass batts, compressed cellulose, or no wall insulation at all, and post-2000 lake homes where seasonal occupancy masked inadequate specs now failing under full-time use. Water intrusion from ice dams during Uri and chronic summer humidity have contaminated much of the existing stock. Insulation Removal & Replacement starts with a contamination assessment and written disposal plan.
Contaminated Insulation Removal
Signs you need it
You see water staining on ceiling drywall, smell mold when the HVAC runs, or find rodent droppings and nesting material in the attic.
What it costs in Marble Falls
Contaminated insulation removal and disposal in Marble Falls typically runs $2,000-$4,500 depending on square footage and hazard level.
How we do it
We set up negative air containment, remove contaminated material with HEPA-filtered vacuums, bag it for proper disposal, and sanitize substrate surfaces before any new insulation goes in.
Insulation Replacement
Signs you need it
Your insulation is compressed below its labeled R-value, has settled more than 25% from original depth, or was installed before 1990 with unknown material composition.
What it costs in Marble Falls
Full insulation replacement with new blown-in or batt product in a typical Marble Falls home ranges $3,500-$8,000.
How we do it
We remove old material, air seal all penetrations, and install new Owens Corning or Johns Manville insulation to current IECC standards for Burnet County’s climate zone, with depth markers and a photo record.
What Insulation Removal & Replacement Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Contaminated insulation removal | $2,000 - $4,500 |
| Standard insulation removal (non-hazardous) | $1,200 - $2,800 |
| Insulation replacement (full attic) | $3,500 - $8,000 |
Do I have to leave during insulation removal?
No, our containment systems keep living spaces isolated, though we recommend sensitive individuals plan to be out during active removal of heavily contaminated material. Call (254) 970-2136 to discuss your specific situation.
How do I know if my old insulation is hazardous?
We test for asbestos in pre-1990 vermiculite and assess mold contamination with air sampling; you get written results before we proceed with removal or replacement.
Attic Air Sealing in Marble Falls
Attic air sealing in Marble Falls is the single highest-ROI improvement for homes struggling with summer cooling loads and winter freeze damage, yet it’s the step most contractors skip. The Hill Country’s thermal swings, from 100°F+ days to sub-zero freezes, force enormous pressure differentials across the ceiling plane, and every unsealed penetration is a pathway for conditioned air to escape. Attic Air Sealing is always our first move, never an upsell.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at ceiling outlets or light switches, or your blower-door test shows excessive leakage at the attic floor.
What it costs in Marble Falls
Top plate and penetration sealing in a typical Marble Falls attic runs $1,200-$2,800 as a standalone service, or it’s included before any insulation upgrade.
How we do it
We seal all top plate joints, wire penetrations, plumbing stacks, and chimney chases with fire-rated caulk and foam, then verify with a blower-door test to measure the reduction in CFM50.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in wind, you see dust streaks around ceiling fixtures, or rooms farthest from the HVAC unit never reach set temperature.
What it costs in Marble Falls
Can light sealing with proper covers and duct boot sealing typically adds $800-$1,800 to an attic air sealing job in Marble Falls.
How we do it
We install fire-rated airtight covers over can lights, seal duct boots with mastic and mesh, and pressure-test the duct system to confirm no post-sealing leakage.
What Attic Air Sealing Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Basic attic air sealing (top plates, penetrations) | $1,200 - $2,800 |
| Comprehensive sealing with can lights and ducts | $2,000 - $4,500 |
| Air sealing with blower-door verification only | $800 - $1,500 |
Can air sealing alone lower my electric bill?
Yes, a proper attic air seal typically reduces heating and cooling loads by 15-25% in Marble Falls homes, verified by before-and-after blower-door numbers we provide in writing.
Is air sealing required before adding insulation?
We will not install new insulation over an unsealed attic floor; it’s our hard prerequisite because blown material hides leaks and makes them impossible to address later without full removal. Call (254) 970-2136 for a written scope.
Wall Insulation in Marble Falls
Wall insulation in Marble Falls means confronting the reality that many 1950s-1970s in-town homes have empty stud cavities or original fiberglass batts that have settled and degraded, while post-2000 builds often used minimal cavity fill to cut costs on seasonal retreats. The Hill Country’s freeze-thaw cycles create convection currents in uninsulated walls that make rooms feel drafty even when windows are closed. Wall Insulation addresses this with methods that don’t require tearing out drywall.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel cold to the touch in winter, or you have rooms with two exterior walls that are consistently 5-10 degrees cooler than interior rooms.
What it costs in Marble Falls
Injection foam wall insulation for a typical 1,500-2,500 sq ft Marble Falls home runs $3,500-$7,500 depending on cavity depth and access.
How we do it
We drill 5/8-inch holes through exterior siding or mortar joints, inject slow-rise foam to fill cavities completely, and plug with matching material, leaving no visible trace on most surfaces.
Drill & Fill Wall Insulation
Signs you need it
You have settled cellulose or fiberglass in walls with gaps at the top of studs, or you’re remodeling and want to insulate before closing up.
What it costs in Marble Falls
Drill and fill with dense-pack cellulose in Marble Falls typically ranges $2,500-$5,500 for a whole-house application.
How we do it
We remove minimal siding, drill at stud bay intervals, blow GreenFiber dense-pack cellulose to 3.5 lbs per cubic foot to prevent settling, and seal penetrations with weatherproof plugs.
What Wall Insulation Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Injection foam (whole house) | $3,500 - $7,500 |
| Drill & fill dense-pack cellulose | $2,500 - $5,500 |
| Exterior wall insulation (new construction) | $1,800 - $4,000 |
Will injection foam damage my walls?
No, slow-rise foam is specifically formulated not to bow studs or crack drywall; we monitor pressure during injection and have completed thousands of retrofits without structural damage. Call (254) 970-2136 for a free assessment.
Can you insulate walls without removing drywall?
Yes, both injection foam and drill-and-fill methods access wall cavities from the exterior, leaving interior finishes completely undisturbed.
Attic Cleaning & Rodent Proofing in Marble Falls
Attic cleaning and rodent proofing in Marble Falls addresses a problem amplified by the area’s oak-juniper woodland interface: squirrels, raccoons, and roof rats exploit the same unsealed penetrations that leak conditioned air, contaminating insulation with droppings and urine while compressing it with nesting activity. Post-2000 homes with complex rooflines and inadequate soffit screening are especially vulnerable. Attic Cleaning & Rodent Proofing restores the space and keeps it protected.
Attic Sanitizing & Decontamination
Signs you need it
You hear scratching at night, find droppings in the attic, or smell ammonia when the HVAC pulls attic air through ceiling leaks.
What it costs in Marble Falls
Attic sanitizing and decontamination in Marble Falls typically runs $1,500-$3,500 depending on contamination extent and attic square footage.
How we do it
We remove contaminated insulation, apply enzymatic cleaner to break down organic waste, HEPA-vacuum all surfaces, and treat with disinfectant before installing new insulation.
Rodent Proofing & Exclusion
Signs you need it
You’ve had repeated pest control treatments but animals keep returning, or you see chew marks around soffit vents and roof penetrations.
What it costs in Marble Falls
Rodent proofing and exclusion for a typical Marble Falls home ranges $1,200-$2,800, with annual inspection plans available.
How we do it
We seal all entry points 1/4-inch and larger with rodent-proof materials, install chew-resistant vent screening, and provide a written exclusion map showing every access point addressed.
What Attic Cleaning & Rodent Proofing Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Attic sanitizing & decontamination | $1,500 - $3,500 |
| Rodent proofing & exclusion | $1,200 - $2,800 |
| Full attic restoration (cleaning + proofing + re-insulation) | $4,500 - $9,000 |
How do I know if rodents have damaged my insulation?
We photograph every attic and show you compression patterns, tunneling, and contamination zones; if the insulation is compromised, we include replacement in the written scope. Call (254) 970-2136 for an inspection.
Does rodent proofing include trapping?
We partner with licensed wildlife operators for active infestations; our work begins after removal, ensuring animals cannot re-enter through the same gaps they used before.
Home Energy Audit in Marble Falls
A home energy audit in Marble Falls gives you a documented baseline for every decision about your building envelope, especially critical in a market where homes face both 160°F attic summers and sub-zero freezes. The audit identifies whether your money should go to air sealing, insulation, radiant barrier, or equipment right-sizing, in that priority order. Home Energy Audit is where we start when a homeowner says “my bills are too high” but doesn’t know why.
Blower Door Test
Signs you need it
Your home feels drafty, rooms have uneven temperatures, or you’ve added insulation but bills didn’t drop as expected.
What it costs in Marble Falls
A standalone blower-door test in Marble Falls runs $350-$650, or it’s included in our comprehensive audit package.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 to quantify total envelope leakage and identify the largest leak paths with smoke pencils and infrared.
Thermal Imaging Inspection
Signs you need it
You suspect missing insulation in walls or vaulted ceilings, or you want to verify contractor work from a previous job.
What it costs in Marble Falls
Thermal imaging as part of a full audit typically adds $200-$400 to the base blower-door test in Marble Falls.
How we do it
We scan every interior and exterior surface with a FLIR camera during controlled conditions, marking thermal bridges, insulation voids, and moisture intrusion on a digital report with temperature differentials.
What Home Energy Audit Costs in Marble Falls
| Item | Typical range in Marble Falls |
|---|---|
| Blower-door test only | $350 - $650 |
| Comprehensive audit (blower door + thermal + duct test) | $600 - $1,200 |
| Audit with written scope and priority list | $800 - $1,500 |
Will an audit tell me what to fix first?
Yes, you receive a written priority list ranked by cost-effectiveness, with estimated savings for each measure, so you can phase work according to your budget. Call (254) 970-2136 to schedule.
How long does a home energy audit take?
A comprehensive audit takes 3-4 hours for a typical Marble Falls home, including setup, testing, and a walkthrough where we show you real-time thermal images and explain findings.
