Insulation in Wells Branch, TX
Most Wells Branch homes need insulation work because the original 1985-1995 fiberglass batts have settled well below modern standards, and attic temperatures here regularly top 150°F in summer. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite - not an upsell - on every job. Call (737) 259-8352 for a written price before any work starts.
Why Wells Branch Homes Are Different
Wells Branch is a master-planned community built out almost entirely between roughly 1985 and 1995, meaning virtually every home shares the same aging fiberglass-batt attic insulation installed to minimal code standards of that era - now 30-40 years old, compacted, and far below today’s IECC Zone 2 recommendation of R-49. Unlike neighboring Austin, Wells Branch sits in unincorporated Travis County and was never retroactively required to upgrade, leaving nearly the entire community with the same insulation deficit simultaneously.
The housing stock is dominated by single-story and two-story slab-on-grade brick-veneer wood-frame homes. Slab foundations eliminate crawl-space concerns, shifting virtually all insulation work to attics where original R-19 fiberglass batts have settled and shifted. Summer attic temperatures routinely exceed 150°F, and commercial development along Parmer Lane and US-183 amplifies the heat-island effect. The February 2021 Winter Storm Uri also exposed how thin insulation provides almost no buffer during hard freezes.
Because Wells Branch homes were developed by a small number of builders working from similar floor plans, a technician pulling attic access on one street can predict what they’ll find nearby - 3.5 inches of settled pink fiberglass over a thin radiant barrier stapled to rafters, a combination that leaves utility bills 20-30% higher than they should be.
Our Main Wells Branch Services
These are the two services Wells Branch homeowners call about most, plus blown-in for quick attic upgrades.
Attic Insulation in Wells Branch
Attic insulation in Wells Branch almost always means removing compacted R-19 fiberglass from the 1985-1995 build era and installing R-38 to R-49 blown-in cellulose or fiberglass, or upgrading to open-cell spray foam on the roof deck for conditioned attic space. We air seal first - top plates, can lights, penetrations - then insulate, with before-and-after blower-door numbers published on every job. Attic Insulation in Wells Branch covers full project details and pricing.
Spray Foam Insulation in Wells Branch
Spray foam insulation in Wells Branch is the upgrade homeowners choose after Winter Storm Uri or when the attic is being converted to conditioned space. Open-cell Icynene or Demilec foam applied to the roof deck at 5-7 inches delivers R-38 and creates a sealed envelope that fiberglass cannot match. We publish blower-door readings before and after so you see the air-leakage reduction in CFM50. Spray Foam Insulation in Wells Branch has full specifications.
Blown-In Insulation in Wells Branch
Blown-in insulation in Wells Branch is the fastest path from settled R-19 to code-compliant R-38 or R-49, typically completed in one day without removing the old batts if they’re clean. We use Owens Corning AttiCat fiberglass or GreenFiber cellulose, blown to depth marks we photograph for your record. Air sealing happens first - always - then we blow to uniform density with no gaps. Blown-In Insulation in Wells Branch explains material options and costs.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Wells Branch
Crawl space encapsulation and vapor barrier work in Wells Branch is limited because the neighborhood’s slab-on-grade construction eliminates most crawl spaces. Where crawl spaces do exist - primarily in a few custom builds and additions near the Wells Branch Greenbelt - they suffer from the same clay-soil moisture and summer humidity that affects all of Travis County. We approach Crawl Space Encapsulation & Vapor Barrier with the same sealed-first protocol: stop the water and air intrusion, then condition the space.
Crawl Space Vapor Barrier
Signs you need it
Standing water on the vapor barrier, white mineral efflorescence on block walls, or a musty smell that enters the living space through floor registers indicate the existing 6-mil poly has failed.
What it costs in Wells Branch
Vapor barrier replacement in Wells Branch crawl spaces runs $1,800-$3,200 for 800-1,200 square feet, including seam sealing and wall attachment.
How we do it
We remove the old poly, install a new 12-mil reinforced vapor barrier with sealed seams and mechanical fastening to walls, then verify with a moisture meter reading below 60% relative humidity.
Crawl Space Encapsulation
Signs you need it
Rotting floor joists, mold on subflooring, or insulation falling from the floor cavity mean uncontrolled moisture is destroying the structure from below.
What it costs in Wells Branch
Full encapsulation in Wells Branch starts at $4,500 for small crawl spaces and ranges to $8,500 for larger or conditioned-space conversions with dehumidifier installation.
How we do it
We seal all vents, install a 20-mil reinforced liner on walls and floor, seal penetrations with closed-cell foam, and add a dedicated dehumidifier with condensate pump to maintain below 55% RH.
What Crawl Space Encapsulation & Vapor Barrier Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Crawl space vapor barrier (12-mil, 800-1,200 sq ft) | $1,800 - $3,200 |
| Full crawl space encapsulation with dehumidifier | $4,500 - $8,500 |
| Crawl space insulation (foam board + vapor barrier) | $2,200 - $4,000 |
Do Wells Branch homes even have crawl spaces?
Most don’t - the neighborhood’s slab-on-grade construction eliminates them. Where they exist, typically in custom builds near the greenbelt, moisture problems are severe and need immediate attention. Call (737) 259-8352 and we’ll verify your foundation type during scheduling.
How long does crawl space encapsulation take in Wells Branch?
Two to four days for full encapsulation, one day for vapor barrier replacement alone. We deliver a written scope and warranty before starting, and photo documentation when we finish.
Radiant Barrier Installation in Wells Branch
Radiant barrier installation in Wells Branch addresses a specific local failure mode: the original 1985-1995 construction included thin, stapled foil radiant barriers that have torn, oxidized, or been buried under settled insulation, losing their reflective capacity. With attic temperatures exceeding 150°F and the Parmer Lane corridor amplifying summer heat loads, a properly installed radiant barrier can reduce attic heat gain by 20-30% and cut cooling runtime measurably. We install Radiant Barrier Installation systems that outperform the original builder-grade product.
Attic Radiant Barrier
Signs you need it
Torn or oxidized foil visible between rafters, or attic temperatures above 140°F on 95°F days while the AC runs continuously, indicate the original barrier has failed.
What it costs in Wells Branch
Attic radiant barrier installation in Wells Branch runs $1,200-$2,400 for a typical 1,800-2,400 square foot home, depending on roof pitch and accessibility.
How we do it
We install perforated radiant barrier foil across the bottom of rafters with an air gap above, or apply radiant barrier paint to the roof deck, ensuring no contact with insulation that would conduct heat.
Radiant Barrier Roof Deck
Signs you need it
Shingle temperatures causing premature granule loss, or rooms with cathedral ceilings that stay 10°F hotter than the rest of the house, suggest roof-deck heat transfer is overwhelming the cooling system.
What it costs in Wells Branch
Roof-deck radiant barrier application in Wells Branch costs $1,800-$3,200 when combined with air sealing, or $2,500-$4,500 with spray foam insulation for a conditioned attic assembly.
How we do it
We apply radiant barrier paint or foil-faced sheathing to the roof deck interior, maintaining the required 3/4-inch air gap, then verify attic temperature reduction with infrared imaging.
What Radiant Barrier Installation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic radiant barrier (foil, rafter-attached) | $1,200 - $2,400 |
| Radiant barrier roof deck with air sealing | $1,800 - $3,200 |
| Conditioned attic with spray foam + radiant barrier | $2,500 - $4,500 |
Does radiant barrier work with my existing insulation in Wells Branch?
Yes, but only if the original torn foil is removed or covered and the new barrier maintains an air gap. We inspect first and include the removal in your written scope. Call (737) 259-8352 for a free estimate.
How much cooler will my attic get with a radiant barrier?
Expect 20-30°F reduction in peak attic temperature, which translates to shorter AC cycles and lower peak demand. We measure before and after with infrared cameras and include the images in your photo record.
Insulation Removal & Replacement in Wells Branch
Insulation removal and replacement in Wells Branch is our most common starting point because the original 1985-1995 fiberglass batts have compressed from 6 inches to 3.5 inches, lost R-value, and often harbor rodent debris or moisture staining from roof leaks. Unlike newer neighborhoods with mixed housing ages, Wells Branch presents a predictable pattern: every third attic we open contains the same pink fiberglass, the same thin radiant barrier, and the same air-leakage path through top plates and can lights. We handle Insulation Removal & Replacement with HEPA containment and documented disposal.
Attic Insulation Removal
Signs you need it
Insulation compressed below the joist tops, visible water stains, or a history of roof leaks that soaked the fiberglass means removal is necessary before new material can perform.
What it costs in Wells Branch
Attic insulation removal in Wells Branch runs $1.50-$3.00 per square foot, or $2,700-$5,400 for a typical 1,800-square-foot attic, including HEPA vacuuming and bagged disposal.
How we do it
We set up negative-air containment, remove all old material with industrial HEPA vacuums, dispose at licensed facilities, and inspect the deck for leaks or mold before any new insulation goes in.
Contaminated Insulation Removal
Signs you need it
Strong ammonia smell, rodent droppings visible on the attic floor, or fiberglass with dark staining from urine saturation requires full removal and sanitization before re-insulation.
What it costs in Wells Branch
Contaminated insulation removal in Wells Branch starts at $3.50 per square foot and ranges to $6.00 per square foot for heavy rodent damage with deck replacement, typically $6,300-$10,800.
How we do it
We remove all contaminated material under negative pressure, apply enzyme-based sanitizing agent to the deck and joists, install new baffles and air sealing, then blow fresh insulation to R-38 or R-49.
What Insulation Removal & Replacement Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Standard attic insulation removal (HEPA, disposal) | $2,700 - $5,400 |
| Contaminated insulation removal + sanitization | $6,300 - $10,800 |
| Removal + replacement with R-49 blown-in | $5,500 - $9,500 |
Can you remove insulation without making a mess in my Wells Branch home?
Yes - we use negative-air containment and HEPA filtration, with access through the attic hatch only. Your living space stays sealed. Call (737) 259-8352 to schedule; estimates are free.
Do I have to remove old insulation before adding new?
Not if it’s clean and dry - we can blow over it. But Wells Branch attics with 30-40-year-old fiberglass usually have compression, staining, or rodent activity that makes removal the better investment. We inspect and give you a written recommendation.
Attic Air Sealing in Wells Branch
Attic air sealing in Wells Branch is the single most cost-effective improvement for homes built 1985-1995 because the original construction left top plates, wire penetrations, and can lights completely unsealed, creating a direct chimney effect between conditioned space and the 150°F attic. We never blow insulation over an unsealed attic floor - it’s our hard rule. Attic Air Sealing is always step one, with blower-door verification before and after so you see the CFM50 reduction you paid for.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling outlets, rooms that are 5-10°F different from the thermostat reading, or a blower-door test showing 4,000+ CFM50 on a 2,000-square-foot home indicate massive top-plate leakage.
What it costs in Wells Branch
Top plate and penetration sealing in Wells Branch runs $800-$1,800 for a typical home, depending on the number of interior walls and electrical penetrations.
How we do it
We access the attic floor, seal every top plate joint with acoustic sealant and rigid foam, foam all wire and pipe penetrations, and retest with the blower door to confirm reduction.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that flicker in high wind, or supply ducts that blow 85°F air in summer because they’re drawing attic heat through gaps at the boot connection, mean conditioned air is leaking out and attic air is leaking in.
What it costs in Wells Branch
Can light sealing with fire-rated covers and duct boot sealing in Wells Branch costs $400-$1,200, depending on the number of fixtures and accessibility.
How we do it
We install pre-formed fire-rated covers over each can light, seal with high-temperature caulk, then mastic-seal every duct boot to the drywall and insulate the boot with sleeve insulation.
What Attic Air Sealing Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Top plate & penetration sealing | $800 - $1,800 |
| Can light & duct boot sealing | $400 - $1,200 |
| Full attic air sealing with blower-door test | $1,500 - $3,500 |
Will air sealing alone lower my Wells Branch electric bill?
Yes - typically 10-20% reduction in cooling costs, verified by our before-and-after blower-door numbers. We publish the CFM50 reduction on every job. Call (737) 259-8352 for a free estimate.
Do you seal before or after adding insulation?
Always before - we will never blow insulation over an unsealed attic floor. Sealing first prevents the new insulation from becoming a filter that traps attic dust in your living space.
Wall Insulation in Wells Branch
Wall insulation in Wells Branch addresses a specific gap: the 1985-1995 construction used minimal cavity insulation, often R-11 fiberglass batts in 2×4 walls that have settled or been compromised by electrical retrofits. Because these homes share similar floor plans, we know which walls are exterior, which have plumbing chases that create thermal bypasses, and where the original builders skimped on insulation at corners and T-walls. Wall Insulation retrofits are completed from the exterior or through strategic interior access with minimal finish repair.
Injection Foam Wall Insulation
Signs you need it
Walls that are hot to the touch in summer, rooms with exterior walls that never cool evenly, or a blower-door test showing significant envelope leakage through the wall plate indicate empty or failed cavity insulation.
What it costs in Wells Branch
Injection foam wall insulation in Wells Branch runs $3.50-$6.00 per square foot of wall area, or $4,200-$7,200 for a typical 1,800-square-foot home with 1,200 square feet of exterior wall.
How we do it
We drill 5/8-inch holes through the exterior siding or interior drywall at stud-bay spacing, inject slow-rise foam to fill the cavity without bowing the studs, then patch and match finish.
Drill & Fill Wall Insulation
Signs you need it
Knob-and-tube wiring remnants, vermiculite insulation, or walls with no insulation at all - common in garage-to-room conversions or additions - require a drill-and-fill approach with material matched to the cavity condition.
What it costs in Wells Branch
Drill and fill with cellulose or fiberglass in Wells Branch costs $2.50-$4.50 per square foot, or $3,000-$5,400 for typical exterior walls, with asbestos or vermiculite abatement quoted separately.
How we do it
We drill access holes, inspect the cavity with a borescope for obstructions or hazardous materials, blow cellulose or fiberglass to density, and seal each hole with matching plug or spackle.
What Wall Insulation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Injection foam (exterior walls, typical home) | $4,200 - $7,200 |
| Drill & fill with cellulose or fiberglass | $3,000 - $5,400 |
| Interior wall soundproofing (Rockwool or CertainTeed) | $2,800 - $5,000 |
Can you insulate walls without tearing off drywall in Wells Branch?
Yes - injection foam and drill-and-fill both work through small holes that we patch and match. Most Wells Branch homes need 20-30 holes total, not full demolition. Call (737) 259-8352 for an exact scope and price.
Does wall insulation help with sound from Parmer Lane traffic?
Moderately - for significant noise reduction we use Rockwool or CertainTeed dense-pack in interior walls facing the road, which adds STC rating without the full cost of exterior wall retrofit.
Attic Cleaning & Rodent Proofing in Wells Branch
Attic cleaning and rodent proofing in Wells Branch is frequently the first step before insulation work because 30-40-year-old fiberglass batts provide nesting material, and the neighborhood’s mature oak canopy and greenbelt corridors support active squirrel, rat, and mouse populations. We find droppings, tunnels, and urine-compacted insulation in roughly one-third of Wells Branch attics we inspect. Attic Cleaning & Rodent Proofing is completed with enzyme sanitization and photo documentation before any new insulation is considered.
Attic Sanitizing & Decontamination
Signs you need it
Ammonia smell detectable at the attic hatch, visible droppings concentrated near the chimney or vent stacks, or fiberglass with dark staining from urine saturation require full decontamination before re-insulation.
What it costs in Wells Branch
Attic sanitizing and decontamination in Wells Branch runs $1,200-$2,800 for a typical 1,500-square-foot attic, including HEPA vacuuming, enzyme treatment, and odor neutralization.
How we do it
We remove all contaminated material under negative pressure, apply enzyme-based sanitizer to all structural surfaces, fog the attic with odor neutralizer, and provide a photo record of the clean deck before any new work begins.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in walls at dawn or dusk, chewed wires visible in the attic, or recurring droppings after previous trapping indicate entry points that haven’t been sealed.
What it costs in Wells Branch
Rodent proofing and exclusion in Wells Branch costs $800-$2,200 for a typical home, depending on roof complexity and the number of entry points found during inspection.
How we do it
We inspect the roofline, soffits, vents, and foundation with a borescope, seal all entry points 1/4-inch and larger with steel mesh and copper wool, install vent guards, and provide a written warranty on the exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic sanitizing & decontamination | $1,200 - $2,800 |
| Rodent proofing & exclusion | $800 - $2,200 |
| Full attic restoration (cleaning + proofing + re-insulation) | $4,500 - $8,500 |
How do I know if rodents have damaged my Wells Branch attic insulation?
Look for tunnel-shaped paths through fiberglass, concentrated droppings near warm stacks, or a sharp ammonia smell. We inspect with cameras and show you the footage before quoting. Call (737) 259-8352 - estimates are free.
Will rodents come back after you seal the entry points?
Not through the same holes - our steel mesh and copper wool exclusion carries a written warranty. We also identify secondary attractants like tree branches touching the roofline that need trimming.
Home Energy Audit in Wells Branch
Home energy audit in Wells Branch is the diagnostic starting point for homeowners who want to see exactly where their 1985-1995 home is losing conditioned air before committing to any insulation scope. Because every home in the neighborhood shares similar construction, our audit findings are highly predictable - but the blower-door number, infrared images, and duct-leakage percentage give you documented evidence to prioritize spending. We conduct Home Energy Audit visits with the same equipment used in utility rebate programs, and you keep all data.
Blower Door Test
Signs you need it
Rooms that never reach temperature, excessive dust, or utility bills 30% above neighbors with similar homes suggest envelope leakage that a blower-door test quantifies precisely in CFM50.
What it costs in Wells Branch
A standalone blower-door test in Wells Branch costs $250-$450, or it’s included at no charge when bundled with a written scope for air sealing or insulation work.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, measure the airflow required to maintain that pressure, and identify leakage locations with smoke pencils and infrared imaging.
Thermal Imaging Inspection
Signs you need it
Cold spots on walls in winter, hot ceiling patches in summer, or a history of ice damming - rare but possible in Wells Branch during Uri-type events - indicate insulation gaps visible only with infrared.
What it costs in Wells Branch
Thermal imaging inspection in Wells Branch runs $150-$300 as a standalone service, or combined with a blower-door test for $350-$550 total.
How we do it
We scan every exterior surface with a FLIR camera during normal heating or cooling operation, mark temperature anomalies on photos, and correlate them with construction details to identify missing or failed insulation.
What Home Energy Audit Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Blower-door test (standalone) | $250 - $450 |
| Thermal imaging inspection | $150 - $300 |
| Full home energy audit (blower door + thermal + duct test) | $400 - $700 |
Does a home energy audit tell me what to fix first in Wells Branch?
Yes - we rank findings by cost-effectiveness and show you the projected savings for each measure. Most Wells Branch homes show air sealing as the highest ROI, followed by attic insulation to R-49. Call (737) 259-8352 to schedule.
How long does a home energy audit take?
Two to three hours for a full audit, including setup, testing, and a walkthrough of findings. You receive the blower-door number, infrared images, and a written priority list before we leave.
