Insulation in Wells Branch, TX
Crawl space encapsulation and vapor barrier installation in Wells Branch typically runs $3,200-$6,800 for most homes, with jobs completed in one to two days. Because Wells Branch’s 1980s-era homes were built on slab foundations with minimal attention to ground moisture control, homes with crawl spaces - often additions or specific tracts near Walnut Creek - face humidity issues that standard insulation alone cannot fix. We’re Envelope Insulation Co., and we treat air sealing as a prerequisite, not an upsell. Every job starts with a written price and ends with a Documented Photo Record. Call (737) 259-7528 for a free estimate.
Why Wells Branch Homes Are Different
Wells Branch is a master-planned community built almost entirely in a compressed 1980s development window, meaning the residential stock is now 35-40 years old with its original builder-grade insulation installed to the minimal Texas energy codes of that era - often R-19 or less in attics. With Austin-area summers pushing attic temperatures past 140°F, virtually every home in the community is simultaneously overdue for an insulation upgrade, creating an unusually concentrated and uniform retrofit market.
The housing stock is predominantly single-story and two-story brick-veneer tract homes on slab foundations, with aging fiberglass batts and blown-in insulation that has been settling and degrading under extreme heat for three to four decades. Winter Storm Uri in 2021 exposed how poorly these homes perform on the cold side. A pattern our technicians encounter constantly: 1980s builders routed HVAC flex ductwork through unconditioned attics, and after 35-plus summers, the foil-faced duct insulation cracks and separates at joints - meaning conditioned air escapes into 140°F space before reaching the living area.
Our Main Wells Branch Services
Most Wells Branch homeowners who call us start with attic work or whole-home spray foam. Here is how we approach the two most common requests.
Attic Insulation in Wells Branch
Attic insulation in Wells Branch almost always means removing degraded R-19 fiberglass batts and upgrading to R-38 or R-49 blown-in cellulose or fiberglass, because the original 1980s installation has compressed well below its labeled value. We air seal top plates, can lights, and duct boots before adding material - never over an unsealed floor. Attic Insulation in Wells Branch covers our full process, pricing, and what the blower-door documentation looks like.

Spray Foam Insulation in Wells Branch
Spray foam insulation in Wells Branch works best for open attics, bonus rooms over garages, and the rare crawl space or rim joist where air sealing and insulation must happen simultaneously. We specify open-cell foam for most attic applications and closed-cell for moisture-prone areas, sourcing from Icynene and Demilec with no proprietary lock-in. Spray Foam Insulation in Wells Branch details our application standards and written-price process.

Blown-In Insulation in Wells Branch
Blown-in insulation in Wells Branch is the most cost-effective retrofit for the typical 1,400-2,200 square foot home in the area, especially when the existing batts are too degraded to salvage. We use Owens Corning AttiCat and GreenFiber cellulose systems, installed to density after complete air sealing. Blown-In Insulation in Wells Branch explains our depth targets, coverage calculators, and how we document before-and-after blower-door readings.

Crawl Space Encapsulation & Vapor Barrier in Wells Branch

Wells Branch’s 1980s construction boom left a subset of homes, particularly those near Walnut Creek and in certain infill tracts, with vented crawl spaces that were never properly sealed against Central Texas humidity. Ground moisture rises through these spaces year-round, but summer conditions - when the crawl space becomes a convection oven driving humid air upward - make the problem acute, accelerating floor joist rot and creating conditions for mold that standard attic ventilation cannot address. Crawl Space Encapsulation & Vapor Barrier is our systematic response.
Crawl Space Vapor Barrier
Signs you need it
Condensation on ductwork in the crawl space, musty odors rising through floor registers, or soft spots in subflooring near kitchen and bath plumbing.
What it costs in Wells Branch
Most vapor barrier installations in Wells Branch run $1,800-$3,400 for a standard 1,200 square foot crawl space, with 10-mil reinforced polyethylene and sealed seams.
How we do it
We remove debris and grade the soil, lay overlapping sheets of reinforced polyethylene, seal all seams with vapor-proof tape, and extend the barrier six inches up pier walls before fastening and sealing.
Crawl Space Encapsulation
Signs you need it
Standing water after rain, visible mold on joists or insulation, or HVAC equipment in the crawl space that fails prematurely from corrosion.
What it costs in Wells Branch
Full encapsulation in Wells Branch typically ranges from $4,200-$8,500 depending on crawl space height, existing damage, and whether a dehumidifier is required.
How we do it
We install a complete vapor barrier across floor and walls, seal foundation vents, insulate rim joists with closed-cell spray foam, and add a mechanical dehumidifier with a dedicated drain line.
What Crawl Space Encapsulation & Vapor Barrier Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Vapor barrier (10-mil, floor only) | $1,800 - $3,400 |
| Full encapsulation with dehumidifier | $4,200 - $8,500 |
| Rim joist spray foam (closed-cell) | $1,200 - $2,600 |
How long does crawl space encapsulation take in Wells Branch?
Most Wells Branch crawl space encapsulation jobs are completed in one to two days, with larger or more damaged spaces requiring up to three. We provide a written schedule with the price before work starts.
Will encapsulation fix my musty smell?
Yes, in nearly every Wells Branch case we have handled, sealing the ground moisture source and adding mechanical dehumidification eliminates musty odors within 48 hours of system startup.
Radiant Barrier Installation in Wells Branch

Wells Branch attics regularly reach 140-150°F in July and August, and the original 1980s insulation in these homes was never designed to block radiant heat transfer - only conductive heat flow through the material itself. A radiant barrier reflects infrared radiation away from the living space, reducing attic surface temperatures by 20-35°F and cutting cooling load on aging HVAC systems that are already stressed by cracked ductwork. Radiant Barrier Installation is one of the highest-ROI retrofits we offer in this market.
Attic Radiant Barrier
Signs you need it
Second-story rooms that stay hot despite lower thermostat settings, or an HVAC system that runs continuously from noon to 8 p.m. in summer.
What it costs in Wells Branch
Attic radiant barrier installation in Wells Branch typically runs $1,400-$2,800 for a standard tract home, depending on attic complexity and accessibility.
How we do it
We staple perforated radiant barrier foil across the bottom of rafters, maintaining ventilation channels, or lay it over existing attic insulation with proper air gaps.
Radiant Barrier Roof Deck
Signs you need it
New roof installation planned, or existing roof deck visible from inside the attic due to missing decking or during a re-roof.
What it costs in Wells Branch
Roof-deck radiant barrier application in Wells Branch ranges $2,200-$4,500, typically done during re-roofing for optimal adhesion and coverage.
How we do it
We apply radiant barrier paint or foil-backed sheathing directly to the roof deck, creating a permanent reflective surface that does not degrade from dust accumulation.
What Radiant Barrier Installation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic radiant barrier (foil, stapled) | $1,400 - $2,800 |
| Radiant barrier roof deck application | $2,200 - $4,500 |
| Radiant barrier with attic air sealing | $2,600 - $5,200 |
Does radiant barrier work with my old insulation?
Yes, radiant barrier complements existing insulation by addressing the heat transfer mechanism the old material cannot block, and we often install both during the same visit.
How much will my cooling bill drop?
Wells Branch homeowners typically see summer cooling reductions of 8-15% after radiant barrier installation, with greater savings when combined with duct sealing and attic air sealing.
Insulation Removal & Replacement in Wells Branch

After 35-40 years in Wells Branch’s extreme attic heat, original fiberglass batts have compressed, torn, and often been contaminated by rodent activity or water staining from roof leaks that went unaddressed. Removing this degraded material is not optional if you want new insulation to perform to specification - blown-in cellulose or fiberglass laid over compacted, dirty batts creates thermal bridges and traps moisture against the ceiling drywall. Insulation Removal & Replacement is how we reset the attic to a clean, sealed, properly insulated state.
Attic Insulation Removal
Signs you need it
Insulation visibly flattened below joist tops, discolored from roof leaks, or containing rodent droppings and nesting material.
What it costs in Wells Branch
Attic insulation removal in Wells Branch runs $1.20-$2.40 per square foot, or roughly $1,700-$4,200 for a typical 1,400-2,200 square foot home.
How we do it
We use commercial vacuums with HEPA filtration and 4-mil bagging, removing all material down to the ceiling drywall before inspecting and sealing air leaks.
Contaminated Insulation Removal
Signs you need it
Strong ammonia odor from rodent urine, visible mold on insulation surfaces, or evidence of raccoon or squirrel habitation in the attic.
What it costs in Wells Branch
Contaminated removal in Wells Branch ranges $2.50-$4.80 per square foot, including PPE, HEPA containment, and proper disposal per Texas regulations.
How we do it
We establish negative air pressure, remove contaminated material in sealed bags, apply enzyme-based sanitizing agent to affected surfaces, and verify with ATP testing before reinstalling insulation.
What Insulation Removal & Replacement Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Standard attic insulation removal | $1,700 - $4,200 |
| Contaminated insulation removal | $3,500 - $10,500 |
| Removal + replacement with R-38 blown-in | $3,800 - $7,400 |
Do I have to leave during removal?
No, our containment and ventilation protocols allow you to remain in the home, though we recommend avoiding the immediate work zone during active vacuuming.
Can you remove insulation with asbestos?
We do not handle asbestos-containing materials; if we suspect vermiculite or asbestos-laden insulation, we stop work and refer you to a licensed abatement contractor for testing and removal.
Attic Air Sealing in Wells Branch

The 1980s builders in Wells Branch paid minimal attention to the building envelope as a continuous air barrier - top plates were left unsealed, can lights were installed without airtight housings, and drywall gaps at duct boots were common. After four decades of thermal cycling, these leaks have often widened, and the cracked duct insulation our technicians regularly find means conditioned air is being pumped directly into 140°F attic space. Attic Air Sealing is the prerequisite step we never skip; we will not blow insulation over an unsealed attic floor.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks on insulation around wall top plates, or rooms that are significantly colder in winter despite adequate insulation depth.
What it costs in Wells Branch
Top plate and penetration sealing in Wells Branch typically runs $800-$1,800 for a standard home, depending on wall count and wiring density.
How we do it
We seal all top plate gaps with acoustical sealant or expanding foam, address plumbing and electrical penetrations with fire-rated foam, and verify with blower-door testing before and after.
Can Light & Duct Boot Sealing
Signs you need it
Air leaking around can light trim in finished ceilings, or flex duct connections that have pulled loose from ceiling boots.
What it costs in Wells Branch
Can light and duct boot sealing in Wells Branch ranges $600-$1,400, with IC-rated airtight housings for non-IC fixtures adding $45-$85 per light.
How we do it
We install pre-formed airtight covers or replace non-IC housings, seal duct boots with mastic and mesh, and support flex duct to prevent future separation.
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 | $600 - $1,400 |
| Full attic air sealing package | $1,400 - $3,200 |
How much does air sealing improve efficiency?
Our Wells Branch jobs typically show blower-door reductions of 25-40%, meaning the home loses that much less conditioned air; the before-and-after numbers are included in your documentation.
Can you air seal without adding insulation?
Yes, we perform air sealing as a standalone service, though we always recommend verifying adequate insulation depth afterward since the two systems work together.
Wall Insulation in Wells Branch

Wells Branch’s 1980s homes were built with 2×4 exterior walls and minimal cavity insulation, often fiberglass batts that have settled or been compromised by wiring and plumbing penetrations over four decades. Winter Storm Uri proved how poorly these walls perform when temperatures drop below freezing for extended periods - interior surface temperatures in exterior walls fell low enough to create condensation and mold risk in many homes. Wall Insulation retrofits address this without requiring full gut renovation.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that are cold to the touch in winter, or rooms with two exterior walls that are consistently 5-10°F cooler than interior rooms.
What it costs in Wells Branch
Injection foam wall insulation in Wells Branch runs $3.50-$6.50 per square foot of wall area, or roughly $4,200-$8,800 for a typical 1,800 square foot home.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud intervals, inject slow-rise foam that fills cavities without bowing walls, and patch with matching materials.
Drill & Fill Wall Insulation
Signs you need it
Empty wall cavities confirmed by thermal imaging, or walls with settled fiberglass that no longer reaches the top plate.
What it costs in Wells Branch
Drill and fill with dense-pack cellulose in Wells Branch ranges $2.80-$5.20 per square foot, with interior access preferred for homes with brittle or hard-to-match exterior siding.
How we do it
We remove a strip of interior drywall near the ceiling, dense-pack cellulose to 3.5 pounds per cubic foot, then patch and texture-match the access holes.
What Wall Insulation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Injection foam (exterior walls) | $4,200 - $8,800 |
| Dense-pack cellulose drill & fill | $3,400 - $7,200 |
| Interior wall soundproofing | $2,200 - $4,800 |
Will injection foam damage my walls?
No, we use slow-rise formulations specifically designed for existing wall cavities, and our Wells Branch crews verify no bowing or drywall stress before patching.
Do you need to remove drywall?
Exterior injection foam requires only small drilled holes; interior drill-and-fill cellulose requires limited drywall removal that we patch as part of the scope.
Attic Cleaning & Rodent Proofing in Wells Branch

The mature trees and greenbelts that make Wells Branch attractive also support active squirrel, raccoon, and roof rat populations that exploit aging 1980s construction - rotted fascia boards, unscreened vents, and gaps where additions meet original structure. Once inside, rodents compress and contaminate insulation, creating health hazards and eliminating thermal performance. Attic Cleaning & Rodent Proofing restores the space to a clean, sealed condition before any new insulation goes in.
Attic Cleanout & Sanitizing
Signs you need it
Visible rodent droppings on insulation or joists, strong ammonia odor when entering the attic, or insulation stained with urine.
What it costs in Wells Branch
Attic cleanout and sanitizing in Wells Branch runs $1,800-$3,600 for a typical home, with heavy contamination or large attic spaces at the higher end.
How we do it
We remove all contaminated insulation and debris, apply enzyme-based sanitizer to kill bacteria and neutralize odors, and provide photographic documentation of the cleaned space.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in walls or ceiling, visible entry gaps at roof intersections, or recurring rodent activity after previous trapping efforts.
What it costs in Wells Branch
Rodent proofing and exclusion in Wells Branch typically ranges $1,200-$2,800, with one-way exit devices and comprehensive sealing of all entry points larger than 1/4 inch.
How we do it
We install one-way exit devices at active entry points, seal all gaps with rodent-proof materials including steel mesh and concrete patch, and provide a written warranty against re-entry.
What Attic Cleaning & Rodent Proofing Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic cleanout & sanitizing | $1,800 - $3,600 |
| Rodent proofing & exclusion | $1,200 - $2,800 |
| Full restoration (cleanout + proofing + insulation) | $4,800 - $9,200 |
How do I know if rodents are in my attic?
Listen for scratching at dawn and dusk, check for droppings near attic access points, and look for gnaw marks on fascia boards or vent screens - all common in Wells Branch’s mature-tree corridors.
Will proofing keep them out permanently?
Our exclusion work carries a written warranty; we seal every entry point 1/4 inch or larger with materials rodents cannot chew through, and we document each sealed location with photos.
Home Energy Audit in Wells Branch

A home energy audit in Wells Branch reveals exactly how a 1980s-era building envelope is failing under current climate conditions - not guesswork, but measured data on air leakage, thermal bypasses, and duct losses. With Austin-area cooling loads among the highest in Texas and Winter Storm Uri still fresh in memory, homeowners need documented evidence of where conditioned air escapes and which upgrades will deliver measurable return. Home Energy Audit provides that evidence in a written report with prioritized recommendations.
Blower Door Test
Signs you need it
High utility bills with no obvious cause, or rooms that never reach set temperature despite adequate HVAC capacity.
What it costs in Wells Branch
A standalone blower-door test in Wells Branch runs $350-$550, or is included at no additional charge when bundled with our air sealing or insulation services.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, and measure CFM50 - the cubic feet per minute of air leakage at standard pressure.
Thermal Imaging Inspection
Signs you need it
Visible temperature variations on walls or ceilings, or suspicion of missing insulation in finished spaces where removal is not practical.
What it costs in Wells Branch
Thermal imaging inspection in Wells Branch ranges $275-$450 as a standalone service, or combined with blower-door testing for $500-$750 total.
How we do it
We use FLIR infrared cameras during blower-door depressurization to visualize air leakage paths and insulation gaps, capturing images for your documented record.
What Home Energy Audit Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Blower-door test | $350 - $550 |
| Thermal imaging inspection | $275 - $450 |
| Full audit (blower door + thermal + duct test + report) | $650 - $1,100 |
How long does a home energy audit take?
Most Wells Branch audits require 2.5-4 hours on site, with the written report and prioritized recommendations delivered within 48 hours.
Will the audit tell me what to fix first?
Yes, every Wells Branch audit report ranks recommendations by cost-effectiveness and comfort impact, with estimated savings and payback periods for each measure.
