Insulation in Wells Branch, TX
Crawl space encapsulation and vapor barrier work in Wells Branch typically runs $2,800-$5,500 for a full encapsulation with dehumidifier, while smaller vapor-barrier-only jobs start around $1,200. Most Wells Branch homes were built on slab foundations in the 1980s and early 1990s, so true crawl spaces are less common here than in older Austin neighborhoods, but the ones that do exist - often in split-level or walkout designs near the creek beds - suffer from the same clay-soil moisture and summer humidity that plague the broader metro. We treat air sealing as a hard prerequisite before any insulation goes in, and we publish before-and-after blower-door numbers on every job so you can verify the performance change. Call (737) 245-6428 for a written price before any work starts.
Why Wells Branch Homes Are Different
Wells Branch is a master-planned community built almost entirely between roughly 1983 and 1995, one of north Austin’s earliest large subdivisions. That means virtually every home was constructed under 1980s Texas energy codes that required far less attic insulation than today’s R-38+ standard. After 30-40 years of 100°F+ Austin summers baking those attics to 150°F+, the original blown or batt fiberglass has settled, compressed, and been disturbed by decades of HVAC service visits.
The housing stock is strikingly uniform: slab-on-grade single-family tract homes built by a small number of builders in just a few construction waves, mostly 1,400-2,200 sq ft with vaulted or standard 8-ft ceilings and unfinished attics. That tight construction window means insulation deficiencies - thin original batts, unsealed recessed-light cans, and uninsulated HVAC duct boots - are nearly universal across the neighborhood rather than scattered. Because the same floor-plan templates repeat street after street, a technician who air-seals one Wells Branch attic effectively knows the weak-point map for the entire community. Situated in the full-sun suburban fringe, Wells Branch attics hit 150-160°F in July and August, and periodic hard freezes like February 2021 punish the same air-sealing failures in reverse.
Our Main Wells Branch Services
Most Wells Branch homeowners who call us start with attic work or spray foam. Here is what those jobs look like in this neighborhood.
Attic Insulation in Wells Branch
We remove the original 1980s batts or settled blown-in, seal every top plate and penetration with foam and caulk, then install new Owens Corning or Johns Manville insulation to current R-38 or R-49. Because Wells Branch attics run so hot, we pay special attention to duct boot sealing and radiant barrier integration. Every job gets a written price before we start and a Documented Photo Record when we leave. Attic Insulation in Wells Branch
Spray Foam Insulation in Wells Branch
Open-cell and closed-cell spray foam work well in Wells Branch’s vaulted ceilings and bonus-room kneewalls where batt insulation sags and leaves gaps. We air-seal first, then foam, and we provide before-and-after blower-door readings on every applicable job. Our crews source Icynene and Demilec products with no proprietary lock-in. Spray Foam Insulation in Wells Branch
Blown-In Insulation in Wells Branch
Blown-in fiberglass or cellulose is the most common retrofit for Wells Branch’s standard 8-foot-ceiling homes with open attics. We use GreenFiber cellulose or Owens Corning fiberglass, installed over a fully sealed attic floor. The material fills around obstructions better than batts, which matters in these attics where HVAC platforms and recessed-light arrays create complex geometry. Blown-In Insulation in Wells Branch

Crawl Space Encapsulation & Vapor Barrier in Wells Branch
True crawl spaces are uncommon in Wells Branch’s slab-on-grade tract housing, but the split-level and walkout homes near Walnut Creek and its tributaries often have partial crawl spaces that suffer from central Texas clay-soil moisture wicking and summer humidity above 70%. These spaces develop mold on floor joists, musty odors that migrate into living areas, and insulation that falls from saturated bands. Crawl Space Encapsulation & Vapor Barrier work here requires the same sealed-first discipline we apply to attics: we stop the water and air movement before adding any insulation or barrier material.
Crawl Space Vapor Barrier
Signs you need it
You notice musty smells rising from floor registers, see white mineral efflorescence on block walls, or find fiberglass batts hanging wet from joists.
What it costs in Wells Branch
A 6-mil to 20-mil vapor barrier installed over bare earth in a partial crawl space typically runs $1,200-$2,800 depending on square footage and seam-sealing requirements.
How we do it
We remove debris and old fallen insulation, grade the earth, lay overlapping polyethylene sheeting with sealed seams, and extend it 6 inches up foundation walls before mechanical fastening.
Crawl Space Encapsulation
Signs you need it
You have standing water after rains, mold on joists or subfloor, or your hardwood floors are cupping from below-grade moisture migration.
What it costs in Wells Branch
Full encapsulation with sealed vapor barrier, wall insulation, and dehumidifier installation in a Wells Branch crawl space typically ranges $2,800-$5,500.
How we do it
We install a reinforced liner on floors and walls, seal all seams and penetrations with tape and mastic, add closed-cell foam on band joists, and size a dedicated dehumidifier to the space.
What Crawl Space Encapsulation & Vapor Barrier Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Vapor barrier only (6-20 mil) | $1,200 - $2,800 |
| Full encapsulation with dehumidifier | $2,800 - $5,500 |
| Crawl space insulation (band joist foam) | $800 - $1,800 |
Can you encapsulate a partial crawl space under a split-level?
Yes, we treat the accessible portion with vapor barrier and foam, then seal the transition to slab areas with closed-cell foam to stop moisture migration. Call (737) 245-6428 for an exact quote - estimates are free.
Do I need a dehumidifier if I already have a vapor barrier?
In Wells Branch’s humid climate, a vapor barrier alone often leaves relative humidity above 60%; a dehumidifier protects the wood structure long-term. We size the unit to your space and provide written specs.
Radiant Barrier Installation in Wells Branch
Wells Branch attics reach 150-160°F in summer, turning unfinished attic spaces into radiant ovens that force HVAC systems to run continuously. The original 1980s construction in this neighborhood included no radiant barrier, and the dark asphalt shingle roofs common here absorb maximum solar gain. Radiant Barrier Installation reduces radiant heat transfer from roof deck to attic floor by 20-30 degrees, which directly lowers cooling load and extends compressor life in these aging systems.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 p.m., your AC runs 14+ hours daily in July, or your ductwork in the attic feels hot to the touch.
What it costs in Wells Branch
Radiant barrier foil stapled to rafters or laid over attic insulation in a typical 1,600 sq ft Wells Branch attic runs $1,100-$2,400.
How we do it
We install perforated foil across rafter bays 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’re reroofing and want the most effective radiant barrier integration, or your current roof deck shows heat-blistered shingles and shortened shingle life.
What it costs in Wells Branch
Radiant barrier roof deck application during reroofing or as standalone retrofit typically costs $1,800-$3,200 for Wells Branch home sizes.
How we do it
We apply radiant barrier sheathing or foil-faced decking directly to the roof deck structure, creating a permanent radiant block that does not shift or degrade like draped foil.
What Radiant Barrier Installation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic radiant barrier (foil over insulation) | $1,100 - $2,400 |
| Radiant barrier roof deck application | $1,800 - $3,200 |
| Radiant barrier with attic air sealing package | $2,200 - $4,000 |
Will radiant barrier help if my insulation is already thin?
It helps, but we always recommend sealing and insulating to R-38 first; radiant barrier is a complement, not a substitute for adequate insulation depth. We test and document the combined effect.
Does radiant barrier work in winter too?
It reduces heat loss upward in winter, but the primary savings in Wells Branch come from blocking summer roof-deck radiant gain; we factor this into your payback estimate.
Insulation Removal & Replacement in Wells Branch
After 30-40 years, Wells Branch’s original fiberglass batts and early blown-in have compressed, been trampled by HVAC technicians, and often harbor rodent debris or water staining from past roof leaks. The 1980s-era recessed-light cans and bathroom fans created thermal bypasses that deposited dirty air into the insulation layer. Insulation Removal & Replacement in this neighborhood almost always reveals the same pattern: thin, discolored material with visible gaps around penetrations, requiring full removal before proper air sealing and new insulation.
Attic Insulation Removal
Signs you need it
You can see the ceiling drywall through thin or missing insulation, the material is gray or black with dust, or you’ve had roof leaks that soaked the fiberglass.
What it costs in Wells Branch
Removal and disposal of existing attic insulation in a typical Wells Branch home runs $1,000-$2,200 depending on depth and contamination level.
How we do it
We use commercial vacuums with HEPA filtration to extract old material through sealed hoses, bag it for proper disposal, and inspect the deck for mold or structural issues before sealing.
Contaminated Insulation Removal
Signs you need it
You smell urine in the attic, find rodent droppings, or see fungal growth on insulation surfaces after past moisture events.
What it costs in Wells Branch
Contaminated insulation removal with sanitizing and deodorizing in Wells Branch typically ranges $1,800-$3,500 including disposal and surface treatment.
How we do it
We remove all contaminated material, apply EPA-registered sanitizer to exposed wood, install physical barriers where needed, and document the clean deck before new insulation goes in.
What Insulation Removal & Replacement Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Standard attic insulation removal | $1,000 - $2,200 |
| Contaminated insulation removal | $1,800 - $3,500 |
| Removal + replacement with air sealing | $3,500 - $6,500 |
Do I have to leave during insulation removal?
No, our vacuum systems are fully contained, but we recommend avoiding the attic access area during work; we seal the hatch perimeter to prevent dust migration. Call (737) 245-6428 to schedule.
How long does removal and replacement take?
Most Wells Branch homes complete in one to two days: removal and sealing on day one, new insulation installation and blower-door verification on day two.
Attic Air Sealing in Wells Branch
Wells Branch’s uniform 1980s construction means the same air-leak patterns repeat across the neighborhood: unsealed top plates where partition walls meet the attic, recessed-light cans without airtight housings, and pull-down attic stairs with no weatherstripping. After decades of thermal cycling, the original caulk and foam have hardened and cracked. Attic Air Sealing is the single highest-ROI improvement for these homes, and we never install new insulation over an unsealed attic floor - it’s sealed first, then insulated, in that order.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts from ceiling fixtures, see dust streaks around register boots, or your blower-door test shows excessive air leakage despite average insulation depth.
What it costs in Wells Branch
Comprehensive top plate and penetration sealing in a typical Wells Branch attic runs $800-$1,800 as a standalone service, or bundled with insulation work.
How we do it
We foam-seal every top plate joint, wire penetration, and pipe chase with one-part or two-part polyurethane foam, then verify with blower-door testing to confirm reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights flicker in wind, conditioned air blows into the attic around duct connections, or you see insulation displaced by air movement around boots.
What it costs in Wells Branch
Sealing recessed-light housings and HVAC duct boots in a standard Wells Branch home typically costs $600-$1,400 depending on fixture count and accessibility.
How we do it
We install fire-rated covers over non-IC cans, seal with latex foam, then mastic-seal duct boots and support connections before reinsulating around them.
What Attic Air Sealing Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Top plate and penetration sealing | $800 - $1,800 |
| Can light and duct boot sealing | $600 - $1,400 |
| Full attic air sealing package | $1,400 - $3,000 |
Can you air-seal without adding insulation?
Yes, we perform standalone air sealing with blower-door verification, though we typically recommend pairing it with insulation to R-38 for full performance. Written price before any work starts.
How much does air sealing reduce my bills?
Wells Branch homes from this era typically see 15-25% reduction in heating and cooling load after comprehensive attic air sealing; we document the before-and-after CFM50 reading so you can verify.
Wall Insulation in Wells Branch
Wells Branch’s 1980s tract homes were built with 2×4 exterior walls and minimal or no cavity insulation in some early construction phases, leaving exterior walls cold in winter and hot to the touch in summer. The uniform floor plans mean the same uninsulated garage-adjacent walls and west-facing master bedrooms repeat across dozens of homes. Wall Insulation retrofit here requires careful technique to avoid moisture trapping in these older wall assemblies that were not designed for modern insulation densities.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot or cold to the touch, you have high utility bills despite attic work, or thermography shows empty cavities in finished walls.
What it costs in Wells Branch
Injection foam insulation for exterior walls in a typical 1,600 sq ft Wells Branch home runs $3,500-$6,500 depending on cavity count and access method.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud-bay intervals, inject slow-rise foam that fills without bowing, then patch and match finish.
Drill & Fill Wall Insulation
Signs you need it
You have empty wall cavities confirmed by outlet removal, or your home was built in the early 1980s before wall insulation was consistently required in Texas.
What it costs in Wells Branch
Drill-and-fill with dense-pack cellulose or fiberglass in Wells Branch homes typically costs $2,800-$5,200 for full exterior wall coverage.
How we do it
We remove a course of siding or drill interior drywall, blow cellulose or fiberglass to calculated density with tube-fill verification, then restore all surfaces.
What Wall Insulation Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Injection foam wall insulation | $3,500 - $6,500 |
| Drill-and-fill dense pack | $2,800 - $5,200 |
| Garage wall and bonus room insulation | $1,200 - $2,800 |
Will injection foam damage my walls?
We use slow-rise formulations and controlled pressure to prevent bowing; in 9,000+ jobs since 2016, we have not had a structural failure. Call (737) 245-6428 for specifics on your wall construction.
Can you insulate walls without removing drywall?
Yes, exterior access through siding or minimal interior patching is standard; we match texture and paint where interior access is required.
Attic Cleaning & Rodent Proofing in Wells Branch
Wells Branch’s mature tree canopy and established neighborhoods support active squirrel, rat, and mouse populations that exploit construction gaps in 1980s-era homes. The original attic vents, unsealed eave returns, and deteriorating fascia create entry highways, while compressed insulation provides nesting material. Attic Cleaning & Rodent Proofing here follows a documented protocol: remove contamination, sanitize, seal every entry point, then restore insulation performance.
Attic Cleanout & Sanitizing
Signs you need it
You hear scratching at night, find droppings in the attic, or smell ammonia-like odors that worsen in summer heat.
What it costs in Wells Branch
Attic cleanout with HEPA vacuuming, sanitizing, and deodorizing in a typical Wells Branch attic runs $1,200-$2,800.
How we do it
We remove all contaminated insulation and debris, apply enzymatic sanitizer to wood surfaces, and run ozone or hydroxyl treatment before installing new materials.
Rodent Proofing & Exclusion
Signs you need it
You have recurring rodent activity despite trapping, or you can see daylight through eave gaps, vent screens, or around plumbing penetrations.
What it costs in Wells Branch
Comprehensive rodent proofing with exclusion hardware cloth, foam, and metal flashing in Wells Branch typically costs $800-$2,000.
How we do it
We install 1/4-inch hardware cloth over vents, seal eave and soffit gaps with copper mesh and foam, and use metal flashing where rodents have chewed through softer materials.
What Attic Cleaning & Rodent Proofing Costs in Wells Branch
| Item | Typical range in Wells Branch |
|---|---|
| Attic cleanout and sanitizing | $1,200 - $2,800 |
| Rodent proofing and exclusion | $800 - $2,000 |
| Full restoration (cleanout + proofing + insulation) | $3,500 - $7,000 |
How do you keep rodents from coming back?
We seal every entry larger than 1/4 inch with rodent-resistant materials and provide a written exclusion map; our 365-Day Done Right Promise covers re-entry if our seal fails. Call (737) 245-6428.
Is rodent-damaged insulation safe to leave?
No, rodent waste can harbor hantavirus and other pathogens; we remove it completely and sanitize before any new insulation contacts the deck.

What Wells Branch Customers Say
"They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N."Turned up on time, protected the hallway, and the written scope matched what was actually done."
- Bruno S."Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E.
