Insulation in Shady Hollow, TX
Crawl space encapsulation and vapor barrier work in Shady Hollow typically runs between $2,800 and $6,500 for the 1,800-3,000 sq ft homes that dominate this south Travis County community, with most jobs completed in one to two days. Because Shady Hollow was built out predominantly in the 1980s and 1990s under pre-modern energy codes, the crawl spaces we encounter rarely have adequate ground moisture control or perimeter sealing, and the humid subtropical climate here means year-round vapor drive from the soil. Every job starts with a written price and ends with a documented record. Call (737) 337-8049 for a free estimate.
Why Shady Hollow Homes Are Different
Shady Hollow sits in an unincorporated pocket of south Travis County, which means the 1980s and 1990s tract homes here were built without the permit and energy-code inspections that Austin-proper remodels now trigger. The result is a dense concentration of homes carrying 30-40-year-old fiberglass batt or blown insulation that has settled well below its original R-value, with attic assemblies typically at R-19 to R-22 instead of the R-38 to R-60 now recommended for Central Texas.
The July and August heat pushes unconditioned attics to 150-160°F, and the February 2021 freeze exposed how poorly this era of construction handles cold infiltration. A recurring pattern our technicians find in Shady Hollow homes: pull-down attic stair openings that were never insulated or air-sealed at the rough framing stage, creating a direct chimney between the attic and living space. The terrain is typical Hill Country transition zone - clay soils that shift, crawl spaces that breathe moisture, and oak canopy that drops debris into gutters and soffit vents.
Our Main Shady Hollow Services
Shady Hollow homeowners call us most often for attic work and spray foam - here is what each involves in this market.
Attic Insulation in Shady Hollow
Most Shady Hollow attics we enter still contain the original blown fiberglass from the build date, now compressed and often displaced by decades of tradespeople walking the joists. We remove or overlay depending on condition, air-seal the floor plane first, then install to current R-38 or higher using Owens Corning or Johns Manville products. Every attic job includes a documented photo record and, where applicable, before-and-after blower-door numbers. Attic Insulation in Shady Hollow covers our full process and pricing.
Spray Foam Insulation in Shady Hollow
Spray foam is the fix we recommend for Shady Hollow’s rim joists, cathedral ceilings, and the unsealed knee walls common in two-story brick-veneer homes from this building era. We use open-cell and closed-cell products from Icynene and Demilec, selected by application, never by proprietary lock-in. The 2021 freeze drove demand for rim-joist sealing here, and we’re still catching up homes that lost pipes to cold infiltration. Spray Foam Insulation in Shady Hollow has material specs and cost ranges.
Blown-In Insulation in Shady Hollow
Blown-in fiberglass or cellulose is the most common retrofit for Shady Hollow’s open-truss attics, especially when the existing material is salvageable but thin. We blow GreenFiber cellulose or Owens Corning fiberglass over a fully sealed attic floor, never over unsealed top plates or can-light penetrations. The work takes four to six hours for a typical 2,200 sq ft home, and you receive the photo record and written scope same-day. Blown-In Insulation in Shady Hollow details density targets and coverage.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Shady Hollow
Shady Hollow’s 1980s and 1990s homes were built with vented crawl spaces that allow Central Texas humidity to migrate freely through the floor assembly, and the clay soils here wick moisture year-round. Crawl Space Encapsulation & Vapor Barrier is our primary service in this community because encapsulation stops that vapor drive, protects floor joists from rot, and eliminates the musty air that rises into living spaces through plumbing and electrical penetrations. Most Shady Hollow crawl spaces we encapsulate measure 1,200-2,400 sq ft of ground plane and perimeter wall.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or soft spots in the subfloor above the kitchen or bathrooms.
What it costs in Shady Hollow
A 6-mil to 20-mil vapor barrier installed over the ground plane in a typical Shady Hollow crawl space runs $1.20-$2.80 per square foot, so most jobs fall between $1,800 and $4,200.
How we do it
We remove debris, grade the soil for drainage, seam-seal the polyethylene sheeting at all overlaps, and mechanically fasten it to perimeter walls six inches above outside grade.
Crawl Space Encapsulation
Signs you need it
You smell mustiness on the first floor in humid months, your hardwood floors cup at the edges, or your HVAC ducts in the crawl space show corrosion on the exterior insulation.
What it costs in Shady Hollow
Full encapsulation with sealed vapor barrier, perimeter wall insulation, and conditioned-air supply typically ranges from $4,500 to $9,500 for Shady Hollow’s 1,800-3,000 sq ft homes.
How we do it
We seal all vents, install rigid foam or closed-cell spray foam on perimeter walls, lay a sealed ground vapor barrier, and add a dehumidistat-controlled exhaust or supply duct depending on the existing HVAC configuration.
What Crawl Space Encapsulation & Vapor Barrier Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Vapor barrier (ground plane only) | $1,800 - $4,200 |
| Full encapsulation with wall insulation | $4,500 - $9,500 |
| Dehumidifier installation | $1,200 - $2,800 |
How long does crawl space encapsulation take in Shady Hollow?
Most Shady Hollow jobs finish in one to two days, with larger perimeter-wall foam jobs extending to three. We deliver the written scope and warranty before the crew starts, and you receive the documented photo record and any blower-door or moisture-meter readings before we leave. Call (737) 337-8049 to schedule a free estimate.
Will encapsulation fix my musty smell?
Yes, when the source is ground moisture vapor - the most common cause in Shady Hollow’s vented crawl spaces. If the odor persists after encapsulation and dehumidification, we investigate secondary sources like plumbing leaks or exterior drainage failures, documented in the photo record. Call (737) 337-8049 for an assessment.
Radiant Barrier Installation in Shady Hollow
Radiant barrier installation in Shady Hollow addresses the single most brutal condition these 1980s and 1990s homes face: attic temperatures of 150-160°F from May through September, radiating heat through the ceiling plane and forcing air conditioners to run continuously. Radiant Barrier Installation reflects that radiant heat back toward the roof deck rather than letting it load the insulation and drywall below, and in Shady Hollow’s shallow rafter cavities, it is often the only practical retrofit that doesn’t require raising the roofline or compressing insulation.
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 ceiling drywall is warm to the touch on a sunny afternoon.
What it costs in Shady Hollow
Radiant barrier foil stapled to rafter bottoms in a typical Shady Hollow attic runs $1.10-$2.40 per square foot of attic footprint, with most jobs between $2,200 and $5,800.
How we do it
We install perforated double-sided aluminum foil across the underside of rafters, maintaining a minimum 3/4-inch air gap above and vent path to ridge or gable vents, then verify with an infrared thermometer.
Radiant Barrier Roof Deck
Signs you need it
You’re replacing your roof and want the radiant barrier integrated at the deck level rather than retrofitting from inside the attic later.
What it costs in Shady Hollow
Radiant barrier roof-deck installation during re-roofing, using foil-faced OSB or laminated decking, adds $0.80-$1.90 per square foot to the roofing project, typically $1,600-$4,500 for Shady Hollow home sizes.
How we do it
We coordinate with your roofing contractor to install foil-faced structural panels or radiant barrier sheathing at the deck, taped at seams, with documented photos of the deck before shingles go on.
What Radiant Barrier Installation Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Attic radiant barrier (rafter staple-up) | $2,200 - $5,800 |
| Radiant barrier roof deck (during re-roof) | $1,600 - $4,500 |
| Radiant barrier with attic ventilation upgrade | $3,200 - $7,400 |
Does radiant barrier work with existing insulation?
Yes, and it works best when the attic floor is already air-sealed and insulated to R-38 or higher - we verify existing conditions before quoting and include any needed air sealing in the written scope. Call (737) 337-8049 for a free estimate.
Will radiant barrier help my upstairs bedrooms?
Yes, that is the primary complaint we solve in Shady Hollow’s two-story homes, where the thermal stack effect plus radiant ceiling load makes upstairs rooms 8-12°F warmer than downstairs. The reduction in radiant heat transfer lets the existing HVAC meet setpoint instead of fighting attic gain. Call (737) 337-8049 to discuss your floor plan.
Insulation Removal & Replacement in Shady Hollow
Insulation Removal & Replacement is not a cosmetic service here; it is a performance recovery job, because R-19 that has compressed to R-12 or harbors rodent waste is doing active harm to indoor air quality and energy bills.
Attic Insulation Removal
Signs you need it
Your attic insulation is flat and foot-packed near the access hatch, you find rodent droppings or nesting material, or the fiberglass has dark staining from dust filtration at air leaks.
What it costs in Shady Hollow
Removal of existing attic insulation in a typical Shady Hollow home runs $1.40-$3.20 per square foot, or $2,500-$6,800 for the 1,800-3,000 sq ft range, before replacement.
How we do it
We contain the attic access with negative-air HEPA filtration, remove material by vacuum or bag, dispose per Travis County regulations, and photograph the bare deck before any new work begins.
Contaminated Insulation Removal
Signs you need it
You smell ammonia or musk in the hallway near the attic hatch, or you’ve had rodent activity confirmed by a pest control operator who recommended insulation replacement after exclusion.
What it costs in Shady Hollow
Contaminated removal with full PPE, HEPA containment, and antimicrobial treatment of the attic deck runs $2.20-$4.80 per square foot, typically $4,000-$10,500 in this market.
How we do it
We suit in respirators and coveralls, establish negative pressure, remove contaminated material, apply enzyme or antimicrobial treatment to the deck and joists, and hold for your pest control clearance before installing new insulation.
What Insulation Removal & Replacement Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Standard attic insulation removal | $2,500 - $6,800 |
| Contaminated insulation removal | $4,000 - $10,500 |
| Removal + replacement to R-38 | $5,500 - $12,400 |
Do I need to leave during insulation removal?
No, our containment and negative-air setup keeps the living space isolated, though we recommend sensitive individuals spend the day elsewhere as a precaution. We deliver the photo record showing the sealed containment and clean deck before replacement begins. Call (737) 337-8049 to schedule.
How do I know if my insulation is contaminated?
Rodent droppings, urine staining, or compressed paths through the material are visible evidence; musty or ammonia odors from the attic hatch are olfactory confirmation. We inspect and photograph during our free estimate, and we do not quote replacement without documenting why removal is necessary. Call (737) 337-8049.
Attic Air Sealing in Shady Hollow
Attic air sealing in Shady Hollow is the foundational step we refuse to skip, because blowing new insulation over an unsealed attic floor is sealing in the problem, not solving it. Attic Air Sealing targets the top plates, can lights, duct boots, and pull-down stair openings that were never sealed during original construction in this community’s 1980s and 1990s homes - and the blower-door test we run before and after shows the exact CFM50 reduction you paid for.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at interior wall outlets in winter, your attic insulation has dark streaks at the wall top plates, or your blower-door test shows excessive leakage at the ceiling plane.
What it costs in Shady Hollow
Top plate and penetration sealing in a typical Shady Hollow attic runs $1.80-$3.60 per linear foot of wall top plate, with most homes falling between $2,400 and $5,200 for full attic floor sealing.
How we do it
We access the attic floor, remove existing insulation in work zones, seal all top plates and wire/plumbing penetrations with fire-rated caulk and spray foam, then replace insulation and photograph every sealed location.
Attic Hatch Sealing
Signs you need it
Your pull-down stairs wobble in the frame, you see daylight around the perimeter when the hatch is closed, or an infrared camera shows a hot rectangle on the ceiling in summer.
What it costs in Shady Hollow
A site-built or pre-fabricated insulated attic hatch with compression weatherstripping and latch hardware runs $380-$920 installed in Shady Hollow homes.
How we do it
We build a dam around the stair frame, insulate the back of the stair panel with rigid foam, install bulb or compression weatherstripping on the frame, and add mechanical latches to maintain seal pressure.
What Attic Air Sealing Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Full attic floor air sealing (top plates, penetrations) | $2,400 - $5,200 |
| Attic hatch sealing and insulation | $380 - $920 |
| Attic air sealing with blower-door verification | $2,800 - $5,800 |
Can you air-seal without removing all my insulation?
Yes, we remove only what blocks access to the top plates and penetrations, then replace it; the photo record shows before, during, and after each zone. For blown-in that is deep and uniform, we may recommend removal and re-blow for full access, quoted separately. Call (737) 337-8049 for an exact scope.
What does a blower-door test tell me?
A blower-door test is a pressurization reading that shows, in one number, how much air your building envelope is losing; we measure CFM50 before sealing and after, and you receive both figures in writing. In Shady Hollow’s 1980s homes, we typically see 3,500-5,500 CFM50 before and 2,000-3,200 after comprehensive attic sealing. Call (737) 337-8049 to schedule.
Wall Insulation in Shady Hollow
Wall insulation in Shady Hollow addresses the hollow 2×4 or 2×6 exterior walls common in 1980s and 1990s tract construction, which were often insulated with thin fiberglass batts that have settled or were never fully filled at the top and bottom of stud bays. Wall Insulation retrofit is the most invasive insulation work we do, but in Shady Hollow it delivers measurable results for rooms that overheat on west walls or feel cold in January despite adequate attic insulation.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch inside on summer afternoons, you can hear outdoor conversation through closed windows, or an infrared scan shows stud-pattern cold spots in winter.
What it costs in Shady Hollow
Injection foam into enclosed wall cavities runs $3.20-$6.80 per square foot of wall area, with typical Shady Hollow homes ranging from $4,800 to $12,000 for full exterior wall treatment.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud-bay centers, inject slow-rise foam until resistance indicates full fill, plug and finish the holes, and verify with thermal imaging.
Drill & Fill Wall Insulation
Signs you need it
You have confirmed empty stud bays during a renovation, your home was built with no exterior wall insulation, or the existing batt has fallen to the bottom of the cavity.
What it costs in Shady Hollow
Drill and fill with cellulose or fiberglass in empty 2×4 walls runs $2.40-$5.20 per square foot, typically $3,600-$9,200 for Shady Hollow’s exterior wall area.
How we do it
We drill access holes at top and bottom of each bay, blow cellulose or fiberglass to verified density, seal holes with matching plugs, and provide the documented photo record of fill verification.
What Wall Insulation Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Injection foam (enclosed cavities) | $4,800 - $12,000 |
| Drill & fill cellulose/fiberglass (empty cavities) | $3,600 - $9,200 |
| Interior wall soundproofing with Rockwool | $2,800 - $7,400 |
Will injection foam damage my walls?
The slow-rise formulations we use exert minimal pressure on drywall or plaster, and we drill through siding or interior surfaces that can be patched invisibly. We photograph every hole location before repair and include touch-up in the written scope. Call (737) 337-8049 for a free assessment.
Can you insulate walls without tearing off siding?
Yes, interior-side drill and fill is standard for homes with brick or hard-to-match siding; exterior access is preferred for vinyl or fiber-cement that patches cleanly. We recommend the approach that preserves your finish during the free estimate walkthrough. Call (737) 337-8049.
Attic Cleaning & Rodent Proofing in Shady Hollow
Attic cleaning and rodent proofing in Shady Hollow is driven by the mature oak canopy that surrounds these 1980s and 1990s homes, providing bridge access for roof rats and squirrels that exploit unsealed soffit vents, gable vent screens, and the gaps at roof-to-wall intersections common in this era’s construction. Attic Cleaning & Rodent Proofing is not pest control - it is the structural and sanitary recovery work that follows exclusion, or the preventive sealing that stops re-entry after your pest operator finishes.
Attic Sanitizing & Decontamination
Signs you need it
You’ve had rodents removed by pest control but still smell urine in the hallway, or your HVAC intake is near the attic and you’re concerned about airborne pathogens from droppings.
What it costs in Shady Hollow
Attic sanitizing with enzyme treatment, HEPA vacuuming, and antimicrobial application runs $1.60-$3.40 per square foot, typically $2,800-$7,200 for Shady Hollow attic footprints.
How we do it
We suit in full PPE, HEPA-vacuum all surfaces, apply enzyme digester to break down urine proteins, follow with EPA-registered antimicrobial, and photograph the cleaned deck before any insulation work.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in the attic at dawn or dusk, find gnawed soffit or fascia, or have had multiple pest control visits that trapped animals but didn’t address how they enter.
What it costs in Shady Hollow
Rodent proofing with 1/4-inch hardware cloth, copper mesh, and sealant at all penetration points runs $1,200-$3,800 for a typical Shady Hollow home, depending on roof complexity and entry point count.
How we do it
We inspect the roofline, soffits, vents, and utility penetrations with a lift or ladder, install rodent-resistant materials at every gap larger than 1/4 inch, and deliver a written map of sealed locations with photos.
What Attic Cleaning & Rodent Proofing Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Attic sanitizing & decontamination | $2,800 - $7,200 |
| Rodent proofing & exclusion | $1,200 - $3,800 |
| Full attic restoration (cleaning + proofing + insulation) | $6,500 - $14,500 |
Do you trap rodents or just seal the house?
We do not trap or bait - we seal the structure so rodents cannot re-enter, and we coordinate with your pest control operator who handles population reduction. Our written scope specifies every sealed location so you can verify the work. Call (737) 337-8049 for a free inspection.
How do I know if my attic is contaminated?
Visible droppings, urine staining on insulation or decking, compressed rodent runways through blown-in material, or the smell of ammonia near the attic hatch are all definitive signs. We inspect during our free estimate and photograph everything; we do not quote sanitizing without documenting why it is necessary. Call (737) 337-8049.
Home Energy Audit in Shady Hollow
A home energy audit in Shady Hollow is the diagnostic starting point we recommend for any homeowner who wants to prioritize spending across multiple envelope deficiencies, because the 1980s and 1990s construction here typically presents several simultaneous problems - attic air leaks, under-insulated walls, duct leakage, and crawl space moisture - and fixing them in the wrong order wastes money. Home Energy Audit gives you a ranked, written scope with blower-door and thermal-imaging documentation so you can see exactly where conditioned air is escaping and heat is entering.
Blower Door Test
Signs you need it
Your energy bills are 30% higher than neighbors with similar homes, you feel drafts despite closed windows, or you’re planning insulation work and want a baseline to verify improvement.
What it costs in Shady Hollow
A standalone blower-door test with written report runs $280-$580 in Shady Hollow; when bundled with thermal imaging and insulation inspection, the full audit is $450-$920.
How we do it
We install a calibrated blower door in an exterior doorway, depressurize the house to 50 Pascals, measure CFM50 leakage, and use smoke pencils and infrared cameras to locate the dominant leak paths while the fan runs.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach setpoint, you suspect missing insulation in walls or ceilings, or you want visual proof of envelope defects before committing to repair work.
What it costs in Shady Hollow
Thermal imaging as part of a full energy audit is included in the $450-$920 range; a standalone infrared inspection with report runs $320-$680 here.
How we do it
We scan the interior with a FLIR camera during normal heating or cooling operation, then repeat with the blower door running to exaggerate temperature differences, and mark every anomaly on a floor plan you keep.
What Home Energy Audit Costs in Shady Hollow
| Item | Typical range in Shady Hollow |
|---|---|
| Blower-door test with written report | $280 - $580 |
| Full energy audit (blower door + thermal + insulation + ducts) | $450 - $920 |
| Thermal imaging inspection (standalone) | $320 - $680 |
Will the audit tell me what to fix first?
Yes, the written report ranks recommendations by cost-effectiveness and comfort impact, with estimated savings for each measure; most Shady Hollow audits show attic air sealing and insulation as the highest-ROI first step. Call (737) 337-8049 to schedule - the audit fee applies toward any work you contract within 90 days.
How long does a home energy audit take?
Plan on three to four hours for a full audit, including setup, testing, interior and exterior inspection, and a walkthrough of preliminary findings. You receive the written report with photos, thermal images, and the ranked scope within two business days. Call (737) 337-8049 to book.
