Round Rock’s Dell-era housing stock - built fast, built to minimum code, and now aging through its first major envelope failures - creates a predictable pattern of insulation problems we see from Oak Creek to Round Rock Glen. The clay soils, seasonal deluges, and 150°F attic temperatures compound the original construction shortcuts. We dispatch crews locally from our Austin office, and every Round Rock job follows Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
Why Round Rock Homes Are Different
Round Rock’s explosive growth during the Dell Technologies boom produced a remarkably uniform housing stock: 1990s-2010s two-story brick-veneer tract homes across ZIP codes 78664, 78665, and 78681, nearly all built with minimum-code blown fiberglass at R-22 to R-30. That insulation has now compacted well below its original rating, and the vented attics with flex-duct HVAC runs create a double failure point we don’t see in newer builds near Kalahari and State Highway 45.
The IECC Climate Zone 2 designation means eight-plus months of cooling load, with attic temperatures that cook standard materials. Summer thunderstorms off West Palm Valley Boulevard drive moisture through ridge vents, clumping fiberglass and rusting hangers. In neighborhoods like Eagle Ridge and Chandler Crossing, we regularly find HVAC ducts wrapped in thin, degraded flex insulation that needs re-wrapping before any attic upgrade makes sense. The soil is heavy clay that holds crawl space moisture against foundation walls for weeks after rain. These conditions don’t just age insulation faster - they change the sequence of repairs.
Our Main Round Rock Services
Most Round Rock calls start with attic work or spray foam; here’s what homeowners in Oak Creek and Old Round Rock ask about first.
Attic Insulation in Round Rock
Attic insulation in Round Rock means dealing with compressed, moisture-clumped fiberglass in vented attics that hit 150°F. We remove the degraded material, seal top plates and can lights, then install new insulation to current IECC standards. Every attic job includes before-and-after blower-door numbers so you can verify the air-sealing result. Attic Insulation in Round Rock covers the full process for Dell-era homes and newer construction alike.
Spray Foam Insulation in Round Rock
Spray foam insulation in Round Rock works best for open attics, rim joists, and crawl space walls where air sealing and insulation need to happen simultaneously. We specify open-cell or closed-cell based on the assembly - closed-cell for below-grade and moisture-prone areas, open-cell for roof decks with proper vapor management. Spray Foam Insulation in Round Rock details material selection and pricing for local conditions.
Blown-In Insulation in Round Rock
Blown-in insulation in Round Rock is the most common replacement for original tract-home fiberglass, but we never blow new material over an unsealed attic floor. The top plates, electrical penetrations, and duct boots get sealed first - then we blow Knauf or Johns Manville cellulose or fiberglass to the specified depth with depth markers visible for inspection. Blown-In Insulation in Round Rock explains the sealed-first protocol and R-value targets for Climate Zone 2.

Crawl Space Encapsulation & Vapor Barrier in Round Rock
Crawl space encapsulation in Round Rock addresses the clay-soil moisture that wicks through block walls and evaporates into floor joists, creating the musty, humid conditions we find in homes from Behrens Ranch to Cimarron. A proper encapsulation isn’t a plastic sheet on the dirt - it’s a sealed building assembly with vapor barrier, sealed vents, conditioned air supply or dehumidification, and insulation where appropriate. Crawl Space Encapsulation & Vapor Barrier details our full protocol; here’s how we handle the most common Round Rock scenarios.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, visible mold on floor joists, or a musty smell that rises through the first floor in humid months.
What it costs in Round Rock
A 6-mil to 20-mil vapor barrier installed over bare earth typically runs $1,200-$2,400 for a standard Round Rock crawl space.
How we do it
We remove debris, grade the soil, seam-seal the barrier at all overlaps, and mechanically fasten it to foundation walls with termination bars.
Crawl Space Encapsulation
Signs you need it
Your HVAC ducts in the crawl space sweat in summer, insulation falls from the band joist, or your energy bills spike despite recent attic work.
What it costs in Round Rock
Full encapsulation with sealed vents, vapor barrier, and dehumidifier typically runs $3,200-$6,800 in Round Rock’s standard tract-home crawl spaces.
How we do it
We seal all vents and penetrations, install reinforced vapor barrier on walls and floor, add a dedicated dehumidifier with condensate pump, and verify with humidity readings.
What Crawl Space Encapsulation & Vapor Barrier Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Vapor barrier only (6-20 mil) | $1,200 - $2,400 |
| Full encapsulation with dehumidifier | $3,200 - $6,800 |
| Crawl space insulation (board or spray foam) | $1,800 - $3,600 |
How long does crawl space encapsulation take in Round Rock?
Most standard tract-home encapsulations finish in two to three days, with the dehumidifier running 48 hours before final humidity verification. We schedule around Round Rock’s spring storm season to avoid working in active water intrusion.
Will encapsulation fix my musty smell?
Yes, when the source is crawl space moisture - we verify with a humidity meter reading below 60% RH before calling the job complete. If the smell persists, we investigate plumbing leaks or exterior drainage issues.
Radiant Barrier Installation in Round Rock
Radiant barrier installation in Round Rock targets the dominant cooling-load problem: attic surfaces that reach 150°F and radiate heat downward through ductwork and ceiling drywall. In Dell-era homes with dark shingles and minimal original ventilation, a properly installed radiant barrier can reduce attic radiant heat gain by 20-40%, which matters more here than in any northern market. Radiant Barrier Installation covers material specs; here’s what Round Rock homes need.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 PM, your AC runs continuously on sunny days, or your ceiling drywall is warm to the touch in summer.
What it costs in Round Rock
Attic radiant barrier installation for a standard two-story tract home typically runs $1,400-$2,800 in Round Rock.
How we do it
We staple perforated foil to the underside of roof rafters, maintaining the required air gap and avoiding compression against the roof deck.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing a Dell-era home and want the radiant barrier integrated at the deck level rather than retrofitting to rafters later.
What it costs in Round Rock
Radiant barrier roof deck application during re-roofing typically adds $1,800-$3,200 to the project in Round Rock.
How we do it
We apply foil-faced sheathing or liquid radiant barrier coating to the roof deck before shingle installation, ensuring proper emissivity ratings.
What Radiant Barrier Installation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Attic radiant barrier (foil to rafters) | $1,400 - $2,800 |
| Radiant barrier roof deck (during re-roof) | $1,800 - $3,200 |
| Radiant barrier with attic ventilation upgrade | $2,200 - $4,000 |
Does radiant barrier work with my existing insulation?
Yes - radiant barrier addresses radiant heat transfer, while insulation addresses conductive heat flow; they complement each other and we specify both when attic temperatures exceed 140°F.
Will radiant barrier help my ducts in the attic?
It reduces the radiant heat load on duct surfaces, but we still recommend duct re-wrapping and sealing - the flex-duct insulation in Eagle Ridge and Chandler Crossing homes is typically degraded beyond recovery.
Insulation Removal & Replacement in Round Rock
Insulation removal and replacement in Round Rock is often the first step in any attic upgrade, because the original blown fiberglass has compacted, clumped from moisture intrusion, or been contaminated by rodent activity. In 1990s-2000s subdivisions, we find insulation that tests at R-15 or lower despite original R-30 labels - the material is still there, but the trapped air spaces that provide insulation value are gone. Insulation Removal & Replacement details our containment and disposal process; here’s how we handle Round Rock’s specific conditions.
Contaminated Insulation Removal
Signs you need it
You see rodent droppings, urine staining, or mold on the insulation surface, or you smell ammonia when the attic hatch is opened.
What it costs in Round Rock
Contaminated insulation removal with HEPA containment and disposal typically runs $1,800-$3,600 for a standard Round Rock attic.
How we do it
We establish negative air pressure, remove material in sealed bags, HEPA-vacuum all surfaces, and apply antimicrobial treatment before any new insulation goes in.
Insulation Replacement
Signs you need it
Your insulation is compacted below the joist tops, has dark staining from air leakage, or was installed before 2005 and never upgraded.
What it costs in Round Rock
Insulation replacement with air sealing and new blown cellulose or fiberglass typically runs $2,400-$4,800 in Round Rock’s standard two-story homes.
How we do it
We remove old material, seal all top plates and penetrations with foam and caulk, install baffles at eaves, and blow new insulation to current IECC depth with verified coverage.
What Insulation Removal & Replacement Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Contaminated insulation removal | $1,800 - $3,600 |
| Standard insulation removal (non-contaminated) | $1,200 - $2,400 |
| Insulation replacement with air sealing | $2,400 - $4,800 |
Do I have to leave during insulation removal?
No - we contain the work zone and run negative air machines, but you can remain in the home; we notify you before the blower-door test that follows.
How do I know if my insulation is contaminated?
We inspect during our initial assessment and photograph findings for your record; visible droppings, staining, or ammonia odor are clear indicators, and we test for vermiculite before disturbing any pre-1990 material.
Attic Air Sealing in Round Rock
Attic air sealing in Round Rock is the prerequisite step we never skip - blowing new insulation over an unsealed attic floor is, under our protocol, not an option. The Dell-era construction method left top plates, wire penetrations, and can lights poorly sealed; combined with the stack effect in two-story homes, this leaks conditioned air into the attic at rates we measure in thousands of CFM50. Attic Air Sealing explains the full protocol; here’s what Round Rock homes need.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage, you feel drafts at outlets on exterior walls, or your attic insulation has dark staining at the edges.
What it costs in Round Rock
Top plate and penetration sealing for a standard two-story home typically runs $1,400-$2,800 in Round Rock.
How we do it
We foam-seal all top plate joints, caulk wire and pipe penetrations, and install fire-rated covers over non-IC can lights before insulation covers them.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in windy weather, your duct boots show dust streaks from air leakage, or rooms at the end of duct runs never reach set temperature.
What it costs in Round Rock
Can light and duct boot sealing with proper covers and mastic typically runs $800-$1,600 for a standard Round Rock attic.
How we do it
We install pre-formed fire-rated boxes over can lights, seal duct boots with mastic and mesh, and verify with blower-door subtraction testing.
What Attic Air Sealing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Top plate and penetration sealing | $1,400 - $2,800 |
| Can light and duct boot sealing | $800 - $1,600 |
| Full attic air sealing (comprehensive) | $2,200 - $4,400 |
Can air sealing alone lower my bills?
Yes - we’ve measured 15-25% reduction in cooling load from air sealing alone in Dell-era Round Rock homes, though we recommend pairing with insulation replacement for maximum effect.
How do you prove the sealing worked?
We provide before-and-after blower-door numbers - a pressurization reading that shows, in one figure, how much conditioned air your home was losing before and after our work.
Wall Insulation in Round Rock
Wall insulation in Round Rock addresses the hollow 2×4 exterior walls common in 1990s-2000s tract construction, which were typically insulated with R-11 fiberglass batts that have settled or degraded. Unlike attics, walls can’t be visually inspected without invasive work, so we use thermal imaging to identify gaps and injection methods to add density without full demolition. Wall Insulation covers material options; here’s how we handle Round Rock’s specific wall assemblies.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, your rooms have uneven temperatures despite good attic insulation, or your siding was removed for other repairs.
What it costs in Round Rock
Injection foam wall insulation for a standard two-story home typically runs $3,200-$6,400 in Round Rock.
How we do it
We drill 2-inch holes at stud bay intervals, inject slow-rise foam to fill voids without bowing drywall, patch and texture-match the holes.
Drill & Fill Wall Insulation
Signs you need it
Your walls have no insulation (common in garage-adjacent rooms and additions), or your original batts have fallen to the bottom of the cavity.
What it costs in Round Rock
Drill-and-fill with dense-pack cellulose for a standard home typically runs $2,400-$4,800 in Round Rock.
How we do it
We drill access holes, dense-pack cellulose to 3.5 pounds per cubic foot for no-settle performance, and seal holes with matching plugs.
What Wall Insulation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Injection foam wall insulation | $3,200 - $6,400 |
| Drill-and-fill cellulose | $2,400 - $4,800 |
| Exterior wall insulation (during re-siding) | $4,000 - $8,000 |
Will wall insulation mess up my drywall?
Injection methods require patching, but we texture-match to existing finish; the best time to do this is during interior painting or exterior siding replacement.
How do you know if my walls are empty?
We use thermal imaging during our energy audit to identify temperature differentials that indicate missing or settled insulation, then confirm with a borescope inspection through a single test hole.
Attic Cleaning & Rodent Proofing in Round Rock
Attic cleaning and rodent proofing in Round Rock addresses the entry and contamination patterns we see in mature subdivisions where mature trees, utility lines, and roof-soffit intersections create highway systems for roof rats and squirrels. The original construction left gaps at fascia boards, pipe penetrations, and attic vents that rodents exploit; once inside, they compress insulation, contaminate it, and create fire hazards by chewing wiring. Attic Cleaning & Rodent Proofing details our full protocol; here’s what Round Rock homes need.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at night, find droppings in the attic, or see chew marks on fascia boards or vent screens.
What it costs in Round Rock
Rodent proofing and exclusion for a standard two-story home typically runs $1,200-$2,400 in Round Rock.
How we do it
We seal all entry points larger than 1/4 inch with metal flashing, hardware cloth, and foam, install ridge vent guards, and provide photo documentation of every sealed location.
Attic Sanitizing & Decontamination
Signs you need it
You smell ammonia or musk in the attic, see urine staining on insulation or joists, or have had rodents present for more than one season.
What it costs in Round Rock
Attic sanitizing and decontamination with HEPA removal and antimicrobial treatment typically runs $1,800-$3,600 in Round Rock.
How we do it
We remove contaminated material in sealed bags, HEPA-vacuum all surfaces, apply enzyme-based sanitizer, and verify with ATP testing before any new insulation is installed.
What Attic Cleaning & Rodent Proofing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Rodent proofing and exclusion | $1,200 - $2,400 |
| Attic sanitizing and decontamination | $1,800 - $3,600 |
| Full attic restoration (removal, sanitize, re-insulate) | $4,000 - $8,000 |
How do rodents get into Round Rock attics?
Roof rats travel utility lines and tree branches to roof intersections, then squeeze through gaps at fascia boards, vent screens, or pipe penetrations - we map and photograph every entry point.
Will they come back after you seal?
Our exclusion work carries a one-year guarantee; if rodents re-enter through any location we sealed, we return at no charge to reinforce the barrier.
Home Energy Audit in Round Rock
A home energy audit in Round Rock gives Dell-era homeowners the documentation they need to prioritize envelope improvements against the backdrop of predictable, repeated construction failures. The audit identifies where conditioned air escapes, where insulation has failed, and which repairs will yield the fastest payback in a market with eight months of cooling load. Home Energy Audit details our full diagnostic protocol; here’s what Round Rock homeowners receive.
Blower Door Test
Signs you need it
Your energy bills are rising despite no rate increase, rooms have uneven temperatures, or you’re planning major insulation work and want a baseline.
What it costs in Round Rock
A standalone blower-door test with written report typically runs $300-$500 in Round Rock; it’s credited toward any work we perform.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, and measure CFM50 to quantify total envelope leakage.
Thermal Imaging Inspection
Signs you need it
You suspect missing wall insulation, want to locate air leaks behind drywall, or need documentation for an insurance or warranty claim.
What it costs in Round Rock
Thermal imaging with blower-door testing typically runs $400-$700 in Round Rock, including a photo report with annotated findings.
How we do it
We run the blower door to exaggerate leakage paths, then scan with an infrared camera to visualize temperature differentials that indicate missing insulation or air infiltration.
What Home Energy Audit Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Blower-door test with written report | $300 - $500 |
| Thermal imaging with blower door | $400 - $700 |
| Full home energy audit (comprehensive) | $500 - $900 |
How long does an energy audit take?
A comprehensive audit takes three to four hours for a standard two-story home, including setup, testing, and a walkthrough of preliminary findings with you on-site.
Will the audit tell me what to fix first?
Yes - we prioritize repairs by cost-effectiveness and comfort impact, with estimated savings for each measure, so you can phase work according to your budget.
