Insulation in Round Rock, TX
Crawl space encapsulation and vapor barrier installation in Round Rock typically runs $3,500-$7,500 for most homes, with full encapsulations on larger crawl spaces reaching the upper end. We see more moisture-damaged fiberglass down there than almost anywhere in Central Texas - the clay soils hold water, and the 1990s-2000s production homes were built with minimal ground separation. If you’re seeing musty odors, sagging insulation, or higher-than-expected summer humidity readings, call (254) 970-2136. We’ll give you a written price before any work starts, and every encapsulation includes a documented photo record of the completed job.
Why Round Rock Homes Are Different
Round Rock’s explosive Dell-driven growth from the 1990s through the 2000s produced one of the densest concentrations of production-built suburban homes in Central Texas - all constructed to the minimal insulation standards of that era. That single decade-long building boom means the city now has a massive, geographically concentrated retrofit market: tens of thousands of homes with settled, degraded blown fiberglass attics hovering around R-22 or less, in a climate where attic temps routinely exceed 150°F and where Winter Storm Uri (February 2021) exposed how unprepared the same homes were for hard freezes.
In neighborhoods like Forest Creek and Teravista - built out quickly in the late 1990s and early 2000s - technicians pulling attic hatches almost universally find blown fiberglass with no air-sealing at top plates, recessed-light penetrations open to conditioned space, and settled depths well below code minimums. Because entire subdivisions were built by the same builder in the same 18-month window, a single street canvas often yields a full week of identical retrofit scopes. The clay soils and seasonal moisture swings also mean crawl spaces here fail faster than in Hill Country homes on rockier ground.
Our Main Round Rock Services
Round Rock homeowners call us most often for attic work and spray foam - the two upgrades that deliver the fastest payback in this climate. Here is what each job looks like here.
Attic Insulation in Round Rock
Most Round Rock attics we enter have original blown fiberglass settled to R-19 or less, with no air sealing at the top plates - the horizontal framing member where exterior walls meet the ceiling. We pull the existing material, seal every penetration, then reinstall to R-38 or R-49 depending on the roof geometry. In Teravista and Forest Creek, we have documented the same failure pattern across dozens of homes: 4,200 CFM50 blower-door readings dropping to 2,100 after proper sealing and reinsulation. Attic Insulation in Round Rock includes before-and-after blower-door numbers on every job.
Spray Foam Insulation in Round Rock
Open-cell spray foam at the roof deck is the most common fix for bonus rooms and converted attics in Round Rock’s two-story production homes, where the original builder left the attic floor unsealed and the upstairs bedrooms bake all summer. We use Icynene and Demilec products, applied to the underside of the roof sheathing to bring the attic into the conditioned envelope. Closed-cell foam at the rim joist - the perimeter framing where the first floor meets the foundation - stops the air leaks that pull crawl space moisture into living spaces. Spray Foam Insulation in Round Rock jobs get a written scope and written warranty before application begins.
Blown-In Insulation in Round Rock
Blown-in fiberglass or cellulose is still the most cost-effective way to bring a settled Round Rock attic back to current IECC code. We see the worst settling in homes built 1998-2004, where original installers blew to minimum depth and the material compacted over two decades of 150°F summers. We use Owens Corning and GreenFiber products, installed over a fully sealed attic floor. Every job gets a depth check photo every 100 square feet, included in the documented photo record. Blown-In Insulation in Round Rock typically pays for itself in 4-7 years on utility bills.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Round Rock
Round Rock’s clay-heavy soils and seasonal moisture swings destroy fiberglass crawl space insulation faster than almost anywhere we work in Central Texas. The production homes built during the Dell boom typically had 6-mil vapor barriers laid loosely on dirt floors, if anything at all, with R-19 batts strapped to the underside of the first-floor joists. Those batts sag, grow mold, and eventually fall - we find them rotting on the ground in roughly half the crawl spaces we inspect in neighborhoods like Behrens Ranch and Cat Hollow. Crawl Space Encapsulation & Vapor Barrier work here always begins with a full assessment of ground moisture, foundation vents, and rim joist air leakage before we specify the encapsulation scope.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, visible mold on joists or insulation, or a persistent musty smell that enters the living space through floor penetrations.
What it costs in Round Rock
A 6-mil to 20-mil vapor barrier installation for a standard Round Rock crawl space runs $1,200-$2,800, with thicker reinforced membranes and full seam sealing at the higher end.
How we do it
We remove all degraded material, grade the soil for drainage, lay and seam-seal the barrier to foundation walls, then seal wall penetrations with closed-cell foam before reinstalling any necessary insulation.
Crawl Space Encapsulation
Signs you need it
You’re running a dehumidifier in the crawl space continuously, seeing rusted ductwork or HVAC components, or your hardwood floors are cupping from below-grade moisture migration.
What it costs in Round Rock
Full encapsulation with sealed vents, dehumidification, and insulated walls for a typical Round Rock crawl space ranges from $4,500-$8,500 depending on square footage and existing damage.
How we do it
We seal all vents, install a reinforced vapor barrier sealed to walls, apply closed-cell foam to the foundation walls and rim joist, then size and install a dedicated dehumidifier with a condensate pump to outside.
What Crawl Space Encapsulation & Vapor Barrier Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Vapor barrier (6-20 mil, standard crawl space) | $1,200 - $2,800 |
| Full encapsulation with dehumidifier | $4,500 - $8,500 |
| Crawl space insulation replacement (after encapsulation) | $1,800 - $3,500 |
How long does crawl space encapsulation take in Round Rock?
Most encapsulations finish in 2-3 days: one day for prep and material removal, one for barrier and foam installation, and a partial day for dehumidifier setup and testing. Clay soils with poor drainage may need a pre-installation drainage assessment that adds a day.
Will encapsulation fix my musty smell?
Yes, if the source is ground moisture evaporating into the crawl space - sealing the vapor path and controlling humidity eliminates the odor within 48-72 hours of dehumidifier operation. If the smell persists, we investigate duct leakage or plumbing vents as secondary sources.
Radiant Barrier Installation in Round Rock
Round Rock attics hit 150°F regularly from May through September, and the original radiant barriers - if installed at all in 1990s-2000s production homes - were often thin, poorly attached, or degraded by dust accumulation. We install new radiant barrier systems that reduce attic surface temperatures by 20-30°F, which directly lowers the cooling load on ductwork running through those spaces. In homes with dark shingle roofs and minimal existing ventilation, the payback period can be under 5 years. Radiant Barrier Installation in Round Rock is most effective when paired with adequate attic ventilation and proper air sealing.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot after sunset, your AC runs continuously on summer afternoons, or your ductwork in the attic feels hot to the touch.
What it costs in Round Rock
Attic radiant barrier installation for a typical 2,000-square-foot Round Rock home runs $1,500-$3,200 depending on roof complexity and whether we use foil sheets or spray-applied coating.
How we do it
We staple perforated foil across the bottom of rafters or spray a low-emissivity coating to the roof deck, ensuring a 1-inch air gap for convective cooling and verifying with an infrared thermometer.
Radiant Barrier & Ventilation
Signs you need it
Your attic has no ridge vent or soffit vents, or existing vents are blocked by insulation, creating a stagnant heat reservoir that overwhelms any radiant barrier.
What it costs in Round Rock
Combined radiant barrier and ventilation upgrade with new soffit vents, baffles, and ridge vent installation typically costs $2,800-$5,500 in Round Rock’s production-home rooflines.
How we do it
We install baffles to maintain airflow from soffit to ridge, add or clear ventilation paths, then apply the radiant barrier - testing with a smoke pencil to confirm convective flow before we leave.
What Radiant Barrier Installation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Attic radiant barrier (foil or spray) | $1,500 - $3,200 |
| Radiant barrier with ventilation upgrade | $2,800 - $5,500 |
| Roof deck radiant barrier (new construction or re-roof) | $2,200 - $4,000 |
Does radiant barrier work with blown-in insulation?
Yes - radiant barrier addresses radiant heat transfer from the roof deck, while blown-in insulation slows conductive heat flow through the attic floor; they complement each other and we install both on most Round Rock retrofits.
How much will my attic temperature drop?
Properly installed radiant barrier typically reduces attic surface temperatures by 20-30°F and peak air temperatures by 10-20°F, though results vary with roof color, ventilation, and orientation; we measure before and after with an infrared thermometer.
Insulation Removal & Replacement in Round Rock
The blown fiberglass in Round Rock’s 1990s-2000s production homes has had 20-30 years to settle, compact, and in many cases become contaminated by roof leaks, rodent activity, or HVAC condensate. We remove insulation that has fallen below R-19 effective value, or that shows visible mold, urine staining, or water damage - conditions we find in roughly 40% of the attics we inspect in Dell-era neighborhoods. Replacement with modern material, installed over a sealed attic floor, typically doubles the thermal performance. Insulation Removal & Replacement jobs include full containment, HEPA filtration, and documented disposal records.
Contaminated Insulation Removal
Signs you need it
Your attic insulation shows dark staining, a strong ammonia smell, visible droppings, or you’ve had a roof leak that saturated the material.
What it costs in Round Rock
Contaminated insulation removal with full PPE, negative-air containment, and disposal for a standard Round Rock attic runs $1,800-$3,500, with severe contamination requiring additional sanitizing at the higher end.
How we do it
We establish negative air pressure with HEPA scrubbers, remove material in sealed bags, apply an enzyme-based sanitizer to exposed surfaces, then inspect the deck for damage before any new insulation goes in.
Insulation Replacement
Signs you need it
Your attic has been empty since a previous removal, or the existing material is uniformly settled below joist level with no air sealing underneath.
What it costs in Round Rock
Full replacement with new blown-in fiberglass or cellulose to R-38, installed over sealed top plates and penetrations, typically costs $2,500-$5,000 for a 2,000-square-foot Round Rock home.
How we do it
We complete full air sealing first, install baffles at every eave, then blow to specified depth with depth markers every 100 square feet - verified with photos in your documented record.
What Insulation Removal & Replacement Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Contaminated insulation removal | $1,800 - $3,500 |
| Insulation replacement (blown-in to R-38) | $2,500 - $5,000 |
| Removal + replacement package | $3,800 - $7,500 |
Do I have to leave during removal?
No - our containment and negative-air setup keeps living spaces isolated, though we recommend sensitive individuals stay elsewhere for the 4-6 hour removal window as a precaution.
Can you remove insulation with asbestos?
We do not handle asbestos-containing material; if your Round Rock home was built before 1985 and has vermiculite insulation, we arrange certified abatement before our crew enters - call (254) 970-2136 and we’ll help you identify what you have.
Attic Air Sealing in Round Rock
The production builders working Round Rock’s boom years sealed almost nothing - top plates were left open, recessed lights cut into ceilings with no enclosure, and duct boots pulled away from drywall by seasonal expansion and contraction. A blower-door test on a typical Forest Creek home from 2002 reads 4,000-5,000 CFM50 before we start; after sealing top plates, can lights, penetrations, and duct boots, we regularly see 2,000-2,500 CFM50. That reduction - 40-50% less conditioned air escaping - is the single most cost-effective upgrade we offer, and we won’t install new insulation over an unsealed attic floor. Attic Air Sealing is always step one in our process.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive leakage, you feel drafts at ceiling outlets in winter, or your attic hatch has visible gaps around the perimeter.
What it costs in Round Rock
Top plate and penetration sealing for a standard Round Rock production home runs $1,200-$2,800, with complex rooflines and multiple chimney penetrations at the higher end.
How we do it
We pull back existing insulation, foam-seal every top plate joint and wire penetration with one-part foam, then cover with fire-rated caulk where required before reinstalling insulation.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights are standard non-IC housings with no airtight cover, or your supply registers blow less air than expected because the duct boot has separated from the ceiling.
What it costs in Round Rock
Can light sealing with fire-rated covers and duct boot reconnection typically costs $800-$1,800 in Round Rock’s standard 2,000-square-foot homes with 8-12 can lights.
How we do it
We install pre-formed airtight boxes over each can light, seal with fire-rated caulk, then reconnect and mastic-seal duct boots to the ceiling plane - verified with a smoke pencil under depressurization.
What Attic Air Sealing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Top plate and penetration sealing | $1,200 - $2,800 |
| Can light and duct boot sealing | $800 - $1,800 |
| Full attic air sealing (comprehensive) | $2,500 - $4,500 |
Will air sealing alone lower my bills?
Yes - we have documented 15-25% cooling load reduction in Round Rock homes after air sealing only, though combining it with insulation replacement to R-38 or R-49 delivers the full performance.
How do you prove the sealing worked?
Every job includes before-and-after blower-door numbers - a pressurization reading that shows, in one figure, how much air your building envelope was losing before and after our work.
Wall Insulation in Round Rock
Round Rock’s production homes from the Dell era were framed with 2x4s and insulated with R-13 fiberglass batts - barely adequate when new, and often poorly installed with compression gaps and unsealed electrical boxes. Exterior walls in these homes account for 15-20% of total heat loss in winter and heat gain in summer, yet they’re the hardest to address after construction. We use injection foam and drill-and-fill methods that don’t require interior demolition, making retrofit wall insulation practical for occupied homes. Wall Insulation in Round Rock is most commonly requested after homeowners complete attic work and still feel thermal discomfort at exterior walls.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, cold in winter, or you can hear outdoor noise clearly through closed windows and intact walls.
What it costs in Round Rock
Injection foam wall insulation for a typical 2,000-square-foot Round Rock home runs $3,500-$6,500, with two-story homes and complex wall geometries at the higher end.
How we do it
We drill 2-inch holes at stud spacing from the exterior, inject slow-rise foam that fills cavities without bowing drywall, then seal plugs with matching siding or mortar.
Drill & Fill Wall Insulation
Signs you need it
Your walls have empty cavities from removed or settled batts, or you’re remodeling and have temporary access to stud bays before drywall goes up.
What it costs in Round Rock
Drill-and-fill with dense-pack cellulose for accessible Round Rock wall cavities typically costs $2,800-$5,000, with interior access reducing cost by 20-30% compared to exterior drilling.
How we do it
We access cavities through interior drywall cuts or exterior holes, blow cellulose to 3.5 pounds per cubic foot density for no-settle performance, then repair access points.
What Wall Insulation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Injection foam (exterior access) | $3,500 - $6,500 |
| Drill-and-fill cellulose | $2,800 - $5,000 |
| Interior wall soundproofing (Rockwool) | $4,000 - $7,500 |
Will injection foam damage my drywall?
No - we use slow-rise formulations at controlled pressure that fill without expansion force; in 9,000+ jobs since 2016, we have not had a drywall failure from injection foam.
Can you insulate walls without removing drywall?
Yes - exterior drill-and-fill or injection foam methods require only small access holes that we seal with matching materials; interior walls need baseboard or minimal cut access.
Attic Cleaning & Rodent Proofing in Round Rock
Round Rock’s mature neighborhoods - Forest Creek, Teravista, Behrens Ranch - have tree canopies that connect rooflines to squirrel and rat highways, and the original construction left attic vents unscreened and eave gaps open. We find active rodent traffic in roughly 30% of the attics we inspect in these areas, with contamination ranging from isolated droppings to fully saturated insulation requiring complete removal. Our process addresses the entry points first, then cleans and sanitizes, then restores - because new insulation installed over active infestation is wasted money. Attic Cleaning & Rodent Proofing includes a one-year re-entry guarantee on all exclusion work.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in ceilings at dawn or dusk, find droppings in the attic, or see chew marks on fascia boards and vent screens.
What it costs in Round Rock
Rodent proofing and exclusion for a standard Round Rock home with 4-6 entry points runs $1,500-$3,200, with extensive roofline complexity or multiple species requiring additional trapping protocols.
How we do it
We inspect every roof penetration with a camera, seal entry points with rodent-proof materials (steel mesh, concrete, metal flashing), then install vent screens and verify with a follow-up inspection.
Attic Sanitizing & Decontamination
Signs you need it
Your attic has visible droppings, urine staining on insulation or decking, or a persistent organic odor that enters the living space through recessed lights and duct leaks.
What it costs in Round Rock
Attic sanitizing and decontamination with enzyme treatment, HEPA vacuuming, and surface sealing typically costs $1,200-$2,800 in Round Rock’s standard production-home attics.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzyme sanitizer to break down organic matter, then seal stained decking with encapsulant paint before any new work begins.
What Attic Cleaning & Rodent Proofing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Rodent proofing and exclusion | $1,500 - $3,200 |
| Attic sanitizing and decontamination | $1,200 - $2,800 |
| Full attic restoration (removal, clean, re-insulate) | $4,500 - $9,000 |
How do you find all the entry points?
We use a combination of roof-level inspection, attic camera survey, and exterior thermal imaging to identify air leaks that rodents follow; every entry point is documented with a photo in your record.
Will rodents chew through spray foam?
Yes - we never use spray foam as the sole rodent barrier; our exclusion work relies on steel mesh, concrete, and metal flashing that rodents cannot penetrate, with foam used only for air sealing behind those barriers.
Home Energy Audit in Round Rock
A home energy audit in Round Rock reveals the specific failure pattern of your Dell-era production home - whether it’s the unsealed top plates we find in Teravista, the uninsulated rim joists in Cat Hollow, or the duct leakage pulling 150°F attic air into conditioned space. Our audit protocol includes a blower-door test, thermal imaging, and combustion safety checks; the documented report gives you a prioritized scope with expected savings for each measure. We deliver this as a written price before any work starts - Haven Standard Clause 1 - and offer a free second opinion on any competing audit’s recommendations. Home Energy Audit results are yours to keep, with no obligation to hire us for the work.
Blower Door Test
Signs you need it
Your utility bills are 30% or more above neighbors with similar homes, you feel persistent drafts, or you’re considering insulation work and want to measure the result.
What it costs in Round Rock
A standalone blower-door test with full air-leakage mapping runs $350-$650 in Round Rock, or it’s included at no charge when bundled with a comprehensive energy audit.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, then use a smoke pencil and infrared camera to locate and document every significant leak path.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach set temperature, suspect missing insulation in walls or ceiling, or want to verify contractor work before final payment.
What it costs in Round Rock
Thermal imaging inspection alone costs $250-$450 in Round Rock; combined with blower-door testing under controlled pressure differential, it reveals leaks invisible to visual inspection.
How we do it
We scan every interior and exterior surface with a FLIR camera during blower-door depressurization, then annotate images with R-value estimates and recommended corrections in the written report.
What Home Energy Audit Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Blower-door test (standalone) | $350 - $650 |
| Thermal imaging inspection | $250 - $450 |
| Comprehensive home energy audit | $450 - $850 |
Will the audit tell me what to fix first?
Yes - our report ranks measures by cost-effectiveness: air sealing almost always returns first in Round Rock’s production homes, followed by attic insulation, then duct sealing or wall insulation depending on your specific leakage pattern.
Can I use the audit for utility rebates?
Yes - our audit documentation meets Austin Energy and Texas Gas Service program requirements; we note eligible measures in the report and can coordinate submission if you proceed with our recommended scope.
