Insulation in Round Rock, TX
Most Round Rock homes built during the Dell boom of the 1990s through mid-2000s were insulated to the then-minimum R-30 attic standard, and after 20-30 years of Central Texas heat cycling, that original fiberglass has settled and degraded in ways homeowners feel in both summer electric bills and winter pipe freezes. Crawl space encapsulation and vapor barrier work is less common here - nearly all Round Rock residential construction is slab-on-grade with no crawl spaces - so our crews focus instead on attics, wall cavities, and radiant barriers for the single-story and two-story tract homes that dominate ZIP codes 78660, 78664, 78665, and 78681. Call (737) 252-7159 and we’ll send a written price before anyone lifts a tool.
Why Round Rock Homes Are Different
Round Rock sits in a climatic transition zone that delivers 100°F+ summer stretches with intense solar loading on low-pitched rooflines and periodic hard freezes - the same attic that bakes in July was exposed as dangerously under-insulated during the February 2021 Winter Storm Uri freeze. In the Dell-boom subdivisions along FM 685 and east of I-35, builders commonly skipped radiant barriers to hit price points, leaving west-facing rooflines with no reflective layer. We see this repeatedly in attics across Chandler Crossing and Lake Forest, where afternoon attic temps routinely exceed 155°F. The housing stock is overwhelmingly slab-on-grade from the 1993-2015 build era, meaning insulation work centers on attics and wall cavities rather than crawl spaces. Homes in Oak Creek and Old Round Rock face the same thermal stress but with varying roof geometries that change how we approach air sealing and ventilation. Dispatch and scheduling for Round Rock jobs are coordinated from our Austin office, with crews serving the area locally.
Our Main Round Rock Services
Round Rock homeowners call us most often for attic work and spray foam applications - here is what each involves in this market.
Attic Insulation in Round Rock
Attic insulation in Round Rock typically means upgrading compressed fiberglass batts or minimally-blown loose fill that has degraded under decades of 150°F+ attic temperatures. We start with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - then seal before we insulate. Attic Insulation in Round Rock jobs in neighborhoods like Round Rock Glen often reveal top plates and can lights leaking conditioned air directly into the attic space.
Spray Foam Insulation in Round Rock
Spray foam insulation in Round Rock works best for open attic floors and rim joist areas where air sealing and insulation must happen simultaneously. We use materials from Icynene and Demilec, applying closed-cell foam at critical junctions and open-cell where breathability matters. Spray Foam Insulation in Round Rock is particularly effective for the complex rooflines found in newer infill construction near West Palm Valley Boulevard.
Blown-In Insulation in Round Rock
Blown-in insulation in Round Rock is our most common retrofit for the Dell-era tract homes that need density and coverage without full removal. We use Owens Corning and GreenFiber loose-fill products, blown to the specified depth after air sealing is complete. Blown-In Insulation in Round Rock jobs typically follow our attic air sealing protocol so the new material doesn’t get compromised by ongoing air leaks.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Round Rock
Crawl space encapsulation and vapor barrier work in Round Rock is limited by the city’s slab-on-grade housing stock - nearly all residential construction here sits directly on concrete with no crawl space to treat. When we do encounter accessible crawl spaces, typically in rare older builds near Old Round Rock or specific commercial-adjacent structures, the same clay soils and humidity that affect the broader Austin metro create moisture problems that demand full encapsulation rather than partial fixes. Crawl Space Encapsulation & Vapor Barrier work follows the same Haven Standard protocol we apply everywhere: written price first, documented record at completion.
Crawl Space Vapor Barrier
Signs you need it
Standing water, musty odors rising through floor registers, or visible mold on joist ends indicate the soil vapor barrier has failed or was never installed.
What it costs in Round Rock
A 6-mil to 20-mil vapor barrier installation in Round Rock typically runs $1,200-$3,500 depending on square footage and seam-sealing requirements.
How we do it
We remove debris, grade the soil, lay overlapping polyethylene sheets with sealed seams, and mechanically fasten to walls to create a continuous moisture block.
Crawl Space Encapsulation
Signs you need it
Chronic humidity above 70% relative humidity, rotting sill plates, or pest activity in the crawl space mean partial measures are no longer sufficient.
What it costs in Round Rock
Full crawl space encapsulation in Round Rock generally ranges from $3,500-$8,000 for conditioned perimeter walls, sealed vents, and dehumidifier integration.
How we do it
We install rigid foam board on perimeter walls, seal all vents and penetrations, lay a reinforced vapor barrier across the floor, and add a dedicated dehumidifier with condensate pump.
What Crawl Space Encapsulation & Vapor Barrier Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Vapor barrier installation (6-20 mil) | $1,200 - $3,500 |
| Full encapsulation with dehumidifier | $3,500 - $8,000 |
| Crawl space insulation (rare, limited applications) | $2,000 - $5,500 |
How common are crawl spaces in Round Rock homes?
They are uncommon - nearly all Round Rock residential construction is slab-on-grade, so we encounter accessible crawl spaces in fewer than 5% of local jobs, typically in pre-1990 builds or commercial structures. Call (737) 252-7159 and we’ll assess what you have during a free estimate.
Can encapsulation help with indoor air quality?
Yes - sealing the crawl space blocks soil gases, mold spores, and pest allergens from entering the HVAC return paths, which is why we recommend it when the space exists. We document before-and-after humidity readings so you can verify the result.
Radiant Barrier Installation in Round Rock
Radiant barrier installation in Round Rock addresses one of the most common shortcuts from the Dell-boom build era: builders along FM 685 and east of I-35 routinely skipped reflective roof decking to hit price points, leaving west-facing rooflines with no defense against 155°F+ attic temperatures. After the February 2021 freeze exposed how poorly these same attics retain heat, Round Rock homeowners increasingly pair radiant barriers with blown-in upgrades for year-round performance. Radiant Barrier Installation is one of our highest-ROI recommendations for the low-pitched rooflines found across Chandler Crossing and Lake Forest.
Attic Radiant Barrier
Signs you need it
Attic temperatures exceeding 140°F on mild days, AC runtime extending past 6 PM, or second-floor rooms that never cool evenly with the thermostat set point.
What it costs in Round Rock
Attic radiant barrier installation in Round Rock typically runs $1,500-$3,500 for a standard single-story tract home, depending on roof complexity and access.
How we do it
We staple perforated aluminum foil across rafter bottoms or lay it over existing insulation, maintaining air gaps per manufacturer specifications for proper reflectivity.
Radiant Barrier Roof Deck
Signs you need it
New roof installation or re-roofing project where the decking is exposed, offering the only opportunity to install a structural radiant barrier without retrofit intrusion.
What it costs in Round Rock
Radiant barrier roof deck installation during re-roofing in Round Rock generally adds $1,200-$2,800 to the roofing scope, varying with square footage and pitch.
How we do it
We install foil-faced OSB or attach reflective sheathing directly to the roof deck before shingle installation, creating a permanent radiant barrier integrated with the roof structure.
What Radiant Barrier Installation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Attic radiant barrier (retrofit) | $1,500 - $3,500 |
| Radiant barrier roof deck (during re-roof) | $1,200 - $2,800 |
| Radiant barrier with attic insulation upgrade | $3,000 - $6,500 |
Does radiant barrier work with blown-in insulation?
Yes - we install the radiant barrier first, then blow insulation over or under it depending on the product type, so the two systems work together rather than competing. Call (737) 252-7159 for a written price on the combined scope.
How much can radiant barrier lower my electric bill?
Most Round Rock homeowners see attic heat gain reductions of 20-35% in summer months, with actual bill impact depending on AC efficiency, duct location, and how well the attic is already sealed - we measure this with a blower-door test before quoting.
Insulation Removal & Replacement in Round Rock
Insulation removal and replacement in Round Rock is often necessitated by the Dell-era housing stock’s original fiberglass batts, which have compressed and degraded after 20-30 years of thermal cycling in attics that routinely hit 150°F. We also encounter rodent-contaminated insulation in neighborhoods with mature tree canopy like Oak Creek, where roof rats have accessed attic spaces through unsealed eave gaps. Insulation Removal & Replacement always includes a full attic inspection and photo documentation before we quote the scope.
Attic Insulation Removal
Signs you need it
Insulation compressed below its original R-value, visible water staining, or uniform graying and breakdown of fiberglass batts indicate removal is preferable to topping off.
What it costs in Round Rock
Attic insulation removal in Round Rock typically runs $1,000-$2,500 for a standard single-story home, with pricing driven by square footage, access difficulty, and disposal fees.
How we do it
We use commercial vacuums with HEPA filtration to extract old material through contained hoses, bag it for proper disposal, and inspect the deck for air leaks or damage before replacement begins.
Contaminated Insulation Removal
Signs you need it
Strong ammonia odors, visible droppings, shredded insulation with nesting material, or recent pest activity confirmed by an exterminator require full removal and sanitization.
What it costs in Round Rock
Contaminated insulation removal with decontamination in Round Rock generally ranges from $2,000-$4,500, including PPE, HEPA containment, and antimicrobial treatment of exposed surfaces.
How we do it
We suit in full PPE, establish negative air containment, remove all contaminated material, apply enzyme-based sanitizers to the attic deck, and provide photo documentation before any new insulation is installed.
What Insulation Removal & Replacement Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Standard attic insulation removal | $1,000 - $2,500 |
| Contaminated insulation removal + decon | $2,000 - $4,500 |
| Removal + replacement with new blown-in | $3,500 - $7,500 |
Can you remove insulation without replacing it the same day?
We do not recommend it - an uninsulated attic in Round Rock’s climate creates immediate thermal stress and can spike your electric bill within days, so we schedule removal and replacement as a continuous scope. Call (737) 252-7159 to coordinate timing.
How do I know if my insulation is contaminated?
We inspect during our free estimate and show you the photos - visible droppings, nesting material, or saturated areas are documented before we quote removal, so you know exactly what we found rather than taking our word for it.
Attic Air Sealing in Round Rock
Attic air sealing in Round Rock is the single most overlooked upgrade in the Dell-boom housing stock, where builders prioritized speed over envelope integrity and left top plates, can lights, and duct boots unsealed against the attic. The February 2021 freeze proved how costly these leaks are - conditioned air escaping into the attic meant pipes froze in walls that should have stayed warm. Attic Air Sealing is always our first step before adding insulation, because blowing new material over unsealed leaks is simply hiding the problem.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling edges, cobwebs concentrated at wall-ceiling joints, or rooms that are consistently 5-10 degrees different from the thermostat setting indicate top plate leakage.
What it costs in Round Rock
Top plate and penetration sealing in Round Rock typically runs $800-$2,000 for a standard single-story home, depending on the number of interior walls and wiring penetrations.
How we do it
We access the attic floor, locate all top plates and wire/plumbing penetrations, seal with fire-rated caulk and expanding foam, and verify with a blower-door test before we leave.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that flicker in high winds, visible gaps around duct boots, or HVAC airflow that feels weak at distant registers suggest major leakage at these common failure points.
What it costs in Round Rock
Can light and duct boot sealing in Round Rock generally ranges from $600-$1,800, with pricing driven by the number of fixtures and whether they require fire-rated covers or simple gasket sealing.
How we do it
We install pre-formed fire-rated covers over can lights, seal duct boots with mastic and mesh, and pressure-test the system to confirm leakage reduction before closing the attic.
What Attic Air Sealing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Top plate & penetration sealing | $800 - $2,000 |
| Can light & duct boot sealing | $600 - $1,800 |
| Full attic air sealing (comprehensive) | $1,500 - $3,500 |
Do I need air sealing if I’m already adding insulation?
Yes - we will not blow insulation over an unsealed attic floor; air sealing is completed first so the new insulation performs at its rated R-value rather than being compromised by convective airflow. Call (737) 252-7159 for a written scope that shows both steps.
How do you prove air sealing worked?
We provide before-and-after blower-door numbers on every applicable job - a pressurization measurement that shows, in a single figure, how much conditioned air your home was losing before and after the work, documented in your photo record.
Wall Insulation in Round Rock
Wall insulation in Round Rock addresses the hollow exterior walls common in Dell-era tract homes, where fiberglass batts were often poorly fitted or omitted entirely in corners and behind electrical boxes. These walls perform even worse after settling and thermal bridging through studs - we regularly find 2×4 walls with effective R-values below R-8 in neighborhoods like Eagle Ridge and Behrens Ranch. Wall Insulation retrofits require careful technique to avoid interior damage, which is why we use injection methods developed for finished homes.
Injection Foam Wall Insulation
Signs you need it
Walls that are cold to the touch in winter, rooms with exterior walls that never maintain temperature, or high heating bills despite adequate attic insulation suggest empty or degraded wall cavities.
What it costs in Round Rock
Injection foam wall insulation in Round Rock typically runs $2,500-$5,500 for a standard single-story home, priced by linear foot of exterior wall and number of stories.
How we do it
We drill 5/8-inch holes through the exterior siding or interior drywall at stud-bay intervals, inject slow-rise foam that fills without bowing walls, then patch and match the surface finish.
Drill & Fill Wall Insulation
Signs you need it
Existing fiberglass batts that have settled to the bottom of the wall cavity, creating a 2-3 foot uninsulated zone at the top of exterior walls visible through thermal imaging.
What it costs in Round Rock
Drill and fill wall insulation in Round Rock generally ranges from $2,000-$4,500, depending on wall area, existing material removal needs, and access for drilling equipment.
How we do it
We remove minimal siding or drywall, extract settled material if present, blow dense-pack cellulose or fiberglass into each bay to the specified density, and restore the finish with matched materials.
What Wall Insulation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Injection foam wall insulation | $2,500 - $5,500 |
| Drill & fill wall insulation | $2,000 - $4,500 |
| Exterior wall insulation with interior access | $3,000 - $6,000 |
Will wall insulation damage my drywall or siding?
We minimize intrusion - injection foam uses holes under 1 inch that we patch and paint-match, and exterior drill access is restored with matched siding plugs so the work is nearly invisible after completion. Call (737) 252-7159 for a written scope showing exactly where we access.
How much does wall insulation help compared to attic work?
Attic upgrades typically deliver the highest ROI in Round Rock’s climate, but walls matter significantly for homes with empty cavities - we use thermal imaging during our energy audit to show you exactly where heat is moving so you can prioritize based on data.
Attic Cleaning & Rodent Proofing in Round Rock
Attic cleaning and rodent proofing in Round Rock is increasingly common as mature neighborhoods like Oak Creek develop tree-canopy corridors that roof rats use to access eave gaps left unsealed during original construction. The Dell-era build rush prioritized speed over pest exclusion, and we’ve found original builder gaps at fascia boards and vent screens in homes across Round Rock Glen and Old Round Rock. Attic Cleaning & Rodent Proofing always includes a documented photo record of entry points and the exclusion work completed.
Rodent Proofing & Exclusion
Signs you need it
Nocturnal scratching in ceilings, visible gnaw marks at roofline vents, or droppings in the attic indicate active rodent access that will continue until all entry points are sealed with rodent-proof materials.
What it costs in Round Rock
Rodent proofing and exclusion in Round Rock typically runs $800-$2,500, depending on the number of entry points, roof height, and whether soffit or fascia repair is needed.
How we do it
We inspect the roofline with ladders and cameras, seal all entry points with steel mesh and concrete patching where required, install vent guards, and provide a photo map of every location addressed.
Attic Sanitizing & Decontamination
Signs you need it
Ammonia odors detectable from the attic hatch, visible urine staining on insulation or decking, or confirmed rodent activity that has persisted for more than a few weeks requires enzyme treatment and surface sanitization.
What it costs in Round Rock
Attic sanitizing and decontamination in Round Rock generally ranges from $1,200-$3,000, including HEPA vacuuming, enzyme application, and antimicrobial treatment of all exposed surfaces.
How we do it
We remove contaminated insulation if present, HEPA-vacuum all surfaces, apply commercial-grade enzyme digesters that break down organic material, and fog antimicrobial protectant before any new insulation is installed.
What Attic Cleaning & Rodent Proofing Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Rodent proofing & exclusion | $800 - $2,500 |
| Attic sanitizing & decontamination | $1,200 - $3,000 |
| Full attic restoration (cleanout + proofing + re-insulation) | $3,500 - $8,000 |
How do rodents get into Round Rock attics?
They climb mature oak and pecan trees, traverse utility lines, and squeeze through gaps as small as 3/4 inch at fascia boards, roof vents, or unsealed eave returns - we document every access point with photos during our inspection. Call (737) 252-7159 for a free assessment.
Will rodent proofing keep them out permanently?
Our steel-mesh and concrete exclusion methods are designed to last the life of the structure, but we also identify environmental factors like overhanging branches that should be trimmed - the photo record shows you exactly what we sealed and what maintenance we recommend.
Home Energy Audit in Round Rock
Home energy audit in Round Rock is the diagnostic foundation for every insulation decision we make, particularly in the Dell-era housing stock where multiple systems - HVAC, ductwork, insulation, and air sealing - interact in ways that single-fix approaches miss. The February 2021 freeze and subsequent summer heat waves have made Round Rock homeowners acutely aware that their electric bills reflect envelope performance, not just equipment efficiency. Home Energy Audit work includes a written report with prioritized recommendations and the blower-door numbers that prove where your home is leaking.
Blower Door Test
Signs you need it
High electric bills with no equipment explanation, rooms that are consistently uncomfortable, or prior insulation work that didn’t deliver expected savings all warrant a pressurization test to quantify envelope leakage.
What it costs in Round Rock
A standalone blower door test in Round Rock typically runs $300-$600, or is included as part of a comprehensive energy audit scope.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure CFM50 - the cubic feet per minute of airflow required to maintain that pressure difference, which directly indicates total envelope leakage.
Thermal Imaging Inspection
Signs you need it
Visible temperature variations on walls or ceilings, ice dam history, or suspicion of missing insulation in specific wall cavities that standard visual inspection cannot confirm.
What it costs in Round Rock
Thermal imaging inspection in Round Rock generally ranges from $250-$500 as a standalone service, or is bundled with the full energy audit.
How we do it
We use FLIR infrared cameras during blower-door depressurization to visualize air leakage paths and insulation voids, capturing images that we annotate in your written report with specific locations and recommended actions.
What Home Energy Audit Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Blower door test (standalone) | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Comprehensive home energy audit | $400 - $900 |
What does a home energy audit include?
Our comprehensive audit includes blower-door testing, thermal imaging, insulation and ductwork inspection, combustion safety testing if gas appliances are present, and a written report with prioritized recommendations and estimated savings - all documented in your photo record. Call (737) 252-7159 to schedule.
How long does an energy audit take?
Most Round Rock single-family audits take 2.5 to 4 hours depending on home size and complexity; you receive the written report within 48 hours, and we review it with you line by line before any work is proposed.
