Insulation in Cedar Park, TX
Crawl space encapsulation and vapor barrier installation in Cedar Park typically runs $3,500-$7,500 for homes in the area’s master-planned communities, with most jobs completed in two days. The combination of clay-heavy soils, seasonal humidity swings, and the region’s 1999-2018 production housing stock means Cedar Park crawl spaces face moisture problems that slab-on-grade construction elsewhere often avoids. We dispatch crews from our Austin office and carry vapor barrier materials sized for the 1,200-2,800 square foot footprints common in neighborhoods like Twin Creeks and Buttercup Creek. Call (737) 259-8352 for a written price before any work starts.
Why Cedar Park Homes Are Different
Cedar Park’s transformation from a small town to one of America’s fastest-growing cities between roughly 2000 and 2018 produced a massive, uniform wave of builder-grade tract homes. Most were installed with minimum-code R-30 blown-in fiberglass attic insulation that has now settled and compacted over 15-20 years of brutal thermal cycling. This concentrated aging stock, all hitting the same maintenance window simultaneously, makes attic top-offs and comprehensive air sealing the defining insulation job in Cedar Park in a way that distinguishes it from older, more varied Austin neighborhoods just to the south.
The dominant housing stock is two-story production homes built 1999-2018 by large-volume builders like DR Horton, Centex, and Meritage, typically on slab foundations with 2×4 or 2×6 framing. After repeated extreme heat cycles, original R-30 installations frequently test out at effective R-22 or lower due to settling and air infiltration at penetrations. In the large two-story homes throughout Twin Creeks and Buttercup Creek, HVAC supply ducts often run through unconditioned attic space, meaning settled insulation doesn’t just overheat the second floor; it directly degrades duct efficiency. Cedar Park falls in IECC Climate Zone 2, where attics reach 140-160°F in summer, and the February 2021 Winter Storm Uri revealed how badly most tract homes are air-sealed against cold.
Our Main Cedar Park Services
Most Cedar Park homeowners who call us start with one of these three services, each with its own dedicated page for deeper detail.
Attic Insulation in Cedar Park
Attic insulation in Cedar Park is almost always a top-off or full replacement of settled blown-in fiberglass in production homes built 1999-2018. We test effective R-value before quoting, not after, because visual inspection can’t distinguish R-30 from R-22 once settling has occurred. Our crews air seal before insulating, every time, and publish before-and-after blower-door numbers so you can verify the performance change. Attic Insulation in Cedar Park covers material options, pricing, and what the documentation looks like when we finish.
Spray Foam Insulation in Cedar Park
Spray foam insulation in Cedar Park makes the most sense for bonus rooms over garages, sealed attics, and rim-joist work in homes with conditioned crawl spaces. We use open-cell and closed-cell products from Icynene and Demilec, selected by application, not by brand exclusivity. Every spray foam job gets a written scope specifying thickness, density, and coverage area before the rig arrives. Spray Foam Insulation in Cedar Park has the full breakdown of when foam beats fiberglass and what it costs.
Blown-In Insulation in Cedar Park
Blown-in insulation in Cedar Park is the workhorse solution for the thousands of homes with compacted original fiberglass in their attics. We blow Rockwool or CertainTeed fiberglass to specified depth and density, measured with a ruler in multiple locations, not estimated from the hopper load. The job includes air sealing of top plates, can lights, and duct boots before the blower runs. Blown-In Insulation in Cedar Park explains our density targets and how we document them.

Before
AfterCrawl Space Encapsulation & Vapor Barrier in Cedar Park
Crawl space encapsulation and vapor barrier installation in Cedar Park addresses a specific problem: the minority of homes here with pier-and-beam or partial-crawl construction, often in older pockets and infill lots, face moisture intrusion from clay soils that expand in wet seasons and shrink in drought. Unlike the slab-on-grade majority, these homes need active moisture control at the ground plane to prevent mold, wood rot, and subfloor damage. We install Crawl Space Encapsulation & Vapor Barrier systems that include sealed vapor barriers, dehumidification where needed, and insulation at the foundation walls rather than the floor, because insulating the floor in a vented crawl space is obsolete practice in Climate Zone 2.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on block walls, or a musty smell that enters the living space through floor gaps.
What it costs in Cedar Park
A 6-mil to 20-mil vapor barrier installation for a typical Cedar Park crawl space runs $1,500-$3,500, with thicker reinforced polyethylene and full seam sealing at the higher end.
How we do it
We remove debris, grade the soil surface, lay overlapping sheets of reinforced polyethylene, seal all seams with pressure-sensitive tape, and extend the barrier 6-12 inches up foundation walls before mechanical fastening.
Crawl Space Encapsulation
Signs you need it
Your crawl space has chronic humidity above 70 percent, visible mold on joists or subfloor, or your hardwood floors cup seasonally from below.
What it costs in Cedar Park
Full encapsulation with sealed vapor barrier, wall insulation, and dehumidifier for a Cedar Park crawl space typically runs $4,000-$8,500 depending on square footage and existing damage.
How we do it
We seal all vents, install a continuous reinforced vapor barrier across floor and walls, insulate foundation walls with rigid foam, add a condensate-pumped dehumidifier, and provide before-and-after humidity readings.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Vapor barrier (6-20 mil, floor only) | $1,500 - $3,500 |
| Full encapsulation with dehumidifier | $4,000 - $8,500 |
| Crawl space insulation (rigid foam walls) | $2,000 - $4,500 |
Do I need a dehumidifier with encapsulation in Cedar Park?
Yes, in most cases. Cedar Park’s clay soils and seasonal humidity mean a sealed crawl space without active dehumidification can trap moisture against wood framing. We size the dehumidifier to the crawl space volume and include a drain line to the exterior or a condensate pump.
How long does crawl space encapsulation take in Cedar Park?
Most Cedar Park crawl space encapsulations finish in two to three days. Larger footprints or jobs requiring mold remediation first may extend to four days. We provide a written schedule with the price before starting.
Radiant Barrier Installation in Cedar Park
Radiant barrier installation in Cedar Park is one of the highest-ROI envelope upgrades for the city’s production-home stock, because attics here routinely hit 140-160°F and most homes have dark shingle roofs with minimal natural shading. A properly installed radiant barrier can reduce attic air temperature by 20-35°F, which directly lowers the cooling load on ductwork running through unconditioned space. We install Radiant Barrier Installation systems that are measured, not estimated, with documented coverage percentages in your photo record.
Attic Radiant Barrier
Signs you need it
Your second floor stays 8-12°F hotter than the first despite adequate insulation depth, or your AC runs continuously on summer afternoons without reaching setpoint.
What it costs in Cedar Park
Radiant barrier installation for a typical Cedar Park attic runs $1,200-$2,800, with price driven by attic square footage, roof pitch, and whether we staple to rafters or lay over existing insulation.
How we do it
We measure attic dimensions, calculate coverage area, install perforated foil or reflective sheeting to underside of rafters with proper air gap, and photograph coverage percentage for your record.
Radiant Barrier & Ventilation
Signs you need it
Your attic has radiant barrier but still overheats, or you have blocked soffit vents, inadequate ridge venting, or a powered attic ventilator that pulls conditioned air upward.
What it costs in Cedar Park
Radiant barrier with ventilation correction in Cedar Park typically runs $1,800-$3,500, including baffle installation, vent clearing, or ridge vent upgrade as needed.
How we do it
We inspect intake and exhaust ventilation paths, install baffles to maintain soffit airflow over insulation, correct any exhaust vent blockage, then install radiant barrier with documented coverage.
What Radiant Barrier Installation Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Attic radiant barrier (rafter staple) | $1,200 - $2,800 |
| Radiant barrier with ventilation correction | $1,800 - $3,500 |
| Radiant barrier roof deck (new construction or re-roof) | $2,500 - $4,500 |
Does radiant barrier work with settled insulation in Cedar Park?
It helps, but it’s not a substitute for proper R-value. We test your existing insulation first; if it’s compacted to R-22 or below, we quote air sealing, insulation top-off, and radiant barrier together so you’re not treating a symptom while ignoring the cause.
Can radiant barrier be installed in summer?
Yes, though we schedule early morning starts in July and August when attic temperatures peak. Our crews use hydration protocols and work in pairs for safety in extreme heat. The job itself takes four to six hours for most Cedar Park attics.
Insulation Removal & Replacement in Cedar Park
Insulation removal and replacement in Cedar Park is most common in homes where the original blown-in fiberglass has been compromised by rodent activity, water damage, or simple age-related degradation beyond what a top-off can fix. The 1999-2018 production stock here often has insulation that was installed to minimum code and has never been inspected; after 15-20 years, we find significant contamination or settling that makes removal the only honest recommendation. We handle Insulation Removal & Replacement with HEPA-contained extraction, so fibers and waste don’t enter your living space.
Contaminated Insulation Removal
Signs you need it
Your attic insulation has visible rodent droppings, urine staining, mold growth, or a persistent odor that enters the house through recessed lights and ceiling penetrations.
What it costs in Cedar Park
Contaminated insulation removal for a typical Cedar Park attic runs $1,500-$3,500, with price varying by contamination extent, accessibility, and whether hazmat protocols apply.
How we do it
We set up HEPA-contained negative-air extraction, remove all compromised material to bagged waste containers, apply antimicrobial treatment to exposed decking, and document the empty cavity before replacement.
Insulation Replacement
Signs you need it
Your attic has been stripped to joists, your original insulation was removed by a prior contractor, or testing shows effective R-value below R-19 with no recoverable material.
What it costs in Cedar Park
Full insulation replacement in Cedar Park typically runs $2,500-$5,500 including air sealing, with final price set by attic square footage, target R-value, and material selected.
How we do it
We air seal all top plates, penetrations, and duct boots first, then install blown-in fiberglass or Rockwool to specified depth and density, measuring with a ruler in ten or more locations for your record.
What Insulation Removal & Replacement Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Contaminated insulation removal | $1,500 - $3,500 |
| Insulation replacement (with air sealing) | $2,500 - $5,500 |
| Vermiculite or old insulation removal | $3,000 - $6,500 |
How do I know if my insulation needs removal or just a top-off?
We test with a ruler and visual inspection. If we find rodent contamination, water damage, or settling below 50 percent of original depth, removal is the only option. For uniform settling with clean material, a top-off with air sealing is usually sufficient and costs less.
Is insulation removal messy for the rest of the house?
Not when done correctly. Our extraction runs through HEPA filtration with negative air pressure in the attic; no debris enters your living space. We seal the attic hatch during work and clean the access path when finished. Your photo record shows the containment setup.
Attic Air Sealing in Cedar Park
Attic air sealing in Cedar Park is the single most overlooked upgrade in the city’s production housing stock, because builders in the 1999-2018 wave prioritized speed over envelope tightness and code enforcement on air sealing was minimal. The February 2021 Winter Storm Uri exposed how much conditioned air these homes lose through top plates, can lights, and attic hatches; we now treat air sealing as a standalone service for homeowners who want to fix leaks before adding insulation. Our Attic Air Sealing work is always measured with a blower-door test so you can see the CFM50 reduction in writing.
Top Plate & Penetration Sealing
Signs you need it
Your blower-door test shows excessive air leakage, you feel drafts at outlets on exterior walls, or your energy bills spike in both summer and winter despite adequate insulation depth.
What it costs in Cedar Park
Top plate and penetration sealing for a typical Cedar Park two-story home runs $800-$1,800, with price set by linear feet of top plate, number of penetrations, and attic accessibility.
How we do it
We locate all top plates, wire penetrations, and plumbing stacks with blower-door-guided smoke testing, seal with fire-rated caulk and expanding foam, and retest to document CFM50 reduction.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights are not IC-rated airtight housings, your duct boots show dust streaking from air leakage, or rooms farthest from the air handler never reach setpoint.
What it costs in Cedar Park
Can light and duct boot sealing in Cedar Park typically runs $400-$1,200 depending on fixture count, duct configuration, and whether we install airtight covers or seal from the attic side.
How we do it
We cover non-IC can lights with fire-rated airtight boxes from the attic, seal duct boots with mastic and mesh, pressure-test the duct system where accessible, and photograph each sealed location.
What Attic Air Sealing Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Top plate & penetration sealing | $800 - $1,800 |
| Can light & duct boot sealing | $400 - $1,200 |
| Full attic air sealing (comprehensive) | $1,500 - $3,000 |
Can air sealing alone lower my energy bills in Cedar Park?
Yes, though it’s most effective paired with proper insulation. We’ve measured 15-30 percent CFM50 reductions from air sealing alone in Cedar Park tract homes, which translates to measurable cooling load reduction when ducts run through the attic. We quote both options so you can choose.
How long does attic air sealing take?
Most Cedar Park attic air sealing jobs finish in one day. Two-story homes with complex duct routing or extensive can light counts may extend to a second day. We provide the schedule with your written price before starting.
Wall Insulation in Cedar Park
Unlike attic insulation, wall insulation can’t be visually inspected without invasive work, so we use infrared imaging during our energy audits to identify voids before recommending a solution. Our Wall Insulation page details the injection and drill-and-fill methods we use to upgrade walls without tearing out drywall.
Injection Foam Wall Insulation
Signs you need it
Your exterior walls feel hot to the touch in summer, your energy audit shows more than 5°F temperature differential on exterior walls, or you have rooms that never maintain setpoint despite good attic insulation.
What it costs in Cedar Park
Injection foam wall insulation for a typical Cedar Park two-story home runs $3,500-$7,500, with price driven by wall square footage, cavity condition, and whether we access from interior or exterior.
How we do it
We drill 5/8-inch holes at stud-bay intervals, inject slow-rise foam to fill voids without bowing drywall, plug holes with matching material, and verify fill with thermal imaging from both sides.
Drill & Fill Wall Insulation
Signs you need it
Your walls have no insulation, contain degraded batts from water damage, or were built with empty cavities in garage-adjacent or porch-roof areas common in Cedar Park’s builder shortcuts.
What it costs in Cedar Park
Drill and fill with dense-pack fiberglass or cellulose in Cedar Park typically runs $2,500-$5,500 for a complete home, with partial-area jobs priced by linear wall foot.
How we do it
We remove exterior siding or drill through drywall at the top of each bay, blow material to calculated density with hose pressure monitoring, verify fill with resistance testing, and restore all surfaces.
What Wall Insulation Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Injection foam (full home) | $3,500 - $7,500 |
| Drill & fill (dense-pack) | $2,500 - $5,500 |
| Exterior wall insulation (partial, garage/porch areas) | $800 - $2,000 |
Will injection foam damage my walls?
No, when properly installed. We use slow-rise formulations at controlled pressure, drill at stud-bay centers, and verify no bowing with laser level before closing holes. In 9,000-plus jobs since 2016, we’ve had zero drywall failures from foam injection.
Can you insulate walls without removing drywall?
Usually yes. We access most wall cavities by drilling through exterior siding or at the top plate from the attic, then restore surfaces to match. Interior access is only needed for specific wall sections with no exterior exposure.
Attic Cleaning & Rodent Proofing in Cedar Park
Attic cleaning and rodent proofing in Cedar Park is increasingly common as the city’s mature neighborhoods develop tree canopy and wildlife pressure from the Balcones Canyonlands Preserve interface. Roof rats and squirrels exploit construction gaps in 1999-2018 production homes that were never sealed to pest-resistant standards, contaminating insulation and creating fire hazards from chewed wiring. We provide Attic Cleaning & Rodent Proofing as a documented service with photo evidence of entry points sealed and contamination removed.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching in walls or ceilings at night, find droppings in the attic, or see chew marks on fascia boards, roof vents, or garage door seals.
What it costs in Cedar Park
Rodent proofing and exclusion for a typical Cedar Park home runs $800-$2,000, with price varying by entry point count, roof complexity, and whether one-way doors are needed for active eviction.
How we do it
We inspect roofline, soffits, vents, and foundation with photo documentation, seal all entry points larger than 1/4 inch with rodent-resistant materials, install one-way doors where needed, and provide a written exclusion map.
Attic Sanitizing & Decontamination
Signs you need it
Your attic has visible rodent droppings, urine staining on insulation or decking, or a persistent ammonia odor that enters living spaces through ceiling penetrations.
What it costs in Cedar Park
Attic sanitizing and decontamination in Cedar Park typically runs $1,200-$2,800 depending on contamination extent, attic square footage, and whether insulation removal precedes treatment.
How we do it
We remove contaminated insulation with HEPA-contained extraction, apply enzyme-based sanitizer to all exposed surfaces, treat with odor-neutralizing agent, and verify with ATP testing before installing new insulation.
What Attic Cleaning & Rodent Proofing Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Rodent proofing & exclusion | $800 - $2,000 |
| Attic sanitizing & decontamination | $1,200 - $2,800 |
| Full attic restoration (removal, sanitize, re-insulate) | $3,500 - $7,500 |
How do I know rodents are gone before you re-insulate?
We install one-way doors at primary entry points and monitor for activity for 5-7 days before scheduling insulation work. Your photo record shows sealed entries and the monitoring period. We don’t install new insulation over active infestation.
Is rodent damage covered by homeowners insurance in Cedar Park?
Rarely for the rodent work itself, though some policies cover chewed wiring or water damage from entry gaps. We document all damage with photos for your claim and provide a written scope of repair work separate from exclusion pricing.
Home Energy Audit in Cedar Park
A home energy audit in Cedar Park is the starting point for homeowners who want data before spending money, especially in the city’s production housing stock where problems are often layered and interdependent. Our audits identify whether your high bills come from duct leakage, envelope infiltration, inadequate insulation, or all three, so you’re not treating a symptom while missing the cause. We perform Home Energy Audit work to BPI or RESNET standards, with every test documented and every recommendation prioritized by cost-effectiveness.
Blower Door Test
Signs you need it
Your energy bills are 30 percent or more above neighbors with similar homes, you feel persistent drafts, or you’re considering insulation upgrades and want to measure air leakage first.
What it costs in Cedar Park
A standalone blower-door test in Cedar Park runs $250-$450, or it’s included at no additional charge when bundled with a full energy audit or insulation proposal.
How we do it
We install a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 airflow, and use smoke pencils and infrared cameras to locate leakage paths while the fan runs.
Thermal Imaging Inspection
Signs you need it
You have rooms that never reach temperature, suspect missing wall insulation, or want to verify insulation coverage before quoting an upgrade.
What it costs in Cedar Park
Thermal imaging inspection in Cedar Park typically runs $200-$400 as a standalone service, or included within a full energy audit at $400-$650 total.
How we do it
We scan all exterior walls, ceilings, and foundation areas with a calibrated infrared camera during controlled temperature differential conditions, mark anomalies on floor plans, and provide images with temperature readings.
What Home Energy Audit Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Blower-door test (standalone) | $250 - $450 |
| Thermal imaging inspection | $200 - $400 |
| Full home energy audit (comprehensive) | $400 - $650 |
What does a home energy audit include in Cedar Park?
A full audit includes blower-door test, thermal imaging, insulation inspection, duct leakage test where accessible, and a written report with prioritized recommendations and estimated savings. We schedule 3-4 hours on site and deliver the report within 48 hours.
Should I get an audit before or after buying a home in Cedar Park?
Before closing, if possible. We’ve audited many Cedar Park homes where buyers discovered $3,000-$8,000 in envelope repairs after purchase; a pre-closing audit gives you leverage in negotiation and a repair priority list for your first year.
