Insulation in Cedar Park, TX
Crawl space encapsulation and vapor barrier work in Cedar Park addresses a specific gap in our local housing stock: despite the city’s dominance of slab-on-grade construction, the master-planned communities and custom builds that do feature crawl spaces often suffer from Central Texas humidity and poor moisture management. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in, with written prices and documented blower-door results on every job. Call us at (737) 245-6428 for a free estimate with upfront pricing.
Why Cedar Park Homes Are Different
Cedar Park sits at the edge of the Balcones Escarpment, where prolonged summers push attic temperatures past 150°F and strain HVAC systems in homes that were built fast and insulated thin. The explosive growth from 2000 to 2015 produced thousands of production homes by KB Home, Meritage, and Lennar, most insulated to bare code minimums of R-22 to R-30. Those homes are now 10-20 years old, their insulation compacted and degraded, and many owners relocated from cooler climates for tech jobs are seeing $400-500 summer electric bills for the first time. The 2021 Winter Storm Uri also left lasting awareness that Texas homes built without margin can fail on both temperature extremes. The uniformity of builder-grade construction across neighborhoods like Twin Creeks and Forest Oaks means we see the same air leaks, the same top-plate gaps, and the same can-light bypasses from job to job. That predictability lets us scope accurately and stand behind our numbers.
Our Main Cedar Park Services
Most Cedar Park homeowners who call us start with attic work or spray foam, but we route every inquiry through the same assessment: seal first, then insulate.
Attic Insulation in Cedar Park
Attic insulation in Cedar Park typically means upgrading production-home attics from R-30 or below to R-38 to R-60, depending on the home’s geometry and HVAC load. We see the same pattern in Twin Creeks and Forest Oaks: compacted fiberglass, unsealed top plates, and can lights dumping conditioned air into 155°F attic space. Every attic job starts with a blower-door test to establish baseline leakage, followed by air sealing, then insulation. Attic Insulation in Cedar Park covers our full process and pricing.

Spray Foam Insulation in Cedar Park
Spray foam insulation in Cedar Park makes sense for specific applications: roof decks in homes with HVAC equipment in the attic, rim joists in the few homes with basements or crawl spaces, and select wall cavities in remodels. We use open-cell and closed-cell products from Icynene and Demilec, specified by application, not by brand loyalty. Cedar Park’s humidity and extreme attic temperatures mean vapor permeability calculations matter. Spray Foam Insulation in Cedar Park details when foam is the right choice versus blown-in.

Blown-In Insulation in Cedar Park
Blown-in insulation in Cedar Park is our most common attic upgrade, typically fiberglass from Owens Corning or Johns Manville or cellulose from GreenFiber, installed over a sealed attic floor to the depth required for target R-value. The material choice depends on attic conditions, existing insulation state, and homeowner preference; we stock all three and specify based on what we find during assessment. Blown-In Insulation in Cedar Park explains our material selection process and what the job looks like start to finish.

Crawl Space Encapsulation & Vapor Barrier in Cedar Park

While most Cedar Park homes are slab-on-grade, the master-planned communities and custom builds that do include crawl spaces face serious moisture challenges from Central Texas humidity and seasonal water table fluctuations. Crawl Space Encapsulation & Vapor Barrier is a service we perform selectively, where the building type justifies it, and always with the same documented approach: assess, seal, barrier, then verify. In Cedar Park’s clay-heavy soils, ground moisture migration into crawl spaces is predictable and preventable with proper encapsulation.
Crawl Space Vapor Barrier
Signs you need it
Standing water, efflorescence on block walls, or musty odors rising from floor registers indicate ground moisture is entering the crawl space and migrating upward.
What it costs in Cedar Park
A 6-mil to 20-mil vapor barrier installed over prepared ground in a typical Cedar Park crawl space runs $1,200 to $3,500 depending on square footage, pier count, and whether existing debris requires removal.
How we do it
We remove debris, grade the ground for drainage, seam-seal polyethylene sheeting at all overlaps, and seal the barrier to foundation walls with mechanical fasteners and compatible tape.
Crawl Space Encapsulation
Signs you need it
Chronic humidity above 70% RH, mold on floor joists, or fiberglass insulation falling from crawl space ceilings means the space is exchanging moist air with the exterior uncontrolled.
What it costs in Cedar Park
Full encapsulation with sealed vapor barrier, wall insulation, conditioned-air supply, and dehumidification in a Cedar Park crawl space typically ranges from $4,500 to $12,000 based on footprint and mechanical requirements.
How we do it
We install a sealed ground barrier, insulate and seal foundation walls, close vents, add a dedicated dehumidifier with condensate pump, and verify with humidity logging over 72 hours.
What Crawl Space Encapsulation & Vapor Barrier Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Crawl space vapor barrier (ground only) | $1,200 - $3,500 |
| Partial encapsulation (barrier + sealing) | $3,000 - $6,500 |
| Full encapsulation with dehumidification | $4,500 - $12,000 |
Do I need a vapor barrier if my crawl space has vents?
Vented crawl spaces in Cedar Park’s humid climate often make moisture problems worse by drawing in warm, wet air that condenses on cool surfaces. A sealed ground barrier plus vent sealing is usually more effective than ventilation alone.
How long does crawl space encapsulation take?
Most Cedar Park encapsulations finish in 2-4 days depending on debris removal needs and mechanical complexity; we provide a written schedule with the price before work starts.
Radiant Barrier Installation in Cedar Park

Cedar Park’s attic temperatures regularly hit 150-160°F in summer, turning unprotected roof decks into radiant heat sources that overwhelm HVAC systems even in well-insulated homes. Radiant Barrier Installation reduces radiant heat transfer from the roof deck to the attic floor and living space below, particularly effective in the production homes built during the 2003-2015 boom where roof ventilation was often minimal and insulation thin.
Attic Radiant Barrier
Signs you need it
Attic floor insulation that feels hot to the touch in summer, second rooms that stay 8-12°F warmer than the thermostat setting, or ductwork sweating in the attic all point to excessive radiant heat gain.
What it costs in Cedar Park
Radiant barrier installation across a typical 2,000-square-foot Cedar Park attic runs $1,500 to $3,200 for foil stapled to rafters or $2,800 to $5,500 for spray-applied radiant barrier coating.
How we do it
We install perforated aluminum foil across rafter bays with proper air gaps, or apply low-emissivity coating directly to roof decking, ensuring attic ventilation pathways remain unobstructed.
Radiant Barrier Roof Deck
Signs you need it
New roof installation or re-roofing presents the only practical opportunity to treat the roof deck itself with radiant barrier sheathing or coating.
What it costs in Cedar Park
Radiant barrier roof deck treatment during roof replacement in Cedar Park adds $1,200 to $2,800 to standard sheathing costs depending on roof pitch and square footage.
How we do it
We specify radiant barrier OSB or apply liquid radiant barrier coating to exposed deck before shingle installation, integrated with the roofing contractor’s schedule.
What Radiant Barrier Installation Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Foil radiant barrier (attic installation) | $1,500 - $3,200 |
| Spray-applied radiant barrier coating | $2,800 - $5,500 |
| Roof deck radiant barrier (during re-roof) | $1,200 - $2,800 |
Does radiant barrier work with existing insulation?
Radiant barrier complements rather than replaces insulation; in Cedar Park attics we typically install it over sealed air leaks and existing or new blown-in insulation for combined conductive and radiant heat control.
Will radiant barrier help my AC keep up in August?
A properly installed radiant barrier can reduce attic heat gain by 20-35%, which directly reduces the load on your AC during Cedar Park’s hottest weeks; we measure the before-and-after effect with attic temperature logging.
Insulation Removal & Replacement in Cedar Park

The production homes built during Cedar Park’s 2000-2015 growth spurt are now reaching the age where original insulation has compacted, settled below joist tops, or been compromised by rodent activity and moisture. Insulation Removal & Replacement is often the right starting point for homeowners who want to address energy bills and indoor air quality simultaneously, particularly in neighborhoods where builder-grade fiberglass was installed to minimum code and never upgraded.
Contaminated Insulation Removal
Signs you need it
Insulation with visible rodent droppings, urine staining, mold growth, or saturated areas from past roof leaks cannot be effectively treated in place and must be removed.
What it costs in Cedar Park
Contaminated insulation removal in a typical Cedar Park attic runs $1,800 to $4,500 including HEPA-contained extraction, bagging, and proper disposal, before replacement insulation is priced.
How we do it
We set up negative air containment, remove contaminated material with HEPA-filtered vacuums, treat exposed surfaces with antimicrobial where indicated, and document with photos before installing new insulation.
Insulation Replacement
Signs you need it
Insulation settled below the top of joists, with visible gaps around perimeters and fixtures, or R-values degraded by age and compression to below R-20 in a Cedar Park attic.
What it costs in Cedar Park
Full insulation replacement with air sealing and new blown-in fiberglass or cellulose to R-38 in a typical Cedar Park home ranges from $3,500 to $7,500 depending on attic square footage and accessibility.
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 specified depth with depth markers every 300 square feet.
What Insulation Removal & Replacement Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Contaminated insulation removal only | $1,800 - $4,500 |
| Standard removal + replacement to R-38 | $3,500 - $7,500 |
| Removal + replacement with full air sealing | $5,000 - $9,500 |
Can you remove insulation without tearing out my ceiling?
Yes, we access the attic through the hatch and remove material from above; the ceiling drywall stays intact, though we do need clear attic access and may enlarge the hatch if it’s undersized.
How do I know if my insulation is contaminated or just old?
We inspect during our free estimate and show you photos; if you see droppings, dark staining, or smell ammonia when the HVAC runs, assume contamination and call (737) 245-6428 for assessment.
Attic Air Sealing in Cedar Park

Cedar Park’s production homes from the 2003-2015 building boom share a predictable pattern of air leakage: unsealed top plates where interior walls meet the attic, can lights and duct boots creating direct paths to conditioned space, and attic hatches that leak like open windows. Attic Air Sealing is the foundation of every insulation job we do, and we publish before-and-after blower-door numbers so homeowners can verify the performance change they paid for.
Top Plate & Penetration Sealing
Signs you need it
Dust streaks around ceiling fixtures, rooms that are hard to keep at temperature, or blower-door tests showing excessive leakage at the attic floor indicate unsealed top plates and wire/plumbing penetrations.
What it costs in Cedar Park
Top plate and penetration sealing in a typical Cedar Park production home runs $800 to $2,200 as a standalone service, or is included as the first phase of any full attic insulation upgrade.
How we do it
We locate all top plates and penetrations with blower-door-directed diagnostics, seal gaps with expanding foam and fire-rated caulk as appropriate, and verify with post-sealing blower-door test.
Can Light & Duct Boot Sealing
Signs you need it
Can lights that are hot in summer or cold in winter, or duct boots with visible gaps to attic space, create continuous air bypasses that undermine insulation performance.
What it costs in Cedar Park
Sealing can lights with proper covers and duct boots with mastic and metal tape in a typical Cedar Park attic adds $600 to $1,800 to the air sealing scope depending on fixture count.
How we do it
We install fire-rated airtight covers over can lights, seal duct boots with UL-181 mastic and reinforced tape, and confirm no leakage remains with blower-door and smoke pencil verification.
What Attic Air Sealing Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Basic attic air sealing (top plates, penetrations) | $800 - $2,200 |
| Comprehensive sealing with can lights and duct boots | $1,400 - $4,000 |
| Air sealing + blower-door testing (before/after) | $1,800 - $4,500 |
Do I need air sealing if I’m adding more insulation?
Yes, blowing new insulation over unsealed leaks is like adding a thicker blanket over a window you left open; we seal first, insulate second, and document the blower-door improvement on every job.
What does a blower-door test tell me?
A blower-door test pressurizes or depressurizes your home to measure total air leakage in CFM50 - a single number showing how much conditioned air escapes; we provide the before and after readings in writing.
Wall Insulation in Cedar Park

Cedar Park’s slab-on-grade production homes built between 2003 and 2015 typically have 2×4 exterior walls insulated with R-13 fiberglass batts that are poorly fitted, compressed, or missing entirely behind electrical boxes and plumbing stacks. Wall Insulation upgrades in these homes require specialized injection or drill-and-fill techniques that don’t require interior demolition, making them practical for homeowners who want better envelope performance without gutting finished rooms.
Injection Foam Wall Insulation
Signs you need it
Walls that are cold to the touch in winter, rooms with significant temperature variation from exterior walls, or energy audits showing high conductive loss through the building envelope.
What it costs in Cedar Park
Injection foam wall insulation for a typical 2,000-square-foot Cedar Park home with accessible stud cavities runs $3,500 to $8,000 depending on wall area, cavity condition, and foam density specified.
How we do it
We drill 5/8-inch holes through exterior siding or interior drywall at stud-bay intervals, inject slow-rise foam to fill cavities completely, and patch holes to match existing finish.
Drill & Fill Wall Insulation
Signs you need it
Existing fiberglass batts that have settled, been removed by prior contractors, or never fully filled the cavity, leaving cold spots and air channels in exterior walls.
What it costs in Cedar Park
Drill-and-fill with dense-pack cellulose or fiberglass in a typical Cedar Park home runs $2,800 to $6,500, with exterior access preferred to avoid interior patching.
How we do it
We access wall cavities through strategic exterior or interior holes, dense-pack cellulose or fiberglass to specified density with continuous fill verification, and seal all penetrations airtight.
What Wall Insulation Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Drill-and-fill with dense-pack cellulose | $2,800 - $6,500 |
| Injection foam (slow-rise, open-cell) | $3,500 - $8,000 |
| Exterior wall insulation with air sealing | $4,500 - $10,000 |
Will drill-and-fill damage my walls or siding?
We drill through exterior siding where possible and patch with matching materials; interior work requires drywall patching that we include in the scope and price upfront.
How much does wall insulation help compared to attic work?
In Cedar Park’s climate, attic upgrades typically yield the highest return, but walls matter significantly for homes with R-13 or empty cavities; our energy audit shows the relative contribution of each envelope component.
Attic Cleaning & Rodent Proofing in Cedar Park

Cedar Park’s mature neighborhoods with established tree canopy and proximity to greenbelts create conditions where roof rats and squirrels regularly access attics through construction gaps, vent screens, and fascia rot. Attic Cleaning & Rodent Proofing addresses both the immediate contamination and the entry points that allow recurrence, which we see repeatedly in 10-20-year-old homes where original builder flashing and vents have degraded.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in walls or ceiling at dawn and dusk, gnawed vent screens, droppings in the attic, or visible rub marks along fascia and soffits indicate active rodent access.
What it costs in Cedar Park
Rodent proofing and exclusion for a typical Cedar Park home runs $1,200 to $3,500 including entry point sealing, vent screening, and one-way door installation where active infestation exists.
How we do it
We inspect the roofline, soffits, vents, and foundation with the homeowner present, seal all entry points with rodent-proof materials, install heavy-gauge vent screens, and provide photo documentation of every location addressed.
Attic Sanitizing & Decontamination
Signs you need it
Visible rodent droppings, urine staining on insulation or decking, or persistent odor from the attic space after exclusion work indicates biological contamination requiring treatment.
What it costs in Cedar Park
Attic sanitizing and decontamination following rodent activity in a typical Cedar Park attic runs $1,500 to $4,000 including HEPA vacuuming, enzyme treatment, and antimicrobial application where indicated.
How we do it
We remove contaminated insulation if necessary, HEPA-vacuum all surfaces, apply enzyme digester to break down organic material, treat with EPA-registered antimicrobial, and verify with ATP testing before reinstalling insulation.
What Attic Cleaning & Rodent Proofing Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Rodent proofing and exclusion only | $1,200 - $3,500 |
| Attic sanitizing and decontamination | $1,500 - $4,000 |
| Full cleanup, proofing, and insulation replacement | $4,500 - $11,000 |
How do rodents get into Cedar Park attics?
Roof rats are excellent climbers and exploit gaps as small as half an inch at roof intersections, loose vent screens, and deteriorated fascia; we find the access points during inspection and seal them with materials rodents can’t chew.
Do you handle the rodents or just seal the house?
We focus on exclusion and decontamination; for active infestations we coordinate with licensed pest control for trapping and removal, then seal entry points to prevent re-infestation.
Home Energy Audit in Cedar Park

Cedar Park’s tech-savvy homeowner demographic, many relocated from cooler climates with lower energy costs, responds strongly to data-driven proposals that quantify exactly where their home is losing conditioned air. Home Energy Audit provides the documentation these homeowners want: blower-door numbers, thermal images, and prioritized recommendations with expected savings, all delivered in a written report before any work is discussed.
Blower Door Test
Signs you need it
High energy bills with no obvious cause, rooms that won’t maintain temperature, or prior insulation work that didn’t produce expected savings suggest hidden air leakage that a blower-door test will quantify.
What it costs in Cedar Park
A standalone blower-door test with written report in Cedar Park runs $300 to $600; when bundled with thermal imaging and full audit, it’s typically credited toward subsequent work.
How we do it
We install a calibrated fan in an exterior door, depressurize the home to 50 Pascals, measure airflow in CFM50, and use smoke pencils and infrared cameras to locate leakage paths while the house is under test.
Thermal Imaging Inspection
Signs you need it
Uneven wall or ceiling temperatures visible as cold spots in winter or hot spots in summer, or suspicion of missing insulation in specific wall cavities or attic areas.
What it costs in Cedar Park
Thermal imaging inspection as part of a full energy audit runs $150 to $400 as a standalone add-on, or included in comprehensive audit packages from $450 to $900.
How we do it
We scan all exterior walls, ceilings, and accessible floor areas with a calibrated FLIR camera during blower-door testing to identify insulation voids, air leaks, and thermal bridges, then annotate images in the written report.
What Home Energy Audit Costs in Cedar Park
| Item | Typical range in Cedar Park |
|---|---|
| Blower-door test with written report | $300 - $600 |
| Thermal imaging inspection | $150 - $400 |
| Comprehensive home energy audit | $450 - $900 |
What do I get after a home energy audit?
You receive a written report with blower-door before-and-after projections, annotated thermal images, prioritized recommendations with cost estimates, and expected savings; we also provide the documented photo record of our findings.
Is an energy audit worth it before insulating?
Yes, particularly in Cedar Park’s uniform production housing where we can predict common deficiencies; the audit prevents spending on insulation where air sealing would yield more impact, and the audit fee credits toward work you approve.

What Cedar Park Customers Say
"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E."They air-sealed the attic floor before insulating and showed me the blower-door number before and after. The upstairs is finally the same temperature as downstairs."
- Marisol D."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R.
