Attic Insulation in Kyle - Same-Day Service, Done Right the First Time

Insulation in Kyle, TX

Crawl space encapsulation and vapor barrier work in Kyle, TX typically runs $3,500-$8,500 for full encapsulation and $1,200-$2,800 for vapor barrier-only jobs, with most projects completed in one to two days. We’re Envelope Insulation Co., and we treat air sealing as a hard prerequisite before any insulation goes in - not an upsell. In Kyle’s fast-growing subdivisions off Kyle Parkway and Yarrington Road, production-built homes were thrown up at speed with minimum-code insulation and little attention to the crawl space, leaving thousands of homeowners with moisture problems they didn’t discover until the first humid summer or the February 2021 freeze.

Why Kyle Homes Are Different

Kyle has been one of the fastest-growing cities in the United States for over a decade, and that growth created a housing stock built for speed, not performance. The vast majority of homes in the 78610 and 78640 ZIP codes are production-built tract homes from national volume builders targeting Austin commuters on I-35 - homes that routinely received R-30 batts in attics rated for R-38, compressed insulation over top plates, and dozens of air gaps around recessed lighting and HVAC boots.

This isn’t a knock on any one builder; it’s the economics of hitting entry-level price points in a fast-flipping commuter market. The result: thousands of “brand-new” homes that are chronically under-insulated for Central Texas’s 100°F+ summers, with crawl spaces that vent humid outside air directly beneath the floor system and attics that hit 150°F while the AC runs nonstop. Out-of-state buyers often don’t realize the problem until their first July electric bill arrives. The small core of pre-boom homes near Kyle Parkway and the historic district around the Kyle Family Pioneer Cemetery present the opposite problem - older, unimproved construction with even weaker thermal envelopes and no air sealing at all.

Climate Zone 2 means the cooling season stretches from April through October, and the February 2021 storm proved that minimum-code insulation fails catastrophically when temperatures drop into single digits. Many Kyle homes still haven’t been retrofitted. We dispatch crews from our Austin office and serve Kyle locally, with response times that typically put us on Camino Real or South FM 1626 within the same day.

Our Main Kyle Services

Most Kyle homeowners who call us start with one of these three services:

Attic Insulation in Kyle

Attic insulation in Kyle means dealing with 150°F summer attic temperatures and production-built homes where the original R-30 batts were compressed, gapped, or installed short of the rated R-value. We start every attic job with a blower-door test to measure air leakage, then seal top plates, can lights, and duct boots before adding any new material. The homeowner gets before-and-after pressurization numbers and a Documented Photo Record showing exactly what was sealed and where. Attic Insulation in Kyle covers our full process, material options from Owens Corning to Rockwool, and what the written price includes.

Spray Foam Insulation in Kyle

Spray foam insulation in Kyle makes sense for homeowners who want to convert an attic to conditioned space, seal a vented crawl space, or address the chronic air leakage in post-2015 subdivisions where fiberglass batts left gaps at every penetration. We use open-cell and closed-cell products from Icynene and Demilec, specified by application - never a one-product-fits-all approach. Every spray foam job gets a written scope, written warranty, and post-installation blower-door verification. Spray Foam Insulation in Kyle breaks down open-cell versus closed-cell costs and where each performs best in Kyle’s climate.

Blown-In Insulation in Kyle

Blown-in insulation in Kyle is the most common retrofit for production-built homes that need more R-value without tearing into finished walls. We blow fiberglass or cellulose over sealed attic floors after completing air sealing of top plates, can lights, and penetrations - never over an unsealed attic, per our hard rule. The material levels out over existing framing, fills odd cavities that batts miss, and typically brings a Kyle attic from R-30 to R-38 or R-49 in a single day. Blown-In Insulation in Kyle has pricing, material comparisons, and what the written scope covers.

Crawl Space Encapsulation & Vapor Barrier in Kyle

Kyle’s crawl spaces are a direct product of its building boom: volume builders prioritized slab-on-grade construction where possible, but many homes on the east side of town and in older subdivisions off Camino Real still have vented crawl spaces that pull humid Central Texas air beneath the floor system. In summer, that means 70%+ relative humidity under the house, condensation on ductwork, and the musty smell that creeps up through floor registers. In winter, the same vented crawl space lets cold air wash across plumbing and HVAC lines. Crawl Space Encapsulation & Vapor Barrier is our primary service for Kyle homeowners dealing with moisture, odor, or temperature stratification between rooms.

Crawl Space Encapsulation

Signs you need it

Your floors feel cold in winter despite the heat running, you smell mustiness near floor registers, or you’ve found mold on floor joists or insulation falling from the subfloor.

What it costs in Kyle

Full crawl space encapsulation in Kyle typically runs $3,500-$8,500 depending on square footage, existing moisture damage, and whether we need to install a sump pump or dehumidifier.

How we do it

We remove degraded insulation, grade the floor, install a reinforced vapor barrier across the entire ground surface and up the walls, seal all seams and piers, close the vents, and condition the space with a dehumidifier tied to a dedicated drain.

Crawl Space Vapor Barrier

Signs you need it

The ground in your crawl space is bare soil or thin plastic, you see standing water after rain, or your HVAC ducts sweat in summer months.

What it costs in Kyle

Vapor barrier-only installation in Kyle typically runs $1,200-$2,800 for standard crawl spaces under 1,500 square feet, with thicker reinforced barriers at the higher end.

How we do it

We clear debris, lay a 6-mil or thicker reinforced polyethylene barrier across the entire ground surface, overlap and tape all seams, and seal around piers and foundation walls to block soil moisture migration.

What Crawl Space Encapsulation & Vapor Barrier Costs in Kyle

How long does crawl space encapsulation take in Kyle?

Most Kyle encapsulation jobs finish in one to two days; larger crawl spaces or those requiring mold remediation, structural repairs, or sump pump installation may extend to three days. We provide a written schedule with the written price before any work starts.

Will encapsulation help my electric bill in Kyle?

Yes - sealing the crawl space stops conditioned air loss through the floor and reduces humidity load on your HVAC system, which in Kyle’s Climate Zone 2 cooling season can drop summer electric usage measurably. We document pre- and post-work conditions so you can verify the change.

Radiant Barrier Installation in Kyle

Kyle’s attic temperatures routinely hit 150°F in summer, and in production-built homes with dark shingles and minimal ventilation, radiant heat gain through the roof deck is the single largest source of cooling load after air leakage. Radiant barrier installation reflects that infrared energy back toward the roof deck rather than letting it radiate into the attic space and down through the insulation. In subdivisions off Kyle Parkway and Yarrington Road where builders spec’d minimum R-value and no radiant barrier, this upgrade often delivers the fastest payback of any attic improvement. Radiant Barrier Installation covers material specifications and how we integrate it with air sealing.

Attic Radiant Barrier

Signs you need it

Your attic feels like a furnace by 10 a.m., your AC runs continuously on sunny afternoons, or rooms with cathedral ceilings stay hotter than the rest of the house.

What it costs in Kyle

Attic radiant barrier installation in Kyle typically runs $1,500-$3,500 for standard gable-roof homes under 2,500 square feet, with complex rooflines or steep pitches at the higher end.

How we do it

We staple perforated radiant barrier foil across the bottom of rafters or lay it over existing attic insulation, maintaining ventilation paths and ensuring it doesn’t trap moisture, then verify with thermal imaging.

Radiant Barrier Roof Deck

Signs you need it

You’re re-roofing or building an addition and want the barrier integrated at the roof deck rather than retrofitting into an existing attic.

What it costs in Kyle

Radiant barrier roof deck application in Kyle typically runs $2,000-$4,500 when done during re-roofing, or $3,000-$6,000 as a standalone retrofit with decking access.

How we do it

We apply radiant barrier sheathing or spray-applied low-emissivity coating directly to the roof deck underside, sealing all edges to create a continuous reflective surface that works with - not against - attic ventilation.

What Radiant Barrier Installation Costs in Kyle

Does radiant barrier work with spray foam in Kyle?

Radiant barrier and spray foam serve different functions - barrier reflects radiant heat, foam stops air leakage and provides R-value - so in Kyle’s climate they complement each other in vented attics but are redundant in fully conditioned, unvented spray foam attics. We specify based on your attic configuration, not by selling both.

How much can radiant barrier lower my attic temperature?

A properly installed radiant barrier typically reduces attic surface temperatures by 20-35°F in Kyle’s summer conditions, which translates to less heat radiating into living spaces and shorter AC run times. We measure with thermal imaging before and after so you see the difference.

Insulation Removal & Replacement in Kyle

Insulation removal and replacement in Kyle is most common in two situations: post-2015 production homes where compressed, gapped batts never performed to spec, and older homes near the historic district or Kyle Parkway where decades of rodent activity, water damage, or vermiculite contamination have made the existing material a liability rather than an asset. In either case, we don’t add new insulation over damaged old material - we remove it, inspect and seal the cavity, then install new product to a documented R-value. Insulation Removal & Replacement details our containment and disposal process.

Contaminated Insulation Removal

Signs you need it

You’ve found rodent droppings in the attic, smelled urine near ceiling vents, or seen insulation stained with water marks or mold.

What it costs in Kyle

Contaminated insulation removal in Kyle typically runs $2,000-$4,500 for attics under 1,500 square feet, with HEPA containment, sanitizing, and disposal included in the written scope.

How we do it

We set up negative-air containment, remove contaminated material with sealed bags, HEPA-vacuum all surfaces, apply enzymatic sanitizer, and provide photo documentation before any new insulation is specified.

Insulation Replacement

Signs you need it

Your attic insulation is compressed below the joist tops, has settled unevenly leaving bare spots, or was installed at R-30 when R-38 or R-49 was specified.

What it costs in Kyle

Insulation replacement in Kyle typically runs $2,500-$5,500 for full attic removal and reinstall to R-38 or R-49, with air sealing included before the new material goes in.

How we do it

We remove old material, blower-door test and seal all leaks, install baffles at eaves for ventilation, then blow in new fiberglass or cellulose to a uniform depth with depth markers for verification.

What Insulation Removal & Replacement Costs in Kyle

Is it cheaper to remove and replace or just add more insulation?

Adding over damaged, compressed, or contaminated insulation traps the problem and often violates manufacturer warranty - removal and replacement costs more upfront but is the only approach that delivers the performance you’re paying for. We price both ways so you can see the difference.

Do you test for asbestos before removing old insulation?

We visually inspect for vermiculite and suspect materials, and if we find anything that tests positive for asbestos, we stop work and refer you to a licensed abatement contractor - we do not handle asbestos removal. This is noted in every written scope before we start.

Attic Air Sealing in Kyle

Attic air sealing is the single highest-leverage upgrade for Kyle’s production-built homes, and it’s the step most builders skipped to hit price points in the 2015-2023 boom. In subdivisions off Yarrington Road and throughout the 78640 ZIP code, we regularly find top plates unsealed, can lights venting directly into attics, and HVAC boots pulling 150°F air into ductwork every summer. A blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - typically reveals 3,500-5,500 CFM50 in these homes, when 2,000 or below is achievable. Attic Air Sealing explains how we hit those numbers.

Top Plate & Penetration Sealing

Signs you need it

Your attic has visible gaps where interior walls meet the ceiling, you feel drafts at outlets on exterior walls, or your blower-door test came back above 3,000 CFM50.

What it costs in Kyle

Top plate and penetration sealing in Kyle typically runs $1,200-$2,800 for standard production homes, with larger or more complex framing at the higher end.

How we do it

We access top plates from the attic, remove existing insulation as needed, seal all gaps with fire-rated caulk and foam, seal wire and pipe penetrations, then replace insulation and verify with a post-sealing blower-door test.

Can Light & Duct Boot Sealing

Signs you need it

You have recessed can lights in rooms below the attic, your HVAC ducts show dust streaks at connections, or rooms farthest from the air handler never reach set temperature.

What it costs in Kyle

Can light and duct boot sealing in Kyle typically runs $800-$2,000 depending on fixture count and whether we need to install fire-rated covers or replace non-IC-rated housings.

How we do it

We install fire-rated airtight covers over each can light, seal all duct boots and connections with mastic, seal the platform around each boot to the drywall, and pressure-test the duct system where accessible.

What Attic Air Sealing Costs in Kyle

Can attic air sealing be done without removing all the insulation?

We remove insulation only where we need access to top plates, can lights, and penetrations, then replace it when sealing is complete - most Kyle attics need partial removal, not full strip-down, which keeps cost and disruption down. The written scope specifies exactly what comes out and what goes back.

How much does air sealing lower my blower-door number?

In Kyle’s production-built homes, comprehensive attic air sealing typically reduces CFM50 by 25-40%, with the biggest drops coming from sealing can lights and top plates that were left completely open. We give you before-and-after numbers in writing, with the photos to match.

Wall Insulation in Kyle

Wall insulation in Kyle addresses the homes that were built with empty stud cavities or with fiberglass batts that settled, compressed, or were never fully installed behind electrical boxes and windows. In the post-2010 production subdivisions that dominate Kyle’s housing stock, exterior walls often have R-13 batts with gaps at every penetration, while pre-boom homes near the historic district may have no wall insulation at all. Because Kyle’s cooling season runs April through October, uninsulated or poorly insulated walls create the hot-spot effect - rooms with western exposure that never cool down despite the AC running. Wall Insulation covers our methods for finished and unfinished walls.

Injection Foam Wall Insulation

Signs you need it

Your exterior walls feel hot to the touch in summer, you have rooms with western exposure that stay 5-10°F warmer, or your home was built before 2010 with empty or settled wall cavities.

What it costs in Kyle

Injection foam wall insulation in Kyle typically runs $3,500-$7,500 for a 2,000-square-foot home, with two-story construction or dense-pack cellulose at the lower end and closed-cell foam at the higher end.

How we do it

We drill 2-inch holes through exterior siding or interior drywall at stud-bay spacing, inject foam or dense-pack cellulose to fill the cavity completely, seal the holes with matching plugs, and verify fill with thermal imaging from inside.

Drill & Fill Wall Insulation

Signs you need it

You’ve confirmed empty stud cavities with an infrared camera or by removing a switch plate, or you’re remodeling and have wall access before drywall goes up.

What it costs in Kyle

Drill and fill wall insulation in Kyle typically runs $2,500-$5,500 for standard single-story homes, with open interior access during renovation reducing cost toward the lower end.

How we do it

We drill access holes at the top and bottom of each stud bay, blow in cellulose or fiberglass to verified density, seal all holes, and provide depth and density documentation for each cavity filled.

What Wall Insulation Costs in Kyle

Will injection foam damage my drywall?

Injection foam expands slowly and is formulated for retrofit applications - in hundreds of Kyle-area jobs, we’ve had zero drywall blowouts when cavities are properly assessed first. We check for obstructions, electrical boxes, and existing conditions before injecting, and this is in the written scope.

Can you insulate walls without tearing out drywall?

Yes - drill-and-fill and injection foam methods work through small exterior or interior holes that we patch and paint to match, making wall insulation viable for finished homes without major disruption. We specify the access method in your written price before work starts.

Attic Cleaning & Rodent Proofing in Kyle

Attic cleaning and rodent proofing in Kyle is a direct consequence of the area’s rapid development: new subdivisions pushed into former habitat, and roof rats, squirrels, and mice found easy access through construction gaps in homes built quickly for volume. In attics across the 78610 and 78640 ZIP codes, we find contaminated insulation, chewed wires, and entry points at roof vents, soffit intersections, and pipe penetrations that were never sealed. The February 2021 freeze drove even more rodents into attics for warmth, and many Kyle homeowners are still discovering the damage. Attic Cleaning & Rodent Proofing details our exclusion protocol.

Attic Sanitizing & Decontamination

Signs you need it

You’ve found rodent droppings, nesting material, or urine stains in your attic, or you smell mustiness that gets worse when the HVAC runs.

What it costs in Kyle

Attic sanitizing and decontamination in Kyle typically runs $1,500-$3,500 for attics under 1,500 square feet, with heavy contamination or large attic footprints at the higher end.

How we do it

We remove contaminated insulation and debris, HEPA-vacuum all surfaces, apply enzymatic sanitizer to break down organic material and odor, and provide photo documentation of the cleaned space before any new work is specified.

Rodent Proofing & Exclusion

Signs you need it

You hear scratching in the attic at night, you’ve found droppings near the water heater or in the garage, or you’ve had recurring rodent issues despite trapping.

What it costs in Kyle

Rodent proofing and exclusion in Kyle typically runs $1,200-$2,800 for standard single-family homes, with steep roofs, multiple stories, or extensive construction-gap sealing at the higher end.

How we do it

We inspect the roofline, soffits, vents, and foundation for all entry points, seal gaps with rodent-proof materials, install hardware cloth over vents, and provide a written map of every entry point found and sealed.

What Attic Cleaning & Rodent Proofing Costs in Kyle

How do I know if rodents are in my attic or walls?

Scratching at dusk or dawn, droppings near attic access or in the garage, and chewed wires or insulation are the most reliable indicators - we confirm with inspection cameras and provide photos of what we find. Call (737) 337-8049 and we’ll schedule a documented inspection.

Will rodent proofing keep all pests out permanently?

Our exclusion work seals every entry point we can access, but rodents can create new openings if motivated - we warranty our sealing for one year and recommend annual roofline inspection, which we document with photos. The written scope specifies what’s covered.

Home Energy Audit in Kyle

A home energy audit in Kyle is the starting point for homeowners who want to stop guessing and start measuring - especially in production-built homes where the builder’s insulation certificate rarely matches what we find in the attic. Our audit combines blower-door testing, thermal imaging, and combustion safety checks to produce a prioritized list of envelope improvements with estimated savings, so you can decide what to do and in what order. In Kyle’s Climate Zone 2, where cooling dominates and the February 2021 freeze proved how fragile minimum-code construction can be, an audit turns “my house is uncomfortable” into “here’s exactly where the air and heat are moving, and what it costs to fix it.” Home Energy Audit explains what’s included and how we deliver results.

Blower Door Test

Signs you need it

Your home feels drafty, rooms have uneven temperatures, or you’re considering any insulation or air-sealing work and want a baseline before spending money.

What it costs in Kyle

A standalone blower-door test in Kyle typically runs $300-$500, or it’s included at no additional charge when bundled with a full home energy audit.

How we do it

We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, measure CFM50 - the cubic feet per minute of air leakage at standard pressure - then walk the house with a smoke pencil to locate the biggest leaks.

Thermal Imaging Inspection

Signs you need it

You have rooms that never reach temperature, suspect missing insulation in walls or ceilings, or want visual proof of where heat is entering or escaping before authorizing work.

What it costs in Kyle

Thermal imaging inspection in Kyle typically runs $250-$450 as a standalone service, or included within a full energy audit; we provide digital images with temperature readings for every anomaly found.

How we do it

We scan all exterior walls, ceilings, windows, and doors with a FLIR camera during blower-door depressurization to make air leaks visible, then annotate each image with the probable cause and recommended fix.

What Home Energy Audit Costs in Kyle

How long does a home energy audit take in Kyle?

Most Kyle audits take 2.5 to 4 hours depending on house size, with the blower-door test and thermal imaging done on-site and the written report with prioritized recommendations delivered within 48 hours. We schedule audits with a live person, not a callback queue.

Will an audit tell me if I need new insulation or just air sealing?

Yes - the audit distinguishes between air leakage (which blower-door testing quantifies) and missing or degraded insulation (which thermal imaging and visual inspection reveal), so you know whether to budget for sealing, insulation, or both. We never recommend insulation over an unsealed attic.

Brands We Service in Kyle

We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary product lock-in means we specify what’s right for your home, not what a manufacturer requires us to sell. Most Kyle jobs draw from locally stocked Rockwool and CertainTeed inventory with next-day availability. our brands
