Insulation in Selma, TX
Crawl space encapsulation and vapor barrier work in Selma typically runs $3,200-$6,800 for a full encapsulation, with most jobs completed in one to two days. The 1990s-2010s tract homes that dominate Selma were built with vented crawl spaces and minimal ground sealing, leaving floor joists exposed to the humid Gulf air that rolls up the I-35 corridor. We seal first, then insulate - in that order - and every crawl space job starts with a written price before any work begins. Call (830) 402-5240 for a free estimate.
Why Selma Homes Are Different
Selma developed almost entirely during the suburban boom of the 1990s through 2010s along the Loop 1604/I-35 corridor. The vast majority of its housing stock is now 15-30 years old and was built to pre-IECC 2009 minimum insulation standards. Blown-in attic insulation in these tract homes has settled and compressed after decades of San Antonio’s extreme heat cycling - attic cavities routinely hit 140°F-plus in summer - making attic top-offs and air-sealing upgrades the defining insulation job in this specific market cohort.
The February 2021 Winter Storm Uri exposed how inadequate many of these tract homes’ thermal envelopes are against cold snaps, spurring renewed demand for comprehensive insulation assessments. Selma’s brick-veneer construction with vented attics and standard 2×4 framed walls means we see the same pattern repeatedly: original fiberglass batts in walls performing below their labeled R-value, and attic insulation settled well below its installed depth. Homes from the first development wave, mid-1990s to early 2000s, are now at the age where full removal and replacement is often more cost-effective than topping off degraded material.
Our Main Selma Services
Most Selma homeowners who call us start with one of these three services, each with its own dedicated page.
Attic Insulation in Selma
Attic insulation in Selma means addressing settled blown-in fiberglass or cellulose in 15-30 year old vented attics that have baked through thousands of 140°F summer days. We assess what’s there, measure current R-value against the original design, and recommend either a top-off with Owens Corning loose-fill or full removal and replacement when the existing material has degraded. Every attic job includes air sealing of top plates and penetrations before any new insulation goes in - we won’t blow insulation over an unsealed attic floor. Attic Insulation in Selma covers our full process and pricing.
Spray Foam Insulation in Selma
Spray foam insulation in Selma works best for roofline encapsulation, bonus rooms over garages, and the commercial warehouse strip at the Loop 1604/I-35 interchange where aging early-2000s roofline foam needs replacement. We use open-cell and closed-cell products from Demilec and Icynene, selected by application rather than brand loyalty. For residential work, roofline foam converts vented attics to conditioned space, eliminating the 140°F attic problem entirely. Spray Foam Insulation in Selma details open-cell versus closed-cell and where each fits.
Blown-In Insulation in Selma
Blown-in insulation in Selma is the most common attic upgrade for the city’s 1990s-2010s housing stock, whether adding fiberglass or cellulose over settled existing material or starting fresh after removal. We use GreenFiber cellulose and Owens Corning fiberglass loose-fill, blown to specified depth with depth markers visible across the attic floor. Every blown-in job follows air sealing - top plates, can lights, duct boots, and penetrations sealed with foam and caulk before the blower truck arrives. Blown-In Insulation in Selma has full pricing and application details.

Crawl Space Encapsulation & Vapor Barrier in Selma
Crawl space encapsulation and vapor barrier work in Selma addresses a specific problem: the 1990s-2010s tract homes built along the Loop 1604/I-35 corridor were constructed with vented crawl spaces and thin 6-mil poly sheeting, if any ground cover was installed at all. The humid subtropical climate means crawl spaces here stay damp year-round, with summer dew points regularly pushing wood moisture content above the 20% threshold where mold colonizes and structural decay accelerates. Crawl Space Encapsulation & Vapor Barrier is our primary service for these conditions.
Crawl Space Encapsulation
Signs you need it
Your crawl space needs encapsulation if you notice musty odors rising through floor registers, sagging fiberglass batts hanging between joists, or visible mold on wood surfaces.
What it costs in Selma
Full crawl space encapsulation in Selma typically ranges from $3,200 to $6,800 depending on square footage, foundation wall height, and whether a dehumidifier is required.
How we do it
We install a reinforced 12-20 mil vapor barrier across the entire ground surface, sealed at seams and extended up foundation walls, then close vents and condition the space with a dedicated dehumidifier or supply-air connection.
Crawl Space Moisture Control
Signs you need it
Moisture control becomes necessary when relative humidity in the crawl space consistently exceeds 70%, condensate forms on ductwork and pipes, or pest activity increases due to damp conditions.
What it costs in Selma
Crawl space moisture control systems in Selma, including sump pumps and perimeter drainage, typically run $1,800 to $4,500 depending on groundwater conditions and drainage complexity.
How we do it
We grade the ground surface to a central sump pit, install perimeter drainage where needed, seal the vapor barrier to a sump lid, and add a commercial-grade dehumidifier with condensate pump discharge.
What Crawl Space Encapsulation & Vapor Barrier Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Full encapsulation (vapor barrier, sealed vents, dehumidifier) | $3,200 - $6,800 |
| Vapor barrier only (ground and wall sealing, no conditioning) | $1,500 - $3,200 |
| Moisture control with sump pump and drainage | $1,800 - $4,500 |
How long does crawl space encapsulation take in Selma?
Most Selma crawl space encapsulations are completed in one to two days, with larger or more complex jobs requiring up to three days. We provide a written timeline with the written price before any work starts.
Will encapsulation affect my HVAC efficiency?
Yes - encapsulating a vented crawl space typically reduces heating and cooling loads by 15-25% by eliminating the thermal bridge to damp, unconditioned air below the floor. We document pre- and post-conditions with photos and, where applicable, blower-door readings.
Radiant Barrier Installation in Selma
Radiant barrier installation in Selma targets the specific thermal load that dominates this market: five-plus months of 90°F-plus temperatures that drive attic temperatures far above 140°F, radiating heat downward through ductwork and ceiling drywall. The 1990s-2010s tract homes here were built with vented attics and no radiant barrier, meaning the roof deck acts as a solar collector all summer long. Radiant Barrier Installation is our most cost-effective retrofit for cooling-dominated energy bills.
Attic Radiant Barrier
Signs you need it
Your attic needs a radiant barrier if second-floor rooms stay hot past 10 PM, your AC runs continuously on summer afternoons, or ceiling surfaces feel warm to the touch.
What it costs in Selma
Attic radiant barrier installation in Selma typically ranges from $1,200 to $2,800 for a standard 2,000-2,500 square foot home, depending on attic configuration and access.
How we do it
We staple perforated radiant barrier foil across the bottom of rafters or lay it over existing attic insulation, ensuring proper ventilation paths are maintained and electrical clearances are observed.
Radiant Barrier Roof Deck
Signs you need it
Roof deck radiant barrier makes sense during re-roofing or when the existing roof deck is accessible, particularly if you’re already replacing shingles or addressing hail damage.
What it costs in Selma
Radiant barrier roof deck application in Selma, typically done during re-roofing, adds $800 to $1,800 to the roofing project depending on roof pitch and square footage.
How we do it
We apply radiant barrier sheathing or foil-faced decking directly to the roof structure during tear-off, creating a continuous reflective surface that blocks radiant heat before it enters the attic space.
What Radiant Barrier Installation Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Attic radiant barrier (foil stapled to rafters or laid over insulation) | $1,200 - $2,800 |
| Radiant barrier roof deck (during re-roofing) | $800 - $1,800 |
| Radiant barrier with attic air sealing package | $2,000 - $4,200 |
Does radiant barrier work with existing insulation?
Yes - radiant barrier complements existing insulation by addressing the radiant heat transfer that fiberglass and cellulose cannot block, and we install it without disturbing settled material unless removal is already indicated.
How much can radiant barrier lower my cooling bill?
Selma homeowners typically see 5-15% cooling cost reduction after radiant barrier installation, with the greatest savings in homes with dark shingle roofs and minimal existing shade coverage.
Insulation Removal & Replacement in Selma
The 140°F attic temperatures here accelerate binder breakdown and settling, and many of these homes also have rodent activity, water damage, or remodeling debris mixed into the insulation layer. Insulation Removal & Replacement lets us start with a clean, sealed envelope before installing new material.
Attic Insulation Removal
Signs you need it
Attic insulation needs removal when you can see the ceiling drywall between joists, smell urine or mold when the HVAC runs, or find multiple pest entry points with nesting material.
What it costs in Selma
Attic insulation removal in Selma typically runs $1.50 to $3.50 per square foot, or $1,800 to $4,500 for a standard 2,000 square foot home depending on contamination level and access difficulty.
How we do it
We use commercial vacuums with HEPA filtration to remove all loose material, bag it for proper disposal, then inspect and document the deck condition before any air sealing or new insulation begins.
Contaminated Insulation Removal
Signs you need it
Contaminated insulation removal is necessary after roof leaks, plumbing failures, or rodent infestations where biological contamination makes the material a health hazard rather than just ineffective.
What it costs in Selma
Contaminated insulation removal in Selma, including sanitizing and deodorizing, typically ranges from $2.50 to $5.00 per square foot depending on contamination type and required PPE protocols.
How we do it
Our crew wears appropriate respiratory protection, removes contaminated material in sealed bags, applies enzymatic cleaners and antimicrobial treatments to affected surfaces, and verifies safe conditions before new insulation installation.
What Insulation Removal & Replacement Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Standard attic insulation removal | $1,800 - $4,500 |
| Contaminated insulation removal with sanitizing | $3,000 - $7,500 |
| Removal plus replacement with new blown-in insulation | $3,500 - $8,500 |
Can you remove insulation without tearing out my ceiling?
Yes - all our attic insulation removal is done through the attic access or roof vents with vacuum equipment; we do not cut into finished ceilings unless there’s a separate structural or plumbing repair needed.
How do I know if removal or a top-off is the better choice?
We recommend removal when the existing material is below 50% of its original depth, shows signs of moisture damage or pest activity, or contains vermiculite or other hazardous materials - otherwise, air sealing plus a top-off is usually more cost-effective.
Attic Air Sealing in Selma
Attic air sealing in Selma is the foundational step we never skip - the Haven Standard requires sealing before insulating, and Selma’s 1990s-2010s tract homes are particularly leaky at top plates, can light penetrations, and duct boots. The extreme attic temperatures here mean every cubic foot of conditioned air that escapes into the attic costs more to replace than in milder climates, and the pressure differential between a hot attic and cooled living space drives significant exfiltration through these gaps. Attic Air Sealing is documented with before-and-after blower-door numbers on every applicable job.
Top Plate & Penetration Sealing
Signs you need it
Top plate sealing is needed when you feel drafts at ceiling corners, see dusty streaks around ceiling fixtures, or notice your attic insulation is darkened by filtered air near wall plates.
What it costs in Selma
Top plate and penetration sealing in Selma typically ranges from $800 to $2,200 for a standard home, depending on the number of interior walls and complexity of wiring and plumbing penetrations.
How we do it
We access the attic floor, remove insulation from plate lines, seal all gaps between top plates and drywall with expanding foam and caulk, then replace insulation and verify with blower-door testing.
Can Light & Duct Boot Sealing
Signs you need it
Can light and duct boot sealing is indicated when you feel conditioned air entering the attic around recessed fixtures, see condensation on duct boots, or find disconnected flex duct lying on insulation.
What it costs in Selma
Can light and duct boot sealing in Selma typically runs $400 to $1,200 depending on the number of fixtures and whether boots require reconnection or replacement.
How we do it
We install fire-rated covers over non-IC can lights, seal with high-temperature caulk, mastic-seal all duct connections, and support flex duct properly to prevent future disconnection.
What Attic Air Sealing Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Top plate and penetration sealing | $800 - $2,200 |
| Can light and duct boot sealing | $400 - $1,200 |
| Full attic air sealing (comprehensive package) | $1,500 - $3,500 |
Will air sealing make my attic hotter?
No - air sealing stops conditioned air from escaping into the attic, but proper ventilation through soffit and ridge vents remains intact; in fact, by reducing moisture load, sealed attics often perform better thermally.
How do you prove air sealing worked?
We provide before-and-after blower-door test results - a pressurization reading that shows, in one number, how much air your building envelope was losing before and after our work - typically seeing 20-40% reduction in CFM50.
Wall Insulation in Selma
Wall insulation in Selma addresses the original code-minimum fiberglass batts installed in 2×4 framed walls during the 1990s-2010s construction boom, which perform at roughly R-11 to R-13 - well below current IECC standards and inadequate for the temperature extremes this climate produces. The February 2021 Winter Storm Uri demonstrated how quickly these thin walls lose heat when outdoor temperatures drop below 20°F, and summer heat gain through west-facing walls creates persistent hot spots that HVAC systems struggle to balance. Wall Insulation offers retrofit solutions without full gut renovation.
Injection Foam Wall Insulation
Signs you need it
Injection foam makes sense when exterior walls feel hot or cold to the touch, rooms on the home’s west side stay uncomfortably warm, or you’re undertaking exterior siding replacement that provides access.
What it costs in Selma
Injection foam wall insulation in Selma typically ranges from $3.50 to $6.50 per square foot of wall area, or $4,500 to $9,000 for a full home depending on wall height and access.
How we do it
We drill 2-inch holes through exterior siding or interior drywall at stud cavity intervals, inject slow-rise foam that fills around existing wiring and plumbing, then patch and match finishes.
Drill & Fill Wall Insulation
Signs you need it
Drill and fill with cellulose or fiberglass is appropriate when walls are empty or contain degraded batts, particularly in homes with aluminum siding or other cladding that’s easy to remove and replace.
What it costs in Selma
Drill and fill wall insulation in Selma typically runs $2.50 to $4.50 per square foot, or $3,200 to $6,500 for a full home using GreenFiber cellulose or Johns Manville fiberglass.
How we do it
We remove cladding or drill through exterior sheathing, blow cellulose or fiberglass to specified density using fill tubes that reach cavity bottoms, verify with thermal imaging, then restore finishes.
What Wall Insulation Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Injection foam (full home) | $4,500 - $9,000 |
| Drill and fill cellulose or fiberglass (full home) | $3,200 - $6,500 |
| Exterior wall insulation during siding replacement | $2,800 - $5,500 |
Can you insulate walls without removing drywall?
Yes - both injection foam and drill-and-fill methods access wall cavities from the exterior or through small interior holes, with patching that matches existing texture and paint.
Will wall insulation help with sound as well as temperature?
Dense-packed cellulose and injection foam both provide significant sound dampening between rooms and from exterior noise, particularly traffic on I-35 and Loop 1604 - though we do not promise specific STC ratings.
Attic Cleaning & Rodent Proofing in Selma
Attic cleaning and rodent proofing in Selma is frequently the first step before insulation work can begin, as the settled blown-in fiberglass in 1990s-2010s homes provides ideal nesting material for roof rats and squirrels common to the San Antonio metro’s oak-dominated neighborhoods. The warm attic temperatures and proximity to greenbelts along Salado Creek and other drainage corridors mean Selma homes see consistent rodent pressure, with entry points often at construction gaps in eaves, unsealed roof vents, and plumbing penetrations. Attic Cleaning & Rodent Proofing restores safe, usable attic space.
Attic Sanitizing & Decontamination
Signs you need it
Attic sanitizing is needed when you smell ammonia or musk through ceiling fixtures, find droppings or urine stains on insulation, or have had confirmed rodent activity within the past year.
What it costs in Selma
Attic sanitizing and decontamination in Selma typically ranges from $1,200 to $3,200 depending on contamination extent, attic square footage, and whether insulation removal is required first.
How we do it
We remove contaminated material, HEPA-vacuum all surfaces, apply enzymatic cleaners and botanical disinfectants, and run air scrubbers until particulate counts drop to safe levels before any new work begins.
Rodent Proofing & Exclusion
Signs you need it
Rodent proofing is necessary when you hear scratching at night, find chewed wires or ductwork, or see entry gaps larger than 1/4 inch at eaves, vents, or roof junctions.
What it costs in Selma
Rodent proofing and exclusion in Selma typically runs $800 to $2,500 depending on home size, number of entry points, and whether one-way doors or trapping is needed for existing animals.
How we do it
We inspect the roofline and foundation with photo documentation, seal all entry points with rodent-resistant materials - steel mesh, concrete, or metal flashing - and provide a written warranty on our exclusion work.
What Attic Cleaning & Rodent Proofing Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Attic sanitizing and decontamination | $1,200 - $3,200 |
| Rodent proofing and exclusion | $800 - $2,500 |
| Full attic restoration (cleaning, proofing, re-insulation) | $3,500 - $8,000 |
Do you trap and remove live rodents?
We coordinate with licensed wildlife operators for live animal removal when needed, then perform the structural exclusion to prevent re-entry - our warranty covers the proofing, not the trapping.
How do I know if rodents have damaged my insulation?
We document insulation condition with photos during our initial inspection - look for tunneling patterns, compressed trails, scattered droppings, or urine staining that indicates the material needs removal before new insulation is installed.
Home Energy Audit in Selma
A home energy audit in Selma provides the documented baseline that every other insulation decision should build from, particularly for the 1990s-2010s tract homes where multiple systems - HVAC, ductwork, insulation, air sealing - interact in ways that single-fix approaches miss. The extreme summer attic temperatures and the thermal envelope failures exposed by Winter Storm Uri mean Selma homeowners need whole-system analysis rather than guesswork about which upgrade delivers the best return. Home Energy Audit is where we start every comprehensive project.
Blower Door Test
Signs you need it
A blower door test is indicated when rooms are unevenly heated or cooled, energy bills seem high for your home size, or you’re planning insulation upgrades and want to prioritize air sealing against insulation.
What it costs in Selma
A standalone blower door test in Selma typically ranges from $300 to $600, or is included as part of a comprehensive home energy audit package.
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 air leakage at standard pressure - to quantify total envelope leakage and identify major leak locations.
Thermal Imaging Inspection
Signs you need it
Thermal imaging reveals insulation gaps, air leaks, and moisture issues that visual inspection cannot detect, particularly valuable in Selma’s homes where settled attic insulation creates invisible thermal bypasses.
What it costs in Selma
Thermal imaging inspection in Selma typically runs $250 to $500 as a standalone service, or is bundled with a full energy audit for $400 to $800 total.
How we do it
We scan the building envelope with a FLIR infrared camera during blower-door-induced pressure difference, documenting temperature variations that indicate missing insulation, thermal bridging, or active air leakage paths.
What Home Energy Audit Costs in Selma
| Item | Typical range in Selma |
|---|---|
| Standalone blower door test | $300 - $600 |
| Thermal imaging inspection | $250 - $500 |
| Comprehensive home energy audit (blower door, thermal imaging, insulation inspection, duct leakage test) | $400 - $800 |
What does a home energy audit include in Selma?
Our comprehensive audit includes blower-door testing, thermal imaging, insulation R-value measurement, duct leakage testing, and a written report with prioritized recommendations and estimated costs for each improvement.
Can I use audit results for utility rebates?
Yes - our audit documentation meets CPS Energy and Texas gas utility rebate program requirements; we provide the specific forms and test results needed for submission with your application.
