Trusted Attic Insulation for Converse Homeowners
Most attic insulation jobs in Converse run between $1,800 and $4,200 depending on attic size, existing material condition, and whether air sealing is needed first. We complete most installations in a single day, and we won’t start until you have a written price in hand. Call (830) 420-0953 to schedule a free estimate with documented photo record included.
We’ve sealed and insulated more than 9,000 homes since 2016, and we’ve learned that blowing new insulation over a leaky attic floor is throwing money into the wind. In Converse, where summer attic temperatures regularly hit 140°F and winter cold snaps dip below freezing, your attic is the single largest thermal weak point in your home. Homes near Randolph Air Force Base, in the older neighborhoods off FM 78, and in the newer builds around Converse North Park all share the same problem: conditioned air escaping through gaps in the top plates, can light housings, and plumbing chases. We treat air sealing as a hard prerequisite, not an upsell. Every job that qualifies gets before-and-after blower-door numbers so you can see the actual performance change, not just take our word for it.
Our crews are background-checked, uniformed, and arrive with a written scope, written warranty, and flat price already agreed to. Under Haven Standard Clause 1, no work starts without it. Calls are answered by a live person 24/7, and you’ll get a text when your technician is on the way with a named arrival window.
What Our Attic Insulation Service Includes
Blown-In Attic Insulation
Blown-in insulation, also called loose-fill, is cellulose or fiberglass material blown through a hose to create a continuous thermal blanket across your attic floor. In Converse, we typically install this in homes built between 1970 and 2010 where the original Attic Batt Insulation has settled below the ceiling joists, leaving thermal bridges every 16 inches. We use Owens Corning AttiCat and GreenFiber cellulose systems, and we never blow over an unsealed attic. Our crew seals all top plates, electrical penetrations, and duct boots first, then blows to the depth specified in your written scope, usually R-38 to R-60 for this climate zone.
Attic Batt Insulation
Batt insulation comes in pre-cut fiberglass or mineral wool panels sized to fit between standard joist spacing. We install batts in Converse homes with limited attic access where a blower hose won’t reach, or where the homeowner needs targeted spot repairs after partial removal. Johns Manville batts are our standard for mineral wool jobs in this market because of their fire resistance rating and dimensional stability in high-humidity attics. Every batt installation includes compression-free placement and proper vapor barrier orientation, documented in your photo record.
Attic Insulation Top-Up
An Attic Insulation Top-Up adds material over existing insulation that is in good condition but has settled below current energy code levels. This is common in Converse’s 1990s and 2000s subdivisions where builders installed R-30 or less to meet minimum code at the time. We test existing material for moisture damage, rodent contamination, and proper depth before recommending a top-up. If the existing layer is clean, we air seal and blow new material to achieve your target R-value, typically at 40% lower cost than full replacement. Your written price will show the exact depth and R-value you’re paying for.
Attic Insulation Replacement
Attic Insulation Replacement removes existing material down to the ceiling drywall, then installs new insulation with complete air sealing. We recommend this for Converse homes with water-damaged insulation from roof leaks, rodent-affected attics in the older neighborhoods near Converse City Park, or any home where the existing material contains vermiculite or other hazardous products. Removal is performed with HEPA-contained vacuums, and we provide photo documentation of the clean deck before any new material goes in. Replacement jobs always include our full air-sealing protocol and blower-door verification.
Attic Baffles & Ventilation Prep
Baffles, also called rafter vents or vent chutes, maintain the air channel from soffit vents up to ridge vents in vented attic assemblies. Without them, blown insulation blocks soffit intake and creates moisture traps. In Converse’s humid subtropical climate, this means mold, deck rot, and ice damming in winter. We install Knauf Attic Baffles & Ventilation Prep or site-built foam board chutes on every job where soffit ventilation exists, ensuring the ventilation path stays open for the life of the insulation. This step is included in your written scope, not treated as an add-on.

Brands We Service for Attic Insulation
We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, among others. With Owens Corning, we’ve installed thousands of bags of their AttiCat expanding fiberglass system in Bexar County attics. The AttiCat machine conditions the material as it blows, reducing settling and achieving labeled R-value at lower installed weight. We don’t push proprietary products or lock you into a single manufacturer. Your written scope specifies the exact material, brand, and R-value you’re receiving.
GreenFiber cellulose is our go-to for homeowners prioritizing recycled content and sound attenuation. We’ve found it performs particularly well in Converse’s older homes with irregular joist spacing, where cellulose’s ability to fill voids outperforms batt products. Whether you have a preference for fiberglass, mineral wool, or cellulose, or you’re bringing us a competing quote to review under our Free Second Opinion policy, we’ll specify the right product for your attic’s condition and your budget. We have no exclusive arrangements with any manufacturer.
Before
AfterSigns You Need Attic Insulation Right Now
- Your second floor is 8-12°F hotter than your first floor in summer. This temperature split is the classic signature of an under-insulated or unsealed attic in Converse’s climate. Hot attic air radiates through the ceiling plane, overwhelming your HVAC system’s capacity to maintain setpoint upstairs. We measure this split during our assessment and target it with proper R-value and air sealing.
- Your energy bills spike every July and August despite normal thermostat settings. When attic temperatures exceed 130°F, your ductwork in the attic gains 15-25°F before air ever reaches your vents. If your summer electric bills are running $300+ for a 2,000 square foot home, the attic is the first place to look. Our blower-door test will show you exactly how much conditioned air you’re losing to the attic.
- You can see ceiling joists through your existing insulation. Insulation settles over time. Fiberglass batts lose 10-20% of their thickness in the first five years. If the pink or yellow material sits below the top of the joists, you’re well below the R-38 minimum recommended for Converse’s climate zone. We measure actual depth, not labeled thickness, and calculate your real R-value.
- Ice dams formed on your roof edges last winter. Ice dams occur when warm attic air melts snow at the roof peak, which refreezes at the cold eave. They’re common in Converse during our occasional hard freezes, and they indicate both insufficient insulation and air leaks at the ceiling plane. Left unaddressed, they destroy shingles, gutters, and drywall.
- Your attic has visible mold, water staining, or rodent droppings. These are not just insulation problems. They’re symptoms of ventilation failure, air leakage, or pest entry that must be corrected before new insulation goes in. We document these conditions in your photo record, quote remediation separately if needed, and never bury a problem under new material.
Our Attic Insulation Process - Step by Step
- 1
Schedule your free estimate. Call (830) 420-0953 and a live person will answer, 24/7. We’ll confirm your address in Converse, ask about your home’s age, square footage, and any specific problems you’ve noticed. You’ll receive a text confirmation with your technician’s name and arrival window. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
On-site assessment with blower-door test. Your technician performs a visual inspection of the attic access, existing insulation depth and condition, and ventilation configuration. On applicable jobs, we run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. Typical pre-work readings in Converse homes range from 3,500 to 6,000 CFM50 depending on age and construction quality.
- 3
Written scope, written price, written warranty. Before any work starts, you receive a flat price with no hidden charges, a detailed scope specifying materials, depths, and R-values, and our 365-Day Done Right Promise in writing. This is Haven Standard Clause 1, and it’s non-negotiable. We also offer a Free Second Opinion on any competing written estimate.
- 4
Air sealing first, then insulation. Our crew seals all top plates, electrical and plumbing penetrations, can light housings, duct boots, and chimney chases with fire-rated foam, caulk, and rigid board as appropriate. We install baffles at every soffit vent. Only after the attic floor is sealed do we begin insulation installation. This sequence is what separates our results from contractors who blow insulation over leaks.
- 5
Installation, verification, and documentation. We install your specified material to the agreed depth, verify even coverage with depth probes across the attic, and run a post-work blower-door test on qualifying jobs. You receive a Documented Photo Record showing before, during, and after conditions, plus your before-and-after blower-door numbers where applicable. Your written warranty and 365-Day Done Right Promise are delivered before the crew leaves.
How Much Does Attic Insulation Cost in Converse?
A typical attic insulation top-up in Converse runs $1,800-$2,800 for a 1,500-2,500 square foot home with accessible attic space and clean existing material. Full replacement with removal, air sealing, and new blown-in insulation to R-49 typically runs $3,200-$4,800 for the same footprint. Attic batt installations in tight spaces or with mineral wool products range $2,400-$3,600. These figures include our full air-sealing protocol, baffle installation, and Documented Photo Record.
Several factors move the price within these ranges. Attic accessibility is the biggest: homes with scuttle hatches instead of pull-down stairs add labor time. Existing material condition matters too - wet or rodent-affected insulation requires HEPA-contained removal at $1.20-$1.80 per square foot. The target R-value affects material volume; jumping from R-30 to R-60 roughly doubles the material quantity. Homes in Converse’s older neighborhoods near FM 78 often need more extensive air sealing at top plates and balloon framing, which we quote line-item in your written scope.
To avoid overpaying, get any competing quote in writing and bring it to us for a Free Second Opinion. We’ll read it with you and identify what’s actually included. Some Converse contractors quote “R-38 installed” without specifying initial or settled thickness, or omit air sealing entirely. Our written scope shows exact material brand, installed depth, and R-value. Every estimate is free, and every price is flat - no hourly rates, no material upcharges, no surprises.

Frequently Asked Questions - Attic Insulation in Converse
Attic insulation is a thermal barrier installed at your ceiling plane that slows heat transfer between your conditioned living space and the unconditioned attic. In Converse, where attic temperatures reach 140°F in summer and outdoor winter lows hit the mid-20s, a properly insulated and sealed attic is the single most cost-effective improvement you can make to your home’s energy performance and HVAC lifespan. Without it, you’re paying to condition air that escapes directly into your attic.
Most attic insulation jobs in Converse are completed in one day, typically 4-6 hours for a top-up and 6-8 hours for full replacement with air sealing. Jobs requiring hazardous material removal, extensive deck repairs, or multiple attic zones may extend to a second day. Your written scope specifies the expected duration before work begins.
