We know Converse’s housing stock because we’ve crawled through hundreds of its attics. The slab-on-grade tract homes near the Randolph corridor, the low-pitch hip roofs around FM 78, the 1990s builds tucked between Converse Parkway and Gibbs Sprawl - we’ve measured the settled fiberglass, documented the blower-door readings, and written the scopes. Our crews dispatch from the San Antonio office and carry the baffles, soffit vents, and blown-in equipment needed for Converse’s specific retrofit conditions. No callback windows. No “we’ll check availability.”

Why Topside Attic Insulation Canyon Lake Is Converse’s Preferred Attic Insulation Company

We’ve sealed and insulated more than 9,000 homes since 2016, and a disproportionate share of those have been in Converse. The reason is straightforward: this market has a specific problem - original 1980s blown-in fiberglass settling to R-15 or below in rental properties that cycle through military families on short PCS assignments - and we publish the before-and-after blower-door numbers that prove whether the fix actually worked.

Our Converse customers leave three-star reviews when we find something unexpected in the attic. They leave five-star reviews when we document it with photos, explain it in the written scope, and fix it under the 365-Day Done Right Promise. Both review types are public. We don’t filter them.

Response time to Converse neighborhoods averages 35 minutes from dispatch to arrival for scheduled inspections. Emergency calls - attics with active leaks, failed HVAC in 100°F heat - get same-day response. The crew that shows up is background-checked, uniformed, and named in the text you receive when they’re en route.

Local knowledge matters here in a way it doesn’t in newer suburbs. Converse’s 1978-2000 tract homes have 2×4 walls, vented attics with minimal soffit intake, and top plates that were never sealed during original construction. A technician who hasn’t worked this housing stock will blow insulation over unsealed penetrations and call the job complete. We don’t. Our Attic Insulation protocol requires air sealing before any insulation touches the attic floor - that’s Haven Standard Clause 1, and it’s non-negotiable.

Our Attic Insulation Services in Converse

Blown-In Attic Insulation

Blown-in fiberglass or cellulose is the right fix for most Converse attics because the existing material has settled, compressed, or been disrupted by HVAC work. We use Johns Manville, Knauf, and GreenFiber products - no proprietary lock-in - and we don’t blow until the top plates, can lights, and wire penetrations are sealed. In a typical 1,600-square-foot Converse ranch near Woodlake, blown-in to R-38 runs $2,200-$3,800 including air sealing. The blower-door test before and after shows the actual leakage reduction, not just the added inches.

Attic Batt Insulation

Batt insulation - pre-cut fiberglass or mineral wool panels - makes sense in Converse homes with walkable attic decks and minimal HVAC obstructions. Rockwool batts handle the San Antonio basin’s 150°F peak attic temperatures without degrading. We see batt jobs most often in Converse’s newer construction, post-2000 builds near Cibolo Creek, where the original insulation was installed to a higher standard and only needs targeted replacement. Batt installation in these homes typically ranges $1,800-$3,200.

Attic Insulation Top-Up

This is the dominant service in Converse, and for a specific reason. The original 1980s blown-in fiberglass in Randolph-era rentals has settled to R-15 or below - sometimes R-11 - and the deficit goes undetected because short-term military tenants rarely escalate high utility bills to out-of-area landlords. We pull the attic hatch, measure what’s there, and top to R-38 with blown cellulose or fiberglass after sealing air leaks. Most Converse top-ups run $1,200-$2,400. The work takes one day. The blower-door documentation goes to the homeowner before the crew leaves.

Attic Insulation Replacement

Full replacement is necessary when existing insulation is contaminated, water-damaged, or so compressed that topping up would bury the problem. In Converse, we see this most often after roof leaks near the end of a shingle’s life, or when rodent activity has rendered fiberglass unusable. We remove, dispose, clean the deck, seal all penetrations, and reinstall to modern R-38 minimums. Replacement jobs in Converse’s typical 1,400-1,800 square foot homes range $3,200-$5,500 depending on access difficulty and contamination level.

Attic Baffles & Ventilation Prep

Converse’s 1978-2000 tract homes were built with undersized soffit vents that choke intake airflow. Without baffles - the cardboard or foam channels that keep insulation from blocking the vent - a top-up traps hot attic air against the new material and the cooling load barely moves. We install baffles at every soffit vent before blowing insulation, ensuring the attic breathes. This step is included in our standard scope, not sold as an add-on. In low-pitch hip roofs common near Live Oak Road, this prep is essential; the crew belly-crawls the ridge line, and crushing existing batts while routing around flex duct is a real risk without proper ventilation planning.

Trusted Brands We Service in Converse

We source from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no exclusive supplier agreements that limit what’s right for your home. For Converse’s specific conditions, we typically specify Knauf EcoFill blown fiberglass or GreenFiber cellulose for top-ups, and Rockwool batts where fire resistance and high-temperature stability matter. We stock local inventory for Converse jobs, so material delays don’t push your start date. The brand names go in the written scope before work starts, not after.

Common Attic Insulation Problems We See in Converse Homes

• Settled R-15 fiberglass hiding in plain sight. Original 1980s blown-in has compressed to half its labeled R-value or worse, and decades of short-PCS military tenant turnover mean no one escalated the utility bills to the landlord. We find this during pre-sale inspections, when the deficit finally surfaces.
• Crushed batts under flex duct in low-pitch hip roofs. Converse’s slab-on-grade tract homes have almost no walkable deck. Crews - ours included - belly-crawl the ridge line, and without careful routing around HVAC lines, existing insulation gets flattened to near-zero effectiveness.
• Unsealed top plates bleeding 150°F attic air into conditioned space. The pressure boundary was never completed during original construction. Open chases let superheated attic air straight into the return, so the homeowner blames the insulation layer for what is actually an air-sealing failure.
• Blocked soffit vents turning attics into solar ovens. Undersized 1980s soffit vents, often painted over or insulated shut, eliminate the intake airflow that vented attics require. Without baffles and vent clearance, new R-38 material sits in a stagnant 150°F environment and underperforms by 30% or more.
