Envelope Insulation Co. has been independently owned and operated under The Haven Standard since 2016. In that time, we’ve sealed and insulated more than 9,000 homes – every single one with a written scope before work began and a documented record when the crew left. Wes Okafor leads the team, and if you’ve done any research into attic insulation contractors in this part of Texas, you’ll notice something different about how we approach the work: air sealing comes first, always, before a single cubic foot of insulation goes in.
That’s not a minor procedural detail. In Converse and the surrounding Bexar County suburbs, attic floors are often full of unsealed top plates, open can-light penetrations, and HVAC boot gaps that funnel conditioned air straight into an unconditioned attic. Blowing insulation over those gaps adds R-value on paper while your energy bills tell a different story. We seal first – top plates, can lights, plumbing and electrical penetrations – and we document the result with before-and-after blower-door readings: a pressurization measurement that shows, in a single figure, exactly how much conditioned air your building envelope was losing before we arrived and after we finished.
Most homeowners in Converse who contact us after a high-summer energy bill find attic floors sitting at R-19 or below – well short of the R-38 to R-60 range that performs correctly in this climate. Some have insulation that was adequate when installed but has compressed or settled over a decade of San Antonio-area heat cycles. We assess what’s there, give you a written price to address it, and let the blower-door numbers speak for the result.

Fast, Local Attic Insulation
Most homeowners who call (830) 420-0953 are scheduled within one to two business days. For situations where an attic is completely uninsulated – or where insulation has been displaced by pest activity or a recent roof repair – we work to get crews out as quickly as the written scope for Attic Insulation Replacement can be prepared and confirmed.
A live person answers every call, 24 hours a day, seven days a week. There are no voicemail loops, no callback windows measured in business days. Under the Haven Standard, you receive a named technician and a text when they’re on the way. The written price you agreed to before the job started is the price on the invoice when the crew leaves – flat, no line-item surprises added at the end.
We serve Converse and the surrounding communities throughout northeast Bexar County and into Guadalupe County. Whether your home is in an older subdivision off Judson Road or a newer build in one of the developments along FM 1518, the same process applies: written scope, air sealing before insulation, documented photo record, and blower-door readings on applicable jobs.
Areas We Cover
Topside Attic Insulation Converse serves homeowners throughout Converse and the immediately surrounding communities. If your home is in Universal City, Live Oak, Windcrest, Schertz, Selma, Cibolo, or Kirby, we cover your area. These northeast San Antonio suburbs share similar housing stock – many homes built between the late 1990s and 2015 with fiberglass batt or blown-in fiberglass that has settled significantly – and the same South-Central Texas climate conditions that make attic air sealing worth doing before the insulation ever goes in.
In Schertz and Cibolo particularly, we see a lot of homes in the 2,200-to-3,400-square-foot range where the original attic insulation was installed to code minimums and never touched again. Those code minimums from 15 years ago don’t match today’s energy performance expectations, and they definitely don’t account for can-light and top-plate air leakage that can account for a larger share of cooling load than the insulation R-value itself.
If you’re unsure whether your address falls inside our service area, call (830) 420-0953. A live person will confirm coverage and can begin building your written estimate on the same call.
Before
AfterWhat to Expect: The Process from First Call to Final Photo
Step 1: Written Price Before Anything Else
Under Haven Standard Clause 1, no work starts without a flat, written price, a written scope describing exactly what will be done, and a written warranty. This is not a verbal estimate that gets adjusted when the crew arrives. You see the number, you agree to it, and that is the number on the final invoice.
Step 2: Air Sealing First
Before any insulation goes in, the attic floor gets sealed. Top plates – the framing gaps at the top of interior walls – get foam. Can lights get sealed with fire-rated materials. HVAC boot penetrations, plumbing stacks, and electrical chases all get addressed. In Converse homes built in the 1990s and early 2000s, it’s common to find 30 to 50 individual penetrations that have never been touched. We document each one.
Step 3: Blower-Door Test (Applicable Jobs)
On applicable jobs, we run a blower-door test before sealing and again after. The reading is expressed in CFM50 – cubic feet per minute of air movement at 50 pascals of pressure – and it gives you an objective, third-party-style number showing the performance change. A home reading 4,800 CFM50 before sealing and 2,400 after has cut its air exchange rate roughly in half. That’s a number you can verify, not a feeling we’re asking you to trust.
Step 4: Insulation Installation
We work with materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The right material depends on your attic geometry, your existing conditions, and your performance goals – not on what we happen to have more of on the truck. Most Converse attics in the 1,800-to-2,600-square-foot range are candidates for Blown-In Attic Insulation with cellulose or fiberglass to bring total depth to R-38 minimum, often R-49 to R-60 depending on the home.
Step 5: Documented Photo Record
When the crew leaves, you receive a documented photo record of the completed work – penetrations sealed, insulation depth at multiple measurement points, and any pre-existing conditions we found. This is included on every job, not available on request. You know what was done because you have photos showing it.
How Much Does Attic Insulation Cost Near Converse, TX?

Call (830) 420-0953 to confirm your address and start building a written estimate.
How much will attic insulation cost for my home?
A complete air sealing and Attic Insulation Top-Up job in a typical Converse-area home – 1,500 to 2,500 square feet of attic floor – generally runs between $1,400 and $3,200. Insulation removal and replacement, or spray foam applications at the roof deck, run higher. The only number that matters is your flat written price, which you receive before any work starts. Call (830) 420-0953 to get that number – no vague ranges, no “it depends” without explanation.
Can you come after hours or on weekends?
A live person answers calls at (830) 420-0953 24 hours a day, seven days a week – no voicemail, no on-call delay measured in business days. Weekend and after-hours scheduling is handled on a job-by-job basis. Calling outside normal business hours does not push your job to the back of the queue – it gets you a real conversation and a real answer about availability.
Do you give free second opinions on competing estimates?
Yes. If you have a written estimate from another contractor, bring it to us. Wes Okafor and the team will read it with you line by line – materials specified, scope described, air sealing included or not – and give you a written price for comparison. A competing quote that doesn’t include attic air sealing is comparing apples to a partial job. We’ll show you exactly where the difference is. Call (830) 420-0953 to set that up.
Why Air Sealing Matters More Than R-Value Alone in Converse
Converse sits in IECC Climate Zone 2, which means long, hot summers with sustained temperatures above 95 degrees and a cooling load that runs from April into October most years. The attic above a code-built 2005 home in Converse can reach 140 to 160 degrees on a July afternoon. At those temperatures, every unsealed penetration in the attic floor is a direct pathway for superheated air to work its way into the conditioned space below.
Adding R-30 or R-38 of blown-in insulation slows conductive heat transfer through the floor assembly – that’s what R-value measures. But it does nothing to stop convective air movement through a gap around a can light or a top plate. In homes we’ve tested in the Judson ISD attendance zone and in the older sections of Universal City, blower-door readings before air sealing often run 4,000 to 6,000 CFM50 or higher. After sealing the attic floor penetrations alone – before touching the insulation – readings drop by 25 to 45 percent in many cases.
That’s why the order of operations matters. Seal first, then insulate. The blower-door numbers don’t lie, and you’ll have yours in writing when we’re done.
The 365-Day Done Right Promise
Every job Topside Attic Insulation Converse completes is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right. This isn’t a verbal commitment. You receive the written warranty before work starts, as part of the scope document. If insulation settles unevenly, if a sealed penetration opens up, if the blower-door numbers don’t reflect what was promised – call us. The promise applies for 365 days from the completion date, no exceptions.
This is the Haven Standard approach: evidence first, documentation always, promises in writing before they become relevant.
Get a Written Price for Your Converse Home
If you’re in Converse, TX or any of the surrounding communities – Universal City, Live Oak, Windcrest, Schertz, Selma, Cibolo, or Kirby – and your attic hasn’t been assessed in the last five years, there’s a reasonable chance you’re running below the R-38 to R-49 threshold that performs correctly in this climate. There’s also a reasonable chance your attic floor has unsealed penetrations that no amount of additional insulation will fix on its own.
The starting point is a written price with a complete scope. Call (830) 420-0953 – a live person will pick up, confirm your area, and start building your estimate. No work starts until you have that price in writing, and the 365-Day Done Right Promise covers everything after.

What Our 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."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R."They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."
- Harriet N.
