Frequently Asked Questions - Insulation in Schertz, TX
We're the local team behind Topside Attic Insulation here in Schertz, and these are the questions we actually get from homeowners in Cibolo, Universal City, and across the I-35 corridor. Every answer is drawn from what we've seen in attics here since we opened this branch.
Pricing & Cost FAQs
Most attic insulation jobs in Schertz run between $1,800 and $4,200 for a typical 1,800-2,400 square foot home, depending on whether we're adding to existing material or starting fresh after removal. The bigger variable is air sealing, which we won't skip - sealing top plates, can lights, and chase openings in a Schertz attic usually adds $800-$1,600 but is what actually changes your blower-door number. We publish the price range on the page because Clause 1 of our Haven Standard says you'll have a flat, written price before anyone starts. Call (830) 402-5240 for a free written estimate scoped to your attic.
Adding insulation over old material costs less upfront, but it's rarely the better value in Schertz's climate. Existing insulation in our area is often compressed, displaced by previous work, or contaminated with rodent activity we see frequently near the Cibolo Creek watershed. Removal and replacement lets us seal the attic floor properly first, which is the whole point of the Topside approach. We'll show you photos of what we find and quote both paths so you can decide with real numbers. Call (830) 402-5240 for a free written estimate.
Low quotes usually skip air sealing, use lower-grade material, or omit the prep work that makes insulation perform. In Schertz's hot, humid summers, blown-in fiberglass over unsealed top plates is essentially a filter for your air conditioning. We document what we find, seal what we can measure, and show you the before-and-after blower-door reading so you know what you bought. The Haven Standard requires a written scope and price before work starts - no surprises, no scope creep. Call (830) 402-5240 to compare apples to apples.
CPS Energy customers in our service area may qualify for rebates through the Home Energy Efficiency Program, though availability changes seasonally. We don't promise specific rebate amounts because program terms shift, but we document every job with photos and blower-door readings that satisfy typical program requirements. Our written estimate notes whether your project profile aligns with current programs. Call (830) 402-5240 and we'll point you toward the latest information while we scope your job.
Service & Process FAQs
We start in your attic hatch with a flashlight and a camera, documenting insulation depth, condition, and visible air leaks. Then we run a blower-door test if your home can be depressurized safely, which gives us a baseline CFM50 reading - the actual leakage rate. In Schertz homes built between 1980 and 2010, we regularly find unsealed can lights, open chase walls, and top plates with gaps that explain why the second floor won't cool. You'll receive photos, the blower-door number, and a written scope with a flat price before we schedule any work.
A standard air-sealing and insulation job takes one to two days for most Schertz homes. Day one is prep, sealing, and material placement; day two is verification, cleanup, and a final blower-door test to confirm we hit the target. Older homes in Terrell Hills or Alamo Heights with complex rooflines or limited attic access sometimes need a third day. We give you a real schedule window, a named technician, and a text when they're on the way - that's Clause 2 of the Haven Standard.
You don't need to leave, but you'll want to stay out of the work zone. Our crews seal off attic access points with plastic sheeting and run negative air machines when removing old material. The blower-door test requires all exterior doors and windows to be closed, so plan around that 30-minute window. We've worked around home offices in Live Oak, napping toddlers in Converse, and dogs who need yard access in Selma - just tell us your constraints when we schedule.
Clear a path to the attic hatch and remove anything stored directly under it. If you have valuables in the attic, move them or tell us - we work around what we can, but the blower-door fan and hose routing need floor space. In Schertz's older neighborhoods like Windcrest and Kirby, we've found family photos, military records, and holiday decorations that homeowners forgot were up there. We photograph everything as-found, but we don't move heavy items without prior discussion.
Peek through your attic hatch with a ruler. In Schertz's climate zone, the Department of Energy recommends R-38 to R-60 for attics, which is 12 to 18 inches of blown fiberglass or 10 to 14 inches of cellulose depending on the product. But depth alone doesn't tell the story - we regularly find 14 inches of material that's been compressed by storage, disturbed by wiring work, or bridged over unsealed gaps that bypass it entirely. The blower-door test reveals what the ruler cannot.
Brands & Parts FAQs
We specify Owens Corning fiberglass and GreenFiber cellulose for most Schertz attics, choosing between them based on your home's conditions and your priorities. Owens Corning holds its loft well in our humid summers and is what we use when we need consistent coverage in irregular framing. GreenFiber's dense-pack cellulose performs excellently for air sealing and sound dampening, which matters for homes near I-35 or under flight paths. We don't stock everything - we stock what works here.
Spray foam, like the Icynene and Demilec products we use for specific applications, creates an air barrier and insulation in one step and is excellent for rim joists, crawl spaces, and complex rooflines. Blown-in fiberglass or cellulose is what we use for most attic floors because it's cost-effective, inspectable, and can be added to later if you finish a room. In Schertz's climate, the critical factor isn't the material - it's whether the attic floor was sealed first. We publish what we find and recommend what the evidence supports.
We can, but we won't automatically. Matching old fiberglass with new fiberglass is common, but if your existing material is contaminated, compressed, or performing poorly, we'll show you why and recommend the better path. In homes near the Cibolo Creek floodplain, we've found insulation that looked fine from the hatch but was moisture-compromised underneath. Our estimate includes photos of what we found, not what we felt about it - you decide with evidence.
Licensing & Insurance FAQs
Every professional working under our name is required to hold the license and insurance Texas requires for the work they're performing. We carry general liability and workers' compensation coverage, and our license numbers are available on request. The Haven Standard's Clause 3 - Verified crews - means background-checked technicians with their credentials documented. This isn't a guarantee we make; it's a requirement we enforce.
Permit requirements depend on scope. Simple insulation overlay in an unfinished attic typically doesn't trigger a permit in Schertz or Guadalupe County, but removal of existing material, changes to ventilation, or spray foam application may. We handle permit research as part of our written estimate and pull what's required. If a competitor tells you permits are never needed, that's a red flag - we've seen unpermitted spray foam jobs in New Braunfels that created moisture traps and code headaches for the next owner.
The Haven Standard is the five-clause framework every Topside Attic Insulation branch works to, developed from the 9,000-plus homes sealed and insulated since the parent brand's founding in 2016. Clause 1: Have it in writing - flat price, written scope, written warranty before work starts. Clause 2: Arrive on schedule - real window, named tech, text on the way. Clause 3: Verified crews - licensed, insured, background-checked. Clause 4: Evidence on every job - photos and readings of what we found. Clause 5: No surprises - no door upsell, no scope creep, no "while we're in here." You receive documentation of each clause at job completion.
Emergency & Response FAQs
We schedule inspections as soon as our calendar allows, typically within two to five business days depending on season and current workload. We're not an emergency service - insulation problems develop over months and years, not hours - but we do prioritize homes with active roof leaks or HVAC failure where insulation is part of the recovery. Our hours are Monday through Friday 7:00 AM to 8:00 PM, Saturday and Sunday 7:00 AM to 7:30 PM. Call (830) 402-5240 and our live coordinator will find the first available slot.
Stop the water first, then call us. Wet insulation is a mold risk in Schertz's humidity, and fiberglass that has been saturated loses its R-value permanently. We don't install over wet material, and we won't give you a scope until the roof is repaired and the attic is dry. We've worked with homeowners in Cibolo and Selma who tried to rush this step - the insulation had to come back out six months later. Document the damage for insurance, fix the source, then we'll assess what needs replacement.
We're available Saturday and Sunday 7:00 AM to 7:30 PM for inspections and most installation work. Weekend slots fill faster, especially in spring and fall when homeowners across Universal City and Converse are tackling energy bills. We don't charge weekend premiums - the written estimate is the written estimate, regardless of day. Call (830) 402-5240 to check availability; our coordinator will text confirmation with your technician's name and window.
Warranty & Guarantees FAQs
Our workmanship warranty covers installation quality for the period specified in your written estimate, and material warranties come from the manufacturer - Owens Corning and GreenFiber each have their own terms we pass through unchanged. The Haven Standard requires that warranty terms are in writing before work starts, not promised verbally at the door. What we guarantee above all is the documentation: photos of what we found, the blower-door number before and after, and a record you can reference if you sell your home or need service later.
We review the job documentation together. If the blower-door number improved but bills didn't, the issue is usually elsewhere - HVAC sizing, duct leakage, or thermostat habits - and we'll show you what the data says. If we missed a seal point or under-specified material, we fix it under warranty. In ten years of this brand's operation, the rare callback has almost always traced to a change in the home after we left - a new roof penetration, a bathroom fan disconnected, a homeowner storing boxes on the insulation. The documentation protects both of us.
Your documentation transfers with the home. The next owner sees the before photos, the blower-door reading, the scope, and the warranty terms - it's a selling point we've seen used in Schertz, Live Oak, and Alamo Heights listings. The workmanship warranty itself is tied to the original customer and specified period, but the evidence of professional work remains. We've had realtors call us to verify job details for closing; we keep records and can produce them on request.
Clause 5 of the Haven Standard is No surprises - and that includes the final walkthrough. You sign off only after reviewing the photos, the blower-door improvement, and the completed scope against the written estimate. If something doesn't match, we correct it before we leave. We don't use "satisfaction guarantee" as vague marketing language; we use a documented process that prevents the need for one. The proof is in the paperwork we leave behind.
