Attic Insulation Replacement in Schertz, TX
Our Attic Insulation services for replacement in Schertz typically run between $1,800 and $4,200 for a standard home, depending on square footage, existing material type, and how much air sealing the attic floor needs before new insulation goes in. Most jobs are completed in a single day. Before any work starts, you receive a written price and a written scope – no surprises when the crew leaves.
If your attic insulation is more than 15 years old, has been wet, or was never adequate to begin with, replacement isn’t just about adding R-value. It’s about removing what’s failing, sealing the air leaks that insulation can’t fix on its own, and then installing the right material at the right depth. That’s the sequence we follow on every job at Topside Attic Insulation Schertz, and it’s the sequence that actually moves the needle on your energy bills.
Our full process – removal, air sealing, and new insulation installation – is covered under our Attic Insulation in Schertz service. This page focuses specifically on replacement work: what triggers it, how we do it, what it costs, and what you walk away with when we’re done. Questions before you’re ready to schedule?

When You Need Attic Insulation Replacement
Replacement is the right call when existing insulation can’t be salvaged by Attic Insulation Top-Up work. Here are the situations we see most often in Schertz homes:
- Insulation damaged by moisture or a past roof leak. Wet insulation compacts, loses R-value, and can harbor mold. Schertz sits in Bexar County’s humidity belt, and we regularly find fiberglass batts in homes near Cibolo Creek that have absorbed moisture over multiple rainy seasons. Once insulation is wet and has dried in place, it doesn’t recover its original thermal performance – it has to come out.
- Pest contamination – rodent droppings, nesting material, or evidence of wildlife activity. Attics in neighborhoods like Live Oak Estates and the older sections of Schertz-Cibolo frequently show signs of rodent activity. Contaminated insulation is a health concern and can’t be reused. Full removal, attic cleaning, and fresh installation is the only appropriate path.
- Insulation below R-30 in a home built before 2000. Texas Energy Code for new construction requires R-38 minimum in climate zone 2, which covers Schertz. Homes built in the 1980s and early 1990s often left the factory with R-19 or less in the attic. Partial top-off is sometimes possible, but if the existing material is degraded, replacement gives you a clean baseline and a documented starting point.
- Old vermiculite or deteriorating blown-in material that has settled to less than 4 inches. Settled insulation loses roughly 1 inch of depth for every decade of settling in a Schertz attic subject to summer attic temperatures that regularly exceed 140°F. When depth falls below a useful threshold and the material is old enough to be suspect, removal and replacement costs less over time than repeated top-offs.
- Post-renovation attic disturbance. HVAC replacements, ductwork repairs, and plumbing re-routes frequently scatter or compress existing insulation. If your attic was accessed for a major mechanical repair in the last few years and the crew didn’t re-level the insulation, you likely have uneven coverage with exposed joists in some areas – meaning direct heat gain into your living space.
- Persistent high utility bills despite adequate HVAC equipment. If your CPS Energy bills in summer are consistently running $250 or more on a home under 2,200 square feet, and your HVAC equipment is in good shape, the attic is usually the first place to look. A blower-door test – a pressurization reading that shows, in a single number, how much air your building envelope is losing – will tell you quickly whether the envelope is the problem.
Our Attic Insulation Replacement Process
The order of operations matters. Insulation that goes in before air sealing is done is money spent twice. Here’s exactly how we work in Schertz:
- Written price before anything is touched. Under Haven Standard Clause 1, you receive a flat price, a written scope, and a written warranty before we lift a tool. We measure the attic – square footage, joist depth, existing material type and depth, and any obvious damage or contamination. The quote you sign is the number on your invoice.
- Full removal of existing insulation. We use commercial-grade vacuum equipment to extract blown-in material or remove batt insulation by hand. Everything is bagged and hauled off-site. We don’t leave old material in corners or around HVAC equipment where it’s inconvenient to reach. A documented photo record starts here – you’ll see the attic floor condition before we proceed.
- Attic floor inspection and air sealing – completed before any new material goes in. This is the step most contractors skip or offer as an upsell. We don’t. Once the attic floor is clear, we identify and seal top plates, can light penetrations, plumbing chases, and any other bypasses using two-part spray foam or fire-rated caulk, depending on the penetration type. Air sealing is a hard prerequisite at Envelope Insulation Co. – not optional, not extra. If you want the documented blower-door reading that shows what changed, we run the test before and after this step.
- Installation of new insulation to the specified R-value. Material selection depends on your home’s construction, your budget, and the performance target we agreed on in the written scope. GreenFiber cellulose is a common choice for Schertz homes – it settles predictably, treats Texas heat well, and has a strong thermal mass for the temperature swings between November and February. Owens Corning blown fiberglass is another option where moisture management is a priority. We install to depth using calibrated equipment, and we don’t leave until the depth cards are set and the coverage matches the spec.
- Post-installation documentation and blower-door reading (on applicable jobs). Before we close the attic, we photograph depth at multiple points, confirm coverage around baffles and eave vents, and document any secondary findings – deteriorated ductwork, missing vapor barriers, damaged decking – so you have a written record even for things we didn’t do on this visit. On jobs where air sealing was performed, we provide before-and-after blower-door numbers so you can see the performance change in one figure.
- Walkthrough and 365-Day Done Right Promise. Wes Okafor or a named technician walks through the findings with you – not a summary read off a tablet, but an actual explanation of what we found, what we did, and what to watch for. The 365-Day Done Right Promise applies from this point forward: if it’s not right, we make it right, backed by the written warranty you received before work started.
Attic Insulation Replacement Pricing in Schertz
Most attic insulation replacement projects in Schertz fall into predictable price bands based on home size and scope. Here’s what the numbers look like in this market:
| Home Size (Conditioned Sq Ft) | Typical Attic Footprint | Estimated Replacement Cost |
|---|---|---|
| 1,200 – 1,600 sq ft | ~1,000 – 1,300 sq ft attic | $1,800 – $2,600 |
| 1,600 – 2,200 sq ft | ~1,300 – 1,800 sq ft attic | $2,500 – $3,400 |
| 2,200 – 3,000 sq ft | ~1,800 – 2,500 sq ft attic | $3,200 – $4,200 |
| 3,000+ sq ft / complex layout | Varies | $4,000 – $6,500+ |
These ranges include removal and disposal of existing material, attic floor air sealing of top plates and major penetrations, and new Blown-In Attic Insulation installed to R-38. They do not include remediation for active mold, structural decking repairs, or attic cleaning for heavy pest contamination – those are quoted separately after inspection if needed.
What moves the price within a range:
- Depth and type of existing material (wet fiberglass batts take longer to remove than settled cellulose)
- Number of penetrations requiring air sealing – a 1990s Schertz home with recessed can lights throughout the living space can have 30 or more cans in the attic floor
- Attic access conditions – low-pitch roofs, multiple HVAC units, and knee walls all add time
- Material selection: GreenFiber cellulose, Owens Corning blown fiberglass, and Icynene open-cell spray foam each carry different installed costs and different performance profiles
- Target R-value: R-38 is the code minimum for Schertz; some homeowners request R-49 or higher, which adds material cost but reduces long-term thermal load
Under Haven Standard Clause 1, the price you see in writing before work starts is the price you pay. If we find something during removal that changes the scope – like contaminated sheathing or a previously unknown second layer of degraded material – we stop, document it, and present a revised written price before doing anything further. We don’t invoice for work you didn’t approve.
We also offer a free second opinion on any written estimate you’ve already received. Bring us the competing quote and we’ll read it with you – line by line, if that’s useful.
FAQs – Attic Insulation Replacement
How long does attic insulation replacement take in Schertz?
Most residential attic insulation replacement jobs in Schertz are completed in one day – typically 5 to 8 hours for a home between 1,500 and 2,500 square feet. Removal takes the most time; installation is faster once the attic floor is clean and air-sealed. Larger homes, low-clearance attics, or significant pest contamination can push a job into a second day, and we’ll tell you that upfront in the written scope rather than discovering it mid-job. Call (830) 402-5240 to schedule an in-attic assessment – the written price comes after we’ve seen what’s up there, not before.
Do I need to replace all the insulation, or can you just add more on top?
Adding on top of existing material works only when what’s there is dry, uncontaminated, and still structurally intact. If the existing insulation has been wet, compressed by foot traffic, or mixed with rodent debris, topping it off traps the problem under new material rather than solving it. In our experience with Schertz homes built before 2005, full replacement is the right call more often than a simple top-off – particularly in neighborhoods like Fairways at Scenic Hills and the Schertz Parkway corridor where aging homes show consistent moisture and pest pressure. A blower-door test and attic inspection will tell you which path makes sense for your specific situation.
Is attic insulation replacement worth it financially in Schertz’s climate?
In Schertz’s climate zone 2, where cooling loads run from April through October and summer attic temperatures regularly exceed 140°F, a properly air-sealed and insulated attic is one of the highest-return improvements a homeowner can make to the building envelope. Homes that upgrade from below R-25 to R-38 or higher, with air sealing completed first, typically see measurable reductions in CPS Energy cooling costs. We document before-and-after blower-door numbers on applicable jobs so the performance change is on paper, not just estimated. If you’re weighing the investment, our Attic Insulation in Schertz page walks through the full cost-benefit picture, and you can also review our broader home services to see how attic work fits into a whole-envelope approach.
What materials do you use for attic insulation replacement in Schertz?
Material choice depends on the attic’s conditions, the homeowner’s target R-value, and any moisture or pest concerns identified during inspection. We source from Owens Corning, GreenFiber, Icynene, and other manufacturers – no proprietary product lock-in, no upselling a material because it carries a higher margin. GreenFiber cellulose is a strong default for most Schertz attics: it installs dense, handles the thermal cycling between Schertz’s summer highs and winter lows well, and is treated for pest resistance. Owens Corning blown fiberglass is a sound choice in attics with a history of moisture exposure. For attic knee walls or confined spaces where air sealing and insulation need to happen in the same application, Icynene open-cell spray foam is one option we discuss in the written scope. The spec sheet we leave with you names the material, the manufacturer, the installed depth, and the R-value achieved – so you know exactly what went in.
Why Topside Attic Insulation Schertz for Replacement Work
Wes Okafor started Topside Attic Insulation Schertz under the principles of The Haven Standard in 2016, and the operating model hasn’t changed: written price before any work starts, air sealing completed before insulation goes in, before-and-after documentation on every applicable job. Since 2016, we’ve sealed and insulated more than 9,000 homes – every one with a written price before work started and a documented photo record when we left.
Replacement work is where that sequence matters most. An attic that hasn’t been touched in 20 years will almost always have air leaks that are invisible from below and only apparent once the old insulation is out. We’ve walked attic floors in Schertz homes near the Guadalupe County line and found top plates that were essentially open to the conditioned space below – not because the builder was careless, but because no one sealed them before the original insulation went in. Removing the old material is the only way to find and fix those bypasses properly.
If you’ve had a written estimate from another contractor and want a second set of eyes on it, bring it to us. We’ll read it with you at no charge, and we’ll tell you honestly whether the scope is complete – including whether air sealing is included or listed as optional.
