We’ve sealed and insulated more than 9,000 homes since 2016, and we’ve learned that insulation problems in Seguin rarely exist in isolation. The combination of hot, humid summers, occasional hard freezes, and the limestone-heavy soils around Guadalupe County creates specific conditions: moisture migration through the attic, rodent pressure from the surrounding brushland, and settling or compression in older fiberglass batts. In neighborhoods like River Plantation, Kingsbury, and the historic districts near downtown, we’ve pulled out insulation that was doing more harm than good, trapping moisture against the deck or harboring allergens after roof leaks. We’re not here to sell you more insulation. We’re here to remove what’s failing, seal the envelope properly, and install material that actually performs in Seguin’s climate.
What Our Insulation Removal & Replacement Service Includes
Attic Insulation Removal
Attic insulation removal is the complete extraction of existing material from your attic floor, knee walls, or vaulted ceilings to prepare for proper air sealing and new insulation. In Seguin, we most often remove compressed fiberglass batts that have settled below their labeled R-value, or blown-in cellulose that has stratified and developed voids near the eaves. Our crews use commercial-grade vacuums with HEPA filtration and bag the material directly to avoid contaminating your living space. We document the depth, condition, and any signs of moisture damage or pest activity in your photo record before anything new goes in.
Contaminated Insulation Removal
Contaminated insulation removal addresses material compromised by water intrusion, mold, rodent droppings, or fire/smoke damage. Seguin’s position between the Guadalupe River and the rolling prairie means humidity spikes and occasional flooding that can saturate attic insulation, especially in homes near the river basin or in lower-lying areas of McQueeney and Marion. We treat this as a health and safety issue, not a cosmetic one. Our crews wear full PPE, use negative air machines to control spore and particulate migration, and dispose of contaminated material according to Texas Commission on Environmental Quality guidelines. You’ll receive photos of the affected areas and confirmation that the substrate is clean and dry before replacement begins.
Vermiculite & Old Insulation Removal
Vermiculite and old insulation removal requires special handling, particularly for the vermiculite mined from Libby, Montana, which may contain asbestos. Homes built in Seguin before 1990, especially in the older neighborhoods around Court Street and Weinert Street, are the most likely candidates. We do not disturb vermiculite without third-party asbestos testing, and we maintain relationships with certified abatement contractors for cases that require it. For non-vermiculite old insulation, such as rock wool or early fiberglass from the 1960s and 1970s, we assess whether full removal is necessary or whether strategic supplementation with air sealing and new material is the more cost-effective path. Either way, you get a written scope with the rationale before we start.
Insulation Replacement
Insulation replacement is the installation of new material after removal and air sealing are complete. Under The Haven Standard, we never install new insulation over an unsealed attic floor. We seal top plates, plumbing and electrical penetrations, can lights, and chimney chases first, then verify our work with a blower-door test, a pressurization reading that shows, in one number, how much conditioned air your building envelope was losing. Only then do we install your chosen replacement material, whether that’s blown-in fiberglass, dense-pack cellulose, open-cell spray foam, or a hybrid system. On applicable jobs, we provide before-and-after blower-door numbers so you can verify the performance change you paid for.

Brands We Service for Insulation Removal & Replacement
We’ve worked extensively with Owens Corning systems, including their ProPink Loosefill and AttiCat blown-in fiberglass products. Their material performs well in Seguin’s heat, and we know how to achieve consistent coverage depth across irregular attic framing without the thin spots that create thermal bypasses. We’ve also installed hundreds of jobs using Demilec open-cell spray foam, particularly in vaulted ceilings and conditioned attics where air impermeability matters more than bulk R-value alone. Demilec’s water-blown formulations handle our humidity cycles without the odor issues we’ve seen in some legacy products.
For homeowners seeking recycled-content options, GreenFiber cellulose is our go-to for dense-pack wall cavities and attic floors where we want the material to settle into every gap. We’ve also used Icynene in hybrid applications, pairing their open-cell foam on the roof deck with vented attic strategies in older Seguin homes where full conversion isn’t practical. Whether you have a preference for one of these brands or you’re starting from scratch, we’ll specify the right product for your assembly, not the one that moves fastest from our warehouse.
Before
AfterSigns You Need Insulation Removal & Replacement Right Now
- Your energy bills have climbed without a change in usage. In Seguin, a well-sealed and insulated home should hold its temperature through our summer peaks. If your HVAC is running longer cycles to maintain the same setpoint, degraded insulation is often the culprit. We’ve measured attic floors in River Crossing and Willow Creek where the effective R-value had dropped by 40% due to compression and moisture.
- You smell mustiness or see staining on your ceilings. Insulation that has absorbed moisture acts like a sponge against your drywall. In Guadalupe County’s humid climate, this can progress from odor to visible mold in a single season. The insulation needs to come out so the deck can dry and the leak source can be found.
- You’re finding rodent droppings or nesting material in the attic. Roof rats and mice are active year-round in Seguin’s brushy margins, and once they’re in your attic, the insulation becomes their bedding. We remove the contaminated material, seal entry points with rodent-proof materials, and replace with clean insulation after documenting the exclusion work.
- Your home was built before 1990 and has never had the insulation addressed. Vermiculite, early fiberglass with formaldehyde binders, and settling rock wool are common in Seguin’s older housing stock. Even if the material tests clean, it rarely meets current performance standards and often lacks the air barrier integration that modern building science requires.
- You’re planning a roof replacement or major HVAC upgrade. These are the optimal moments to address insulation, with the attic fully accessible and the long-term payback clear. We’ve coordinated with roofers in Seguin to sequence removal during tear-off, then return for air sealing and replacement before the new roof goes on, avoiding double mobilization costs.
Our Insulation Removal & Replacement Process - Step by Step
- 1
On-site assessment and blower-door baseline. We arrive at the scheduled time, introduce the named technician, and run a blower-door test to quantify your home’s current air leakage rate in CFM50, cubic feet per minute at 50 Pascals of pressure. We photograph the existing insulation condition, measure depths, and identify any safety hazards like exposed wiring or active leaks. You receive a written price with a flat scope before we leave, not a range that shifts later.
- 2
Containment and removal. We isolate the attic access with plastic sheeting and run HEPA-filtered negative air machines to protect your living space. Material is vacuumed or bagged directly, never dragged through your hallway. Contaminated loads are segregated and disposed of per TCEQ requirements. The photo record documents every stage.
- 3
Air sealing of the attic floor and penetrations. This is the step that separates our work from a standard insulation contractor. We seal top plates, wire and pipe penetrations, can light housings, bathroom fan boots, and chimney chases with appropriate materials: fire-rated caulk, metal flashing, rigid foam, or specialized gaskets. In Seguin’s climate, this matters as much as the insulation itself. A leaky R-38 performs like an R-19 or worse.
- 4
Blower-door verification and insulation installation. We run the blower-door again to confirm we’ve hit our target reduction, typically 20-40% improvement depending on the starting condition. Only then do we install your specified replacement material to the designed depth or coverage, using rulers, depth markers, and thermal imaging to verify consistency. No guesswork, no thin spots over the garage or master bedroom that show up on the next infrared scan.
- 5
Final documentation and walkthrough. You receive your Documented Photo Record, the before-and-after blower-door numbers if applicable, and a written warranty under our 365-Day Done Right Promise. We review what was done, what to expect from your HVAC system going forward, and how to reach us if anything doesn’t perform as specified. The technician’s name and direct contact are on your paperwork.
How Much Does Insulation Removal & Replacement Cost in Seguin?
Most attic Insulation Removal & Replacement cost guide jobs in Seguin run between $2,200 and $4,800 for a home in the 1,500-2,500 square foot range. A straightforward removal of settled blown-in fiberglass, with moderate air sealing and replacement with new blown-in material, typically lands in the $2,200-$3,200 band. Projects involving vermiculite testing and potential abatement coordination, extensive rodent damage remediation, or full spray foam conversion on a complex roofline can extend to $5,500-$7,500.
What moves the price: attic square footage and accessibility, the type and volume of material to be removed, whether contamination requires special handling, the extent of air sealing needed, and your choice of replacement material. Open-cell spray foam runs higher per square foot than blown fiberglass or cellulose, but it also provides the air barrier in one step. A conditioned attic conversion with closed-cell foam on the roof deck is a different project entirely, and we price those separately with full assembly details.
How to avoid overpaying: get a written scope that specifies removal depth, air sealing locations, replacement R-value or thickness, and material brand. Vague quotes that say “insulate attic” without these details leave room for corner-cutting. We provide a Free Second Opinion on any written estimate, and we’ll read it with you line by line. Our written price includes all labor, material, disposal, the blower-door testing, and your photo record. No line-item surprises when the crew is already in your attic.
