Trusted Insulation Removal & Replacement for Tustin Homeowners
Our Insulation Removal & Replacement in Tustin typically costs $1,800-$4,500 for a standard attic, with most jobs completed in one to two days. We remove old, contaminated, or underperforming insulation and install new material only after air sealing the attic floor, which is why our blower-door numbers improve on every job. Call (657) 286-7673 for a written price before any work starts - that’s Haven Standard Clause 1, no exceptions.
We’ve sealed and insulated more than 9,000 homes since 2016, and a growing share of our work in Tustin starts with removal. The 1980s and 1990s builds in neighborhoods like Tustin Ranch and Laurelwood often have original fiberglass batts that have settled, been disturbed by rodents, or absorbed moisture from roof leaks that were fixed years ago but never cleaned up. Newer homes in Columbus Grove and Peters Canyon can have insulation that was installed over unsealed top plates and can-light penetrations - the thermal equivalent of wearing a sweater with the zipper open. We don’t add new insulation until we’ve sealed what the old crew skipped. Every job ends with a Documented Photo Record and, on applicable work, before-and-after blower-door readings you can keep.
Our crew serves Tustin from the 92780 and 92782 zip codes out to the city limits near Irvine Boulevard and Jamboree Road. Same-day appointments are often available, and a live person answers calls 24/7 - no voicemail loops, no callback windows measured in business days.
What Our Insulation Removal & Replacement Service Includes
Attic Insulation Removal
Attic insulation removal is the complete extraction of existing material - whether fiberglass batts, blown-in cellulose, or loose-fill mineral wool - down to the drywall or plank ceiling below. In Tustin, we perform this service most often for homeowners who are remodeling, re-roofing, or correcting installation errors from prior contractors. Our crew uses commercial vacuums with HEPA filtration and 4-inch hoses routed directly outside, so no debris travels through your living space. We document the empty attic with photos before any new work begins.

Contaminated Insulation Removal
Contaminated insulation removal addresses material that has been compromised by rodent droppings, urine, mold, or water damage - conditions that make the attic a source of indoor air quality problems rather than a thermal buffer. Tustin’s warm, dry climate can actually preserve rodent waste for years without obvious odor, which is why we inspect with moisture meters and UV lights, not just our eyes. We follow Cal/OSHA guidelines for PPE and disposal, bagging contaminated material in sealed 6-mil poly before it leaves the attic. After removal, we sanitize affected surfaces and can install rodent-proofing at the same time.

Vermiculite & Old Insulation Removal
Vermiculite insulation removal requires special handling because much of the vermiculite mined before 1990 came from Libby, Montana, and contains asbestos. If your Tustin home was built between the 1940s and 1980s and has pebbly, silver-gold granules in the attic, we assume it’s hazardous until lab testing proves otherwise. We work with certified environmental consultants for sampling, and if asbestos is present, we coordinate abatement with a licensed hazmat contractor - we don’t cut corners on this. For non-hazardous old insulation (pre-1970s mineral wool, early fiberglass, or degraded cellulose), we remove and dispose under standard CalRecycle protocols, with documentation you can file for your records.

Insulation Replacement
Insulation replacement is what happens after removal, but only after we’ve sealed the attic floor - top plates, wire and pipe penetrations, can lights, chimney chases, and the attic hatch. We source replacement materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, selecting based on your roof geometry, duct location, and whether you use the attic for storage. In Tustin’s climate, where summer attic temperatures exceed 140°F, we often recommend blown-in fiberglass or mineral wool for cost-effectiveness, or open-cell spray foam when the HVAC system lives in the attic and needs every CFM of conditioned air kept inside. The replacement ends with a final blower-door test when air sealing was part of the scope, so you have a number that proves the improvement.

Signs You Need Insulation Removal & Replacement Right Now

- Uneven temperatures room to room. If your master bedroom in Tustin Ranch runs 8°F warmer than the hallway in July, or your north-facing rooms never warm up in January, the insulation may have shifted, settled, or been installed without air sealing in the first place. We measure this with an infrared camera during our free estimate, so you see the gaps before we quote.
- Dust or odors from ceiling vents or attic hatches. Fiberglass particles, rodent waste, or mold spores can migrate through recessed light fixtures, whole-house fan louvers, or poorly sealed duct boots. If you smell something musty when the HVAC cycles on, or if your return air filter loads up faster than the manufacturer interval, the attic is likely the source.
- Visible pest activity or droppings in the attic. Roof rats are common in older Tustin neighborhoods with mature fruit trees, and they tunnel through insulation to nest. Even after extermination, the contaminated material remains a health hazard and an attractant for the next colony. Removal and sanitizing breaks the cycle.
- Water stains on the ceiling or attic sheathing. A roof leak that was patched two years ago may have soaked insulation that never dried out in Tustin’s coastal humidity. Wet insulation loses R-value, grows mold, and corrodes nail heads and electrical boxes. We probe with moisture meters to find hidden saturation.
- Energy bills that climbed without a rate increase. If your Southern California Edison bill jumped 20% or more and your usage patterns haven’t changed, the building envelope is the first place to look. Insulation compresses, air leaks develop at new penetrations, and what worked in 2010 doesn’t work in 2025.
Before
AfterOur Insulation Removal & Replacement Process - Step by Step
- 1
Written estimate with scope and price. We start every Tustin job with a full attic inspection, infrared scan, and blower-door test when air sealing is part of the project. You receive a written price, a written scope, and a written warranty before anyone lifts a tool - Haven Standard Clause 1. No surprises, no “we found more once we got up there” add-ons.
- 2
Prep and protection. Our crew lays protective sheeting from the front door to the attic access, seals the work area with ZipWall barriers if needed, and sets up negative-air HEPA vacuums. Background-checked, uniformed technicians wear photo ID badges - you’ll get a text with their name and ETA when they’re on the way.
- 3
Removal and disposal. We extract old insulation using commercial vacuum equipment routed outside to a contained trailer or bagging station. Contaminated material is double-bagged in 6-mil poly and disposed of per California DTSC regulations. We photograph the empty attic deck for your Documented Photo Record.
- 4
Air sealing and repair. Before any new insulation goes in, we seal top plates, electrical penetrations, can lights, bath fan housings, and the attic hatch with fire-rated caulk, spray foam, or rigid baffles as appropriate. This is the step most Tustin contractors skip - and the reason our blower-door numbers drop by 30-50% on typical jobs.
- 5
Replacement, testing, and documentation. New insulation is installed to the specified depth and density, with ruler markers visible for future inspection. On air-sealing jobs, we run a final blower-door test and publish the before-and-after CFM50 reading on your invoice. You leave with photos, test results, and a 365-Day Done Right Promise in writing.
How Much Does Insulation Removal & Replacement Cost in Tustin?

A typical attic Insulation Removal & Replacement cost guide shows Tustin jobs run $2,800-$4,500 for a 1,500-square-foot home with standard fiberglass or cellulose replacement, including air sealing of the attic floor. Smaller jobs - partial removal over a garage or a single contaminated section - can run $1,200-$2,200. Vermiculite removal with asbestos abatement coordination starts around $5,500 and scales with attic square footage and hazmat complexity. Spray foam replacement after removal runs $4,500-$7,500 depending on open-cell versus closed-cell and whether we’re treating roof deck or floor only.
Several factors move the price:
- Attic accessibility. A scuttle hole in a closet costs more in labor than a full pull-down stair with headroom.
- Contamination level. Rodent-damaged insulation requires more PPE, more bagging, and sometimes sanitizing or rodent-proofing add-ons.
- Material type selected. Blown-in fiberglass from Johns Manville or Knauf costs less per square foot than Rockwool or CertainTeed spray foam systems.
- Air sealing extent. Homes with recessed can lights, whole-house fans, or complex HVAC duct routing need more sealing labor before insulation can perform.
To avoid overpaying, get a written scope that specifies removal depth, disposal method, air sealing details, and insulation R-value and type - not just a price per square foot.
