We’ve been part of the Threshold Group family since 2002, and every Aspen Attic Insulation location operates to the same standard: background-checked, identity-verified technicians in clean marked uniforms who show a photo ID badge at your door. You get a written price before any work starts, and every job carries our 365-Day Done Right Promise. If something fails, we come back free. No voicemail loops either. A live person answers the phone 24/7.
We install and service three core systems: traditional attic insulation, spray foam insulation, and blown-in insulation. Our crews stock materials from eight leading manufacturers including Knauf, Rockwool, and CertainTeed, so we match the product to your specific attic conditions rather than forcing what’s on the truck.
Insulation Contractors
Insulation Contractors are specialists who evaluate, install, and maintain the thermal barrier between your living space and the outdoors. You need one when your energy bills climb without explanation, upstairs rooms stay cold in winter or hot in summer, or your existing insulation has compressed, gotten wet, or been disturbed by pests. Aspen Attic Insulation sends a technician who measures your attic, identifies air leaks and ventilation gaps, and gives you a written price before any work begins, following our Attic Insulation Maintenance Checklist for Los Angeles Homeowners. Typical attic insulation installation runs $1,500 – $5,500, while targeted repairs or top-offs usually fall between $400 – $1,200.
What We Inspect First
Our technician checks insulation depth, R-value, moisture staining, and attic ventilation balance using a thermal imaging camera. We photograph everything and review it with you on-site so you see what we see.
How We Protect Your Home
We seal the work area with plastic sheeting, use HEPA-filtered equipment when removing old material, and clean up thoroughly before we leave. Your technician’s name and photo arrive by text or email before the visit.
Attic Ventilation
Attic Ventilation is the controlled flow of outside air through your attic space to remove heat and moisture that would otherwise damage insulation, warp roof decking, and breed mold. You need it assessed when you notice rusted nail heads in your attic, frost on the underside of your roof in winter, or shingles curling prematurely from underneath. Aspen Attic Insulation installs ridge vents, soffit vents, gable vents, and powered attic fans as part of a balanced system designed for your specific roof geometry. Attic ventilation improvements typically cost $300 – $1,500 depending on the number and type of vents needed.
Signs of Poor Airflow
Ice dams along your eaves in winter, a superheated attic in summer, and musty odors wafting into living spaces all point to stagnant attic air. We measure intake and exhaust flow rates to diagnose exactly where the system falls short.
Ventilation and Insulation Together
New insulation without proper ventilation traps moisture and voids manufacturer warranties. We design both systems to work together, using baffles to keep soffit vents clear and calculating the 1:300 ratio most building codes require.
Radiant Barrier
Radiant Barrier is a reflective material, usually aluminum foil applied to oriented strand board or kraft paper, that blocks radiant heat transfer from a hot roof into your attic space. You need it most if your cooling costs spike in summer, your ductwork runs through the attic, or you live in a climate with intense sun exposure and high cooling loads. Aspen Attic Insulation installs radiant barrier as a standalone retrofit or integrated with new insulation, stapled to rafters or laid over existing insulation depending on your attic configuration. Radiant barrier installation typically runs $1,000 – $2,500 for an average home.
When Reflective Heat Dominates
Roof temperatures can reach 150°F or higher on sunny days, and that infrared radiation travels in a straight line to heat every surface below. Radiant barrier reflects up to 97% of this energy back toward the roof.
Product Selection
We source perforated radiant barriers that allow moisture passage and double-sided products for maximum reflectivity. Our crews know when to specify Icynene spray foam as a complementary air seal instead of or alongside reflective materials.
Attic Cleaning Services
Attic Cleaning Services remove debris, pest droppings, old storage items, and contaminated insulation to restore a safe, usable attic space. You need this before installing new insulation, after a rodent or bat infestation, or when preparing to sell your home and the inspection flagged attic conditions. Aspen Attic Insulation uses industrial vacuums with HEPA filtration, protective sheeting for your living areas, and proper disposal protocols for biohazardous material. Attic cleaning typically costs $500 – $2,000 depending on contamination level and attic square footage.
Health and Safety Protocols
Our technicians wear respirators and full protective suits when handling guano, rodent waste, or mold-affected materials. We seal HVAC ducts before starting and run negative air machines to prevent cross-contamination.
What We Find and Remove
Old fiberglass batts degraded by moisture, squirrel nests in soffits, decades of blown-in cellulose compacted below effective R-value, and homeowner storage that blocks ventilation paths. We document everything with photos for your records.

Attic Mold Removal
Attic Mold Removal is the controlled remediation of fungal growth caused by condensation, roof leaks, or inadequate ventilation that keeps attic surfaces damp. You need it when you see black, green, or white patches on roof decking or rafters, smell a persistent musty odor, or have a home inspector flag microbial growth before a sale. Aspen Attic Insulation treats affected areas with EPA-registered antimicrobial agents, removes unsalvageable materials, and fixes the moisture source so mold does not return. Attic mold remediation typically costs $1,500 – $4,000 depending on affected square footage and whether insulation replacement is needed.
Why Attics Grow Mold
Bathroom vents dumping moist air into the attic, missing or damaged insulation creating cold spots where condensation forms, and undetected nail pops or flashing failures letting rainwater saturate wood. We trace every moisture path to its origin.
Post-Remediation Verification
After treatment, we verify drying with moisture meters and can coordinate third-party air sampling if your lender or buyer requires documentation. Our 365-Day Done Right Promise covers our work if conditions recur due to our oversight.
Attic Insulation Removal
Attic Insulation Removal is the complete extraction of existing insulation material that has been compromised by water damage, pest infestation, fire, smoke, or simply age-related degradation below effective performance levels. You need it when insulation is compressed, moldy, urine-soaked, or contains asbestos-containing vermiculite that requires abatement protocol. Aspen Attic Insulation uses high-capacity vacuum trucks or bagged removal depending on material type, with full containment to protect your living space. Attic insulation removal typically costs $1,000 – $3,000, with asbestos-containing materials requiring specialized abatement at $4,000 – $10,000.
Material Identification
Our technicians can identify fiberglass batts, cellulose, mineral wool, vermiculite, and urea-formaldehyde foam by sight and texture. We test suspicious materials and follow EPA guidelines for safe handling and disposal.
Preparing for New Installation
After removal, we inspect and air-seal all penetrations, top plates, and chimney chases before any new insulation goes in. Skipping this step wastes money. We document the sealed attic with photos for your project file.
Brands We Service
We stock and install materials from eight industry-leading manufacturers so the right product goes into your attic, not just what was available at the distributor this morning. Our crews train directly with Knauf on their EcoBatt and Jet Stream products, and we regularly specify Knauf insulation for homeowners sensitive to traditional fiberglass binders. We’ve installed Rockwool stone wool insulation in hundreds of attics where fire resistance and sound dampening matter as much as thermal performance. CertainTeed’s Optima and InsulSafe lines are our go-to when we need consistent coverage depth with minimal settling over time. We also work extensively with Owens Corning, Johns Manville, Icynene, Demilec, and GreenFiber.
Whether you have a preference for a specific brand, your architect specified a particular product, or you want our recommendation based on your attic conditions and budget, we can help. Every material we install is covered by the manufacturer’s warranty plus our 365-Day Done Right Promise on workmanship.
Signs You Need a Pro Right Now
- Energy bills jump 20% or more without a rate increase. This usually means heated or cooled air is escaping faster than your system can replace it. Your insulation has likely settled, gotten wet, or was never adequate for your climate zone to begin with.
- Upstairs rooms are more than 5 degrees different from downstairs. Heat rises, and without adequate attic insulation it keeps going right through your ceiling. This temperature stratification wastes money and makes upper floors uncomfortable.
- You see water stains or frost on roof decking or rafters. Moisture in your attic destroys insulation R-value, breeds mold, and rots structural wood. The longer it continues, the more extensive and expensive the repair becomes.
- Your insulation is less than 10 inches deep or you can see ceiling joists. Current DOE recommendations call for R-38 to R-60 in most attics, which translates to 12 – 20 inches depending on material type. Shallow insulation is underperforming insulation.
- You’ve had rodents, bats, or squirrels in the attic. Pest waste contaminates insulation with pathogens and odors, and disturbed batts create gaps where heat flows freely. Cleaning and replacement protects your family’s health and your home’s efficiency.

How Much Does Attic Insulation Cost?
A typical complete our Attic Insulation in Los Angeles installation runs $1,500 – $5,500 depending on attic square footage, accessibility, material type, and whether old insulation removal is needed first. Blown-in cellulose or fiberglass for an average 1,500-square-foot attic usually falls at the lower end, around $1,500 – $2,500. Spray foam insulation, which air-seals simultaneously, ranges $3,000 – $5,500 for the same footprint. Targeted repairs or top-offs where existing insulation remains in place typically cost $400 – $1,200.
Several factors push prices higher or lower. Attics with limited access hatches, steep roof pitches, or extensive obstructions like HVAC ducts and recessed lighting take more labor. Removal of contaminated or wet existing insulation adds $1,000 – $3,000. Air sealing penetrations before insulating is essential for performance but adds time and material cost. Mold remediation, if needed, runs $1,500 – $4,000 before new insulation can be installed.
To avoid overpaying, get at least one written estimate that specifies material brand, R-value, and coverage area rather than a vague per-square-foot number. Be wary of quotes that seem to include everything but lack line-item detail. Our free estimates break out each component so you understand exactly what you’re buying.
Every Aspen Attic Insulation estimate includes the attic inspection, material, labor, cleanup, and our 365-Day Done Right Promise at no extra charge. There is no trip fee for the estimate, and you are never obligated to proceed.
