Homeowners and builders alike ask the same question before opening a single bag of cellulose or fiberglass: how much for blown in insulation? While national averages help, every residence is unique. CountBricks combines real-time voice capture with live material pricing to give you a precise answer in minutes, not days.
• Loose-fill cellulose made from recycled paper
• Loose-fill fiberglass engineered from spun glass fibers
• Mineral wool products for enhanced fire resistance
All three products are installed with a blowing machine that packs the material into attic floors, wall cavities, and tight structural voids.
• Average per-square-foot material cost: $0.80 – $1.25
• Typical installed cost (labor + material): $1.50 – $3.00 per sq ft
• Whole-house attic (1,000 sq ft at R-38): $1,500 – $3,000
These figures come from aggregated CountBricks project data across thousands of residential builds. Your exact number depends on several variables outlined below.
1. Material Type: Cellulose generally runs 10 % less than fiberglass, while mineral wool commands a 15 % premium.
2. Required R-Value: Colder zones demand thicker coverage. Bumping an attic from R-30 to R-49 can add 30 % to material volume.
3. Square Footage & Accessibility: Open attics are faster to insulate than dense retrofit wall cavities, lowering labor hours.
4. Prep & Air-Sealing: Blocking vents, patching holes, and installing baffles often add $0.25 – $0.40 per sq ft.
5. Regional Labor Rates: Metropolitan areas trend 20 % higher due to wage scales and insurance costs.
6. Disposal of Old Insulation: Removing vermiculite, damaged fiberglass, or rodent-infested batting costs $1 – $2 per sq ft before new product is blown in.
Manual takeoffs force you to juggle bag coverage charts, local code tables, and supplier price sheets that change weekly. CountBricks automates the entire workflow:
• Snap a photo of your blueprints or speak dimensions aloud
• Our AI measures cavities and calculates volumes in real time
• Live supplier feeds push today’s bag prices directly into the estimate
• Labor hours are benchmarked against recent CountBricks projects in your ZIP code
The result is a line-item breakdown so transparent that homeowners can see exactly where every dollar goes.

Does blown-in insulation settle over time?
Yes, typically 10 % for cellulose and 3 % – 4 % for fiberglass. CountBricks calculators add extra depth to maintain the target R-value after settling.
Can I add new loose-fill over old batt insulation?
Absolutely. Our AI factors existing material R-value so you only pay for the extra inches needed.
Do I need vapor barriers?
Local codes vary. CountBricks references jurisdictional requirements and flags if additional vapor control layers are required.
