If you are planning to top up your attic or fill those hard-to-reach cavities, you are probably asking one critical question: how much for blown in insulation? At CountBricks, we answer that question every day for New York homeowners through our AI voice estimating platform. This article breaks down real-world cost ranges, the variables that influence pricing, and how CountBricks turns a confusing line item into a crystal-clear budget.
In most single-family homes, CountBricks data shows blown-in cellulose or fiberglass insulation landing between $1.65 and $2.90 per square foot of attic floor area. A 1,200 sq ft attic typically falls between $1,980 and $3,480 installed. These figures include material, labor, setup, disposal, and light air sealing—captured automatically by our AI when you walk an attic with your phone.
• Depth of existing insulation: heavier top-ups cost less per foot than bare-stud spaces
• Material choice: cellulose generally runs 5-8 % less than fiberglass in the Northeast
• Accessibility: walk-up attics cost less than tight hatch openings
• Prep work: baffle installation, vent chutes, and air sealing can add 10-20 %
• Regional labor rates: urban cores trend 8-12 % higher than suburban markets
The phrase “$2 per square foot” rarely tells the whole story. CountBricks AI listens to your field notes in real time and tags items a human estimator might miss:
1. Recessed lights needing IC-rated covers
2. Knob-and-tube wiring that requires specialist handling
3. Low-slope roof sections demanding netting to hold material
4. Weather delays in historic brownstones without interior loading zones
By capturing nuance, your final blown-in insulation number stays grounded in reality—not wishful averages.
• Cellulose: 80-85 % recycled paper, treated for fire and pests, R-value ~3.7 per inch, holds a slight cost advantage in dense-pack walls
• Fiberglass: spun glass fibers, inert, R-value ~2.8-3.2 per inch, popular for open-blow attics, marginally lighter per cubic foot
CountBricks catalogs live distributor pricing every morning, pushing updated per-bag costs into your estimate so you never quote yesterday’s rate.
