Insulation Estimating & Bidding Software
Insulation estimating is area and R-value work, with install method driving most of the labor difference. Batt, blown, and spray foam price and install very differently at identical coverage. Pro Spec IQ makes material type an explicit input so the labor follows the method rather than an average.
What Pro Spec IQ tracks on a insulation bid
Beyond material, labor, and equipment, insulation bids get inputs specific to the trade:

These are editable defaults, not fixed rates. Set them per bid to match your own cost structure and the risk on the job.
What drives cost on insulation work
- Square footage of wall, ceiling, and floor area to be covered
- Required R-value, which sets thickness and material quantity
- Material type — batt, blown, rigid, or spray foam
- Cavity depth and framing spacing
- Air sealing scope, which is often bid alongside but priced separately
Where these estimates go wrong
- Using one labor rate across batt and spray foam
- Missing air sealing scope that the energy code requires
- Not accounting for access difficulty in attics and crawlspaces
- Estimating from floor area rather than actual surface area to be covered
Insulation estimating questions
How do you estimate an insulation job?
Measure the actual surface area to be insulated, confirm the required R-value, and select material type. Price material from area and thickness, apply labor hours appropriate to the install method, add equipment, then apply markups. Pro Spec IQ tracks area, R-value, and material type as separate inputs.
Does install method really change the estimate that much?
Yes. Batt, blown, and spray foam differ in both material cost and the hours and equipment required, so a single blended per-square-foot rate tends to overprice some jobs and underprice others.
What markups does the insulation estimator start with?
Insulation bids default to 10% overhead, 18% profit, and 5% contingency, all editable.
