Want the real quote, done for you?
This is a rough number. Vorkeon builds the full insulation quote from one sentence:
- Materials with waste, and crew time from your own pace
- Current prices from building-supply stores near the job
- A clean PDF with your logo that the customer signs on their phone
- Then the invoice, reminders and your crew's hours, in one app
What drives the price of an insulation job
- Insulation type. Batts, blown-in loose fill and spray foam differ a lot in cost.
- Target R-value. Higher R-values mean thicker layers and more material.
- Location. Open attics are easier than tight crawl spaces or finished walls.
- Air sealing. Sealing gaps and top plates first adds labor but helps the result.
- Old insulation removal. Vacuuming out damaged insulation is a job of its own.
- Baffles and vents. Keeping soffit vents clear needs baffles in attics.
A worked example
Example only, with made-up numbers, not a price guide. A 1,000 sq ft attic with blown-in insulation at 1.20 material and 0.80 labor per sq ft: 1,000 × 2.00 = 2,000. Add 400 for air sealing and 150 for baffles, for 2,550. With 25% markup the quote is 3,187.50 before sales tax. Check local material prices and any energy rules where you work.

Insulation quoting questions
How do I quote insulation by R-value?
Check the product label for how thick it must be to reach the R-value you want, then work out the bags or rolls for your area. Put the final R-value and depth in the quote so the customer can check it.
Should air sealing be priced separately?
Many contractors list it on its own line. It takes time, it is easy to skip, and showing it helps the customer see why your quote may be higher than a quick blow-in.
How do I price an insulation job?
Multiply the area to insulate by your material and labor cost per square foot, then add your markup to cover overhead and profit. Add tax on top when you send the quote.
What markup should I use?
Use the markup that covers your overhead (vehicle, insurance, tools, office) and leaves the profit you want. Many contractors land between 15% and 35%, but your own costs decide it.
