Try it as a customer would
Fictional business and sample prices. Preliminary estimate based on the answers; final pricing follows an assessment.
Questions included
- What does the insulation in your attic look like now? Fluffy or loose insulation, or none at all · Pebbly gray-brown or gold granules (vermiculite) · Soiled by mice, rats or raccoons, or wet and moldy “I don't know” → shows a price range
- How big is your attic floor? Measured in sqft “I don't know” → uses a stated assumption
- How much insulation is up there now? None, or almost none · A little: the tops of the joists still show · Some: the joists are covered “I don't know” → shows a price range
- Which blown-in insulation would you like? Blown cellulose · Blown fiberglass
- Should we air-seal the attic floor first? Yes · No
- Are there vent baffles at the edges of the attic? Yes, they're there · No, add them “I don't know” → shows a price range
- Should we insulate and seal the attic access? Yes, insulate and weatherstrip the hatch · Yes, an insulated cover for pull-down attic stairs · No, leave it
Prices you supply
- Blown-in insulation to your R-value, with depth rulers Your rate per sqft
- Extra depth for a thin or empty attic Your rate per sqft
- Old insulation vacuumed out and hauled away, attic sanitized Your rate per sqft
- Air sealing the attic floor Your rate per sqft
- Vent baffles along the eaves A fixed extra when it applies
- Attic access insulated and sealed A fixed extra when it applies
- Minimum job priceNo estimate shows less (sample: $1,000)
- Assessment rule: VermiculiteVermiculite can contain asbestos. It has to be tested, and removed by a licensed crew if needed, before we insulate. We'll plan that with you on a visit.
How the price is worked out
Each R-value has a rate per square foot of attic floor for each material. In the sample, 1,000 sq ft of blown cellulose is $1.20, $1.50 or $1.80 per sq ft ($1,200, $1,500 or $1,800). A thin layer already up there adds $0.35 per sq ft for the extra depth ($350), air sealing the attic floor is $0.75 per sq ft ($750), and insulating and weatherstripping the hatch is $200. That gives $2,500, $2,800 and $3,100 before tax.
An empty attic adds $0.70 per sq ft for the extra depth instead, and an attic whose joists are already covered adds nothing. Insulation soiled by animals or water is vacuumed out and hauled away at $1.75 per sq ft. Vent baffles along the eaves are $450, and an insulated cover for pull-down stairs is $375. Vermiculite goes to an assessment, because it can contain asbestos. If the customer doesn't know the attic size, they can work it out from their house's length and width, or the estimate assumes 1,000 sq ft and says so.
What you can change
- Rates per square foot by material and R-value.
- Extra depth, removal, air sealing, baffle and hatch prices.
- Package names, depths and warranty wording.
- Your minimum job price and rounding.
What still needs your visit
Ventilation, wiring and lights in the attic, and the real depth of what's there. The estimate shows its assumptions and says the price is preliminary.
