Job costing for insulation contractors

Insulation work is fast and repetitive, which makes small overruns easy to miss: a few extra sets of foam per house, or an extra hour per home, add up across a subdivision. JobMargin shows cost per home while the phase is still running.

What insulation contractors track in JobMargin

• Material by the set or bag. Foam sets, batts, and blown-in post to the job as you buy them, so yield problems show up early.
• Crew hours per house. Crews clock in on their phones at each lot, and hours post to the job automatically.
• Scope by house or area. Line items like “Attic, open-cell, Lot 14” become the job’s scope, and progress is logged as each is finished.
• Repeat builders. Win rates and job history by customer show which builders’ jobs actually pay.

Set up for insulation from the first day

When you pick Insulation as your trade, JobMargin loads these cost categories for budgets, receipts, and job costs. You can rename or add your own at any time.

Bid line items use the units insulation actually bid in: square feet (SF), linear feet (LF), each (EA), and lump sum (LS).

Example: what a insulation job looks like mid-way

Closed-cell foam at the rim joists, open-cell in the attics, and batts in the walls, on 14 homes. Nine homes are done.

Nine of 14 homes is 64% of the work. Material is close at 68%, but labor is 74% spent: about $1,980 of labor per home against a bid of about $1,710. At this pace, labor finishes about $3,700 over budget, small on one phase but real money across a builder’s whole year.
