INSULATION JOBS LOOK PROFITABLE. THE CASH IS STILL IN TRANSIT.
Insulation subcontractors run out of cash for reasons specific to how the work is built and billed, on jobs that are making money. The three that cost the most in this trade are below, taken from insulation contractor research. Most sit at 75 to 90 days from finishing work to holding the money, and 45 days is achievable.
Cash and profit are measured on different clocks. Your profit and loss records revenue when you invoice and costs when you incur them, while the bank account only knows what cleared. Labour goes out weekly and collects 45 to 90 days later, minus retention. That distance is what a growing, profitable insulation company funds out of pocket, and it widens as you grow. The specific things that widen it in this trade are what the rest of this page is about.
WHERE IT LEAKS OUT.
Insulation inspects before drywall covers it, which wedges the trade into the same middle-squeeze drywall lives in: mobilize after MEP rough-in inspections clear, finish before board hangs, and eat the compression when upstream slips. A failed insulation inspection (gaps, compression, missing air sealing) stalls the drywall trade behind it, which converts quality escapes into schedule liability.
WHAT MOVES MARGIN IN THIS TRADE.
The Blended Product Book
Batt, blown, and spray are three businesses with three cost structures sold under one estimate history. Whichever line is mispriced highest wins the worst work.
The Set-Yield Spread
Spray foam is bought in chemical sets and sold in board feet, and geometry, temperature, and overspray tax every set. The per-job yield reconciliation is the trade's truth report; skip it and the waste factor becomes folklore.
The Cover-Up Clock
Insulation passes inspection or the drywall behind it stalls; it mobilizes after rough-in or eats the compression. The trade lives in the schedule's narrowest slot and gets paid like it has float. (cfos-cash-flow-cycle-system) ---
DAYS SALES OUTSTANDING.
Ninety days is weak, 45 is the target, 30 is strong. Nothing else moves cash faster.
| Position | Days | What it means |
|---|---|---|
| Weak | 90 days | Roughly three months of work funded out of your own pocket. |
| Target | 45 days | Achievable on the days you control: submission timing, complete documentation, follow up in week two. |
| Strong | 30 days | Requires discipline every month, and it's the cheapest capital available to you. |
Moving from 90 days to 45 frees roughly annual revenue divided by 365, times 45 days. At $4M that's about $493,000. At $8M it's about $986,000. That money doesn't come from a bank and it costs no interest, which is why we work the cycle before discussing financing anything.
INSULATION BENCHMARKS.
Insulation subcontractors at $1M to $5M net 8 percent, against a CFOS target of 10 percent, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. Working capital should sit at 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.
