INSULATION JOBS LOOK PROFITABLE. THE CASH IS STILL IN TRANSIT.
Insulation subcontractors have no cash left 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 are 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 gets inspected before drywall covers it. That puts the trade in the same middle position as drywall. You mobilize after MEP rough-in inspections clear, finish before board goes up, and take the compression when upstream falls behind. A failed insulation inspection (gaps, compression, missing air sealing) stops the drywall trade behind it. So a quality miss becomes a schedule liability.
WHAT MOVES MARGIN IN THIS TRADE.
The Blended Product Book
Batt, blown and spray are three businesses with three cost structures, sold off one estimate history. The most mispriced line wins the worst work.
The Set-Yield Spread
You buy spray foam in chemical sets and sell it in board feet. Geometry, temperature and overspray cost you yield on every set. Reconcile yield on every job. Skip it and your waste factor is a guess.
The Cover-Up Clock
Insulation passes inspection or the drywall behind it stops. You mobilize after rough-in and take the compression. You work in the tightest slot on the schedule and get paid like you have float.
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 | You can get here on the days you control. Bill on time, send complete paperwork, and follow up in week two. |
| Strong | 30 days | Takes work every month. It's the cheapest money you can get. |
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 costs no interest and needs no bank. So we fix billing and collections before we talk about financing.
INSULATION BENCHMARKS.
Insulation subcontractors at $1M to $5M net 8 percent, against the CFOS net profit target, set at your trade's net profit average at your revenue plus 3.5 points, never below 10 percent, before taxes. The working capital target is 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.
