WATERPROOFING JOBS LOOK PROFITABLE. THE CASH IS STILL IN TRANSIT.
Waterproofing 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 waterproofing 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 waterproofing 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.
On well-managed jobs, flood tests, ASTM-standard spray and dam tests on plazas and balconies, and integrity testing gate acceptance. On badly managed ones, nobody tests until the tenant's ceiling stains. Bill testing as its own line, witnessed and documented. Then acceptance is a record and no longer an opinion, the same as the flooring-moisture and FF/FL records.
WHAT MOVES MARGIN IN THIS TRADE.
The Uncharged Premium
The industry spends $8 billion a year fixing failed waterproofing. Below-grade remediation costs more than $150 per square foot. Your 26-to-29 percent gross margin is the insurance premium for that risk. Discount it and you're covering catastrophe risk for free.
The Ten-Year Photograph
Once your work is covered, it gets judged a decade later by whatever paper exists. Installation photos, written substrate acceptance and witnessed water tests are the only proof you'll have.
The Unreserved Callback
A warranty commits crew-hours years after you booked the revenue. A warranty accrual on every job is the difference between a 9 percent net before taxes and a company that re-earns its old jobs every spring.
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.
WATERPROOFING BENCHMARKS.
Waterproofing subcontractors at $1M to $5M net 9 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.
