FRACTIONAL CFO FOR WATERPROOFING CONTRACTORS.

QUICK ANSWER

We run the finance function for waterproofing subcontractors doing $1M to $12M: job costing aligned to the way you estimate, a 13 week cash flow forecast, monthly WIP, and a CFO in the room every month. Pricing starts at $1,900 per month.

Waterproofing sells a decade of silence, so the finance function is built around a liability that surfaces years after final payment. The industry spends about $8 billion a year fixing failed waterproofing and below-grade remediation exceeds $150 a square foot, which is why this trade's 26 to 29 percent gross margin is an insurance premium rather than a fat rate. We accrue warranty per job instead of hoping, because a warranty commits future crew hours against revenue recognized years earlier and a company without the accrual re-earns its old jobs every spring. Then we make documentation a deliverable: stage photos, written substrate acceptance, witnessed flood and spray tests, and burial turnover records, since buried work gets judged a decade later by whatever paper exists.

WHERE WATERPROOFING LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Uncharged Premium

The industry spends $8 billion a year fixing failed waterproofing, and below-grade remediation exceeds $150 per square foot. The trade's 26-to-29 percent gross margin is the insurance premium for that tail; discounting it's underwriting catastrophe risk for free.

LEAK 02

The Ten-Year Photograph

Buried work gets judged a decade later by whatever paper exists. Photo-documented installation, written substrate acceptance, and witnessed water tests are the only testimony the membrane will ever give.

LEAK 03

The Unreserved Callback

Warranties commit future crew-hours against revenue recognized years earlier. A per-job warranty accrual is what separates a 7.5-plus percent net from a company that re-earns its old jobs every spring. (cfos-job-profitability-system) ---

HOW SPM FIXES IT

WHAT WE CHANGE.

The $8 billion tail (why the margins are high)
Buried work, exhumed blame (the litigation pattern)
The warranty that outlives the balance sheet
Water testing as the payment gate
Sequence dependency (everyone builds on top of the membrane)

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Waterproofing contractors at $1M to $5M net 7.5 percent on average, the strongest floor among the served trades, rising to 10.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 11 percent. The margins are a risk premium: the trade absorbs a liability tail the rest of the industry spends $8 billion a year cleaning up. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
