Why Demolition Contractors Run Out of Cash

QUICK ANSWER

Demolition contractors run out of cash because mobilization costs leave the account before the first pay application pays out, hazmat discoveries stall billing while the work keeps moving, and tipping fees swing job costs with no matching change order. CONTROL fixes it with demolition-specific cost codes, written billing standards, and a rolling cash forecast.

THE CASH PROBLEMS

The specific ways demolition contractors lose cash, pulled straight from what makes this trade different.

Mobilization Cash Flow

Trucks, machines, and crews cost real money before the first pay application cycle pays anything back. That spend comes out of your account weeks ahead of the check.

Hazmat Discovery Billing

An unexpected hazmat find stops billing on that scope while abatement drags on. Without a written change order standard, you absorb the delay for free.

Tipping Fee Variance

A tipping fee is the per-ton charge a landfill or transfer station collects to accept debris, and it moves with load counts and disposal rates after your bid is locked. You need cost codes that catch the swing while the job is still open.

Salvage Value Recognition

Salvage credits only count when you track them job by job. Most demo contractors let that money disappear into one general ledger line.

QUESTIONS DEMOLITION CONTRACTORS ASK
Why do demolition contractors run out of cash?
Demolition contractors run out of cash because heavy mobilization spend leaves the account before the first pay application pays out, and disposal costs keep moving after the bid is locked. Hazmat discoveries stall billing on live scopes at the same time. When those three collide in one month, a profitable contractor still misses payroll.
How do I bill for hazmat discoveries on a demo job?
You bill for hazmat with a written change order standard: the moment a suspect condition is documented, a notice and a priced change order go to the GC before abatement starts. Chapter 6 of CONTROL gives demolition contractors the billing dates, notice rules, and change order process that make this automatic instead of optional.
What profit margin should a demolition contractor target?
A demolition contractor should target 22 to 30% gross profit per project and 12% net profit after all expenses, with overhead between 9 and 13%. If your net sits under 5%, your tipping fees, mobilization spend, and salvage credits are almost certainly missing from your job costs.
