To bid a demolition job, price five cost groups and then add overhead and margin: labor and crew hours, equipment and rental, disposal by the ton, permits and utility disconnects, and any hazardous-material abatement. Disposal is usually the largest and most misjudged number, because landfill tipping fees are charged by weight and a structure produces more tons than people expect. Below is the step-by-step method, the line items most bids miss, and the walkthrough that keeps a profitable demo from turning into a loss.
We run home-service companies ourselves and watch margin get made or lost in the estimate. This is a practical bidding guide, not a sales pitch — the marketing part is only where we help, and we will say plainly where we do not.
Estimate the crew size and days, then multiply by your fully loaded hourly cost including payroll burden. Interior selective demo is hand work and slow; full structural is faster with the right machine but needs more cleanup.
Excavator or skid steer time, attachments, dumpsters, and any specialty gear. If you rent, price the rental plus delivery and fuel; if you own, charge an internal rate so the machine pays for itself.
The big one. Estimate debris weight, then price hauling and landfill tipping fees per ton at your local rate. Separating recyclable concrete and metal can lower the dump bill, so factor that in.
Most structural demolition needs a permit, and gas, electric, water, and sewer must be safely disconnected first. These add cost and lead time and are routinely underestimated. List them explicitly.
Older buildings can contain asbestos or lead that must be surveyed and abated by a licensed contractor before demo. Price a survey up front; finding it mid-job wrecks the schedule and the budget.
Sum the five groups to get your direct cost, then add overhead — insurance, office, your truck and tools — as a percentage, and finally your profit margin. Demolition carries real risk and liability, so do not bid it on a thin margin to win the job. A bid that does not cover the surprise tons or the disconnect delay is worse than no bid.
Last, sanity-check the total against the structure size and against past jobs of similar scope. If your number is wildly off from what comparable demos cost, find out why before you send it.
If your demolition work comes from GCs and developers who already know you, your pipeline is relationships, not search. Spend your energy nurturing those accounts and bidding cleanly. You do not need an agency to win repeat commercial work that comes by phone and reputation.
Where we help is the other channel: the homeowners and small businesses who search for a demolition contractor and pick whoever they find and trust first. If you want that work too, getting found and capturing those leads is what we do.
We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →

More for contractors: SEO for contractors, excavation website design, and the AI receptionist.
Price labor, equipment, disposal by the ton, permits and disconnects, and any abatement, then add overhead and margin and check the total against the structure size. Always walk the site first.
Disposal. Landfill tipping fees are charged by the ton and a structure makes many tons of debris, so misjudging weight or the dump rate is the fastest way to lose money.
Yes. Most structural demolition needs a permit, and utilities must be safely disconnected first. They add cost and time and are often underestimated, so list them as explicit line items.
Yes. Older buildings often contain asbestos or lead that must be surveyed and abated by a licensed contractor before demo. Price a survey up front so it does not blow up your timeline mid-job.
