Top 3 business mistakes we see demolition contractors make
Demolition has better margins than most site work and more ways to lose them. Three patterns account for most of what goes wrong.
Mistake 1: Bidding scrap as if it were guaranteed revenue
Scrap is real money and it belongs in the analysis. The mistake is letting it into the bid as a fixed credit.
Number one heavy melting steel has recently traded around $352 a ton, with yard quotes on mixed material in the range of eight to eleven cents a pound. Those numbers move. They move on export demand, on mill capacity, and on freight, and they can move meaningfully inside the months between when you bid a job and when you haul the steel.
A contractor who bids a structural job assuming 400 tons of recoverable steel at $350 has put $140,000 of unhedged commodity exposure into a fixed-price contract. If scrap drops 25% between bid and haul-off, $35,000 of margin disappears and there is nothing to do about it. If the tonnage estimate was optimistic — and tonnage estimates are frequently optimistic — it compounds.
What better operators do:
- Bid the job to stand on its own without scrap, and treat recovery as upside rather than as a line that closes the gap between your number and the low bidder's.
- If scrap has to be in the bid, discount it hard — both the price assumption and the tonnage estimate.
- Lock pricing where the volume justifies it. On larger jobs, forward arrangements with a processor convert a commodity bet into a known number.
- Track realized versus bid recovery on every job. Most contractors who have never done this discover their estimates run consistently high in one direction.
Mistake 2: Financing attachments on the carrier's term
This is the structural error that quietly eats equity.
A contractor buys a package — say a $340,000 carrier plus $180,000 in shears, a pulverizer, and a breaker — and finances $520,000 over sixty months because that is the payment that works. It is one machine on the invoice, so it becomes one note.
But the two halves of that package do not age together. The excavator is a ten-to-fifteen-year asset. The attachments run in abrasive material, consume wear parts continuously, and reach the end of economic life far sooner. Three years in, the shear may need a rebuild that costs a meaningful fraction of what you paid for it, and you still owe two years of payments on the original purchase.
The matched structure carries a higher payment in years one through three and a materially lower one after. More importantly, when the attachment is spent, it is paid for — which means you can replace it rather than running worn tooling because the balance sheet will not allow anything else.
Running worn tooling is its own cost. Slower cycle times, more downtime, more carrier wear. The financing structure quietly determines production.
Mistake 3: Treating insurance as a fixed cost
Demolition carries risk that most contractors do not price and most policies do not automatically cover.
General liability is the visible piece and it is manageable. The exposures that hurt are the ones outside it: pollution liability is generally a separate policy, not a rider, and asbestos, lead, and contaminated soil are exactly the conditions demolition contractors encounter. Abatement can add several dollars a square foot to a job's cost, and the liability tail extends long past the certificate of completion.
The mistake is not underinsuring on purpose. It is treating the premium as overhead that arrives annually and cannot be influenced, when in practice it is one of the more controllable large costs in the business:
- Know what your policy actually excludes before the job, not after the claim. Pollution, subsidence, and damage to the structure being demolished are common gaps.
- Price hazardous conditions as a separate line. Discovering asbestos mid-job on a fixed-price contract is the classic way a profitable demolition job becomes a loss.
- Bring your carrier the good news too. Documented safety programs, operator training, and a clean claims history are what move renewal pricing, and most contractors only talk to their broker when something has gone wrong.
- Match coverage limits to the work you are actually chasing. Higher-value commercial work commonly requires higher limits, and finding that out during a bid is expensive.
What the three have in common
Each is a case of treating a variable as a constant. Scrap price is not fixed. Attachment life is not the carrier's life. Insurance cost is not a fact of nature.
Demolition margins are good when the variables are managed and thin when they are assumed away. The companies that build equity in this business are usually not the ones with the newest fleet — they are the ones who bid conservatively on the commodity, structure their equipment debt to match what it is secured by, and treat risk transfer as an active line item.
The bottom line
If you fix one of the three this year, fix the financing structure. It is the only one entirely within your control, it takes one conversation, and it compounds every time you buy tooling.

Frequently asked questions
Should demolition contractors include scrap value in their bids?
Include it in the analysis, but be careful about relying on it to win work. Scrap prices move with export demand, mill capacity, and freight, and tonnage estimates frequently run optimistic. A safer approach is to price the job so it stands on its own, treat recovery as upside, and where scrap must be in the number, discount both the price assumption and the tonnage estimate or lock pricing forward with a processor.
Why should attachments be financed on a shorter term than the excavator?
Because they wear out much faster. An excavator is commonly a ten-to-fifteen-year asset while shears, pulverizers, and breakers run in abrasive conditions and reach the end of economic life far sooner. Financing both over the same long term leaves you owing money on tooling that is already spent, which often forces contractors to run worn attachments and lose production.
What insurance do demolition contractors commonly overlook?
Pollution liability is the most common gap, because it is generally a separate policy rather than part of general liability, and demolition work regularly encounters asbestos, lead, and contaminated soil. Damage to the structure being demolished and subsidence exposures are also frequently excluded. Reviewing exclusions before bidding rather than after a claim is the practical fix.
How much does demolition equipment cost?
It varies widely by class. High-reach demolition excavators commonly run several hundred thousand dollars into seven figures, standard carriers in the 36-ton class range from under $100,000 used to roughly $400,000 new, and attachments span from around $15,000 for a breaker to well over $250,000 for a large multiprocessor. Condition and rebuild history drive enormous variance, particularly on attachments.
What is the most common financial mistake in demolition?
Treating variables as constants. The three that come up most are bidding scrap revenue as though it were contracted, financing fast-wearing attachments on the same long term as the carrier, and treating insurance premiums as a fixed overhead item rather than a controllable cost tied to coverage design and claims history.
