Backcharge

In Plain English

Charging another contractor for costs you incurred because of something they failed to do or did incorrectly.

Definition

A backcharge is a cost charged by one contractor to another for correcting defective work, completing work that was the other party's responsibility, or cleaning up after another contractor. General contractors backcharge subcontractors, and owners backcharge general contractors. Backcharges must be documented with proper notice and supporting cost records.

Why It Matters in Bidding

Backcharge exposure should shape how a sub prices and qualifies its bid, because vague cleanup, safety, and coordination language lets the party above deduct costs from your payment after the fact. Documenting scope boundaries clearly in the proposal and insisting on notice rights is the cheapest insurance against absorbing someone else's correction costs out of your already-thin margin.

Example

The framing sub added a bid qualification limiting its cleanup obligation to its own debris, heading off a later backcharge after another trade left material stacked in the framer's work area.

Frequently Asked Questions

A change order adjusts the contract price or scope by mutual agreement, usually adding work and money. A backcharge is a one-sided deduction recovering costs one party incurred fixing or completing another's responsibility. Change orders increase what you are owed; backcharges reduce it, and unlike change orders they often arrive without negotiation.
It is legitimate when the cost was genuinely the other party's responsibility, notice was given, a chance to cure was offered, and costs are documented at actual value. It becomes abusive when used to recover the deductor's own inefficiencies, inflate costs, or deduct without notice. Contract notice provisions are the dividing line in most disputes.
Clearly define scope in the bid and subcontract, perform daily cleanup, fix deficiencies promptly when notified, attend coordination meetings, and document site conditions. Keeping your own area clear of other trades' debris with photos prevents you from being blamed for it. Most backcharges trace back to ambiguous responsibility, so precision up front is the best defense.
