How to Handle a Change Order Before the Extra Work Starts

A practical change order template with scope, materials, schedule impact, and customer sign-off.

During an active project, unexpected conditions inevitably surface: hidden pipe corrosion behind drywall, rotted subflooring beneath old tile, or a homeowner asking, “While you’re here, can we also replace that lighting fixture?” Handling these moments professionally requires a transparent change order workflow before any extra labor or materials are committed.

Why informal verbal approvals lead to billing friction#

Contractors often hesitate to introduce written documentation mid-project out of fear of slowing down work or seeming overly bureaucratic. However, when extra work is agreed to verbally in passing, both parties easily misunderstand the financial or schedule impact. By the time the final invoice arrives with an unapproved $750 line item, the homeowner feels surprised, and the contractor faces delayed payment or unrecoverable labor costs.

A worked example: Bathroom subfloor structural repair#

To see how a professional change order protects both the project budget and the customer relationship, consider a real-world scenario from a residential bathroom renovation:

  • Original Contract: Guest bathroom tile and vanity installation ($4,200 contract, scheduled for 3 days).
  • Discovered Condition: Upon removing existing tile and mortar bed, the crew uncovers 32 square feet of water-damaged, rotted 3/4" subflooring and decayed joist edges around the toilet flange.
  • Materials Required: 2 sheets 3/4" CDX tongue-and-groove underlayment ($90), framing lumber and structural fasteners ($60), new PVC closet flange and hardware ($35) = $185 direct material cost.
  • Labor Allocation: 5 technician crew-hours for demolition, sistering two 2x8 joists, and installing subflooring. At a $65/hour burdened labor rate = $325 direct labor cost.
  • Direct Cost & Pricing: Total direct cost is $510 ($185 + $325). Priced at $780, generating a 34.6% gross margin ($270 gross profit) consistent with the base contract.
  • Schedule Impact: Adds 1 business day to completion. Tile setting shifts from Thursday afternoon to Friday morning.

Sample Digital Change Order Copy

“Change Order #1 — Guest Bathroom Renovation. Description: Remove rotted subfloor around toilet flange; sister two damaged 2x8 floor joists; install 32 sq ft 3/4” CDX subfloor; reset toilet flange. Materials & Labor: $780.00. Schedule adjustment: +1 business day (revised completion: Friday, Oct 16). Approval requested before beginning structural repairs.”

The decline protocol: What happens when a customer says no#

A change order is an offer, not an ultimatum. If a customer declines the additional work, follow a structured decline protocol to safeguard both parties:

  • Document the Decline in Writing: Record the customer’s decision directly in the project file, noting the date, time, and specific items discussed.
  • State Warranty Boundaries Clearly: If declining the change order affects other components, explain the consequences objectively (e.g., “Installing finished porcelain tile over compromised subflooring voids the tile installation warranty against cracking”).
  • Adjust Original Scope if Necessary: If the discovered condition creates a structural or code hazard that legally prevents continuing original work, pause the affected phase until a safe resolution is agreed upon.
