What should a contractor do when a customer asks for extras after the quote is signed?

Why extras feel small and cost big

The request almost always arrives casually. "While you are here, could you also..." The work sounds like twenty minutes, so you nod. Then it needs a part you do not carry, a second trip, and an hour of labor, and none of it is on paper. At the end of the job, the customer remembers agreeing to something small, and you remember doing something significant. That gap is where disputes start.

The problem is not the customer. Most people genuinely do not know what an extra involves, and they trust you to tell them. The problem is that a verbal yes has no scope, no price, and no record. Treat every extra as a mini quote, even when the number is modest, and the awkward conversation at the end never happens. Related: Itemized Quotes and Why They Build Trust

Pause, price, and put it in writing before you touch it

The habit is three steps. Stop and look at the extra the way you looked at the original job: what materials, how much labor, and whether it changes the schedule. Give the customer a price and a short description on the spot. Get approval, ideally a signature or a text reply that says yes, before you start. With a phone-based quoting tool this takes a couple of minutes because you can add a line item, attach a photo of the area, and send it for approval from the driveway.

Wording matters. Describe what is included, what is not, and whether the extra shifts the completion date. "Replace corroded shutoff valve under kitchen sink, part and labor, adds one hour, no change to completion day" is enough. If the extra depends on something you cannot see yet, say so and quote it as an allowance or a range with a not-to-exceed figure the customer agrees to.

What to do when the extra is really a discovery

Not every extra is the customer's idea. Sometimes you open a wall and find rot, or pull a fixture and find the wrong pipe size. This is a discovered condition, and it deserves the same treatment as a requested extra with one difference: photograph it before you disturb it further. A picture of the rotted subfloor with your boot for scale settles the question of whether the work was necessary.

Present the discovery calmly and with options where they exist. Repair now while the area is open, or close it up and schedule separately. Let the customer choose, and record the choice. Customers rarely object to paying for real problems. They object to feeling ambushed, and a photo plus a clear price prevents that feeling.

Small extras, goodwill, and where to draw the line

There is room for judgment. Tightening a loose handle or caulking a gap you noticed is goodwill, and it costs you little. The line is roughly this: if it needs a part you have to buy, more than a few minutes of labor, or carries any risk of a callback, it is a change order. Being clear about the line is not stingy. It is what lets you be generous with the truly small things without resentment. Related: Following Up on a Quote Without Being Pushy

Over time, tracking extras also teaches you something about your original quotes. If the same "extra" shows up on every water heater job, it belongs in the base quote or as a standard optional line. Your change order log becomes a source of better price book items and fewer surprises for the next customer. Related: Why the Fastest Quote Often Wins the Job
