Change Orders Without Losing the Customer

Twenty-two feet into a ninety-foot trench, the bucket stops going down. Shale at fourteen inches, and you priced thirty. The homeowner is at the kitchen window with a coffee, watching.

What happens next is not a pricing problem. You'll get to the pricing in about twenty minutes and it isn't hard. What happens next is a trust problem, and contractors lose more money to how they handle the first ten minutes than to the rock itself.

The homeowner's fear is simple and it is not unreasonable: that you're about to discover expensive surprises for the rest of the week. Everything you do from here either confirms that fear or kills it.

The first ten minutes decide how the rest of the job feels

Stop digging. Not because you're dramatising it, but because every foot you cut after you know the price has changed is a foot you're working for free or a foot you'll argue about later.

Then go get the homeowner before they come get you. This is the whole thing. The contractor who walks to the door and says "come look at this with me" is a partner. The contractor who gets found out at 4pm and mentions it on the way to the truck is a problem.

Bring them to the trench. Put a tape in the hole so they can see fourteen inches themselves. Let them tap the shale with the shovel handle. A homeowner who has personally hit the rock with a shovel does not need to be convinced the rock is there.

Don't quote a number in that first conversation. Say you need twenty minutes to work out what it costs to do it right, and that you'll have it on their phone before you leave the yard. Numbers off the cuff are either too high, which starts a fight, or too low, which you eat.

Write the exclusion before you ever need it

The easiest change order conversation in the world starts with the homeowner saying "right, you told me about this." That only happens if your estimate said something about it in plain language on the day you sold the job.

Four exclusions cover most of what comes out of the ground on drainage and hardscape work:

• Rock and buried debris. Price assumes soil conditions consistent with the test hole. Rock, ledge, old concrete or buried fill requiring breaking or haul-off is priced as an addition at a stated hourly or per-foot rate.
• Private underground utilities. Public locate is arranged. Irrigation, low-voltage lighting, invisible fence, gas runs to a grill or pool heater, and septic laterals are not covered by public locate and are the owner's to mark.
• Off-site water. Price addresses water originating on this property. Flow entering from adjacent lots or the street is a separate scope.
• Restoration limits. Exactly what you put back, and what "back to grade, seed and straw" does not mean.

Say the rate in the exclusion, not just the fact of the exclusion. "Rock excavation billed at our machine-and-crew rate plus breaker rental" is a clause. "Rock is extra" is an argument waiting to happen. If your estimate doesn't have somewhere natural to put these, the line-by-line drainage estimate template walks through where they sit so they read as standard terms and not as fine print.

Three things change the price, and one of them is on you

Sort the surprise into a category before you talk money, because the category decides who pays and you should know the answer before the homeowner asks.

That last row of the middle section matters more than it looks. If you miscounted the run, or forgot the sleeve under the driveway, or didn't notice the deck was in the way, that is a takeoff error and the homeowner should never hear about it as a change order. Charging for your own mistakes is the fastest way to turn a good customer into a reviewer.

The neighbour-runoff case is the one contractors handle worst. It is genuinely new scope, and it is also genuinely something you could sometimes have caught. If the yard was dry the day you walked it, say so plainly: "I couldn't see this in July. I can see it now, and here's what it costs to deal with it."

Price the change with the same math you used on the estimate

Take the shale. You priced ninety feet at a trenching production rate you know from your own jobs — say the mini-ex and a three-man crew clear 40 feet an hour at 30 inches in your usual clay. Twenty-two feet are in. Sixty-eight to go.

In the first hour on rock you got eight feet. So:

• Normal: 68 ÷ 40 = 1.7 hours
• Rock: 68 ÷ 8 = 8.5 hours
• Extra crew time: 8.5 − 1.7 = 6.8 hours, call it 7

Now put your own loaded crew rate against it. If a man costs you $45 an hour fully loaded in your market, three men is $135 an hour, and 7 × $135 = $945. Add the breaker: rental plus delivery runs a few hundred a day in most markets — use your actual last invoice, say $425. Rock spoil doesn't go back in the trench the way soil does, so add a haul-off load at your dump rate, say $350.

Direct cost: 945 + 425 + 350 = $1,720.

Then apply the same gross margin you used on the base job, not a higher one. If you priced the job at 35% gross margin, divide rather than multiply: 1,720 ÷ 0.65 = $2,646. Round to $2,650 and that's the change order.

Two things about that arithmetic. First, every number in it is yours — production rate, loaded rate, rental, dump fee — and the whole point is that you substitute your own and the structure holds. If you don't know your real production rate in your real soil, that's a bigger problem than this change order, and tracking four numbers by hand across your next three jobs will tell you more than any benchmark will.

Second, do not raise your margin because the homeowner has a trench across the lawn and nowhere else to go. They will find out what a breaker rents for. Holding your normal margin is defensible in a way that opportunism never is.

What to say standing in the yard

Three moments, three scripts. Say them close to word for word until they're yours.

The stop. You've just hit it and you're walking to the door:

"I've stopped the crew. I want you to see what we're into before we go any further, because it changes the price and I'm not going to spend your money without asking. Have you got two minutes?"

The number. Twenty minutes later, back at the trench with the figure worked out:

"Here's where I am. Sixty-eight feet left, and in soil that's about an hour and three quarters. Through this it's eight and a half — I timed the first hour. That's seven extra hours of crew, a breaker rental, and a load of rock out of here, because it won't compact back in. It comes to $2,650, same margin I quoted the rest of the job at. The original number doesn't change. This sits on top of it."

The reassurance. This is the part most contractors skip, and it is the part that keeps the customer:

"I don't expect anything else. The rest of the run is the same soil you saw in the test hole, the outfall's already open, and the restoration is priced. If something does come up, you'll hear it from me the same way — I stop, you look, you decide."

Never say "it's going to be a bit more." Never say "we'll sort it out at the end." Never say "don't worry about it for now." Every one of those is a promise to have a worse conversation later, with less goodwill in the bank.

Sign it before the bucket moves again

Verbal change orders are how contractors end up eating rock. Not because homeowners are liars — most aren't — but because in six weeks the memory of a conversation in a noisy yard is thin, and the only thing still solid is the number on the original estimate.

Document it while you're standing there:

1. A photo of the condition with a tape or a shovel in frame for scale, and a wide shot that includes the house so there's no question which yard it is.
2. Ten seconds of video if it's water. Flow is unarguable on video and completely arguable in a sentence.
3. The station: "rock begins 22 feet from the north corner of the patio." Write it on the plan.
4. A written change with three lines — what was found, what you'll do, what it adds — and the revised total underneath.
5. A signature before work restarts. Not initials on a crumpled page that lives in the truck.

This is the part ScapesHQ was actually built for: you send the change as a second estimate on the same project, the homeowner signs it on their phone with the signature evidence recorded, and the whole sequence — original proposal, change, signature, timestamps — sits on one permanent timeline you can pull up months later. What it will not do is invoice the change or track your actual rock hours against the budget. Invoicing, payments and job costing aren't built, and you should keep doing those wherever you do them today.

When the answer is no

Sometimes the homeowner can't or won't pay it, and that's a legitimate answer. Have the alternatives ready before you ask, because "no" followed by silence turns into a stopped job and a stopped job turns into a dispute.

Usually there are three:

• Shorten the run. End the trench at the rock, put in a clean termination, and accept that the last twenty feet of the yard stays wet. Cheaper, honest, and it works for a lot of lots.
• Reroute. Go around the ledge if there's fall to do it. Costs some length, saves the breaker. Check your fall before you offer this, not after.
• Stop and settle. Bill the completed portion, restore what's open, and leave the door open. Rare, but better than pushing someone into a payment they resent.

If they don't say no to the work but do say no to the price, you're in a different conversation — that's a price objection, and the same tools apply as when a competitor's number comes up mid-job. Explain what the money buys, don't discount to end the discomfort, and be willing to offer less work rather than the same work for less.

One thing not to do: keep digging while you wait for a decision. Your leverage and your credibility both come from having stopped.

FAQ

Do I need a signed change order before I keep digging?

Yes, in practice. A verbal agreement in a loud yard is worth very little six weeks later when the final invoice lands. Get three lines in writing — what was found, what you'll do, what it adds — plus a signature and a timestamp before the machine moves again. It takes five minutes and it settles every argument that would otherwise happen at collection time.

How much should I mark up a change order?

The same gross margin you used on the base job, no more. Work out the direct cost of the change — extra hours at your loaded crew rate, rental, disposal — then divide by one minus your margin. Raising your margin because the customer has a trench across the lawn and no alternatives is the single fastest way to turn a good job into a bad review.

What if I cut an unmarked irrigation line?

Stop, photograph the cut with the locate marks or the absence of them in the same frame, and tell the homeowner immediately. Public locate services do not mark private irrigation, low-voltage lighting, invisible fence or gas runs to a grill, which is why your estimate should say so up front. If you named private utilities as an exclusion and the owner didn't mark them, the repair is a change order. If you cut it inside marked public utilities, that's an insurance call, not a change order.

Can I charge for the time my crew stands around waiting for a decision?

You can, but think hard about whether you want to. Billing for downtime on a surprise you discovered reads as punitive to most homeowners. The better move is to keep the decision window short — have the number ready in twenty minutes — and put the crew on another part of the scope, load-out or restoration prep, while they think.

Should I put a rock clause in every drainage estimate?

In markets with shallow ledge or heavy fill, yes, on every one. State the rate, not just the fact: rock excavation billed at your machine-and-crew hourly plus breaker rental and disposal. A clause with a number in it stops a conversation. A clause that just says 'rock is extra' starts one.

The short version

Stop digging the moment the price changes, walk the homeowner to the trench so they can see and touch the problem themselves, and tell them you'll have a number in twenty minutes. Price the change from your own production rates and loaded crew cost, apply the same margin as the base job, and get it signed before the bucket moves again. The exclusions you write on the original estimate — rock, private utilities, off-site water, restoration limits — are what turn this from a fight into a formality.
