Change order template and hidden damage clause: rot behind the wall, charge more or eat it?
- Free. The hidden conditions clause and change order form comes by email as a PDF, a Word file and a Google Doc.
- Deepsel is our product: free estimate, invoice and scheduling software for contractors (scheduling, quotes, invoicing, card payments). One section, the one before the FAQ, says what it does and doesn't do for this job.
- Owner quotes come from Reddit threads I read or our team checked. Allowance and markup figures are what a handful of owners say they use, not a survey.
- Not legal advice. State rules come from the statutes and agency pages listed under Sources, read on November 4, 2026, and your state contract page has the rest.
Charge for it when it was truly hidden and your contract already says how. Eat it when the miss is yours. Truly hidden means neither of you could see it, count it or test for it before signing: rot under the tile, a notched joist behind the drywall. A miss is something you could have priced, or plain slow work. The answer is mostly settled before demo by three things in the contract: a hidden damage clause, an allowance (owners mention 10 to 15%, and one says 20 to 30% on small residential jobs), and prices for the usual finds. On the day, stop, make it safe, photograph it, show the client, and get a signed change order before you fix anything.
The template is a free hidden conditions clause and change order form. It has the clause to paste into your contract, a price list for common finds with blanks for your prices, a one-page change order (photo numbers, options, the old and new contract price, approve or decline, both signatures) and a photo log with the script below. It works for changes the customer asks for, too. Get it three ways: make your own copy in Google Docs, download the Word version (.docx), or download the PDF. Pick a format, enter your email and I'll send the links.
This is the money problem contractors argue about most. In our count of live Reddit threads from the past 12 months, hidden conditions drew more comments than any of the 18 business topics we tracked for contractors, remodelers and handymen: 8 threads, 1,200 comments.1 One title from December 2025 asks it outright: "The task just got bigger, do you charge more or eat it?"2 The pages that rank for "change order template" are blank forms and software vendors, and none of them starts from what you found behind the wall.
Charge more or eat it: who pays for what
One question sorts most cases. Could you have seen it, counted it or known it when you priced the job? A handyman who bid a fascia and painting job far too low asked r/handyman on day 5 whether he could revise his quote. The top answer: "If the error is a result of your estimation skills - you have to eat it." The same commenter drew the line I'd use: "If you discovered other conditions that weren’t clear or weren’t disclosed at time of quote, that can be discussed. Most guys have language for that in their contracts."3 Another told him how it sounds from the other side: "I severely undercut all other bids in order to secure the job with the intent to change order it to at or above the other bids mid job when the customer is held hostage and cannot back out with me." He ate it.3
| What happened | Who pays |
|---|---|
| It was behind a wall, floor or ceiling, and neither of you could see it (rot under the tile, a cut joist, a drain leaking inside the wall) | The customer, on a signed change order, at the prices in your contract |
| The customer changed something, or something they told you turned out wrong | The customer, on a change order. In the fascia thread, the homeowner's paint sprayer that didn't work was the part commenters said he could reprice |
| You could see it or count it and didn't price it: a soft floor by the toilet, a stained ceiling, a second layer of flooring at the doorway | You. The template's clause says so in writing (H.9) |
| Your hours or materials ran over: a slow day, a second coat, the wrong tool | You |
| You suspected it, said nothing in writing, then found it | Split it. One commenter's compromise: "charge for the extra parts needed, but not labor, if there is a complaint about the upcharge."2 Next time, name it before they sign |
| You or your crew caused it | You |
Timing turns a real hidden condition into your loss: fix it first and ask later, and you're arguing about a bill for work they never saw priced. A flooring installer in r/Construction found the subfloor around a washer drain "mush and rotted", told the homeowner it would cost "an additional $500 for the repairs", got a spoken OK, did it, and wasn't paid for it. The top reply: "Next time pause the work and do a change order- get it in writing."4 A handyman called to fix a shaky toilet found "the floor was rotted out", did four days of work and billed $1,100. The man paying called it a "$300 job". The question in the comments nobody could answer for him: "did you have any conversation about cost with the customer before you started? Or at least once you figured out it wasn’t simple fix?"5
Before demo: the hidden damage clause
Lawyers call it a concealed conditions or unforeseen conditions clause. The federal version in government building contracts covers "Subsurface or latent physical conditions at the site which differ materially from those indicated in this contract", and the contractor must give written notice "before the conditions are disturbed."6 A home job needs less law and more steps. Owners put the idea in one line: "Mine specifies any unknown conditions that arise trigger a change order if the scope of work changes."7 A handyman's template says it this way: "We will stop work if we come across something that will cost more and we run it by them after we thoroughly explain the problem and associated costs and will not proceed until they give the ok."8
The template's clause (Part 1) has ten short sections. These are the ones that settle the argument:
| Line | Wording you can copy (template Part 1) |
|---|---|
| What counts (H.1) | "A hidden condition is something behind a wall, floor or ceiling, under a fixture or finish, or inside the structure that neither of us could see, or reasonably expect from looking, before the work started." Then a list of examples, from rot to work not done to code. |
| What you looked at (H.2) | "Before pricing we checked [the floor around the toilet and tub, under the sink, the crawlspace]. We told you we might find [soft subfloor at the toilet flange]." The customer initials it. |
| Stop and show (H.3) | "We stop the work it affects and make it safe at no charge ... We do no extra work until you sign the change order." |
| Specialists (H.7) | Mold over about 10 square feet, material that may contain asbestos, lead paint in a pre-1978 home and structural damage are not in your price, and the clause says who handles each. |
| If they decline (H.8) | "The condition is left as found. We won't cover up a condition that is unsafe, is actively leaking, or would fail inspection." |
| What you could see (H.9) | "Damage or conditions we could see, measure or test before you signed are in the contract price." |
H.2 is the line most contracts skip. It turns your walk-through into a record of what you warned them about, and it keeps you honest: what you could see belongs in the price (H.9).
The allowance: how much contingency to set aside
The clause says how a find is priced. The allowance says where the money comes from. Owners' figures run from 10 to 30%: "Build a 10% contingency or additional work allowance in."9 One GC includes "a change order allowance in every contract that’s about 12% of the contract price."10 A remodeler's budget before design: "Estimate $125-150,000 plus 15% contingency for unforeseeable conditions."11 And on small jobs: "Having a contingency line item of 20% to 30% for small residentoal projects is a requirement for the client's budgeting process."12 That's four owners, not a survey. I'd go lower where you've seen the subfloor and the crawlspace, and higher on an old house with a known leak or a room you couldn't get under.
Then say which way it works (template H.5): inside the price, with the unused part credited on the final invoice, or outside it, as money the customer keeps ready. Inside is easier to collect. Outside makes your bid look lower and the surprise bigger later. Either way, get initials. Our construction estimate template has a line for a named allowance sized in units, like 20 square feet of subfloor at the tub, which is easier to explain than a bare percentage.
Prices for the usual finds
Rot is the find you'll price most, so give it a unit before you need one: per 4x8 sheet of subfloor or sheathing, per joist sistered, per foot of sill plate or rotten trim, per stud. Old wiring and old pipe go to your licensed electrician or plumber, at their price plus your markup. Mold beyond a small patch, asbestos and structural damage go to a specialist or an engineer, at their written price. The template's Part 2 has 17 lines with the prices blank, because I found no honest market price for any of them. Build yours from your own costs ("How to price it on the spot" below shows how), and add a return-trip charge.
Say it before they sign
The Journal of Light Construction ran a piece on change order conversations in August 2026, and its best line is the one to say at the table: "If something changes, we’ll pause, price it clearly, and get your approval before moving forward."13 Then go through the allowance and the price list and get initials on both. Something you can say: "This house is from 1962 and the toilet rocks, so the subfloor under it may be soft. If it is, it's $[260] a sheet, it's on this list, and I'll show you before I touch it. That's what the $[1,800] allowance is for, and whatever we don't use comes off your last payment."
On the day: stop, make it safe, photograph
- Stop the work it affects. Keep working elsewhere if you can.
- Make it safe, at no charge. Water off, power off, cover it. As one reply put it, "if it’s actively leaking, you have to stabilize the leak first."2
- Photograph it before you disturb it more. Wide, so the room is recognizable, then close with a screwdriver in the rot, a moisture reading or a tape across the damage. Number the bad pieces in paint so the count on the form matches. Part 4 of the template is the list.
- Tell them now, not at the end. "Telling them at the end of the job that there’s an adjustment doesn’t look good. Telling them as soon as you realize it is much better and understandable".2 A customer in the same thread: "I’ll happily pay more if there was a hidden issue discovered outside the scope of work. As long as the issue was brought up to me in a timely manner, don’t wait until project completion."2
- Write the change order before the work. If the customer isn't there, text the photos and the form.
What to say with the client watching
Bring them to it. Let them look, and let them push the screwdriver in if they want to. Then keep to five steps: acknowledge, explain, give options, give the numbers, and stop talking. They come from Greg Woleck's JLC piece, and they're the best structure I found.13 With the worked prices from the next section, it sounds like this:
- Acknowledge: "I know this isn't what you wanted to hear. Come and have a look."
- Explain: "When we pulled the tile, the subfloor around the toilet was soft. See how the screwdriver goes in? That's water from the toilet seal, probably for years. Neither of us could see it with the tile down."
- Options: "We can cut out this section and sister the one bad joist under it, or replace the subfloor across the whole room while it's open."
- Numbers: "The first is two sheets and one joist at the prices in your contract, $830, and it adds a day. The whole floor is $[ ] and two days."
- Pause: "Take a minute. What questions do you have?" Then wait.
What not to do. Don't apologize: Woleck's rule is "Your team should never apologize for a legitimate change order."13 Don't blame the last contractor or the homeowner; describe what you see. Don't guess a number you can't hold. If the find isn't on your price list, say when the written price will come and that nothing happens until they sign it. And don't start on a spoken yes.
How to price it on the spot
Four ways, best first:
- The contract price times the count. If it's in Part 2, count, multiply, write it down. This is why you set the prices before demo.
- A fixed price you work out at the truck. Your hours at your labor cost, the materials, any sub, then your markup. Owners add their usual markup: "when there are change orders (adding or subtracting) I charge 20%."14
- Time and materials with a cap, when you can't see the end of it. "This is a textbook change order. Bill time & materials," one reply in the eat-it thread said.2 Write a not-to-exceed amount on the change order, and stop and ask again when you reach it.
- A specialist's written price plus your markup (electrician, plumber, mold or asbestos company, engineer). Write "price to follow" and don't start until it's signed.
Here's the second way worked through for the toilet floor. Every input is made up to show the math, using the example settings from our construction estimate template: a $32 wage with 30% burden ($41.60 an hour), and 20% overhead plus 10% profit, which is a 1.32 markup.
| Find | Labor | Materials | Cost | Price (cost x 1.32, rounded) |
|---|---|---|---|---|
| Subfloor, per 4x8 sheet, cut out and replaced | 3 crew-hours x $41.60 = $124.80 | $70 | $194.80 | $257.14, call it $260 |
| Floor joist sistered, up to 12 ft | 4 crew-hours x $41.60 = $166.40 | $65 | $231.40 | $305.45, call it $310 |
| Two sheets and one joist | $830 |
Time yourself on the next one and use your supplier's prices. A 1.32 markup is a 24% gross margin, and our contractor markup guide has the arithmetic. A handyman pricing from a private hourly number does the same thing with that number, and a find that takes 20 minutes still costs at least your minimum (owners put theirs at a median of $150, on our handyman price list page).
Decide when you get paid for it, too. "Our contract with the client states that change order work must be approved and paid in full before the work begins."9 Another owner: "I charge 100% up front for most change orders".15 If the find comes out of an allowance, there's nothing to collect until the final invoice.
The change order form: what it must contain
A change order is a short signed form that changes the contract: what's added or taken out, the price and the time. New York City's consumer agency puts the minimum plainly: "All change orders to the contract must be in writing and signed by the contractor and the consumer. The change order must include the cost of the additional work, the new contract price, and the date when payment is due."16 An owner adds the lines customers look for: "Our change order template also has a line for the original project total and a line showing the new project total with the change order added to it."9
The template's change order (Part 3) fits on one page:
- Its number, the contract number, the date and the time.
- The reason: a hidden condition, the customer's request, or the inspector or code.
- What you found, where and how much, the photo numbers, and whether you showed them on site or sent them.
- What you did to make it safe while they decide.
- Two options, each with a price and the days it adds.
- The items with quantity and unit price, and the basis: contract price, fixed price, or time and materials with a cap.
- The original price, earlier change orders, this one, any allowance used, and the new contract price.
- The new completion date, and when payment for the change is due.
- Approved or declined, and both signatures with the date and time.
Where the law says changes go in writing
Any contractor can put changes in writing. Some states require it for home improvement contracts. Here are four of the states we cover, each with a link to our state page for the rest of its rules:
| State | The rule | Full rules |
|---|---|---|
| New Jersey | A home improvement contract over $500 "and all changes in the terms and conditions of the contract, shall be in writing" (N.J.S.A. 56:8-151(a)). The regulation adds that changes "shall be signed by all parties thereto" (N.J.A.C. 13:45A-16.2(a)12).17 | New Jersey contract template |
| Connecticut | "Each change in the terms and conditions of a contract shall be in writing and shall be signed by the owner and contractor" (Conn. Gen. Stat. §20-429(a)(1)(B)).18 | Connecticut contract template |
| Massachusetts | A contract over $1,000 must be in writing and hold the complete agreement (M.G.L. c. 142A §2), and departing from the plans "in any material respect without the consent of the owner" is a prohibited act (§17). The state's sample contract language: "Any modification to the original contract must be in writing and agreed to by both parties."19 | Massachusetts contract template |
| New York | A home improvement contract over $500 "and all amendments thereto, shall be evidenced by a writing and shall be signed by all the parties to the contract" (General Business Law §§770, 771).20 New York City adds the cost, new price and payment date quoted above.16 | New York contract template |
The other states we cover have their own contract pages: Arkansas, Colorado, Idaho, Iowa, Louisiana, Minnesota, Nebraska, Utah and Virginia.
When the customer isn't there
Text or email the photos and the form, and wait for it to come back signed. Some owners take a text reply: "For small job change orders, I send a text outlining the change, cost, and it says reply with yes or no to approve. That holds up legally in my state".4 Maybe it does in his. Where the law says signed by both of you, as in New Jersey, Connecticut and New York, I wouldn't bet a change order on a "yes" text. Get a signature, on paper or electronic.
If the client says no
Some will. A handyman on r/HandymanBusiness: "I have showed clients the additional damage inside the wall that could be potentially structural and they have said they didn't care, 'Cover it up!'" Others, he wrote, "take a moment to decide on moving forward with a much higher repair cost than initially estimated." On the bad mood that comes with it: "the disappointment isn't on me or my fault. They are processing the new information."21
Get the no on paper. The template's change order has a "declined" box the customer signs, saying the condition stays as found. Clause H.8 says what you won't do: cover up something unsafe, leaking or likely to fail inspection. If the job can't go on without the repair (new tile over a soft floor), say so before they choose, and write on the form what happens next.
Mold, asbestos and lead found mid-job
In all three cases, stop work in that area first. Then:
- Lead: in a home built before 1978, the EPA renovation rule covers disturbing more than 6 square feet of paint in a room (20 outside), and any window replacement or demolition of painted surfaces. Your firm must be certified, with a certified renovator on the job, who can also test the paint with an EPA-recognized kit. Iowa, Massachusetts and Utah run their own programs.22
- Asbestos: don't sample or break it. The EPA: "If in doubt, treat the material as if it contains asbestos and leave it alone." Federal law doesn't require training to remove it from a detached single-family home, "however, some states and localities do require this."23 OSHA's construction standard still covers your employees on any renovation with asbestos in it,24 and New York requires a contractor licensed by its Department of Labor.25
- Mold: over about 10 square feet, the EPA sends you to its remediation guide.26 New York requires a Labor Department license for mold remediation, assessment or abatement over 10 square feet,27 and Louisiana requires a contractor's mold remediation license once the job is over $7,500.28
One owner's contract handles the asbestos case in a sentence: "I have a line item that says if we find it we will have to remediate in the contract".29 Template clause H.7 is the longer version, and it says who pays for testing.
How to use the change order template
- Fill in Part 2 once with your prices: the rot lines from your own time and costs, the trade lines as "their price plus [ ]%".
- Paste Part 1 into your contract. On each job, fill in H.2 (what you checked, what you told them) and tick a box in H.5 (the allowance).
- At signing, say the one line, go through H.5 and Part 2, and get the initials.
- Before demo, take the Part 4 photos.
- At a find: stop, make it safe, photograph it, show them, and fill in a Part 3 change order. Nothing extra until it's signed.
- Put each change order on the final invoice as its own line, with its number.

Where Deepsel fits
The template is a document on purpose, so it works on your next job. If you'd rather do the change order from your phone, Deepsel Pro has signed change orders. "Add change order" on the job takes the find from your price book (the unit is free text, so "sheet" or "joist" works), and a negative line takes out scope you're dropping. You send it by email or copy its link, with your saved signature on it, and the customer signs it with their typed name and an on-screen signature or declines it with a reason; the time, IP address and browser are recorded. A signed change joins the job's contract total, so the job shows the original price plus the changes, and it goes onto the job's invoice, or onto an invoice of its own if the job's invoice has already gone out. On Free, the workaround is "Create estimate" on an open job that hasn't been invoiced: it starts a new estimate with the job's lines on it, the customer approves it with a signature, and converting it replaces the job's lines, so the final invoice carries the new total. Your hidden damage clause goes in the terms text, which is copied onto every estimate from your shop settings and locks once the customer approves. What it doesn't do: visit photos and job files stay internal, so text the photos yourself. The final invoice credits only the job's original deposit, so don't take a second deposit for a change. Free covers 30 estimates and 30 invoices a month for your whole team; Pro is $29 a month for unlimited estimates and invoices. Details are on the pricing page.
Free up to 30 estimates and 30 invoices a month, then $29 a month for your whole team. No credit card required.Frequently asked questions
What is a change order in construction?
A short signed form that changes the contract after it's signed: what's added or taken out, the price, and any change to the schedule. On a home job the contractor writes it and the owner approves it before the changed work starts. New Jersey, Connecticut and New York require changes to a home improvement contract in writing and signed, and Massachusetts' sample contract language says the same.
How do you fill out a change order?
Number it and tie it to the contract. Tick the reason (a hidden condition, the customer's request, or the inspector). Write what you found, where and how much, with the photo numbers. Give the options with a price and the days each adds. List the items with quantity and unit price, then the original contract price, earlier change orders, this one, any allowance used, and the new contract price. Add the schedule change and when payment is due. The customer ticks approved or declined, and you both sign and date it before the work.
What is a concealed conditions clause?
A contract clause that says what happens when you find something neither side could see before the work started: rot, damaged framing, old wiring or pipe, mold, asbestos. A good residential one says what counts, that you stop and show the owner, how the find is priced (unit prices agreed in advance, or a written price before the work), whether there's an allowance, who handles mold, asbestos and lead, and that anything you could see when you priced is already in the price. Commercial and federal contracts call it a differing site conditions clause.
Who can approve a change order?
The contractor writes it. On a home job, the person who signed the contract approves it, or someone they named in writing. Your crew lead can stop the work and show the problem, but shouldn't promise a price you haven't set.
Can a contractor charge more than the estimate?
For a change in scope, or a hidden condition your contract covers, yes: on a signed change order, before the work. For your own estimating miss, no. When a handyman who underbid a fascia and painting job asked r/handyman, the top answer was "If the error is a result of your estimation skills - you have to eat it," and he did. Damage you could see or count when you priced belongs in the original price.
How much contingency should a remodel have?
Owners on Reddit mention 10%, about 12% and 15%, and one says 20 to 30% on small residential projects. Set it by what you could see: less where you've looked at the subfloor and the crawlspace, more on an old house with a known leak. Say in the contract whether it's in the price, with the unused part credited at the end, or money the owner keeps ready.
What's the difference between a change order and a contract amendment?
A change order changes the work, price or time under the terms you already agreed. An amendment can change the terms themselves, such as the payment schedule or the warranty. On a home job treat both the same way: in writing, signed by both of you, before the change takes effect.
