What Montana law says about home improvement contractors
Montana's rules for residential contractors are more specific than most homeowners realize. Title 34, Chapter 8 of the Montana Code Annotated sets out a licensing requirement, required contract terms, and consumer protection provisions that together give homeowners a strong legal footing when a contractor fails to deliver.
Mont. Code Ann. § 34-8-102 defines a home improvement contractor as any person who undertakes to construct, repair, remodel, or improve any residential building for compensation. That definition is broad. It covers general contractors, roofers, plumbers, electricians doing remodel work, and anyone else you hired to improve your home. Once a contractor fits that definition, the licensing and contract rules apply.
Mont. Code Ann. § 34-8-301 requires every home improvement contract to be in writing and to include a detailed scope of work, the total price, start and completion dates, and a description of the homeowner's cancellation rights. A verbal agreement, a vague proposal, or a one-line estimate does not satisfy this requirement. If your contractor handed you a poorly written document that skipped these terms, that omission is itself a statutory violation, and it is worth naming in your demand letter.
Mont. Code Ann. § 34-8-201 goes further, requiring licensed contractors to maintain a surety bond and a trust account for customer deposits and advance payments. When you hand over a deposit, the contractor is legally required to hold it in a protected account. Using your deposit money for other jobs, overhead, or personal expenses is not just a contract breach; it is a violation of the bond and trust account requirements and potentially actionable under Montana's consumer protection statute.
The licensing issue is your strongest argument
Before you do anything else, verify your contractor's license. Go to the Montana Department of Labor and Industry's license lookup at dli.mt.gov and search the contractor's name and business. This takes two minutes and can change the entire character of your dispute.
If the contractor was unlicensed at the time of the work, Mont. Code Ann. § 34-8-103 provides what lawyers call a complete defense. The contract is unenforceable. The contractor cannot sue you for unpaid amounts, and any amounts you already paid for substandard or unfinished work become recoverable.
If the contractor was licensed, you're still in a strong position. Licensed status does not excuse contract breaches, defective work, or abandoned projects. It just means you're arguing the merits of performance rather than the threshold licensing issue.
Either way, that license check result belongs in your demand letter. A contractor who knows you've pulled their license record is on notice that you understand the regulatory framework. That changes the negotiation.
What you can actually recover
Montana gives homeowners several layers of potential recovery for a contractor dispute. You're not limited to what's in the contract.
Your baseline recovery is actual damages: the cost of the unfinished or defective work, the amount you paid for work that was never done, the cost of hiring a replacement contractor to finish or repair the job, and any consequential losses you can document (water damage from an incomplete roof repair, for example).
On top of that, if the contractor's conduct qualifies as an unfair or deceptive practice under Mont. Code Ann. § 30-14-101 et seq., you can add up to $5,000 per violation as statutory damages. The Montana Unfair Trade Practices Act defines deceptive practices broadly. False representations about the scope of work, failure to disclose that the contractor wasn't licensed, high-pressure tactics that led you to sign a deficient contract, and using your deposit without holding it in trust all fit comfortably within § 34-8-403's list of prohibited practices.
If you prevail on a UTPA claim, the court can also award reasonable attorney's fees. Even if you don't hire an attorney, the threat of a fee-shifting award is meaningful leverage in a settlement demand.
Typical recovery in Montana contractor disputes runs from $1,500 for smaller unfinished-work claims to $15,000 for larger renovation projects gone wrong. If your claim exceeds $7,000, note that Justice Court's small claims division is capped at that amount. Claims above the threshold require District Court filing, which is outside the scope of this guide.
How long you have to act
For a written contract (which Montana requires for home improvement work), Mont. Code Ann. § 27-2-203 gives you four years from the date the cause of action accrues. For most disputes, that clock starts when the contractor abandoned the project, delivered defective work, or stopped responding to requests for the refund.
Four years sounds like a long window, and it is, compared to many states. But waiting has real costs that the statute of limitations doesn't capture. Contractor businesses dissolve. Subcontractors' contact information gets stale. Witnesses' memories fade. Photos taken the week after a contractor walks off a job are worth more than ones taken two years later when you finally decide to act.
The UTPA claim has the same four-year window under Mont. Code Ann. § 27-2-209 for real property improvement work. If the work was oral and undocumented, the window shrinks to two years, which is one reason why the written contract requirement matters: a contractor who kept the agreement verbal may be trying to shorten your legal options.
Act before the memory of the work is gone. The demand letter costs almost nothing to send and locks in the record while everything is still fresh.
Evidence you need to gather before writing the letter
A demand letter is only as strong as the documentation behind it. Gather the following before you draft a single word.
The contract. The signed home improvement contract, any amendments, and every change order. If the contractor never provided a written contract as required by § 34-8-301, document that fact. The absence of a compliant written agreement is itself leverage.
Proof of payment. Bank statements, cancelled checks, Venmo or Zelle records, or wire transfer confirmations showing every dollar you paid, including any deposit. Note the dates and amounts.
License verification. A screenshot or printout of the DLI license lookup result, showing either the contractor's current license status, a lapsed license, or no license on record. Print the page with the URL and date visible.
Photos and video. Dated photos of the work as completed, any defects, and the condition in which the contractor left the site. If the roof isn't done, photograph it. If the tile work is cracked, photograph it. If the subfloor is exposed because they walked off mid-project, photograph that too.
Written communications. Every text message, email, and voicemail transcript. Export and save them. A contractor who stopped responding to your texts after you complained about the work is showing you what the court will see.
Quotes from replacement contractors. If you've already gotten a bid to finish or repair the job, bring that document. It converts your claim from an abstract number to a documented, line-item repair estimate.
The bond and trust account. If you paid a deposit and the contractor did not hold it in trust as required by § 34-8-201, document the deposit payment and the absence of any trust account disclosure. This can support a UTPA claim independent of the quality-of-work dispute.
Writing a Montana contractor demand letter that works
A demand letter for a Montana contractor dispute serves one immediate purpose: to put the contractor on written notice that you know the statutes, you have documented the violations, and you are ready to file in Justice Court if the matter is not resolved. The letter is not a complaint. It is a settlement offer with a deadline attached.
Keep it to one page. Every paragraph should do work. Here is what the letter must include.
Opening. State the parties, the project address, the contract date, the scope of work contracted for, and the total amount paid. Be precise. "I paid you $8,400 by check and Venmo between March 3 and April 15, 2025, for a kitchen renovation at 114 Elk Trail, Billings, MT" is more useful than "I hired you to redo my kitchen."
The breach. Name specifically what went wrong: abandoned project, defective work, unreturned deposit, failure to start on the contract start date. Tie each failure to the contract term that required something different.
The statutory violations. This is what separates a form letter from a legally effective demand. Cite Mont. Code Ann. § 34-8-103 if the contractor was unlicensed. Cite § 34-8-301 if the contract was missing required terms. Cite § 34-8-201 if the deposit wasn't held in trust. Cite § 34-8-403 and Mont. Code Ann. § 30-14-101 et seq. if there was misrepresentation or a deceptive practice. Name the UTPA penalty of up to $5,000 per violation.
The demand. State the exact dollar amount you are demanding and how you calculated it: refund of deposit, cost to complete, documented repair estimate, any additional losses. Include the UTPA statutory damages you could seek on top of actual damages.
The deadline. Fourteen calendar days from receipt is standard. Fourteen days is enough time for the contractor to consult anyone they need to and respond, but short enough that it signals you're not going to let this drag out.
The next step. Tell them clearly what you will do if the deadline passes: file a claim in Justice Court (or District Court if above $7,000), seek the UTPA statutory penalty of up to $5,000 per violation, and seek attorney's fees under the UTPA. Make it factual, not threatening. The facts are threatening enough.
Send the letter by USPS Certified Mail. Delivery confirmation creates a record of receipt that is admissible in court. Keep the tracking number.
If the deadline passes without a response
If the deadline passes and the contractor hasn't paid, responded, or offered a reasonable resolution, file a Montana small claims case against your contractor in Justice Court, which handles claims up to $7,000. For disputes above that threshold, District Court is the correct venue.
The demand letter you sent by USPS Certified Mail becomes your first exhibit. A contractor who ignored a statute-citing certified demand is a contractor who will have a hard time explaining their conduct to a judge. Most do not let it get that far. When they understand that the UTPA penalty and fee-shifting provisions are on the table, settlement happens quickly.
What to expect after you send the letter
Most responses arrive within the first seven to ten days. Contractors who know they've breached the contract usually don't want a court date, especially when the letter cites the licensing requirement and the UTPA penalty. You'll typically see one of three outcomes.
Full payment or a reasonable offer. The contractor sends a check or proposes a settlement that covers most of your documented loss. This is the best outcome. Review any settlement agreement carefully before signing. Make sure it covers all damages and contains a release that you're comfortable with.
A partial offer or counterclaim. The contractor agrees they owe something but disputes the amount. This is a negotiation. If the offer is close to your documented loss and the difference doesn't justify a court filing, consider it. If the gap is large, respond in writing with your counter and hold the deadline.
Silence. The contractor doesn't respond. This is common with contractors who have multiple disputes in motion. It does not mean your claim is weak. It means you file. A certified mail tracking record showing delivery plus a non-response is a clean record for a default or summary ruling.
In each case, keep your paper trail organized and intact. You'll need it if the case goes to Justice Court, and having it organized from the start is what makes the court process fast when it does.
