Hiring a contractor to improve your home should be an exciting experience. Unfortunately, many homeowners in New Hampshire face the nightmare of paying a significant upfront deposit, only for the contractor to abandon the job halfway through or never show up at all. This leaves you with an unfinished home, depleted savings, and a lot of frustration.

Whether you reside in Manchester, Nashua, or Concord, the law provides clear pathways to hold dishonest contractors accountable. Under state law, contractor abandonment is treated not just as a breach of contract, but potentially as a serious violation of consumer rights. In this guide, we will walk you through the exact steps you can take to legally pursue a contractor who took your money and ran, and how an attorney from our directory can help protect your investment.

Step-by-Step Process in New Hampshire

If you have been left in the dark by a disappearing contractor, it is essential to follow a structured legal process to build a strong case. Here is how you can approach the situation in New Hampshire.

Step 1: Gathering Documents and Evidence

Before taking legal action, you must compile all proof of your relationship with the contractor. Gather your written contract, copies of cleared checks, credit card statements, and any text messages or emails regarding the project. Take clear, timestamped photographs of the unfinished work. If the contractor abandoned the job, you need to prove exactly what was completed and what was left undone.

Step 2: Sending a Formal Demand Letter

Before filing a lawsuit, generally, you should send a formal demand letter via certified mail. This letter should outline the breaches, state the amount of money you want refunded, and give a specific deadline (usually 10 to 14 days) for the contractor to respond. This serves as vital proof that you attempted to resolve the dispute outside of court.

Step 3: Filing a Complaint with the State

If the contractor ignores your demand letter, you can file a formal complaint with the New Hampshire Department of Justice, Consumer Protection and Antitrust Bureau, Concord. By filling out Form Consumer Complaint, New Hampshire, Department of Justice, Consumer Complaint Form, you alert the state attorney general's office to fraudulent business practices. While they may not take on your individual case, a pattern of complaints can trigger a state investigation.

Step 4: Filing a Lawsuit

If the damages are under $10,000, you can file a small claims case. You would fill out Form NHJB-2370-De, New Hampshire, Circuit Court District Division, Small Claim Complaint and file it at your local court, such as the New Hampshire Circuit Court, 9th Circuit - District Division, Nashua. For damages exceeding $10,000, you will need to file a civil lawsuit in a higher court, such as the Hillsborough County Superior Court Northern District, Manchester or the Merrimack County Superior Court, Concord. The statute of limitations for breach of contract in New Hampshire is generally three years, as outlined in N.H. Rev. Stat. Ann. § 508:4.

Specific Contractor Scenarios

Roofers Demanding Upfront Cash

Roofing projects are notorious for abandonment scams. A roofer may claim they need a large upfront payment to order custom shingles or secure materials. Once paid, they disappear, leaving your home exposed to the harsh New England weather. Taking money for services and failing to perform them is a direct violation of the New Hampshire Consumer Protection Act, specifically N.H. Rev. Stat. Ann. § 358-A:2. Precedent cases, such as State v. Moran, 151 N.H. 450 (NH Supreme Court 2004), have shown that contractors who habitually take money without performing work can face strict penalties under this act.

Plumbers Failing to Complete Work

When a plumber abandons a job, the consequences can be immediate and destructive, potentially leading to water damage or lack of basic utilities. If a plumber walks off the job, you may be entitled to recover not only the deposit you paid but also the extra costs incurred to hire an emergency replacement plumber to fix the mess they left behind.

Fighting Fraudulent Mechanics Liens

Sometimes, an unethical contractor will abandon a job and then file a mechanic's lien against your property, falsely claiming you owe them money. Under N.H. Rev. Stat. Ann. § 447:2, contractors have the right to a lien for labor and materials provided. However, if they abandoned the project without justification and provided no value, the lien is likely invalid. You can petition the court to have a fraudulent lien quickly removed.

How Much Does it Cost in New Hampshire?

The cost of pursuing a bad contractor depends heavily on the avenue you take:

  • Small Claims Filing Fees: Filing a small claim in a New Hampshire District Division costs $125 for claims up to $5,000 and $180 for claims between $5,001 and $10,000.
  • Superior Court Filing Fees: Filing a civil complaint in Superior Court carries a filing fee of $325.
  • Lawyer Fees: Most civil litigation attorneys in New Hampshire charge an hourly rate ranging from $250 to $450. In some strong Consumer Protection Act cases, lawyers might agree to work on a contingency basis or seek attorney's fees from the contractor.

How Long Does the Process Take?

The timeline varies based on the court system. A small claims case might be scheduled for a hearing within 2 to 4 months. However, a full civil lawsuit in a Superior Court can take anywhere from 12 to 18 months to reach a trial, depending on the discovery process and the court's current docket.
