State investigators say a Missouri contractor cashed in on chaos after last year’s tornadoes, taking big deposits from storm-weary homeowners and then leaving them with half-finished projects and empty wallets.
Jacob Kaestner, owner of JK Exteriors, has been charged after what prosecutors describe as a pattern of collecting upfront money for exterior repairs and then failing to deliver the promised work or refunds. Court filings in Jefferson County outline a series of alleged no-shows and partial jobs that left multiple clients, including tornado victims still trying to rebuild, stuck in limbo. Local officials say the case underscores just how vulnerable storm-damaged homeowners can be when they are desperate to get repairs started.
State Alleges A Targeted, Wide-Ranging Scheme
The Missouri Attorney General’s Office says Kaestner is facing 16 counts of deceptive business practice and seven counts of financial exploitation of an elder or disabled person. According to prosecutors, 16 consumers lost a combined $131,886 between March 2025 and March 2026.
Many of those customers were victims of the March and May 2025 tornadoes, according to probable-cause documents from the Attorney General’s Office, which say storm-damaged homeowners signed repair contracts and paid deposits only to see little or no work done. The charges were filed in Jefferson County Circuit Court, according to First Alert 4.
Attorney General Steps Up Enforcement
The case is part of a broader push by the Attorney General’s consumer-protection team, which has been pursuing contractor fraud around Missouri as communities continue long-term storm recovery. The office has sought both restitution and criminal charges in multiple counties and is again reminding residents to hold on to every scrap of paperwork.
Victims in the Kaestner matter are being urged to preserve contracts, receipts, photographs and any written communication tied to their projects. Homeowners who believe they were scammed can submit documentation using a printable consumer complaint form available through the Missouri Attorney General's Office.
Allegations In The Probable-Cause Statement
According to the probable-cause statement reviewed by reporters, Kaestner typically required substantial down payments before work began, then allegedly failed to provide the agreed-on materials or labor and did not issue refunds when projects stalled out.
One April 2025 case describes a homeowner who paid for a roof replacement, received less than half of the contracted work and did not get a $25,675 refund that was allegedly owed. In another case from July 2025, a customer reportedly lost $18,237 after paying a deposit and seeing no work performed at all.
The warrant request further alleges that Kaestner defrauded customers not only in Jefferson County but also in Franklin and St. Charles counties, and notes that he has previously been named as a defendant in civil lawsuits. His bond is set at $50,000, according to First Alert 4.
What The Charges Mean
Among the most serious counts are those tied to financial exploitation of an elderly or disabled person, a crime that Missouri law spells out in detail and that can carry felony penalties depending on how much money is involved. Larger losses can bring significantly tougher sentencing.
State guidance explains that this offense covers using deception, intimidation or undue influence to obtain control of an elder or disabled person’s money or property. In cases where guilt is proven, prosecutors can seek both restitution and criminal penalties. The department that investigates elder abuse and exploitation provides public information on how these statutes are applied by law enforcement and protective services through the Missouri Department of Health and Senior Services.
How Homeowners Can Protect Themselves
Consumer advocates say that in the emotional wreckage after a storm, it is easy for slick contractors to take advantage of people who just want their homes livable again. To reduce the risk of being burned, experts urge homeowners to be especially skeptical of unsolicited door-to-door pitches, to avoid paying large amounts in cash upfront and to get multiple written estimates before signing anything.
Detailed contracts, clear timelines and thorough receipts are crucial if something later goes wrong. The Better Business Bureau keeps extensive guidance and a Scam Tracker for people who suspect they have run into fraud, and offers checklists for vetting contractors.
Anyone who believes they were targeted in this or a similar scheme is encouraged to preserve all paperwork, contact local law enforcement and consider filing a consumer complaint with the Attorney General’s Office so investigators can review the evidence.
