The pitch
What walked into the Den
LeakPro, run by John R. Allen out of Kingston, Ontario, fixes water leaks and wind noise on vehicles through a mobile service model.
Allen took the business to season 11 and asked for $350,000 in exchange for 35 percent, a request that valued LeakPro at roughly $1 million.
After the show
What happened next
On air, Allen struck an agreement with Jim Treliving. According to LeakPro's own company blog, the two sides then spent about six months in due diligence before parting ways, with the post noting the door stayed open for future business but the capital never landed.
The service itself kept going. A July 2026 visit to the company site showed an active mobile repair operation with a full service menu, a franchise page, and claims of more than 27 years in the trade across Canada and the United States.
Our read
The Hub verdict
LeakPro is a textbook example of why an on-air handshake is not a closed deal. The $350,000 for 35 percent ask valued the business near $1 million, and Allen agreed with Jim Treliving on camera, but the company's own blog describes six months of due diligence ending without the money. We report the deal and its collapse together, because leaving out the second half would misstate what actually happened. The mobile repair service, meanwhile, is still trading across two countries.
On-air deal with Treliving that died in due diligence
Worth knowing: The on-air handshake is public record, and so is the company's statement that it fell apart later. We report both, because the deal that unravels is part of the honest story.
