Founded in May 2018 by Helmi Ben Flah, Guaranteed offers residential plumbing, heating, cooling, and electrical service and has a team of more than 80.

“Guaranteed Service lives up to its name by delivering on its promise in every interaction —whether with customers or team members,” said Richard Lewis, CEO of Redwood Services. “Their commitment to excellence across New Jersey has earned them a deeply loyal customer base, and we’re eager to begin supporting their continued growth and success.”

The Guaranteed Service team will continue to operate the business under its current name, while Redwood will provide operational, strategic, and financial support to enhance the company’s growth, the press release said. Ben Flah will retain a significant minority ownership stake as part of the investment.

“At Guaranteed Service, we’re extremely committed to building a culture that prioritizes personal growth, celebrates team wins, and promotes mutual respect and accountability across the board,” said Ben Flah. “That strong internal foundation shines through in every customer interaction, driving the kind of experiences that lead to thousands of five-star reviews and lasting relationships. Partnering with Redwood will only strengthen our ability to grow, thrive as a business, and continue exceeding customer expectations.”
