What their customers say

Quotes from people at J.F. Brennan Company, Inc.'s customers.

“Brennan is a great company to work with. Brennan’s work process, thoroughness and attention to detail is second to none. All of the employees and individuals onsite working on the project were very knowledgeable, polite and respectful to the town and visitors to the area. Your crews are great and they make your projects the best they can be. They know exactly what they need to do, staying at least one step ahead at all times, anticipating issues and working through them before they become an issue. They were always able to adapt when asked or needed.”

“There is no better company on the river. They are respected by the USACE and they do what they say. From a small business perspective, Brennan is the best teaming partner to have.”

“Brennan was very professional and easy to work with. They had the knowledge needed not only to finish the job, but also the experience to know how it should be done before they even started. Quality company with quality people.”

“Brennan is an excellent company to work with. Their experience, knowledge and communication skills as a contractor made working with them both enjoyable and valuable to our projects. They planned and performed above expectations, and I look forward to working with them in the future.”

“Brennan is one of the finest marine specialty contractors in North America. A century of experience in all aspects of marine-based construction: locks and dams, marinas, dredging, as well as “above waterline” concrete and construction work. They are a family-owned firm with exceptional employees who are dedicated to providing clients with a safe and quality job, utilizing innovative approaches and recognizing economic constraints. I would recommend this company without reservation.”

“Brennan has completed the tasks on time and met all deliverable deadlines, from the scope development through project execution and on-time delivery of the final products survey and report. I will use Brennan without any hesitation in future.”

“Brennan was a joy to work with. From the project manager to the field workers, I have nothing but praise for the team. We had two different crews out on-site, and the handoff from one crew to the next was flawless. They made my job easier, and I had full trust in them handling their scope of work. I highly recommend Brennan and will use them for future work.”

“The Brennan crew and project management team provided exceptional service on a difficult project. They proved to be a trustworthy supplier and provided quality workmanship. They far exceed most other contractors in the power industry and continually have their customers’ best interests as their own.”

“Brennan’s crew demonstrated the ability to make rapid adjustments when conditions warranted and did an exceptional job at communicating throughout the project. I would not hesitate to use their services when presented with a future opportunity.”

“Our project required a bathymetric and utility survey, both of which required upland tie-ins for construction design. The site conditions were highly variable regarding water depth and active versus abandoned utilities and utility burial depths. Despite these challenges, the final survey report contained the information the contractor needed to determine sediment removal and turbidity containment means and methods. The survey and report were delivered under a tight timeframe and on budget, meeting our client’s objectives. Brennan is a reliable project partner.”

“In my experience, Brennan delivers safe and quality projects, getting the results the right way. Their staff are professional, transparent, and solution-oriented.

I look forward to working with Brennan on future projects.”

The crew and management came prepared and conducted themselves professionally from start to finish. I have had experience with Brennan for pile wrap installs, inspection above and below water, construction, and pile driving, all without incident over several years. I am completely satisfied with their attention to detail and exemplary safety performance.”

“This was my first project with Brennan, and I wish I had met the team 40 years ago. The Brennan team did what they promised, delivered on time, made budgets work, cared about me as a customer, showed great concern for the success of the project, showed loyalty to our combined success, and made me feel valued! They added value where others do not. I would highly recommend Brennan to anyone needing a marine construction project. Ours was very unique, and they could not have been a better group of folks to work with!”
