I just wanted to send a quick note about your guys and their performance during the outage here in Harrodsburg.

With the difficult customer Michael and I deal with here we needed a home run. Your guys delivered! Knocked it knocked it straight out of the park and didn’t even need to watch it leave the bat.

We were both very impressed with the teamwork and the willingness to do literally any job that needed done. This outage was dusty, cold and rainy. I didn’t hear a single complaint from anyone from your team.

Matt, Jay, Tim, Emmet, Dave and Smiley Kyle are all great guys and make on hell of a team. Please let them know how much we appreciated their hard work and dedication to completing the job successfully and safely. Maddox will be my first call going forward when I need outside help.

I would like to reach out and let you know I am very impressed with Chris and his crew.

The safety and work ethic is outstanding.
I highly recommend Maddox for any work that Air Products has.

Hiring the Maddox Industrial Group for the mechanical installation at Redox Solutions turned out to be one of the best decisions made during the construction process. The president, Scott Barker, was quite easy to work with. We had a direct line of communication, and Scott was always willing to drop by the jobsite to discuss and problem-solve with our team. Delays from his side of the coin simply did not occur.

The crew from Maddox performed the installation of tank agitators, pumps, instruments, and all process piping. All involved were very skilled in their respective responsibilities. The foreman, John Hyde, was the foundation from which the job progressed in a smooth fashion. While there were discrepancies between process drawings and what was encountered on site, solutions were quickly discussed and implemented. Decisions on piping or instrument location were made as a team with members of the Maddox crew asked to provide their input in order to arrive at the best solution. Long days did not dampen their spirits, as everyone worked together to finish the project. I would highly recommend MIG for similar mechanical projects.

I just wanted to let you know how great it was to have a contractor on site that was in charge of the whole project from start to finish.

The MM4 mixer project that John and his crew completed, recently, was very organized and he communicated with us at every junction he faced. We don’t always get that from others.

I look forward to working with you guys in the future and I will send anybody who asks if I know a good contractor, your way.

Please take some money out of petty cash and give John and his crew a raise.

Best regards,

To Whom It May Concern:

Maddox Industrial Group (MIG) has work with Poet Cloverdale on numerous occasions over the past 4 years. Most recently, they installed 400 feet of 20” piping for an EPA regulated scrubber bypass project. The project was done on time and under our budget price. Maddox was very flexible in the scope of work, even when there were changes made to the routing of the pipe. I’ve used MIG for projects, shutdowns, and day to day maintenance needs.

Below is a list of some of the projects completed at our Biorefinery by MIG:

  • 2 Concrete Pump Bases
  • 10’ x 30’ Dryer Gas Train Enclosure
  • Distillation Column Repairs
  • Numerous Drag Conveyor Repairs
  • Dryer Fan Bearing Replacement
  • Grain Elevator belt/bucket/bearing Replacements
  • Process piping repairs and projects
  • Shutdown work: capable of supply 30+ men
  • Installed 16,000 gallon Acetic Acid tank and piping

I highly recommend MIG for any pipe, mechanical, or concrete work.

To whom it may concern,

I am writing this letter with the intent of expressing the confidence I have in Maddox Industrial Group, Inc. Maddox has provided Pinnacle with interactive project planning and project improvement ideas that have saved time and money while delivering superior craftsmanship and project completion; on time and of the highest quality. I have been working with Scott Barker and the Maddox team for several years now and they have proven their ability to perform consistently and professionally time after time. The on-site crews have always been highly skilled, safety conscious, and friendly. Two of the more recent projects that I have used Maddox for is a tank farm installation that included 13 oil storage tanks for which they installed all the process piping and fitted several tanks with heat exchangers that utilize steam as their heat source. This project included running steam piping all the way to our boiler several hundred feet away and modifying not only the connections for the new piping but an entirely new steam header. Maddox also provided me with a crew and equipment to install three new pieces of production equipment that had to be placed inside an area that was already surrounded by existing equipment. They did the equipment rigging and assisted my team with mechanical installation support. Maddox is currently working on a turn key piping installations project for Pinnacle that includes the fabrication of all of the pipe supports, as well as, all of the pipe installation for a 22 tank oil storage area that began about two weeks ago. Awarding work to Maddox Industrial Group, Inc. has become something that no longer takes any thought to do. We expect a great job to be done and have yet to be disappointed.

Re: Recent Projects at Heritage Environmental Services

Dear Mr. Barker;

I would like to say thank you for your help in several recent projects and repairs at our Indianapolis treatment facility. In the past few months you have worked with me to accomplish both large and small jobs including pump installation, hi pressure piping repair, scrubber ducting repair, concrete repair, and the design and installation of our new steam heating system in the CBR building.

Your prompt response, skilled craftsmanship, professionalism, and your willingness to tackle both large and small jobs has been a great asset in the maintenance and upkeep of our facility. These attributes build upon past work experiences at the facility and I look forward to continuing our mutually beneficial relationship.

Just wanted to thank you and compliment you on the crew we had on site a few weeks ago. Aaron and his crew did an excellent job on the piping project and I believe Aaron did the tank welding, in your shop, also.  It was a very neat installation all the way around.

They were a very professional group of guys and I would welcome them back any time. We threw them a few curves, but it did not affect their attitudes at all. It affected mine, because I really like for things to go smooth and this project did not. Many thanks in getting things going as quickly as you did.

Thanks, Scott and continued success.
