Firmin Construction worked with us from the design concept to the finished building of our new 20,000 sq. ft. manufacturing facility on Mammoth Ave. Even after completion, they have been great about making modifications, additions, and just being there when we need them helping our place of business to be better. They are a full-featured general contractor and handled all aspects of building our company's new home. Would highly recommend them to build your building.

We've used Firmin on new construction and renovation projects. These guys work as a team and go the extra mile starting in the design phase. Firmin's communication with the owner, as well as the tenant, is second to none. The communication, workmanship, and follow-up on all items (big or small) is what impressed me most. We look forward to future projects with Firmin Construction.

I wanted to express my extreme pleasure and gratitude to Firmin Construction for the work they did for me and my business. After the flood in 2016, they were in constant contact with me and have consistently gone above and beyond what I ever expected from a contractor. I wouldn't use anyone else. Thanks, Pete!

Customer Review

We recently had Firmin Construction build us a very large truck dealership located on O'Neal Ln in Baton Rouge. Our experience with Firmin was first class. They are a locally owned, family-oriented business with years and years of knowledge and experience, the kind of folks you want to do business with. They were very helpful and informative every step of the way, and their workmanship is second to none. Their knowledgeable and professional team of employees worked 1 on 1 with us on a daily basis to ensure that all of our needs were met in the most economical way possible. Thanks to Firmin Construction a long-time dream of ours has become a reality. We could not have asked for a better contractor, and we would definitely recommend them to anybody. Thanks Firmin!
