I recently had the opportunity to serve GA Johnson Construction as a vendor. I found their leadership to be organized, consistent and great communicators. - Their engagement allowed me to do an A+ job. - Special thank you to Corey and Colette for all of their time and efforts.

Corey’s crew did a bathroom remodel in my historic home. The work was done with impeccable quality, on time and for a very reasonable budget. I was remote during the remodel and always had great communication and progress reports. I will use them for future builds and remodels with no hesitation

GA Johnson Construction stepped in to help after we had some tornado damage to my antique store. They were on time, on schedule, professional, and extremely careful working around antique chandeliers and furniture. The finished on schedule and on budget as promised. Highly recommend!
