What Our Clients Say

On September 29, 1996 our church family celebrated its first service in the completed renovation process turning the North Port Mall (50,000 square feet) into a beautiful church. This was made possible because of our great God, the hard work of our people, and the leadership provided by R.J.Doerrfeld. God used Mr.Doerrfeld to save our church conservatively $500,000.00, thanks to his help we completed the work in record time!

Pastor, South Biscayne Baptist Church

I wanted to thank you for the outstanding job you did on my house remodel. Your integrity and honesty was above compare. I was at peace during the whole project knowing that I had someone that was vested in the project as if it was your own. The fact that you would take the time to go over every detail and when you could see an unexpected situation arise, you immediately brought it to my attention. The sub-contractors you hired were some of the best I have ever worked with. The house remodel is amazing and everyone who saw the before cannot get over it is the same house. I just cannot thank you enough for the "job well done".

Val Selly

RJ Doerrfeld gave us several home designs to choose from, we choose one and changed the entire floor plan. He explained how he would do everything from start to finish. He listen to what we wanted and I was able to see firsthand the building of our home. We are very happy with the materials and workmanship of everyone. This is the third house I have had built, if there were a fourth Nuline Building Systems,Inc is where I would go first.
