Review of S.R. Freeman, Inc. by Mike T.
The overall experience was very good. The project was completed in a timely fashion with extra attention to detail and craftmanship. A lot of engineering details were unique to this job and some challenging, but Jim made it all happen !
Review of Allterra Solar by George P.
Everybody from the salesman to the office staff to the installers was professional, courteous and knowledgeable. The installation itself was awesome. I highly recommend this company.
