Had some remodeling I wanted done in my newly purchased home, Jim came to my home and worked with me and helped me figure out and decide exactly what I wanted done. He made sure I had received multiple estimates in order to be more comfortable with the price, which he came in at much lower then the other contractors who I received estimates from. Once the contract was signed the work was started almost immediately and completed in a highly efficient time period. Jim and JSF Construction were extremely professional while demonstrating and producing high quality work. I would highly recommend this company and would choose them over again in a heart beat.
