/// About STONE

Founded by Jerry Stone, Stone Development Group, Inc., got its start in 1982 in Schiller Park, Illinois.

History Back In Time

Focused exclusively on residential remodeling projects in the beginning, the company enjoyed modest growth. The core competency of the business at the time was siding, soffits and fascia work. Later the focus changed to mainly kitchen and bathroom remodels with custom counter tops and cabinetry being a specialty of the company. Serving the greater Chicago land area the organization maintained a steady and moderately growing presence.

Clients Testimonials
  • My experience with SDG was freakin' awesome! We engaged on a project with a very aggressive schedule and all the work had to be performed outside of normal business hours (i.e. nights and weekends). The SDG Project Manager was highly effective at scheduling the contractors and coordinating all activities to complete the project on schedule and within budget. The work was top-notch and I was kept well informed of progress and plans throughout the project. I would (and often do) recommend SDG to my friends and business colleagues.

    Feel free to quote me - especially the "freakin' awesome" part!
  • John Stone and his team have always come through for me on any type of project. We have completed several commercial development projects together from concept to construction and the process has always been smooth and with minimal roadblocks to completion. I know that anything I need will be handle by Stone Development Group and I can always get ahold of John to answer any questions when needed.

  • I have been working with Stone Development Group for the past 9 years. They have completed numerous new commercial and existing expansion projects for me in that time period. SDG has always provided high quality construction, on time, and within budget. They are always willing to provide multiple crews and work excessive hours to meet our often aggressive schedules in a difficult date sensitive work environment. They have demonstrated the ability to work in a professional manner and, effectively handled problems expediently.

    I would not hesitate, and have, recommend Stone Development Group to many other expanding business owners. -DAN
  • We contracted Stone Development for our Lobby Refresh. From the beginning, they were very professional, friendly and helpful. They walked us through the whole process, from design to implementation. Even though, we were very skeptical that all of this work could be done over a weekend, they made us feel very comfortable about the process.

    Anthony Iacullo was assigned as our Project Manager and he was on-site to over-see and manage the work. It was comforting to hand over the keys to Anthony, on Friday evening, and then to have them returned Sunday evening with a brand new Lobby. I know that it was a massive undertaking to orchestrate this effort and Stone Development pulled it off without a hitch.

    Rosa and I are so happy with our new Lobby and so are our parents.
    Thank you Anthony and Stone Development for your efforts.

    Jose and Rosa Diaz, owners. -Kids R Kids #5 Orlando
