Do not waste your time with J&J Construction and Development, they also go by J&J Carpentry. So there is no confusion, their address is 7002 Mallard Way, Cary, IL. We had worked with Jim Clarke for months on the details of our kitchen remodel and addition. We had agreed upon price and scope of work and signed a contract with them. Several days before they were to begin, he breached our contract and quit! We already had thousands of dollars of material on order, i.e. cabinets, doors, windows. That morning that they quit, Jim brought his partner Jeff to our house to review the project since they were starting in a few days. We had never met Jeff before, which we thought was odd since they are partners. Everything seemed fine and we agreed on the start date. Later that day, Jeff called us to say they will not be doing our project because "the numbers don't work" and that we should be grateful that they didn't start and walk away from it in the middle. Our guess is that either Jim is incapable of assessing costs for a large job or something bigger and better came along. We were floored. We had not paid them anything so we did not lose money specifically with them. However, since Jim strung us along for so many months and made false promises, it completely destroyed our timeline for this remodel. We had to start completely from scratch in getting all new contractors, new architectural drawings, new permits, which ultimately cost us time and money. This company cannot be trusted! They will give you the "run-around" for months and will only do your job if nothing more profitable comes up. Run from them!
