iCornerstone, Inc.
iCornerstone, Inc.
iCornerstone offers design through construction services and promotes Consumer Controlled Construction as a solution to over-pricing, under performance, unrealistic allowances, and quality issues. We provide designs, labor and material specifications, accurate project costs, camera monitoring, invoice review, project accounting, and construction support that allow the homeowner to act as the general contractor easily and with a minimal time commitment. The first three carry an hourly rate of $100, while the fourth is 15% of the cost of the work as you have defined it. After a free Initial Consultation, we provide a proposal for the cost of our services. Our platform networks regulators, engineers, subcontractors, service providers, and suppliers involved in your project so that everyone knows what everyone else knows, which is the hallmark of transparency and accountability. Everyone is on the same page. Their E-folios resolve the dilemma of "If only I had known, I would have asked." Everyone benefits, and nothing like the platform exists in the industry. Clients must provide us the names of subcontractors we do not know as a means of proving to themselves we do not steer business or have a conflict of interest. This strategy helps our network grow and ensures fairness. Our free, online, Consumer E-Folio / Project Organizer / Property Profile / Research Tool will help you, even if you do not involve us in your project, comes with no strings attached, and respects your privacy. Simply register at icornerstoneinc.com and have fun using it. We claim three remarkable achievements: no client has ever gone over budget; no subcontractor has ever been overpaid or unpaid without cause; and all clients receive the highest quality at the lowest price.
"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

"I found Johnâ s service through a contractor that I didnâ t end up working with. But working with John was a nice experience. I have plans to do some reno work on my townhouse kitchen, and an important part of the job is to widen the entrance between the kitchen and the dining room. Because itâ s a townhouse structure and the management donâ t know where the original blueprint is, and they require an architectural evaluation and drawing for opening the walls. I had to hire a structural engineer/architect to do the job. John came to my house several times. He did not open the wall to probe. He looked at the structures from the basement to the kitchen and did his engineer calculation and gave me the architectural drawings according to how big I wanted to widen the entrance. I donâ t know anything about architect, but his drawing was sent to the City Hall for permit. I did change my thoughts on the all opening a couple of times, and he always responded promptly and kindly, and made changes accordingly. I had expected a much higher price from contractors for hiring an architect, but John was very reasonable, and said for a small adjustment, it wouldnâ t cost so much. I thought everything went well in our communication and the final product and the value of the work. One thing though, when the city building inspector came, he said where we wanted the wall to end was not sitting on a basement column, and that piece of end wall has to be on a column. So this means I had to put back 6 inches of the wall I had originally cut. I was a little bummed about that. I canâ t say if this is something the architect shouldâ ve known (or maybe building code is slightly different every city?), but I wish I could be better prepared or informed about this particular building code. Overall, I thought it was a good experience and I would recommend JFA Design Group."
