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."

"Hess and Son was one of the best companies we’ve dealt with. We hired them to redo our deck and to build a new deck next to the old. Not only did they do an excellent job (and for a very reasonable price), but they were here every day working on the project. I think they finished our project in a little over a week and it was ALOT of work. The company is extremely responsive and sticks to their word, which is SO important. I can’t recommend them enough for your next project!"

"I was looking to build a pool house / storage shed for a very specific location. I contacted Mike about the project and am very happy I did. He was excellent to work with from start to finish. I had a design in mind and he worked with me to make it a reality. Working with Mike was so easy and seemless. He always returned calls or texts and was always on site when he said he would be. I couldnâ t be happier with the experience and the finished product. It turned out exactly as I had hoped from the design to quality of work. I highly recommend contacting Highland Home and Garden if youâ re considering a project. You wonâ t be disappointed"
