Testimonial
“Having a dedicated project manager assigned to my new construction gave me complete confidence. If I had a question or concern about the progress of my building I could pick up the phone and contact my PM, he handled every question from architectural design and engineering to zoning and budget. My PM kept me informed and up-to-date through every phase of construction.”- Cornerstone Client, , Pittsfield, MA
“Having a 12,000sq/ft business and manufacturing facility built for my expanding company was an undertaking I was not looking forward to. I continued to hear from friends that cost and completion are two numbers that always increase through each phase of construction. They were wrong. CornerStone stayed true to the approved project budget and completed my building one full week before deadline.”- Cornerstone Client, Commercial Business, Colonie, NY
