I would definitely recommend Granite State Specialties. They stayed on top of submittals, procurement, and properly staffed the project to ensure they met the schedule. They communicated any cost impacts in a timely manner.

Just wanted to thank you and the GSS team again for a great job in Providence. You completely impressed the customer with your professional performance and speedy install. We look forward having your team on the next project and highly recommend GSS to anyone acquiring the specialty work you guys provide. Thank again,

The Amherst Parks and Recreation Department was very happy with Granite State through the whole process of including the quoting, ordering and installation. Granite State was very professional and timely throughout the whole process. Thank you.
