Company History

Jim Minnich, of Pennsylvania, a mason by trade, came to Maine to help start a mission church in 1981.  After several years of being employed by commercial masonry contractors, Jim decided to branch off on his own and thus, KEYSTONE MASONRY INC. was born.  The word of KEYSTONE’S quality craftsmanship and exceptional work ethic quickly spread and the crew was privileged to work for some of the most elite home builders in southern, central, and western Maine.

Years of successful service went by and Jim began looking forward to retirement.  Jim not only wanted the company name to continue, but he wanted the excellent reputation of the crew and their quality craftsmanship to live on.  In 2004, Jim took a young man under his wing with plans for him to take KEYSTONE MASONRY INC. long into the future.

Our Company Today

Now, owned and operated by Jordan P. Keller, Jordan considers himself blessed to have been mentored by Jim and to now serve people all over Maine with his talent in this timeless art.  Today, KEYSTONE MASONRY INC. is a company of integrity; it still has an excellent reputation for working with homeowners, architects, and contractors to meet their special needs as well as the ability to do what it takes to get a job done right, on time, and within the budget.  From minor repairs to elaborate design and construction, every project is treated with the same importance and receives the same special attention to detail.

In this industry today, there are so many options of natural stone, cultured stone, and brick, that Jordan will gladly help guide you through your selection of medium, as well as with the design process if you so desire.  He thoroughly enjoys a challenge and he will go above and beyond to achieve the finished product you envision.
