Who We ​Are

Family Owned

Stone Age Manufacturing, Inc. is a family-owned and operated business, whose background is in masonry and fireplace construction. Our modular masonry kits are designed by 3rd generation masons who possess a lifetime of scratch-building experience in all types of masonry and fireplace construction. Our first product, the Stone Age fireplace, now called the Standard Series, arose from needs in the marketplace identified through our own experiences in the field with our affiliated custom masonry installation company. From that original product, the Stone Age product line has grown to include innovative masonry kit products for every major category of outdoor living, as well as a complete line of indoor fireplaces.

Proud of Our Heritage

We take pride in our masonry construction heritage, and are committed to using our extensive knowledge and masonry expertise to produce the finest quality products available, while delivering exceptional value at a reasonable cost, and providing outstanding personal service to each of our customers.

Made in USA

Stone Age Manufacturing is located in the Tulsa, Oklahoma metropolitan area, and is proud to manufacture our products in the United States of America.
