In 1946 Willard Mace left the Navy and settled on a farm in Rising Sun, Maryland. He found a need in the community for a business that could supply building materials. With a single truck and a shed, Mace Supply was born. Over the years, the business grew into a general building supply, hardware store and a general contractor operation for custom built homes. During the energy crisis of the early 1970’s, a special emphasis toward alternative energy heat sources came about and Mace Supply added wholesale operations in hearth products representing numerous suppliers covering a seven state area.

In 1987, Mr. Mace decided to retire and moved to Smithsburg, Maryland where he opened a small retail operation, Mace Energy Supply. From this building he soon found that retirement was not in the picture due to the high demand for these products in this area. In 1996 at age 79, Willard finally decided it was time to really retire. The business and property was sold to his stepson, William “Tad” Tweed, who incorporated the operation giving rise to Mace Energy Supply, Inc. Tad's son Louis managed the operations, making this a three generation family operated business.

The business currently sells and services top-line manufacturers in all hearth product lines. Mace Energy Supply, Inc. provides sales and service for freestanding stoves, inserts, manufactured fireplaces and manufactured chimneys.
