Early Career and Path to Television

Mark McCullough’s journey into masonry began during his teenage years when he took his first job in the construction industry. Initially, he worked unloading watermelon and produce in Chelsea, Massachusetts, but this early employment would not last long. When his mother learned of a shooting incident near his workplace, she made the difficult decision to pull him from that job immediately. Rather than leaving her son without work, she took action by connecting him with a family friend who worked in the masonry trade, setting him up for his first position in the field the very next morning.

This pivotal moment marked the beginning of Mark’s remarkable career in masonry. What started as a way to keep a teenager out of harm’s way blossomed into a lifelong passion and profession. The decision his mother made that day would ultimately lead to his emergence as one of the most recognized masons in the country.

The Influence of Mentorship

One of the most formative relationships in Mark’s professional development came through his mentorship with an experienced mason named Dominick. At 63 years old, Dominick took the young Mark under his wing and dedicated the next two decades to teaching him the craft. This 20-year apprenticeship proved instrumental in shaping Mark’s masonry skills, knowledge, and work ethic. Under Dominick’s guidance, Mark learned not only the technical aspects of bricklaying, stone laying, and concrete work but also the physical and mental discipline required to excel in the trade. Mark credits much of his expertise, knowledge, and overall well-being to this extended mentoring relationship, recognizing Dominick’s profound impact on his life and career.

Founding MJM Masonry

Building on the foundation of his apprenticeship, Mark established MJM Masonry in the Boston area in 1992. Since founding his company over three decades ago, he has owned and managed the business with a commitment to excellence and safety. His team at MJM Masonry has completed residential and commercial projects of all sizes throughout the greater Boston area. The company has become particularly known for its work on historic projects in some of the original neighborhoods of Boston, where attention to detail and respect for architectural heritage are paramount.

Mark’s leadership style emphasizes a safety-first philosophy on every job site. He instills this critical ethos into every member of his team, ensuring that workmanship and worker welfare go hand in hand. This commitment to safety and quality has helped MJM Masonry build a stellar reputation and maintain long-term client relationships.

What Sets Mark Apart

The Artistic Nature of Masonry

When discussing what separates his trade from others in the construction industry, Mark emphasizes the artistic element inherent in masonry work. He approaches each project as a unique artistic endeavor, whether he is working with stone, marble, granite, or brick. For Mark, the challenge lies in learning how to lay individual bricks or stones and then replicating that technique consistently across entire projects. This combination of technical skill and artistic vision provides him with genuine gratification in his work. It is this deep love and respect for the craft that motivates him to return to work every day with enthusiasm and dedication.

Hidden Treasures and Interesting Discoveries

Archaeological Finds on Job Sites

One of the more delightful aspects of Mark’s masonry work involves the historical artifacts he discovers while excavating foundations, digging footings, and repairing block walls. Over his many years in the trade, he has accumulated an impressive collection of items found buried in the ground. His collection includes kitchenware such as pots, teapots, and various other items. He has also unearthed toys, hand-forged nails, old newspapers, vintage medicine bottles, aftershave containers, and even a love letter dating back to the 1940s. Each item tells a story about the past, connecting Mark to the history of the properties where he works.

Understanding Historical Disposal Practices

Mark explains that many of these buried items result from disposal practices common in the 1800s and 1900s. During those eras, homeowners would burn their garbage once a week in their yards, creating large deposits of items that either did not burn completely or failed to melt entirely in the fires. When Mark digs foundations and footings for new homes and other construction projects, he frequently unearths these remnants of past household waste. This archaeological dimension of his work adds an unexpected educational and entertainment value to his professional activities.

Masonry Traditions and Hidden Beer Cans

Mark has also discovered an interesting tradition among masons from previous generations. Historically, masons would bury a can of beer in the block cavity as they finished laying a block or brick wall. Throughout his career, Mark has found several of these cans, many of which remain in excellent condition despite spending decades entombed within concrete and masonry. These discoveries provide a tangible connection to fellow craftspeople from earlier generations and serve as a testament to the traditions that have been passed down through the masonry trade.

Personal Connection to Discoveries

Mark finds a profound personal connection to the items he discovers on job sites. He enjoys the process of carefully cleaning off each artifact to see what it is and determine its approximate age. The hunt for these buried treasures adds an element of excitement and discovery to his daily work, and he remains perpetually hopeful that each new excavation will yield something special.

Life Beyond the Workplace

When not working on masonry projects or appearing on television, Mark maintains a fulfilling personal life. He and his wife live in a suburb west of Boston in a home featuring numerous stone elements and other architectural details. The couple even maintains a few chickens in their backyard, adding a touch of rural charm to their suburban residence. This lifestyle reflects Mark’s appreciation for craftsmanship and connection to his New England community.

Mark remains active on social media, connecting with fans and fellow masonry enthusiasts through Instagram under the handle @markmcculloughtoh, where he shares insights into his work and maintains engagement with his audience.

The Impact of Television Exposure

Thanks largely to general contractor Tom Silva’s recommendation, Mark joined the cast of This Old House approximately 15 years ago. What began with small appearances and minor roles has evolved into a prominent position on one of television’s longest-running and most respected home improvement shows. The television exposure has elevated Mark’s profile significantly, allowing him to share his masonry expertise with millions of viewers while simultaneously enhancing the credibility and reach of his personal masonry business.
