Serving all of Nashua & Surrounding Areas

Boss Wash is Southern New Hampshire's specialized expert in masonry pressure washing and sealing for brick, block, stone, and concrete surfaces—residential and commercial alike. Launched in 2025 by Keith Leavitt as a dedicated maintenance division and separate company, Boss Wash builds directly on the proven foundation of our parent company, Keith Leavitt Masonry, established in 2001 and based in Nashua, NH.

​

With more than 25 years of hands-on masonry experience, Keith Leavitt serves as founder, owner, and the on-site "solutions engineer," solving technical challenges in the field to deliver practical, lasting results. While Keith Leavitt Masonry continues to excel in historic restoration, chimney repairs,, walkways, patios, steps, concrete work, and new construction—using durable, timeless materials like antique tumbled brick, New England blended veneer stone, and local quarried NH granite—Boss Wash zeroes in on proactive care. Our sole focus is masonry maintenance: We can inspect surfaces, provide accurate estimates, perform safe pressure washing to remove dirt, mildew, moss, salt residue, and environmental buildup, apply premium sealants for protection, and handle minor repairs when needed to prevent bigger issues.

What truly sets Boss Wash apart from other pressure washing companies? We're not general cleaners—we're masonry specialists and we pressure wash masonry. Our deep background means we understand how brick, stone, and concrete behave under New England's weather, what causes deterioration, and how to protect it without causing damage. This expertise lets us catch problems early, recommend the right approach, and extend the life of your surfaces far beyond a basic clean of other pressure washing companies. "Boss Wash" says it all: with decades of real masonry knowledge behind us, we're the boss of tough masonry jobs and the first company smart property owners call for reliable, results-driven service.

We proudly serve the Nashua area as our home base, with travel available throughout Southern New Hampshire , into Northern Massachusetts, and beyond as needed.
