About JB Mohler Masonry

An owner-run masonry crew out of Lancaster, MA — building and repairing fireplaces, chimneys, and stonework across Central Massachusetts since 1995.

Jeff Mohler owns JB Mohler Masonry and works every job himself. If you're planning something in brick, block, or stone — a new fireplace, a chimney that finally stops leaking, stone veneer, a retaining wall — he can build it.

We're a small, hands-on company with more than 30 years of masonry experience. That's the whole pitch: you deal directly with the person doing the work, not a salesperson and a rotating crew of subcontractors.

Workmanship first

Founder and owner Jeff Mohler personally attends to every job, so the quality is consistent and the communication is straight. Whether the goal is improving or building a fireplace, repairing damage, or making sure your chimney is safe before heating season, we handle it from your first idea through completion — and we'll tell you honestly what's worth doing and what isn't.

Local roots

Jeff grew up in Groton and learned the trade in Littleton, so his roots in this area run deep. These are his neighbors' homes, and the work is done to match — every time.

Family, too

This is a family business in the most literal sense — when Jeff's not on a job site, he's Dad to Abigail, pictured here at 7.

Homeowner's photo of a chimney leaking through the ceiling
Hi — chimney's leaking into the family room after big storms. Bolton. What are we looking at?
That's a failed crown — see the cracking at the top? Contained fix if we get it before winter. Rough range: a day of work, not a rebuild. Want us to come confirm? — Jeff
