Most of our masonry work is commercial masonry. We build concrete block (CMU) buildings, plus the elevator and stair shafts inside them. Brick and brick veneer go on the same buildings, over concrete block walls or framing. The concrete under the walls can be part of the job too.
MJ Masonry is a demolition and masonry contractor serving Weymouth and Greater Boston. A lot of our commercial masonry starts as a bid for a general contractor. Owners and developers hire us direct as well. Call or text (617) 838-0280, and we look at the plans and put the quote in writing.

Our commercial masonry starts with concrete block. We lay block buildings and the block walls inside them. Rebar and grout go into the walls where the engineer calls for them.
Brick and brick veneer go on the outside of the same buildings. On commercial work, the brick often goes over a block backup wall. The specs name the brick and the mortar, and we lay the wall to match.
Multi-unit buildings get the same work as commercial ones. The block goes up to the engineer's drawings, and the brick goes on to the architect's specs. Brick walls get expansion joints and block walls get control joints, where the drawings place them.
We build elevator and stair shafts in concrete block. The Massachusetts State Building Code (780 CMR) sets a shaft's fire rating by how many stories it connects. A shaft that connects four or more stories needs a 2-hour rating. Below four stories, the minimum is 1 hour, and basements count as stories.
A shaft also needs at least the rating of the floors it passes through, up to 2 hours. Interior exit stairs follow the same rules. The architect's drawings name the wall that meets the rating, and we build that wall.
The elevator layout drawings set the shaft size and the door openings. We lay the walls plumb to those numbers, so the elevator installer can set the rails. That installer needs a finished shaft, so our schedule ties into theirs.
On bid work, we take off the masonry scope from the plans and specs. The number goes back in writing, with what it includes spelled out. That gives the general contractor a clear line between our scope and the next trade's.
When a Greater Boston job runs into winter, the masonry follows cold-weather rules. Those rules start when the air drops below 40 degrees. The masonry standard also calls for a cold-weather plan, submitted and accepted before that work starts. Masonry specs often call for covering the tops of unfinished walls when work stops, until the roof is on.
Below 40 degrees, the sand or the mixing water gets heated before the mortar is mixed. New walls stay covered for at least 24 hours. Below 20 degrees, the work moves inside a heated enclosure. We price that heat and those enclosures into the bid when the dates call for them.

A teardown waits on the permit and any asbestos removal. The utilities shut off their service before our machines arrive. On a commercial job, we work to the general contractor's schedule.
Our machines take the building down, and we load out the debris as we go. On masonry jobs, the walls go up to the plans, and we go over the finished work with you.

Footings, foundations, slabs, pads, steps and landings for homes and commercial buildings. We pour the concrete that goes with our masonry work.
Learn MoreOne company can handle the teardown and the masonry that follows. We can clear an old building off a lot, then lay the block and brick for the new one.
Our own machines do the knockdowns, on a detached garage or a full commercial building. Clearing the site afterward is part of the same job.
On a teardown, you decide what happens to the foundation. When it comes out, we break it up and fill the hole.
We look at the site, or the plans on bid work, before we price anything. Then the quote comes to you in writing.
