Chimney Services guide • Quincy, MA
The brick and stone chimneys in Wollaston and Squantum have stood through a century of nor’easters and salt air. They are built well, but they are not immune to any of it.
Old masonry fails in predictable ways, and the neighborhood’s mix of brick, granite, and fieldstone each has its own weak point. Here is what to look for on each.
Quincy’s old brick is generally hard-fired and durable. The lime mortar between the bricks is the part that gives out, receding a little more with every freeze cycle. Repointing with matching mortar keeps the brick doing its job.
Granite block chimneys barely weather at all, but their mortar joints still erode. The failure mode is slow and easy to miss: joints that look fine from the street but are hollow an inch deep.
Fieldstone stacks absorb more water than brick. In a coastal neighborhood that means more freeze-thaw damage per winter. Waterproofing made for masonry (not paint, not silicone) is what keeps fieldstone dry.
In Squantum especially, the side facing the water ages faster. Check that face closely; the sheltered sides can look a decade younger than the weather side on the same chimney.
A chimney that was repointed with hard modern mortar decades ago may now be spalling its brick faces. If the joints look new and the brick looks chewed, the old repair is the problem.
Walk around the chimney and compare all four sides. If one side looks markedly worse, note which direction it faces. Call (857) 220-8629 and mention the neighborhood and the stone or brick type; it changes what we look for first.
