Certified conservation wallers · Working nationally
Responsible conservation of Canada's historic dry stone walls and features.
We interpret historic dry stone structures and deliver custom conservation solutions — recording, technical planning and onsite work — to the Standards and Guidelines for the Conservation of Historic Places in Canada.
What we do
Dry stone rebuilding
Heritage walls taken down, inventoried and reset on sound footings.
Heritage masonry repair
Mortared structures stabilised with matched stone and appropriate lime mortars.
Survey & documentation
Condition assessment and course-by-course records before a single stone is lifted.
The co-operative
Certified wallers, co-owners of one insured business.
Most of our members are self-employed wallers who work alone. The co-operative is what puts them on projects too large, too technical or too public for any of them to take on singly.

Featured project
Little Dutch Church, Halifax
The wall survived the Halifax explosion of 1917 and wore a concrete cap for a century afterwards. By 2020 it was collapsing in several places and leaning far enough into the street to close the sidewalk. We recorded it, took it down, and reset it in two phases — working alongside the conservator, the architect, the archaeologist and Parks Canada, and finishing on time and on budget through three hurricanes.
