Certified conservation wallers · Working nationally
Responsible conservation of Canada's historic dry stone walls and features.
We identify and assess historic dry stone structures and provide custom conservation solutions.

What we do
Consulting, planning and reporting
Technical planning and reporting support for historic dry stone walls and the teams that care for them.
On-site conservation and repair
Heritage walls taken down, inventoried and reset on sound footings, with matched stone where repair calls for it.
Survey, recording and 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.
Our members are self-employed dry stone wallers and stone masons from regions across the country. The co-operative allows these professionals to combine their skills and experience to complete complex projects in the public sphere.

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.
Credentials
- Standards and Guidelines
- We work to the Standards and Guidelines for the Conservation of Historic Places in Canada when assessing, planning, executing, and reporting. This is essential when working alongside other conservation professionals.
- Training
- Our members are experienced stone masons and dry stone wallers, trained in the construction and restoration of structures built without the use of mortar. Initial training is gained through Algonquin College’s Heritage Masonry program and instruction through dry stone walling associations in Britain, the USA, and Canada.
- National Historic Sites
- Provincial, municipal, ecclesiastic and institutional heritage properties.
