Stone Restoration & Preservation
Restoring and preserving historic stone masonry across Ottawa–Gatineau.
Older stone buildings need a careful hand and the right materials — modern mortars can do more harm than good. Udo restores and preserves historic stonework, matching original stone and using appropriate mortars so the repair lasts and looks right.
Frequently asked
Do you match old stone and mortar?
Yes — matching material and mortar is central to good restoration. Hard modern cement on soft historic stone causes damage, so the mortar is chosen to suit the original.
