Oshawa Masonry Contractor · Reformity Inc.Masonry & Brick Repair in Oshawa
Oshawa's older brick homes, on the streets around downtown and through the south end, are the usual candidates for repointing, chimney repair and foundation parging. The City's permit guide spells out the split: tuckpointing mortar joints, replacing a precast chimney cap and non-structural foundation repair need no permit, while underpinning, lowering a basement floor and structural foundation repair do. That matters if you want more headroom for a basement unit: lowering the floor turns a masonry job into a permitted structural one, and we prepare the drawings for it.

Oshawa Masonry FAQ
Quick answers.
Not for tuckpointing mortar joints or replacing a precast chimney cap. Rebuilding a chimney, underpinning, lowering a basement floor and structural foundation repair all need a building permit. For other chimney repairs the City's sources differ (its permit guide lists chimney repairs, its web page exempts non-structural ones), so we confirm with Building Services before starting.
