Why is my old brick garden wall leaning in the Glebe?

A leaning garden wall needs a mason to look at it in person before any work is planned. A mason standing at the wall can tell you what is causing it.

What a mason will examine includes the base of the wall, the condition of the mortar joints, whether the lean is uniform or concentrated in one section, and whether any of the brick or stone units have cracked or shifted.

A few things shape what the repair involves. If the wall runs along a lot line, it may count as a fence under the City's Fence By-law (2003-462), which sets a height limit of 1 m in a front yard and 213 cm in any other yard on residential property. If the wall is holding back soil on one side, that is a retaining wall, which is a different scope of work; ottawapatios.com covers retaining walls. If the lean is in a section that has to come down and be rebuilt, that can raise a structural question, and it is worth asking the City whether a permit is needed before work starts.

There are too few published prices for garden wall repair or rebuilding to quote a range. Ask any mason you speak with for a written quote that covers the area of wall involved, whether any sections need to be taken down and rebuilt, how the base will be addressed, what happens to the removed material, and what the mortar type and joint profile will be on the rebuilt sections.

Ask the City whether the rebuilt wall counts as a fence under the by-law before work starts.
