Restored heritage home

A restored heritage residence, Old Ottawa South.

The practice

Founded in 1989. Guided by one hand.

Pierre Sirois began with landscaping and basement renovations and grew Sirois & Sons into one of Ottawa's most trusted general contractors. He remains your single point of contact — at meetings, with trades, over drawings — so the work proceeds with clarity from first sketch to final detail.

We accept a limited number of commissions each year. It is the only way to give each the attention it deserves.
