Our story
A family name we put on every job.
Since 1989, Sirois & Sons has grown from landscaping and basement renovations into one of Ottawa's most trusted general contractors — without ever losing the family-run feel.
"I'm in this to help people complete their dream projects."
An Ottawa native and Concordia graduate, Pierre founded Sirois & Sons in 1989. He's the liaison between you and the team — at client meetings, coordinating trades, reviewing drawings, writing proposals — most enjoying the moment a client's wishes become a finished space that exceeds expectations.
He credits the firm's success to a team that stays: many tradespeople have been with Sirois & Sons for twenty to twenty-five years.
The principles behind the work.
Integrity
We tell you what's possible, what it costs, and what it takes — honestly, every time.
Communication
Honesty and clarity keep projects running smoothly from start to finish.
Craftsmanship
Every person on our sites is a front-line member of Sirois & Sons.
Selectivity
We take on fewer projects on purpose — so yours gets the attention it deserves.
Why clients come back, and refer.
"Their attention to quality and detail was amazing."
"Your men are exceptional, both experienced and talented."
"They brought a high level of craftsmanship and professionalism that set them apart."
"Pierre and his crew made every effort to respect the integrity of the design."
Let's talk about your home.
Three decades in, we still treat every project like it carries our name. Because it does.
