Ottawa's Trusted Contractor Since 1989
For over three decades, Sirois & Sons has built its reputation one referral at a time, growing into one of Ottawa's most trusted general contractors for renovations, additions, and builds of every size.
A Reputation Built on Referrals
Sirois & Sons got its start in 1989 as a small team focused on exterior landscaping and basement and bathroom renovations. As our skills, sub-trades, and client base grew, so did our reputation as a dependable Ottawa general contractor — and much of that growth still comes the same way it always has, through neighbours referring neighbours across Ottawa, Nepean, and Kanata. Honesty, clarity, and communication guide every renovation and construction project we take on, which is why our project signs keep making their way from lawn to lawn.

View →One Contractor, Every Service
Rather than specializing in a single type of project, Sirois & Sons has built the in-house experience and trusted sub-trade relationships to handle nearly any renovation, remodel, or build a homeowner or business needs. Our work spans home renovations and additions, kitchen and bathroom remodels, decks and patios, and barrier-free construction for elderly and disabled clients, alongside commercial fit-ups, home inspections, and special projects across Ottawa and the Ottawa Valley. That range means clients can rely on one contractor for a single room today and a full addition or commercial build down the road.
Award of Excellence
32 Cameron Avenue
This award recognizes the addition at 32 Cameron Street, a designated heritage building. The contemporary expression of the addition is distinguishable from the historic building while respecting the height, scale and materials of the original house.
Pierre Sirois, Sirois and Sons
Led by Pierre Sirois & a Trusted Team
Pierre Sirois, an Ottawa native and Concordia University graduate, leads Sirois & Sons as its primary contact and hands-on project manager, working directly with clients to guide them through the renovation or construction process from start to finish. Every carpenter, tradesperson, and labourer on our job sites is treated as a front-line representative of the company, and we intentionally limit how many projects we take on at once. That discipline is how Sirois & Sons has completed hundreds of renovations and additions throughout Ottawa while giving every client the specialized attention their project deserves.
