O’Brian Interior Systems offer top-of-the-line renovation and finishing services to let our customers transform their dream spaces like never before. Established six years ago in Toronto, and on a scale that expands across the Greater Toronto Area, our belief in being unique has allowed us to master every service that we provide.

As a sole proprietorship, we have defied the belief that a single man cannot run a construction business. Our focus on client satisfaction has made us grow through the years into a reliable enterprise. O’Brian services bring homeowners, office owners, and real estate companies across Toronto to have the best options for renovations and finishing at their disposal. Our expert crew makes us what we are and helps us abide by the business interests that we laid out years ago. At O’Brians we ensure that all projects are completed in-house, however well assigned to subcontractors these projects are allowed a ‘handover’ only after a thorough inspection like all others.
