Who we are
Our leadership brings over 35 years of hands-on construction experience to every project. Diamond H&A Builders delivers residential construction, commercial renovations and scoped design-build work across the GTA. We work with homeowners, architects, developers, and alongside general contractors, providing reliable execution on projects ranging from private homes and home extensions to multi-unit residential and active commercial and industrial spaces.
We are often brought in for projects that need defined scopes, reliable site management, and crews that can work efficiently in occupied or time-sensitive spaces.
Our tagline is how we think about every job: Renovate. Innovate. Elevate.
