About
Built around the work, not the sales pitch
ZAMA Demolition and Excavation is a heavy-work contractor operating across Toronto & the Greater Toronto Area, Ontario, covering demolition, excavation, waterproofing, machinery rental and freight.
What ZAMA does
We take on the parts of a project that involve machines, structure and ground: tearing things down, digging things out, keeping water where it belongs, supplying equipment, and moving materials to and from site. Those five categories cover most of what our clients call us for, and they are handled by the same operation rather than handed off between unrelated trades.
How we approach a project
Every job starts with an honest read of the site. Access, neighbouring structures, soil and water conditions, materials coming out, disposal routes — these decide the plan, the equipment and the price. We would rather tell you at the quoting stage that a scope is bigger than it looks than discover it halfway through.
On site, the priority is control: sequenced work, an organised work area, and a clean hand-back at the end. Demolition and excavation are inherently disruptive; a well-run job is the difference between disruption and disorder.
Quality and accountability
You deal with the people doing the work. Questions get answered by someone who has been on your site, changes get flagged before they become invoices, and the finished condition of the site is part of the job — not an afterthought.
