Do you work on heritage homes in Toronto?

Yes. Multiple reviews describe selective interior demolition on Cabbagetown, Corktown, Riverdale, and Annex heritage properties, with specific care for original trim, plaster medallions, stair cases, pocket doors, and hardwood. A foreman on one project discovered and salvaged original tin ceilings.

Can you handle demolition in occupied office towers?

Yes. A financial district office demolition was managed with building coordination, certificate of insurance, freight elevator booking, after-hours and weekend work scheduling, common area protection, dust containment, and daily clean-up before business hours. Building management had no complaints.

What happens if the site is flooded or fire-damaged?

The company partners with restoration firms on fire and flood scope. Work is scoped to adjuster and restoration plan, with detailed photo documentation for insurance files and precision removal to flood line or damage boundary only, leaving sound material and structure in place.

What recent reviews say

Every one of 80 reviews is five star, a perfect record that spans heritage home careful disassembly, full residential teardowns ready for foundation crews, occupied office tower tenant improvements, fire damage precision, and multi-unit apartment gutting. What reviewers consistently describe is not just demolition but site understanding, which shows up in itemized quotes, dust containment from day one, and debris cleared rather than left behind.

Mammoth's strongest profile emerges from homeowners and pros tackling renovation scope: a heritage contractor in Cabbagetown who discovers and salvages original tin ceilings, a builder's partner whose cleared lot needs no remedial work, a restoration company partner trusted with insurance-scoped fire damage, a restoration company partner trusted with insurance-scoped fire damage. Specialty work is routine here-post-tensioned parking garage de-tensioning, load-bearing wall coordination, flood-line precision removal-and the crew protects what stays with poly, floor guards, and careful stair navigation whether moving heavy cast iron or safeguarding original hardwood.
