Demolition Contractor Project (Interior + Exterior + Structural Cuts) — North York

Project snapshot

  • Location: 58 Saguenay Ave, North York, ON
  • Timeline: March–April 2026
  • Building footprint: ~1,900 sq ft per level (basement + main floor; no second floor)
  • Key constraint: demolition paced around regional utility shutoffs, especially gas
  • Scope: Full interior demolition, staged exterior demolition, garage demolition, roof removal, diamond cutting for new openings, wall-height correction, disposal + recycling, city engineer inspection.

The constraint that shaped the schedule: utility shutoffs

This job was intentionally phased because utilities had to be disconnected properly:

  • Water, electricity, and gas were shut off during the process
  • The schedule stretched mainly because we were waiting for gas disconnect from regional/city services
    That’s a common real-world factor on larger demolition/structural-modification projects—safety and approvals dictate pace.

Phase 1 — Interior demolition (full strip-out)

We started with controlled interior demolition across the main floor and basement:

  • Full removal of interior finishes and partitions
  • Contents and appliances removed as part of the clean-out (including washer, dryer, refrigerator)
  • Kitchen and bathroom areas were stripped as part of the overall kitchen demolition and bathroom demolition scope (included within the interior demo)

All interior debris and roof material were managed into 6 × 40-yard bins.

Phase 2 — Garage demolition + staging area

Early in the sequence, we completed garage demolition (block/CMU structure).
This created a dedicated staging zone for:

  • Bin placement
  • Controlled debris flow
  • Cleaner site logistics and safer load-out

Concrete/block debris from structural removals was handled separately:

  • 3 × 20-yard bins — concrete + block
  • 1 × 14-yard bin — red brick

Phase 3 — Roof removal + exterior demolition sequencing

After interior was cleared, we moved to staged exterior demolition:

  • Roof removed in controlled steps (not a chaotic drop)
  • Exterior elements were dismantled in a planned sequence to keep walls stable and the site safe
    This sequencing set up the next critical step: precision wall-height modification.

Phase 4 — Structural wall-height correction (diamond cutting)

This project required a precise final wall height. After the roof was removed:

  1. We transferred elevation/layout from the basement floor level onto the walls
  2. Then we diamond-cut the top of the walls around the full perimeter of the house
  3. Final target height: 13 ft from basement floor level (uniform all around)
wall sawing


This is demolition contractor work where concrete cutting skill matters: clean lines, accurate heights, and controlled removal.

Phase 5 — New openings (windows + doors)

We created new openings on both levels using diamond cutting:

Main floor

  • 4 new windows
  • 1 new door opening

Basement

  • 4 new windows
  • 1 new door opening
new windows


In parallel, a bricklaying team resized/closed existing openings to match the design requirements, so the structure aligned with the project drawings.

Support & inspection

Temporary support was installed where required so walls stayed stable during removals and cuts.
A city engineer inspected/accepted the work as part of the process.

Disposal & recycling (clean separation)

We separated heavy debris and recycling streams:

  • 6 × 40-yard bins — interior + roof materials
  • 3 × 20-yard bins — concrete + block
  • 1 × 14-yard bin — red brick
  • All metal recycled, including:
    • appliances (washer/dryer/fridge)
    • piping and miscellaneous metal components
disposal

Result

This was a full-scale demolition contractor scope—interior, exterior, structure, and logistics:

  • Utilities coordinated and safely disconnected (water/electric/gas)
  • Full interior demolition completed
  • Roof removed and exterior demolition staged
  • Walls cut to a consistent 13 ft height by diamond cutting
  • 10 new openings created (8 windows + 2 doors) across main & basement
  • Clean disposal plan executed with separate bins + metal recycling
  • City engineer inspection completed successfully

Demolition Contractor (North York Structural Renovation)

Real questions homeowners and builders ask before interior/exterior demolition, roof removal, and diamond cutting for openings.

A demolition contractor doesn’t just “demo.” We plan safe sequencing, coordinate utility shutoffs, manage debris logistics, and execute controlled removals—especially when roof removal, wall cuts, and new openings are part of the scope.

Yes. On this project we completed full interior demolition first, then moved into staged exterior demolition and roof removal, keeping the structure stable as the scope progressed.

The main factor was waiting for gas disconnect by regional/city services. We also coordinated water and electrical shutoffs. Safety and approvals dictate pace on these jobs.

Yes. After roof removal, we transferred layout from the basement level and diamond-cut the top of the walls around the full perimeter to a uniform 13 ft height. We also cut new window and door openings cleanly to match the plans.

We cut openings on both levels: Main floor: 4 new windows + 1 new door opening Basement: 4 new windows + 1 new door opening

Yes. We completed garage demolition (block/CMU) early in the sequence and used that cleared area for bin staging and cleaner site logistics.

We separate debris streams and plan bin logistics: interior/roof material, concrete/block, and brick can require different bins. All metal is pulled for recycling—on this project that included appliances and piping.
