Construction Rebuild & Minor Works

Rebuild and minor construction works, from general contracting to the individual trades — each carried out as a clear, step-by-step sequence.

01

What a full rebuild includes

A complete interior rebuild, from strip-out to final inspection. Each stage depends on the one before it, so the order is the work.

  1. Interior demolition

    Remove old drywall/plaster, flooring, cabinets, trim, doors, and damaged finishes.

  2. Selective structural repairs

    Repair or replace damaged studs, joists, subfloors, headers, and framing.

  3. Mould remediation and moisture repair

    Remove contaminated materials, fix leaks, and dry the area before closing walls.

  4. Framing and partition wall construction

    Build new interior walls, bulkheads, soffits, closets, and openings.

  5. Window and exterior-door adjustment/replacement

    Ensure openings are square, flashed, sealed, and airtight before interior finishes.

  6. Air sealing

    Seal gaps at penetrations, rim joists, attic transitions, and wall interfaces before insulation; this helps prevent condensation and moisture problems.

  7. Insulation installation

    Install batt, blown-in, rigid foam, or spray-foam insulation in walls, ceilings, floors, and basements as appropriate.

  8. Vapour barrier and air-barrier installation

    Install polyethylene or approved membrane on the warm side of the wall assembly, with sealed seams and penetrations.

  9. Drywall installation

    Hang, cut, and fasten drywall on walls and ceilings, including moisture-resistant board in bathrooms.

  10. Taping, mudding, and sanding

    Apply joint compound and tape in multiple coats, then sand to a smooth, paint-ready finish.

  11. Priming and interior painting

    Prime repaired/new drywall, then apply ceiling and wall paint.

  12. Flooring installation

    Install subfloor repairs, underlayment, hardwood, laminate, vinyl plank, tile, or carpet.

  13. Trim, doors, and hardware installation

    Install baseboards, casings, crown moulding, interior doors, locks, and handles.

  14. Cabinets, countertops, and built-ins

    Install kitchen/bathroom cabinetry, countertops, shelving, closets, and storage units.

  15. Final fixtures, inspection, and cleanup

    Install lighting, plumbing fixtures, electrical devices, vents, and appliances; complete municipal/trade inspections, touch-ups, and final cleaning.
