Why New Homes Need Inspection

Many buyers assume new construction is flawless. In reality, our inspectors find defects in over 90% of new homes. Rushed construction, subcontractor errors, and missed details create problems that only professional inspection reveals.

Understanding Quebec's GCR Warranty

The Garantie de Construction Résidentielle (GCR) is mandatory for new homes in Quebec:

  • Finishing defects
  • Minor imperfections
  • Installation issues
  • Most cosmetic problems

3 Years - Building Components

  • Windows and doors
  • Roofing
  • Electrical systems
  • Plumbing systems

5 Years - Major Structural

  • Foundation
  • Load-bearing walls
  • Roof structure
  • Major systems

Critical Inspection Timing

Pre-Delivery Inspection

When: Before you take possession

Why it matters:

  • Defects documented before closing

  • Doors and windows operation
  • Plumbing fixtures and drainage
  • Electrical outlets and fixtures

Year-End Warranty Inspection

When: 11-12 months after possession

Why it matters:

  • Last chance for 1-year claims

  • Systems tested through seasons

What we check:

  • Everything from pre-delivery PLUS:
  • Cracks that developed
  • Settling issues
