New home and condo buyers in Ontario are covered by Tarion’s new home warranty program, which requires documenting deficiencies at specific milestones — most notably the 30-Day Form and the Year-End Form. A clean, dust-free unit makes it significantly easier to spot genuine deficiencies rather than mistaking construction residue for damage.
Why Cleanliness Affects Deficiency Reporting
Dust, adhesive residue, and construction debris can visually mask small cracks, uneven caulking, or surface defects — meaning an uncleaned unit makes it harder to conduct a thorough deficiency walkthrough for your Tarion forms.
Best Practice: Clean Before You Inspect
Before completing your 30-Day Form, a thorough clean of surfaces, fixtures, and trim lets you see the unit’s actual condition clearly — separating “this is dusty” from “this is an actual builder deficiency” that needs to be documented and submitted.
What to Look For Once the Dust Is Gone
- Hairline cracks in drywall or ceilings, more visible on a clean, matte surface than a dusty one
- Uneven caulking around windows, tubs, and countertops
- Scratches or marks on flooring and countertops that may have been covered by protective film residue
- Gaps or misalignment in cabinetry and trim
Timing Around the Year-End Form
The Year-End Form, submitted near your first anniversary in the home, is a good opportunity to also schedule a deeper seasonal clean — checking areas like HVAC vents, window seals, and grout that may show wear or minor issues worth documenting before the warranty period narrows.
