The answer
Keep the event chronology, before-during-after photos, cause reports, moisture or testing results, insurer correspondence, estimates, scopes, change orders, invoices, proof of payment, contents inventory, disposal and salvage records, permits, inspections, licensed-trade details, product and model information, warranties, completion sign-offs, depreciation recovery, settlement and unresolved issues. Retain records long enough for ownership, tax, warranty, future claim and resale needs after qualified advice.
Calgary-specific context
Photographs of open walls and hidden work often explain more to a future reviewer than a final invoice alone.
What to do next
Create one property record indexed by date, room or assembly, contractor, permit, claim item and warranty.
Verify before relying

Find the right inspection for the property.
A visual inspection cannot clear concealed defects or identify hazardous materials reliably. Ask what was inaccessible, which tests are excluded and which qualified specialist should assess the concern before work or condition removal.
