Warranty periods in construction: a guide for builders
After the keys are handed over, the most sensitive phase of the builder–client relationship begins: the warranty period. Warranty periods in construction vary by system (waterproofing, installations, frames, finishes) and are detailed in the owner's manual delivered by the builder, following local law and standards.
Warranty and maintenance go together
Coverage assumes the preventive maintenance required by the manual was performed and recorded. Without that record, a ticket dispute becomes word against word. Planned, documented maintenance, the discipline behind durability standards such as CSA S478, is what preserves the warranty.
The risk of untracked service
Tickets by email and phone get lost, with no status and no evidence of the service performed. For the builder, that means rework and legal fragility; for the client, lack of transparency.
A systemic ticket channel
A technical assistance system records each request with date, status (open, in progress, done), service rating and management reports: the complete history that protects deadlines and warranties for both sides.
Frequently asked questions
What are the warranty periods in construction?
They vary by building system and are detailed in the owner's manual delivered by the builder, with specific periods per item (waterproofing, installations, frames, etc.) as set by local law and standards.
Can the warranty be voided?
Yes. If the preventive maintenance required by the use manual is not performed and recorded, the builder may deny coverage for the item, which is why records matter for both sides.
How does the builder prove service within the deadline?
With a systemic ticket channel: each request is recorded with date, status and evidence of the service, building the history that supports the builder's position in a warranty dispute.
