New homes squeak, and Ontario has a rule about it
A new house is not immune to squeaks and it never was. Framing lumber arrives with moisture in it and gives that moisture up over the first year or two as the house dries out, which is enough to shrink the wood and loosen connections that were tight the day they were made. Ontario’s new home warranty programme addresses this directly. The Tarion Construction Performance Guidelines, currently the fifth edition updated in June 2024, include Article 2.4 on floor squeaks. The standard it sets is that some squeaking resulting from normal shrinkage of materials after construction is acceptable, but that floors shall be reasonably free from squeaks caused by movement in the floor system connections under normal seasonal indoor humidity and loading conditions. Where loose connections are causing squeaks, the guideline says they shall be repaired. Note what that draws a line between: shrinkage squeaks are excluded from the statutory warranty, while squeaks caused by movement in the floor system connections are a one-year work and materials item.
