The firm has already set aside provisions of £72m in latest accounts that mostly include the expected cash outflow for remediation work on legacy buildings.
Wates said it is still taking stock of the expected potential cost of rectifying buildings going as far back as 30 years under the new laws.
The firms said it would seek to recoup much of the expected outlay from insurance policies or supply chain partner insurers.
It said it hoped to recover up to £38m putting the final cost at the time of reporting at around £29m.
The increase of 18 years beyond the standard 12-year limitation period for defects will require time to fully analyse and assess, said Wates.
