You must get a certificate of dryness, normally drying machines will remove the moisture over a few weeks. Although the surface will dry quickly, there is moisture trapped deep in sub-floor areas that will cause mould and rot.
We recommend using a company that specializes in repairing water damage and dealing with insurance companies to handle your claim. You may well have your favourite builders, but dealing with insurers takes special skill…and the patience of a saint!
Drying is normally carried out with several industrial dehumidifier machines running to bring down the moisture levels. This is all covered under your insurance, even the electricity to run them!
