Before our professional can come in to take charge of your water damage situation, make sure to consider the weather could help or antagonise the drying efforts that will take place. Do check if rain could find itself indoors. Shut off the water at the source or minimise the amount of water that could get to your carpet.
If you have them available and cannot take out your carpet from where it is, place fans and dehumidifiers in the area where the carpet lies. That is done to promote air circulation and air evaporation. Thus, it will help your wet carpet dry quicker.
Also, consider whether your carpet has padding underneath and check if it is saturated with moisture. When this padding gets wet, mould spores may also attach to it and make it home. Mould can multiply exponentially overnight when not dealt with as soon as possible. Remove the said padding and let it dry if possible.
Do not use a regular home vacuum cleaner to suck up the water. Likely, the vacuum you have is not the kind that is used for water suction.
Do these preliminary steps so you can minimise the damage done to your carpet when faced with water damage emergencies.
