It's important to prioritize safety above all. If it's safe to do so, you can start by stopping the water source if possible, removing excess water by mopping or blotting, and removing valuable items from the area. However, refrain from using electrical appliances in damp areas and do not attempt to clean up contaminated water (like sewage). Our iDry Columbus team has the necessary equipment and expertise to handle the cleanup process in a safe and effective manner. When you call us, we can provide specific advice based on your situation, guiding you on what to do or avoid until we arrive.
