Water damage restoration can look chaotic from the outside, with hoses, fans and drywall coming off the walls, but it follows a predictable sequence. Knowing the steps helps you ask good questions, understand the estimate and know when the job is actually finished. This guide explains each stage, plus the water categories and drying classes that shape the plan. For local help, see our page on Kennesaw water damage restoration.
Stage 1: Inspection and assessment
The crew confirms the water source has stopped, checks for electrical and structural hazards, and identifies the water category. Moisture meters and thermal imaging map where the water went, often farther than it looks, under baseboards, into wall cavities and down to the floor below.
Understanding water categories
The IICRC S500 standard sorts water into three categories. Category 1 is clean water, such as a supply line. Category 2 is gray water, such as washing machine discharge, which can make people sick. Category 3 is grossly contaminated, such as sewage or floodwater from outside. Clean water can become Category 2 or 3 if it sits and picks up contaminants, which is why speed matters.
Stage 2: Water extraction
Pumps and extractors remove standing water from floors, carpet and pad. Extraction is the cheapest drying there is: every gallon pulled out mechanically is a gallon the dehumidifiers don't have to pull out of the air. See water removal and extraction.
Stage 3: Removing what can't be saved
Some materials can't be dried in a reasonable time, or are contaminated. Industry guidelines based on the S500 standard say wet insulation generally can't be dried adequately and should be removed, carpet soaked by Category 3 water must be removed, and drywall should generally be replaced if drying isn't started within 48 hours or completed within 72 hours. Removed materials should be photographed and listed for your insurer.
Stage 4: Drying and dehumidification
Air movers push air across wet surfaces and dehumidifiers pull the moisture out of the air. The S500 standard also groups jobs into drying classes, from Class 1, with little water absorbed, to Class 4, where dense materials such as hardwood, plaster or concrete hold water and need specialty drying. The class helps decide how much equipment the job needs. In Kennesaw's humid summers, dehumidification does a lot of the work. See structural drying.
Stage 5: Monitoring and documentation
The contractor returns, usually daily, to take readings and adjust equipment. Drying often takes several days. The job is done when readings show materials have reached their drying goals, not when the calendar says so. Ask for the readings: they're your proof for the insurer and your assurance against mold.
Stage 6: Cleaning and sanitizing
Surfaces that stay are cleaned, and after Category 2 or 3 water, disinfected. Contents may be cleaned on site or packed out. If mold has started, it's handled under the S520 mold standard. See mold remediation.
Stage 7: Repairs and rebuilding
Once everything is dry, drywall, insulation, flooring, cabinets, trim and paint are replaced. Repairs over $2,500 in Georgia generally require a licensed residential or general contractor, and some work needs permits. Ask who will do the rebuild and how it will be scheduled.
