The short answer

Safety First

Before anything else, make sure the building is safe to enter. Floodwater can hide electrical hazards, slippery floors, and structural damage. Turn off power at the main breaker if you can do so without stepping into water. If you smell gas or see frayed wires, leave and call the utility company or an electrician.

Wear protective gear like rubber boots and gloves if you must go inside. Floodwater often contains contaminants, so avoid direct contact. If you feel unwell, see a doctor. Your safety matters more than saving a single vehicle or part.

Assess the Damage

Walk through the dealership with a flashlight and note what got wet. Look at the showroom, service bays, parts storage, and offices. Water can soak into drywall, insulation, and carpet, and it can also damage vehicles on the lot or in the shop. Take photos for your insurance claim, but remember that policies vary, and your insurer decides what is covered.

Check the extent of water penetration. Was it a few inches or several feet? Did it sit for hours or days? The longer water sits, the more damage it does. This assessment helps you decide what can be dried and what must be thrown out.

  • Check for standing water in all rooms and bays
  • Inspect vehicles for water line marks and electrical issues
  • Look for soaked drywall, insulation, and ceiling tiles
  • Note any fuel or oil spills from flooded vehicles
  • Test electrical outlets only after power is off
  • Document everything with photos and notes

Remove Water and Dry Out

Begin removing water as soon as it is safe. Use pumps or wet vacuums to extract standing water, then set up fans, dehumidifiers, and air movers to dry the space. Open windows if the weather allows, but be mindful of humidity. In a humid climate like Detroit's, drying can take longer.

The pros use industrial equipment to dry walls, floors, and vehicle interiors. They also monitor moisture levels to prevent hidden pockets of dampness. You can help by removing wet carpets and upholstery, but the heavy drying is right for trained professionals.

  • Use pumps and wet vacuums for standing water
  • Place dehumidifiers and air movers strategically
  • Remove wet carpet, padding, and upholstery
  • Open cabinets and drawers to let air circulate
  • Consider renting equipment if you act quickly

Salvage Vehicles and Parts

Vehicles that got flooded may be repairable, but it depends on how deep the water was and how long they were submerged. Electrical systems, engines, and interiors can suffer major damage. A mechanic can evaluate each car, but the pros can help dry and clean the interiors and undercarriages.

Parts and tools in the service area also need attention. Metal parts may rust, and electronics can fail. Sort through items and decide what is worth cleaning versus what should be discarded. Your safety and the safety of future drivers come first.

Prevent Mold and Finish Restoration

Mold can start growing within 24 to 48 hours, so drying and cleaning need to happen fast. The pros use antimicrobial treatments on affected surfaces, and they may remove porous materials like drywall and insulation that cannot be fully dried. This helps prevent health issues and further damage.

The final restoration involves repairing or replacing structural elements, repainting, and ensuring the building is safe for business. The pros handle the reconstruction and cleaning, but the timeline depends on the extent of the flood. You can also check with your insurance company about what the policy covers.

Frequently asked questions

Can flood-damaged cars be saved?

Sometimes, but it depends on the water level and how long they sat. If water reached the engine or electronics, the car may be totaled. A mechanic can assess each vehicle. The pros can dry and clean interiors and undercarriages to help reduce damage.

How long does dealership restoration take?

It varies widely. A minor flood might take a few days to dry and clean, while a major one could take weeks or months. The pros will work efficiently, but the exact time depends on the size of the building and the severity of the damage.

Do I need to throw away all wet drywall?

In most cases, yes. Drywall that gets wet can harbor mold and lose its strength. The pros can determine what is salvageable, but porous materials like drywall, insulation, and carpet usually need to be removed and replaced.
