The short answer

Stop the Water Source

Your first move is to stop more water from coming in. If the leak is from a pipe, turn off the main water valve. If it is from a roof, place a bucket under the leak and clear any debris from the roof if it is safe. For an appliance, unplug it and shut off its supply line.

Find your shutoff valve now, before an emergency. If you live in Detroit, keep that location written down. Knowing where it is saves precious minutes. If you cannot find it or the water is from a natural source like a flood, focus on protecting your belongings and call for help.

  • Turn off the main water valve if a pipe burst.
  • Unplug appliances near the water.
  • Move furniture and rugs away from the wet area.
  • Place buckets or pans under active roof leaks.
  • Turn off electricity in affected rooms if safe to do so.

Remove Standing Water Quickly

Standing water soaks into drywall, wood, and carpet fast. Use towels, mops, or a wet vacuum to pull up as much as you can. The longer water sits, the more damage it causes. Work from the edges of the puddle toward the center to avoid spreading it.

If you have a sump pump or a shop vac, use it. For large areas, you might need to open windows and doors to let air move. Do not use a regular household vacuum on wet floors, as it poses a shock risk. Dry surfaces as much as possible in this first hour.

Protect Your Belongings

Move books, photos, electronics, and other valuables to a dry spot. Lift furniture off wet carpet using blocks or foil to prevent stains. Hang wet clothes and drapes to dry, and remove area rugs if you can. Quick action can save items that would otherwise be ruined.

Take photos of the damage for your records. This helps later if you file a claim. Do not throw away damaged items yet, as your insurance company may want to see them. Keep a list of what you moved and where, so you can track everything.

Dry Out the Area

Set up fans and dehumidifiers to pull moisture from the air. Open windows if the outdoor humidity is lower than indoors. In a humid climate like Detroit's, drying can take longer, so start early. Point fans at wet walls and floors to speed up evaporation.

Remove baseboards and drill small holes in walls to let trapped water escape, but only if you are comfortable doing so. This helps prevent mold growth. For serious water in walls or ceilings, you may need to cut away wet drywall. That is where the pros step in.

Call the Right Help

Your insurance company should be notified soon. Policies vary, and your insurer decides what is covered. Ask what documentation they need. Then call local water damage pros who can assess the situation and begin the drying and repair process. They have industrial equipment that homeowners usually do not.

Do not wait to make these calls. The first hour sets the stage for how much damage occurs. Pros can handle water extraction, dehumidification, and mold prevention. For specific issues like drywall or carpet, they can guide you on the next steps. Acting now reduces long-term problems.

  • Call your insurance company to start a claim.
  • Contact the pros for an assessment.
  • Ask about drying equipment you can rent.
  • Check with a mold professional if mold appears.
  • Keep receipts for any supplies you buy.

Water damage does not wait

Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Frequently asked questions

Should I turn off the electricity if there is water?

Yes, if it is safe to do so. Water and electricity are a dangerous mix. Go to the breaker panel and shut off power to the affected rooms. If the panel is wet or you are unsure, call an electrician before touching anything.

Can I use a regular fan to dry the area?

Yes, a regular fan can help circulate air and speed drying. Place it near wet surfaces but keep it away from standing water. For better results, use a dehumidifier to pull moisture from the air, especially in humid conditions.

How do I prevent mold in the first hour?

Mold starts growing within 24 to 48 hours, so the first hour is critical. Remove standing water, dry surfaces with fans, and lower indoor humidity. If you see mold starting, contact a mold professional to handle it safely.
