The short answer

Find the Source First

Before you dry anything, locate where the water is coming from. Check the roof for missing shingles or holes, look at the walls for cracks, and inspect the floor for seepage. A burst pipe or a leaking water heater can also be the culprit. If you live in Frisco, keep your shutoff valve location written down.

Turn off the water supply if a pipe is the cause. For roof leaks, place a bucket under the drip and clear any debris from the gutters. If the source is groundwater, you may need to improve drainage around the garage. Acting quickly reduces the chance of structural damage.

Dry Out the Garage

Remove wet items like boxes, tools, and furniture. Use a wet vacuum to suck up standing water, then set up fans and a dehumidifier to pull moisture from the air. Open windows and doors if the weather allows. The goal is to dry surfaces within 48 hours to prevent mold growth.

Pay special attention to porous materials like drywall, wood, and insulation. These can soak up water and stay damp for days. If you have a garage with carpet or padding, lift it up to dry the floor underneath. For deep moisture, a professional water damage inspection can identify hidden wet spots.

  • Move all belongings to a dry area
  • Use a wet vacuum for standing water
  • Run fans and a dehumidifier day and night
  • Remove wet drywall and insulation promptly
  • Check behind cabinets and shelves for moisture
  • Wipe down metal surfaces to prevent rust

Assess What Needs Replacement

Some materials can be dried and saved, while others must go. Drywall that is wet, swollen, or stained usually needs to be cut out and replaced. Wood that is only damp can often be dried, but if it is warped or rotting, replace it. Insulation that is soaked should be removed.

Concrete floors can dry out, but they may need cleaning to remove stains or odors. If you have a garage with drywall ceilings, check for sagging or water marks. For a full evaluation, a water damage inspection can tell you exactly what is salvageable and what is not.

Prevent Mold and Mildew

Mold can start growing within 24 to 48 hours after water exposure. To prevent it, keep the garage dry and well-ventilated. Use a dehumidifier to lower humidity levels. Clean all surfaces with a mild detergent and water. If you see mold already, do not scrub it dry, as that releases spores.

If mold covers a large area or you have health concerns, see a doctor if you feel unwell. A mold professional can test and remove mold safely. In the garage, check corners, behind stored items, and on any wood surfaces. Regular cleaning and good airflow reduce the risk.

When to Call the Pros

Minor spills you can handle yourself, but major water damage needs professional help. If water reached electrical outlets, soaked through drywall, or caused the ceiling to sag, call local water damage pros. They have the tools to dry, clean, and restore your garage safely.

Professionals can also handle hidden moisture behind walls and under floors. They know how to remove water from hard-to-reach places and prevent secondary damage. If you are unsure about the extent, a water damage inspection can guide you. Policies vary, and your insurer decides what is covered.

  • Water reached electrical outlets or panels
  • Drywall is soft, sagging, or falling apart
  • You see visible mold growth
  • The water came from sewage or floodwater
  • You smell a musty odor that will not go away
  • The garage is attached to your home and water spread
