Signs & Damage

How to know if water damage is severe?

A quick self-check to tell minor water damage from severe damage, and which situations you can handle yourself versus when to call a professional.

Updated · By the Arizona Water Damage Pros team

Water damage is severe when it reaches the structure, involves contaminated water, covers a large area or has already grown mold. Minor damage stays on the surface and dries quickly. Use the checklist below to decide if you can handle it or need a professional today.

Quick self-check

Answer these questions. One "yes" means it is time to call a professional.

  • Is the ceiling sagging or bulging?
  • Do floors feel soft, spongy or uneven?
  • Did the water come from a toilet, sewer line or outside floodwater?
  • Has the area been wet for more than 48 hours?
  • Is there visible mold larger than about 10 square feet?
  • Did water reach outlets, the electrical panel or appliances?
  • Has the water spread across more than one room?

What you can handle yourself

Small clean-water spills on hard floors can usually be handled with towels, fans and a dehumidifier. The EPA says a moldy area under about 10 square feet can usually be cleaned yourself. Watch the spot for a few days. If a stain grows or a smell appears, the water went further than you thought.

When to call a professional

Call the same day if anything on the checklist applies. Severe damage gets worse quickly: wet drywall and insulation hold water, contaminated water spreads bacteria and mold can start within 24 to 48 hours. A professional can measure moisture inside walls and floors, so nothing is missed.

Start with emergency water extraction to get the water out, then water damage restoration for drying and repairs. To see how professionals classify damage, read what is considered severe water damage.

Quick answers

Common questions

Yes, for small clean-water spills on hard surfaces. Use towels, fans and a dehumidifier, and watch for stains or smells over the next few days.

Yes. It is holding water and can collapse. Keep people away and call a professional right away.

A musty smell often means mold inside a wall or under flooring. A moisture check can find the source.

If water is near outlets, the panel or appliances and the breaker is safe to reach, yes. Otherwise stay out and call for help.
