What Is Water Damage Restoration?

Water damage restoration prevents further damage from occurring by utilizing water removal, moisture control and structural drying. It begins with mitigation technicians inspecting the property and assessing the level and type of water damage. If the issue is not handled immediately, what started as an easily cleanable problem can become much more severe and expensive.

Categories and Classes of Water Damage

– Categories

Category 1:

Clean water — Consists of water that comes from a sanitary source and does not pose a threat if exposed to humans.

Category 2:

Gray water — Contains water that has been contaminated in some way and is not fit for ingestion.

Category 3:

Black water — Composed of “grossly” unsanitary water, containing human/animal waste and other contaminants that can cause severe illness or death if ingested.

– Classes

Class 1 Water damage is limited to only a portion of the room, or the affected area contains little or no wet carpet that needs restoring. Only materials with low permeability have been affected.
Class 2 Slightly more damage is sustained, such as affecting an entire room or area, and there is moisture in the carpet or cushioning. There is also moisture in the structural materials, and wetness has wicked at least 12 inches up the walls.
Class 3 A large amount of damage is caused by water being absorbed by highly porous materials, resulting in ceilings, walls, carpet, etc., saturated with moisture.
Class 4 Water has caused deep saturation pockets in materials with lower permeance, necessitating specialized methods of remediation.
Once the damage has been assessed, then it is time to extract the water and dry the space.


The Four Stages of Drying

Water removal Get rid of the water in its liquid state by pumping it out of the property with water extraction systems and using specialized vacuums to remove water from porous surfaces.
Evaporation After getting rid of as much water as possible, evaporate the remaining moisture with high-velocity air movers.
Dehumidification The evaporated moisture turns into water vapor that now needs to be removed with a dehumidifier in order to prevent other absorbent materials in the room from absorbing the moisture.
Temperature control Keep the temperature of the room between 70 and 90 degrees Fahrenheit for the first 36-48 hours of drying to aid in the process. Temperatures outside of this range can hinder the process.
Water damage restoration teams use specific equipment to handle the drying process.

Common Water Damage Restoration Equipment

Air movers Portable drying devices that move a large amount of air throughout the affected area, promoting fast drying of surfaces.
Dehumidifiers Portable machines that remove excess moisture from the air, preventing the growth of mold and mildew.
Air scrubbers Machines that removed air particles that contribute to the musty smells associated with water damage.
The specifics of the water damage restoration process will depend on how long your property has been exposed to water, but there are some basic expectations you can have.

What to Expect

  • Inspection and evaluation of the water damage.
  • Emergency water extraction.
  • Setup of air scrubbers, dryers, dehumidifiers and any other necessary equipment.
  • Monitoring of humidity to determine levels of drying.
  • Providing a water damage estimate.
  • Clean up and restoration.
  • Application of antimicrobials and/or germicide.
  • Application of mold inhibitor.
  • Deodorizing.
  • Repairs, rebuild or construction services.

Why You Might Need Water Damage Restoration

The first step to getting an unexpected water event under control is water mitigation. But what kinds of scenarios might you run into with your property? Check out these examples:


  • A 40-gallon hot water tank ruptures, discharging potable fresh water.
  • An electric sump pump stops working and causes contaminated standing water.
  • A sewage backup occurs due to a clog in the plumbing pipes.
  • A severe storm causes flooding, leaving a foot of water.

If your business suffers from water damage and it does not pose a threat to your health to do so, there are a few steps you can take while waiting for a restoration team to come help:


  1. Turn off electricity to the affected area.
  2. Identify where the water is coming from, and try to stop or minimize the flow if possible.
  3. Call your insurance company and a professional restoration company.
  4. Take pictures of the damaged area for insurance purposes.
    Move light or easily movable items that would make it easier for cleaning.

How to Choose a Water Damage Restoration Company

When water damage does occur to your property, you’ll want to make sure you hire a trustworthy company that can handle the repairs. Ask companies the following questions to determine the best fit for you.

What certifications do you have?

Your restoration company should always have certifications. Look for a company that has earned the Institute of Inspection, Cleaning and Restoration Certification (IICRC), which ensures the highest standards of restoration processes and ethics from its certified companies.

What services do you offer? Your restoration company should ideally cover all aspects of the restoration project, from inspection to remediation services if necessary, reconstruction and cleanup.
What are your prices? Can the company provide recommendations? While price should not be the only factor when hiring a restoration company, it does need to be a consideration.
Do you offer emergency services? Sometimes emergencies strike at times that are not during business hours. If this happens to you, you will need a restoration company that provides 24/7 services. If the company you are considering does not provide emergency services, don’t trust the restoration company with your project. This is a sign of an ill-prepared restoration company and one that may not be prepared to handle large jobs.

Common Misconceptions

When it comes to water damage on your property, you might think there are ways for you to get around the cost of restoration, but we are here to explain why these common misconceptions can lead to further damage.

I can just air dry.

Sure, your property will eventually dry even without mitigation, but it will take a long time and cause more damage. The moisture remaining in the floors and walls will degrade the materials and compromise their condition. It also breeds mold that will quickly spread throughout the damp area. Letting your space air dry will result in more damage than hiring a water mitigation company in the first place.

Just replace everything.

You might think it will be simpler to replace all of the damaged furniture and personal belongings, but the cost of restoration is often much lower than you would expect and a professional restoration team can identify and clean salvageable items.

DIY water mitigation is manageable.

While it is possible to rent water extraction equipment, you have to make sure you are comfortable operating it and understand what each device is capable of fixing. Category 2 or 3 water damage will mean you also need OSHA-approved PPE gear. At this point, it is probably easiest to let a professional company handle the process so you can be assured your space is completely safe and dry.
