Water Damage Types & Avgerage Costs

Everyone will have to deal with water damage cleanup one day or another. You can do it yourself with a little luck, but it can be difficult to get things back to normal. You can also get the help of a water damage expert to help you restore your home to pre-loss condition. Below we’ll go over the different types of water damage, and some of the estimated costs.



Water damage restoration involves three steps: mitigation, remediation, and restoration. Most property owners are familiar water restoration. This is a process that restores the original condition of affected materials and areas.

Water remediation includes cleaning, drying and sanitizing, as well as repairing. This crucial part of the process acts as a bridge between initial mitigation and final restoration.

There is some overlap in applied techniques but remediation is an integral part the transition between mitigation or restoration.



Mitigation is a type emergency response that addresses water damage. Water mitigation stops water damage from spreading. This helps to minimize secondary damage such as moldy drywall and buckled floors.

Water remediation is about cleanup and repairs, which set the stage for final restoration. This process creates a clean, dry environment that can be used to restore a property back to its original condition.



  • Water damage repair involves the entire process of water cleanup (removal, drying of items and structures, and restoring items).
  • Water remediation refers to the process of repairing water damage. Water remediation is the entire process of water cleanup. This includes drying out structures and items, then moving them back.
  • Water Removal refers to the act of removing water water from water-damaged areas. To remove large quantities of water, professionals use special equipment like truck mounts and commercial-grade dehumidifiers.
  • Water extraction is the same as water removal. Water extraction professionals use specialized equipment to extract large quantities of water. Water extraction can also be used to refer to water extraction in the outside world.
  • Water mitigation is the act of reducing or eliminating damage due to water intrusions in a building. Water mitigation can be used to refer to the entire water cleaning process and/or water removal.
  • Flood cleanup water from the outside has entered. Flood water can be considered to be contaminated. Most people will require professional assistance in cleaning up the affected areas, drying them, and sanitizing them.


Water damage experts are trained to deal with water damage after an emergency. The average cost is $3,292. Prices vary depending on how severe the damage was, what type of water damage it caused, and where it occurred.

Preventive and mold remediation are additional costs. However, insurance plans for homeowners who qualify will offset some of these costs. When you meet with your water damage restoration professional, make sure to document water damage.


Costs by Water Damage Category

Qualified professionals start by determining the source and assigning classifications based upon how clean the water is. This shows the amount of contamination it has had with dirt, grime and sewage.

Only licensed professionals can classify and categorize water damage. Many insurance companies do not allow DIY diagnoses to be issued. Because Category 1 damage can quickly become Category 2 damage, speed is crucial.


Category 1: Clean Water

It is easiest to dry with clean water. This service will cost you $3-$4 per square foot. Drying is only one step of the restoration process. Other repairs will depend on the material being damaged. So, the cost of repairing and vacuuming carpets is approximately $11 to $11 per sq. foot . While drywall repair costs $13 to $3 per sq. foot.

As it doesn’t have to come into contact with chemical or other fecal matter, clean water is safe for your health. However, it can cause structural damage if it isn’t checked. Drinking water is often the first to suffer from damage. These are some of the most common causes.

  • Leaky faucets Long-term leaks can go unnoticed.
  • Leaky toilet tank: Every now and again, toilet tanks leak, causing water damage.
  • Rain and sprinklers Water can often enter your home through open windows, a leaky roofing, or other cracks or holes throughout your structure.
  • Repair burst pipe: As large amounts of water can make a simple water problem more expensive, it is important to immediately repair burst pipes.
  • Water heaters As with any water source, heaters can leak or burst pipes. A typical heater will last eight to twelve years. To ensure that your heater is in good condition, call a professional like for annual maintenance.


Category 2: Grey Water

Grey water, also known as sullage, contains harmful contaminants like detergents and is more difficult than clean water to clean up. To dry the water and repair any damage, you’ll need to pay $4.50 to $6.50 per sq. foot. To repair hardwood damage due to grey water, it will cost $10-15 per square feet. While plaster damage can be repaired for $6-$19 per square foot.

Although grey water has not been in direct contact with sewage or fecal matter it has been in contact with chemicals that can pose health risks. If left untreated, grey water can be a perfect environment for mold and bacteria to flourish. These are the most common reasons:

  • Dishwasher, washing machine and other appliances that overflow can cause grey water to spill. This happens when detergent, food or clothing debris come in contact.
  • Toilets when they become clogged with urine or cleaning products, it can lead to a Category 2 grey-water repair problem. This does not necessarily mean that there is sewage backup.


Category 3: Black Water

The most difficult category to clean up and repair is black water. Black water removal costs about $7.50 to $7.50 per sq. foot. However, this price does not include the cost of repairing or replacing infected items.

Once the water is removed from your home, the prices can rise further. Since black water has been in contact with sewage, everything the water touches, including upholstered furniture, carpeting, bedding, carpeting and clothing, absorbs contaminants. In most cases, restoration is more cost-effective than replacement. Best to contact an experienced water damage restoration company.

This category also poses serious health risks because of the high levels of bacteria in black water. This type of mold damage requires the expertise of a certified mold remediation crew.


Black water flooding can be caused by several factors:

  • Sewage backups from drains or septic systems
  • Your plumbing system may be leaking or tearing.
  • Flooding due to overflowing rivers, lakes and contaminated groundwater
  • Storm surges can cause secondary flooding.


Class 1

This class is the cheapest and easiest to clean and restore. It costs around $150-400. A section of a room has suffered water damage and there is very little carpeting left. This is Class 1. An experienced homeowner can manage Class 1 water damage.


Class 2

This means that water damage has occurred in a room up to 12 inches from the wall. A $500- $1,000 class 2 water damage restoration cost is around because it takes more time for a local water damage cleanup pro to deal with, since moisture remains in the actual structure, flooring, and all nearby appliances and fixtures.


Class 3

Water damage that affects nearly all parts of a room or more, such as ceilings, walls and subflooring, is classified as a Class 3. It can cost from $1,000 up to $3,000, with the prices rising quickly as many structural materials need to be replaced.


Class 4

The cost of repairing and restoring Class 4 water damage is around $20,000 to $100,000. It results from water that has been there for a long time, such as flooding from a river or storm surge. Water damage of this type can penetrate structural materials such as stone, brick, or hardwood, and spread quickly throughout the house.
