Water Damage Restoration Cost: What to Expect and How It's Calculated

Michael Duffy • March 25, 2025

Water damage can strike suddenly, whether from burst pipes, leaking appliances, or natural disasters. When faced with such a crisis, homeowners often ask: What is the water damage restoration cost? But, the answer isn’t that simple, as no water damage is the same. The cost depends on several factors, including the extent of the damage, the type of water involved, and how quickly you waited to start the cleanup process. Today, we are going to help you understand these factors, so you can plan for your water damage restoration and avoid costly surprises.


What Impacts the Overall Water Damage Restoration Cost?

The cost for water damage restoration services varies based on several key factors. Here’s what influences the total expense:


Size of the Affected Area

The larger the damaged area, the more expensive the restoration process will be. Water damage restoration costs are typically measured per square foot, ranging from $3 to $15 per square foot. While a small leak affecting a single room may cost a few hundred dollars, extensive flooding throughout an entire home could run into the tens of thousands.


Category of Water

Not all water damage is the same, so it’s natural that tackling each different category will be charged differently. The cost of water damage restoration depends on the three categories of water damage:


  • Category 1 (Clean Water): This comes from sources like broken pipes or rainwater. It’s the easiest and least expensive type of water damage to clean up.
  • Category 2 (Gray Water): This water comes from washing machines, dishwashers, or bathroom sinks and may contain contaminants. Since extra sanitation is required, the overall cost is higher.
  • Category 3 (Black Water): This includes sewage backups and floodwaters, which are highly hazardous. Black water cleanup is the most expensive because it requires specialized equipment and extensive decontamination.


Length of Time Before Cleanup

The longer the delay, the more expensive the restoration process becomes. Standing water causes more damage by the minute, making it necessary to start the cleanup process immediately.


Mold Growth

Mold growth greatly contributes to restoration costs. Mold remediation can add anywhere from $500 to $6,000 to the overall restoration cost, depending on how much mold you’re dealing with.


What Is an Average Cost to Repair Water Damage?

Here are some typical water damage situations and what they might cost to restore:


Leaking Appliances

One of the most frequent causes of water damage are washing machines, dishwashers, or water heaters. Water damage repair costs for minor appliance leaks can range from $150 to $500. However, if water seeps all the way into the subflooring or walls, you may need additional drying and mold removal, which add to the initial cost.


Burst Pipes

This is another major issue, which can flood a home within minutes. Repairing a burst pipe itself may cost between $1,000 and $4,000. However, if walls, flooring, or electrical systems are affected, restoration costs can increase significantly.


Flooding

For homes with basements, flooding is a problem costly to repair. The cost for water extraction, drying, and structural damage can range from $2,000 to $10,000 or more. If the flooding damages electrical systems or heating equipment, expenses can climb even higher.


Sewage Backups

One of the most hazardous situations are sewage backups, also known as black water contamination. Because sewage contains harmful bacteria and viruses, professional cleanup and sanitization can’t be avoided. Restoration costs for this damage range between $3,000- $10,000, or even higher, depending on the level of contamination and the number of affected areas.


Structural Repairs

Structural repairs become necessary if water is left to sit for too long. Water can weaken drywall, rot wooden support beams, and even compromise a home’s foundation. Minor structural repairs might cost $2,500, while major renovations, including wall replacements, subfloor repairs, or extensive mold remediation, can reach $25,000 and more.


Does Insurance Cover Water Damage?

Homeowners insurance won’t cover every water damage disaster. While you can receive coverage for sudden and accidental water damage (such as burst pipes or appliance leaks), insurance may reject your claim for damage caused by neglect or unresolved maintenance issues. As far as flooding is concerned, most insurance companies have separate flood insurance policies, so always check your policy or speak to your provider before filing a claim.


Repair or Replace? Knowing What to Expect

One major decision in dealing with cost of water damage is whether to repair or replace the damaged materials:


  • Drywall may need to be fully replaced if soaked.
  • Carpets can sometimes be cleaned, but padding often needs replacement.
  • Wood floors may warp and need full removal.
  • Furniture and personal items may need content restoration or disposal.


When to Call a Professional Water Damage Restoration Company

While water damage can come out of nowhere, your home will usually announce its arrival. If you notice any of the following signs of water damage, call a professional:


  • A strong musty smell
  • Peeling paint or wallpaper
  • Warping floors or sagging ceilings
  • Mold patches on walls or baseboards
  • Unexplained water stains
