The Impact of Water Damage on Property Value

Water damage can have a significant impact on the value of a property. Whether it’s caused by a burst pipe, a leaking roof, or even a natural disaster like a flood, water damage can lead to various issues that affect the structural integrity and overall condition of a building. 

Today, we will explore the different aspects of water damage and its implications for property value, backed up by studies from credible institutions. So, without any further ado, let’s get right into it!

Understanding Water Damage

Before delving into the impact on property value, it’s crucial to understand what water damage entails. Water damage refers to the destruction, deterioration, or impairment of a property caused by water intrusion via a leak, overflow, or spill. 

Various things can cause it, including plumbing failures, faulty appliances, or simply inadequate maintenance of smaller leaks that eventually turn into a bigger issue. 

Assessing the Impact of Water Damage on Property Value

When evaluating the impact of water damage on the value of your property, several key factors come into play. Understanding these factors is crucial for property owners, potential buyers, and insurers alike.

Extent of Water Damage

One of the primary concerns with water damage is its impact on a property’s structural integrity. Prolonged exposure to water can damage load-bearing walls, drywall, and insulation, weaken foundations, and compromise the overall stability of the entire home or commercial building.

The more damage the property has sustained and the longer the damage has been prevalent, the more extensive and costly repairs may be necessary to restore the property to its normal condition.

Hence, those water damage restoration costs, which typically range from $1,500 to $5,000, will likely be subtracted from the initial value of the property, leading to a lower asking price.

Mold and Mildew

Water damage almost always leads to the growth of mold and mildew. Mold can spread rapidly, causing not only structural damage but also potential health problems for occupants.

The presence of mold and mildew can significantly diminish property value, as prospective buyers may be deterred by the associated health risks and the need for extensive (and expensive) mold remediation.

Here’s some hard data. Mold can devalue your property by 20 to 37%, according to the Appraisal Journal. Also, the same article says that around 50% of potential buyers walk away from the deal when they learn of a mold problem in a house.

Insurance Coverage

Water damage insurance coverage can vary a lot, depending on the policy and the cause of the damage. Most policies cover only accidental and sudden damage that happens indoors. Keywords are “accidental” and “indoors”. Both conditions have to be met.

For example, if there is a leak that wasn’t sudden but instead caused damage over an extensive period of time by going unnoticed and untreated, insurance companies will view that as preventable damage and not as “an accidental and sudden event that was out of your control”.  

But let’s also take flooding. Completely accidental and out of your control, but still not originating from indoors. The same goes for sewage backups caused by external forces like severe weather, flooding, or tree roots penetrating through sewer line pipes. 

These events often necessitate separate policies for protection. 

Whether or not an insurance company will cover the costs of repairs will play a role in the valuation of your house or place of business. 

Also, one more thing to keep in mind is that the insurance company will likely just pay for the repairs of the damage itself and not for the repairs of what caused the damage (e.g., a leaking pipe or dishwasher). 

Having a damaged dishwasher or a faulty water supply line won’t help sell your house for more, that’s for sure. 

Water Damage Category

Water damage can manifest in multiple different forms, each with varying degrees of contamination:

  • Clean water: This refers to leaks from clean water sources, such as a broken water supply line. It poses the fewest health risks but can still lead to hefty losses if not addressed in time.
  • Gray water: Refers to leaks from malfunctioning appliances or AC units. Gray water requires a little extra work when being cleaned because it can be slightly filthy. 
  • Black water: Contains harmful bacteria, all sorts of biological and industrial waste, trash, and more. It typically arises from sewage backups, flooding, or other natural disasters. This water damage category is definitely the most dangerous, and it almost always requires professional assistance.

More contaminated types of water damage are harder to clean up, leading to more expensive restoration costs, which, again, lead to lower valuations. 

Cause of Water Damage

Water damage can be triggered by various events. Common culprits include:

  • Plumbing issues: Leaking or burst pipes, faulty plumbing fixtures, or water supply line leaks.
  • Roofing leaks: Damaged or improperly installed or maintained roofs can allow water to seep into the property.
  • Appliance malfunctions: Washing machines, dishwashers, or water heaters can leak water, usually because of a clogged drain.
  • Poor drainage: Improper grading or clogged gutters and downspouts can result in water accumulation around the property, which would eventually find its way indoors. 
  • Natural disasters: Floods, storms, or hurricanes.

Different water damage causes can lead to different amounts of loss and destruction. Floods are among the worst, with flooded properties capable of losing up to 60% of their value in extreme scenarios, according to Ebbwater.

Location - Is Your Property in a Floodplain?

The location of a property also plays a big role in determining its value. In areas prone to flooding or natural disasters, AKA floodplains, properties can be devalued by around 7% due to a higher perceived risk.

Conversely, properties in low-risk areas with effective flood prevention measures may be less affected by these concerns, effectively leading to higher valuations.

Market Conditions

Property values are also influenced by market conditions and buyer preferences. In a competitive market, buyers may be less inclined to purchase a property with a history of flooding as it might require additional investments and repairs. In a buyer’s market, the impact may be less severe, but it can still influence negotiations and offers.

Mitigating Water Damage

Prevention and timely intervention are key to mitigating the impact of water damage on property values.

Taking proactive measures to prevent water damage is crucial. This includes routine maintenance, inspections, and addressing potential issues promptly. Installing proper drainage systems, maintaining roof integrity, and ensuring plumbing fixtures are in good condition can help reduce the risks.

Not only that, but these installations and regular repairs could also help boost the value of a house. 

If water damage does occur, swift action is necessary to minimize its impact. Hire a water damage restoration company so that they can handle the issue in time before it gets any worse.

Having a professional restore the damage for you is worth it because they’ll do all of the work right from the start, while you may easily make mistakes when DIY-ing due to a lack of experience, mistakes that can just waste your time and allow for water to further spread and cause more harm. 

Professionals will also take on all of the health risks associated with water damage instead of you, which is another huge benefit. 

Make sure that they help you take some water and flood-proofing measures for the future, either by doing it themselves or telling you exactly what you need to do. 

The same study by Ebbwater that we mentioned earlier also says that some buyers are willing to spend more on a property that has been properly rebuilt and flood-proofed, so take that into consideration. 


And there you have it! 

So, how much will your property’s value be impacted?

It’s hard to say without knowing which factors we’ve outlined are in play for you and which are not.
