7 Effects of Water Damage

Water is an essential part of our lives, but it can quickly become a hazard when uncontrolled moisture and flooding occur. And if you live in cities like Orlando, where the humid subtropical climate sees an average of 53 inches of rainfall annually, this risk is further magnified. With over 140,000 housing units, the potential for homes to face plumbing leaks, roof leaks, or natural flooding, especially during hurricane season, is significant. This prolonged dampness and excess water allow for the growth of mold, bacteria, and pests, which can cause illness. It also directly damages structural integrity, personal property, and electrical systems. 

Therefore, identifying and understanding the detrimental effects of water-related issues is crucial for reinforcing the prevention and prompt response when leakage or flooding does occur.

This article will examine 10 major effects of water damage to help you detect and address moisture issues early before they escalate

1. Structural Damage

Excess moisture in wood framing, drywall, and other structural materials causes swelling and warping that compromises structural integrity. When wood gets wet, it expands and distorts from its original shape. This swelling puts outward pressure on walls, floors, and other structural elements, causing them to crack, bend, or buckle.

In addition to wood, masonry and concrete foundations are gradually eroded and damaged by persistent moisture exposure. The added weight of absorbed water puts extra stress on structural elements. Floors may begin to sag, creating uneven surfaces, gaps, or even sudden collapse in the worst cases. This is especially true for houses in locations like Orlando that are more prone to rainfall and hurricanes.

For residents facing such challenges, the total Orlando water damage restoration cost can be a significant concern, emphasizing the importance of early intervention and moisture prevention. The expense of structural repairs, such as replacing rotten joists, reinforcing weakened areas, or rebuilding damaged foundations, is not just monetary. It also includes the stress and disruption of extensive repair work. Engaging with professional services early on can help mitigate these costs.

2. Mold and Mildew Growth

Damp conditions can lead to excessive mold and mildew growth inside homes and buildings. These fungi release airborne spores that can trigger allergic reactions and asthma symptoms when inhaled. They pose a particular threat to individuals with respiratory issues or suppressed immune systems, who are vulnerable to dangerous mold infections in the lungs and sinuses.

Mold and mildew thrive on cellulose-based materials, such as drywall, wood, and fabric. Walls around plumbing leaks or under-roof leaks provide ideal conditions. Wet carpets, drapes, and furniture also foster mold. To keep mold and mildew growth in check, it’s crucial to prevent excess moisture buildup through repairs and quickly drying any wet building materials or furnishings. If any large infestations occur, they mostly require cleaning or removal by mold remediation specialists to contain the outbreak and avoid health hazards.

3. Air Quality Deterioration

Water intrusion and mold growth can significantly degrade indoor air quality. Mold releases spores and mycotoxins into the air, acting as allergens and irritants. Standing water enables populations of bacteria and viruses to grow and spread through the indoor air. Damp conditions can even increase concentrations of radon and carbon monoxide, which seep from the surrounding soil and building materials.

The poor air quality resulting from water damage and mold can cause headaches, fatigue, and increased sensitivity in occupants. Children and the elderly are especially vulnerable. Asthma and allergy symptoms can also worsen. To remediate indoor air quality after water damage, it’s important to ensure proper ventilation with outdoor air, use air purification methods like HEPA filtration, and dehumidify. Maintaining good air quality requires diligent repairs to prevent excess moisture.

4. Electrical Hazards

Water and electricity together create an extremely hazardous situation. Water leaking onto electrical systems or flooding electrical components can lead to shock, fires, and equipment damage. Electrical circuits in walls or ceilings are prone to water intrusion from roof leaks, plumbing leaks, or condensation. Outlets, wiring, and appliances located below grade or near plumbing systems are also at risk of water exposure during leaks or flooding.

Any electrical components or devices exposed to water should be addressed immediately by an electrician to avoid short circuits, electrocution, and electrical fires. All affected circuits should be turned off at the main breaker panel until repairs are made. These repairs may involve replacing outlets, switches, light fixtures, and wiring to restore safety and proper function. Using electrical devices before they have fully dried out or been repaired vastly increases the chance of shock and fire, making it imperative to take action immediately following water damage.

5. Decreased Property Value

Visible water damage or mold decreases the resale value of homes. Evidence of past leaks or flooding makes potential buyers wary of ongoing issues and needed repairs, even if repaired. Signs of neglect, outdated systems, or damage to the foundation drive down value as well. Major investments are usually needed to fully remediate chronic moisture intrusion and related deterioration.

Catastrophic flooding events make properties difficult to sell until the aftermath is repaired. However, keeping up with maintenance, repairs, and mitigation measures helps retain optimal value. Fixing all water intrusion issues promptly before major damage arises demonstrates care for the home. Updated plumbing, electrical, roof, and drainage systems also add value by reducing future risk.

6. Health Implications

Water damage creates numerous health hazards beyond just mold and indoor air quality. Bacteria like E. coli, Salmonella, and Legionella thrive in damp areas and spread diseases when inhaled or ingested. Viruses are also transmitted more easily with excess moisture. The toxins released by mold and mildew growth can cause chronic headaches, nausea, and skin irritation.

Structural instability from water damage poses safety risks. Weakened building components like floors and roofs can collapse and injure occupants if the extent of water deterioration is not properly evaluated and repaired. Damp conditions are also linked to increased slips and falls. Addressing all water damage quickly minimizes related illness and injury risks.

7. Pest Infestation

Excess moisture and standing water attract pests. Cockroaches and termites are drawn to damp wood and can spread into living spaces. Mosquitoes breed in standing water. While rodents enter seeking water sources and nesting sites. Raccoons, bats, and birds may also attempt to nest in attics.

Pests contaminate food, spread diseases, and damage homes with their gnawing, nesting, and waste. Rodents chew through wood and wiring. Termites destroy wood framing and structural integrity. Keeping all areas dry through prompt repairs denies pests the water conditions they seek. Prompt pest control is advised if populations do establish following water damage.


Water damage, if left unaddressed, can wreak havoc on buildings and residents’ health and finances. Minor leaks or flooding should be dealt with immediately to control moisture and prevent the issues outlined above. In many cases, the services of water damage restoration professionals are required to properly dry out the home, remediate any dangerous mold growth, and repair damaged materials.

Staying vigilant to identify and repair any water intrusion right away is key to minimizing the detrimental effects.
