One of the most forgotten and expensive problems when it comes to both residential and commercial properties is water intrusion. It is often mistaken for general leaks or floods. Water intrusion is when water enters a building through many sources, walls, ceilings, windows, floors, and foundation leaks. However, neglecting to control it leads to mold growth and poor indoor air quality. This guide covers what water intrusion is, what causes water to get inside, how you can repair water damage, and how to prevent it.

Understanding Water Intrusion

Water damage is a problem for residential or commercial buildings. Yet, many people are unaware of what it is. This is why, if you know what water intrusion means, sources are very important for your property.

Water Intrusion Meaning and Definition

Water infiltration, water incursion, or moisture intrusion is the movement of water through the walls and entering the building from the outside. Moisture infiltration isn’t always dramatic flooding: it seeps slowly into the home, making it difficult for the untrained eye to detect until serious damage has taken place. There’s also internal water penetration; plumbing, while external sources can be rainwater or groundwater.

Water Intrusion vs Flood: Key Differences: 

Water enters your house in both cases.  Water intrusion occurs slowly and is the result of poor construction, maintenance, or minor cracks. At the same time, flooding may be sudden and is often caused by external factors such as heavy rain, storms, or burst pipes. 

• Water Intrusion: gradual, hard to notice, a result of construction issues. 
• Flooding: Sudden, clearly visible due to natural or plumbing-related issues. 

Common Causes of Water Intrusion

• Missing or damaged roof shingles
• Cracked foundation walls or basement slabs
• Poorly sealed windows and doors
• Clogged or flooded gutters
• Leaks in plumbing passing through walls and ceilings
• High groundwater levels are not being drained away

 Identifying the causes of moisture that have prompted intrusions is crucial for prevention. 

Signs and Effects of Water Intrusion

Recognizing the warning signs of water intrusion is the most crucial step in minimizing long-term damage and costly repairs. However, the sooner moisture invasion is addressed and resolved, the more likely the damage can be minimized.

How to Detect Water Intrusion in Your Home

Long-Term Damage Caused by Moisture Invasion

It can lead to:

• Structural decay in wood frames
• spread mold and mildew throughout the home
• Corrosion in metal parts
• Loss of utility through electromechanical systems
• Reduction of asset worth.

Building health risks 

Mold in constantly moist buildings can cause respiratory discomfort and reactions, as well as extreme allergies and diseases in some cases. Over time, water exposure can weaken the structural integrity of a building, compromising its safety. 

Water Intrusion Repair and Prevention

Relevant fixing and remedial actions must be done once water intrusion is recognized and detected. An individual must be prepared to prevent anything from a minor caulk rupture in the wall to a destroyed and wrinkled structural foundation. Although a few repairing actions can be accomplished using basic equipment or by a water intrusion specialist.

Water Intrusion vs. Related Terms

The term water damage can be confusing for everyone. Moisture intrusion, water ingress, and land leaks are commonly used interchangeably, but each has a unique meaning. 

Water Intrusion vs. Leaks: What’s the Difference?

Water intrusion is a broad term that includes how water enters the structure and impacts it. It also includes the route, accumulation, and damage repercussions. 

Saltwater Intrusion: a specific case

 Saltwater intrusion occurs when saline, alkalinized water moves into a freshwater aquifer due to overpumping. While it is an entirely different term from water intrusion in the building. Moreover, it is a similar term related to hydrology and water damage in coastal areas. 

Moisture Intrusion vs. Water Ingression 

• Moisture Intrusion: water vapor or high humidity 
• Water Ingression: Refers to actual liquid water entering a structure

Both terms are used in building science, but moisture intrusion can occur without visible water, such as from condensation, which is related to moisture.
