Routine maintenance tasks that prevent water intrusion and preserve home value

What Does Water Intrusion Mean?

Water intrusion refers to the unintentional but unwanted entry of water into a building, such as your home. It penetrates interior areas that should stay dry at all times, sometimes even inundating them.

What's the Difference Between a Leak and Intrusion?

Leaks usually refer to water or fluids escaping from plumbing systems and components. Examples include:

• Plumbing pipes
• Faucets
• Water storage tanks
• Toilet tanks

Leaks can be a specific type of water intrusion, as they can "intrude" into your home from a leaking pipe behind a wall. They're also common. The U.S. Environmental Protection Agency notes that nationwide, household leaks can waste up to a trillion gallons of water each year.

Water intrusion, on the other hand, refers to water that comes from a source, usually an external one, and enters or penetrates the building. It can be water generated by heavy rains, rising groundwater, or melting snow.

In most cases, well-designed homes account for the possibility of water intrusion, which is why architects, engineers, and builders incorporate many layers of defense when constructing homes. They add sloped grading, roofing drainage systems (including gutters), and foundation waterproofing to the home's design.

However, even the most well-designed homes can still experience leaks and intrusion due to neglect and a lack of preventative care.

How Can You Avoid Water Intrusion While Saving Money and Preserving Home Value? 

Water intrusion can lead to significant water damage that gives rise to mold growth. Mold growth, unfortunately, is more than just an "ick" for many people; it can also lead to health concerns. The U.S. CDC notes that problems like allergies, asthma, and hypersensitivity pneumonitis can all result from mold exposure.

Water- and mold-damaged homes are also expensive to repair, as mentioned previously. Their market and property values can drop, as buyers often know these problems cost a lot of money to address.

Avoid those problems and improve home longevity and property appreciation instead with these money-saving, home value-increasing strategies to prevent water intrusion.

Cleaning Gutters and Downspouts 

Keeping your gutters clean and clear can help prevent water damage and preserve your home's integrity, as noted in this guide discussing professional gutter cleaning in Charlotte, NC.

Your gutters, which connect to downspouts, are channels that divert rainwater away from your home. Let them clog up with dead foliage (fallen leaves, twigs, and branches), and they can do more than reduce your home's curb appeal by making it look untidy and not well taken care of. They can also cause rainwater to overflow out of the gutters.

Repeated overflow, over time, can damage your:

• Roof
• Fascia
• Walls
• Foundation

The more overflow there is, the more likely intrusion can occur, and the greater the amount of water that can seep into and damage your home.

Sealing Gaps Along Exterior Doors and Windows 

Stop rain and other sources of moisture from entering spaces in your building's envelope (e.g., gaps between doors, windows, and utility line penetrations) by sealing them with:

• Caulk
• Weatherstripping
• Expandable foam

Sealing these gaps and holes blocks unwanted water from entering your home. It also helps protect your home's structural materials and insulation from water damage and rotting.

Remember: Extended or repeated exposure to water can corrode steel and cause masonry joints to crumble. It can also rot wooden framing and support systems while causing insulation to become wet and lose its thermal effectiveness (R-value).

Investing in Early Detection Tools 

Early leak or moisture detection tools are small devices, usually handheld and portable, that allow you to catch potential water intrusion problems.

You can use home moisture meters, for instance, to measure how much water certain building materials may contain. Conversely, leak detectors can help you establish the presence of active drips or free-flowing water. You can use both devices to scan the following for unwanted moisture:

• Drywall
• Wood
• Concrete
• Masonry

Using these devices can help you find and address leaks, water intrusion, and other sources of unwanted water early, before they cause more extensive and more expensive problems.

Frequently Asked Questions

Is Water Intrusion the Same as Flooding? 

No, water intrusion and flooding are not the same. A flood can be a source of water intrusion, but not all cases of water intrusion are due to flooding, as it can result from roof leaks, gutter overflows, and downspout failures.

Clogged gutters and dislocated downspouts, for example, can dump water straight against your property's foundation. From there, the water can flood your basement or cause the surrounding soil to erode.

Foundation cracks can also allow rainwater to seep into your home and accumulate in its lowest levels (e.g., the basement).

What Are the Signs of "Hidden" Water Intrusion? 

Since many cases of water intrusion aren't immediately noticeable, you need to proactively "hunt" for them as part of your home maintenance tasks.

Carefully look for any peeling sections or bubbling in wallpaper or paint. Signs of discoloration or water stains (e.g., faint yellow, light brown, and sometimes dark rings) on walls and ceilings can indicate pipe leaks or water intrusion from the roof.

Use your olfactory senses, too; in many cases, water intrusion can promote mold growth, which emits earthy, musty odors.

Preserve Home Value and Save Money by Keeping Water Intrusion at Bay 

Water intrusion, particularly if repetitive and not addressed right away, can devalue your home and cost you thousands in repairs. The good news is that with routine and proactive maintenance, from cleaning gutters to sealing gaps and using detection tools, you can prevent these costly problems from occurring.
