Drainage may not be something we spend much time thinking about, but it is no less important for protecting homes. Like HVAC systems, windows, siding, and roofs, the drainage system is meant to protect the home, keeping it safe and comfortable. In fact, proper drainage is the key to keeping our homes safe from flooding, mold, pest infestations, and foundation damage, among many other issues. Drainage problems are not only stressful, but they can be expensive, especially when undiagnosed.
Did you know that even an inch of water in a home can cause more than $20,000 in damage? Costing insurers approximately $13 billion every year (according to industry reports), water damage is nothing to take lightly. More common than many homeowners realize, drainage problems are a leading cause of insurance claims in the U.S. every year. From soil erosion to foundation issues, basement flooding to mold growth, these problems are often directly linked to poor drainage.
Drainage problems are challenging. Developing slowly over time and mostly out of sight, poor drainage can cause extensive damage before the problem is even recognized. One might not think much of a small puddle near the home’s foundation, but repeated exposure to moisture there can weaken structures, damage landscaping, and trigger mold growth, costing homeowners thousands in repairs. In this article, we will be discussing proper drainage. We will learn why it’s important, how poor drainage problems develop, and the warning signs to look out for that will help homeowners determine when to seek professional help to protect their property. Let’s get started.
Understanding Proper Drainage and Its Importance
When we hear the term “proper drainage,” we are talking about the controlled movement of water from the roof away from the home exterior, foundation, and vulnerable landscaping. A well-functioning drainage system, along with proper grading, ensures that water runoff stays at a safe distance from the home. Drainage systems consist of several key players, including gutters and downspouts, yard slope, and, for some properties, underground drainage systems or surface drains. Sump pumps are another important piece of proper drainage in homes that need them, including homes with basements, those built in low-lying areas, or those in flood zones.
If all of these systems are properly working together, water is controlled and directed away from the home, where it is discharged to a safe location. With proper drainage, our home’s structural integrity is protected, moisture-related problems are decreased, and our landscapes are preserved. To better understand how drainage goes from ”all good” to “no good”, let’s examine the common causes of poor drainage around the home.
5 Common Causes of Poor Drainage Around the Home
Poor drainage occurs for many reasons, and unfortunately, these issues are often hidden and gradual, remaining unnoticed until visible damage appears. The following are 5 of the most common factors contributing to poor drainage in homes:
Gutter Problems: Gutter problems are among the most common causes of drainage issues around a home. Whether gutters and downspouts are blocked by debris or severely damaged, they prevent water from flowing smoothly and are a problem. From the roof to the basement, failing gutters can wreak havoc on a home.
Bad Grading: The yard grade should slope away from the home’s foundation to keep water away and help it move towards a designated location. Soil that slopes towards the foundation moves water towards it, causing a range of problems depending on how long it goes undetected.
Soil Type: Location plays a major role in how well water will drain. Sitting on clay-heavy soils, homes in the Ohio River Valley around Maysville naturally drain more slowly, leading to drainage problems if the proper system is not in place.
Precipitation: Without a drainage system designed for heavy rain, areas with frequent heavy rainfall are easily overwhelmed. In areas known for heavy rainfall, proper gutter size, along with the number and placement of downspouts, becomes extremely important.
Hardscaping and Landscaping Issues: Patios, driveways, and raised flower beds can trap water and direct it towards the home if the drainage system has not been adequately planned around these areas.
These common causes of poor drainage can affect nearly every part of the home if unnoticed or unaddressed. Let’s take a moment and focus on the areas of a home that are most vulnerable to water damage when proper drainage is an issue.
Areas of the Home That Are Most Vulnerable to Damage
Poor drainage does more than form puddles or create wet spots; it can compromise entire areas of your property, both inside and out. Some problems are merely cosmetic, while others compromise the property’s integrity. Here are the areas most vulnerable to damage when poor drainage is a problem:
Foundation: The foundation is one of the most critical structural components of your home and is particularly vulnerable to water damage when drainage problems exist. When excess moisture surrounds a home’s foundation, hydrostatic pressure pushes against it, leading to cracks, shifting or settling, bowing walls, and basement leaks. Foundational problems can become extremely expensive to repair, especially if drainage issues are ignored for too long.
Basement or Crawl Space: Homes with a basement or crawl space are at increased risk of flooding and mold or mildew growth when moisture seeps in. Water damage in the basement (and crawl spaces) of a home not only causes structural damage but also poses health and safety risks.
Roof, Fascia, and Home Exterior: Poor drainage can also damage the roofline, fascia board, and the exterior walls of the home. As gutters overflow, water backs up under the shingles, saturates the fascia board, and runs uncontrolled down the exterior of the home, leading to roof rot, rotting fascia, ice dam formation in winter, and the premature deterioration of the roof.
Landscaping: Water that runs off the roofline washes away topsoil in exposed areas, damaging flowerbeds and plants, and leaving unsightly trenches across yards.
Home Interior: Long-term exposure to moisture inside the home leads to mold, mildew, musty odors, peeling paint, warped floors, stains on walls and ceilings, and weakening of structural elements, such as rot in wood framing.
Hardscaping: As water seeps under driveways, sidewalks, and patios, it gradually weakens the soil beneath these hardscape structures. Soil is weakened, and freezing during winter may result in cracked concrete, uneven walking surfaces, sunken sidewalks, and shifting pavement.
As you can see, with poor drainage, there isn’t an area of your home that is safe from the consequences. The key to preventing water damage or keeping it to a minimum, then, is knowing how to catch poor drainage before it has time to snowball.
Signs of Poor Drainage Around the Home
Because drainage issues often start slowly, homeowners should watch for early warning signs before serious damage occurs. Watch for the following telltale signs:
- Standing or pooling water near the foundation, especially if present for more than 24 hours.
- Visible water overflowing from gutters during rain.
- Muddy or soggy areas around the exterior of the home near the foundation.
- Visible cracks in the foundation, driveways, patios, or sidewalks.
- Dampness in the basement or crawl space, water stains on walls, or signs of mold and mildew growth.
- Doors and windows that “stick” shut or have gaps that let daylight through.
- Increased humidity inside the home and unexplained musty odors.
- Uneven flooring inside the home.
- Water stains and peeling paint on the walls and ceilings inside the home.
- Soil erosion around the foundation of the home.
- Increased pest activity, such as mosquito activity.
These problems may go unnoticed or seem minor at first, but they often point to a much larger drainage issue brewing.
How to Prevent Drainage Problems and When to Call a Professional
Routine care is the best way for homeowners to protect their homes against water damage. To help reduce drainage issues, homeowners can:
- Clean the gutters at least two times a year.
- Inspect the gutter system after every major storm, including the downspouts.
- Add downspout extensions to keep water away from the foundation.
- Ensure proper yard grading.
- Monitor the basement and crawlspace for moisture.
- Address small issues early.
With routine inspections, homeowners can catch drainage problems before expensive repairs become necessary. However, not all drainage issues can be corrected with maintenance. More serious problems may require professional intervention. Consider contacting Maysville rain gutter contractors if you notice:
- Persistent gutter overflow, even with routine cleaning.
- Basement leaks or flooding.
- Large cracks in the foundation.
- Extensive soil erosion.
- Ongoing mold and moisture problems.
- Water damage along the roofline, rotting fascia, or exterior damage.
Rain gutter contractors are drainage professionals who will evaluate a property, identify the source of drainage problems, and recommend the best solution for long-term home protection. Partnering with a local professional for annual inspections can greatly reduce the chances of poor drainage wreaking havoc on your property.
Protection Starts With Proper Drainage
