Why Proper Grading Around Your Home Matters in Sheridan & Johnson County, Wyoming

One of the most common issues I find during home inspections in Sheridan County and Johnson County, Wyoming—on both older homes and new construction—is improper grading around the foundation. While grading may seem like a minor detail, poor drainage is one of the leading causes of moisture intrusion, structural deterioration, and costly long-term repairs in our region.

With Wyoming’s snowmelt, spring runoff, and heavy seasonal rains, proper water management around your home is critical. When grading, siding clearances, and downspout drainage are not done correctly, water will always find its way back to the foundation.

What Is Proper Grading?

Proper grading means the soil around your home is shaped to direct water away from the foundation, not toward it. Current building standards and widely accepted construction practices recommend:

• A minimum slope of 6 inches over the first 10 feet away from the foundation (approximately a 5% slope)

• For hard surfaces such as concrete or asphalt within 10 feet of the home, a slope of at least 2% away from the structure

These slopes are designed to move rainwater and snowmelt away from the home before it can soak into the soil near the foundation.

During home inspections in Sheridan, Buffalo, and throughout Johnson County, I routinely find homes where grading is flat—or even sloping back toward the house—creating ideal conditions for water intrusion.

Proper Clearance From Grade to Siding Is Critical

Another common defect I see in Wyoming homes is insufficient clearance between exterior siding and the ground. When siding materials are installed too close to grade, moisture can wick upward and cause:

• Premature siding deterioration

• Rot in wall framing

• Increased risk of insect activity

• Moisture and mold issues in crawlspaces and basements

Many siding manufacturers require specific clearances from grade to maintain warranty coverage, yet this detail is often overlooked during construction, landscaping, or later yard modifications.

Downspout Extensions Are a Must in Our Climate

Even with proper grading, roof runoff must be directed away from the home. One of the most frequent issues I document during inspections in Sheridan County and Johnson County is missing or inadequate downspout extensions.

Downspouts that discharge water directly next to the foundation can quickly overwhelm soil, especially during spring snowmelt. Over time, this commonly leads to:

• Basement water intrusion

• Crawlspace moisture problems

• Foundation settlement

• Deteriorated siding and trim

Extending downspouts just a few feet away from the home is one of the simplest and most effective ways to reduce moisture-related issues.

Common Problems Caused by Improper Grading

When grading, clearance, and drainage issues are not addressed, I frequently see the same results during home inspections:

• Moisture intrusion in basements and crawlspaces

• Mold growth

• Rotted siding and trim

• Structural wood deterioration

• Expensive repairs that could have been prevented

Water damage often develops slowly, making these issues easy to miss until the damage is already significant.
