Here are some key aspects of drainage in a home inspection:

Exterior Grading: The grading or slope of the land surrounding the home plays a crucial role in drainage. During a home inspection, inspectors evaluate the grading to ensure that the ground slopes away from the foundation, directing water away from the home. Poor grading that slopes towards the foundation can lead to water pooling around the perimeter of the house and increase the risk of basement flooding and foundation damage.

Gutters and Downspouts: Gutters and downspouts are components of the home’s exterior drainage system that collect rainwater from the roof and channel it away from the foundation. During a home inspection, inspectors check the condition and functionality of gutters and downspouts to ensure that they are free of debris, properly attached to the roofline, and directing water away from the foundation. Clogged or damaged gutters and downspouts can cause water to overflow and accumulate around the foundation, leading to water damage and structural issues.

Downspout Extensions: Downspout extensions, also known as downspout diverters or splash blocks, are installed at the end of downspouts to further direct water away from the foundation. Inspectors evaluate the length and placement of downspout extensions to ensure that they discharge water at least several feet away from the foundation to prevent soil erosion and water penetration into the basement or crawlspace.

Drainage Swales and French Drains: In properties with poor natural drainage or areas prone to water accumulation, drainage swales or French drains may be installed to redirect surface water and groundwater away from the home. During a home inspection, inspectors assess the condition and effectiveness of drainage swales and French drains to ensure that they are properly installed, free of obstructions, and functioning as intended.

Overall, proper drainage is critical for maintaining a dry and structurally sound home. During a home inspection, inspectors evaluate various components of the drainage system to identify potential issues and ensure that water is effectively managed and directed away from the property to prevent water damage and moisture-related problems.
