Backyard Slope Toward House: A Comprehensive Guide

A properly sloped backyard is essential for protecting your home’s foundation, preventing water damage, and preserving your landscaping. However, many homeowners may not be aware of the potential issues caused by a slope that directs water towards the house. In this comprehensive guide, we will cover everything you need to know about backyard slope issues, how to identify them, and what you can do to correct them.

Understanding the basics of grading and drainage

Before diving into the solutions, it’s important to understand the basics of grading and drainage, as they are closely related to the problem of a backyard slope toward the house.

Definitions and explanations

  • Grading: The process of leveling or sloping the ground to ensure proper water runoff away from your home.
  • Drainage: The system that collects and directs excess water away from your property, preventing damage and flooding.

Importance of proper grading and drainage

  • Home foundation protection: Proper grading and drainage help to keep water away from your home’s foundation, preventing costly repairs and structural issues.
  • Prevention of water damage and flooding: When water is directed away from your home, it reduces the risk of water damage, flooding, and mold growth.
  • Landscaping preservation: A well-drained yard helps to maintain the health and beauty of your landscaping, preventing soil erosion and plant damage.
  • Soil erosion control: Proper grading and drainage can prevent soil erosion and loss of topsoil, which can be expensive to replace.

Identifying signs of a problematic backyard slope

If your backyard slopes towards your house, you may notice a variety of signs that indicate potential issues. These can be both visible and indirect signs.

Visible signs

  • Pooling or ponding water: When water collects in low-lying areas of your yard, it can lead to soggy ground, drowning plants, and mosquito breeding grounds.
  • Soil erosion: Erosion can occur when water flows over the ground, washing away topsoil and leaving behind gullies or bare patches.
  • Cracks in the foundation: When water pools near your home’s foundation, it can cause pressure and damage, leading to cracks and other structural issues.
  • Dampness in the basement or crawl space: Excess water near your home can seep into basements or crawl spaces, causing dampness and musty odors.

Indirect signs

  • Mold and mildew growth: Moisture from poor drainage can lead to mold and mildew growth in your home, which can cause health issues for your family.
  • Unpleasant odors: Dampness and mold growth can result in unpleasant, musty odors in your home.
  • Pest issues: Standing water and damp conditions can attract insects, rodents, and other pests to your property.

Methods for correcting backyard slope issues

There are several methods to correct a backyard slope that directs water towards your house. These include re-grading, installing drainage systems, and combining landscaping solutions with drainage.


Re-grading is the process of altering the slope of your yard to direct water away from your home. Here’s how to approach re-grading:

  1. Assessing the current slope: Use a level to determine the slope of your yard and identify problem areas.
  2. Calculating the required slope: Generally, a slope of 2% (1/4 inch per foot) away from the house is recommended for proper drainage.
  3. Steps for re-grading: Excavate soil from high areas and redistribute it to low areas, creating a new slope that directs water away from your home. Compact the soil and add topsoil as needed. Finish by seeding or sodding the area to establish vegetation and prevent erosion.

Installing drainage systems

If re-grading alone is not sufficient to solve your backyard slope issues, you may need to install a drainage system. There are several options to choose from:

  1. French drains: A French drain is a trench filled with gravel or rock that contains a perforated pipe. Water seeps into the trench, enters the pipe, and is diverted away from your home.
  2. Dry wells: These are underground structures that collect and store excess water, allowing it to slowly infiltrate into the ground.
  3. Swales: Shallow, sloped channels lined with grass or vegetation, swales help direct water away from your home and slow its flow, reducing erosion.
  4. Catch basins and drain pipes: Catch basins collect water from gutters and downspouts and connect to underground drain pipes, which direct water away from your home.

Combining landscaping solutions with drainage

Incorporating landscaping features can help enhance the appearance of your yard while also improving drainage:

  1. Creating berms or terraces: These raised areas can help redirect water flow and reduce erosion on sloped properties.
  2. Rain gardens: Shallow depressions filled with native plants, rain gardens help slow down water runoff and encourage infiltration into the ground.
  3. Permeable pavers: Installing permeable pavers for patios or walkways allows water to pass through the surface, reducing runoff and improving drainage.

Hiring a professional vs. DIY

Depending on your skills and capabilities, you may choose to tackle backyard slope issues yourself or hire a professional. Consider the following when making your decision:

Assessing your skills and capabilities

Evaluate your experience with landscaping and drainage projects, as well as your access to the necessary tools and equipment.

Cost comparisons

Compare the costs of DIY materials and equipment rentals to the price of hiring a professional.

Benefits of hiring a professional

  • Expertise and experience: Professionals have the knowledge and experience to accurately assess and address backyard slope issues.
  • Proper equipment and tools: Professionals have access to the necessary equipment and tools to complete the job efficiently and effectively.
  • Warranty and insurance: Hiring a professional often comes with a warranty on workmanship and insurance coverage for any potential damages.

Tips for choosing the right contractor

  1. Research and referrals: Ask friends, family, and neighbors for recommendations, and research online reviews.
  2. Licensing and insurance verification: Ensure the contractor is licensed and insured to work in your area.
  3. Requesting multiple quotes: Obtain quotes from several contractors to compare pricing and services.
  4. Checking reviews and testimonials: Look for customer reviews and testimonials to evaluate the contractor’s reputation and quality of work.

Maintenance and prevention

To keep your backyard slope issues under control, regular maintenance and prevention measures are essential:

  • Regular inspections: Inspect your yard for signs of erosion, pooling water, or other drainage issues regularly.
  • Gutter and downspout maintenance: Clean your gutters and downspouts regularly to prevent blockages and ensure proper water flow.
  • Vegetation and landscape management: Maintain your landscaping by trimming overgrown plants, removing dead vegetation, and addressing any potential erosion issues.
  • Addressing small issues before they escalate: Take action to correct small drainage or slope problems before they become larger, more costly issues.


Addressing backyard slope issues is essential to protect your home’s foundation, prevent water damage, and preserve your landscaping.
