How to Handle Landscaping Next to Foundations and Siding

Beautiful Beds Shouldn’t Create Costly Repairs

Landscaping around the perimeter of your home adds curb appeal — but it also carries risk. Poor slope, heavy mulch, or plants placed too close can cause moisture problems, pests, and even foundation damage. Here’s how we safely landscape near foundations and siding while keeping everything clean, functional, and beautiful.

1. Start With Grading and Slope

The #1 rule: Water must flow away from your house.

We ensure:

• A minimum 2% slope for the first 5–10 feet from the foundation
  
  

• Soil or gravel pitched away from the home
  
  

• Regrading and compacting of any settled areas near the foundation
  
  

Flat or back-sloped areas can cause standing water and long-term moisture issues — especially in Colorado’s clay-heavy soils.

2. Use the Right Base Material Near the House

Best practice:

• Install a rock drip edge or gravel border 18–24" wide along the foundation
  
  

• Prevents mulch buildup and splash damage on siding
  
  

• Improves drainage and deters ants, spiders, and termites
  
  

Avoid:

• Mulch piled directly against siding or trim
  
  

• Raised beds that touch stucco or wood
  
  

• Organic materials close to entry points or vents
  
  

3. Choose the Right Plants for Foundation Zones

Good options include:

• Low-growing evergreens like juniper, boxwood, or dwarf spruce
  
  

• Drought-tolerant ornamental grasses
  
  

• Spaced perennials such as catmint, daylily, or salvia
  
  

Avoid planting:

• Deep-rooted or aggressive species like bamboo or willow
  
  

• Tall shrubs that trap moisture against siding
  
  

• Overcrowded beds that limit airflow or block window access
  
  

We design for both airflow and long-term foundation health.

4. Protect Irrigation and Utilities

Installation best practices:

• Sprinkler heads should be at least 12" from the house
  
  

• Drip lines must be routed to avoid pooling near the foundation
  
  

• All utility boxes, meters, and cleanouts must remain uncovered and accessible
  
  

We flag all utilities and irrigation lines before digging to avoid surprises.

5. Elevation, Edging & Maintenance Tips

Ongoing care recommendations:

• Keep mulch and soil 2–4" below siding
  
  

• Use aluminum or steel edging for clean, defined lines
  
  

• Check after storms for erosion or pooling
  
  

• Regrade and refresh beds every few years to maintain slope
  
  

The right edges and elevation details prevent future water damage and reduce maintenance.
