Find the source, then fix it
Every drainage problem has a source: roof water, runoff from a slope, compacted soil, a high water table or grading that slopes toward the house. We diagnose where the water is coming from and where it needs to go, then design a system that moves it away safely.
Keep the system working
Drains and catch basins collect leaves and sediment. Our residential maintenance program includes drainage cleaning to prevent clogging and flooding, especially before and during the rainy season.
What to Expect When You Work With Us
- Consultation: we walk the property with you, listen to your goals and assess slopes, drainage, sun and existing trees.
- Design: our designer develops a plan for layout, hardscape, planting, irrigation, drainage and lighting.
- Construction: our in-house crew builds the project, and your designer stays involved through completion.
- Ongoing care: our residential maintenance program keeps the landscape performing, with irrigation and lighting audits three times a year.
Because we handle design and construction in-house, drainage solutions can be planned together with the rest of your landscape, including grading, drainage, irrigation and lighting, so everything is installed once and installed correctly. Since 1972, Del Conte’s M&H has focused on high-end residential work, and our long-time managers bring decades of experience to every project.

As a full-service landscape construction company, we can also combine this work with the rest of your landscape, so every element is planned and built together.
