Introduction

Hello and welcome to the Hardscape page at Classic Landscaping + Nursery! As your family-owned partner for residential landscape design, installation, and maintenance on Seattle’s East Side and North Seattle, we’ve been crafting beautiful, functional yards for over 40 years. Hardscape refers to the non-living, built features of your landscape—like patios, paths, and walls—that provide structure, usability, and longevity. In Seattle’s maritime climate, with heavy winter rainfall (about 37 inches annually), mild temperatures, and often clay-heavy soils prone to erosion, hardscape is essential for managing water flow, preventing slips on wet surfaces, and creating level, enjoyable spaces. These elements form the “bones” of your garden, supporting softscape like plants while withstanding our region’s wind, moisture, and occasional freezes.

At Classic Landscaping + Nursery, we emphasize traditional, proven hardscape materials and techniques that offer reliability and timeless appeal for everyday or formal landscapes. These include classic pavers, concrete, and stone that are durable and easy to maintain, making them ideal for high-traffic areas or sloped properties. That said, we also offer alternatives like permeable surfaces for those seeking options that aid drainage. With countless materials and designs available, the suggestions below are just a place to start—each property has its own topography, drainage needs, and aesthetic goals. That’s why working with our team of experienced landscape designers is invaluable; they’ll help you navigate the intricacies of selecting and installing hardscape features appropriate for your specific yard, ensuring safety, beauty, and value. All our recommendations are grounded in established landscaping practices from sources like the American Society of Landscape Architects (ASLA) and local building codes—because precision in hardscape is what sets us apart. Let’s build something enduring!

Patios and Decks: Suggestions for Outdoor Living Spaces

Patios and decks extend your home’s living area, providing stable surfaces for entertaining or relaxation. In Seattle, where rain can make grass muddy, these hardscapes create dry, usable zones year-round. Traditional materials like concrete or wood offer classic durability, but with thousands of options, these are starting suggestions. Our designers can assess your property’s slope, sun exposure, and usage to recommend the best fit, avoiding common pitfalls like poor drainage or material warping.

Suggested Patio and Deck Materials

  • Concrete Patios: Consider stamped or poured concrete for a versatile base, customizable with patterns mimicking stone or brick. It’s a good starting point for level yards, holding up to Seattle’s wet conditions without cracking if properly installed. Pros: Affordable and low-maintenance; can be colored or textured for aesthetics. Cons: Can absorb heat in summer; requires sealing to prevent stains from rain. Care Tips: Install with a slight slope (1/4 inch per foot) for drainage; seal annually with a penetrating sealer. Clean with mild soap and water; repair cracks promptly with epoxy fillers. Our team can integrate it with surrounding softscape for seamless flow.
