We design and install irrigation systems tailored to your yard’s soil, slope, sun exposure, and Sammamish’s seasons. Smart controls, targeted watering, seasonal startup, and winterization help manage moisture and reduce water waste.

We install paver patios and walkways in concrete, brick, or natural stone, with compacted bases, drainage slopes, and polymeric sand joints. Patterns and colors complement your home’s exterior and existing landscaping.
Landscape Lighting
We install low-voltage LED landscape lighting for walkways, entryways, and outdoor living areas. Custom layouts combine pathway lights, uplighting, and downlighting, with timers or smart controls available for automatic operation.
Meet the Owner: Brian Lesky
Originally from western Washington, Brian got his start helping a neighbor with yard cleanups and planting projects. He enjoyed figuring out why parts of a yard strugled, whether it was a soggy lawn or a garden bed that never thrived. That curiosity eventually led him to start Sammamish Quality Landscaping.
Brian settled in Sammamish with his wife because they liked the wooded neighborhoods and nearby trails. Through the business, he takes a practical approach to helping homeowners enjoy their yards. He likes walking a property with the owner to understand their frustrations, then talking through what could work better. He gives grading and soil preparation just as much attention as the finished landscape.
Outside of work, Brian enjoys hiking with his wife and their Labrador, usually choosing a trail with somewhere to stop for lunch. He also keeps a vegetable garden, where he admits the zucchini does better than anything else. On quieter weekneds, he cooks breakfast for the family and tackles small projects around the house.

Frequently Asked Questions
Project duration depends on scope and complexity. A simple garden bed or small planting area typically takes one to two weeks from design to completion.
Larger projects involving hardscaping, irrigation, or extensive grading can take two to four months. Weather conditions in the Pacific Northwest also play a role, since heavy rain can delay excavation and concrete work.
We provide a realistic timeline estimate after assessing your property, so you know what to expect before work begins. Most residential projects in Sammamish fall somewhere between these extremes, depending on material availability and the number of features included in the design.
We structure every project around clear milestones so you can track progress from start to finish.
Phase Typical Duration
Site assessment 1-2 days
Design & planning 1-3 weeks
Material procurement 1-2 weeks
Installation 2 days - 3 months
Final walkthrough 1 day
These timeframes shift based on project size and permit requirements. For projects requiring permits through King County, we factor in additional review time, which can extend the overall schedule by several weeks.
We keep you informed at each milestone so there are no surprises about progress or completion dates.
Before any design work starts, we conduct a thorough inspection of your property. This includes evaluating soil composition, drainage patterns, existing vegetation, and sun exposure throughout the day.
We also check for underground utilities and note any slope or grading issues common in Sammamish properties. This step typically takes one to two days, depending on lot size and terrain complexity.
The findings from this assessment directly inform what materials and plant species will perform well on your site. Skipping this step often leads to problems later, such as poor drainage or plants that fail to thrive in local soil conditions.
Once the assessment is complete, we move into the design phase. This involves creating a layout that matches your property's conditions and your stated preferences for function and appearance.
We select materials based on durability, climate suitability, and budget. Common choices for this region include:
- Pavers for patios and walkways
- Native plants suited to Pacific Northwest rainfall patterns
- Permeable surfaces to manage runoff on sloped lots
- Irrigation systems designed for seasonal water needs
Design and planning usually takes one to three weeks, depending on how many revisions are needed. We finalize material orders and confirm the installation schedule before any ground is broken.
Landscaping projects in Sammamish typically range from a few hundred dollars for basic maintenance to over $13,000 for full-scale installations. Smaller jobs, such as mulching or seasonal cleanup, often fall between $100 and $500.
Mid-range projects, including sod installation or garden bed construction, generally cost $1,000 to $5,000. Larger projects like hardscaping, retaining walls, or complete yard renovations can exceed $10,000.
Project Type Estimated Cost Range
Lawn seeding or sod $500 – $2,500
Tree pruning $200 – $1,000
Garden design & planting $1,000 – $4,000
Full yard renovation $5,000 – $13,920
We provide itemized quotes so you know exactly what you're paying for before work begins.
Several factors shape the final price of a landscaping project. Yard size is the most obvious one; larger properties require more materials, labor, and time.
Soil conditions matter too. Sammamish has a lot of clay-heavy soil, which can slow down excavation and sod removal, affecting labor costs.
Other factors include:
- Material selection (native plants vs. specialty species)
- Accessibility of the work area
- Seasonal demand for landscaping services
- Design complexity, such as multi-tiered gardens or irrigation systems
- Permit requirements for certain structural additions
We assess each of these elements during our initial consultation to give you an accurate estimate.
