Meet the Owner: Garrett Singh

Born and raised in Cary Park, NC, Garrett got his start helping his uncle maintain rental properties during summer breaks. Bringing overgrown yards back into shape sparked an interest in landscaping that eventually led him to start his own business.

Garrett settled in Gastonia with his wife to be closer to her family. His practical approach starts with walking the yard and listening to what isn’t working. Whether reclaiming an unused corner or making a lawn easier to maintain, he focuses on everyday needs and gives preparation the same attention as the finished result.

Outside of work, Garrett enjoys fishing with his son, often stopping for breakfast afterward. He also keeps an older pickup running, joking that there’s always something to fix. On quieter weekends, he and his wife grill in the backyard while their dog keeps watch over dinner.

Frequently Asked Questions

How Long Does Landscape Design and Installation Take?

Project timelines vary with the size and complexity of the work. A simple garden bed or small planting area usually takes one to two weeks from design through completion.

Larger projects that include hardscaping or irrigation, especially those requiring extensive grading, can take two to four months. Pacific Northwest weather can also affect progress, with heavy rain sometimes delaying excavation or concrete work.

After assessing your property, we provide a realistic timeline so you know what to expect before work starts. Most residential projects in Sammamish fall between these ranges, depending on material availability and the features included in your design.

Project Timeline & Milestones

We organize each project around clear milestones, making it easy to follow progress from the initial assessment to the final walkthrough.

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

Timing varies with project size and permit requirements. If your project requires permits through King County, we allow additional time for review, which may add several weeks to the schedule.

We provide updates at each milestone and let you know if anything affects the expected completion date.

Property Inspection & Site Assessment

Before design work begins, we inspect your property to understand its soil and drainage conditions. We also review existing vegetation and how sunlight moves across the yard throughout the day.

The assessment includes checking for underground utilities and identifying slope or grading concerns on your Sammamish property. This usually takes one to two days, depending on the lot’s size and terrain.

Our findings guide the choice of materials and plants suited to your site. Taking the time upfront helps avoid drainage problems and gives new plants a better chance of establishing in your soil.

Landscape Design, Material Selection & Project Planning

After the assessment, we develop a design that suits your property and reflects how you want the space to look and function.

We choose materials that fit your budget and hold up in local conditions. Options commonly used in this region include:

  • Pavers for patios and walkways
  • Native plants suited to Pacific Northwest rainfall
  • Permeable surfaces to help manage runoff on sloped lots
  • Irrigation systems tailored to seasonal watering needs

Design and planning typically takes one to three weeks, depending on revisions. Before installation begins, we finalize material orders and confirm the work schedule.

How Much Does Landscaping Cost?

Landscaping costs in Sammamish vary with the scope of the work. Basic maintenance may cost a few hundred dollars, while full-scale installations can exceed $13,000. Smaller services, such as mulching or seasonal cleanup, often range from $100 to $500.

Mid-sized projects, including sod installation or new garden beds, generally cost $1,000 to $5,000. More extensive work involving hardscaping or retaining walls 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 before work begins, so you can see what’s included and understand where your budget is going.

What Affects Cost?

Several factors influence the final cost of a landscaping project. Larger yards generally need more materials and take longer to complete.

Soil conditions also affect pricing. Clay-heavy soil in Sammamish can make excavation and sod removal more time-consuming, increasing labor costs.

Other considerations include:

  • Your choice of materials and plants
  • How easily crews and equipment can access the work area
  • Seasonal demand for landscaping services
  • Design complexity, including tiered gardens or irrigation systems
  • Permit requirements for structural features

We review these details during the initial consultation to provide an estimate that reflects your property and the work involved.
