How Long Does a Landscaping Project Take in Boulder County?

Design, start date, and installation each run on their own clock. Here is what Green Landscape Solutions publishes for homeowners in Niwot and across Boulder County, and what moves the schedule.

Quick Summary

  • Green Landscape Solutions publishes three timing ranges: design usually takes 2 to 4 weeks, work typically begins within 2 to 8 weeks of contract acceptance, and installation can run 2 to 8 weeks.
  • Scope, weather, and the time of year affect those numbers.
  • Utility locates need at least 3 business days of notice before anyone digs.
  • Boulder's average first frost lands in early October, so late-season starts may wait for spring.
  • You get a detailed timeline for your own property during the consultation.

How long does a landscaping project take in Boulder County?

Green Landscape Solutions says design typically takes 2 to 4 weeks, and installation can range from 2 to 8 weeks. Work typically begins within two to eight weeks of contract acceptance, depending on weather and the time of year. Your own timeline depends on scope and complexity.

Those figures come from the firm's design-build page. They are ranges, not promises. A small planting bed and a full backyard rebuild with a patio, lighting, and irrigation sit at opposite ends of them.

One thing to watch: the start window and the installation window are separate ranges. The firm does not publish a single total, and the ranges can stack. Ask for dates in writing before you sign.

Three stages: design 2 to 4 weeks, work starts in 2 to 8 weeks, installation 2 to 8 weeks

What are the stages from first call to final walkthrough?

Green's process has five steps: initial contact, consultation, design and budget, build, and a final walkthrough. The clock starts moving at different points in each step, and some of them depend on you.

1. Initial contact and consultation

The team collects your ideas and contact details, then schedules a consultation to talk through services. This is where you ask for a timeline. The firm says it provides a detailed one during the consultation.

2. Design and budget

You approve a design proposal and return it signed with a retainer. The retainer is what begins the design process. The published design range is 2 to 4 weeks.

You control part of this stage. Slow decisions on materials or layout add days. Quick, clear feedback on the first draft helps keep design moving.

3. Build

After you approve the design, you receive an installation proposal. When Green receives the signed contract and deposit, the team schedules the job and orders materials. Scheduling and material ordering happen at this point, so work does not start the next morning.

4. Final walkthrough

You and the designer or project manager walk the finished landscape. Anything that needs attention is noted and, in the firm's words, promptly resolved.

What makes a project take longer?

Several things can stretch a schedule: project size, weather, the time of year, and what is buried under the work area. The first three come from Green's published language. The fourth is a notice requirement that applies before digging.

Scope and complexity

The firm states that timelines vary with scope and complexity. A project that combines hardscape, planting, and irrigation has more steps to sequence than a single feature. Each step has to finish before the next one can start.

Weather and season

Green ties its start window to weather and time of year. Outdoor work in Colorado has a real season, and fall pushes against it. NOAA's Boulder record puts the average first frost on October 6, using data from 1948 to the present. NOAA defines frost there as a minimum temperature at or below 32 degrees F.

That is an average, not a forecast. It does show why a contract signed in late October may land on a spring calendar.

Utility locates

Before anyone digs, utilities have to mark buried lines. The City of Longmont tells residents to make a locate request with the Utility Notification Center of Colorado, also called Colorado 811, at least 3 business days before work starts. You can call 8-1-1 or 800-922-1987.

Plan for that notice window. It matters on any job that moves soil.

Does fall or winter work for a landscape project near Niwot?

It depends on the work. Some jobs can proceed in cool weather and others are better held for spring. For Niwot, Longmont, and the rest of the Boulder County service area, ask Green which parts of your scope suit the season.

Planting is a useful example. Colorado State University Extension says balled-and-burlapped nursery stock is best transplanted in cooler weather, generally spring or fall. Container-grown trees can go in during spring, summer, or fall. Bare-root trees are generally only available in early spring, before leaf-out, and survival drops rapidly once the plant leafs out.

That guidance covers tree planting only. It does not tell you how a patio or wall will schedule. For those, Green's weather and time-of-year language applies.

Winter is also a planning season. Design takes 2 to 4 weeks, so a signed design proposal in winter can have you ready when the build window opens. Green's earlier post on why winter is the best time to plan for spring covers that idea in more detail.

How do you keep your project on schedule?

You cannot control the weather. You can control the parts that sit on your side of the table. These habits help the design stage and protect the build date.

  • Decide your priorities before the consultation. Know what you want to use the space for. Sort the must-haves from the nice-to-haves.
  • Return signed paperwork promptly. The retainer starts design. The signed contract and deposit start scheduling and material ordering.
  • Keep one team accountable. Green is a design-build firm, so the same company designs and builds. Fewer handoffs means fewer places for delays to hide. Our post on design-build versus hiring separately explains the difference.
  • Ask for dates, not just durations. Request an estimated start and finish window in writing.
  • Make decisions on materials early. Green orders materials once the contract and deposit arrive, so late changes can ripple forward.

Financing is available through HFS Financial. Details are on the financing page.

Frequently Asked Questions

Colorado 811 asks that locate requests be made at least 3 business days before digging. Ask your contractor who handles the request on your job, and confirm it is done before work begins.

Can I start a project in the fall?

Some work can proceed in cool weather, and CSU Extension notes that spring or fall suits balled-and-burlapped trees. Whether your full scope fits the season is a question for your consultation.
