Why this decision trips people up
Most homeowners planning an outdoor project start by getting quotes. The problem is they often get quotes from two different kinds of professionals without realizing it. A landscaper and a general contractor can both build you a patio, but they think about the project differently, price it differently, and hand off different results. Picking the wrong one does not usually ruin the project. It just means paying for expertise you did not need, or missing expertise you did.
What each one is actually trained to do
A general contractor’s background is structural. They know framing, foundations, permits, and how to manage trades like electricians and plumbers. If your project involves a permanent roof structure, a change to your home’s exterior wall, or plumbing for an outdoor kitchen sink, a contractor’s experience with code and inspection is hard to substitute.
A landscaper’s background is the ground plane and everything living on it. Grading, drainage, soil, planting, and how materials like stone or wood perform outdoors over years, not just on installation day. Their expertise shows up in details a contractor might not think to ask about: how water moves across a slope after a heavy rain, which plants will actually survive next to a south-facing wall, or how a deck’s footings interact with root systems nearby.
Match the project to the skill set
Some projects clearly favor one side:
- A pergola attached to your house, or a screened structure with a roof: contractor territory.
- A garden redesign, planting plan, or drainage fix: landscaper territory.
- A rooftop terrace: this one is worth pausing on, because it usually needs both.
Rooftop and terrace projects blend structural concerns (weight loads, waterproofing membranes, railing codes) with landscape concerns (planters, irrigation, wind-tolerant plants). This is where a lot of homeowners get surprised by scope. A contractor might handle the structural side well and then default to generic planters and mulch, because plant selection was never their focus. A landscaper might design a beautiful planting scheme and then need to bring in a contractor anyway for the structural sign-off.
Questions that reveal who you are actually talking to
Before you commit to either, ask a few direct questions:
Who pulls the permit, and who is named on it? This tells you who is legally responsible for code compliance.
Have you built this specific type of project before, or something adjacent to it? A deck builder and a retaining wall specialist are not interchangeable, even within the same trade.
Who do you subcontract, and do I get to meet them? Both landscapers and contractors often bring in specialists. You want to know who is actually doing the work on your property.
What happens to the plants and soil after year one? This question separates people who think about installation from people who think about long-term maintenance. A generic answer here is a signal to keep looking.
When to hire both, and how to sequence it
For larger projects, many homeowners end up hiring both a contractor and a landscaper, just not at the same time. The usual order is structural work first: decks, retaining walls, drainage pipe, any electrical or plumbing rough-in. Planting and finish grading come last, because construction traffic and material staging will damage new plants if they go in too early.
If you are managing this yourself rather than through a single design-build firm, get the sequencing in writing before either crew starts. Nothing causes more rework than a contractor’s equipment crushing a landscaper’s freshly graded soil, or a planting bed going in before an irrigation line is trenched underneath it.
A note on hybrid firms
Some outdoor design companies now combine both skill sets under one roof, which removes the handoff problem entirely. Frank Saltarelli, founder of Saltarelli Outdoor Design in Montreal, is one example of a landscape designer whose work spans planting design through to the structural elements of terraces and outdoor living spaces. Firms like this are worth asking about directly: not every landscaping company actually carries structural expertise in-house, even when their marketing suggests otherwise.
The simplest test
If you are still unsure which professional fits your project, describe it in one sentence and notice which word does more work: the structure, or what grows around it. That word usually points to the right first call. For anything in between, ask both types of professional to walk your site before you sign anything. Their questions will tell you more about their expertise than their portfolio will.
