Two proposals for the same backyard arrive eleven thousand dollars apart, and nothing on either page explains why. That gap is the most common problem homeowners hit when comparing landscape design services in Owings, MD, and it rarely comes down to the pavers.
McKenzie Contracting holds a Maryland Home Improvement License, a Maryland Tree Expert License, a Maryland Marine Contractor License and Chesapeake Bay Landscape Professional certification. That range matters here, because the difference between two numbers usually sits in the work that happens before anything visible gets installed.
A proposal that lists a finished square footage and a material describes an outcome, while a proposal that lists excavation, base depth, drainage and grading describes a job.

What Should a Landscape Design-Build Proposal Actually List?
A landscape design-build proposal should list each phase of the work as its own line item rather than one lump sum. Ours starts with a first call to Gene and an on-site review with a sales representative, who walks the property and looks at grading, access, drainage and any permitting or engineering needs.
The proposal that follows separates excavation, base material and depth, drainage, the hardscape itself, planting and cleanup. Each of those is a place where two companies make different decisions.
A single combined figure hides every one of them, so a homeowner reading two lump sums is comparing confidence, not scope.
Why Does Patio Base Depth Change a Landscape Proposal’s Price?
Base depth changes the price because it changes the volume of material, machine time and haul-away on the job. A patio built on four inches of compacted stone and a patio built on eight carry different material costs, different equipment hours and different disposal loads.
The two patios also behave differently in their fifth winter. The surface looks identical on handover day, which is exactly why the number belongs on the page rather than in the installer’s head.
Clay-heavy soils hold water across much of Southern Maryland, so the base does more work here than the same detail would in sandier ground.

How Much of a Landscape Budget Goes Underground?
On a sloped Southern Maryland lot, a large share of the budget goes into work nobody sees once the project is done. Grading, drainage, retaining walls and base preparation all come before the finished space, and on a difficult site they can account for more than the surface itself.
A patio only performs as well as what sits beneath it. We plan the slope, compaction and drainage so water moves away from the house rather than toward it, and that planning shows up as priced line items instead of assumptions.
When one proposal looks far cheaper than another, this underground scope is usually where the difference lives.
What Does a Chesapeake Bay Lot Add to a Landscape Design Scope?
A Chesapeake Bay lot adds water handling to the scope, and that work is a design discipline of its own. Northern Calvert County properties drain toward the Bay, so how a site sheds stormwater matters beyond the property line.
Our Chesapeake Bay Landscape Professional certification reflects that responsibility. Swales, outlets, grading and the route water takes off a property are design decisions, and they get drawn into the plan rather than improvised on the day.
A proposal that treats runoff as an afterthought on a Bay-adjacent lot is a proposal with a gap in it.
Which Questions Separate Two Similar Landscape Quotes?
Four questions separate two similar landscape quotes: who does the excavation, what base depth is specified and why, where the water goes, and what happens to the price if the grade turns out differently once the ground is open. It also pays to ask which parts of the job are subcontracted.
Our design-build work and the site work behind it run through in-house crews, which answers that last question.
A project manager stays with the job once it is scheduled and sends daily updates on builds that run longer than a day. Those details rarely appear on a proposal, so asking about them directly is the only way to compare them.
Compare Owings Landscape Proposals Before Spring
Winter is when next season’s projects get scoped, and a proposal read carefully in December costs far less than a change order read in May.
If an outdoor space is going in on your Owings property next year, the useful next step is a site visit that produces a line-item number rather than a range.

In Summary
How far ahead of a spring installation should the site visit happen?
The site visit should happen in the autumn or early winter before a spring installation. Scoping, permits, engineering and scheduling all take time, and projects scoped early reach the installation calendar ahead of those scoped in March.
Can a landscape design-build project be completed in phases?
McKenzie Contracting outlines a phased approach upfront when a project benefits from being built in stages. Grading, drainage and base work in the first phase get planned around the finished design, so later phases connect without reworking earlier ones.
What happens if the ground turns out differently once excavation starts?
Unexpected soil, rock or water conditions affect the excavation and base line items first. A line-item proposal makes that conversation concrete, because those items are already priced separately rather than buried inside one total.
What should a homeowner have ready for the first call?
Have a rough sense of the project, the main problem on the property and the result you want from the space. Photos of standing water or slope issues help, and the on-site review covers grading, access, drainage and permitting in person.
