Landscaping & hardscape
in Diablo
Diablo is old, wooded and narrow-laned, and all three shape the work. Big parcels under heavy canopy, access that has to be planned, and a character worth not damaging.

Why Homeowners Choose Us
Why Diablo homeowners
hire DMG
Hiring a contractor is mostly a question of whether the person quoting is the person who turns up. Here is what you get with us.
One in-house crew
The same faces from the first walkthrough to the final clean-up. No subcontractors, ever — so nobody shows up not knowing what was agreed.
The price in writing first
A detailed written proposal before anyone breaks ground, and a fixed price we hold to. No surprise change orders halfway through.
Built for Contra Costa clay
Deeper excavation, a compacted base that absorbs seasonal movement, and joints placed where the slab wants to crack. The reason our work is still flat years later.
Design and build together
One company draws it and one company builds it. Nothing gets lost in the handoff between a designer and whoever ends up holding the shovel.
A reply within 24 hours
Every enquiry answered within one business day, and a direct line to the person actually running your project once it starts.
Licensed and insured
Fully licensed and insured, with references a few streets away. Ask and we will point you at work you can go and look at.

Questions about working
in Diablo
Have a question we haven’t answered? Call or send a message — we respond within 24 hours.
Contact UsThat is the first thing we check, and on these lanes it is a genuine question. Gate widths, overhead clearance and where a truck can park, all at the free site visit.
Less than people hope, and choosing for shade and root competition rather than for the picture is the difference between a planting that establishes and one that limps. We will tell you which is which.
Generally depends on height. California’s building code exempts walls up to four feet from the bottom of the footing to the top; above that a permit is normally required. We confirm with the county before designing.
Not if it is planned around them. Where a design and a tree conflict, the design changes.
Access usually sets the pace here. We will not quote a timeline before walking it; written schedule with the written price.
Serving Diablo
Twenty-five minutes, and carefully
We run out of Concord. Diablo is a short run but a slow last mile — narrow lanes and mature trees mean the approach matters as much as the drive.
We are a design-and-build outfit, so one company handles the drawing, the earthwork, the hardscape and the planting. Every service below is ours — none of it is handed to a subcontractor once you have signed.
What We Run Into Here
What we run into
on these properties
Diablo lots have enough in common to plan for, and planning for it is most of the job.
The lanes decide the method
Narrow roads and low branches mean large equipment often cannot reach the back of a parcel. We establish that at the walkthrough, because it changes the method, the schedule and the price.
Canopy you work beneath
Heavy mature cover constrains excavation and changes what will actually grow underneath. Planting plans that ignore shade and root competition fail quietly over two seasons.
Old properties hide things
Irrigation, drainage and utilities on a property this age are rarely where a plan says. We locate before we dig rather than find out with a machine.

We cover most of
Contra Costa County
We run out of Concord, which puts nearly every town on this map inside a half-hour drive. That is the difference between a contractor who can walk your property this week and one who fits you in next month.
Not sure whether you are in range? Call and ask — and if we are not the right fit, we will usually know someone who is.
