Landscaping & hardscape
in Antioch
Antioch yards are mostly newer, mostly flat and mostly hot. The jobs that matter here are shade, irrigation that does not waste water, and correcting the grading the builder left behind.

Why Homeowners Choose Us
Why Antioch 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.

Contact UsThings that want it. We plant for the actual climate and set irrigation up to deliver deeply and less often, which is what builds drought tolerance.
Almost always the base. Clay moves, and a slab on a thin or uncompacted base moves with it. Rebuilt properly it stays flat.
Yes — pergolas, structures and planting for shade are a large part of what makes an East County yard usable in summer.
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 city before designing.
Depends on scope and earthwork. Written schedule with the written price.
Serving Antioch
Thirty minutes east
We run out of Concord along the 4. Far enough that we plan the day around the drive; close enough that site visits happen the same week.
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
Antioch lots have enough in common to plan for, and planning for it is most of the job.
Heat sets the plant list
Summers here are genuinely hot, and a planting plan that ignores that fails in its first August. We choose for the climate and design the irrigation to suit, rather than the other way round.
Expansive soil, newer slabs
New does not mean stable. The clay still swells and shrinks, and patios poured on a thin base crack within a few seasons. Deeper excavation and a proper base are what prevent it.
Builder grading is a starting point
Production grading moves water far enough to pass inspection, not far enough to keep it away from your foundation for twenty years. Correcting it is usually straightforward and always cheaper than the alternative.

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.
