Paver Patios, Walkways & Retaining Walls in New Castle County
Union Park Landscaping builds paver patios, walkways, fire pits, and retaining walls across Wilmington and New Castle County. The difference between a patio that lasts 30 years and one that heaves in 3 is invisible when the job is finished — it's the excavation depth, base material, and compaction underneath. We build the base right, every time.
From a simple front walkway to a full outdoor living space with seating walls and a fire pit, we design hardscapes that fit your home's style and your budget, and we quote them in writing before a shovel hits the ground.
Homeowners call us for hardscaping when…
- The concrete patio is cracked, stained, or sinking
- There's no defined outdoor space for grilling and gathering
- A sloped section of yard is eroding and needs a retaining wall
- The front entry path is a muddy shortcut through the lawn
- They want a fire pit area to use the yard past summer
How we work
- Design & layout. We measure, discuss materials (pavers, natural stone, wall block), and mark the layout so you can see the footprint before you commit.
- Excavate & build the base. We excavate to proper depth, install geotextile where soil requires it, and compact stone base in lifts — the step cheap installers skip.
- Set, cut & finish. Pavers are set to consistent slope for drainage, cuts are clean, joints get polymeric sand, and we haul away all debris.
Built for Delaware conditions
New Castle County's clay-heavy soil holds water and moves with freeze-thaw cycles, which is why patios built on shallow bases fail here. We excavate deeper and compact more than the minimum, and we pitch every surface away from your foundation — a detail that matters on Delaware's older Wilmington lots where grading is tight.

Typical paver patios in New Castle County run $5,000–$18,000 depending on size, material, and site access. Walkways often start around $2,500. Free written estimates with material options at multiple price points.
Hardscaping questions, answered
How much does a paver patio cost in Delaware?
Most paver patios in New Castle County cost $25–$40 per square foot installed, so a 400 sq ft patio typically runs $10,000–$16,000. Size, paver choice, site access, and features like seating walls or fire pits move the number.
Pavers or concrete — which is better?
Pavers cost more upfront but resist cracking, can be repaired seam by seam, and handle Delaware's freeze-thaw cycles far better than poured concrete slabs. Concrete is cheaper initially but cracks are permanent.
How long does a patio installation take?
Most residential patios take 3–7 working days once we start, depending on size and weather. We give you a schedule with your estimate.
Do I need a permit for a patio or retaining wall in New Castle County?
Ground-level patios usually don't require a permit, but retaining walls over 4 feet and structures may. We'll tell you exactly what applies to your project during the estimate.
