Custom Build Hardscaping, Patios, and Retaining Walls

Where Engineering Meets Outdoor Living.

Hardscaping is more than looks, it’s about creating outdoor spaces that stay functional and stable for decades. Poor installation leads to shifting pavers, leaning walls, and wasted investment. Our approach focuses on the right materials, precise excavation, and proven installation methods that hold up against Maryland’s clay soils, freeze/thaw cycles, and heavy rains.

If your project calls for excavation, grading, or hardscaping, our crew has the tools and experience to handle it. Every hardscape project comes with a 5-year warranty, and larger patio or retaining wall builds may qualify for financing through Acorn Finance.

Hardscape Materials Built for Strength & Reliability

We exclusively use Nicolock pavers and wall products because of their consistency, durability, and contractor support. Every project is finished with polymeric sand or resin joints, which resist erosion, weeds, and shifting over time.

Unlike outdated methods that use stone dust or plain sand, our approach ensures your patio or wall holds up against Maryland’s wet climate and freeze/thaw cycles.

Whether it’s a backyard patio for entertaining, a winding garden walkway, or a decorative seating wall around a fire pit, the materials we use are chosen to keep your investment looking sharp for years.

Our Proven Paver Patio Installation Process

A patio is only as strong as its base. We excavate a minimum of 8 inches for patios (10 inches for driveways), removing all soft or organic material to ensure proper compaction. The base is built with layers of clean, compacted stone — not crusher run or sand — followed by a bedding layer that locks the pavers in place. Edges are reinforced with concrete, and joints are sealed with polymeric sand or resin.

This method creates a patio or driveway that stays level and secure, whether you’re building an outdoor dining space, a poolside lounge area, or a wide driveway that can handle daily traffic without ruts.

Many contractors still use outdated sand or crusher run bases, which are prone to washouts and settling. Our system uses clean stone layers and modern joint stabilization, ensuring your patio remains level and secure for decades.

Permeable Pavers & Driveways for Stormwater Control

What are permeable pavers?

Permeable pavers and concrete are designed to let water flow through the surface, reducing runoff and helping properties meet stormwater regulations. They’re especially useful in Maryland where zoning restrictions limit impermeable surfaces.

These systems are perfect for driveways that won’t puddle, patios that stay dry after summer storms, or pathways through gardens that don’t turn muddy. Permeable hardscapes look just as polished as traditional installations while handling water efficiently.

Yes, absolutely. They help prevent pooling and runoff by letting water soak into the ground below. They’re also a great option if you need to stay compliant with stormwater or zoning codes.

Hardscape Warranty, Quality Assurance & Financing

All of our hardscape and drainage projects are backed by a 5-year warranty. We don’t just build patios and walls that meet code, we make sure they’re finished to look complete and blend with the property. That means walkways that connect seamlessly to entrances, fire pits surrounded by safe seating areas, or retaining walls that stabilize slopes while adding curb appeal.

Beyond performance, we take pride in restoring disturbed areas as close as possible to their original condition so your property looks polished when we leave.

For larger projects, we also partner with Acorn Finance to offer flexible loan options for hardscaping work. This makes it easier to bring big ideas — like a full backyard patio redesign or a Redi-Rock retaining wall system — within reach.
