Decomposed granite (DG) costs $5–$10/sqft installed versus $15–$60/sqft for natural stone pavers, but natural stone is permanent, furniture-friendly, and requires virtually no maintenance after sealing. DG is ideal for large informal areas, drought-friendly gardens, and side yards where permanence is less critical. For patios, pool decks, and entertaining spaces, natural stone pavers deliver far better long-term value despite the higher upfront cost.
This guide covers cost, durability, maintenance, drainage, and the best use cases for each material in Los Angeles — from Tegula Stone's Southern California hardscape experience.
Cost is the most significant practical difference between these two materials. Decomposed granite is one of the most affordable hardscape surfaces available; natural stone pavers represent a premium investment with proportionally higher long-term value.
For a 400 sqft patio: DG costs $2,000–$4,000 installed. A flagstone patio runs $6,000–$20,000. A bluestone or granite patio runs $10,000–$30,000. The upfront gap is real — but so is the difference in longevity and property value impact.

Decomposed granite is a naturally occurring geological material — granite that has weathered and broken down into small gravel particles, typically 3/8 inch or smaller. It has been used throughout California as a low-cost, drought-tolerant surface for pathways, patios, and garden areas for decades.
Unbound DG in its natural form. Least expensive option ($0.50–$1.50/sqft for material). Tracks easily into the house, washes away during rain, and needs top-dressing every 1–3 years. Best for lightly trafficked garden paths and informal areas where you don't expect permanent results. Not recommended for patios or areas near doorways.
DG mixed with a polymer stabilizer (organic or synthetic) that binds the particles into a firmer surface when compacted. Reduces tracking and washout significantly. Costs $1.50–$3.00/sqft for material. Needs top-dressing every 3–7 years. Better than standard DG for patios but still requires ongoing maintenance and is not suitable for furniture-heavy entertaining areas.
DG applied over a resin binder, creating a semi-permeable bound surface. Closest to a permanent hardscape finish using DG. Costs $8–$15/sqft installed — approaching flagstone patio territory. More durable than stabilized DG, permeable to water (good for drainage), but expensive enough that natural stone becomes a more competitive option at this price point.
Longevity is where the cost gap between DG and natural stone pavers becomes most apparent. A properly installed natural stone patio should last 50–100+ years. Decomposed granite surfaces require regular maintenance and periodic replacement.
Standard DG: top-dressing needed every 1–3 years. Full replacement every 5–10 years. Stabilized DG: top-dressing every 3–7 years, periodic maintenance required. DG doesn't "fail" catastrophically — it gradually thins, develops ruts in traffic areas, and washes away in low spots. Over a 30-year period, a DG patio may cost as much in maintenance as a stone patio costs upfront.
Properly installed natural stone on a well-compacted base lasts 50–100+ years. The stone itself is essentially permanent — failures occur in the base (settling) or joint material (erosion), not the stone. Sealed stone requires resealing every 3–5 years. Most natural stone patios in Los Angeles look excellent after 20 years with minimal maintenance beyond occasional cleaning and resealing.
DG: Raking after wind events to level the surface, top-dressing after rain, weed prevention (DG is permeable and weeds push through), and replacement of washed-out areas. Natural stone: Occasional sweeping, annual or biannual power washing, resealing every 3–5 years, and replacing joint sand as needed. Stone is the lower-maintenance option over a 10+ year horizon despite higher upfront cost.
The right choice depends on your specific application, budget, and how long you plan to stay in the property. Neither material is universally better — they serve different purposes well.
✓ Large side yards and utility paths (cost-efficiency matters)
✓ Drought-tolerant California-style landscaping
✓ Dog runs and pet areas (forgiving surface, easy to replace)
✓ Informal garden paths between planting beds
✓ Meditation gardens and Japanese-style landscapes
✓ Rental properties where low upfront cost is the priority
✓ Areas where permeability is legally required
✓ Patios and entertaining areas (furniture-ready surface)
✓ Pool decks (non-porous, easy to clean, no tracking)
✓ Driveways (durable under vehicle weight)
✓ Front entry walkways and visible curb appeal areas
✓ Any area adjacent to indoor flooring (no tracking)
✓ Long-term investment property upgrades
✓ Areas where you want a luxury finish
Large areas where stone would be cost-prohibitive — a 2,000 sqft side yard in DG costs $10,000–$20,000 versus $40,000–$80,000 in natural stone. Combined projects: many LA homeowners use natural stone on their main patio and DG on secondary paths and side yards, getting the aesthetic benefits of stone where they matter most and DG's cost efficiency everywhere else.
Water permeability is a real advantage of decomposed granite that natural stone installation must address through permeable joint materials or permeable base systems.
Standard and stabilized DG are naturally permeable — rainwater passes through the surface directly into the soil. This makes DG a naturally stormwater-compliant surface and an excellent choice for areas subject to California's C.3 stormwater regulations, which require a percentage of new hardscape to be permeable. DG is the simplest way to meet permeable area requirements.
Solid natural stone pavers installed with sand or dry-set mortar joints can be near-impermeable, which may trigger stormwater plan requirements for large patios in LA County. Solutions include: permeable joint sand, open-graded base systems that allow drainage through joints, incorporating drainage channels at low points, or designing drainage swales to manage runoff. Tegula Stone handles all necessary drainage design as part of the installation plan.
LA County and city stormwater ordinances require that development exceeding certain size thresholds manage stormwater on-site. For most residential patios under 500 sqft, individual stormwater requirements are minimal. For larger projects, a permeable paver system or inclusion of DG areas can satisfy permeability requirements while maintaining a premium look. We pull the appropriate permits and handle all regulatory compliance.
