Granite is one of the hardest and most durable natural stones for outdoor patios — rated 6–7 on the Mohs hardness scale, resistant to heat, staining, and weathering. Professional granite patio installation in Los Angeles costs $20–$45 per square foot installed. A 300 sq ft granite patio lasts 50+ years with minimal maintenance.
Quick Answer: Granite patio installation in Los Angeles costs $20–$45 per square foot fully installed on a mortar bed. A 300 sq ft patio runs $6,000–$13,500. Granite is rated Mohs 6–7 — far harder than most flagstone — and resists heat, staining, and weathering with minimal maintenance. Flamed granite is the recommended outdoor finish for slip resistance.
Granite is an igneous rock formed under extreme heat and pressure, giving it properties that are uniquely suited to the demands of an outdoor patio in Los Angeles — intense sun, occasional heavy rain, and the expansion and contraction of seasonal temperature swings. Here is how granite compares to other popular patio materials.
Granite is significantly harder than limestone (Mohs 3), sandstone (Mohs 3–4), and even most flagstone varieties. This hardness translates directly to scratch resistance, chip resistance, and the ability to withstand heavy outdoor furniture, foot traffic, and vehicle loads without surface damage.
Granite does not fade, discolor, or degrade under UV exposure — critical for LA's 280+ sunny days per year. Unlike concrete pavers, granite's color is mineral-based and runs through the full depth of the stone. In high-heat applications, flamed granite stays cooler underfoot than dark concrete or asphalt surfaces.
A sealed granite patio requires little beyond periodic sweeping and occasional resealing every 3–5 years. Granite does not absorb stains readily, is resistant to moss and algae growth, and does not require the frequent re-sealing that softer stones like limestone and sandstone demand.
Granite comes in a surprisingly wide range of colors: classic grey, charcoal black, warm pink, blue-grey, and multicolor varieties. Grey and black granites suit contemporary and modern homes; pink and warm-toned granites complement traditional and Mediterranean architecture prevalent across LA.
A properly installed granite patio in Los Angeles will easily outlast 50 years with minimal intervention. Granite is used in public plazas, civic monuments, and high-traffic commercial spaces because of its proven longevity. For a residential patio, it represents a generational investment in your property.
Concrete pavers cost less upfront ($8–$18/sqft installed) but fade, chip, and require replacement after 15–25 years. Granite costs more initially but delivers significantly lower 30-year total cost of ownership. For homes where curb appeal and resale value matter, natural granite is the clear winner.
The finish applied to granite profoundly affects its slip resistance, visual character, and maintenance needs. For outdoor patios in Los Angeles, finish selection is one of the most important decisions you will make. Here are the three finishes recommended for exterior use.
Flamed granite is produced by applying a high-temperature flame to the stone surface, causing the crystal structure to burst and creating a rough, highly textured finish. This is the most slip-resistant option — essential for pool surrounds, wet bar areas, and any surface exposed to rain or sprinklers. Flamed finish also masks surface scratches and wear. Highly recommended for all LA outdoor applications.
Honed granite has a smooth, matte (non-polished) surface. It is attractive and elegant, but noticeably more slippery than flamed when wet. Best suited for covered patios, outdoor dining areas under a pergola, or dry-climate applications. Requires more frequent sealing than flamed granite because the smoother surface is more porous. Cost: similar to flamed.
Brushed granite is finished with wire or abrasive brushes after honing, creating a lightly textured surface between honed and flamed in terms of slip resistance. Popular for contemporary and upscale residential projects where a refined look and moderate slip resistance are both priorities. Well-suited to LA's Mediterranean climate and popular in Brentwood, Pacific Palisades, and Hancock Park installations.
Polished granite (mirror-smooth, high-gloss) is not recommended for outdoor patios. The polished surface becomes dangerously slippery when wet and is easily scratched by outdoor furniture, sand, and debris. Polished granite is appropriate for indoor kitchen countertops and interior flooring — not for exterior hardscape in Los Angeles.
Granite patio installation follows a more rigorous process than dry-lay flagstone. Because granite is typically installed wet-set on a mortar bed over a concrete base, proper preparation at every stage is critical for long-term performance. Here is what a professional granite patio installation looks like from start to finish.
Granite patios over 200 sqft installed on concrete bases typically require a permit from LADBS. Tegula Stone prepares permit drawings, handles the application, and schedules inspections — typically adding 1–2 weeks to the project timeline. A clear design plan (layout, pattern, drain locations) is finalized before any excavation begins.
The patio area is excavated 6–8 inches below finished grade to accommodate the gravel base, concrete slab, mortar bed, and granite thickness. In LA's clay soils, deeper excavation and proper drainage planning are critical. The perimeter is formed with lumber or steel forms to contain the concrete pour.
A 4-inch layer of Class II crushed base rock is spread and mechanically compacted in the excavated area. This gravel base provides drainage and stable support for the concrete above. Reinforcing rebar or wire mesh is placed before the concrete pour to strengthen the slab and prevent future cracking.
A 4-inch concrete slab is poured and allowed to cure for a minimum of 7 days before stone setting begins. Control joints are cut into the slab to manage shrinkage cracking. The slab must achieve adequate strength before the weight of the granite and mortar is placed on top.
Polymer-modified mortar is spread on the cured concrete base. Granite slabs or tiles are set in the mortar with proper joint spacing (typically 3/16–1/4 inch for a formal look). Each piece is checked for level and alignment. Cut pieces are fabricated on-site with a wet saw. The mortar bed provides a permanent, stable bond between granite and concrete.
Once the mortar has cured (24–48 hours), sanded or unsanded grout is applied to the joints, packed firmly, and cleaned from the stone surface. After full cure, a penetrating impregnating sealer is applied to the granite. Tegula Stone includes the initial sealer coat on all granite patio installations as part of the project scope.
Granite patio cost depends on granite type and origin, finish, patio size, and site conditions. The table below reflects current Los Angeles market pricing for professional installation on a mortar bed over a concrete base. For a broader stone cost comparison, see our natural stone patio cost guide.
Note: These prices are for professional wet-set installation on a concrete base. Dry-lay granite (set in sand) costs 20–30% less but is not recommended for patios above 300 sqft or areas with vehicle access. Contact Tegula Stone for a free site-specific estimate.
Granite is the lowest-maintenance natural stone patio surface available — but it is not zero-maintenance. Proper sealing and cleaning will keep your granite patio looking exceptional for decades. Here is what to expect.
Seal your granite patio every 2–3 years with a penetrating impregnating sealer. Flamed granite is slightly more porous than polished granite and benefits from more frequent sealing in high-use areas. Test annually by dripping water on the surface — if water no longer beads, it is time to reseal. Tegula Stone includes the initial sealer application on all installations.
Sweep regularly to remove debris, sand, and leaf litter. For routine washing, use a pH-neutral stone cleaner diluted in water — never use acidic cleaners (vinegar, citrus-based products) or alkaline degreasers, as these can etch the stone surface and degrade the sealer. A garden hose and soft brush are sufficient for most regular cleaning. Avoid high-pressure power washing directly at grout joints.
Sealed granite resists most stains, but oil, grease, and tannins (from leaves and wood) can penetrate if the sealer has degraded. For oil-based stains, apply a poultice of baking soda and acetone, cover with plastic wrap, and allow to draw out the stain over 24 hours. For organic stains, diluted hydrogen peroxide applied with a cloth is effective. Always re-seal after any intensive stain treatment.
Check grout joints annually for hairline cracks, which can allow water infiltration. Re-grout affected sections promptly to prevent water from reaching the mortar bed and concrete base beneath. In LA's climate, minor joint cracking is normal due to thermal expansion and contraction. Use a matching sanded grout and apply penetrating joint sealer after any re-grouting work.
