Bluestone flagstone prices
Bluestone flagstone prices are $300 to $500 per ton. This flagstone type lasts 35 to 50 years or longer but requires a sealant for longevity. The naturally anti-slip surface is also fade-resistant for long-lasting visual appeal. However, this stone type becomes hot during the summer.
Granite flagstone prices
Granite flagstone prices are $600 to $750 per ton. Most granite lasts 40 to 50 years or longer due to its resistance to scratching and cracking. This stone has a vast color selection, an anti-slip surface, and durability in all climates. However, sealant is essential to maintain its longevity.
Limestone flagstone prices
Limestone flagstone prices are $250 to $400 per ton. Limestone comes in many colors that resemble marble. Limestone lasts up to 50 years but requires a sealant. This stone is easy to scratch, so it's unsuitable for paving high-traffic areas unless it has a rough surface to hide minor abrasions.
Sandstone flagstone prices
Sandstone flagstone prices are $250 to $750 per ton. Sandstone has unique colors and stripes, like the popular pavers called "Arizona flagstone". These stone pavers last 20 to 50 years on average and require regular resealing. While susceptible to scratches, the anti-slip surface adds safety.
Slate flagstone prices
Slate flagstone prices are $475 to $700 per ton. Slate lasts 50 to 100 years and has excellent anti-slip properties. While slate resists staining and fading, it requires a sealant to prevent etching from acid rain or acidic liquids like spilled red wine. Summer heat can significantly warm slate.
Quartzite flagstone prices
Quartzite flagstone prices are $300 to $600 per ton. Quartzite offers enduring colorfastness, an anti-slip surface, and lasts 50 to 100 years or longer. Sealant is necessary, and this type is harder to cut than other flagstone types.

What is flagstone?
Flagstone is any natural stone from 12" to 36" wide and a thickness generally between 0.5" to 2.0". These stones are mostly sedimentary rock, known for absorbing more water than most other stone types. The most common flagstones are slate, sandstone, quartzite, bluestone, and limestone.
Is flagstone more expensive than pavers?
Flagstone is more expensive than regular pavers because it is naturally sourced and not available in all locations, so shipping flagstone costs extra. Pavers cost $2 to $4 per square foot on average for manufactured materials like brick, concrete, or plastic tiles.
How much does a pallet of flagstone weigh?
A pallet of flagstone weighs 1.50 to 2.25 tons, depending on the stone type, thickness, and pallet size. Always check with the supplier for the exact weight.
Does flagstone need to be sealed?
Professionals recommend sealing flagstone to protect it from staining, cracking, and discoloration. However, some people choose to enjoy the natural finish and gradual color changes of unsealed flagstone.
Is flagstone slippery when wet?
Most flagstone is slippery when wet because of its smooth and porous surface. You can solve this problem by using a textured sealant. Alternatively, ask for anti-slip flagstone varieties with a rough-cut surface like sandstone, quartzite, slate, granite, or bluestone.
How to clean flagstone?
Clean flagstone by first sweeping with a broom to remove debris. Next, scrub the surface with a brush and mild detergent solution. Then rinse the surface with water and allow it to air dry. Avoid using highly acidic soaps that can etch the stone, especially on flagstone types like slate.
