Frequently Asked

Answers before
you call.

Bluestone or travertine?

Bluestone is denser and darker; travertine is lighter, cooler underfoot, and popular around pools.

Does bluestone stain?

Thermal bluestone is dense and stain-resistant. Sealer helps for oil and wine.

Thermal or natural-cleft bluestone?

Thermal is flame-finished and uniform — best for pool decks and modern patios. Natural cleft has texture and variation — better on traditional homes.

Does bluestone need sealing?

Not structurally. A penetrating sealer helps with staining and color depth on dining and grill areas.

Can bluestone go over concrete?

Yes, when the slab is sound and drains properly. We mortar-set over concrete and mud-set or dry-lay over base stone.
