Stone pricing varies depending on the material, slab origin, thickness, edge detail, and installation complexity. As a general guide:

  • Granite: Typically more affordable than engineered stone
  • Quartz: Mid-range pricing with consistent colour and finish
  • Porcelain / Sintered Stone (e.g……): Premium pricing due to advanced manufacturing and performance

For accurate pricing, we recommend requesting a quote based on your selected slab, measurements, and project requirements.

In most cases, granite is more affordable than quartz. However, pricing depends on the specific slab, origin, thickness, and fabrication complexity. Some premium granites can cost more than entry-level quartz.

The most common countertop thicknesses are:

  • 20mm: Sleek, modern, and suitable for most kitchens
  • 30mm: Premium look with added visual weight
  • 12mm porcelain: Often used with mitred edges for a thick appearance

Your choice depends on design preference, budget, and cabinetry support.

Yes, natural and engineered stone can chip or crack if subjected to heavy impact, structural movement, or incorrect installation. However, professionally fabricated and installed stone surfaces are extremely durable and suitable for long-term use.

Yes. Natural granite is porous and should be sealed to protect against staining and moisture absorption. Sealing frequency depends on usage and the specific granite type, typically every 1–3 years.

Quartz and porcelain do not require sealing.

With proper care, stone countertops can last decades—often a lifetime. Granite, quartz, and porcelain are among the most durable surface materials available for kitchens and bathrooms.

Yes. Many chips, cracks, and scratches can be repaired by professional stone technicians using specialised resins and polishing techniques. Severe damage may require partial replacement, depending on the slab and installation.

Quartz:

  • Engineered stone made from natural quartz and resin
  • Non-porous and highly consistent in colour
  • Excellent for indoor applications

Porcelain / Sintered Stone:

  • Manufactured under extreme heat and pressure
  • Ultra-durable, UV-stable, and suitable for indoor and outdoor use
  • Thinner and lighter than traditional stone

Natural stone and porcelain are highly heat resistant. Quartz is heat resistant but contains resin binders, so prolonged direct heat exposure is not recommended.

While granite and porcelain can withstand high temperatures, we recommend using trivets or heat pads to prevent thermal shock or surface damage—especially on quartz surfaces.

Yes. We offer removal and disposal of existing countertops as part of our installation service, subject to site conditions and project scope.

Lead times vary depending on slab availability, project complexity, and current production schedules. Typically:

  • Template to installation: 7–21 working days
  • Large or custom projects may require additional time

We prioritize reliable supply and professional project timelines.

We provide warranties on fabrication and installation workmanship. Manufacturer warranties apply to engineered stone and porcelain products. Warranty terms vary by material and supplier—please contact us for full details. Our Teramo Quartz ™ carries a 25-year limited warranty.

Yes. Granite and porcelain are excellent for outdoor applications and withstand UV exposure, temperature changes, and coastal conditions. Quartz is generally recommended for indoor use only due to UV sensitivity.
