Cracks & Chips
Granite, quartz (like Caesarstone), and concrete countertops can crack or chip—especially near corners or sink cutouts. Concrete often gets small cracks as it cures. Dropping a heavy pot on quartz or granite can chip the edge. Poor cabinet support underneath makes this worse.
Stain
Marble stains easily from wine, coffee, or lemon juice because it's very porous. Even light-colored quartz (like MSI Frost White) can stain if the surface resin breaks down. Natural stone needs sealing every 6–12 months to block stains.
Separated Seam
Seams in quartz or solid surface countertops (like Corian) can split if the cabinets shift or if glue fails. Seams should be very thin—around 1/16 inch. Heat near the seam or moisture can cause glue to loosen, especially with cheaper adhesives.
Heat Damage
Quartz can burn if a pan over 300°F is placed directly on it—the resin can melt. Laminate brands like Formica or Wilsonart can bubble or discolor at just 150°F. Only granite or soapstone can safely handle high heat, but it's still best to use trivets.
Water Damage & Warping
Wood countertops like butcher block can swell, crack, or grow mold near sinks if not sealed. Laminate countertops with a particleboard base can bubble or peel when water gets in the seams—this can happen in just a few months without good caulking.
Scratches and Surface Wear
Soft materials like soapstone, laminate, and Corian can be scratched from daily use. Even sliding a pot or utensil can leave marks. Quartz and granite are harder and more scratch-resistant, but still not scratch-proof. Over time, surfaces can dull without care.

Their team installed a stunning white quartz countertop with a waterfall edge, and it instantly elevated our space. Customers compliment it daily.

"We remodeled our kitchen last fall and hired LA Custom Granite Quartz Marble for our new granite countertops. From the first consultation to the final polish, everything was smooth. The Black Galaxy granite we chose looks incredible and has held up great with our busy family. They really know their materials and guided us every step of the way!"

"Managing over a dozen rental units means I need vendors who are reliable and efficient. LA Custom has become my go-to for countertop replacements in kitchen and bath remodels. They’ve worked on four properties already — always on schedule, on budget, and the finish is top-notch. Their quartz options are perfect for rentals: modern, durable, and easy to maintain."

Quartz just needs soap and water; no sealing required. Granite and marble should be sealed every 12–18 months.
