Can Chipped Quartz Countertop be Repaired?

Quartz countertops are an increasingly popular option for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any other countertop material, quartz can become damaged over time. Small chips and cracks are among the most common issues. Fortunately, minor damage can often be repaired fairly easily. Here is what you need to know about repairing chipped quartz countertops.

What Causes Chips and Cracks in Quartz?

Quartz is an engineered stone made from crushed quartz aggregates held together with resin. This makes it extremely hard and resistant to scratches. However, quartz is not completely invincible. Chips and cracks usually occur due to:

  • Dropping heavy objects on the countertop – This can cause stress fractures or small chips along the impact point.
  • Excessive heat – Exposing quartz to prolonged high temperatures can cause the resin to weaken and the stone to crack.
  • Settling foundation – If the cabinets or base the countertop is installed on settles, it can cause cracking.
  • Improper installation – Seams and edges not properly supported or adhered during installation are prone to chipping.
  • Cuts in the material weaken the structure – Any cutouts for sinks and cooktops are vulnerable to cracks radiating from the corners.

While quartz is less prone to damage than many other countertop materials, chips and cracks do occur, especially along the edges and cutout areas.

Repair Options for Minor Chips and Cracks

For small chips and hairline cracks limited to the surface, DIY repair is often possible. However, severe cracks or damage around cutouts will usually require hiring a professional. Here are the common repair options:

Clean and Use Clear Epoxy

For small chips, you may be able to simply clean the damaged area and fill it with a clear epoxy adhesive designed for stone. Mix the epoxy and apply according to the product directions. This can fill chips up to about 1 inch wide. The repaired area will usually have a visible seam but match the surrounding quartz.

Sand and Refinish

Alternatively, you can carefully sand the chipped edge to create a small bevel or rounded shape. Then apply an epoxy filler and blend it to the surrounding surface. Finish by polishing the repaired section with fine sandpaper. This helps hide the seam.

Professional Patch Kits

There are proprietary quartz repair kits made specifically for filling chips and divots. They contain adhesive patches close to the color and pattern of quartz. A proficient DIYer can follow the kit instructions to cut and adhere a patch. This works best for small edge chips.

Professional Refinishing

For more extensive damage, best results usually come from hiring a countertop refinishing company. They have access to quartz-specific resins and compounds to fill larger cracks and re-polish the surface. Refinishing can often repair significant cracks of 1 inch or longer.

Quartz Replacement

If cracks extend across large sections, a full quartz replacement may be needed. This requires removing and disposing of the damaged slab and installing a new one. Hire a countertop fabricator or replacement company to template, cut, polish, and install the new quartz. Total replacement is often necessary with extreme cracking damage.

Preventing Cracks and Chips

While quality quartz is designed to be durable, chips and cracks are difficult to prevent entirely. But you can minimize damage by:

  • Using cutting boards rather than cutting directly on the surface
  • Placing hot pans and baking sheets on trivets instead of the quartz
  • Cleaning up spills quickly to avoid prolonged exposure to moisture
  • Avoiding hard impacts from objects hitting the edge
  • Inspecting regularly for any cracks near seams and cutouts

With care and prompt repair, minor chips and cracks in quartz can be dealt with effectively. But extensive cracking may eventually call for a full replacement slab.

Frequently Asked Questions About Repairing Chipped Quartz Countertops

Can I repair a chipped quartz countertop myself?

Minor chips and cracks can often be fixed with a DIY repair using epoxy adhesives and sanding/polishing. But significant damage is best left to countertop professionals.

How do you fix a crack in a quartz countertop?

Very small stress cracks can be filled with a clear epoxy. Larger cracks require sanding and refinishing with a quartz-specific patching compound. Severe cracks need replacement.

Does homeowners insurance cover cracked quartz countertops?

Homeowners or renters insurance will sometimes cover repairs if the damage resulted from a covered loss like a pipe leak or foundation settling. But policies have limitations for surface cracks from normal use.

Can you buff out chips in a quartz countertop?

Light buffing with fine-grit sandpaper can help blend small edge chips. But it does not repair deeper cracks that penetrate through the surface. Filling with adhesive is necessary for most chips.

Should I replace or repair a damaged quartz countertop?

Minor chips and cracks can often be repaired successfully. But if damage is extensive across large sections, a full replacement may be needed to restore function and appearance.


Quartz countertops bring durability and beauty to kitchens, but chips and cracks do occur. Thankfully, small damages can frequently be repaired with careful sanding, resin fillers, and refinishing. However, it is important to address any issues quickly before cracks have a chance to expand. With prompt care, most quartz surfaces can retain their flawless look despite years of heavy use.
