Can You Repair Chipped Quartz Countertops?

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can become damaged over time. Small chips and cracks can occur from dropped objects, bumping into the edge of the countertop, or excessive pressure. When this happens, many homeowners wonder if it’s possible to repair a chipped quartz countertop, and what the best methods are.

What Causes Chips and Cracks in Quartz?

There are a few common causes of chips and cracks in quartz countertops:

  • Impact: Dropping a heavy object onto the countertop can cause chips, especially on the edges and corners. Pots, pans, and appliances are common culprits.
  • Scratches: Cutting or scraping across the surface with sharp objects like knives can scratch and chip the quartz.
  • Thermal Shock: Exposing the quartz to extreme temperature swings, like setting a hot pan on it, can cause the quartz to expand and contract too quickly, leading to cracks.
  • Settling: Minor settling of cabinets and supports under the countertop over time may lead to stress fractures.
  • Fabrication Defects: Small natural fissures or weak spots in the quartz material itself that develop into cracks later on.

Can You Repair Chipped Quartz Countertops?

The good news is that yes, it is possible to repair chips, cracks, and scratches in quartz countertops. However, the ease and results of the repair depend on the extent of the damage.

Small chips, scratches, and hairline cracks can often be repaired fairly easily and inexpensively. But larger chips and cracks may require a professional quartz fabricator to achieve the best results.

DIY Quartz Chip Repair

For minor chips and cracks, there are DIY quartz countertop repair kits available. These contain coloring compounds and clear resins that can fill small defects in the quartz. The steps for repair are:

  1. Clean out the damaged area thoroughly and dry it.
  2. Mix the coloring compound to closely match the quartz color.
  3. Fill in the chip or crack with the colored resin.
  4. Use a razor to scrape flush any excess.
  5. Cure with a UV light if needed.
  6. Buff and polish until smooth.

When done properly, the repaired area can become nearly invisible. But DIY repairs may not achieve a perfect color and finish match.

Professional Quartz Repair

For more significant damage, or if you want flawless results, professional quartz repair is recommended. Qualified technicians have access to:

  • Premium color-matched resins.
  • Tools to cut out and replace large damaged sections.
  • Specialized polishing equipment.
  • Experience matching the finish and pattern of the quartz.

They can fill larger chips, rebuild broken corners or edges, or replace sections. The results can make damage virtually disappear.

What is the Cost to Repair Quartz Countertops?

For minor DIY chip and scratch repairs, expect to pay $20-40 for the repair kit. Professional repairs cost more:

  • Small chips or cracks: $100-200
  • Section replacement: $200-400
  • Edge or corner reconstruction: $300-500+

Get an estimate from a technician before starting repairs. The exact cost depends on the repair needed.

Tips to Prevent Damage to Quartz Countertops

While quartz is very durable, chips and cracks can happen. Follow these tips to help prevent damage in the first place:

  • Use cutting boards and hot pads to protect the surface.
  • Clean spills quickly to avoid stains.
  • Avoid exposing quartz to very high temperatures.
  • Don’t place excess weight on edges or overhangs.
  • Have appliances installed properly to prevent stress.
  • Follow the manufacturer’s care and maintenance guidelines.

With some care and timely repairs when needed, quartz countertops can remain beautiful and functional for many years before needing replacement. Knowing that chips and cracks can be repaired is reassuring for most quartz owners. Seek help from a professional fabricator or installer if you need more significant repairs.

Frequently Asked Questions About Repairing Quartz Countertops

Can I repair quartz myself or do I need a professional?

Small chips and scratches can be repaired yourself using color-matched kits. But for repairs beyond minor issues, hiring a professional quartz technician is recommended to get the best results.

How long does quartz countertop repair take?

DIY repairs take 1-2 hours. Professional repairs can take several hours for larger repairs, or resurfacing an entire countertop. Most shops can complete repair work in 1-3 days.

Does quartz get weaker as it gets older?

No, quartz does not become more prone to damage as it ages. It retains its durability and strength over time. However, improper installation or excessive impact can cause cracks regardless of age.

Can you buff out scratches in quartz?

Light superficial scratches may be gently buffed out using fine grit sandpaper and a quartz polish compound. But deeper scratches and chips expose the underlying resin and require filling for best results.

Is heat damage to quartz countertops permanent?

Exposure to excessive heat can cause permanent damage if the resin binder melts and results in cracks or discoloration. But light heat damage can sometimes be sanded and polished out by a pro. Preventing thermal shock is ideal.


Chips, cracks, and other surface damage to quartz countertops can happen despite the material’s renowned resilience. Thankfully, most types of damage can be repaired by a skilled professional or yourself for smaller defects. Repairing quartz extends the service life, preserves the value of your investment, and keeps your counters looking pristine. With proper care and prompt repairs when accidents happen, you can enjoy beautiful, functional quartz countertops for many years.
