How Much to Fix a Crack in Quartz Countertop

Quartz countertops are an increasingly popular choice for modern kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any solid surface, quartz can develop cracks over time. Fixing a cracked quartz countertop properly is important for restoring its structural integrity and appearance. Here is a comprehensive guide on how much it costs to repair cracks in quartz countertops.

What Causes Cracks in Quartz?

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

  • Impact – Dropping a heavy object on the countertop can cause impact cracks. Quartz is extremely hard and durable, but a significant impact can cause damage.
  • Thermal Shock – Exposing quartz to sudden and extreme temperature changes, like pouring boiling water on it or placing hot pans directly on the surface, can cause cracks due to rapid expansion and contraction.
  • Tension – Improper installation or unsupported overhangs can create stresses that lead to cracks over time.
  • Substrate Movement – Shifts in the cabinetry or substrate that the quartz is installed on can also create cracks in the countertop.

Factors That Affect Quartz Crack Repair Cost

Several factors determine how much it will cost to repair a cracked quartz countertop:

Size of the Crack

The longer and wider the crack, the more extensive the repair work will need to be. Small hairline cracks or chips under 3 inches are cheaper to fix than long deep cracks.

Crack Location

Cracks along the edge or in corners are easier to repair than cracks in the middle of a countertop span. Cracks near sinks, cooktops, and other cutouts also complicate repair work.

Color Pattern

Solid color quartz is the easiest to patch and blend repairs. However, quartz with busy veining, speckles, or swirls makes a perfect color match more difficult and costly.


Cracks in high-traffic zones or areas with limited work space can add labor costs for removing/replacing items to access the damage.

Professional vs. DIY Repair

Hiring a professional to repair the crack will be more expensive than a DIY kit, but gives the best results. DIY repairs are not advised for major cracks.

Repair Cost Estimates

Here are ballpark figures for professional quartz countertop crack repair costs:

  • Small chips under 1 inch – $100 to $200
  • Minor edge or surface cracks under 3 inches – $200 to $400
  • Medium cracks 3-6 inches on edges – $400 to $800
  • Long cracks over 6 inches in span – $800 to $1,500
  • Major cracks across the surface – $1,500 to $2,500
  • Cracks near cutouts like sinks – Add $200 to $500+
  • Cracks in high-traffic areas – Add $100 to $300+
  • Color-matched epoxy resin repairs – Add $100 to $500+

Keep in mind costs vary widely based on local rates and the specific details of your repair project. Get 2-3 quotes from countertop repair specialists before deciding on the best solution.

DIY Quartz Crack Repair Kits

For minor chips and cracks, DIY quartz repair kits can provide an affordable option starting at $30-$60. These contain special epoxy resins you mix and fill the crack with using provided tools. However, achieving seamless results requires skill and the right color match. DIY repairs are not recommended for major cracks.

When to Replace Instead of Repair

In some cases, a cracked quartz countertop may be beyond repair and need a full replacement. This is typically true if:

  • Multiple large cracks are present
  • Severe structural damage is evident
  • The crack location makes repairs highly challenging
  • You want a fresh new countertop look and style

Full quartz countertop replacement costs $60 to over $100 per square foot installed.

Preventing Cracks in Quartz

The best solution is to avoid cracks in your quartz countertops altogether through proper care:

  • Use cutting boards and hot pads to protect from impacts and hot items
  • Clean spills quickly to prevent moisture damage
  • Avoid exposing quartz to sudden temperature extremes
  • Have supports installed for long overhangs
  • Ensure proper installation and sealing to prevent cracks from developing

The Bottom Line

Fixing a crack in a quartz countertop runs anywhere from $100 for a minor repair up to $2,500 or more for a major crack, depending on the specifics. For severe damage, a full replacement may be better than attempting repairs. With proper care and maintenance, you can help avoid costly quartz countertop cracks in the first place.

FAQ About Repairing Cracks in Quartz Countertops

Can I repair a cracked quartz countertop myself?

Minor chips and surface cracks under 3 inches can potentially be repaired yourself using a DIY quartz repair kit with epoxy resins. However, proper color matching and getting invisible seams takes skill. Larger cracks are best left to professionals.

How long does quartz crack repair take?

A professional quartz crack repair job typically takes 2-4 hours depending on the size. DIY repairs may take longer due to the epoxy cure time. The area will need 24-48 hours before regular use.

Should I replace instead of repairing my cracked quartz?

If you have extensive cracking damage across large sections, it likely makes more sense to replace the whole countertop instead of repairing. Also consider replacement if the current style is dated.

Does quartz repair permanently fix cracks?

When done properly by a professional, the repaired section should be structurally sound and last as long as the original quartz surface. DIY jobs have a higher risk of failure over time.

Can cracks reappear after quartz repair?

If the underlying cause of the crack is not addressed, such as incorrect support, movement in the substrate, or tension cracks, new cracks may form again near the repaired section.

Will repaired cracks in quartz be noticeable?

With expert workmanship and color-matching, repairs to chips and minor cracks can be made practically invisible. However, extensive repairs may leave some visible seams.


Cracks and chips in quartz countertops, while frustrating, can be repaired in most cases based on the extent of the damage. Costs range from a few hundred dollars for minor repairs up to several thousand for full-length crack repairs or replacement. To get the best results with seamless appearance, hiring a professional fabricator is advisable over DIY methods. With proper care and maintenance, quartz countertops can provide many years of beauty and durability with minimal cracking issues. Regular inspections and prompt repairs can help keep your quartz surfaces looking pristine.
