How Much to Cut and Polish Quartz Countertops

Quartz countertops are becoming increasingly popular in homes due to their durability, aesthetics, and low maintenance. When installing new quartz countertops, proper cutting and polishing are crucial steps to achieve a flawless finish. This comprehensive guide will provide insights into how much it costs to cut and polish quartz countertops professionally or DIY.

Understanding Quartz Countertops

Before delving into the specifics of cutting and polishing costs, it’s helpful to understand what quartz countertops are and what makes them unique.

Quartz countertops, also known as engineered stone countertops, are made from ground natural quartz crystals combined with polyester resins and pigments. The resins bind the quartz particles together to form a durable, non-porous slab.

Compared to natural stone countertops like granite and marble, quartz offers superior durability and stain resistance. The resins make quartz resistant to scratches, heat, and acids. Quartz requires very little maintenance compared to natural stone.

The addition of pigments allows quartz slabs to mimic natural patterns and colors of stone while offering consistent coloring throughout. This makes cutting and polishing quartz a much more predictable process than natural stone.

So in summary, key benefits of quartz countertops include:

  • Extremely durable and scratch-resistant surface
  • Stain and acid-resistant
  • Low-maintenance
  • Consistent patterning and colors
  • Resists heat better than natural stone

With proper fabrication, quartz countertops can provide many years of beauty and hassle-free use. Paying for professional cutting and polishing is important to bring out the best in your investment.

Factors That Determine Quartz Cutting and Polishing Costs

Several variables affect the total costs of cutting and fabricating quartz countertops:

Size of the Job

The more surface area needing cut and polished, the higher the labor time and overall costs. Larger kitchens with more countertop square footage, backsplashes, and islands will be more expensive than a small project.

Edge Profiles

The edge style chosen affects complexity and costs. Elaborate edges like triple bullnose take more time than a simple eased or beveled profile. Unique custom edge profiles are typically the most expensive option.


Seams are necessary when the desired countertop sizes exceed the maximum slab dimensions. More seams means more cutting and polishing work. Good fabricators minimize seams through optimal layout planning.

Sink Cutouts

Cutting holes for undermount sinks adds cutting time and complexity versus a standard countertop with no penetrations. Expect higher costs for projects with multiple sink cutouts.


Including a full backsplash along walls adds more linear feet of cutting and polishing. Partial backsplashes cost less than full-height backsplashes.


Quartz slabs come in standard thicknesses of 2cm or 3cm. The thicker the material, the more cutting time required, increasing overall fabrication costs.

Site Conditions

Challenging installation conditions like narrow doorways, stairs, or high-rise locations can lead to higher job costs. Easy ground-floor access reduces material transport and labor costs.

With an understanding of the key variables, we can now examine typical price ranges.

Average Costs for Professional Cutting and Polishing

Hiring professional quartz fabricators and installers is the best way to achieve flawless, long-lasting results. On average, expect to pay the following for qualified specialists:

  • Quartz Material Costs: $50 – $120 per square foot
  • Fabrication Labor: $40 – $100 per square foot
  • Installation Labor: $10 – $30 per square foot

So for a 30 square foot quartz countertop project quoted at $80 per square foot for materials, $70/sq.ft fabrication, and $20/sq.ft installation, the total would be approximately:

  • Materials: 30 sq.ft x $80 = $2,400
  • Fabrication: 30 sq.ft x $70 = $2,100
  • Installation: 30 sq.ft x $20 = $600
  • Total = $5,100

On a larger 60 square foot project with premium $120/sq.ft quartz, $100/sq.ft fabrication and $30/sq.ft installation, the totals work out to:

  • Materials: 60 sq.ft x $120 = $7,200
  • Fabrication: 60 sq.ft x $100 = $6,000
  • Installation: 60 sq.ft x $30 = $1,800
  • Total = $15,000

As you can see, costs add up quickly on larger projects with premium materials and edge profiles. Reputable fabricators charge fair prices to cover their extensive expertise and equipment investments.

Always get every included service clearly specified in a written quote. Photos of past work and multiple customer references can help identify the best professionals for the job.

DIY Quartz Countertop Cutting and Polishing

With proper planning, tools, and techniques, DIYers can cut and polish their own quartz countertop slabs. This is only recommended for experienced DIYers comfortable operating specialized power tools.

Be aware that poor cuts and polishing can lead to cracked slabs or countertops that don’t properly fit the space. Damaged slabs cannot be returned and mistakes become very costly. Consider practicing on scrap pieces first.

DIY Tips for Cutting and Polishing Quartz

Homeowners determined to fabricate their own quartz countertops can reduce risks and improve results with these DIY tips:

Choose 2cm Slabs – Thinner 2cm slabs are lighter and easier to cut than 3cm material. Preventing cracks on thick slabs requires more cutting force.

Use Adhesives at Every Seam – Apply adhesive along the entire length of each seam during assembly. This prevents gaps and separation over time.

Follow Safety Protocols – Wear eye protection, respirators, and gloves when cutting and polishing. Keep fire extinguishers nearby due to quartz dust flammability.

Make Test Cuts First – Practice on scrap pieces to set the blade depth and feed rate before attempting real cuts. This dialing in saves slabs.

Check Dimensions – Use a template of the countertop shape over the slabs to confirm sizing. Account for overhangs in the templates.

Go Slow on Sinks – Precut the sink holes undersized, then use a router with a diamond flush-cutting bit for final sizing. Avoid over-cutting.

Begin with a 60-Grit Pad – Start polishing pads at 60-grit, followed by 200-grit, then 400-grit for the final smoothness. Avoid skipping grits.

Apply Even Pressure – When polishing, use consistent pressure and overlapping passes across the slabs. Re-polish any noticeable uneven spots.

Seal After Installation – After installing the countertop, apply a penetrating quartz sealer to protect from stains. Reseal every 2-3 years.

Careful planning, patience, and proper techniques can lead to satisfying DIY quartz fabrication. But most homeowners are still better off letting the professionals handle this precision work.
