What to Know Before Installing Quartz Countertops

Tools and Supplies Needed

Installing quartz countertops requires specific tools and supplies like:

  • Safety gear – gloves, eye protection, knee pads
  • Tape measure
  • Level
  • Screws
  • Silicone caulk
  • Shims
  • Saw – wet saw or circular saw with diamond blade
  • Sandpaper
  • Router (for cutouts)

Hire a Professional or DIY

Quartz countertop installation can be done as a DIY project if you have the tools, time, and experience. However, the process involves precise measurements, cutouts, and seam placement. Hiring a professional installer is recommended for most homeowners.

Pick an Experienced Fabricator

Have your quartz slab fabricated and cut to size by an experienced fabricator. They have the special equipment to precisely cut your slabs.

Measure Carefully

Take very precise measurements of your existing countertops and cabinets. Any mistakes in measuring can lead to gaps or misfits when installing.

Plan Seam Placement

Seams will be necessary for large countertops. Plan the layout to minimize seams and place them inconspicuously.

Schedule Enough Time

Make sure to schedule enough time for installation, especially if doing it yourself. Rushing can lead to mistakes. Most DIY installs take 2-3 days.

Step-by-Step Process for Installing Quartz Countertops

Follow this general process for proper quartz countertop installation:


  • Clear countertop area of all objects
  • Turn off electrical and gas connections if needed
  • Clean and level the cabinet bases
  • Apply painter’s tape along the walls to protect them

Dry Fitting

  • Place the pre-cut quartz slabs on the cabinets to test the fit
  • Use shims to adjust for any unevenness in the base cabinets
  • Check that seams align properly and slabs are level

Securing the Slabs

  • Lift slabs off and apply thinset mortar to cabinet tops
  • Carefully lower slabs into place, pressing down firmly to adhere
  • Use shims and screws to secure in place temporarily

Sealing the Seams

  • Clean the quartz edges that meet at seams
  • Apply silicone caulk along the seam and smooth for a watertight seal

Finishing Touches

  • Allow caulk to fully cure
  • Remove shims and screws
  • Clean away any residue or excess materials
  • Reinstall sink, faucet, backsplash and appliances

Optional: Make cutouts for a sink or appliances using a router prior to securing slabs. This step requires skill and the proper bits.

FAQs about Installing Quartz Countertops

Is any special equipment needed to install quartz?

Yes, you’ll need tools like a wet saw, circular saw, router, and clamps. Most DIYers don’t have access to this professional equipment.

Can quartz countertops be installed directly over laminate?

No, existing laminate countertops must be removed prior to installing quartz. The quartz needs a very solid, smooth, and level base.

Should backsplashes be installed before or after quartz countertops?

Backsplashes go up the wall behind countertops and should be installed after. This allows an easy continuous seal between the quartz surface and backsplash.

How long does quartz countertop installation take?

The overall process takes 2-3 days for most DIY installs. Hiring a professional team can shorten installation time to just 1 day in some cases.

Can quartz seams be completely invisible?

With a skilled fabricator and installer, seams can be very tight and hardly noticeable. But some seam visibility is generally expected with quartz.

Is it a bad idea for a beginner DIYer to install quartz?

Quartz installation is quite difficult for a beginner DIYer. The precision cutting, seams, and heavy material make hiring a pro advisable.


Installing new quartz countertops provides a sleek and modern update to any kitchen or bath. While the process involves careful planning and effort, the gorgeous and durable finished result is well worth it. Focus on hiring professionals for fabrication, purchasing the necessary supplies, taking precise measurements, and following essential installation steps. With some patience and attention to detail, you can have stunning new quartz countertops that will last for many years.
