On average, the cost to install a quartz slab ranges from $150 to $280 per square foot, with the price fluctuating based on the number of slabs of quartz and any additional finishes. For example, homeowners will find that the cost increases as they add detailed edging fabrications or request extra fixture and sink cutouts. Here are some of the typical steps that factor into the cost of installing a quartz countertop:
Leveling - Before installing a quartz countertop, a professional may need to level the cabinets so that they reduce the risk of cracking and gaps. Typically, an experienced professional will use a sander or a saw to lower cabinet height to the proper level, or add shims to elevate the height for an even surface.
Adding supports - The installation expert may need to add supports for the countertop in areas that do not have cabinetry, such as above a dishwasher. Most often a contractor will do this by securing pieces of sturdy wood to the wall or to neighboring cabinets on either side of the appliances.
Fabrication - Countertop fabrication is the process of cutting and finishing the countertops to a desired size and shape. This process often includes inspection of the slab, template layout, cutting the slab to size, fabricating the edges to a specific treatment, and then polishing the slab. The fabrication process also typically includes fixture and sink cutouts, following the template to match the design for the home.
Seam jointing - As most kitchens with a lot of counter space require at least one seam, the installation process will include seam joining. During the fabrication process, the manufacturer will often work with the homeowner to decide just where the seams should go. Upon installation, the professional will do a 'dry fit' to make sure everything lines up properly, make any final adjustments, and then join the seams with an epoxy.
Estimating the cost of installation for a quartz countertop comes down to knowing the price per square foot, as well as measuring the countertop space. For example, a countertop that measures about 25 square feet can cost a homeowner between $1,200 and $2,700 after purchasing the quartz and paying installation fees.
