In an article posted on the HGTV website it states the many benefits of quartz countertops. One comment however I felt needed a bit more of an explanation. In the article there are comments from both homeowners and contractors who have either purchased quartz or had it installed on the job. One such comment came from Gay:

"Installation is a bit of a pain," says Gay. "You have to obtain it from a (certified) distributor. They send people to measure and then they send installers. There's a bit of a wait involved between each of these steps."

Before this comment the writer of the article stated:

"Despite its many advantages, installation of engineered quartz countertops isn't a job for the average do-it-yourselfer; the companies that make and sell engineered quartz certify their own installation experts."

I personally feel that the reasons for these issues should be clarified. One, because quartz is a warranted product by all if not most brand names, those companies not only warranty the product itself but also the installation work. To be able to control that process they need to certify fabricators to do the installation work so that it is always done correctly. There are incorrect ways to install the quartz countertop that could potentially cause damage.

Another issue is that quartz, like granite, may need to be seamed together in large kitchens. Although this is as simple as applying a glue like mixture to the seam area between two surfaces, it is the color matching process that is a true art. An off colored seam can make or brake the beauty of the countertop and could be a distraction to the eye. You want the color of the seam to blend in to the surface so that it is as inconspicuous as possible. A true professional can do this rather easily and quickly.

Another issue preventing self installation of quartz is the weight of the material. For kitchen countertops you often have long runs of countertop that will be extremely heavy to carry. Full slabs of quartz countertops weigh several hundred pounds, not something the average homeowner should lift or should want to lift.
