quartz countertop



Quartz is a manufactured product and can be very attractive. The manufacturing process allows a much wider range of colors than you’ll find in natural stones such as marble or granite. The appearance of the finished engineered stone is rich, even luxurious.

Quartz is non-porous so it resists staining much better than granite, marble and concrete. It stands up to juice, oil, wine, tomato, coffee and other sources of stains in the kitchen. Quartz countertop is an ideal choice for a kitchen.

For cleanliness, a non-porous surface means that it will not harbor bacteria or viruses. You can always be confident that you are getting your quartz countertop absolutely clean, and that’s a great benefit in both the kitchen and the bathroom.

Quartz has the same durability as concrete and granite, but is quite a bit more forgiving, so it won’t chip or crack as easily. It doesn’t have the same hardness in the feel that some people find unpleasant. To be the leading in Ottawa slabs for quartz countertops makes us proud.
