I too had installation issues with Duraceramic, as the tile cracked and broke. Congoleum's warranty inspector said the wrong adhesive was used; hardly my fault.
The retailer I had used had gone out of business, so Congoleum offered to replace the tiles, failing to know they no longer offered the black and white. So I asked for the cost of new tiles Nov 10, 2017, and have been ignored. Worst of all, they have not yet responded to the yellow staining of the white tiles and excessive chipping...which have nothing to do with installation. I followed the instructions carefully, supplying the extensive list of dox, including invoices, photos, and so forth.
In the age of social media, it is surprising the company would ignore a request for compensation that was hardly a big deal. What is the price of customer satisfaction?
Reason of review: Warranty issue.
Monetary Loss: $1448.
Preferred solution: Partial payment of replacement tiles and labor..
I didn't like: Getting no answer from them.
