To LuAnn, Frlady, BadWilsonart and anyone else with similar cracking problems, I had the same issue. Only in my case Wilsonart was cooperative and agreed to replace the sink (there's was a fundamental structural problem with the material itself for counters made in the late 1990's and early 2000's).. That's the good news.
The bad news has been on-going since the replacement:
- They sent their local fabricator to replace the sink in 2007 who came with wrong sink about which I was unaware until after it was installed
- The fabricator cut out the sink in my home vs.. outside or in his shop without using any barrier or dust removal equipment leaving behind: A large quantity of particles which in that form have toxic chemicals, a clogged drain with a leaking and broken garbage disposal, and incorrectly installed expensive sink hardware which has been unusable since 2007
- The particles were (and continue to be) distributed throughout my home resulting in extensive damaged and/or destroyed property
- Although admitting their fabricator was responsible for the damage, they refused to clean up the mess.
- I was in litigation for almost 5 years with Wilsonart vigorously defending itself by retaining some of the country's top corporate defense attorneys, leaving me with medical problems proved directly attributable to the chemicals in the home, financially devastated, a 2, 500 square foot home without a working kitchen - and much more going on almost 8 years. A house that can't be legally sold unless and until it's completely remediated (and the very real possibility I will lose it to foreclosure).
It would have cost Wilsonart a pittance to have cleaned seven years ago. Instead they chose to spend what I estimate to be several million dollars to do everything possible not to. It seems to me we're back to a country of robber barons. Please don't buy anything Wilsonart. If anyone would like to see photos, let me know and I'll upload them.
