Poor workmanship. Not what you expect when paying thousands of dollars for hardwood and tile flooring. Given the distinct impression that installers were there to get the job done as fast as possible. Will never call Taylor flooring again. It is actually quite obvious, if you need a floorist call a floorist, not a Taylor.
Good luck with your floor installations. I'm convinced I can do a better job and I don't install floors for a living.
