I recently had Nu-Tech clean my porcelain tile floors and highly recommend their services. We have a large continuous tile floor that was newly laid in 2001 and has never been professionally cleaned. It's light colored tile with off-white grout. Several areas had gotten grubby and stained, especially in the kitchen, and we had a few small chips and pits that collected dirt. The owner, Mary Ryan, explained that after decades in this business, they have learned that scrubbing the tile by hand, touching up grout color so it all matches, and applying a high quality sealer was the best way to ensure that our floor would look as good as new. She was right and her team did an excellent job - even repairing the chipped areas so well they can't be found anymore! Our floor looks as nice as the day we moved in. read more
