Cosmo borrowed money from me to keep his business afloat and almost immediately told me “I’m beat” after promising to... pay me back using a deposit from a customer. So not only did he not pay me back and never planned to, he was about to use a customers deposit which would have hurt the customer he was doing business for.Since this has happened he has threatened my life and threatened to use my son as a weapon and hurt my custody I already have. Dishonest is a compliment for this man.DO NOT HIRE HIM!!!!read more

110% would recommend. Their customer service and attention to detail was impeccable. Not only did I get a tour of the... showroom and warehouse, they also understood what I wanted and gave me options on a spectrum of prices and weighed the pros and cons of each with me.

Just recently moved to the King of Prussia area and needed some updates to my kitchen. It had outdated granite and a... double sink, which proved to be very impractical for every day use given the dimensions. As I was new to the area I had to rely on reviews online and stumbled across Cosmos Marble and Granite and am certainly glad I did. We used them throughout the entire process and could not have had a better experience from consultation to installation. The staff was incredibly professional and very willing to not only show the different styles of granite in their warehouse but also had extensive knowledge which demonstrated their commitment to their business. Will definitely be using them for our bathroom renovation.read more

Competent work but terrible customer service, rude and arrogant. I would never use them again. They did not install two... sinks (which were not available on site) and refused to provide any price adjustment.read more

I had to remodel the kitchen of my home and I am pleased to have come into contact with this family. Noula and her... family are great at what they do. They care for their customers and make sure they provide them with best customer service. They are genuine, polite and very considerate. I purchased the floor tiles, backsplash, granite and some of the kitchen product from them at a great price. I will recommend them 100% for all kitchen, bathroom products.read more
