Prefab Granite was a great, organized company to work with. Angel’s design abilities and flexibility guided us thru the design process. He answered our many questions and guided us thru the building process. The building was completed before our expected dates. The installers for both the wood cabinet and the fabricators for the countertop were on time, hard working, friendly, and respectful. We enjoyed dealing with both groups. I would definitely recommend Prefab to anyone I know who is remodeling their bathroom. No one would be disappointed with Prefab as their choice. A great company!

The customer service at Prefab Granite Depot has been exceptional. The entire staff that I have interacted with from Martha, Angel, to Waiss have all been super friendly and knowledgeable. I have had some unforseen issues in other aspects of my renovation that delayed having the space ready for Prefab Granite Depot to do the kitchen install. Prefab Granite Depot has been very understanding and adjusted their schedule to accommodate these changes. It really has been a relief to work with such an outstanding and understanding company. They have spent a lot of time working on my behalf, whether it be to find suppliers that have specific products I am looking at, to trying to source the best pricing, to making modifications to our kitchen design. Highly recommend working with this team 🙏

Thank you, Sameer “Sammy,” for the wonderful 5-star review and for recognizing Martha, Angel, and Waiss. We’re so glad we could accommodate your changing schedule and help with sourcing, pricing, and design modifications during your renovation. Your recommendation means a lot to our team and we appreciate you trusting us to make the process easier. We’re here if you need anything else.
