Our Community Says

“They did a great job on my driveway… I would highly recommend them!!!”

— Sean

“After calling five companies, only two called back: one was rude, but Gemini called the next day to set up an appointment. Jay was great to talk with, asked all the right questions, and helped put our vision. We got the quote within two days, beating the other. They stuck to schedule and did an amazing job. The crew was polite, hardworking, and finished the driveway in great time despite the heat. We’re definitely happy we chose Gemini and highly recommend them. Thank you for the great service!”
