They always went above and beyond - came to my house to take measurements, answered all my questions with honesty, and even gave me advice on the layout for my kitchen. All of their employees are professionals, honest and hardworking people. And shoutout to Louis for giving me a very fair price for quality cabinets and countertops. Everything turned out amazing and I am very thankful to have met and done business with these guys. I highly recommend them for all of your project needs!

We had an exceptional experience with AG Custom Countertops installing our granite kitchen counter tops. From start to finish the process was smooth and professional. It took me a while to finally decide on the perfect stone only to learn that there wasn't enough of it in AG's warehouse for our counters. Needless to say I was not thrilled at the prospect of having to make another choice. Knowing how much I like the stone, Louis went the extra mile and located more of it. He really came through for us. The craftsmanship is outstanding - the granite was cut and installed perfectly, seems are clean, and the final result completely transformed our kitchen! If you're looking for high quality work, attention to detail, and great customer service, i highly recommend AG Custom Countertops. We couldn't be happier with the results!
