GNL Granite Design | Stone Countertops in Slidell

GNL provided the best service from start to finish! Both my husband and I made several trips to GNL in search for our perfect countertop and were met with patience and understanding. They did a great job of explaining everything from the material to the installation. The install went effortlessly and the end result is absolutely stunning! We are so pleased and will definitely be back for future projects.

GNL was wonderful to work with for my kitchen installation. I knew what I wanted and was only looking for a fair price and professional service. They exceeded everything I expected. Not only did they have a wide range of product, they were helpful and went above and beyond at every turn. I would 100% use them again for any of my projects.

We love our new Quartz countertops in the kitchen and bathroom. Exactly what we wanted. The installers were super careful to install and seal seams. Can barely see them. Highly recommend Marrianna in sales.

What a GREAT team to work with! The products they offer are beautiful!! Their prices are fair. All of their staff members we encountered were courteous, professional and communicated every step of the way with us through out the process. They also offer financing through Wells Fargo. They use some sort of laser measurement system that provided an exact fit for the countertops in my kitchen and both bathrooms!! The installation crew were skilled and were so meticulous with their work. The care they took was as if they were installing in their own home! I am beyond pleased with the quality of the work provided by GNL Granite!! I’m so glad I found them and you will be, too. I wish there was a rating higher than “5” to give this outstanding company!!!!

We are beyond thrilled with the finished product!! During the entire process of choosing the material, the style, and the color, we were treated by the entire staff as family! We happened upon this gem in Slidell, Louisiana, one Saturday afternoon, actually after hours for GNL. We were welcomed with open arms and received the entire tour and special treatment as though we had scheduled an appointment! We knew then we were in the right place!! What a Blessing!! As first-time personal home builders (on a tight budget) we had no idea where to even begin. We had our own personal guide, one of the owners of GNL, Natalia, who made every part of the process painless. She knew all the questions to ask to narrow down exactly what we were looking for!! We could not have asked for anything better!! W
