Misrepresented services and tried to seam a small countertop to save them materials but charged for a custom countertop. Although we were refunded, it took alot of work to get the refund. Really disappointed that Lowes is using them for their customers.

We ordered our countertops from Lowe's who use Granite World of Colorado as a supplier. We had a great experience with Granite World. Excellent communication, exceptional product quality, and expert installers. 10 out of 10!

I would give negative stars if I could. Granite World should not be in business, full stop, let alone a contractor for Lowes. They had a very simple job to do for us - deliver two pieces of granite - and they have messed it up three times now. First, they broke a piece. Second, they tried to pawn a glued-together piece off on us as a new cut (and lied about it). Third, they mis-measured the final piece so badly it was off by one inch. Their communication throughout has been poor, rude and uninformative. Go anywhere else, but do not use Granite World, nor Lowes for your granite.

We recently had the pleasure of working with Granite World of Colorado for new stone countertops. As newcomers to the various stone options, their team provided exceptional service, patiently explaining the pros and cons of different materials. They guided us through the selection process at multiple warehouses, ensuring we found the perfect type and color. Granite World handled everything seamlessly—from measurement to fabrication and installation—without any issues. Now, our kitchen feels brand new, bright, and inviting. We're grateful to Granite World for delivering such fantastic results and recommend them for the best beautiful stonework!!!

I would like to thank Ashley H, for her help, information, understanding and patience’s. I have talked with other companies, including large chain hardware stores about countertops. Ashley and Granite World can save you a great deal of money while providing a quality product. One company quoted me 40% more for the same material and work. Ask questions and listen. I will never go anywhere else again.

My Parents recently had a kitchen remodel and we used Granite World for all of our countertop needs. We were extremely impressed with the professionalism, pricing, quality of stone and precise installation. The communication throughout the process was impeccable and my mom was reassured and put at ease during the construction as Ashley and the rest of the staff were always so quick to answer any questions. The installers were superb and so respectful and EXCELLENT. My mom knew she was in good hands from the start and her kitchen is completely transformed. The quality of work done was very impressive. We also loved the variety of stone to choose from that fit within her budget. My mom has nothing but amazing things to say about Granite World of Colorado and wanted me to leave a review on her behalf. I won't go anywhere else!!!! Granite World ROCKS!!!

This is the worst contractor and countertop experience I have ever had. I have renovated multiple homes in multiple states. If I could give them zero stars I would. I wanted to replace my countertops for two double vanities in a primary bathroom and a large Jack 'n Jill bathroom in my mountain home in Breck. I contracted it through Lowe's in Silverthorne. Granite World confirmed multiple times the install date and window of arrival. When Sergio (installer) arrived to install the countertops instead of using the new faucet templates included in the boxes of the new countertops. He erroneously drilled 4 inch spread holes for an 8" spread faucet and ruined the countertops. I had guests in my home that knew they would be inconvenienced just during the install period and would have working sinks back the next morning in the baths. However, Granite World took the countertops back after I requested them not to so I could have working sinks for my guests. I had to buy 4 " faucets to temporarily install in the countertops. When the faucets arrived I found out that Granite World had taken the countertops. I had to call Daniel at Granite World and beg for them to bring the countertop back so I could have countertops and install the temporary faucets and the first response was "no" sorry "nothing I can do". Then I was called and said that Sergio was coming back with the countertops but that did not happen until 6:30 p.m. Then I was instructed by Daniel to pick out a different countertop than the one I chose so they could refabricate it and get it back out to me. I was told that it was going to come the following Thursday and I made arrangements for someone to be at my house. Then it was moved to Tuesday with a window of 8 a.m. to noon. I confirmed again with Amanda that it is was 8 a.m. to Noon. It was approaching 11 a.m. and no one had shown up or contacted me that they were on the way. Amanda responded saying that the installer (Sergio) went to the wrong location first and now it was going to be 4-4:30 before he would be there. Then 4 p.m. rolls around and still no one is at the house when I was told that Sergio would call me when he was 45 minutes away. I have to email Amanda again to ask an ETA, she told me someone should be calling me. At this point it is well after 4 p.m. Then I call Daniel and he says that Sergio should be calling me and that he was arriving in ten minutes. I said again no one has proactively contacted me and therefore no one is at the house right now. I have to scramble to get my property manager there in 15 minutes. There has been no attempt to make restitution on the two sets of temporary faucets I had to buy. Or to reimburse me for two invoices from the plumber to disconnect and reconnect the plumbing twice because of Granite World's error in drilling the wrong holes for the faucets. There was no pro-active communication, I would have received zero communication if I had not reached out. Finally, they arrived at 4:30 p.m. when they were supposed to be there between 8 a.m. and noon. The installers tracked mud on my new carpet. Totally frustrated and disappointed by the lack of customer service. Will never use them or recommend them.

We recently purchased a new Condo in Highlands Ranch and had Granite World replace our entire kitchen countertops and backsplash with beautiful white Quartz. The entire team was awesome and very professional. From the start to finish, we were kept informed of every step and timeline. They did a fabulous job with the removal of the existing granite countertops, disposal, prepping of the new area and the installation of the new Quartz countertops and backsplash. Their entire team were fantastic to work and communicate with. Their customer service team is also amazing, as they respond quickly to any request and attend to your needs, warranties, maintenance, etc. I highly recommend Granite World for any home improvement projects you have in your home.

we went through Home Depot and they connected us to Granite World. Had a bit of a coordination issue from the start, and some surprising change order costs, but ultimately we decided to work with them and loved the end product. Installers Antonio and Christian were amazing.

We have had a terrible experience with Granite World. We purchased our countertop from Home Depot in Arvada and they contracted Granite World to install out countertops. The installation was sloppy (not leveled) and very soon cracked at the seam causing chipping damage on the slabs where they were joined. Granite World sent a tech to inspect and take pictures of the damage and the tech admitted the installation was poor. He said GW would contact us in a couple of days to arrange fixing the problem. After we called and e-mailed over several days, GW sent us a message saying they were not responsible and couldn't do the repair and that we should file a (fraudulent?) claim with Granite Gold (the insurance we purchased to cover the countertop), We contacted Home Depot and they are working to resolve the issue but that effort seems to have stalled. Beware of Granite World and avoid purchasing countertops at Home Depot of Arvada.

I was worried about going though a big-box store for my new kitchen counters and didn't even know who the contractor would be, but the price was right. Luckily the staff from Granite World reached out almost immediately and from start to finish they were friendly, knowledgeable and kept the project on time. The admin staff were easy to work with and great communicators. When i went to view my slabs at their location they made it a pleasurable experience. The measurer and installers were great; punctual, professional, and courteous. In fact they were fun to work with and the project turned out excellent. I couldn't be happier with the results. Would highly recommend Granite World for your next project!

We are SO pleased with the professionalism and kindness we received from the entire staff at Granite World! From sales, accounting, measuring, demo and install...every employee was extremely helpful, kind and more than courteous! They removed granite from a backsplash and made it into a new counter area of our kitchen! They made a windowsill for us and a new island countertop! They were extremely prompt on responses and install. I even visited the shop twice and received the same hospitality and helpfulness! Our kitchen looks amazing and their products and design staff are remarkable! Ask for Ashley, but everyone we met there was really awesome to work with!

Poor Craftmanship I had very expensive porcelain fabricated and installed on my fireplace by Granite World of Colorado. During installation they informed me there would be a gap around the fireplace face. What they failed to tell me is that the porcelain was too big, and that they had to hand trim the pieces resulting in multiple chips at the seams. To compound the problem, they didn't use matching glue at the seams which magnified the chips. Wide strips of caulk were used to cover the large gaps at the wall from uneven trimming. My driveway was covered with chips of porcelain due to all the trimming. The chips were so obvious that the seams repair individual stated the seams were "yucky, nasty and a rush job". SOME of the chips were minimized by intensive sanding and matching glue. But the intensive sanding left a 2-inch dulled boarder with rounded seam edges. I made a horrible mistake going with Granite World of Colorado. Extremely poor workmanship that I must look at now for the rest of my life.

Great folks who helped me source terrazzo countertops from Wisconsin from a VERY challenging supplier. Of course supply chain and pandemic related issues caused lengthy delays, and the less than stellar performance of the supplier sales team exacerbated the issues, but Gray and Nelli made sure everything they could do was done to ensure my kitchen was gorgeous. The results are really hard to deny. I'd work with the Granite World team in a heartbeat.

Granite World was so easy to work with. They walked us through the entire process. The crew that installed our quartz was friendly and thorough. They made sure we knew how to care for our new quartz and we're done so fast. Definitely will use them again for future orders.
