Pretty happy with my experience at Irwin Stone. I am doing a little backyard project myself and needed to pick up some paver stones. This place has an overwhelming number of choices and my masonry experience is non-existent. So here I am in the middle of their stone yard, aimlessly looking around when Bub appeared on his forklift and 20 minutes later I was walking out of that place with a pretty good idea of the pattern I was going to use, with all the calculations of how much I need for my project done and a scheduled delivery date! Boom!

I have been to all of the stone yards looking for stone for my house being built. Here at Irwin Stone I found the absolute best customer service they worked with me on pricing and I purchased all of my stone for my house there. As a woman I was treated with the utmost respect! I highly recommend this place!

The good: Quality of product is great and material in the yard is organized nicely and easily accessible. Showroom is nice. Location is conveniently located near the heart of Rockville. The not-so-good: If you are looking for bang for your buck your wallet will not forgive you especially if you need to buy in bulk. Had a much better experience at Tri-State off of Seven Locks.

No frills. A slight bit further but they have a much larger selection of materials. Their prices are amazing too. If you have kids bring them to Tri-State. They will get a kick out of the huge rock quarry -- quite a sight to see.

Very disappointed with Irwin Stone! I went there yesterday to buy gravel. They told me to leave my bag there and come back the next day to pick it up. The next day I came back and the bag was still empty and they were using my palette. Now they told me they didn't fill up the bag because the bag was a competitor bag (Ernest Maier), they also told me that EM have been taking their customers!

This shouldn't be thrown to us, the customers. I went there to buy gravel, not a new bag! I have been working with them since 2010. I just left with no pallet and empty bag Sadly.

I visited Irwin Stone last summer to look at rocks for a garden project. I was glad that they had an office right up front. I went in and got a pricelist, but the sales clerk seemed annoyed that I wasn't a contractor and wasn't helpful. I needed someone to look at my project photos and tell me how much of each kind of stone to buy. They do have clearly-marked numbers on the pallets, and that is very helpful. Prices seemed a bit high. I'd have to do more research on that. I don't need a latte with my purchase. I just want someone to actually talk to me.

Wow great experience. Really fair prices and excellent quality stone. We were doing a french drain and some landscaping and they were extremely helpful. We had a top notch customer service both in person and over the phone.

Irwin's got it all. Unlike some posters here, I've had exceptional service. I have to say.do you want reasonable prices or do you want a latte with your purchase? Hand holding might do well in a European auto showroom.this is a decorative stone business yard. Irwin's website has instructional video clips, lots of named stone sample pictures, delivery information and photos of their trucks. Customers are free to roam the yard. Presumably you can take pictures of stone to compare, what else is needed?

The web has countless sites with detailed construction techniques to view. When I made my Irwin's selection, I paid and it was tagged with my name. The following day when my stone guy came to pick up, he called to tell me, there wasn't enough thick pieces for our project in the bundle I had selected. Irwin service desk made the change and credited me $900, instantly. Had I needed Irwin to deliver they would have for a nominal fee. I like Irwins selection. They can answer questions, but their website is self-illustrative and I can find lots of design ideas on my own, for which I am grateful.

Stone are beautiful but Customer service is nonexistent! Don't waist your time. I found something that I wanted to buy unfortunately the staff was more interested in talking amongst themselves instead of helping customers. They didn't even deserve a star!

Had no problem with customer service at all! Steve was very helpful and took time to answer our questions/make recommendations while servicing a room full of contractors. No pressure to buy, sent us home with a price list and a ton of options. Edit - God help you if you have any issues after you've paid them. Lowered from 5 stars to 1

Building out a patio is a daunting task! But with excellent customer service from Irwin's I got exactly what I needed--even when I made a mistake ordering the wrong sized flagstone. Just ask and they're happy to help! I have a few more projects at home so I'll definitely be coming back to buy all my materials here.

Initially when I was purchasing I felt the customer service was good. I relied on what I thought was expert advise for a home project, giving calculated square footage to the salesman. As it turned out, I was sold double the amount of stone for the job and not enough stone dust to complete the job. Irritated that I had 1.5 pallets of flagstone left, I found an additional use for them since they do not return product purchased.

I missed the call for delivery and came home to another pallet in front of my garage. Upon calling, I was met with a friendly attitude until I got upset that they could not return to move the pallet. The salesman kept talking over me. When I told him to shut up and listen to what I was saying, he hung up on me. I have used this distributor of stone in years past. NEVER AGAIN!

Best customer service and advice! The staff is help at the front desk. It's a little rough knowing how to get help in the field, but once you know you have to get your materials first and then get a ticket before paying at the front desk, everything is perfect.

Great customer service, very helpful staff. Especially Bub. He's friendly and kind and gave us great advice. Recommend!

If you want stone or related items at reasonable prices then this is the place. If you want a beautiful, appealing showroom where a salesperson will eventually rip you off with outrageous prices, then go somewhere else. These guys primarily cater to contractors and masons, so don't expect a showroom experience. Just expect a wide selection and good prices! As long as you have reasonable expectations you will not leave disappointed.

I saw different reviews about Irwin Stone, but was optimistic. Staff is not very helpful. You have to figure things out almost on your own in the yard of stones. You have to be careful with what size you order and check your invoice carefully. They delivered wrong size flag stones and when I called them they almost yelled at me and not being apologetic at all. I would keep away from that place. Sad part is, they don't care at all. Take your business somewhere else so they would care.

My experienced landscaper ordered about 8 yards of 1-3 inch screened river Rock. It came much larger- some 5x8 inches and would never pass thru a 1-3 screen. But by then the stone was on the street and driver gone. Put 1/4 load on my grass. Because stones larger, we came up short on coverage. Both landscaper and I called/spoke to manager. He blamed his wholesaler. Said order was'right'. Passed the blame and never stepped up. Perhaps business too good to care. They seem to be better suited for commercial. Avoid if you're residential customer.

These "guys" are classic.if you want free entertainment from KNOW NOTHING worker bees, go there and laugh. If you want stone, forget it. I called and found out why.the owner is RARELY ever there. AVOID!

Shady business practices, wont give refund or at least offer store credit. Bought some brick that did not match in color to the one we had on our patio they refused to refund money or at least offer store credit.

Irwins has a large selection of flagstone in their inventory with reasonable prices. The folks there are very business-like though and I wouldn't classify as friendly or going out of their way to help us. Just stone guys selling stone to masons and other contractors. So when "civilians" like us walk in our expectations on service are probably just a bit different. That said, I'd still go back for future stone needs and they came highly recommended by our mason.

Had a rock delivered for my front yard. Got a great deal on a big old stone - then had to wait until winter (ground too soft) to get the rock repositioned. The rock was repositioned exactly as I wanted and face the right direction. Will definitely do business with them again if I need stonework or large boulders.

I love this place. It has a HUGE variety of stone, rocks and such and you can't beat the price. Comparably, I have paid 4x as much for gravel at a big box store. They are helpful, friendly and the customer service is impeccable. One Saturday I dropped a large piece of slate on myself while self serving from a pallet. The FOLLOWING Saturday when I went in, the manager, asked me about it.

I guess one of the workers had told them about it and they were concerned. Sure, maybe concerned for liability but genuinely concerned about my wellbeing too. They do lots of business with local landscapers and contractors and self serve individuals too.
