They essentially ruined a Reno I have been waiting years for and my biggest regret is trying to work w a small business like this instead of just getting the same product at Home Depot or Lowe's, where I would have been protected against the major overages and left without a way to return unused product. They also never told me my original product was discontinued so it was only after I reached out for delivery updates, contractors already demo-ing, did I learn I wasn't getting what I had paid for. What ensued after was a mess and a disappointment and cost me a lot of money. STAY AWAY!!!

I'm unsure if this defect is endemic to the DMV region or the entire USA but people in most stores regardless of cost, service, or product do not treat customers with respect or professionalism.

We met with Luis Figueroa (President of CSM) some back in 2020 to come up with designs for our back…read morepatio. He worked with us, and had some great concepts. We paid him a healthy fee (about 15% above competitor quotes) because we believed in his sales pitch of what he could do. I've never felt like more of a fool. When working up the designs we settled on constructing a patio using a patterned and styled stamped concrete with a fieldstone-lined firepit at the edge to make a beautiful centerpiece to our rural Loudoun home. There were a number of delays and slipped schedules getting started, but we didn't think anything of it (now I know they were indicators of Luis' trademark mismanagement and lack of professionalism). I started to get concerned as I watched the crew fumbling with how to stamp concrete. His crew (including his lead stonemason) stood around scratching their heads a bit as they looked at the stamps, sometimes looking on their phones (I now surmise they were looking up how to do it). In the end, they couldn't get the freshly poured concrete stamped, and instead, graded it flat. Once it was dry, they proceeded to lay a veneer of concrete on top (approximately 1cm thick) and stamp that. If you have any idea how stamped concrete works (as I do now that I've had to learn) and/or can visualize how the bonding would work in this scenario, this is all kinds of wrong, as the thin layer of stamped concrete on top cracks and pops off in high heat or low cold. When Luis came by for his final walkthrough (with his girlfriend of the moment on his arm, in what set the tone for his unprofessionalism the rest of the engagement), he assured us it would settle well and the color (which came out blue) would settle down. Fast forward 6 months: The concrete is cracked, bluer, and the firepit had sprouted seams from where it was losing its foundation to due woefully inadequate footings. At this point I reached out to Luis and my troubles really began. To call him non-responsive would feel too kind. It took several calls and emails before I got him on the phone, and rather than listen and parse my complaints, he unloaded his own woes upon me as he was struggling through labor shortages during COVID. He promised to get me on the schedule in the next month. Two months later, he had not reached out. So, I reached back out to him (again, taking several calls/emails before getting a response). Again, he promised, again, he ghosted. This process repeated for a year. In each instance, rather than listen to my complaints on how poor CMS' workmanship was (my patio continued to crumble), he complained to me about his own professional (and sometimes personal) life. On the 4th or fifth round I grew frustrated, and made an implication of investigating legal action if he couldn't give me at least some kind of commitment--and within hours, he responded back to me with his legal council copied, promising that he is "very well represented and it would not go well for me." A contractor who can produce a Lawyer in minutes, but cannot schedule a competent concrete finishing crew is not the right kind of contractor. Obviously, I didn't engage counsel--as small claims would not be able to reclaim the losses I incurred hiring him to assemble an overcharged pile of rubble in my back yard... It's been 16 months since he last promised he would get back to me. I've long-since given up on the $20k+ I've wasted, and hired another contractor to re-do the work he did. I will add, the new contractor had no trouble finding labor in the same market, and marveled at how shallow the footers for my firepit/patio had been dug and was surprised it had stood up as well as it had (which wasn't saying much). Luis is the least reputable contractor I have ever engaged with. Unprofessional, and devoid of any sense of accountability. He like that friend of a friend who offers to help you with something, comes over, does 60% of it.

I had a very negative experience with CSM.

Sometimes a month or more would pass without him responding to multiple texts/emails. Some of the stonework was measured improperly and needed to be demolished and redone twice. He ended up leaving several parts of the job not done at the end. He blew past his schedule by about a half year only to leave the job unfinished (I have someone else completing it) and me incredibly frustrated. Do not recommend.

I recently purchased several pieces of marble from this store for my fireplace. The service was…read morefriendly and professional with a knowledge sales women (Abby). However the marble itself was not good quality. I could not pick up the pieces myself so I had someone else pick them up. Nearly every piece I purchased had a slight crack and was glued at the exact location of the crack on the back of each piece. When I emailed the sales women about this problem she responded "I remember seeing the marble when it was loaded onto the truck, and it seems that it may have been damaged during transportation. I completely understand your frustration with this situation. Unfortunately, as per our policy, we do not cover damages for pickups once the pieces are taken. However, I want to resolve this issue for you. In order to remake and replace the pieces, there will be a remake fee of $250." The person I had pick up the piece did not have a truck, they used an SUV. Additionally, I do not believe it was damaged during transportation as it was glued on the back where each break appeared. I believe they damaged it during cutting or had a slab with imperfections that they sold me. Please take caution by picking up the marble yourself and examining each piece thoroughly before leaving the store. I will not purchase anymore material from this location as they sold me an inferior product at a premium price.

Emerald Landscaping has been our steady landscaping company at my office for a long time now and we…read morecouldn't be more grateful for their service! What's the most special part that we have seen with the crew that works here is the extra attention to details. I planted bulbs myself and a few other plants that Emerald did not put in over the years at my office. In essence, they could have just pulled out my plants as they don't match the existing shrubs and I'd have no right to complain. However, they did not. After carefully removing all of the mulch, the crew lovingly re-mulched around my bulbs and it could not look any more fantastic. Right now, someone is giving these spring bulbs even extra water and love. I am sure any other commercial landscaping company would have just ripped them out and mulched over it as fast as possible, to get to the next job. The gentlemen that show up here are very polite and professional too. They really go the extra mile and take pride in their work and it shows. Also, super fast snow removal too!

Unfortunately, at the start of summer 2026 it was clear that the drains could not handle heavier summer rains. One of the drains had water gushing out of the cleanup valve (photo). The follow-up communication with Emerald was underwhelming. They declined to help me troubleshoot the issue unless I paid a $98 site visit fee. Instead, they proposed additional work to rectify the issue without acknowledging that the work was not completed correctly in the first place. Their "proposal" is comical- it looks like something my 5 year old would draw (photo). I've since redone the work myself with a drain that is properly sloped. I've also included photos of a leaky downspout they would not acknowledge along with an upgrade I did myself with $50 in parts from Home Depot.
