Writing an update over a year later. The concrete has held up great, with only one small visible crack off in a corner (expected for the size and type of patio). For the price, speed, and flexibility, I'd recommend them to anyone looking to rennovate and improve their property. read more

If you can micromanage well, Carlos will get 80% of the job done, but leave you with 20%. If you have no idea what you're doing expect a 50% job... There is no warranty no matter how much he sells you on it. You might be lucky if he comes back to pressure wash but that's the best to expect for a follow-up visit. He runs a one-man army show, hires a third party crew for the bulk of the work. You'll have to manage his crew tight. read more

Don't choose them if you have sprinkler lines. When the job was done one sprinkler head was broken and when I fixed that one I found two other spots where the underground pipe was broken. Both right near other heads so it's not like the pipe would have been hard to guess. One break might have been an accident, but 3 shows carelessness. I reported the problem and messaged with them for a month trying to let him resolve it. This just delayed things and I ended up spending some hours to fix it myself. read more

I would not recommend this company. Carlos and his co worker have decided that my project is not worth making right. Their employee walked across our newly poured driveway and now they do not want to "own" fixing the shoe prints. One picture is what it looked like originally and then their version of fixing it, which now it looks worse. No Credit to our account, no partial refund nothing. read more

Custom Grey Concrete - footprints after the job was "complete" - Masonry/Concrete Near Me - Denver, Colorado

This is the second time we have used this company, in the past ten years. For this project they did a large driveway, two walkways, and two patios. It was a large job. Carlos is a master of concrete. I trust his judgment and recommendations completely. When I asked questions about the estimate, Carlos made a second trip to our house and went over the plan with me, step-by-step. Carlos and his team finished the job in a day and a half--I was impressed. This is a family-owned, local business, and they are the guys you want to be designing and pouring your concrete. Thanks Carlos! read more

They were fantastic. I sent a request during the week via yelp, and CGC was ready to do a quote on Saturday. They were polite, shook our hands, and even showed up early. They gave us a great quote. I asked when they would be ready to pour, he said Tuesday weather depending. I received a message Sunday night, that they would be ready Monday if I was. Perfect. They showed up the Monday, the crew was quiet and worked hard, they even did firewatch for 3o mins, odd, but they did it. I had dug out a bunch of sod and it was piled on the side of the road, they scooped it up and put it in their trailer without even asking. The pad is perfect, aligned with everything around it, and the job site was left topless. I had asked them to fill in a sidewalk slab, and they did it, no charge. CGC was fantastic to work with, my neighbour grabbed them to pour a size patio pad, and he is happy too. Their work exceeded any city permit requirements. Very happy customer read more

We had a very large concrete project (patio and hardscape area) and contacted several other companies for quotes. Of note was one with 5-star ratings that came out but never provided a quote, another seemed reluctant to take on such a large project. Custom Grey Concrete's quote was significantly lower than others and the time to complete the project was pretty quick. The new concrete looks great and we are very satisfied. If you need good work at a fair price, give Custom Grey Concrete a call. read more

This crew is easy to speak to easy to understand and easy to choose. I had multiple bids for a patio and customer grey answered with the best product and result. Very transparent on pricing and high quality materials. When pouring concrete it is best to have everything lined up and how you want it before you pour and these guys know what they are doing. read more

Custom Grey did a great job replacing 2 driveways, our walkway and the floor of the garage. They work very hard and get the job done. We had weeds coming up from the cracks. The garage floor was uneven. The driveway was cracked and falling apart. They ran the gutter under the walkway and had to be careful where the gas line comes up. My before and after pictures don't do justice because the cement was still wet for the after pictures. They came when they said they would be there. They worked all day and stayed on schedule and the price was right. We are very pleased with the results. Plus they let us have the dog make a paw print in the floor. Definitely would recommend. read more

Carlos at Custom Grey Concrete did an excellent job replacing our driveway and porch. He pointed out that a small section of rocks near the house and porch was causing the driveway to crack and the porch to sink because water was getting in there and going under the driveway and porch. He replaced that section with concrete as shown in the fourth photo. His crew was efficient and quick. His price was the most reasonable of the three quotes we got. We are very happy with the results! read more

We worked with Custom Grey on a pathway around our home. Carlos was able to come out quickly to do the quote, the quote came back the next day, and it was right in line with a few other quotes we received. They were able to work with us to wait until the HOA approved the work and scheduled us very quickly after that. Once they started work, it only took them a fraction of two days, and the work was clean. We were honestly blown away and didn't realize concrete could be so beautiful. Carlos and his team knew exactly what we wanted and we hardly had to weigh in. Maria at the office is also very sweet and patient. We eventually may want to put in a back concrete patio - if we go that route, Carlos will be our first call. read more

I reached out after finding CGC on Yelp. Carlos was very friendly over the phone. His dad ended up coming out to do the quote for several steps & sidewalk slab at the front of our house along with a 8'x14' shed slab. Being in commercial construction, I quickly realized that these guys knew what they were doing and wouldn't be cutting corners. They utilized fiberglass reinforcing and doweled rebar into the adjacent foundations for the front steps so they didn't settle. They gave me a quote Wed night and said they had a short job on Thurs and should be able to get everything prepped and ready to pour concrete on Fri. They exceeded that by getting everything done by end of day Thurs. Quality of steps & shed slab are exceptional. I would definitely use them again! read more

We've used Carlos a couple times now, they do awesome work, very fast, would highly recommend!

I wanted to wait at least six months after the job was completed to leave Custom Grey a review. With concrete, things can go wrong months after the job is completed, that is not the case with our driveway, we are very happy with it, we felt that the company was very reasonably priced, and they did the work in just a few days. I recommend this company to all my friends and family who are looking for a concrete contractor. The driveway they poured was over 3600 ft.², he did the whole thing in 2.5 days, in the winter, it's amazing how efficient they worked, I loved watching them. read more

When working with a contractor, I expect three things. One, do the job well and communicate when you'll be doing it. Two, keep the homeowner's workspace clean and free of damage. Three, listen to customer concerns and take them seriously. Custom Grey Concrete failed at each of these. This was our experience: The team's communication was very bad. When it came to scheduling the work, I was always pursuing them because they would never offer a clear time frame. We understand working around rain days, but communicating with customers is a basic courtesy. They would suddenly text or call me multiple times the day they were ready to start with the expectation that we would clear our schedules to suddenly be ready too. They went dark for more than a week at a time, more than once. This team doesn't care about keeping property clean. The day the concrete was being poured I noticed the crew throwing the used forms up against our side fence, splattering concrete on it. I messaged Carlos about this, more than once, but it was never cleaned (photo-1). This was the same day I contacted him about trash in the yard. He called his guys, who returned and only cleaned up a single bottle. We had trash and recycling containers next to the patio, but they would leave trash on the ground. Their crew damaged our home. Since the patio was built on the back of a new garage, we requested a clean workspace at the start. Carlos was great at saying, "Yes of course, we have so much experience, trust me..." but they never taped off or protected the structure. So, concrete splattered up above the patio onto the new structure, which looked awful (photo-2). This felt unacceptable, so I sent him a picture and he later sent guys to pressure wash everything. But - the pressure washer removed or bubbled up paint, did not clean the concrete completely, and now the transition from patio to structure looks worse (photo-3). We will have to repair and repaint this damage ourselves since Carlos did not. The stamp pattern wasn't aligned with the house. We suppose this could be subjective, but we were stunned to see that the basic brick pattern was visually off, angling and veering off to one direction (photo-4). Carlos became frustrated that I brought this up as a concern. He told me it's the stamp and that it's rubber, so it can't be straight. As if these small things weren't already creating a larger disappointment, Carlos began questioning "what I know" about concrete. He would tell me that he's never had an unhappy customer, and he has years of experience. He has so many positive reviews. And, clearly he does. Which is why this was such a bizarre experience for us! With so many small things "off" about the job, everything became noticeable. I called Carlos one final time. I asked him to come out to the job site to look at what we were seeing. Yet again he told me that I don't know what I'm talking about. He told me he was very busy. He became frustrated on the phone. He acted like these issues were our problem. He then said I was "pissing him off" and again reminded me of all of his great reviews and happy customers. He told me that I was complaining about things that don't matter. He started cutting me off mid-sentence and the call went nowhere. He said, "C'mon Chris... it's concrete, it's messy, this is construction. You are pissing me off." The last straw was when someone from his team came out to seal the patio and wrap up the job. After taking a look at the work, there are roller marks and drips down the sides (photo-5) and large chunks of concrete from the original form still remain in the yard, with small areas that didn't get covered with sealant (photo-6/7). I guess we get to clean that up, too? Working with Custom Grey Concrete was a stressful and disappointing two months. We would never recommend this company after our experience. The way the crew handled the project from start to finish, and the way ownership lacked all accountability, is an absolute shame. read more

Overall, I was very happy with the work Carlos did with our driveway. We wanted to expand our driveway, and when receiving quotes for the project, Carlos came in well below the rest. The only thing I might adjust would be the clear sealant I was talked into getting. Carlos said to give the sealant a few months and it won't look patchy. So far, about 2 months later it still is patchy, but I have no reason to not trust Carlos so I will give it a few more months before I adjust my review. read more

Custom Grey Concrete is a highly professional company that replaced my driveway. Carlos' bid was well below any other contractors I contacted and the finished product exceeded expectations. If you have a concrete project, Custom Grey Concrete is the only logical choice. read more

We have used them twice now. The first time, they took out our old wood patio and replaced it with a concrete patio that we wanted. The second time they were out, they regraded the side of our house and laid rock. Both times we have been extremely impressed with the quality of their work, attention to detail and feel they are very reasonably priced. We will definitely be using them for future projects!! read more

Completely unreliable. I set up an appointment with this company ONE week before. The day they were supposed to come they canceled the appointment via yelp message instead of calling. Lack of courtesy since I provided my phone and requested a phone call to provide me with updates. I didn't access yelp and of course I waited for them. Not until later I realized they had used Yelp. They apologized and "set up an appointment" for the next day. I informed them that if the person didn't show up again, i was going to look for a different company. Well...he didn't show up AGAIN during the time THEY scheduled. Not until I contacted them via yelp after the ETA had expired and not hearing from them, they informed me they were running late. Their excuse was "things happen." Sorry but that's not the customer's fault and it's a complete disregard for our time, particularly when it happens TWO days in a row. They really need a reliable time keeper and better customer service. Unfortunately, I wish I had the same experience as others and I didn't have to write this review. However, constructive criticism is always needed to improve a business. read more

Excellent service, I would highly recommend! Great price compared to other local contractors. I was nervous at first because the pictures on yelp only show a dirt cleared area before the "after" picture. Carlos reassured me that they use fiber mesh (metal support that's thinner than rebar), 4000 psi grade concrete, and if the foundation needs a rock base he would include it within the estimate (which he did end up adding). I had a huge project for them, about 750 sqft. Day 1 was the prep work, day 2 was the concreting, and day 3 was to power wash the area. They were very punctual all 3 days and very polite. They cleared away all the old brick and gravel and even worked A LOT on an old tree stump to ensure proper sloping for drainage (I offered to have someone come and grind it lower). I would definitely use them again in the future! read more

Carlos and his team did an amazing job! They showed up on time, and they finished in the time frame they told us it would take. When they left, they left the area very clean. Carlos was very communicative during the whole process. They did did a big patio in our backyard, a walk way and they also extended our drive way a few feet on each side. All of it looks amazing, and all of the staff was very friendly and very respectful. We couldn't be happier!!! I HIGHLY HIGHLY recommend. I will be calling Carlos if i even need concrete work again. read more

I feel like our estimate was rushed that Carlos didn't really find out what it is we wanted one. As a result, I didn't even ask for a quote for the full job as I knew we wouldn't be using this company. It was the lowest bid but it was handed to us on the back of a business card not 5 minutes after Carlos looked at the property. We did get an more precise estimate emailed to us 4 days later but at that point we chose another company to replace our driveway and back patio. read more

Carlos, Carlos Jr and crew were all a pleasure to deal with. Quote came in significantly lower than any other vendor out of at least 7. Fixed my grading issue to protect my foundation and upgraded the look of my very old concrete patios and walkways. They also installed downspouts for my gutters that run under the concrete to flow out in the yard far from the foundation. My gutters aren't standard size and I had some issues after recent heavy rains and they came back out to fix them quickly. Very happy with their work! read more

DO NOT USE THIS COMPANY. This is a complete sham business. I got my patio done thru them and they requested 100% cash for their work. I paid them in cash and they are ridiculous. They would not honor their warranty. The patio that they laid down did not last an year. I have been chasing Carlos but he would keep asking the address and would never return. He has snowballed us for over an year. I'm reporting the same to BBB. I'm taking this to the highest possible level. read more

I was very nervous as this is the first time doing such a big project. Once they got started it was clear they knew what they where doing. I had a million questions and they never hesitated to answer them. I did my driveway garage and they extended and stamped our patio it looks amazing. I would not hesitate to hire them again. read more

Carlos and his crew (all family members) tore out and poured a new 700 sq ft driveway in one day and then the next day sent one of the crew to do a final cleanup including power washing the road in front of the drive. Carlos was very concerned with how the water would run off especially after I mentioned the water would pool under the garage door and into the garage. That no longer occurs with the new driveway. His team worked the concrete to curve down from the high side and the water now runs off the front into the road. Got three bids and Carlos' was the best. Driveway looks great and we have received numerous compliments from the neighbors one who said that it looks so good he was volunteering us to host the annual neighborhood Octoberfest. read more

Carlos and the guys came and replaced our garage, driveway and front and back patio that had cracked away from the house many years ago. They were able to come very quickly to bid the work and to perform the work as well. Left the work site clean and always awesome at communicating what the problem areas were and how he addressed them. They had the whole project completed and cleaned up in no time at all. We are very happy with the new patios, garage and driveway. Thank you! read more

Custom Grey Concrete poured our back patio last year and did such a phenomenal job that we asked them to add to a couple of areas. This is a family business and it shows in all the right ways--they know their job, they listen to your input, and they make it happen. I love how they brushed the concrete two different directions to add texture and interest. They worked around our design of installing a foundation in the middle of the patio and helped us run conduit so we could install a fountain later. They were professional and personable--we highly recommend them!! read more

Custom Grey Concrete is not a company that will provide a warranty worth a dime. We had CGC put in a driveway in late Oct 2018. They poured the first quarter and then ran out of concrete. Second truck didn't arrive for 3-4 hours later. I asked if this would damage the pour and was told this would mix together fine. Looked great after it was poured. In Jan 2020 the concrete started to flake (spalling) and it got worse in Feb. and I called their offices and never heard back from them. I tried to reach them again in early April and was told by Maria that she would ask the owners. Later that day Maria called back, must have been an inconvenience for the owners to call. Maria told me concrete was only covered for 12 months. WOW! Guess I don't want them to pour a foundation. There's a fairly easy fix for them to repair this with a small topcoat and sealer. But, no one cared to look at it or make an effort to fix it. I'm happy to update my post if this is fixed. I also let BBB know about this to see if they can help. My recommendation, if you're looking to hire Custom Grey, is to look for another concrete company/contractor. read more

We recently got our backyard and driveway done by Custom Grey Concrete. We removed most of the grass in the backyard and redid the driveway since it was really cracked. It took only three days for them to complete this project. Juan was a pleasure to work with as well as the rest of the crew. They were all very hardworking, nice, and respectful. Juan was patient with our questions and changes throughout the process. They definitely had the best prices out of all the estimates we received. We are very satisfied with their work and would highly recommend them to anyone. The hardest part about remodeling is finding honest, affordable, and reliable contractors who do great work, but this company fits all of those! read more

LOVE Carlos and the team. We did a walkway from the garage to the back, creating a patio and steps. Love how it turned out. Carlos and the team is nice and friendly. We had no issues. I have emailed him to let him know that we were home if he wanted to come early. I do like they that are flexible. They came at 7 am for 3 days. They don't dilly dally, they get straight to work and they power wash and clean up after themselves. Will definitely recommend them and would use again for our future projects. His pricing are fair and not overly charged like other contractors. Thank you again! read more
