Construction Company reviews in Denver, Colorado

I’ve worked with Sandstone on several projects over the past year. They conduct themselves with integrity, transparency, and overall good business practices. It is clear that they value their relationships with their clients and subcontractors. I highly recommend them for any project.

Sandstone Construction is dedicated to providing high quality work and customer service. They have extensive knowledge and experience in their field and Scott is always responsive and professional in his communications. I look forward to working with them on all my future remodeling projects!

Sandstone Construction built a garage at our mountain house. We were so happy with the garage that we had them construct a new entry into our mountain house. They are everything you would want in a contracting partner. Both jobs were high quality and beautiful!

Sandstone did a tremendous job on my new 2 1/2 car garage. They were everything you want from a contractor.Outstanding communicators, great quality and timely. They even built a large work bench that wasn't even in the original! I will definitely use them again!

Sandstone is a top notch construction crew and I am super grateful for the amazing work they did on our kitchen remodel. They held their subs accountable and with great professionalism. The project stayed on track and I always knew what was going on because of the level of transparency and communication. It was a great collaboration between them and our design team, making for a pretty smooth remodel, which is tough to do. 100% Recommend!!

Sandstone was incredible! We had a huge 4 month renovation project that they fully managed while we were out of state. The quality of work was second to none, and everyone that entered our home was friendly and professional (at least the ones we met). These guys are honest, fair, and made us feel at ease throughout the whole process.

They helped pick up our mail while we were out of town, moved our lawn furniture inside, and about a million other things that other contractors would never think about doing. They made the entire process as headache-free as possible. We love our home!

Any work we have done in the future will be done by these guys. Plus - our dog loved the Sandstone crew so much, she was sad when the project was over!!

High quality work. Respectful. Efficient and well priced. Honest. Had our deck removed and stairs installed. Really great.

Called them to apply an ask some questions left few messages they don't contact back so idk what to say about this company dont know em

This group does it all. I recommend them for any project, they go above and beyond to ensure the issue is fixed. If they come across another issue, they’ll fix it without hesitation. Thank you! As you already know, you’re on my speed dial.

Excellent experience using CO construction and Demo. Contractor was very responsive through the entire process. Work exceeded expectations, highly recommend.

I have done worked with Ernie with CO Construction on 2 projects, both appeared to managed well and being completed efficiently. Recommended!

Chad and his team renovated our basement and prepped for a kitchen reno to start next spring. I'm an interior designer and have very high expectations. I've recommended them to clients and they haven't let me down. Highly recommend!!!

I scheduled an estimate a week ago for today. I received multiple confirmation emails and even a reminder email of the appointment. The appointment time came and went. After waiting 30 minutes, I called twice and texted the phone number. I did get a call back after a few minutes. He explained to me that the person who was supposed to come and do the estimate called in sick today. No one called me, emailed me, or communicated with me whatsoever regarding this. I moved several meetings to accommodate their 2 hour window for an estimate and they didn't even have the courtesy to call me to let me know that no one was coming. If I didn't call, no one would have reached out to me.

**I want to add to my review now that the company responded. Yes - I did previously schedule an estimate for September 28th. Once I realized I couldn't keep that appointment, I immediately canceled and the company was notified well prior to the appointment time. I then wasn't "rescheduled" as they claim - I made another appointment on my own. I also understand COVID precautions and I'm grateful for them. The company's response to my review makes it seem like they eventually reached out to me about no-showing the estimate. They did not. In fact, an hour before my appointment, I got another confirmation/reminder email from the company confirming the appointment time. I had to call the company twice, left a voicemail, and I needed to send a text before anyone reached out to me. I'll emphasize my last sentence from my review - if I didn't reach out in a variety of ways, they would have never called me. It also appears it is common practice for this company to be late to appointments as evidenced by their instructions in their confirmation email: "Please allow 30 minutes for our estimator to arrive before calling our office." In the future, this company should make it a practice to 1) respect the time of their customers, 2) honor their appointment times and not make it a habit of showing up 30 minutes late or later, 3) follow up with employees when they call in sick to make sure that person's appointments are either covered or canceled, and 4) not make excuses for their mistakes and try to defend themselves with actions they never took like "rescheduling" my appointment or "reaching out to me" or giving me "short notice" - they did none of those things.

CO Construction & Demo did a fantastic job removing an old shower down to the studs and replacing it with a beautiful new tile shower with glass door. All of the work crew were friendly, polite and did a great job. I would not hesitate in using CO Construction & Demo in future remodeling work.

Owner and head contractor Ernie and his team are absolutely amazing! He is on-time, fair with his numbers, they do quality and quick work to get the job done and help their clients get another project going! Highly talented.

Like other reviewers, this too should be a 10-star review instead of only 5. My daughter owns a 115 year old house, 900 square feet, which needed a whole lot of everything. Ernie Vigil and his team of skilled tradesmen came in, gutted it and rebuilt the interior, including: all new plumbing, all new electrical, new HVAC duct work, new stable floor joists, a new load bearing wall beam, new drywall, new floors, paint, baseboard, finishes.
Ernie created a detailed estimate, which was easy to follow and easy to reconcile when weekly invoices came through. We knew exactly what we were paying for. To witness the progress every week was astounding. The hard physical work, the workmanship, the willingness to collaborate and execute, the kindness and respect that everyone we met on the job showed us, created an efficient and exceptional work environment.
The end result was a brand new kitchen, a new bathroom, living room and dining room. The old kitchen became a bedroom. Still only 900 square feet, we have future plans for expansion. No doubt at all that we want Ernie and Co. Const. and Demo to do the work! Thank you Ernie. Thank you Jozette, John, Miguel, Miguel Jr., Marcus, Chris, Greg, Greg, Alfredo, Jeremy, Katie, Baldo, Johnny and others we didn’t get to meet or didn’t catch the name. The house is beautiful!

I called Ernie on a Sunday evening, desperate after a former contractor left me with some work done, for too much money. Ernie's team did more work in a week than I had seen done in months! He is always responsive, reasonable, and certainly knows how to get it done, the right way, the first time.

We had Ernie and his team out to do several projects around our house. The biggest was to rebuild our front deck. They exceeded our expectations in every way. Ernie gave us ideas how to design the new deck (a major upgrade). He let us know step by step what the process would be and sent us over an estimate. When we said we were ready to go, so were they. The team showed up on time and really stuck to the schedule. The finished deck is the envy of our neighbors and we could not be happier. They also rebuilt a side fence for us an shored up a sagging fence in our backyard (both done on time and they look great). We can't wait to work with Ernie and his team again! Thank you so much!

I am so impressed with the owner/operator, Ernie for his professionalism, responsiveness and punctuality! After months of delays, work not being done correctly and being overbudget with a previous GC, Ernie and his crew came in and finished on time, on budget and with high quality craftsmanship! When Ernie states he will have something sent, delivered or completed by a specific day, he delivers on his word.
I highly recommend CO Construction & Demo if you want your project completed on time, on budget and done correctly the first time!!

I was extremely happy and incredibly satisfied with CO Construction & Demo as they opened up and redesigned my kitchen, giving me the room I always wanted. Ernie was an amazing project manager, bringing together a highly skilled crew that was efficient, talented, and conscientious. The whole project was completed in less than two weeks and the price was very reasonable. More importantly, Ernie's customer service was off the charts. You'd be crazy not to hire him.

This was a pleasurable experience from the start of the bid to the punch list! Completed in more than timely manner! Ernie and his crew were professionals the entire project. The communication outstanding responded so quickly. If ever a question or problem attended to immediately and resolved. We have 120 year old house with a deteriorating back porch. Ernie and crew accessed it and rebuilt now beautiful much more than an old porch an actual coffee nook. I would rate 10 if I could. If ever have another project I would definitely hire this company hands down.
