Reviews
We had a really great experience with Concretum through Thumbtack. The guys did an awesome job rebuilding our back stairs, and we’re really happy with how they turned out. They worked hard, did a great job, and when they were finished, they cleaned everything up and hauled all the debris away. They left our yard looking really good, which we definitely appreciated! It’s nice to find a company that shows up, does what they say they’re going to do, and takes pride in their work. We would definitely use Concretum again and would recommend them to anyone who needs some work done. Thanks, guys, for a great job!
The guys from Concretum repaired dry rot on our historic exterior staircase. In addition to the carpentry they also sealed and painted the staircase. Great attention to detail, the final product looks fantastic.
Great job replacing and painting damaged door trim
My front steps were falling apart and they fixed them in a day. They even gave me some helpful tips for maintaining them. Would work with again for any home maintenance.
The team repaired my staircase landing and a few loose stairs. They delivered a great improvement of the house and were very pleasant to interact with. I can highly recommend them.
This company was great. Hector helped install a custom light, mount my tv and hang a curtain rail for me. The owner was also nice enough to offer to come by to assist me with something else after hector left.
Victor was extremely friendly and helpful for my project of installing shelves in my shower. He completed the project quickly and was very thorough with the work - even going to the store to get extra materials which were needed to complete the work. Don was very communicative and responsive and was able to setup the work to be completed very quickly with a very fair quote for the price. Will definitely be referring to Concretum again for future projects.
Don is a highly professional contractor—smart and efficient. He brought in the right engineer, Ken, to assess the safety of my existing terrace retaining wall. Ken also helped inquire with the city about whether the wall required a permit. Together, they spent time exploring solutions for the wall.
Concretum Operis did a great job quickly, with excellent communication.
Very pleased with the competent, quality and friendly service. Highly recommended
I reached out on Thumbtack and someone got back to me within a day to get the details of my project. We did an initial walkthrough a few days later and I received a quote within a week. The project was small and not a lot of construction companies take smaller jobs. We needed cabinets cut out and a dishwasher installed, and a custom door for an outdoor shed/office. We ended up adding a garbage disposal install to the project and they were flexible and fair with pricing. Communication was great throughout and I had a text thread with the GC and a project coordinator. The work was done in a reasonable amount of time and we’re happy with how everything turned out. We will definitely work with Concretum on future house projects.
Incredible team to work with for your general contracting needs. Prompt and thorough communication and responses - from providing initial estimates to progress updates throughout the project and milestone completion timelines. Quality work - addressed our needs and incorporated our requests as we discovered new issues along the way, one example being unexpected dry rot in the framing of our garage. Timely in the completion of the work and in coordination with our electrician who was also doing some work. They worked with us on a schedule that was ideal for all parties involved. Will definitely keep this crew in my phone book for my next project. Appreciate you guys!
Very happy with the work provided! They took their time to work with us to build a unique and creative solution to our problem. The existing deck matched perfectly and we plan on using them for future work.
