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.
