Glem S.
The Team at AlphaCon did an outstanding job. Open and clear communication through the whole process. Derek answered all my questions and explained the work that was being completed in each phase. The quality of work and the team professionalism was the reason we contracted additional work to include rebuilding our staircase and updating our front entry way. We will not hesitate to work with AlphaCon in the future.

Very well considering we had to deal with tight material supplies and Covid delays. But top quality work with attention to detail
Description of Work
We rebuilt 1/2 of our new home
We contracted with Derek and Alphacon to have our basement finished. We elected to get 5 different estimates and not only did the Alphacon estimate come in a timely and detailed manner compared to the others, the estimate was fair and included all the necessary work at a fair price, especially compared to some of the other estimates (some of which were anywhere from $9,000 to $17,000 higher). As far as the work, I cannot say enough. Derek laid out the process and the timeline of the work and stuck to it every step of the way, even finishing up a few days early. It is refreshing to have a contractor actually do what they say and show up when they are supposed to and provide quality work and do whatever it takes to get the job done. Once friends saw the quality of work that was completed in the given timeframe, they have asked for his contact information and I do believe that Derek and Alphacon will be getting some additional business in the near future because of our basement project.
