KeyCon is simply the best. The quality of their work is extraordinary and their expertise is outstanding. KeyCon helped us after we were recovering from a  fire (caused by a Bosch dishwasher). KeyCon understood everything we needed to do regarding code upgrades and helped us to anticipate and avoid problems. They also helped us prepare all the documents we needed for the insurance company. Their people are great, responsive, talented, and fast.  Our new kitchen is beautiful. KeyCon may be the best company i have ever had the privilege to hire. Go with KeyCon!

The people from Keycon were on time and paid attention to details we thought were important. They did a great job and their people were wonderful. When I asked one of them to return there was no problem.Would give them a 5 of 5.
