I highly recommend Chonko Construction. After contacting about 6 fencing companies for a quote, Greg Chonko stood out as the most professional communicator. His quote was also affordable compared to the other companies. Chonko Construction ended up building us a beautiful fence, during the winter blast and freezing temperatures. Communication was excellent though the entire process.
