Trustworthy, capable, and easy to work with. In an era where competent craftsmen are hard to find, I was pleased to find Mason Koivisto and High Rock Exteriors and Maintenance. Mason was quick to respond, provided a thorough and complete bid, and Calvin did excellent work in completing the project to install flashing to a cedar deck space where it had been overlooked by the original builder. All of this without having to wait weeks for project implementation. I highly recommend you get in touch with Mason for decking and maintenance/upgrading.
