About Us

Calframe is a privately owned company offering rough framing services. We build custom and multi-unit residential homes as well as commercial buildings. Our focus is on bringing value to our clients to establish long term relationships with quality contractors.


Framing is one of the most lengthy and difficult phases of construction. It’s labor intensive, expensive and every job presents a unique challenge. It’s important to hire a company who has experience working in this chaos and coming up with solutions to complex problems – because they will happen.

Our process eliminates a lot of headache by fine tuning the plans, communicating with the client on any issues we may run into and any changes that may occur during construction.


Who is Calframe?

Established in 2017, Calframe was founded by Mark Muhn Jr, an experienced carpenter from San Jose, CA with the purpose of building high quality residential and commercial buildings. All of our crew members are specialized framers who are trained the proper methods of construction.  This is a place where everyone is learning a safer, more efficient way of building. Our focus as a company is not just to be great builders, but great people.
