Although I was helping a colleague on this job (rafter raising), I do contract home addition projects.  I work closely with the Menards contractor desk to build a materials list and make detailed plans.  I would have to sub-contract some portions (i.e. foundation work, electrical, etc.);  however, 90% of the work would be completed by my crew.  Call for a free estimate if you are considering adding on to your home.  419-212-3200
