I do most of the work to get your building for the best price possible. here are some of the things we do in house Excavation, Concrete, wood and metal framing, all structural work. drywall, roofing, painting. after 20 years I have the knowledge of all trades and am proficient in all of them to some degree, but we only use licensed electricians, plumbers and HVAC contractors. We often omit these to get the best pricing. it is best to bid them out when they are ready to be completed, there is not shortage of these trades in the valley.
