Hours Monday-Friday: 9:00 pm to 5:00 pm Saturday, Sunday: By appointment only Since our staff is very limited, it is always a good idea to call before coming in.  We do our best to keep the store open during weekly hours, but there is always the chance that an emergency on-site job will require us to temporarily close the shop and work at a customer's site.  Call 414-546-2222 even if we are not in the office and the call will be transferred to one of our technician's cell phones.
