Plumbing and Radiant heat construction company. Both residental and small commercial. I have one Apprentice that works with me, I usually have no need to hire subcontractor. I hold the following Licenses -Journeyman Plumber #7242JP -Boiler/pressure vessel building service mechanic #5244CL3 -C.C.B. #182772 Licensed in Plumbing and General Contracting I bill out $65.00 per hr. for a Plumber, $25.00 per hr. for a Apprentice and cost plus 20% on material. I will also give hard bids over an estimate if you perfer. Except for remodels, I will only do those on a time and material basis. However, a estimated will be provided before hand. I have been doing this long enough that my estimates are usually pretty close to what the cost ends up being, in fact most of the time I come in under.
