I get asked often to do this ,, base answer to client is 90% of new with a better option to replace, onsite work is costly, moving around with client occupied is clearing the stuff they leave etc. I work hard to turn this stuff down and if i do it at all it is after careful inspection,
who cleans cabinets, moves stuff left by employees, night work, etc
always new doors drawers and counter top,,, if you have meta box drawers you can get the screw on clips and the blum tool for templating the screw locations (works pretty good)
With 8 rooms ask to close two at a time, demo tops and front, have customer remove stuff, plam cabinet edges, install new top and splash then fronts, Keep tight with schedule and you could make money but the most profitable work will be done in the shop not the field, we have a local guy who loves this stuff, got him doing cabinets in two banks while i replace greeter and teller lines, works for me !
Being in Raleigh if you specialized in this and take the lesson of losing money you probably will find far more work than you can handle, contact the building maintenance dept of hotels, hospitals and colleges, give them something to hold like a good flyer, website, ask for an email address and contact them reasonably often, chances are you may just make some money, you can also contact larger millwork companies,, we look at the referral when we don't want it as keeping the customer.
