Been in this market since the mid-90s and only sharing my experience. I would never comment on an area or market I have no experience.
Professional Contractors in this area would not even be interested in such a small job - they want the large jobs. They add a PIA Fee.
Three years ago had a 3/1 in Philadelphia went through HD for an estimate bathroom remodel $15k no tile, no gut. Simple. We just sold the property as is.
For the Vent the Contractor was correct to say he wasn't licensed. Although our Contractor would have found someone that was licensed or referred us to someone. The Townships in their area are tough to work with and will pull your license in a second. Often neighbors will report or call the Township to determine if permits were pulled.
We pay top dollar for our Contractor his Labor Cost are high but he finishes the job on time and budget. We have learned the hard way and lost over $250k could be more over the years to unprofessional (I am being kind) contractors.
We have been on a waiting list with our Contractor for a couple of months. We are willing to wait. The best Contractors in this area are booked out until September - some through the end of the year. Good Labor is hard to come by.
Materials are a premium and also Labor is just not the actual work - it includes time to purchase supplies, workman's comp, insurance, fees, etc.
I reviewed the post with my husband before reading your reply and he said that sounds correct.
The Professional Contractors name their price take it or leave it - our Contractor tells us stories how people take the low bid then call him back after a year. Asking him to fix or finish the job he refuses the work.
