Jesse you should think about doing THIS for a living?!?!!
I too used paintable caulk in all crown and trim work...actually had to just go back through and touch up about a month ago....looks good to me!!!
Hey...just a thought....did you clean out that dryer vent???....if it has been used for 10 yrs...it might be pretty nasty/ lint-y?!?!
....I used a vent cleaner and a leaf blower to clean mine.....
Nice work man....how the JOB hunt?
