Ditto. A few weeks ago, I did a house that I scheduled the whole week for. Priced it out so I made as much as I would for an entire week of regular jobs. And it turned out to be a fairly nice week: a few 6 hour days, a 5 hour day, and 9 hours on Friday, 'cause I was lazy early in the week, lol.
The key for me is, not letting the size of it get in your head and mess with you. Chunk it down, and don’t look at the whole job at once.
When I go back to do the job in the fall, I’ll try and get it done in 4 days. All the screens get stored for the winter, so there’s half a day’s work eliminated right there, lol.
It can be awkward if the homeowner is around the entire time, but thankfully this is a vacation home, with the occasional house cleaner or electrician stopping by.
But even with the owners around, it only gets as awkward as you make it. You set the tone. I’ve had 3 and 4 day jobs where the owners were around most of the time, and I just play it cool. They have a ton of windows, it’s up to them whether they choose to hire the one guy who comes highly recommended but takes awhile, or the crew of 3 or 4 that don’t have as stirling a reputation, but may be able to bang it all out in a day.
