"Jim was very prompt and seemed responsive. He is a nice guy who works hard.  He started the work when he said he would and kept it on schedule in spite of some difficult weather.   His brother worked with him the first few days, but after that he did all of the work himself. 
Unfortunately, the work does not look as professional as I had hoped.  Some of the wood is not cut straight, edges are not smooth, and there are many gaps between boards. 
As the work got toward completion I told him of my concern that the workmanship was not good.  Jim said he would get it all fixed up at the end.  He filled some gaps with wood filler and sanded them, but did not finish due to rain.  The filled and sanded joints still look sloppy.  Unfortunately, these joints are right in front of the kitchen window, where we see them all the time.
Jim said he has a lifetime guarantee on his work and will come back to finish this up.  I hope he will.
Another builder told me that the structural work on the deck is very good, even "overbuilt," which I was glad to hear.

Update: Jim came back and relaid some of the boards on the deck and it looks much better! I would definitely hire him again.

Update:  The second summer after Jim built the deck I stained it myself, so I got a close look at the workmanship. Many boards were split by nailing, decking is not spaced uniformly, and  joints are not well fitted. "

Insulation FAQs, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.
