Side note: Do you also think this would have an effect on an individual level? Services such as in-house painting, furniture moving, plumbing work, food delivery etc from outside sources, the fear of contracting a virus could lead more people to take a more Do It Yourself approach and what impact would this have on home delivered services?
There is only so much you can do yourself. Some non-essential work might be postponed but if you have a sewer backing up you will call a plumber.
Anything more complicated like electrical work may need inspection anyway so no big benefit for DIY with regards to virus risk. Stuff that I can do myself and save some money I was already doing before the pandemic. No big change.
