When I enter that code at the NAICS link above, it says the following description:
"238990 All Other Specialty Trade Contractors
This industry comprises establishments primarily engaged in specialized trades (except foundation, structure, and building exterior contractors; building equipment contractors; building finishing contractors; and site preparation contractors). The specialty trade work performed includes new work, additions, alterations, maintenance, and repairs."
Then it lists a bunch of businesses as examples, all of which are construction type businesses.
You can use the tool yourself at the link above. Enter the code there in the NAICS top search box on the left side of the screen. The same search box can be used for keywords.
