New Castle contractors at a glance

188: that is how many contractor and tradesperson records in our Colorado database carry a New Castle address, enough for 64th place among the state's cities, and electrical licenses are the largest group. Active licenses: 113 of 188 (60%). The statewide rate in our data is 54%.

7 profiles carry a state board discipline flag (6 plumbing, 1 electrical), and 5 of those licenses are still active. A flag can mean anything from a paperwork lapse to a serious finding, so read the board record behind it.

Companies are a minority: 16 active electrical contractor and 20 active plumbing contractor registrations, against 129 individual tradespeople.

Experience runs deep: half of the licensed pros here were first licensed in 2010 or earlier, and 9 active licenses date from before 2000. 13 are new since 2024.
