Source: US Census County Business Patterns ↗Sullivan County, NH had 4 building-exterior services (pressure washing, gutters, pools) with employees in 2019 and 3 in 2023 — little changed. Nationally the count grew 25% over the same years.
What this doesn't tell you: Census counts how many exist each year, not how many opened or closed. A count that barely moves can still hide plenty of churn underneath it. It also can't see solo operators without employees, in any year.
Series runs 2019–2023. Earlier vintages exist but are not comparable: Census changed which small counties it publishes after 2016, so including them would show counties losing an industry that never left.
Census code 561790 is “Other Services to Buildings and Dwellings” — a catch-all for building and dwelling services that have no code of their own. Pressure washing, gutter cleaning, pool service, bin cleaning and holiday lighting all land here, but so do chimney sweeping, duct cleaning and drain cleaning.
The blind spot: This is the coarsest code on the site, and it is a leftovers bucket rather than a category. It cannot tell a gutter cleaner from a pool cleaner from a pressure washer — and it also counts interior trades like chimney sweeps and duct cleaners that none of the businesses here compete with. A county can look well covered on the strength of firms doing work you would never do.
County Business Patterns counts establishments with paid employees. A solo operator with no payroll — the most likely competitor for most of these businesses — is invisible to it, in every county, including this one.
There are more of these per resident here than in the country at large. That is a genuine argument against starting one in Sullivan County without something specific that the 3already operating do not have. It is not fatal — a crowded category can still have a bad-service niche — but “there is room” is not the argument available to you here, and any tool that tells you otherwise is guessing.
Census counts these as one industry, so the 3 above includes all of them together. It cannot tell you how many are any single one.
