An inspection should explain what was examined, what was inaccessible, what defects were found, and whether further evaluation is needed. Request a written report with photographs and a clear recommendation about use.
Gaithersburg homes: what an inspection should check
Public figures for Gaithersburg as a whole. They describe local housing and heating, not your home, so the visit still starts with your own chimney.
- Median year built
- 1989
- Half of Gaithersburg's housing units were built in 1989 or earlier, so the median Gaithersburg chimney had about 34 years behind it by the 2023 end of the estimates. Frederick, also in Maryland, records 1990, 1 years newer. A chimney of about 1989 has usually been altered or reconnected at least once, which is why the visit starts with what each flue serves today.

- Single-family detached homes
- 19.6%
- 19.6% of Gaithersburg housing units are single-family detached, leaving about 80.4% in some other structure type the same table counts. Hagerstown, also in Maryland, records 33.1%, 13.5 percentage points higher. With 80.4% outside the detached category, one flue can serve more than one home and the roof may not be yours alone, so settle who approves access before the visit is booked.

- Homes heated mainly with utility gas
- 51.2%
- 51.2% of occupied Gaithersburg homes heat primarily with utility gas, so about 48.8% run on oil, electricity, propane or something else. Wood is the primary heat in under 0.1% of them. Heating fuel is not a count of fireplaces, but 51.2% on utility gas shapes what is most likely connected to a Gaithersburg flue.

- Owner-occupied homes
- 51.3%
- 51.3% of occupied Gaithersburg homes are owner-occupied, leaving about 48.7% rented. Frederick, also in Maryland, records 59.2% owner-occupied, 7.9 percentage points higher. The 48.7% that are rented still separate noticing a fault from authorizing the repair, so say which you are when you send the request.
