Three eras in one small city
Longwood was founded in 1878 (Wikipedia), and its oldest buildings still stand in the Longwood Historic District: about 190 acres near SR 434 and CR 427 with 37 contributing structures, listed on the National Register in October 1990. They include the 1873 Inside-Outside House and the 1885 Bradlee-McIntyre House (City of Longwood).
Most of the city is much younger. In Census estimates for 2020–2024, 10.8% of Longwood homes predate 1970 but 41.9% predate 1980, so roughly three in ten were built during the 1970s. Another quarter (25.7%) date from 2000 or later. The median home was built in 1983, two-thirds of homes are detached (67.5%) and the median home value is $354,300 (Census ACS via Census Reporter).
| Era | Where you’ll find it | Likely fireplace and chimney | Check first |
|---|---|---|---|
| 1870s–1930s | The historic district | Masonry, if an original chimney survives; liners may be missing or replaced | Liner, mortar, crown |
| 1960s–1970s | Established subdivisions across the city | Site-built brick is common; early factory-built units also appear | Flue tiles, damper, flashing |
| 1980s–1990s | Later subdivisions | Factory-built units in framed chases become common | Chase cover, storm collar, panels |
| 2000 and later | Infill and newer neighborhoods | Factory-built wood or gas units, or no fireplace | Chase cover, termination cap |
Brick or factory-built? How to tell in two minutes
| Feature | Site-built masonry | Factory-built (prefab) |
|---|---|---|
| Firebox | Firebrick laid in mortar | Metal box lined with molded refractory panels |
| Rating plate | None | Metal label with maker and model, often behind the lower grille |
| Looking up the flue | Square or rectangular clay tile, or bare masonry | Round metal pipe |
| On the roof | Brick or block with a mortar crown | Framed chase in siding or stucco with a sheet-metal cover |
| Typical repairs | Crown, mortar, flue tiles, flashing | Chase cover, storm collar, panels, chase framing |

Our guide to masonry versus factory-built fireplaces goes deeper. For a brick chimney from the 1970s, the typical work falls under chimney masonry and liner repair. For a framed chase, it falls under prefab chimney and chase repair.
Gas log sets in older fireplaces
About one in ten Longwood households (9.9%) heats primarily with utility gas, close to double the Seminole County share of 5.1% in the same Census estimates. That figure doesn’t count gas fireplaces; it only suggests that natural gas service reaches more Longwood homes than most nearby cities. In practice, a 1970s brick fireplace here may have been converted to gas logs at some point.
Gas smell: leave first, then call
If you smell gas near a fireplace, don’t light anything or operate switches. Leave the house and call the gas utility or 911 from outside. Gas-line work is a separate job from appliance service, and we carry that out too. See what to do if a gas fireplace smells like gas.
A vented gas log set still exhausts through the chimney, so the flue has to be clear and sound. One visit can look at the flue, damper, cap and masonry and include a gas log and burner service. Running a new gas line or extending an old one is quoted separately. If the burner won’t start, our explainer on a gas fireplace that won’t light covers the common causes.
Chimneys in the historic district
The chimneys that remain on Longwood’s oldest buildings were built long before modern flue liners and clearance rules. Anyone thinking of using one should start with an inspection of the full flue. For exterior work such as rebuilding a crown or changing brick or mortar, ask the City of Longwood whether any review applies to your property first; sweeping and inspection don’t change the building’s appearance.
Caps, debris and idle flues
A chimney that sits unused through Florida’s long warm season collects leaves, nests and debris, and an uncapped flue lets in rain. A properly sized chimney cap stops most of that. If chimney swifts are nesting, they’re federally protected under the Migratory Bird Treaty Act, so capping waits until they’ve left for the year (USFWS). An annual inspection shows whether the flue needs sweeping at all.
Where to start with a Longwood chimney, fireplace or vent
The whole city is in the service area, from Sky Lark and Longdale to Danbury Mill and the streets around the historic district. Most visits begin with one of these:
- A fireplace nobody has used in years, common in 1970s houses: start with a chimney inspection in Longwood, which shows whether the flue is lined and clear.
- Regular wood fires through the cool months: local chimney sweeping removes creosote before it builds up. A flue full of nests, soot or a musty smell calls for a deeper chimney cleaning.
- Cracked crowns, open mortar joints or a rusted chase top: chimney repair for Longwood homes covers brick and factory-built systems. When the symptom is a stain after rain, help with a leaking chimney begins by finding the entry point.
- A damper that sticks, a cracked firebox or gas logs that won’t stay lit: see fireplace repair options in Longwood.
- A dryer that needs two cycles: a Longwood dryer vent cleaning clears the duct and checks the outside hood.
Longwood shares borders and housing eras with its neighbors. The same visit types apply to homes in Winter Springs and Altamonte Springs chimneys and vents.
