Chimney Sweeps in Fort Worth: Historic Masonry, Hail and Clay Soil

Fort Worth is slightly drier and a little colder at night than Dallas, and it shares North Texas's hail and severe-storm exposure.

What this means in practice:

• Crowns fail first. Early 1900s chimneys often have a thin mortar "wash" rather than a formed concrete crown. Hail chips it, water gets into the cracks, and freezes open them wider. A crown rebuild with an overhang and drip edge is one of the most common repairs on Fairmount and Arlington Heights houses.
• Clay soils move chimneys. Fort Worth's expansive clays swell in wet springs and shrink in August droughts. A heavy masonry chimney on its own footing can lean away from the wall, crack flue tiles out of sight and open gaps behind the mantel.
• Hail hits every era. Clay chimney pots on bungalows and galvanized chase covers on newer homes both fail after large hail. Texas recorded 902 major hail events (1 inch or larger) in 2025, the most of any state.

Why the "second flue" matters in Fort Worth

Many pre-war Fort Worth houses were built with a masonry flue for a coal stove or gas space heater in addition to the fireplace flue. Later, furnaces and water heaters were often vented into the same masonry chimney. When an old furnace is replaced with a high-efficiency unit that vents through the wall, the gas water heater can be left alone in a flue sized for both. That "orphaned" water heater can produce too little heat to draft properly, so exhaust cools, condenses and can spill carbon monoxide at the draft hood. A sweep should check every flue in the stack, not only the one behind the mantel. See carbon monoxide and chimneys.

Building permits

Fort Worth Development Services issues residential building, mechanical and plumbing permits through the Accela online portal, and its Permit Assist tool lets you scope a residential project to see which permits it needs and their cost. The city has adopted the 2021 International Code Council (ICC) codes, which include the 2021 International Residential Code with its chimney and fireplace chapter and fuel-gas provisions. That is newer than the 2012 IRC baseline set by Texas Local Government Code Section 214.212.

In practice, expect a permit for a wood stove or insert installation, a new prefab fireplace, a chimney liner, a gas line to a fireplace, and a chimney rebuild. Sweeping, inspection, cap replacement and damper repair generally do not need one. Run your project through Permit Assist or ask at the Development Services walk-in counter if you are unsure. Gas piping may require a plumber licensed by the Texas State Board of Plumbing Examiners.

Historic districts and the Certificate of Appropriateness

Fort Worth has 14 locally designated historic districts: Fairmount, Historic Carver Heights, Morningside, Elizabeth Boulevard, Chase Court, Hillcrest, Linden Avenue, Terrell Heights, Stockyards, Mistletoe Heights, Central Handley, Garden of Eden, Kenwood Court and W. A. Powers. Individually designated landmarks outside these districts are also reviewed.

Inside a local district, the city requires a Certificate of Appropriateness (COA) before you apply for building permits for exterior alterations, new construction or demolition. The city lists roofing, siding, windows, porches, additions and foundation work among the items that need COA review, and chimney changes visible from outside fall under the same exterior-alteration rule. Most routine alterations are approved administratively by Historic Preservation staff; new construction, demolition and requests to waive design guidelines go to the Historic and Cultural Landmarks Commission (HCLC), an 11-member volunteer body that meets the second Monday of each month. Districts follow the Secretary of the Interior's Standards and district-specific design guidelines.

General guidance based on the city's published COA scope. Confirm your specific project with Fort Worth Historic Preservation staff before work starts.

National Register listing, such as Fairmount–Southside's 1990 listing, is not the same as local designation. A National Register listing by itself does not restrict a private owner's repairs; the local district designation and its COA rules are what apply. Ryan Place and Berkeley Place, for example, do not appear on the city's list of 14 local districts, although several small nearby districts do. Check your address with the city before assuming either way.

Burn bans and fire safety

Tarrant County Commissioners Court can restrict outdoor burning during drought under Local Government Code Section 352.081, and the Texas A&M Forest Service publishes a statewide burn ban map. County bans target outdoor burning, and the TCEQ's outdoor burning rules do not regulate indoor fireplaces. Texas has no indoor burning curtailment program. If you use a patio fireplace, chiminea or fire pit, read the county order and ask the Fort Worth Fire Department about city fire code limits on recreational fires.

Flue count, roof pitch and matched historic materials drive Fort Worth bills: a two-flue 1920s Fairmount chimney can cost twice as much to inspect and cap as a single-flue prefab.

Book the annual sweep and gas service in September or early October. From November through January, and especially before forecast hard freezes, waits run two to four weeks. Schedule crown and masonry repairs for March through May, after the hail has fallen but before summer heat makes roof work slow, and allow extra weeks if a COA is needed. Leave masonry chimneys alone from late spring through summer if you hear chimney swifts.

Texas has no sweep license. Start with the CSIA "Find a Sweep" locator and the National Chimney Sweep Guild directory, then check reviews and the BBB serving Fort Worth. For older houses, ask: Will you inspect every flue, including water heater and abandoned heater flues? Have you repaired chimneys in Fort Worth historic districts, and will you help with the COA drawings and photos? Do you use mortar matched to soft historic brick? For gas work, ask who holds the plumbing license. Get a certificate of insurance and a written, photo-documented report, and a second quote on any job over about $1,000. See how to hire a chimney sweep.

• Check your district first. Look up your address against the city's 14 local districts before getting repair quotes, so bids include the right materials.
• Test CO near the water heater. Older Fort Worth houses often vent a water heater into masonry. Put a CO alarm near it.
• Watch for gaps after drought. A widening gap between chimney and wall after a dry summer is the early sign of footing movement.

Sweeps serving Fort Worth typically also cover Arlington, Benbrook, Burleson, Crowley, Haltom City, Hurst, Euless, Bedford, North Richland Hills, Keller, Saginaw, White Settlement, River Oaks, Westworth Village, Westover Hills, Aledo and Weatherford.
