Chimney Sweeps in Amarillo, Texas: Cold, Wind and Gas Flues on the High Plains

Amarillo's housing is much older than the Texas average and its heating fuel mix is the reverse of the state's: gas first, electricity second.

The Potter County figures on our Texas page tell the same story: 62.3% natural gas and 35.4% electricity. Amarillo straddles Potter County to the north and Randall County to the south, and both matter for burn bans (see below).

NOAA's 1991–2020 climate normals put Amarillo at about 3,872 heating degree days a year, roughly three times Houston's and more than two and a half times Austin's, with about 108 days at or below 32°F and about 17.2 inches of snow. The north Panhandle falls in climate zone 4B (mixed-dry) under the International Energy Conservation Code, the coldest zone in Texas.

How the High Plains climate damages chimneys:

• Freeze-thaw cycling. On a typical Amarillo winter day the temperature crosses freezing twice: below at night, above in the afternoon sun. Water absorbed by a cracked crown, porous brick or open mortar joints freezes, expands and pries the masonry apart. The result is spalling (brick faces popping off), crumbling mortar crowns and loose bricks at the top of the stack. South- and west-facing sides, which thaw every afternoon, often cycle the most.
• Snow and blowing snow. Snow piled against a chimney on the roof melts slowly into the flashing joint and the crown. Windblown snow can pack into an uncapped flue.
• Wind. Strong, persistent wind is a defining feature of the Panhandle. It loosens caps that were only friction-fitted, pulls at flashing, drives rain sideways into masonry and can cause downdrafts that push smoke into the room. It also carries sparks. With dry grass on the edges of the city, a chimney without a spark-arresting screen is a wildfire risk, not just a nuisance.
• Hail. The Panhandle is part of the most hail-prone region of the country. Texas recorded 902 major hail events (one inch or larger) in 2025 according to NOAA data summarized by the Insurance Information Institute, the most of any state. Hail crushes caps, dents chase covers on prefab chimneys and cracks clay chimney pots.
• Deep cold snaps. In February 2021, Winter Storm Uri showed what happens when people push fireplaces and gas appliances hard in an extended freeze. Statewide, at least 300 carbon monoxide poisoning cases and at least 19 CO deaths were reported, many linked to fuel-burning equipment used indoors and vents blocked by ice and snow. In Amarillo, where cold is routine, the parallel risk is a furnace or water heater vent blocked by snow, ice, a nest or a collapsed flue tile.

Amarillo grew fastest after World War II, and its housing decades line up closely with chimney types. The neighborhood notes below are general patterns; ask a sweep to confirm what your house has.

The two-flue post-war chimney

The most characteristic Amarillo chimney is the 1950s brick stack with two flues. One serves the fireplace. The other, often smaller, was built for the gas furnace or water heater. Three things go wrong with the furnace side:

1. Clay tiles crack and collapse. Gas combustion produces water vapor. In a cold masonry flue, that vapor condenses, and the mild acids in it attack mortar joints and tiles. Over decades, pieces fall to the bottom and can block the flue or the furnace connector.
2. The flue becomes oversized. When an old furnace is replaced with a high-efficiency unit, the exhaust is cooler and smaller in volume. In a large, cold masonry flue it may not draft reliably, and condensation increases. The usual fix is a properly sized aluminum or stainless liner, or venting a condensing furnace separately through plastic pipe as its manufacturer specifies.
3. Orphaned water heaters. If the furnace moves to its own vent, a water heater left alone in a large masonry flue can backdraft. Sizing the remaining flue is part of any furnace replacement.

Because these problems can send carbon monoxide into the house, have both flues inspected, not just the fireplace. See carbon monoxide and chimneys and chimney liners.

Building permits: City of Amarillo Building Safety

Inside city limits, building, mechanical and plumbing permits and inspections are handled by the City of Amarillo's Building Safety division. Texas law makes the International Residential Code (IRC) the baseline residential code for cities, and cities can adopt newer editions with local amendments; ask Building Safety which editions it currently enforces before a permitted job. We could not confirm Amarillo's current code editions or permit fee schedule during this update.

As a general pattern (confirm with Building Safety for your job):

• Usually no permit: sweeping, inspection, cap replacement, damper repair, waterproofing, small mortar repairs.
• Usually a permit: installing a wood stove, insert or prefab fireplace; relining a flue; rebuilding a chimney; replacing a gas furnace or water heater (which changes venting); installing a gas insert or direct-vent unit; running gas piping.
• Other trades: gas piping requires a licensed plumber in Texas (check the Texas State Board of Plumbing Examiners license search), and furnace replacement falls under TDLR's air conditioning and refrigeration contractor license (TDLR license search).

After a hailstorm, a roof replacement typically needs its own permit. If the chimney is being reflashed or the chase cover replaced as part of the storm work, make sure the scope and permit cover it.

Burn bans and outdoor burning in Potter and Randall counties

Amarillo sits in two counties. Under Texas Local Government Code Section 352.081, the county judge or commissioners court in each county can prohibit or restrict outdoor burning when drought conditions exist, and Panhandle counties issue bans often during dry, windy periods. Burn bans target outdoor burning; they do not normally prohibit a fire in a code-compliant indoor fireplace or stove. Inside city limits, outdoor burning is further limited by city fire rules and the TCEQ outdoor burning rule; check with the Amarillo Fire Department's fire marshal before burning anything outdoors. For county status, check the Potter County and Randall County websites or the Texas A&M Forest Service statewide burn ban map.

On the High Plains, wind turns a small chimney problem into a big one. Whenever grass is dry and the wind is up:

1. Make sure your cap has an intact spark-arresting screen.
2. Do not burn paper, cardboard or pine needles in the fireplace, which loft burning flakes.
3. Put cooled ashes in a metal can with a tight lid, on concrete, away from fences and the house. Never empty ashes into an alley bin or onto the ground on a windy day.

Carbon monoxide alarms

Texas has no statewide landlord duty to install CO alarms in existing rentals; requirements for new construction come from the building code, and local rules vary. In a city where most homes burn gas and many share chimneys between furnace and fireplace, every home with a gas appliance or fireplace should have CO alarms outside sleeping areas and on each level. Texas landlords must install smoke alarms under Property Code Section 92.255.

Chimney swifts

Chimney swifts nest in masonry chimneys across Texas in the warm months and are federally protected. Texas Parks and Wildlife asks sweeps not to disturb occupied chimneys and to clean after the birds leave in fall.

Amarillo prices are near the middle of Texas ranges for labor, but the job mix is different: more crown, brick and flue liner work, more gas flue inspections, and more cap replacements after wind and hail. Rural calls usually add a travel fee. The ranges below are estimates based on 2026 national surveys (HomeGuide and Angi), adjusted for Panhandle labor and job mix, and consistent with our Texas cost tables. They are not a survey of local companies.

Repair order matters on a freeze-damaged chimney: fix the crown and flashing first (they let the water in), then replace damaged brick, then apply a breathable water repellent. Sealing a chimney that still has a cracked crown traps water inside and makes spalling worse. See chimney leaks and waterproofing and chimney caps, crowns and chase covers.

These are illustrative scenarios built from common Panhandle situations, not real customers. Prices are estimated ranges based on 2026 national surveys adjusted for local labor.

Amarillo's heating season is longer than anywhere else in urban Texas, starting in October and running into April.

• August to September: the best window for the annual sweep and a check of gas furnace and water heater flues before the furnace starts running. Summer is also the easiest time for crown and brick work.
• October to March: peak season. Freezes and snow can delay roof work for days. Heavy wood burners (more than about a cord and a half a year) should plan a mid-season sweep.
• April to June: hail and wind season. Get a post-storm inspection before the roof is replaced. Schedule masonry repairs for warm, dry weather so mortar cures before the first freeze.
• May to September: chimney swift season in masonry chimneys; do not disturb occupied flues.

Texas has no chimney sweep license, and the Panhandle has fewer sweeps than the big metros, so book early and vet carefully:

1. Search the CSIA "Find a Sweep" locator and the National Chimney Sweep Guild directory for Amarillo, Canyon and the wider Panhandle, and read reviews on several platforms. Check the Better Business Bureau serving the Panhandle.
2. Ask for the CSIA certification number and proof of liability insurance and workers' compensation.
3. Ask whether the sweep inspects gas appliance flues and does draft or spillage testing. If a furnace liner is needed, confirm who is licensed to handle the appliance connection.
4. Ask whether the company does its own masonry (crowns, brick) or subcontracts it, and how it handles work in freezing weather.
5. After storms, beware of out-of-town crews selling chimney and roof work door to door. Ask for a local address, references and insurance, and get a second opinion on repairs over about $1,000.

• Secure the cap. Use a cap that screws or clamps to the flue or crown. Friction-fit caps blow off in Panhandle wind.
• Crowns, not coatings. A properly formed concrete crown with a 2-inch overhang and a drip edge outlasts any number of sealer coats on a cracked mortar wash.
• Keep vents clear. After drifting snow, check every exterior gas vent terminal, including furnace and water heater vents.
• Test your draft on cold, calm days. Cold masonry chimneys on the north side of a house can downdraft. Warm the flue with a rolled newspaper before lighting, and crack a window if the house is tight.
• Hail-season photos. Photograph your chimney top each fall. A dated "before" photo helps with the next hail claim.

Sweeps serving Amarillo commonly cover Canyon, Bushland, the town of Panhandle, Hereford, Dumas, Pampa, Borger, Claude, Vega and Happy, and Amarillo areas such as the historic central neighborhoods, the post-war north and east sides, and the newer subdivisions of south and southwest Amarillo.
