First Fire of the Season: A North Texas Fireplace Safety Checklist

By the Lowes Chimney Sweep crew · Plano, TX

The first cold snap hits North Texas and the instinct is to light a fire that night. Before you do, it's worth ten minutes and a short checklist — because a chimney that sat unused all spring and summer can hide problems that turn a cozy first fire into a smoky, or genuinely dangerous, evening. Nests, creosote, a blown-off cap, water damage, and dead carbon monoxide alarms are all things that show up on the first burn if nobody checked. Here's a practical safety checklist to run before the first fire of the season in DFW.

1. Get an Inspection Before You Burn

The single most important item, especially if it's been more than a year, is a professional look at the chimney before the season's first fire. A lot can change over months of disuse: an animal may have nested, water may have caused damage, or creosote from last winter is still coating the flue. A chimney inspection catches all of it before you light up, rather than letting you discover a blockage or a cracked liner the hard way with a fire already going. Fall, before the rush, is the ideal time — and the busiest, so book early.

2. Check for Creosote Buildup

Creosote is the flammable residue that builds up in the flue from wood fires, and it's the leading cause of chimney fires. If you burned last winter and haven't had the chimney swept since, there's very likely a layer waiting. You can't reliably judge the amount yourself, which is why it's part of the inspection — but the rule of thumb is simple: if it hasn't been swept since you last burned regularly, have it checked, and have a chimney sweep remove buildup before the first fire. Starting the season with a clean flue is the core of fireplace safety.

3. Look for Nests and Blockages

A chimney that sat idle through spring and summer — peak nesting season in North Texas — is a prime candidate for a bird, squirrel, or raccoon nest, or an accumulation of leaves and debris. A blocked flue can't vent, so your first fire pushes smoke and carbon monoxide back into the room instead of up and out. Before you burn, make sure the flue is confirmed clear. If you've heard scratching or chirping, or you never had a cap, assume something may be up there until it's checked.

4. Inspect the Cap and Damper

Check that your chimney cap is still in place and intact — North Texas storms blow caps off, and a missing one means rain, animals, and debris have had open access all season. If yours is gone, a new cap should go on before you rely on the fireplace. Then test the damper: open it fully and confirm it moves freely and seals properly. A damper rusted or stuck from summer moisture needs attention, because you can't safely burn without being able to open it, and you lose heat if it won't close when the fireplace is cold.

5. Test Your Smoke and Carbon Monoxide Alarms

This one takes two minutes and could save a life. Test every smoke detector and, critically, every carbon monoxide alarm in the home, and replace the batteries. Carbon monoxide is odorless and colorless, and a blocked or malfunctioning chimney is exactly the kind of thing that produces it, so working CO alarms are your last line of defense. If you don't have a CO alarm near the fireplace and sleeping areas, add one before the season starts. This is non-negotiable in any home with a fuel-burning appliance.

6. Burn the Right Wood, the Right Way

Once the system's been checked, set yourself up for clean fires. Burn only well-seasoned, dry hardwood — wood that's been split and dried for at least six months to a year. Wet or green wood smolders, produces far more creosote, and makes weak, smoky fires, which is a bigger issue for the occasional burner. Never burn trash, cardboard, or treated or painted wood, which release harmful chemicals and can spike a chimney fire. Build modest, hot fires rather than huge smoky ones, and make sure the damper is fully open before you light.

7. Clear the Hearth and Have the Basics on Hand

Finally, the simple stuff. Keep the area around the fireplace clear of anything flammable — furniture, rugs, decorations, stockings — by at least a few feet. Use a sturdy screen or glass doors to contain sparks. Keep a working fire extinguisher accessible, and never leave a fire unattended or go to bed with one still burning. These basics don't cost anything and prevent the most common household fireplace accidents. Run through them once at the start of the season and you're set.
