How to Prepare Your Chimney for the First Fire of the Season Safely

The first fire of the season is the one most likely to expose a problem. Fireplaces in Central Texas often sit unused for months, which gives animals, debris, and moisture time to affect a chimney that looked fine last winter. This guide walks through what to inspect, what you can safely check yourself, how to build a first fire correctly, and which warning signs mean you should stop and call a professional before lighting anything.

Key Takeaways

• Inspect first, then light. A chimney that has been idle all summer can hold nests, debris, and creosote.
• Open the damper fully before lighting the fire and keep it open while the fire burns.
• Burn only dry, seasoned firewood, and never burn trash, painted wood, or treated lumber.
• Smoke entering the room is a stop sign, not something to push through.
• Climbing a roof or working inside the flue is a job for a professional.

Start With an Inspection, Not a Match

Creosote forms when the byproducts of burning wood condense on the cooler walls of the flue. The Chimney Safety Institute of America describes it as highly combustible, noting that enough buildup can lead to a chimney fire, and it recommends an annual inspection by a qualified professional, as outlined in its guidance on preventing chimney fires. The NFPA 211 standard, which the institute follows, calls for chimneys, fireplaces, and vents to be inspected at least once a year, whether or not they were used heavily.

A professional chimney inspection looks at the parts you cannot easily see, including the flue interior, the liner, the crown, the damper, and visible masonry. If the inspection finds buildup, chimney sweeping and cleaning removes it before you use the fireplace. Our longer explanation of what a chimney inspection before winter involves covers the process in more depth.

What You Can Safely Check Yourself

You do not need to climb onto the roof to do a useful visual check. From inside the house and from the ground, with a flashlight, you can catch several common problems. Stay off the roof and out of the flue, and stop if anything looks wrong.

If you hear scratching, chirping, or movement inside the chimney, animals are likely present, and a fire should not be lit. Professional chimney nest and animal removal clears the flue safely. A missing or damaged cap is also worth addressing, since chimney caps and spark arrestors help keep animals, debris, and rain out of the flue.

What to Leave to a Professional

Some tasks carry too much risk to attempt without training and equipment. Roof work involves fall hazards, and the inside of a flue cannot be properly evaluated without tools and experience. Repairs to masonry, liners, and crowns should always be done by a qualified professional.

As a general rule, handle the visual checks and fuel preparation yourself, and hand over anything that involves climbing, rods and brushes, structural repair, or gas lines. A fireplace that vents poorly or smokes into the room is covered in our guide on why a fireplace smokes inside the house.

Burn the Right Fuel

What you burn affects both the fire and the chimney. The EPA’s Burn Wise program recommends seasoned wood, which means wood that has dried for at least six months, with a moisture content below 20 percent. Green or wet wood smolders, produces more smoke, and leaves more creosote behind. The agency also advises against burning garbage, plastic, cardboard, painted wood, or pressure-treated lumber, since they can release harmful chemicals. You can review the full recommendations on the EPA’s page about best wood-burning practices.

Store firewood off the ground and covered at the top only, so air can still move around the pile. Wood that has sat uncovered through a wet spell may need extra drying time before it is ready.

How to Build and Light the First Fire

A careful first fire also lets you confirm that the chimney is drawing properly. Follow these steps in order.

• Open the damper fully and confirm it stays open.
• Clear the firebox of old ash and any debris from previous seasons.
• Build a small fire with dry kindling or newspaper and a few seasoned logs, not a large stack.
• Never use gasoline, lighter fluid, or other accelerants.
• Keep the screen or doors in place and keep furniture, rugs, and decorations well clear of the opening.
• Stay in the room while the fire burns, and make sure it is fully out before leaving.

Place cooled ashes in a metal container with a lid and store it outdoors away from the house. Ashes that appear cold can hold hot embers for a long time, so they should never go into a paper bag or a trash bin right away.

Warning Signs During the First Fire

Pay attention to how the fire and the room behave, especially in the first few minutes. The table below lists common signs and sensible responses.

If smoke is a recurring issue, have a professional check the chimney ventilation and draft, because a poorly drawing flue can also let carbon monoxide enter the home.

Carbon Monoxide and Smoke Detectors

Carbon monoxide has no smell, so a working detector is the only reliable way to know it is present. Test the detectors on every level and near sleeping areas before you start using the fireplace, and replace the batteries according to the manufacturer’s instructions. A blocked or damaged flue is one of the conditions that can let combustion gases back into the home, which is a reason an annual inspection matters even if the fireplace has always worked.

Starting the Season in Austin and San Antonio

Central Texas fireplaces tend to see occasional use, often triggered by the first strong cold front. That pattern leaves long stretches of idle time, during which birds and small animals can nest in an open flue and storms can deposit leaves and debris on top. Humid summers can also affect masonry, dampers, and metal components over time.

For those reasons, the first fire is better treated as a planned event, not a spur-of-the-moment decision when temperatures drop. Scheduling an inspection a bit ahead of the cold weather leaves time for any cleaning or repair.

Frequently Asked Questions

Do I need a chimney inspection if I did not use my fireplace last winter?

Yes. A chimney that is not used can still collect debris, nests, and moisture damage, and creosote from earlier seasons may remain in the flue. An annual inspection is recommended whether or not the fireplace was used heavily, and having it checked before the first fire is the safest approach.

Can I check my chimney myself before the first fire?

You can do visual checks, such as testing the damper, looking up the flue with a flashlight, and inspecting the firebox and chimney top from the ground. Do not climb onto the roof or work inside the flue. A professional inspection covers the parts you cannot see.

What kind of wood is safest to burn?

Dry, seasoned wood is the safest choice. The EPA recommends wood that has dried for at least six months with moisture content below 20 percent. Avoid green wood, trash, plastics, painted wood, and pressure-treated lumber, since they produce more smoke and can release harmful substances.

Why does my fireplace smell when I first use it?

A faint smell from dust or dampness can occur after months of disuse, but a strong or acrid odor may point to creosote, debris, or moisture in the flue. If the smell is strong or continues, put the fire out and have the chimney inspected before using it again.
