A wood-burning fireplace asks a little more of you than a gas or electric one — mostly because burning real wood leaves behind ash, soot and a residue called creosote. None of that is a reason to worry; it's just a reason to give the system a quick bit of attention before you start using it for the season. This guide walks through what we generally recommend, what you can check yourself, and where a professional comes in.
As a general note: the guidance below is educational and reflects common industry recommendations. Every chimney is different, so if anything looks off, the safest step is to have it looked at before you burn.

Why Wood-Burning Needs a Little Extra Care Creosote & the Fire-Safety Reason to Keep It Clean A Simple Pre-Winter Checklist Do You Need a Sweep, an Inspection, or Both? When to Bring in a Professional Frequently Asked QuestionsWhy Wood-Burning Needs a Little Extra Care
In Dallas–Fort Worth, a wood-burning fireplace often sits unused for most of the year and then gets used in bursts when a cold front rolls through. During those idle months, a few things can happen: creosote and soot from last season stay in the flue, North Texas storms can affect the crown and cap up top, and an uncapped flue is an easy target for birds, squirrels and debris. A little pre-season attention helps you start winter knowing the system is in good shape.
Creosote & the Fire-Safety Reason to Keep It Clean
Creosote is a dark, tar-like residue that forms inside the flue every time you burn wood. It's normal — but it's also flammable, and fire-safety organizations such as the Chimney Safety Institute of America (CSIA) note that creosote buildup is one of the leading contributors to chimney fires. That's the main reason wood-burning chimneys get more maintenance attention than gas or electric.
The reassuring part: this is manageable. Having the flue inspected once a year, and swept when creosote has built up, helps reduce that risk. It doesn't remove every risk that comes with any open flame in a home, but it's widely considered one of the most effective and low-cost steps a homeowner can take. Think of it as routine upkeep, not an emergency.
A Simple Pre-Winter Checklist
Here's what we generally recommend running through before the first fire. A few of these you can do yourself; the rest are worth leaving to a professional.
Things you can check yourself
- Clear out old ashes and debris from the firebox once it's fully cold.
- Open and close the damper to confirm it moves freely and seals when shut.
- From the ground, look up at the chimney for a cap and spark screen, and for any obvious damage or leaning.
- Look for signs of moisture — staining on the wall or ceiling near the fireplace can point to a leak.
- Keep the area around the hearth clear of anything flammable.
Things best left to a professional
- Inspecting and, when needed, sweeping the flue — this is the part that reduces creosote-related risk.
- Checking the crown, cap, flashing and liner for wear or damage.
- Clearing any animal nesting or blockage safely.
- Assessing anything that looks cracked, loose or water-damaged.
Do You Need a Sweep, an Inspection, or Both?
This is the most common question, and the answer depends on your situation:
- An inspection is the right starting point if you just want to know your wood-burning system is ready and you're not sure whether it needs cleaning. Preston's $59 inspection covers that.
- A sweep is the cleaning itself, for when creosote and debris have built up in the flue. If you already know it's due, Preston's $99 sweep includes a free inspection — you can read more on the Chimney & Fireplace page.
- Both often make sense for regular wood burners at the start of the season — check the condition and clear the buildup in one visit.
When to Bring in a Professional
You don't need a problem to book a check — before winter is reason enough. But it's especially worth calling if it's been a year or more since anyone looked at the chimney, if you've noticed smoke drawing poorly or a strong smell, if you see staining that suggests a leak, or if you suspect an animal or blockage. When you're unsure, an inspection is the simplest way to get a clear, honest answer.
