You do not need a professional for everything. Some chimney and fireplace upkeep is genuinely DIY-friendly and will make your system safer and cleaner between professional visits. But some jobs — the ones involving your liner, your roof, and combustion safety — are where homeowners get hurt or miss the exact hazard an inspection is meant to catch. Here is the honest line between the two, from the team at Central Chimney Service.

Chimney & Fireplace Care You Can Do Yourself

1. Burn the right wood. Only burn seasoned hardwood that has dried 6–12 months. Wet or green wood creates far more creosote — the tar-like fuel behind chimney fires.
2. Keep the damper working. Open it fully before you light a fire and close it when the fireplace is cold. A stuck or half-open damper wastes heat and can let smoke back in.
3. Clean out cold ashes. Once ashes are completely cold (wait at least 24 hours), scoop them into a metal container. Leave a thin bed of ash in a wood-burning firebox — it helps the next fire.
4. Use a fireplace screen or glass doors. They keep embers off your floor and are the simplest safety upgrade you can make.
5. Watch the outside of your chimney. From the ground, look for crumbling mortar, a cracked crown, missing cap, or white staining. Spotting these early saves you money.
6. Clean your dryer’s lint trap every load, and vacuum behind the dryer. This is the DIY half of dryer-vent safety — it slows the lint that builds up in the vent run.

Jobs That Need a Professional

These are the tasks where DIY goes wrong. Not because you are not capable, but because they involve heights, hidden damage, and combustion safety:

• Sweeping the full flue. Store-bought brushes rarely reach the smoke chamber, and a DIY sweep cannot inspect the liner for the cracks that start fires.
• Any inspection of the liner or masonry. Cracks in a clay liner or crown are often invisible from the ground and need a camera to find.
• Anything on the roof. Cap installation, crown repair, and flashing work are fall risks — leave them to insured professionals with the right gear.
• Relining, repairs, and gas work. These are safety-critical and, done wrong, create fire or carbon-monoxide risk.
• Clearing the full dryer-vent run. The lint packed inside the wall and roof run needs proper brushes and a vacuum to remove safely.

A Simple Rule of Thumb

If a task keeps your fireplace clean and dry from inside the house, it is usually fine to DIY. If it involves climbing on the roof, reaching inside the flue, or judging whether the chimney is safe to use, that is a job for a professional — and it is exactly what an annual sweep and inspection is for.

How Often to Call a Pro

For most Plainfield-area homes, once a year: a professional sweep and inspection before the burning season, plus a dryer-vent cleaning. It is the cheapest insurance you can buy against a house fire.

Frequently Asked Questions

Can I really sweep my own chimney?

You can buy brushes and clear the easy sections, but a DIY sweep misses the smoke chamber and cannot inspect the liner for cracks. Most homeowners miss the exact hazards a sweep is meant to catch.

What wood is best to burn?

Seasoned hardwood — oak, maple, ash — dried 6 to 12 months. Avoid wet, green, or resinous softwoods, which create far more creosote.

How do I know if my chimney is unsafe?

From the ground, watch for crumbling mortar, a cracked crown, a missing cap, water stains inside, or a strong smoky smell. Any of these means it is time for a professional look. See our inspection service.

Is it safe to go on my roof to check the chimney?

We do not recommend it. Roof falls are serious, and most rooftop chimney issues need professional tools and eyes anyway. Check what you can from the ground and call a pro for the rest.

How often should I clean my dryer vent myself?

Clean the lint trap every load and vacuum behind the dryer every few months. The full vent run through the wall and roof should be professionally cleaned about once a year. See our dryer vent cleaning.

Do gas fireplaces need DIY care?

Keep the glass and surround dust-free, but leave the burner, pilot, and venting to a professional. Gas work is safety-critical. See our gas fireplace service.
