Many homeowners in New York wait until the first cold snap to wonder if it’s safe to light their fireplace—but skipping your yearly chimney inspection can hide real risks behind the scenes. Even if everything “looks fine,” creosote buildup, hidden blockages, or small structural issues can turn a cozy night into a safety hazard. Before you start your first fire of the season, here’s what you should know.
Is It Safe to Use My Fireplace If I Haven’t Had an Inspection This Year?

If you’re like most homeowners in New York, the first cold snap hits and suddenly the fireplace becomes the most inviting spot in the house. But it’s also the exact moment many people realize they haven’t scheduled their annual chimney inspection. I hear it every year—someone calls saying, “We only use the fireplace a few times… is it really a big deal?” The short answer? Yes. Chimney systems collect creosote, soot, moisture, and even hidden structural issues long before you see any visible warning signs. And the problem with fireplaces is that the danger doesn’t show itself until it’s too late.
Below is what you need to know before you light a fire this season—and why Certified Chimney Service strongly recommends an inspection before using your fireplace, whether it’s wood-burning, gas, or part of an older chimney system.
Why Annual Chimney Inspections Matter More Than You Think
People assume that if the fireplace looks clean from the front, the whole system is safe. But inspections have nothing to do with “how dirty it looks.” They’re about ensuring the chimney system is structurally sound, ventilating correctly, and free of hidden hazards.
A chimney is exposed to creosote buildup, loose mortar joints, cracked flue tiles, rusted dampers, and hidden water intrusion even when it’s not being used. And in the Northeast—especially around Long Island, Westchester, and NYC—winter moisture, salt air, freeze–thaw cycles, and high winds accelerate that damage.
Most homeowners don’t realize:
- A hairline crack inside the flue can allow heat to reach structural wood.
- Even light creosote can ignite at as low as 451°F.
- Animals often nest in chimneys between spring and fall.
- Gas fireplaces produce invisible issues—corrosion, CO leaks, and draft failures.
This is why the National Fire Protection Association (NFPA-211) states that all fireplaces, regardless of use, must be inspected annually.
The Risks of Using Your Fireplace Without an Inspection
Fireplaces don’t give you warnings. When something goes wrong, it happens fast and silently. Below are the hazards homeowners underestimate the most.
1. Creosote Buildup
Creosote forms every time you burn wood. Even if you burned just a few fires last year, creosote may still be present. And if you used softwoods, unseasoned wood, or burned low-temperature fires, the buildup is even heavier.
Creosote is the #1 cause of chimney fires in the U.S.—over 20,000 per year, according to national estimates.
2. Hidden Blockages
Bird nests, leaves, acorns, deteriorating brick, and even water-damaged mortar can partially or fully block the flue.
A blocked flue means smoke and carbon monoxide can’t escape.
3. Carbon Monoxide Exposure
Without inspection, homeowners have no way of knowing whether the flue is venting properly.
A poorly drafting chimney can push CO into your living space without any visible smoke.
Even gas fireplaces—often thought to be “maintenance-free”—produce carbon monoxide and require inspections just as much as wood-burning systems.
4. Moisture and Masonry Damage
New York homes experience harsh winters. Moisture can:
- seep into mortar joints
- freeze and expand
- crack flue tiles
- rust the damper
- damage the chimney cap
- weaken structural masonry
A small crack becomes a much larger problem by the next season—and inspections catch this early.
5. Structural Failures You Can’t See
Camera inspections often reveal:
- cracked or missing flue tiles
- deteriorated liners
- damaged smoke shelves
- loose bricks behind the fireplace
- separation in the flue joints
These are all dangerous during a fire and invisible from the outside.
What a Professional Chimney Inspection Actually Checks
A proper inspection from Certified Chimney Service examines far more than creosote.
Here’s what our technicians look for—and why it matters before your first fire:
Flue Condition
Is the liner intact? Are tiles cracked? Is there evidence of heat transfer?
A damaged flue is a major fire hazard because flames or heat can reach the home’s framing.
Creosote Levels
Even small amounts can ignite. Our team measures and identifies the type (Stage 1, 2, or 3).
Chimney Cap & Crown
A missing or damaged chimney cap lets rain, snow, and animals enter.
A cracked crown allows water to seep downward—leading to expensive repairs later.
Firebox Condition
Loose bricks, missing mortar, and heat damage inside the firebox compromise safety.
Damper Operation
A damper that won’t open fully or seal properly affects airflow—and increases CO risk.
Smoke Chamber & Shelf
Debris, nesting, or damaged brickwork here can force smoke back into your home.
Exterior Masonry
Spalling, efflorescence, cracks, and water damage are all signs of hidden problems.
Most homeowners are shocked at how much can be wrong even when the fireplace “looks fine.” That’s exactly why inspections exist.
Is It Ever Safe to Use a Fireplace Without an Inspection?
Short answer: No—not in New York, and not under NFPA guidelines.
But here’s a more nuanced version homeowners appreciate:
You might get away with using your fireplace once or twice without an inspection—but you won’t know if you’re taking a risk.
And that’s the point: a chimney can appear safe and still be dangerously unsafe on the inside.
If you recently bought your home, haven’t used the fireplace in years, or aren’t sure when the last inspection was—do not light a fire.
Because:
- Creosote doesn’t disappear.
- Structural cracks don’t fix themselves.
- Animals don’t politely move out when winter arrives.
Your fireplace is a heat-producing appliance inside a wood-framed house.
It deserves respect—and a yearly checkup.
Why Now Is the Best Time to Schedule Your Inspection
Peak chimney season in New York fills up fast. Winter storms, holiday fires, and deep-freeze weeks create heavy demand for chimney services. Scheduling early ensures:
