Winter is when fireplaces and wood stoves get the most use across Portland, Lake Oswego, West Linn, Tigard, Tualatin, Beaverton, Sherwood, and surrounding areas. When the nights get cold, people burn more fires, burn them longer, and rely on them for comfort instead of ambiance.
That’s also when we see the most problems.
Every winter, Metro Chimney PDX responds to calls that start with:
- “My fireplace worked fine last year…”
- “It was just cleaned, but now it’s smoking…”
- “We’re burning wood we got for free should be fine, right?”
Most winter fireplace issues don’t come from broken chimneys.
They come from how wood is burned.
This article breaks down the most common mistakes Portland homeowners make when burning wood in winter and how to avoid problems before they turn into expensive repairs or safety risks.
Mistake #1: Burning Storm Wood or “Free” Wood
After windstorms or heavy rain, it’s common to see downed trees and free firewood offers across Oregon neighborhoods. It feels practical. It feels local. And it feels wasteful not to use it.
But here’s the reality:
Just because wood looks dry doesn’t mean it’s ready to burn.
Storm wood is often:
- Recently fallen
- Full of internal moisture
- Heavy with sap and natural oils
- Not properly seasoned
Burning this type of wood creates thick smoke and incomplete combustion. That smoke carries more unburned material up the chimney, which leads to faster buildup and higher fire risk.
This is one of the biggest reasons homeowners end up needing chimney cleaning in Portland Oregon more often than expected.
What to do instead:
Burn only properly seasoned hardwood that has dried long enough. If you didn’t cut, split, and store it yourself or buy it from a reputable source assume it needs more time.
Mistake #2: Assuming “Dry on the Outside” Means Safe to Burn
Many homeowners judge firewood by touch. If it feels dry on the surface, it gets tossed into the fire.
That’s a problem.
Wood dries from the outside in. A log can feel dry while still holding moisture deep inside. When that moisture heats up, it turns to vapor and escapes as smoke.
More smoke = more buildup
More buildup = more maintenance
More maintenance ignored = higher fire risk
This affects fireplaces and wood stoves equally, which is why wood stove cleaning is just as important as traditional chimney cleaning.
Pro tip:
Split a log and look at the center. If it’s dark, damp, or smells fresh, it’s not ready.
Mistake #3: Burning Small, Cool Fires All Winter
A lot of Portland homeowners burn small fires to “take the edge off” rather than heating the home. It feels efficient and cozy.
Unfortunately, cool fires don’t burn off byproducts effectively.
Low-temperature fires:
- Produce more smoke
- Leave more residue behind
- Reduce draft efficiency
- Increase the chance of blockages
Over time, this creates conditions that increase the need for chimney fire prevention services later in the season.
Burning hot enough doesn’t mean unsafe it means controlled, properly sized fires with the right wood.
Mistake #4: Closing the Damper Too Early
This is a classic winter mistake.
The fire looks out. The room feels warm. The damper gets closed to “save heat.”
But hot embers can continue producing smoke long after flames disappear. Closing the damper too soon traps smoke in the system, pushing it backward and leaving deposits where they don’t belong.
This often leads to:
- Smoke smells
- Draft problems
- Residue buildup on internal surfaces
If you’re unsure how your damper works—or whether it’s fully open during use it’s time to have it checked during a professional chimney sweep in Portland Oregon.
Mistake #5: Ignoring the Smoke Shelf
Most homeowners don’t even know what a smoke shelf is and many chimney companies don’t clean it anymore.
The smoke shelf sits behind the firebox and helps control airflow. Over time, it collects soot, ash, and debris.
When it fills up:
- Draft weakens
- Smoke lingers
- Odors increase
- Performance drops
Metro Chimney PDX still vacuums smoke shelves as part of chimney cleaning because skipping that step causes real winter problems especially during heavy use.
Mistake #6: Burning All Winter Without Mid-Season Maintenance
Winter use isn’t the same as occasional fall fires.
If you burn:
- Daily
- For long hours
- In a wood stove or insert
Then waiting a full year between cleanings may not be enough.
Heavy winter use can justify additional chimney cleaning in Portland Oregon or wood stove cleaning mid-season to maintain safe airflow and performance.
Ignoring that can turn a normal winter into a costly spring repair.
Mistake #7: Assuming No Smoke = No Problem
Some of the most dangerous chimney issues don’t show obvious symptoms.
A fireplace can:
- Draft well
- Light easily
- Look “normal”
While still accumulating material in places you can’t see.
That’s why chimney fire prevention isn’t about waiting for smoke it’s about understanding usage patterns and inspecting regularly.
What Portland Homeowners Should Do Instead
Here’s how to burn wood safely all winter:
- Burn properly seasoned hardwood only
- Avoid storm wood and freshly cut logs
- Let fires burn hot enough to establish draft
- Keep the damper fully open during use
- Learn how your fireplace or stove actually works
- Schedule chimney cleaning based on usage, not just the calendar
- Have wood stoves cleaned just as regularly as fireplaces
- Address smells, smoke, or draft changes immediately
These steps don’t require special equipment just good habits and proper maintenance.

FAQs
Q1: What is the most common mistake Portland homeowners make when burning wood in winter?
The most common mistake is burning unseasoned or storm wood. Even if wood looks dry on the outside, moisture inside the log creates excess smoke, which leads to faster buildup inside the chimney and increases fire risk.
Q2: Is storm or fallen wood safe to burn in a fireplace or wood stove?
In most cases, no. Storm wood usually contains high moisture and natural oils. Burning it produces heavier smoke and contributes to buildup, which is why we often see homeowners needing chimney cleaning in Portland Oregon after winter storms.
Q3: Can burning wood incorrectly increase the risk of a chimney fire?
Yes. Burning wet wood, keeping fires too cool, or closing the damper too early can all increase buildup inside the flue. Over time, that buildup can ignite and cause a chimney fire if not properly managed.
Q4: How often should I schedule chimney cleaning if I burn wood all winter?
If you burn occasionally, annual cleaning may be sufficient. If you burn daily or rely on your fireplace or wood stove for heat, you may need chimney cleaning or wood stove cleaning during the winter season, not just once a year.
Q5: Why does my fireplace smell worse in winter even when it’s not in use?
Winter odors often come from soot and residue collecting in areas like the smoke shelf. When airflow changes, those smells can move back into the home. Proper chimney cleaning that includes smoke shelf vacuuming helps prevent this.
Q6: Does a fireplace that drafts well still need inspection?
Yes. A fireplace can draft normally while still accumulating material in areas you can’t see. That’s why chimney fire prevention relies on inspection and cleaning, not just visible performance.
Q7: Are wood stoves safer than open fireplaces in winter?
Wood stoves are efficient, but they still require regular maintenance. Wood stove cleaning is just as important as chimney cleaning because buildup inside stove pipes and liners can also lead to fire hazards.
Q8: What should I do if I notice smoke coming into the room during winter fires?
Stop using the fireplace and schedule a professional chimney sweep in Portland Oregon. Smoke entering the home can indicate restricted airflow, buildup, or damper issues that should be addressed immediately.
Q9: Can I burn smaller fires all winter to reduce buildup?
Burning very small or cool fires actually increases smoke and residue. Properly sized fires with seasoned wood burn cleaner and help maintain better airflow.
Q10: How does Metro Chimney PDX help homeowners prevent chimney fires?
