Customer Education

It is best to have the fireplace, chimney, stove, or insert inspected before use or even before home sale. A general home inspection is not the same as a hearth system inspection. A pre-listing inspection is the best way to catch issues before they turn into negotiation items.

Possible hidden issues include prior chimney fire, cracked liner, improper appliance connection, missing cap, creosote buildup, damaged panels, unsafe clearances, or venting defects.

What usually solves it: a more detailed inspection, often a Level 2 evaluation, especially when the system history is unknown.

Call Cascade Chimney Service before using a fireplace in a newly purchased home.

Water can enter through a missing cap, cracked crown, damaged chase cover, failed flashing, porous masonry, damaged mortar joints, missing storm collar, or condensation inside the venting system.

Water can rust dampers, damage masonry, stain walls, worsen odor, and accelerate deterioration.

What you can check: rust, white staining, damp odor, dripping, cracked fireplace backwall, loose mortar, or stains near the fireplace.

What usually solves it: chimney cap replacement, crown repair, chase cover replacement, flashing repair, masonry repair, waterproofing where appropriate, or venting correction.

Call Cascade Chimney Service if you see water, rust, staining, or damp odor around the fireplace or chimney.

A smoky smell usually means air is carrying odor from soot, creosote, ash, or moisture back into the home. This can happen because of negative pressure, stack effect, a poor damper seal, moisture intrusion, or a dirty flue.

What you can try first: close the damper, turn off exhaust fans to see if odor improves, check whether the smell worsens during rain or wind, and make sure the chimney has a proper cap.

What usually solves it: chimney cleaning, cap repair, top-sealing damper installation, chase cover repair, moisture correction, or draft/pressure correction.

Call Cascade Chimney Service if fireplace odor keeps returning.

Creosote is combustible residue that forms when wood smoke cools inside the chimney. It may look flaky, sticky, shiny, tar-like, or hard and glazed.

Creosote is dangerous because it can ignite inside the chimney. It also restricts airflow, worsens draft, increases odor, and makes the system harder to operate cleanly.

What you can do: burn dry wood, avoid smoldering fires, keep fires hot enough for clean combustion, and schedule annual inspections.

Call Cascade Chimney Service for creosote evaluation and professional chimney sweeping.

A wood stove that will not stay lit usually has a fuel, air, or draft issue. Fire needs dry fuel, enough oxygen, and a chimney that pulls.

What you can try first: use dry kindling, smaller splits, fully open air controls, a top-down fire, and a slightly cracked nearby window during startup. Avoid packing the stove tightly before draft is established.

What usually solves it: dry wood, better startup technique, chimney cleaning, cap cleaning, gasket repair, or draft evaluation.

Call Cascade Chimney Service if the stove only burns well with a window open or will not stay lit.

Burn dry, seasoned firewood under 20% moisture. Wood should be split, stacked off the ground, covered on top, and stored with airflow around the sides.

Wet wood creates more smoke, more creosote, dirtier glass, weaker heat, and more odor. Avoid treated lumber, painted wood, plywood, particle board, trash, cardboard, glossy paper, plastic, driftwood, and construction scraps.

What you can try first: split a log and test the fresh inside face with a moisture meter.

Call Cascade Chimney Service if your system smokes, smells, or builds creosote quickly even when the wood seems dry.

Black glass usually means the stove is burning too cool or producing too much smoke. Common causes include wet wood, turning the air down too soon, weak draft, dirty chimney, clogged cap screen, worn door gasket, or blocked air wash. Black glass is always caused by poor burn habits or a faulty system and we can help with these.

What you can try first: test wood with a moisture meter, use smaller dry splits, let the stove reach temperature before reducing air, avoid smoky burns, and check that the door gasket seals firmly.

What usually solves it: better fuel, improved burn habits, gasket replacement, chimney cleaning, baffle inspection, cap cleaning, or draft correction.

Call Cascade Chimney Service if the glass turns black quickly after cleaning.

Smoke can spill when the door opens before the chimney draft is strong enough. The solution is to open the stove slowly and let the draft stabilize.

What to do: open the air control fully for 2-5 minutes, let the fire brighten, unlatch the door slightly, pause with the door cracked, then open slowly.

This is often called “burping” the stove. It gives pressure and draft time to settle before the door opens fully.

What usually solves it: better door-opening technique, dry wood, stronger draft, chimney cleaning, or cap cleaning.

Call Cascade Chimney Service if smoke spills every time the door opens.

A clean startup depends on dry fuel, enough air, and a warm flue. Startup smoke often happens because the chimney is cold and the air inside it is heavy.

Try this method: open the damper, crack a nearby window, turn off exhaust fans, place larger splits on the bottom, smaller splits above, kindling and fire starter on top, then light from the top. This top-down method helps heat the flue faster.

If cold air is coming down the chimney, warm the flue first with a lit roll of newspaper near the open damper or warm air directed safely upward.

What usually solves it: dry wood, top-down fire-building, flue preheating, chimney cleaning, or draft correction.

Call Cascade Chimney Service if every fire starts smoky even with dry wood and proper startup.

Smoke entering the room means the fireplace or chimney is not drafting properly. Draft is the movement of smoke and combustion gases up the chimney. When the draft is weak or reversed, smoke takes the easier path into the living space. Atmospheric pressure naturally wants to equalize itself much the same way water does. Cold air is dense while hot air is not.

Common causes include a cold flue, wet wood, blocked cap, dirty chimney, closed damper, negative house pressure, weak chimney height, wind effects, or a fireplace opening that is too large for the flue.

What you can try first: open the damper fully, turn off exhaust fans and dryers, crack a nearby window, use dry kindling, build the fire toward the back, try a top-down fire, and preheat the flue before lighting.

What usually solves it: dry wood, better startup technique, chimney cleaning, cap cleaning, damper repair, draft correction, or flue sizing review.

Call Cascade Chimney Service if smoke continues after basic troubleshooting. Smoking in the home deserves a full system evaluation.
