A little prep before your Seattle chimney sweep arrives keeps the visit efficient and may reveal issues early. We’ll show you what’s safe to handle yourself and when to call in the pros.
Clear the area around your fireplace and chimney
Move furniture, rugs, and decor at least 3 feet from the fireplace and hearth. Seattle’s older homes often have tight spaces, so clear a wide path to the chimney entrance. Fold or roll rugs to protect them from soot. If you have a gas fireplace, turn off the pilot light and gas valve before the crew arrives. Remove any stored items from the hearth—Seattle’s damp climate can make stored wood or decorations moldy if left too close to the flue. Learn more about our full list of services.
Check for obvious warning signs before the sweep arrives
Look for white staining on bricks (efflorescence), crumbling mortar, or rust on the damper. These signs often point to water damage, common in Seattle’s older masonry chimneys. If you see soot tracking into your home or a strong campfire smell lingering after use, note it for the technician. Never ignore a chimney that leans or has cracks wider than a credit card—these are emergencies, not DIY fixes. If you spot any of these, pause and call us before the appointment.
Gather your fireplace tools and recent burn records
Collect your fireplace tools, screens, and ash buckets in one spot. If you’ve burned anything other than seasoned hardwood in the past year, write down what it was—Seattle homeowners sometimes burn driftwood or treated lumber by mistake. Keep a log of recent fires, including dates and burn times. This helps the sweep spot patterns in creosote buildup, which is especially thick in homes near Puget Sound’s humid air.
What NOT to DIY—and why it’s dangerous in Seattle
Never climb onto your roof to inspect or clean the chimney—Seattle’s mossy, wet roofs are slippery year-round. Avoid using chemical chimney cleaners or power-washing bricks; these can damage older masonry and void warranties. Do not attempt to repair cracks with caulk or mortar mixes from a hardware store—Seattle’s freeze-thaw cycles will pop them out within a season. These jobs require a licensed sweep to meet local codes and prevent carbon monoxide risks.
When to call Andrew C. Chimney Company instead of waiting
If your chimney hasn’t been serviced in over a year, shows signs of water intrusion, or you’ve noticed smoke backing up into the room, it’s time to call in the pros. Seattle’s older homes often hide hidden damage behind walls or under rooflines—what looks minor on the surface can be a major repair. We offer free estimates and can spot issues like cracked flue liners or deteriorating crowns that DIY prep won’t catch. Contact us today to schedule before the rainy season hits.
After the sweep: what to do next
Ask the technician for a written report on their findings, especially if they flagged cracks, gaps, or liner damage. If your chimney is older than 20 years, consider scheduling a video inspection—Seattle’s historic homes often have hidden flue obstructions. Keep the damper open when not in use to prevent moisture buildup, and store firewood off the ground and covered. If the sweep recommends a repair or liner replacement, request a free estimate to compare options tailored to your home’s masonry.
Frequently Asked Questions
What does white staining on my Seattle brick chimney mean and should I be worried?
White staining (efflorescence) is salt leaching from bricks due to water seepage, common in Seattle’s damp climate. It signals moisture intrusion that can weaken mortar and bricks over time. If you see it, call a pro—it’s a warning sign, not a DIY fix.
Can I burn cedar or driftwood in my Seattle fireplace without damaging the chimney?
Avoid burning cedar or driftwood in Seattle—both produce heavy creosote and corrosive chemicals that damage older masonry and flue liners. Stick to seasoned hardwood like oak or maple to protect your chimney and reduce soot buildup.
How do I know if my Seattle chimney’s leaning is serious or just normal settling?
If your chimney leans more than 2 inches from vertical or has visible cracks wider than a credit card, it’s a structural concern. Seattle’s older homes settle, but a leaning chimney often means foundation or footing issues—stop using it and call us immediately.
