Frequently Asked Questions
Here's what homeowners ask us
01
How often should I have my chimney cleaned and inspected?
The National Fire Protection Association (NFPA) recommends an annual inspection for all chimneys, fireplaces, and venting systems. If you use your fireplace regularly — more than a few times a month — an annual cleaning is also recommended. If you haven't had service in several years, start with an inspection so we know exactly what we're working with.
02
What is a Level 1 chimney inspection?
A Level 1 inspection covers all readily accessible portions of the chimney interior and exterior — including the firebox, smoke chamber, flue, and crown. We check for proper clearances, verify structural integrity, and look for obstructions or deposits. A Level 1 is included free with every chimney cleaning we perform.
03
What is creosote and why is it dangerous?
Creosote is a byproduct of burning wood that accumulates on the inside of your flue. It's highly flammable — even a thin layer can ignite and cause a chimney fire that can spread to the rest of your home. Regular cleaning removes creosote buildup before it becomes a hazard.
04
Do I need a chimney inspection before selling my home?
Many buyers and lenders request a chimney inspection as part of the home inspection process — especially for homes with wood-burning fireplaces. A certified inspection report from Nordic Chimney can prevent surprises at closing and give buyers confidence. We work directly with realtors and home inspectors throughout the Twin Cities metro.
05
How do I know if my chimney liner needs to be replaced?
Common signs include visible cracking or deterioration found during an inspection, a chimney that doesn't draft properly, smoke backing up into the room, or a history of chimney fires. Older homes often have clay tile liners that degrade over time. A CSIA inspection will identify liner issues and tell you whether repair or full replacement is the right call.
06
What is tuckpointing and how do I know if I need it?
Tuckpointing is the process of removing deteriorated mortar from chimney joints and replacing it with fresh mortar. You may need it if you see crumbling, cracking, or missing mortar between the bricks. Left untreated in Minnesota's freeze-thaw climate, damaged mortar allows water penetration that can lead to costly structural repairs — or eventually a full rebuild.
07
What's the difference between a chimney crown and a chimney cap?
The crown is the concrete slab that covers the top of the chimney structure, sloping away from the flue to direct water off the chimney. The cap is the metal cover that fits over the flue opening itself, keeping rain, animals, and debris out. Both serve important waterproofing roles — and both can deteriorate over time.
08
Can a clogged dryer vent really cause a fire?
Yes. The U.S. Fire Administration reports that failure to clean dryer vents is the leading cause of dryer fires. Lint is highly flammable, and when it accumulates in the exhaust duct it restricts airflow and can ignite. We recommend annual dryer vent cleaning, especially for ducts longer than 6 feet or those that run through walls or ceilings.
09
How long does a chimney cleaning take?
A standard chimney cleaning and Level 1 inspection typically takes 45 minutes to 1.5 hours, depending on the size of the system and the degree of buildup. We work cleanly and take care to protect your home — floors, furniture, and fireplace surround — during the process.
10
What is a roof-up chimney rebuild?
A roof-up rebuild means we dismantle the chimney above the roofline and rebuild it completely from scratch — new brick, mortar, liner, crown, and cap. It's the right solution when a chimney has deteriorated beyond what repairs can fix. Not every chimney company takes on this level of work. We do.
11
Do you offer same-week scheduling?
We do our best to accommodate your schedule, including same-week appointments when availability allows. Contact us by phone or through our Contact page and we'll find a time that works for you.
12
Are you licensed and insured?
Yes. Nordic Chimney is fully insured and holds CSIA (Chimney Safety Institute of America) certification — the highest professional credential in the chimney industry. We bring that standard of care to every job, regardless of size.
