Comprehensive Level 1, 2, and 3 chimney inspections to identify hazards, structural issues, and code violations — protecting your home and family.
Professional Chimney Inspection Services in Minneapolis
A chimney inspection is the single most important maintenance service you can invest in as a homeowner. Your chimney works as a critical safety system, channeling toxic combustion gases — including deadly carbon monoxide — away from your living space. When that system develops cracks, blockages, or structural failures, the consequences can be catastrophic. At AL Chimney Service Minneapolis, our CSIA-certified chimney inspectors use the latest technology to conduct thorough, honest inspections that give you a complete picture of your chimney's condition.
We follow the NFPA 211 standard — the definitive guideline for chimney, fireplace, and venting system inspections — and provide detailed written reports with photographs so you understand exactly what we found and what action, if any, is needed.
The Three Levels of Chimney Inspection
Level 1 Chimney Inspection — Annual Maintenance
A Level 1 inspection is the baseline standard of care for chimneys that are in regular use with no changes to the system, fuel type, or appliance. During a Level 1 inspection, our technician visually examines all accessible portions of the chimney exterior and interior — including the firebox, smoke chamber, damper, accessible flue sections, crown, and exterior masonry. We check for proper clearances, the absence of combustible deposits, and structural soundness. This inspection is recommended annually for all chimney systems and is typically performed alongside a standard chimney cleaning.
Level 2 Chimney Inspection — Recommended for Real Estate Transactions and System Changes
A Level 2 inspection is required when you make changes to your chimney system — such as installing a new appliance, switching fuel types (e.g., gas to wood), or relining the flue. It's also required after any event that may have damaged the chimney: a chimney fire, an earthquake, a severe storm, or a lightning strike. Level 2 inspections include everything in Level 1 plus a video scan of the entire flue interior using a high-resolution chimney camera. This camera inspection reveals hidden cracks, deteriorated mortar joints, liner damage, and obstructions that cannot be seen any other way. We strongly recommend Level 2 inspections for all home real estate transactions.
Level 3 Chimney Inspection — For Serious Damage Investigation
A Level 3 inspection goes beyond what Level 1 and 2 can reveal. It involves removing components of the chimney — such as the chimney crown, portions of masonry, or even building materials surrounding the chimney — to access and evaluate concealed areas. Level 3 inspections are reserved for situations where Level 2 findings suggest significant hazards or structural failures that require deeper investigation. Our technicians handle Level 3 inspections with precision and respect for your home.
Why Chimney Inspections Are Non-Negotiable
Many homeowners assume that if their fireplace seems to work fine, the chimney must be okay. This dangerous assumption has led to thousands of preventable chimney fires and carbon monoxide incidents nationwide. Here's why regular professional inspection is critical:
- Flue liner cracks are invisible without a camera — and they allow heat and flames to contact combustible building materials
- Creosote buildup can reach dangerous levels without being visible from the firebox
- Wildlife nests and debris build up in chimney flues, creating both blockage and fire hazard
- Mortar joints deteriorate from freeze-thaw cycles, allowing water intrusion and eventual structural failure
- Carbon monoxide is odorless and colorless — only an inspection can identify whether your venting system is functioning properly
Our Chimney Inspection Process
Exterior Chimney Assessment
We begin with a thorough visual inspection of your chimney's exterior — examining the chimney crown for cracks and deterioration, the cap for damage or missing components, the flashing for water infiltration points, the masonry for spalling brick and failed mortar joints, and the overall structural integrity of the chimney stack.
Interior Fireplace and Firebox Inspection
Inside your home, we inspect the firebox for cracks in the refractory panels and mortar, the damper for proper seal and operation, the smoke chamber for mortar condition and creosote accumulation, and the smoke shelf for debris.
Flue Video Scanning (Level 2)
Our high-definition camera system is lowered through the entire length of the flue, capturing detailed footage of the liner interior. This reveals cracks, gaps, spalling, deterioration, and obstructions that no amount of visual inspection can catch. You can watch the live footage with our technician and see exactly what we see.
Comprehensive Written Report
Every inspection concludes with a detailed, photo-documented written report. We rate the condition of each component, explain any issues found in plain language, and provide honest, prioritized recommendations. There's never any pressure to purchase services — just clear, accurate information to help you make informed decisions.

Frequently Asked Questions
Everything you need to know
1What is the difference between Level 1, 2, and 3 chimney inspections?
Level 1 is a visual inspection of accessible parts — recommended annually with no changes to the system. Level 2 is required when you make changes (new appliance, different fuel) or after any event (fire, storm, earthquake) and involves video scanning. Level 3 is the most invasive and involves accessing concealed areas by removing components; reserved for serious damage investigation.
2How often should I have my chimney inspected?
The NFPA 211 standard recommends a minimum annual chimney inspection for all chimneys, regardless of use. Even if you only used your fireplace once last season, a yearly inspection ensures no wildlife has built nests, no moisture has damaged masonry, and the flue lining is intact.
3Do I need an inspection before buying a home?
Absolutely yes. A professional chimney inspection before purchasing a home can save you thousands of dollars in unexpected repairs. Chimney issues are commonly missed in standard home inspections. We recommend a Level 2 inspection for all home purchases.
4What do you look for during a chimney inspection?
We inspect the flue liner for cracks, gaps, and deterioration; the masonry for spalling, mortar joint failure, and efflorescence; the crown and cap for damage; the damper for proper operation; the firebox for cracks; and the chimney exterior for water penetration signs. We use video cameras for flue interior imaging.
5How long does a chimney inspection take?
A Level 1 inspection takes approximately 30 to 60 minutes. A Level 2 inspection, which includes video scanning of the flue, typically takes 1 to 1.5 hours. You receive a written report with photos upon completion.
