A quick Burnsville chimney self-inspection can catch small issues before they become costly repairs. Follow these safe steps to check your older brick chimney, but know exactly when to stop and call a licensed sweep like Obsidian Peak Chimney LLC.
Step 1: Check the Chimney Cap and Crown from the Ground
Stand back and use binoculars if needed. Look for a missing, cracked, or rusted chimney cap—especially important on older Burnsville brick chimneys where birds and debris can clog flues. Next, inspect the crown (the concrete or mortar top) for cracks or spalling. A damaged crown lets water seep into the masonry, causing bricks to crumble and mortar to weaken. If the cap is missing or the crown is cracked, stop here and contact. We serve Burnsville and nearby areas like Savage and Lakeville with expert crown repairs and cap installations.
Step 2: Scan the Brickwork for Cracks, Leaning, or Mortar Loss
Walk around your Burnsville home and look up at the chimney from different angles. Older brick chimneys often show hairline cracks or missing mortar joints—especially near the roofline or where the chimney meets the house. Pay attention to any leaning or bulging, which can signal structural failure. If you see more than a few hairline cracks or any shifting, do not climb on the roof. Instead, call us for a professional inspection. We specialize in masonry repair for Burnsville’s historic and older homes. See our full list of services.
Step 3: Open the Damper and Shine a Flashlight Up the Flue
With the damper fully open, use a bright flashlight to look up the flue from the fireplace or stove. You’re checking for creosote buildup (black, tarry, or flaky deposits), obstructions like bird nests, or white staining (efflorescence) that signals water damage. If you see more than 1/8 inch of creosote or any blockage, stop. Creosote is highly flammable and cleaning it safely requires professional tools and training. Learn more about creosote risks in our guide Burnsville Chimney Fire Prevention: Protecting Older Brick Homes from Creosote and Structural Failure.
Step 4: Inspect the Firebox and Hearth for Damage
Look inside the firebox for cracked bricks, missing mortar, or a damaged firebrick lining. Check the hearth extension for cracks or discoloration—especially important in older Burnsville homes where original hearths may not meet modern safety standards. If you see deep cracks, exposed subfloor, or warped metal components, do not use the fireplace. These issues can allow heat to penetrate combustible materials. Schedule a repair with us before lighting another fire.
Step 5: Look for Stains, Odors, or Rust Near the Chimney
Check walls, ceilings, and the attic near the chimney for water stains, soot streaks, or a musty odor—common in Burnsville’s humid summers and cold winters. Also look for rust on the damper or fireplace doors. These signs often mean a leaky chimney or a failing liner. Water is a chimney’s worst enemy, especially in older masonry. If you detect moisture or rust, call a professional immediately to assess the liner and flashing.
WARNING SIGNS: Stop DIY and Call a Professional Now
If you see leaning chimneys, large cracks in the masonry, missing chimney caps, heavy creosote buildup, rusted dampers, or signs of water damage, stop all DIY work. These are not cosmetic issues—they’re structural or fire hazards. Older Burnsville homes with original brickwork are especially vulnerable. Attempting repairs without proper training can void warranties, violate building codes, or cause injury. For your safety and peace of mind, contact Obsidian Peak Chimney LLC today. We’re licensed, insured, and serve Burnsville and surrounding communities like Apple Valley and Rosemount.

Frequently Asked Questions
Should I climb on my Burnsville roof to inspect the chimney myself?
No. Older Burnsville brick chimneys can be unstable, and wet or mossy roofs are slippery. Use binoculars from the ground to check the cap, crown, and upper masonry. If you need a closer look, call a professional. We offer safe, ladder-based inspections for Burnsville homes.
Is it worth cleaning my chimney between professional sweeps in Burnsville?
Yes, but only if you use the right tools and know how. A fireplace brush and gloves can remove light ash between sweeps, but creosote must be handled by pros. Never use chemicals or power tools without training. See our guide How to Clean Your Chimney Between Professional Sweeps: A Burnsville Homeowner’s Guide for safe DIY tips.
Do I really need a chimney liner in my older Burnsville home?
Yes, especially in older brick chimneys. Unlined or damaged liners allow heat to transfer to combustible materials and accelerate masonry failure. Modern liners protect your home and improve draft. We install durable stainless steel liners and offer free estimates in Burnsville and nearby areas like Lakeville and Savage.
