A chimney inspection in Burnsville before winter isn’t optional, it’s how you catch hidden risks like creosote buildup, cracked brickwork, or a failing liner before they cause a chimney fire. For older brick homes, this check should include a camera scope inspection to spot issues inside the flue that a visual exam misses. The Chimney Safety Institute of America recommends an annual inspection, but if you’ve never had one, schedule it now, especially if your chimney hasn’t been swept in over a year or your home is over 50 years old.
What Is a Chimney Inspection (And Why Burnsville’s Older Brick Homes Need One)
During a chimney inspection, we examine the brickwork, liner, and flue for cracks, obstructions, or hidden risks in older homes, before small issues turn into costly repairs. In Burnsville, where many homes date back to the mid-20th century, brick chimneys often hide problems behind their sturdy exteriors, like hairline cracks in mortar or a deteriorating clay liner, that can lead to smoke leaks, carbon monoxide risks, or even chimney fires. Unlike a quick visual sweep, a professional inspection uses tools like a camera scope to examine the flue’s interior, checking for creosote buildup, rust, or gaps in the liner that could let toxic gases into your home.
For Burnsville homeowners, the inspection should focus on three critical areas: the masonry (brick, mortar, and crown), the liner (if your chimney has one), and the flue (the smoke passage). Older brick chimneys, especially those built before the 1980s, often lack modern liners, making them more vulnerable to creosote fires and structural wear. If your chimney is over 30 years old or shows signs of wear, like crumbling mortar or rust stains near the fireplace, schedule an inspection before winter. The National Fire Protection Association (NFPA) reports that chimney fires cause an average of $125 million in property damage annually, and many start from undetected creosote buildup or cracked masonry. /services/ For details, see our service list page.
Step 1: Check the Chimney Crown and Flashing for Winter Damage
The chimney crown, the concrete or mortar cap at the top of your chimney, and the flashing (the metal seal where the chimney meets the roof) are the first lines of defense against water damage. In Burnsville’s wet springs and snowy winters, these areas take a beating. A cracked crown lets rainwater seep into the masonry, weakening brick and mortar over time, while loose or rusted flashing allows water to leak into your home’s attic or walls.
What to look for during your inspection: - Crown cracks: Even small cracks (1/8 inch or wider) can let water penetrate. If the crown is crumbling or missing chunks, it’s past repair and needs replacement. - Flashing gaps: Check the metal flashing around the chimney base and where it meets the roof. If it’s rusted, bent, or pulling away from the roof, it’s failing. - Stains or water marks: Dark streaks on the exterior brick or ceiling near the chimney indicate leaks.
Burnsville-specific tip: If your home is near Lakeville or Savage, where winters bring heavy snow and ice dams, inspect the flashing after the first freeze. Ice dams can force water behind the flashing, accelerating rust and wood rot in your roof decking. A licensed masonry pro can reseal the crown or re-flash the chimney for under $300, but ignoring it can lead to $1,000+ in water damage repairs. /blog/chimney-restoration-burnsville/ We cover this in get in touch for a free estimate page.
Step 2: Inspect the Masonry for Cracks, Spalling, or Mortar Joint Failure
Burnsville’s older brick homes often have chimneys built with sand-lime brick or common brick, which can develop spalling (flaking or peeling) over time due to freeze-thaw cycles. While a single cracked brick might not seem urgent, multiple cracks or mortar joint failure signal deeper structural issues. Water seeps into these cracks, freezes, expands, and eventually weakens the chimney’s integrity.
Red flags to spot during your inspection: - Vertical cracks: Often harmless unless they’re wider than 1/4 inch or extend through multiple bricks. - Stair-step cracks: These indicate shifting or settling of the chimney foundation, a serious issue that may require underpinning. - Mortar joint erosion: If the mortar between bricks is crumbling or missing, the bricks can shift, leading to gaps that let smoke or sparks escape. - Efflorescence: White, powdery deposits on the brick surface mean moisture is migrating through the masonry. While not always dangerous, it’s a sign the chimney isn’t sealing out water properly.
Cost to repair: Minor crack sealing runs $150–$400, while full repointing (replacing mortar joints) can cost $800–$2,500 depending on the chimney’s height and access. If your chimney has spalling bricks, replacing them is cheaper than waiting for a full collapse, especially in Burnsville’s harsh winters. /blog/masonry-repair-burnsville-7-signs-your-chimney-needs-expert/ For details, see the team behind the work.
Step 3: Assess the Chimney Liner (If You Have One)
Not all Burnsville chimneys have liners, many older homes rely on the masonry flue itself to carry smoke. But if your chimney was relined (common in homes built after the 1980s or after a chimney fire), the liner is critical for safety. Liners protect the masonry from heat damage, contain combustion gases, and prevent creosote buildup. A damaged liner can let toxic gases into your home or cause a chimney fire.
How to check your liner during an inspection: - Visual gaps or rust: Shine a flashlight up the flue. Rust stains or visible gaps in a metal liner mean it’s failing. - Cracks or holes: Even small cracks in a clay or ceramic liner can let sparks or smoke into the attic. - Liner sagging: If the liner looks collapsed or uneven, it’s no longer providing a safe passage for smoke.
Burnsville’s older homes often have clay liners, which can degrade over time. If your liner is over 20 years old or shows signs of wear, it may need replacement. A new stainless steel liner costs $1,200–$3,500 installed, but it’s a small price compared to a chimney fire or carbon monoxide poisoning. The EPA’s Burn Wise program the EPA's Burn Wise program recommends inspecting liners annually if you burn wood frequently. /blog/burnsville-chimney-repair-vs-replacement-when-to-fix-vs-repl/ Start with the areas we serve.
Step 4: Look for Creosote Buildup (The #1 Cause of Chimney Fires in Burnsville)
Creosote forms as a sticky, dark buildup when wood doesn’t burn fully, clinging to the inside of masonry chimneys and liners over time. It’s highly flammable and builds up in the flue over time, especially in Burnsville’s older brick chimneys where draft issues are common. The Chimney Safety Institute of America (CSIA) reports that creosote is responsible for 25% of all chimney fires, and Stage 2 or Stage 3 buildup (glazed or tar-like) can ignite with just a spark.
How to spot creosote during an inspection: - Black, sooty residue: Light creosote (Stage 1) looks like dust and is less dangerous. Dark, sticky buildup (Stage 2 or 3) means your chimney needs an urgent sweep. - Glossy or tar-like coating: This is highly flammable and requires professional removal. - Strong, smoky smell: If your fireplace smells like burning tar when lit, creosote is likely burning off.
Burnsville’s wood-burning habits: Many homeowners in Savage or Lakeville use their fireplaces more in winter, accelerating creosote buildup. If you burn softwoods like pine or fir (common in Minnesota), creosote forms faster than with hardwoods. The CSIA recommends sweeping at least once a year for homes that burn wood regularly, but older brick chimneys may need more frequent cleanings. A professional chimney sweep in Burnsville charges $120–$250 for a standard sweep, but skipping it could lead to a $5,000+ chimney fire repair. /blog/burnsville-chimney-problems-solutions-creosote-cracks/ Full details in Chimney Sweep in Savage page.
Step 5: Test the Chimney’s Draft and Smoke Flow
A proper draft pulls smoke up and out of the chimney, but Burnsville’s older brick chimneys often struggle with draft issues due to poorly sealed joints, cracked crowns, or obstructions. A weak draft can cause smoke to spill into the room, carbon monoxide to back up, or creosote to burn off inside the flue instead of exiting safely.
How to test your chimney’s draft: - Light a small fire: If smoke lingers in the room or smells strong, the draft is weak. - Use a draft gauge: A professional will measure the pull in inches per minute. A healthy draft is 10–20 inches per minute for wood-burning fireplaces. - Check for downdrafts: If smoke or sparks shoot out of the top of the chimney on windy days, the flue may be too small or the chimney too tall for your fireplace.
Common causes in Burnsville homes: - Obstructions: Bird nests, debris, or a collapsed liner can block the flue. - Improper sizing: If your chimney is too small for your fireplace, it won’t draw well. - External factors: Nearby trees or a new roof addition can disrupt airflow.
Fixing draft issues: Sealing cracks, installing a chimney cap, or even relining the flue can improve draft. If your chimney is over 30 feet tall, it may need a draft inducer fan ($200–$500) to maintain proper airflow. /blog/chimney-sweep-edina-7-signs-older-brick-home-needs-masonry-p/
Step 6: Schedule a Professional Chimney Sweep in Burnsville
While you can spot some issues with a flashlight and a ladder, a full chimney inspection, especially for older brick homes, requires a licensed professional with a camera scope and NFPA 211 training. In Burnsville, where many chimneys are 50+ years old, hidden problems like internal rust, liner deterioration, or deep creosote buildup often go unnoticed until it’s too late.
What to expect during a professional inspection: - Level 1 Inspection: Visual check of accessible parts (crown, flashing, masonry). Cost: $100–$150. - Level 2 Inspection: Includes a camera scope to examine the flue and liner. Cost: $150–$250. - Level 3 Inspection: Full tear-down (rare, but needed if a fire or major damage is suspected). Cost: $300–$600.
Why hire a Burnsville pro? DIY inspections miss 80% of hidden issues, per the CSIA. A licensed sweep will also check for: - Carbon monoxide risks (from cracked liners or poor draft). - Structural weaknesses (like leaning chimneys or foundation shifts). - Code compliance (Burnsville follows MN building codes, which require annual inspections for wood-burning fireplaces).

Frequently Asked Questions
Should I inspect my Burnsville chimney myself, or hire a pro, especially if it’s an older brick home?
You can do a basic visual check for obvious cracks or creosote, but for older brick chimneys, hire a pro. A licensed inspector uses a camera scope to spot hidden issues like liner damage or deep creosote buildup that a flashlight can’t catch. The Chimney Safety Institute of America warns that DIY inspections miss 80% of critical risks, especially in homes over 30 years old. In Burnsville, where many chimneys lack modern liners, a professional inspection costs $150–$250 but prevents $5,000+ fire repairs.
Is it worth repairing my Burnsville chimney’s cracked crown before winter, or can I wait until spring?
Don’t wait. A cracked crown lets rain and snow melt seep into your chimney, weakening brick and mortar over time. In Burnsville’s freeze-thaw cycles, this accelerates damage, leading to $1,000+ repairs by spring. Sealing a crown costs $150–$300 and takes a few hours. If the crown is crumbling, replacement is $300–$600, cheaper than a full chimney rebuild after water damage. Schedule it now before the first hard freeze.
Do I really need a chimney liner if my Burnsville home’s chimney was built in the 1960s without one?
Yes, if you burn wood regularly. Older brick chimneys lack the heat protection and gas containment of a liner, making them prone to creosote fires, smoke leaks, and carbon monoxide risks. A stainless steel liner costs $1,200–$3,500 but extends your chimney’s life by decades. The EPA’s Burn Wise program the EPA's Burn Wise program recommends liners for homes without them, especially in older brick structures where masonry alone can’t handle modern wood-burning efficiency.
How often should I have my Burnsville chimney inspected if I only use the fireplace a few times a year?
At least once a year, even with light use. Creosote builds up silently, and older brick chimneys develop hidden cracks. The NFPA 211 standard the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) requires annual inspections for wood-burning fireplaces. If your chimney hasn’t been swept in over a year or you’ve had draft issues, schedule a Level 2 inspection (with camera scope) to catch problems early. Burnsville’s wet springs and snowy winters worsen masonry wear, so don’t skip this step.
