If your Lakewood home’s chimney is cracking, leaking, or showing white stains, it’s likely time for repairs. Ignoring these issues can lead to costly damage, dangerous fumes, or even chimney fires. A licensed Golden chimney sweep can spot hidden problems and recommend the right fix before winter hits.
What a Lakewood chimney inspection looks for
A chimney inspection is a thorough check of your Lakewood home’s flue, liner, bricks, mortar, and flashing to spot cracks, gaps, or buildup that could let heat, smoke, or water inside. The Chimney Safety Institute of America recommends a Level 1 inspection every year for wood-burning fireplaces and stoves. In Lakewood’s older neighborhoods near downtown or along 6th Avenue, many chimneys were built before modern codes and often hide hidden damage behind fresh paint or tuckpointing. A professional will look for spalling bricks, crumbling mortar joints, and signs of moisture damage that a quick walk-by won’t catch. If you’ve recently bought a Lakewood home or haven’t had an inspection in over a year, schedule one before lighting your first fire this fall. Call us for a Lakewood chimney inspection — we’ll give you a clear report and no-pressure quote.
Crumbling mortar joints: The silent Lakewood chimney killer
Mortar joints hold your Lakewood chimney’s bricks together, and they take a beating from Colorado’s freeze-thaw cycles. When water gets into tiny cracks and freezes, it expands and pops out chunks of mortar, leaving gaps that let heat escape and cold air in. In Lakewood’s historic districts or newer subdivisions near Golden Gate Canyon, this problem often starts near the chimney crown or just above the roofline where the flue meets the roof. You might see white streaks or powdery residue on the bricks — that’s efflorescence, a sure sign of moisture damage. Fixing crumbling mortar isn’t just about looks; it prevents smoke leaks and protects your home’s structure. A licensed Golden chimney sweep can tuckpoint the joints with new mortar, matching the original profile to keep your chimney looking right and working safely. Learn about our tuckpointing services
Chimney crown cracks: Why Golden’s summer heat makes them worse
Golden’s high-altitude sun and summer heat can bake your chimney crown until it cracks like a dry lakebed. The crown is the concrete or stone slab that caps the top of your chimney, sealing the flue from rain and debris. When it cracks, water drips straight into the flue, rusting the damper, corroding the liner, and soaking the bricks below. In Lakewood, we see this most often on chimneys that face south or west, where the afternoon sun hits hardest. A cracked crown won’t always leak right away, but once it does, the damage spreads fast. A Golden chimney sweep can patch small cracks with a waterproof sealant or rebuild the crown if it’s beyond repair. Get a free crown inspection before the next storm season hits.
Water stains and white efflorescence: What they really mean
White stains or crusty deposits on your Lakewood chimney aren’t just ugly — they’re a red flag that water is moving through your bricks and mortar. This efflorescence happens when water dissolves minerals in the masonry and deposits them on the surface as it evaporates. In Lakewood, where humidity can spike after summer monsoons, these stains often appear after heavy rain. Left unchecked, water can rot the chimney’s footing, weaken the flue liner, and even seep into your attic or walls. The fix isn’t just scrubbing the bricks; you need to find and seal the leak source, then repair any damaged masonry. A professional chimney sweep will check the flashing, crown, and mortar joints for gaps and recommend the right waterproofing treatment. See our waterproofing options
Loose or missing chimney caps: A Lakewood home’s first line of defense
A chimney cap is a small metal cover that sits on top of your flue, keeping rain, birds, and debris out while letting smoke escape. In Lakewood, where summer hailstorms can dent or dislodge caps, a missing or damaged cap is one of the most common issues we find during inspections. Without a cap, water pours straight into the flue, accelerating rust and cracking in the liner. Birds or squirrels can also nest inside, blocking airflow and creating fire hazards. Installing a new cap costs far less than repairing water damage, and it’s a quick job for a Golden chimney sweep. Look for a cap with a mesh screen to keep embers from escaping and a sturdy spark arrestor to protect your roof. Browse our chimney cap options
Spalling bricks: When your Lakewood chimney bricks are falling apart
Spalling is when the surface of your Lakewood chimney bricks flakes off like old paint, leaving pitted, crumbly faces. This happens when moisture gets trapped inside the bricks and freezes, expanding and breaking the surface. In Lakewood’s older neighborhoods near downtown or along Simms Street, many chimneys were built with softer bricks that are especially prone to spalling. You might notice chunks of brick on the ground or a rough texture on the chimney face. Left alone, spalling bricks can weaken the entire structure and let heat escape, raising your heating bills. The fix is to replace the damaged bricks and repoint the mortar, but first you need to find and stop the water source. A Golden chimney sweep will assess whether the bricks can be salvaged or need full replacement. Request a spalling assessment
Flue liner damage: Why a cracked liner is a Lakewood fire hazard
A chimney flue liner protects your Lakewood home’s walls and framing from heat and smoke. If it cracks or deteriorates, heat can escape into nearby wood or insulation, creating a fire risk. In Lakewood, we often see liner damage in older chimneys that were relined with clay tiles, which can crack under thermal stress or from water exposure. Signs of trouble include soot buildup inside the fireplace, a strong burning smell when not in use, or visible cracks in the liner during an inspection. A damaged liner must be repaired or replaced before you use the fireplace again. Options include relining with a stainless steel liner or installing a new clay tile system, depending on the chimney’s condition and local codes. Compare repair vs. replacement options
Flashing leaks: The sneaky cause of Lakewood attic water damage
Flashing is the metal strip that seals the gap between your Lakewood chimney and roof. Over time, Colorado’s temperature swings can loosen the sealant or bend the flashing, letting water seep into your attic or walls. In Lakewood, we often find flashing leaks after heavy snowmelt or summer storms, especially on chimneys near the roofline or where the flue meets a valley. You might see water stains on the ceiling below the chimney or feel dampness in the attic. Fixing a flashing leak isn’t just about resealing; sometimes the flashing needs to be replaced or the sealant upgraded for better durability. A Golden chimney sweep will check the flashing’s condition and recommend the best repair method. Schedule a flashing inspection

Frequently Asked Questions
Should I repair my Lakewood chimney before winter or wait until spring?
Repair it before winter. Golden’s freeze-thaw cycles can turn small cracks into big problems overnight, and a damaged chimney is a fire hazard when you’re burning wood regularly. If your inspection shows issues, call a local chimney sweep now — we’ll prioritize Lakewood homes before the first cold snap.
Is it worth fixing a Lakewood chimney that’s 50 years old?
It depends on the damage. If the bricks and mortar are sound but the crown or cap is cracked, repairs can extend its life for years. If the flue liner is crumbling or the spalling is severe, replacement may be safer. A Golden chimney sweep can assess whether repair or rebuild is the smarter investment for your Lakewood home.
Do I really need a chimney cap in Lakewood’s dry climate?
Yes. Even in Golden’s semi-arid climate, summer monsoons and hail can damage an uncapped chimney. A cap keeps out water, pests, and embers, preventing costly repairs. In Lakewood, we install caps with spark arrestors to protect your roof and home from stray sparks.
How much does it cost to repair a Lakewood chimney crack?
Repair costs vary widely. A simple crown crack might run $200–$500, while tuckpointing a section of mortar could be $400–$1,200. Spalling brick repairs or flue liner replacement typically start around $1,500 and go up depending on access and materials. Get a free Lakewood chimney repair quote to see what applies to your home.
