A Lakewood chimney repair is urgent if you see cracks in the crown, rusted chase covers, or soot stains on walls. These issues can trap carbon monoxide, spark chimney fires, or fail Denver’s building codes. Fix them before winter, delaying risks $1,500+ in emergency repairs and health hazards. Call a licensed chimney sweep for inspections and repairs that meet NFPA 211 standards.
1. What’s a chimney inspection? (And why Lakewood’s dry climate makes it non-negotiable)
During a chimney inspection, our team examines the flue, liner, crown, and brickwork for cracks, obstructions, or risks that could lead to a fire or gas leak in your home. Lakewood’s dry air and high-elevation winds accelerate wear on brick and mortar, so even minor cracks can let in moisture, pests, or carbon monoxide. The Chimney Safety Institute of America (CSIA) recommends Level 2 inspections, where the sweep removes obstructions and checks inside the flue, before winter, especially if your home is over 20 years old like many in the Belmar or Sunnyside neighborhoods. Schedule a Lakewood chimney inspection to spot issues before they become fire hazards or code violations.
2. Myth: ‘Small cracks in my chimney crown are harmless.’ Fact: They’re a ticking time bomb for Lakewood homes.
The chimney crown, the concrete or brick cap at the top, is your first line of defense against water damage. In Lakewood, where summer hail and winter freeze-thaw cycles are common, even hairline cracks can let in 10+ gallons of water per storm. That water seeps into the masonry, freezes, expands, and cracks the bricks further, weakening the structure. By the time you notice spalling (flaking bricks), the repair cost jumps from $200 for a simple patch to $1,200+ for full crown replacement. If your crown has cracks wider than 1/8 inch or crumbling edges, call a Denver chimney sweep to seal it with a waterproof coating or replace it with a stainless steel crown, which lasts 20+ years and won’t degrade like concrete. Pro tip: Check your crown after hailstorms. Lakewood’s April showers can hide damage until it’s too late.
3. ‘My fireplace smells like gas but I don’t see flames.’ This isn’t normal, and it’s how carbon monoxide starts.
A gas fireplace emitting an odor without burning is a red flag for a cracked heat exchanger or blocked flue. In Lakewood’s older homes (pre-1990s), improperly vented gas fireplaces are a leading cause of carbon monoxide (CO) poisoning. The U.S. Environmental Protection Agency the EPA warns that CO is odorless and deadly, yet many homeowners ignore the smell because they assume it’s just ‘dust.’ If you detect gas smells, turn off the fireplace immediately, open windows, and schedule an emergency chimney inspection. A blocked or corroded flue can cost $300–$800 to clean or reline, but a CO leak could cost a life. Denver’s building codes require gas fireplaces to have annual inspections, so don’t skip yours, especially if your home is near the I-70 corridor, where traffic emissions can worsen indoor air quality.
4. ‘My chimney liner looks rusty inside.’ That’s not rust, it’s creosote, and it’s waiting to ignite.
That sticky black residue lining your chimney isn’t just dirt, it’s creosote, a dangerous, flammable buildup caused by poor combustion in wood-burning appliances. Lakewood’s dry air and older fireplaces (common in homes near the Southglenn neighborhood) create the perfect conditions for stage 2 creosote, which looks like glossy black varnish and can ignite at 1,100°F. The National Fire Protection Association (NFPA) the NFPA reports that creosote causes 25% of chimney fires, often with no visible flames. If your liner has thick, glossy deposits or you’ve had a chimney fire before, you need a professional sweep, now. DIY scraping can damage the liner, costing $1,000–$3,000 to replace. For Lakewood homeowners, the fix is simple: burn only seasoned hardwoods, avoid smoldering fires, and schedule a chimney sweep Denver every 45 days of use. If your liner is already damaged, relining costs $1,500–$3,500 but prevents toxic gas leaks and fire risks.
5. ‘My chimney chase cover is rusted through.’ That’s how water gets into your home, and your insurance won’t cover it.
The chase cover, the metal panel on your roof where the chimney meets the house, is often overlooked until it’s too late. In Lakewood’s wet springs and snowy winters, a rusted chase cover lets water pool on the roof deck, rotting shingles and framing. Homeowners insurance typically won’t cover water damage if the chase cover was neglected, leaving you with $5,000+ in roof repairs. Replace a rusted chase cover with stainless steel (not aluminum) for $150–$400, and seal the flashing with high-temperature silicone. If your cover is missing entirely, that’s a code violation in Denver, a licensed chimney sweep can install a new one and ensure it meets NFPA 211 standards. Pro move: Check your chase cover after ice dams form. Lakewood’s elevation makes them worse.
6. ‘My fireplace drafts poorly.’ That’s not just annoying, it’s how carbon monoxide sneaks into your home.
A weak or reverse draft isn’t just about cold air rushing in, it’s a sign your flue is blocked, cracked, or improperly sized. In Lakewood’s older homes, chimneys built for coal or wood may not vent gas fireplaces efficiently, creating negative pressure that pulls CO into the living space. Test your draft by holding a lit match near the fireplace opening: if the flame flickers outward, your flue is blocked. If it pulls inward, your chimney isn’t drawing properly. Both are emergencies. A blocked flue costs $200–$600 to clear, while a resized or relined chimney runs $1,200–$4,000. Don’t wait, book a chimney sweep near me before your CO detector goes off.
7. ‘My chimney bricks are crumbling.’ That’s not wear, it’s mortar failure, and it’s a fire hazard.
Spalling bricks or crumbling mortar aren’t just cosmetic, they expose the flue to extreme heat, which can ignite nearby wood framing. Lakewood’s clay bricks, common in homes built in the 1950s–70s, absorb moisture and freeze, causing the mortar to fail. The fix? Tuckpointing, where a mason replaces damaged mortar with fresh, fire-resistant mix. Costs range from $500 for minor repairs to $3,000+ for full chimney reconstruction. If your bricks are hollow-sounding when tapped or have deep cracks, call a Denver chimney repair specialist before the structure collapses. Ignoring this can void your homeowners insurance, most policies exclude ‘pre-existing’ damage. For Lakewood’s historic homes near the Ridge Road area, historic preservation may also require specific repair methods.

Frequently Asked Questions
My Lakewood home has a wood-burning fireplace. How often should I schedule a chimney sweep Denver crew, and does it change with Denver’s seasons?
Burning wood in Lakewood’s dry climate means you should schedule a chimney sweep every 45 days of use, or at least twice a year if you’re a seasonal burner. The EPA’s Burn Wise program the EPA’s Burn Wise program recommends sweeping after every cord of wood in high-use fireplaces. In Denver, that means sweeps in October (before winter) and March (after spring storms). If you burn softwoods or have a creosote buildup, you may need sweeps every 20–30 days. Never skip a sweep, creosote fires start silently.
I found soot stains on my ceiling near the fireplace. Is this normal, or do I need Lakewood chimney repair?
Soot stains on ceilings or walls are never normal, they mean your chimney isn’t venting properly, and carbon particles are escaping into your home. This is a fire and health hazard. Call a chimney sweep in Lakewood immediately to check for blockages, cracks, or an improperly sized flue. The fix could be as simple as cleaning the flue ($100–$200) or relining it ($1,500–$3,500). Ignoring it risks a chimney fire or CO poisoning. Denver’s high altitude makes symptoms worse, so don’t wait.
My gas fireplace in Lakewood makes a loud ‘whooshing’ noise. Is this a repair issue, or can I fix it myself?
A loud whooshing noise in a gas fireplace usually means the flue is blocked, the draft is weak, or the venting is improper. Never attempt DIY fixes, this can trap carbon monoxide or cause an explosion. Schedule a Lakewood chimney inspection to check for creosote buildup, a collapsed liner, or a blocked chase. The repair might be as simple as cleaning the flue ($150–$300) or adjusting the draft ($200–$500). If your fireplace is over 20 years old, the venting system may need upgrading to meet current Denver codes.
I’m selling my Lakewood home. Does the chimney need a repair or inspection before the sale, and what will buyers check?
Yes, buyers and lenders will demand a Level 2 chimney inspection (where the sweep checks inside the flue) before closing. Denver’s real estate market expects chimneys to be safe and code-compliant, especially in older homes. Fix any cracks, rust, or blockages before listing to avoid last-minute repair costs. A pre-sale inspection costs $150–$250, but catching issues early saves thousands. Ask a Lakewood chimney sweep for a seller’s checklist, they’ll flag problems like missing chase covers or damaged liners that could kill the deal.
