Creosote removal in Lakewood chimneys isn’t just about cleaning, it’s about preventing fires and carbon monoxide risks. Johnson Chimney Co. uses specialized tools to break down hardened creosote deposits, ensuring your chimney meets NFPA 211 safety codes and lasts decades longer. Schedule a sweep before winter to avoid costly repairs or dangerous blockages.
What is creosote, and how does it turn chimneys in the Lakewood area into serious fire risks?
Creosote forms as a sticky, flammable residue when wood burns in a fireplace or stove. In Lakewood’s dry climate, where fireplaces see heavy use during winter, creosote builds up faster than in wetter areas. It starts as soot, then hardens into sticky glaze or brick-like crusts, all highly combustible. The Chimney Safety Institute of America (CSIA) warns that creosote is the leading cause of chimney fires, often igniting at temperatures as low as 1,100°F. If your chimney hasn’t been swept since last winter, that buildup could already be a tinderbox waiting for a spark. Johnson Chimney Co. sees cases in Lakewood where homeowners ignore creosote until it’s too late, forcing costly relining or even chimney replacement. /services/ More on this in what we do page.
How Johnson Chimney Co. removes creosote safely in Lakewood homes, step by step
Our process starts with a Level 2 inspection (inside the chimney) to assess creosote stage and structural risks. For Stage 1 (soot), we use rotary brushes and vacuum systems to remove it cleanly. For Stage 2 (glaze), we apply a specialized creosote solvent that softens the deposit before brushing it out. Stage 3 (hard creosote) requires chemical breakdown or even mechanical scraping, tasks we handle with professional-grade tools to avoid damaging your chimney liner. After removal, we inspect for cracks, rust, or blockages that could trap future creosote. Unlike DIY methods or fly-by-night sweeps, our crew follows NFPA 211 standards and leaves your chimney safer than when we arrived. /areas/lakewood-co/ Read up on contact the office.
Carbon monoxide risks in Lakewood chimneys: Why creosote isn’t the only danger
Creosote buildup isn’t just a fire risk, it can also block proper airflow, causing carbon monoxide (CO) to back up into your home. Lakewood’s older homes, especially those near I-70 or in the foothills, often have chimneys with poor draft due to age or obstructions. The U.S. Environmental Protection Agency (EPA) reports that improper chimney maintenance is a top cause of CO poisoning. Johnson Chimney Co. tests for CO leaks during every sweep and recommends installing a CO detector near your fireplace if your chimney shows signs of poor ventilation. We’ve seen cases in Lakewood where homeowners assumed their chimney was fine until a CO detector saved their family. /tips/chimney-safety-lakewood-homeowners-guide/ More on this in our crew and certifications.
Lakewood chimney sweep codes: What you’re legally required to know (and how we help)
Colorado requires chimneys to be inspected annually if they’re used (NFPA 211). Lakewood’s building codes align with this, meaning if you burn wood, you’re legally obligated to have a certified sweep like Johnson Chimney Co. check for creosote, cracks, and blockages. Many homeowners skip this because they don’t realize the fines for non-compliance can exceed $500, or worse, the risk of a chimney fire. Our crew carries full liability insurance and CSIA certification, so you’re protected. We also provide written reports detailing any hazards found, which you can use for home insurance or future repairs. /blog/chimney-inspection-code-compliance-lakewood-homes/ Full details in the full service area.
How often should you schedule a Lakewood chimney sweep? A local expert’s timeline
The CSIA recommends sweeping at least once a year for homes that burn wood, but Lakewood’s high-elevation climate and frequent fireplace use often mean more frequent cleanings are needed. If you burn cord wood, we suggest sweeping every 45–60 days. For pellet stoves, every 2–3 months suffices. After a chimney fire or if you notice excessive smoke, schedule an emergency sweep immediately. Our crews in Lakewood often see homeowners wait until they smell gas or see soot in their living room, by then, creosote has already hardened into a dangerous layer. /tips/how-often-service-chimney-lakewood-homeowners-schedule/ You can also review Chimney Sweep in Wheat Ridge, CO page.
What happens during a chimney sweep visit in the Lakewood area, and how can you get your home ready?
Our process takes 60–90 minutes for most Lakewood homes, depending on creosote buildup. We arrive with a truck-mounted vacuum, brushes, and inspection tools, then work from the roof down. To prepare, clear furniture from the fireplace area and ensure pets are secured, our crew moves quickly but safely. We’ll test for CO leaks, check your damper, and leave your chimney spotless. Pricing starts at $120 for basic sweeps but rises with creosote removal or repairs. Many Lakewood homeowners bundle their annual sweep with a fireplace tune-up for added safety. /pricing/
Signs your Lakewood chimney needs creosote removal right now (don’t ignore these)
If you notice any of these, call Johnson Chimney Co. immediately: - A strong, sweet-smelling odor when the fireplace is lit (glaze-stage creosote). - Excessive smoke or soot in your home (blocked chimney). - A yellow or flickering flame instead of blue (poor combustion). - Cracks in the chimney crown or masonry (water entry worsens creosote). We’ve responded to Lakewood emergencies where homeowners delayed too long, leading to chimney fires that damaged roofs and required $10,000+ repairs. /blog/7-signs-your-lakewood-chimney-needs-repair-or-masonry-restoration/

Frequently Asked Questions
My chimney smells like gas after lighting the fireplace, could it be creosote-related?
Yes. Creosote buildup or a blocked chimney can trap gases, causing that smell. It’s also a sign of poor draft or a cracked liner. Never ignore this, schedule a Lakewood chimney sweep immediately to avoid carbon monoxide poisoning. Our crew tests for CO leaks during every inspection.
Why does my Lakewood chimney need sweeping if it’s only used occasionally?
Even light use leaves behind creosote. Lakewood’s dry climate speeds up buildup, and the substance hardens over time. The Chimney Safety Institute of America advises yearly sweeps to prevent hidden dangers, no matter how often you use your fireplace. Skipping it could mean overlooking risks until a fire or carbon monoxide leak forces action.
Is it safe to use my fireplace immediately after a sweep in the Lakewood area?
You can, but only after we verify the chimney is free of debris and creosote. We’ll give you a written clearance if everything checks out. Never relight until you’ve received our approval, some creosote buildup needs extra drying time before it’s safe.
How do I know if my Lakewood chimney has hard creosote that needs professional removal?
Hard creosote looks like black, crusty deposits or shiny glaze inside the chimney. If you see this, DIY methods won’t work, it requires chemical breakdown or mechanical scraping. Johnson Chimney Co. uses specialized tools to remove it safely without damaging your chimney.
