Denver pre-fire checklist: what to check before lighting your first fire this season
Denver’s elevation and dry air turn creosote into a sticky hazard by October. Start with a quick visual: Is your chimney cap loose? Are there cracks in the masonry near the roofline? (A cracked crown lets rain seep in, freezing and expanding, common in older homes near Speer Boulevard.) For gas fireplaces, check the vent for rust or soot buildup; wood-burning chimneys need a full sweep if you’ve used them even once this season. /services/ crews spot these issues before they become emergencies. Pro tip: If your damper sticks or smells like gas, don’t light it, call us first. /areas/aurora-co/ and /areas/lakewood-co/ homeowners report these problems most in October. Full details in what we do page.
Sweep before or after your first fire this year? Here’s the right order.
This is the #1 question we hear in Denver. The answer depends on your chimney’s age and how often you burn. If it’s been more than 6 months since your last sweep or you’ve burned through a full cord of wood, sweep before lighting up. Why? Creosote hardens when cold, scraping it after a fire is harder and messier. Gas fireplaces need annual inspections too; our /compare/wood-vs-gas-fireplace/ guide explains why. For homes in /areas/westminster-co/ or /areas/arvada-co/, where older brick chimneys are common, we recommend a Level 2 inspection if you notice white powder (efflorescence) on the fireplace hearth. /news/fall-chimney-sweep-update-denver-homeowners/ covers what to watch for.
