Creosote is a tar-like byproduct of wood burning that coats your chimney’s walls and ignites at just 451°F—hot enough to start a chimney fire in minutes. Our Boulder-area sweeps use rotary brushes and HEPA vacuums to strip away layers of creosote, soot, and debris down to bare masonry. We don’t just scrape the surface; we clear the entire flue, smoke chamber, and damper to restore proper draft and reduce smoke spillback. Expect zero dust in your living room, no mess on your floors, and a chimney that draws cleaner from day one. Pricing is fixed by flue type, so you’ll know the cost upfront—no hourly bait-and-switch.
Request this service →A proper inspection isn’t a quick peek—it’s a full diagnostic of your chimney’s health. We start with a Level 1 visual sweep of accessible areas, then move to Level 2 with a camera to inspect the flue liner, joints, and crown. If we spot cracks, gaps, or deterioration, we’ll flag them with photos and a repair recommendation. No vague ‘possible issues’—just clear evidence and a straight answer on what needs fixing. Boulder’s freeze-thaw cycles can crack masonry in as little as two years, so catching damage early saves thousands in rebuilds. Inspections start at $129 and include a written report.
Request this service →From cracked flue liners to crumbling mortar joints, we repair what others ignore. Our team uses high-temperature mortar and stainless-steel chimney liners to seal leaks and reinforce weak spots. We don’t slap on temporary fixes—we rebuild to code, so your chimney passes any Boulder County inspection. Common repairs include crown sealing, tuckpointing, and liner replacements, all backed by a 5-year warranty. We source materials locally to avoid delays, and most jobs wrap in under a day.

Request this service →A missing chimney cap is like leaving your front door wide open—water, birds, and leaves will find their way in. We install copper, stainless-steel, and mesh caps tailored to your flue’s dimensions, with a 20-year lifespan. Caps block up to 90% of water intrusion, which is critical in Boulder’s snowy winters and sudden downpours. Installation takes 30 minutes, and we include a free sweep afterward to clear any debris dislodged during the process. No cap? No problem—we’ll source one the same day.
Request this service →Your wood stove or fireplace works harder in Boulder’s high-altitude air, burning hotter and faster than at sea level. We clean ash from fireboxes, lubricate moving parts, and adjust gaskets to prevent heat loss. We also check for creosote buildup in stovepipes and recommend fuel adjustments to reduce emissions. Maintenance visits cost $99 and include a draft test to ensure your appliance vents properly. Skip this step and you risk inefficient burns, smoke spillback, and even carbon monoxide leaks—all preventable with a 60-minute tune-up.
Request this service →Boulder’s 300+ sunny days a year mean intense UV exposure, while sudden storms can soak unprotected chimneys in minutes. Our siloxane-based waterproofing penetrates brick and mortar to create a breathable barrier that repels water but lets vapor escape. Applied in under an hour, it prevents spalling, efflorescence, and liner corrosion for up to 10 years. We pair it with a free inspection to identify any existing damage. Waterproofing costs $249 and is the cheapest insurance policy for your chimney’s longevity.
