Creosote is the sticky, tar-like residue that builds up every time you burn wood. In Boulder’s dry climate, this buildup can ignite unexpectedly, putting your home at serious risk. Our certified sweeps use industry-leading brushes and vacuums to clear every flue—from the firebox to the chimney cap—without leaving a speck of soot behind. We don’t just scrape the walls; we inspect for cracks, gaps, or animal nests that could block airflow or let embers escape. Your fireplace will draw better, smell fresher, and stay safer all season long.
Request this service →As a first-time homeowner, you might not know what ‘Level 2’ or ‘Level 3’ even means—but we do. A Level 1 inspection covers the basics: flue, firebox, and accessible chimney. Level 2 adds a video scan to spot cracks in the liner or hidden damage from past fires. Level 3 is reserved for when we find something suspicious—like a collapsed flue or water damage—and need to open walls or floors to assess the full scope. We’ll explain what we see in plain terms and only recommend repairs you truly need.
Request this service →Boulder’s freeze-thaw cycles can turn small cracks in your chimney crown into major problems. We repair spalling bricks, repoint mortar joints, and replace damaged flue liners using materials that last in Colorado’s climate. No temporary patches—just durable fixes that stand up to wind, snow, and sudden temperature swings. We also seal gaps around flashing to keep water out, because a dry chimney is a safe chimney. All repairs come with a 10-year warranty for your confidence.
Request this service →A missing chimney cap is like leaving your front door wide open. Birds, squirrels, and even raccoons love to nest in uncapped flues—blocking airflow and creating fire hazards. Our stainless-steel caps keep critters out, prevent rain from entering, and reduce downdrafts that can fill your home with smoke. We’ll size and install the right cap for your flue, ensuring it stays put through Boulder’s fierce spring winds. Installation takes less than an hour, and we clean up every scrap.
Request this service →Over time, fireplace glass turns cloudy from soot and mineral deposits, making it hard to enjoy the flames. Our gentle, chemical-free cleaning removes stubborn grime without scratching or etching the surface. We also check the gaskets and hinges to ensure your doors seal tightly—preventing smoke leaks and keeping sparks where they belong. Your fireplace will look brand new, and you’ll avoid the frustration of peering through a grimy window.
Request this service →Carbon monoxide is odorless, colorless, and deadly—but it’s also preventable. We use professional-grade detectors to test your chimney and home for CO leaks, especially critical if you’ve recently moved into an older Boulder home. We’ll check your flue’s draft, inspect the firebox for cracks, and test your CO alarms to make sure they’re working. If we find a problem, we’ll explain the risks and fixes in simple terms, so you can act before it’s an emergency.
