Rosemount’s first cold snaps mean fireplaces are about to get heavy use. If your home has a brick chimney or clay liner, now’s the time to check for hidden damage before creosote hardens or winter storms test your masonry. Gonzalez and Brian Chimney Co. specializes in older homes, here’s what to look for and why it’s critical this month.
Why Rosemount’s older brick chimneys need a fall sweep, and what to check before winter
Rosemount’s historic neighborhoods have homes with brick chimneys built decades ago, and those masonry joints don’t last forever. Before you light your first fire, check for: - Cracks in the brickwork (especially near the roofline or where the chimney meets the house). These let moisture seep in, weakening mortar over time. - Loose or missing bricks, common after last winter’s freeze-thaw cycles. A single shifted brick can let sparks escape or let rain erode the flue. - Clay liner gaps or collapse, older homes often have clay flue liners that crack under heat stress. If your chimney hasn’t been inspected in over a year, assume the liner needs checking. Learn how to spot clay liner damage in our Rosemount guide. Skip this step, and creosote buildup (that sticky black gunk) will harden into a flammable crust by December.

Should I Sweep My Chimney Myself? Rosemount’s Humid Fall Means DIY Risks
If you’ve never swept a chimney, don’t. Rosemount’s fall humidity turns creosote into a stubborn, flammable tar, especially in older brick chimneys where drafts are weaker. A DIY brush might miss creosote in crevices or damage your clay liner. Instead: - Book a certified sweep before your first fire. Our team uses motorized tools to remove buildup safely, even in tight flues. - Ask about a Level 2 inspection if your chimney shows signs of wear. This checks the liner, smoke chamber, and masonry for hidden issues. See what’s included in a full inspection. - Check your damper, a stuck or missing one lets cold air rush in, wasting fuel and risking carbon monoxide buildup. We’ve seen Rosemount homes with dampers that haven’t worked since the 1980s. Pricing varies by chimney height and condition, but we offer free estimates. Get started here, and if you’re unsure whether your chimney’s safe, ask us. We’ve restored brick chimneys in Rosemount for years, including this recent project on 12th Street.
