With July thunderstorms rolling through Longmont, now’s the time to inspect your chimney for summer safety. Creosote buildup and cracked flues can turn a summer grill session into a fire hazard. Schedule your Chimney Sweep in Longmont before the next storm hits.
Why July chimney checks matter for Longmont homes
Longmont’s summer storms can push debris into uncapped chimneys, while high humidity after rain increases creosote buildup. A July inspection catches cracks in the flue tile or missing mortar joints before they let water seep into your masonry—especially critical for older homes near the St. Vrain Greenway or in the historic district. Even gas fireplaces need a Level 1 inspection to ensure vents aren’t blocked by summer pollen or critters nesting in the cap. Schedule your free estimate to confirm your chimney meets Longmont’s 2024 fire code standards.
What to look for on your Longmont chimney this month
Start with the crown: if it’s cracked or missing chunks, water will pool and erode the masonry near 3rd Avenue homes. Check the cap for rust or gaps—Longmont’s summer hail can dent thin metal. Inside, use a flashlight to spot creosote glaze thicker than a credit card; that’s a Level 2 inspection trigger. For Niwot or Erie neighbors, inspect the chimney’s exterior for leaning—common after spring soil shifts near the Boulder County line.

Should you DIY or call a pro for your Longmont chimney this July?
If you’re comfortable on a ladder, clear debris from the cap and check for obvious cracks—but don’t probe flue tiles; they’re fragile. For anything beyond a visual sweep, hire a CSIA-certified pro. Longmont’s altitude and humidity mean creosote hardens faster than in Denver, so a professional brush can remove layers a homeowner misses. Is it worth the cost? Compare DIY risks (carbon monoxide leaks) to a pro’s $129 Level 1 inspection—especially if your home’s near the Lefthand Creek floodplain where moisture lingers.
