Denver’s older brick homes hide chimney risks behind their charm. You can spot early problems yourself, like cracks in mortar or soot buildup, but stop immediately if you see rust, water stains, or a damaged liner. Never DIY repairs or deep cleaning; these void warranties and create fire hazards. For a safe inspection, follow these steps and know when to call Maroon Chimney LLC’s licensed team serving Denver and beyond, before small issues become costly disasters.
Step 1: The Exterior Check: Denver’s Brickwork Tells a Story
Start outside near your chimney’s base. Look for cracks wider than 1/8 inch in brick or mortar, common in Denver’s freeze-thaw cycles. Check for rust streaks (a sign of a leaking liner) or water stains on the bricks. If your chimney has a cap, ensure it’s secure and free of debris. Older Denver homes often have terracotta pots, these can crack over time, letting moisture in. Safe DIY tip: Use a flashlight to inspect crevices from ground level; never climb on the roof. If you spot crumbling bricks or missing mortar, that’s a red flag. DIY fixes here can fail fast.
Step 2: The Smoke Chamber Inspection: What’s Visible from the Fireplace?
With the fireplace cold, shine a flashlight up the chimney. Look for glossy black residue (creosote) or white powder (ash). A thin layer of soot is normal, but thick, tar-like buildup means it’s time for a professional chimney sweep. If your chimney has a glass door, check for orange flames (a sign of poor draft) or excessive smoke lingering in the room. Denver’s high altitude can worsen draft issues, if your fire smokes badly, the problem might be blocked flue tiles or a collapsed liner. Never use a vacuum or brush to remove heavy creosote; it’s flammable and toxic. Here’s how to test your draft safely before calling a pro.
Red flags in your Washington Park masonry chimney? Ignore these signs at your peril (and your insurance’s)
If you see any of these, halt your inspection and book a licensed chimney sweep immediately: - Rust on the damper or smoke chamber (sign of a leaking liner, common in older Denver homes with clay liners). - White, sooty smoke or a strong odor when lighting the fire (indicates a cracked liner or blocked flue). - Animals nesting (birds, squirrels) or odd noises (scratching, dropping) from the chimney. - Sagging or separated bricks near the crown (a structural risk after Denver’s winter freeze-thaw cycles). Why? These issues require specialized tools, permits, and repairs, like relining or masonry work. DIY attempts can void warranties, create carbon monoxide risks, or even start fires. Maroon Chimney LLC handles these safely, schedule a visit before winter hits.
Step 3: The Roof Flashing Check: Denver’s Hidden Leak Magnet
From the ground, inspect the metal flashing where the chimney meets the roof. Look for missing caulk, bent seams, or rust. Denver’s hail and snow can loosen flashing over time. If you see water stains on the ceiling near the chimney, moisture is already inside, likely from a failed flashing seal. Safe DIY tip: Use a garden hose to test for leaks (spray near the flashing while someone checks inside for drips). If flashing is damaged, do not replace it yourself, improper installation can create gaps. Older Denver homes often need professional re-sealing to prevent costly water damage.

What You Should NEVER DIY: And Why Denver Homeowners Risk More
Some tasks sound simple but are dangerous, illegal, or warranty-voiding in Denver: - Removing heavy creosote (it’s flammable; improper scraping can cause fires). - Replacing a chimney liner (requires specialized training. DIY liners often fail, leading to carbon monoxide poisoning). - Repairing masonry with duct tape or caulk (this traps moisture, accelerating brick decay). - Ignoring a cracked flue (can release deadly carbon monoxide into your home). Denver’s building codes require licensed inspections for repairs. Common DIY mistakes, like using the wrong mortar, can cost thousands to fix. Let Maroon Chimney LLC handle it right the first time.
