A safe chimney keeps your Durham home warm and your family safe. This guide shows you exactly what to check from the ground up—and when to stop DIY and call Mateos Chimney LLC for expert help.
Step 1: Check the Chimney Exterior from the Ground
Stand back 10–15 feet and look up at your Durham chimney. Use binoculars if needed. Look for leaning bricks, missing mortar, or cracks wider than a credit card. Check the chimney cap—it should be intact and free of debris. If you see leaning, gaps, or a missing cap, stop DIY and call a pro. A stable chimney is your first line of defense against Durham’s summer storms and winter drafts.
Step 2: Inspect the Flashing and Roof Penetration
From the ground, look where the chimney meets the roof. Flashing should be tight and sealed—no rust, gaps, or peeling sealant. If you see daylight through the flashing or water stains on the ceiling below, stop DIY and call Mateos Chimney LLC. Durham’s humid summers and freeze-thaw winters make roof leaks a fast track to chimney damage and mold.
Step 3: Open the Damper and Look Inside the Firebox
With the damper fully open, use a flashlight to inspect the firebox walls and floor. Look for heavy creosote buildup (black, tarry, or shiny), white staining (efflorescence), or cracks wider than 1/8 inch. If you see more than 1/8 inch of buildup or any cracks, stop DIY and call a pro. A cracked firebox can leak deadly carbon monoxide into your Durham home.
Step 4: Check the Smoke Chamber and Flue from the Attic (If Safe)
If your Durham home has an attic access, carefully shine a light up the flue. Look for obstructions like bird nests, leaves, or debris. Also check for smooth, unbroken flue tiles—no cracks or missing sections. If you see blockages or damaged tiles, stop DIY and call Mateos Chimney LLC. A blocked or cracked flue is a silent killer—carbon monoxide can seep into living spaces.
Step 5: Watch for Warning Signs During Use
When you burn a fire in your Durham fireplace, watch the smoke. If it curls back into the room or smells strongly of smoke, your chimney may not be drafting properly. Also listen for loud popping or rumbling—this can signal a blockage or excessive creosote. If you notice either, stop using the fireplace and call a pro immediately. These signs mean your chimney is failing to do its job—and putting your family at risk.
What You Should NEVER DIY — and Why
Never climb onto your roof to inspect the chimney cap or flashing—Durham’s steep roofs and summer storms make this a fall risk. Never use chemicals or brushes you bought online to clean creosote—improper tools can damage the flue liner or push debris into the home. Never ignore a cracked flue tile or missing chimney cap—these are code violations and fire hazards. These jobs require a licensed pro with liability insurance and Durham-specific training.

Frequently Asked Questions
How much does a Durham chimney inspection cost compared to a full cleaning?
A basic Durham chimney inspection starts around $120 and takes 30–45 minutes. A full cleaning averages $180–$250 and takes 60–90 minutes. If your chimney hasn’t been serviced in over a year, schedule both—it’s the safest and most cost-effective way to protect your home.
Can I burn a small fire in Durham after a DIY inspection if I didn’t clean it?
No. If you saw more than a thin layer of creosote or any cracks during your inspection, burning can ignite a chimney fire. Durham’s wood is often wet or resinous, increasing creosote buildup. Call Mateos Chimney LLC before lighting another fire—your safety isn’t worth the risk.
How often should I schedule a chimney sweep in Durham before winter hits?
Durham homeowners should schedule a chimney sweep every 1–2 years, depending on use. If you burn more than 3 cords of wood annually, or use unseasoned wood, schedule annually. Mateos Chimney LLC can help you plan the best timing for your home.
