Upgrading your Mt. Juliet chimney can improve safety and efficiency, but not all tasks are DIY-friendly. Learn what you can safely handle yourself and when to call a licensed pro to avoid costly repairs or dangerous mistakes.
Safe DIY checks before you upgrade
Start with a visual inspection from the ground using binoculars to spot obvious damage like missing bricks or leaning sections. Check your chimney cap for rust or gaps—replace it if it’s damaged to keep out debris and critters. Clean the firebox and flue of ash and soot using a shop vacuum and a chimney brush sized for your flue. Seal any small cracks in the firebox with high-temperature mortar, but only if they’re under 1/4 inch wide. Avoid climbing on the roof or using ladders unless you’re experienced and have a spotter. For more detailed guidance, see our Mt. Juliet Chimney Self-Inspection Guide.
What to inspect inside your Mt. Juliet fireplace and flue
Shine a flashlight up the flue from the firebox to check for creosote buildup, which looks like black, tarry, or shiny deposits. Heavy creosote (more than 1/8 inch) must be removed by a pro to prevent chimney fires. Look for white, chalky stains on the flue walls—this is efflorescence, a sign of water damage that can weaken masonry. Check the damper for rust or warping; it should open and close smoothly. If you see any of these issues, pause your DIY plans and call a pro. Learn more about common problems in our Common Chimney Mistakes Mt. Juliet Homeowners Make.
Warning signs that mean stop and call a pro now
If your chimney leans more than a few degrees, has large cracks wider than a credit card, or shows signs of water pooling at its base, these are red flags for structural failure. A strong, musty odor coming from your fireplace in warm weather often signals a hidden water leak or mold. If you hear loud popping or see smoke backing up into the room when the fireplace is lit, your flue may be blocked or improperly sized. Never attempt to fix these issues yourself—call a licensed chimney sweep immediately. For emergency service, visit our Mt. Juliet Emergency Chimney Service.
Upgrades you should never DIY in Mt. Juliet
Replacing or relining a flue, installing a new chimney cap or crown, or repairing masonry with structural cracks are jobs that require specialized tools, permits, and expertise. DIY relining can void your homeowner’s insurance if done incorrectly, and improper crown repairs can lead to water damage that ruins your chimney in just one winter. Upgrading to a stainless steel liner or installing a new chimney chase also falls under professional work. For a full list of what we handle, check our services.

Local climate tips for Mt. Juliet chimney care
Mt. Juliet’s humid summers and cold winters accelerate wear on chimneys. After heavy rain, check for water stains on your ceiling near the fireplace—this could mean your chimney crown is cracked. In fall, clear leaves and pine needles from the chimney cap to prevent blockages. Before winter, test your damper’s seal by holding a lit match near the closed damper—if smoke is drawn into the room, you need a tighter seal.

Frequently Asked Questions
My Mt. Juliet chimney has white stains on the bricks—is this a DIY fix or should I call a pro?
Those white stains are likely efflorescence, a sign of water seeping through your chimney. While you can scrub the surface with a stiff brush and water, the real issue is waterproofing the masonry from the inside out. Call a pro to apply a breathable sealant and check for cracks in the crown or flashing that are letting water in.
Why does my Mt. Juliet fireplace smell like mildew even when it’s not in use?
A musty odor usually means moisture is trapped inside your chimney, often from a cracked crown or missing cap. This creates the perfect environment for mold and mildew. A professional chimney sweep can clean the flue and apply a deodorizing treatment, but the root cause must be fixed to prevent it from returning.
Can I just add a chimney cap myself to keep out squirrels and rain in Mt. Juliet?
A chimney cap is a great DIY project if you’re comfortable on a ladder and have the right tools. Measure your flue first—caps must fit snugly to block pests and water. If your chimney is tall or has a steep pitch, hire a pro to ensure it’s installed safely and securely. A poorly fitted cap can do more harm than good.
