Your Hopkinton chimney works hard year-round, but small issues can become big, costly problems if ignored. Learn the simple, safe checks you can do yourself and the warning signs that mean it’s time to call Andrew & Sons Chimney before trouble starts.
Start with a safe visual check from the ground
Once a month, step back and look up at your chimney from the ground. Use binoculars if needed. Look for leaning bricks, missing mortar, or cracks wider than a credit card. Check the chimney cap—is it still there? A missing cap lets rain, leaves, and animals in, which can clog or damage the flue. Also glance at the flashing (the metal strip where the chimney meets the roof). If it’s bent, rusted, or pulling away, water could be sneaking in. These checks take two minutes and can save you from costly repairs. Never climb onto the roof or use a ladder yourself—leave that to the pros at Andrew & Sons Chimney our full service list.
Check your fireplace’s draft and smell for trouble
When your fireplace is cold, open the damper and hold a lit match or incense stick near the opening. The smoke should rise straight up and out. If it billows back into the room or smells like campfire even when unlit, your chimney may not be drafting properly. A weak draft can mean creosote buildup, a blocked flue, or even a cracked flue liner. Don’t ignore a smoky smell—it’s a sign your chimney isn’t venting safely. If you notice this, stop using the fireplace and call us right away. We’ll inspect and clean it safely request a free estimate.
Look inside the firebox for hidden damage
With the fireplace cold and the damper closed, shine a flashlight inside the firebox. Look for cracked, crumbling, or blackened bricks—these are signs of overheating or moisture damage. Also check for white, chalky stains on the firebox walls; that’s efflorescence, a sign water is seeping in. If you see any of these, don’t light a fire until you’ve had a professional inspection. Small cracks can turn into big problems fast, especially during Hopkinton’s freeze-thaw winters. We can repair fireboxes safely and restore your chimney’s integrity learn more about firebox repair.
Watch for warning signs that mean stop and call a professional
Some problems are beyond DIY. If you see large cracks in the chimney structure, a leaning chimney, or bricks falling inside the flue, call us immediately. Also stop using the fireplace if you notice soot or debris falling into the firebox, or if the damper won’t open or close properly. These signs often point to structural failure or a dangerous blockage. Never attempt to repair masonry or replace a chimney cap yourself—improper repairs can void warranties and create fire hazards. We’re licensed, insured, and trained to handle these risks safely meet our team and credentials.
