Your chimney is a critical safety feature in your Tewksbury home, but many first-time owners don’t know what they can safely check or when to call a pro. Start with simple visual inspections and basic upkeep, but stop immediately if you see smoke in the room, strong odors, or damage. For anything beyond cleaning creosote buildup or checking for debris, trust a licensed chimney sweep like Eds & Sons Chimney Inc to handle it safely and code-compliant.
Quick checks Tewksbury homeowners can do themselves (and how to do them safely)
Before you call a chimney sweep, there are a few things you can do yourself, safely. Start by inspecting the damper (the metal flap at the base of your chimney) to ensure it opens and closes smoothly. If a part is stuck or corroded, that’s your cue to call a professional instead of trying to fix it. Next, look for debris like leaves, twigs, or animal nests in the fireplace opening or on the roof. Use a flashlight and a long stick (never your hands) to remove loose debris from the fireplace itself. For the chimney cap, check for cracks or missing sections, if it’s damaged, water and critters can enter. Never climb on the roof to inspect the cap; instead, spot-check from the ground or ask a neighbor to help. If your chimney is lined with metal or masonry, also check for visible cracks or mortar deterioration near the base or where the chimney meets the roof. For more details, see our self-inspection tips.
3 red flags in Tewksbury chimneys that mean ‘stop and call a pro immediately’
Some issues are too dangerous to ignore. If you notice smoke spilling into the room when the fireplace is lit, that means your chimney isn’t drawing properly, likely due to a blocked flue or creosote buildup. Strong, lingering odors (like a wet dog or chemical smell) after a fire suggest a leak or animal activity inside the chimney. Finally, rust stains on the fireplace or ceiling mean moisture is entering, which can weaken the structure. Never attempt to fix these yourself. A blocked flue can cause carbon monoxide poisoning, and a leaking chimney can lead to structural damage. If you see any of these, call Eds & Sons Chimney Inc immediately, we serve Tewksbury and nearby towns like Wilmington and Billerica and can diagnose the issue safely.

Preparing your chimney for Tewksbury winters: a step-by-step DIY safety guide
Tewksbury winters mean heavy use of fireplaces, so preparation is key. First, remove any ash from the fireplace using a metal bucket and shovel, never a vacuum. Ash can smolder and cause fires. Next, check the firebox for cracks or loose bricks; if you see gaps larger than a quarter-inch, call a pro. Install or repair a chimney cap if you don’t have one, this keeps out rain, snow, and critters. Test the damper to ensure it seals tightly when closed (use a flashlight to check for light leaks). Finally, schedule a chimney sweep before your first fire of the season. Creosote buildup is a major fire risk, and a professional can remove it safely. For a full checklist, see our fall chimney prep guide. If you’re unsure about any step, don’t guess, call us for a free estimate.
DIY chimney fixes Tewksbury homeowners should avoid, and the dangers they hide
Some chimney tasks are never safe for DIYers. Never attempt to remove creosote yourself, it’s highly flammable and requires specialized tools. Never use chemical cleaners in your chimney; they can damage liners and create toxic fumes. Never ignore a damaged chimney liner, even small cracks can lead to carbon monoxide leaks. Never burn trash, treated wood, or unseasoned firewood, as these create toxic byproducts that corrode chimneys. Never climb onto your roof to inspect or repair the chimney unless you’re trained and equipped, falls are a leading cause of chimney-related injuries. If your chimney has no liner at all, that’s a major safety hazard and requires professional relining. For more on what to avoid, see our common chimney mistakes.

Frequently Asked Questions
I just moved into a Tewksbury home with an old chimney, what’s the first thing I should do before lighting a fire?
The first step is to schedule a Level I chimney inspection with a pro like Eds & Sons Chimney Inc. This checks for structural issues, creosote buildup, and proper draft before you risk using the fireplace. Old chimneys often have hidden damage, and a quick inspection can prevent costly repairs later. If the inspection is clean, we’ll recommend a sweep before your first fire. For more, see our Tewksbury inspection guide.
My Tewksbury chimney has a metal liner, but I’m not sure if it’s still in good shape, how can I tell?
Inspect the chimney liner from the fireplace opening for rust, swelling, or cracks. If light shines through gaps when the damper is closed, damage is likely. Never stick anything into the liner yourself, metal liners can be razor-sharp and unstable. Instead, let us handle a camera inspection, where we examine the entire flue for hidden issues. A damaged liner leaves your home vulnerable to carbon monoxide or chimney fires. For more details, see our relining guide.
I’ve heard Tewksbury’s humidity can damage chimneys, what should I watch for after heavy rain or snow?
After heavy rain, look for water marks on ceilings or walls near the fireplace, this means moisture is seeping in. You might also hear dripping when the fireplace is cold. If you spot mold, mildew, or a damp smell, that’s a sign of water damage. Don’t wait, ongoing moisture weakens brickwork and can lead to expensive fixes. A chimney cap and proper flashing are the best ways to block water entry. For seasonal prep tips, check our fall maintenance guide.
