Older Arlington homes built before 1980 often hide hidden chimney damage: cracked liners, creosote buildup, or failing masonry. A professional chimney sweep can spot these issues before they spark a fire or flood your living room. Don’t wait until the first cold snap—schedule a sweep now to protect your family and your historic home.
1. Creosote layers thicker than a credit card: a silent fire hazard
A chimney inspection is a visual and instrumental check of your flue, liner, smoke chamber, and exterior masonry to spot damage, blockages, or hazardous deposits like creosote. In older Arlington homes—especially those with original brickwork on Arlington Street or Main Street—creosote can build up in layers thicker than a credit card in just one heating season. The Chimney Safety Institute of America recommends cleaning when deposits exceed 1/8 inch, but in Arlington’s older homes, we often find 1/4 inch or more. That’s enough to fuel a chimney fire that can spread to your roof in minutes. If you burn more than two cords of wood per year or notice a strong campfire smell even when the fireplace is cold, call a sweep immediately. Ed Chimney Company provides certified sweeps who use rotary brushes and HEPA vacuums to remove every gram of creosote without tracking soot through your home.
2. White, chalky stains on bricks: efflorescence and moisture damage
White, fuzzy stains on your chimney’s exterior—especially on the Arlington-side facades of homes near the Minuteman Bikeway—are efflorescence, a sign your bricks are absorbing water. In Arlington’s damp springs and snowy winters, water seeps into porous masonry, freezes, and cracks mortar joints. Left unchecked, this leads to spalling bricks and a chimney that leans like the Leaning Tower of Pisa. A professional chimney waterproofing service seals the bricks with a vapor-permeable siloxane treatment that lets moisture escape but blocks water entry. We also repoint cracked joints with Type N mortar matched to your brick’s age and color—critical for historic homes on Arlington’s tree-lined streets.
3. Rust on the damper or flue cap: liner failure in older systems
If you see orange rust on your damper, flue cap, or even inside the firebox, your chimney liner is likely failing. Many Arlington homes built before 1970 have clay tile liners that crack under freeze-thaw cycles or single-wall metal liners that corrode. A cracked liner exposes combustible wood framing to heat and embers, creating a hidden fire risk. The National Fire Protection Association’s NFPA 211 code requires a liner in good condition for safe operation. Our team inspects liners with a chimney camera and recommends stainless steel liners for durability or cast-in-place liners for a custom fit in tight spaces—both backed by a 5-year workmanship warranty.

4. Smoke pouring into the room instead of up the flue
When your fireplace smokes into the living room—especially in Arlington’s older Victorians on Pleasant Street or colonials on Massachusetts Avenue—it’s usually a blocked flue, a cracked liner, or negative indoor pressure from exhaust fans. Older homes often lack modern air-sealing, so a running kitchen or bathroom fan can pull smoke back down the chimney. Before you light another fire, schedule a Level 2 inspection with a sweep who checks for obstructions, a proper smoke shelf, and a functioning damper. Ed Chimney Company includes a free pressure test with every full chimney inspection to diagnose drafting issues before they ruin your evening.
5. Crumbling mortar joints and leaning chimney top
If your chimney leans more than an inch or you see missing mortar between bricks on the Arlington-side rooftops, it’s time for masonry repairs. Older chimneys weren’t built to modern seismic standards, and Arlington’s clay soil expands when wet, pushing foundations and chimneys out of plumb. We repoint joints with a mortar mix that matches your brick’s age and color, then install stainless steel ties to anchor the chimney to the roofline. For severely leaning stacks, we may recommend a full rebuild of the top 3–4 feet to restore structural integrity. All work is done with scaffolding for safety and includes a 10-year warranty on repointing.
6. Animal nests or debris blocking the flue: a seasonal risk
Squirrels, raccoons, and even bees love to nest in unused chimneys—especially in Arlington’s wooded neighborhoods like West Arlington. A blocked flue can trap deadly carbon monoxide in your home or cause a chimney fire when you light the first fire of the season. The U.S. Environmental Protection Agency’s Burn Wise program warns that even small nests can restrict draft and force smoke back into your living room. Before you close the flue for summer, install a chimney cap with a 3/4-inch mesh screen to keep animals out while allowing proper airflow. We also recommend a Level 1 inspection each spring to clear any springtime debris.
7. Age of the chimney: Arlington homes built before 1980 need proactive care
If your Arlington home was built before 1980—common in neighborhoods like East Arlington or near the Arlington Center Historic District—your chimney is likely original brick with no liner or a deteriorated clay liner. These systems weren’t designed for modern heating loads or EPA-certified wood stoves. The Chimney Safety Institute of America recommends a Level 2 inspection every five years for pre-1980 homes, even if you haven’t noticed issues. At Ed Chimney Company, we combine a visual sweep with a chimney camera to document liner condition, mortar integrity, and flue dimensions. We’ll provide a free estimate for repairs or upgrades, including liner installation, waterproofing, or cap replacement—all tailored to your home’s age and style.

Frequently Asked Questions
My Arlington home has original brickwork from the 1920s. How often should I schedule a chimney sweep?
For pre-1980 Arlington homes like those on Appleton Street or Pleasant Street, schedule a Level 2 inspection every three to five years and a sweep annually if you burn more than two cords of wood per year. Older masonry absorbs moisture and cracks faster in Arlington’s freeze-thaw climate.
Why does my Arlington chimney smell like a campfire even when it’s not in use?
A persistent campfire odor usually means creosote deposits inside the flue are absorbing moisture and releasing odors into your home. In older Arlington homes, creosote can hide in cracks in the liner or behind loose bricks. A professional sweep with rotary brushes and HEPA vacuuming removes the source and restores fresh air.
Can I waterproof my Arlington chimney myself with a DIY sealer from the hardware store?
DIY waterproofing sealers often trap moisture behind the bricks, accelerating spalling and cracking. Ed Chimney Company uses vapor-permeable siloxane treatments that allow bricks to breathe while blocking water. Our crews also repoint cracked joints with Type N mortar matched to your brick’s age for lasting protection.
How much does a chimney sweep cost for an older Arlington home?
For older Arlington homes, expect $220–$350 for a Level 1 sweep and inspection, $350–$550 for a Level 2 camera inspection, and $1,200–$2,500 for liner installation or repointing. Costs vary by flue size, liner type, and access. Ed Chimney Company offers free estimates and financing options for Arlington homeowners.
