Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We’re Level Two Chimney Co., and we’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented record when it was done. In Waltham, our crews spend as much time documenting liner condition as they do removing creosote, because the city’s 1880s-1920s triple-decker stock often hides deteriorated clay tile or missing liners beneath what looks like a routine cleaning job. Our Chimney Cap & Crown and Chimney Liner & Rebuild work accounts for a significant share of what we find after the camera goes down the flue.
Why Waltham Homes Are Different
Waltham’s “Watch City” building boom left the Charles River flatlands dense with triple-deckers and worker rowhouses whose original masonry chimneys were sized for coal furnaces. Decades of conversions to oil and gas, often without proper liner installations, mean deteriorated or absent clay tile liners are common. This failure pattern concentrates in Waltham’s worker-housing core in a way wealthier neighbors like Weston simply don’t share.
The valley location brings hard New England winters with freeze-thaw cycles that spall brick and erode mortar into March. River moisture accelerates efflorescence and interior liner cracking, so pre-season inspections in Waltham routinely uncover structural damage layered on top of creosote buildup. In the dense triple-decker blocks around Moody Street and the South Side, a single chimney stack often serves all three units, meaning one tenant’s uncleaned wood insert can degrade the flue serving the gas appliance two floors above, creating carbon monoxide risk across the entire building.
Our Main Waltham Services
Most Waltham homeowners who call us need one of these three services:
Chimney Cleaning & Sweep in Waltham
We remove creosote buildup and obstructions from flues serving wood, gas, and oil appliances in Waltham’s triple-deckers, Capes, and ranches. Every sweep includes an NFPA 211 Level 2 camera inspection, because Waltham’s conversion history means we often find damaged or missing liners that a brush-only visit would miss.

Before
AfterChimney Cap & Crown in Waltham

Waltham’s century-old masonry chimneys were built without the protective overhangs modern codes require, and the Charles River valley’s wet winters accelerate crown deterioration that starts as hairline cracks and ends with water pouring into the flue. A properly fitted cap and intact crown are the only barriers between Waltham’s freeze-thaw cycles and the interior liner system. Our Chimney Cap & Crown work follows NFPA 211 standards with materials from Gelco and Olympia Chimney, sourced through our Haven buying network.
Cap Installation
Signs you need it
Your flue has no cap, or the existing cap is rusted through, improperly sized, or allowing rain and animal entry.
What it costs in Waltham
Standard single-flue cap installation runs $180-$340; multi-flue caps for Waltham’s shared triple-decker chimneys range $340-$580.
How we do it
We measure the flue opening, select a stainless steel or copper cap with proper mesh clearance, and secure it with masonry screws or a collar mount that won’t damage the flue tile.
Crown Repair
Signs you need it
The concrete crown has visible cracks, pooling water, or missing chunks that expose the brick courses below to saturation.
What it costs in Waltham
Crown repair with poured concrete or pre-formed slab ranges $450-$850; extensive rebuilds with overhang correction run $850-$1,400.
How we do it
We grind out cracks, apply bonding agent, pour new crown mix with proper slope and drip edge, and seal with breathable masonry sealer after cure.
What Chimney Cap & Crown Costs in Waltham
| Item | Typical range in Waltham |
|---|---|
| Single-flue cap installation | $180 - $340 |
| Multi-flue cap installation | $340 - $580 |
| Crown repair | $450 - $850 |
| Crown rebuild with overhang | $850 - $1,400 |
How long does a crown repair last in Waltham?
A properly poured crown with correct slope and overhang lasts 15-25 years even in Waltham’s wet freeze-thaw climate; we warranty our crown work for 5 years under the 365-Day Done Right Promise extended to full term. Call (978) 861-1012 for an exact quote - estimates are free.
Can a cap stop all water in a Waltham triple-decker chimney?
A cap blocks rain and snow entry at the flue top but won’t fix crown cracks or porous brick below; we inspect the full stack before recommending caps alone. Call (978) 861-1012 for an exact quote - estimates are free.
Chimney Liner & Rebuild in Waltham

Waltham’s coal-era chimneys were never meant to vent modern gas appliances, and the conversions done in the 1960s-1980s often left clay tile liners cracked, unconnected, or entirely absent. In the triple-decker core around Moody Street, we regularly find flues where multiple units share a single unlined passage, a condition that violates current NFPA 211 and creates carbon monoxide exposure risk. Our Chimney Liner & Rebuild work installs listed stainless steel or flexible liners with proper sizing for each appliance.
Stainless Steel Liner
Signs you need it
Clay tile chunks appear in the firebox, the flue fails a Level 2 camera scan, or a gas appliance vents into an unlined masonry passage.
What it costs in Waltham
Stainless steel liner installation for a single appliance runs $1,800-$3,200; multi-appliance or multi-flue systems in Waltham’s triple-deckers range $2,800-$4,500.
How we do it
We drop a video camera to assess the full flue, measure for proper appliance sizing, install an insulated stainless liner with top plate and bottom connector, and pressure-test gas connections where applicable.
Partial Rebuild
Signs you need it
The top courses of brick are spalled or loose, the crown has collapsed into the flue, or the chimney leans above the roofline.
What it costs in Waltham
Partial rebuild from the roof up typically runs $2,200-$4,000 depending on access and scaffold requirements in Waltham’s dense neighborhoods.
How we do it
We dismantle to sound masonry, install a new concrete crown with proper overhang, and rebuild with matching brick and type-N mortar rated for freeze-thaw exposure.
What Chimney Liner & Rebuild Costs in Waltham
| Item | Typical range in Waltham |
|---|---|
| Stainless steel liner, single appliance | $1,800 - $3,200 |
| Stainless steel liner, multi-appliance | $2,800 - $4,500 |
| Partial rebuild (roof up) | $2,200 - $4,000 |
| Full chimney rebuild | $6,500 - $12,000 |
Do all Waltham chimneys need a new liner?
No - intact clay tile that passes a Level 2 camera scan and is properly sized for the appliance can remain; we only recommend replacement when the scan shows damage or code violation. Call (978) 861-1012 for an exact quote - estimates are free.
How long does liner installation take in Waltham?
Most single-appliance liners are installed in one day; triple-decker multi-flue systems may require two days to properly isolate and connect each unit’s appliance. Call (978) 861-1012 for an exact quote - estimates are free.
