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.

AfterChimney Cleaning in Lawrence, MA
Chimney cap and crown work in Lawrence runs $285-$1,850 depending on whether we’re fitting a new cap or rebuilding a spalled crown. Most Lawrence jobs involve the multi-flue brick stacks serving triple-deckers, where one compromised crown lets water into three units at once. Call (351) 444-9705 for a written estimate before any work starts.
Why Lawrence Homes Are Different
The September 2018 Columbia Gas Merrimack Valley disaster pushed thousands of Lawrence residents and landlords to install wood stoves, pellet stoves, and oil burners as replacement heat sources. Those post-disaster conversions created a wave of new or long-dormant chimneys now hitting the 5-7 year mark where professional cleaning and inspection are overdue.
Lawrence’s housing stock is dominated by late-19th- and early-20th-century brick and wood-frame triple-deckers and mill-era tenement row houses, most with multi-flue chimney stacks serving all three units from a single structure. One neglected flue puts multiple tenants at risk and raises landlord liability considerably. The Merrimack Valley’s damp, frigid winters and moisture wicking off the Merrimack River accelerate mortar spalling and brick deterioration, while a six-month heating season builds heavy creosote loads that make annual cleaning a practical necessity.
In densely packed triple-deckers, we routinely find a single brick stack containing three or four unlined or under-maintained flues, sometimes with a furnace flue and fireplace flue sharing the same chase. It’s common to discover that a first-floor landlord’s oil burner flue was never separated from a second-floor tenant’s wood stove insert after a post-2018 conversion.

Before
AfterChimney Cap & Crown in Lawrence
Lawrence’s triple-decker chimneys take a beating from Merrimack Valley freeze-thaw cycles and river moisture, and a failed crown lets water into the flue system of multiple units at once. Chimney Cap & Crown work is where we stop that damage before it reaches the smoke chamber or firebox. Most Lawrence caps and crowns we inspect show spalling, hairline cracks, or missing mortar that would cost far more to ignore than to fix.
Crown Repair
Signs you need it
Look for crumbling mortar at the crown surface, water stains on interior chimney walls, or pieces of concrete in the firebox or cleanout.
What it costs in Lawrence
Crown repair in Lawrence typically runs $450-$850 for partial reconstruction and $850-$1,850 for full crown replacement.
How we do it
We grind out deteriorated material, pour new crown concrete with proper slope and drip edge, and seal with a waterproofing agent rated for freeze-thaw exposure.
Cap Installation
Signs you need it
Your flue has no cap, or the existing cap is rusted through, improperly sized, or missing mesh sides that keep out animals and debris.
What it costs in Lawrence
Single-flue cap installation in Lawrence ranges $285-$495; multi-flue caps for triple-decker stacks run $495-$895 installed.
How we do it
We measure the flue or flue cluster, fabricate or source a stainless steel or copper cap with proper clearance, and secure it with masonry anchors.
What Chimney Cap & Crown Costs in Lawrence
| Item | Typical range in Lawrence |
|---|---|
| Single-flue cap installation | $285 - $495 |
| Multi-flue cap installation | $495 - $895 |
| Crown repair / partial rebuild | $450 - $850 |
| Full crown replacement | $850 - $1,850 |
How long does a crown repair last in Lawrence?
A properly poured and sealed crown lasts 15-25 years in Lawrence’s climate, though freeze-thaw cycles and river moisture will shorten that if the crown was sloped wrong or the concrete mix was weak. We warranty our crown work under the 365-Day Done Right Promise and document the pour with photos under Haven Standard Clause 4.
Can one cap cover multiple flues in a triple-decker?
Yes, and it’s often the right choice for Lawrence’s multi-flue stacks. A single multi-flue cap protects all flues from rain and animals while maintaining proper draft clearance for each unit, and it costs less than individual caps.
Chimney Liner & Rebuild in Lawrence
Lawrence’s post-2018 heating conversions left many chimneys with unlined flues or liners mismatched to new appliance types, and the city’s century-old brick stacks often conceal clay flue tiles cracked by decades of thermal shock. Chimney Liner & Rebuild work in Lawrence focuses on making those flues safe for modern appliances and current NFPA 211 standards.
Stainless Steel Liner
Signs you need it
Your chimney has no liner visible from the top, the clay tile liner is cracked or missing pieces, or a new wood stove or oil burner was installed without a proper liner match.
What it costs in Lawrence
Stainless steel liner installation in Lawrence ranges $1,850-$3,400 for a straight flue and $2,800-$4,500 if offsets or multiple connections are needed.
How we do it
We run a camera to map the flue, drop a correctly sized DuraFlex or Olympia Chimney stainless liner, insulate per manufacturer specs, and connect it to the appliance with a listed adapter.
Partial Rebuild
Signs you need it
The upper courses of brick are spalling or separating, the chimney leans, or mortar joints have eroded to the point that water enters the stack structure.
What it costs in Lawrence
Partial rebuild of the top 3-5 feet in Lawrence runs $1,200-$2,400; mid-stack rebuilds with scaffolding start around $2,800.
How we do it
We dismantle damaged courses to sound brick, rebuild with matching brick and Type N or Type S mortar as appropriate, and install a new crown with proper drainage before capping.
What Chimney Liner & Rebuild Costs in Lawrence
| Item | Typical range in Lawrence |
|---|---|
| Stainless steel liner (straight flue) | $1,850 - $3,400 |
| Stainless steel liner (with offsets) | $2,800 - $4,500 |
| Partial rebuild (top section) | $1,200 - $2,400 |
| Partial rebuild (mid-stack) | $2,800 - $4,200 |
Does my wood stove need its own liner?
Yes, per NFPA 211 and Massachusetts code. A wood stove inserted into a fireplace without a proper liner creates a dangerous clearance gap and can overheat surrounding masonry. We size and install liners specifically for the appliance’s BTU output and venting requirements.
Can a liner be installed without tearing down the chimney?
In most Lawrence cases, yes. We drop flexible or rigid stainless liners down the existing flue from the top, with minimal disruption to interior finishes. Only when the flue is severely offset or the chimney structure is compromised do we need to open walls.
