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.

Chimney cap and crown work in Cambridge typically runs $650-$2,400 depending on whether we’re sealing a cracked crown or installing a multi-flue cap on a triple-decker stack. Most Cambridge jobs need more than a sweep because the city’s pre-WWI clay tile chimneys weren’t built for today’s heating loads and freeze-thaw cycles. Call (508) 850-0489 for a written quote before any work starts.
We dispatch crews from our Boston office and serve Cambridge properties with background-checked, uniformed technicians who carry license numbers on every page of documentation. Every visit includes an NFPA 211 Level 2 camera inspection down the flue and a stamped photo record under Haven Standard Clause 4.
Why Cambridge Homes Are Different
Cambridge’s housing stock is overwhelmingly pre-WWII wood-frame triple-deckers and brick row multifamily buildings from 1880-1925, nearly all with original clay tile-lined masonry chimneys that have never been relined. A single stack often serves two or three separate apartments simultaneously, which makes chimney maintenance a landlord-compliance issue under city fire code.
Our freeze-thaw cycles hit harder here than in inland suburbs. Temperatures cross 32°F dozens of times each winter, aggressively deteriorating lime mortar joints and clay tile liner sections. In Cambridgeport and East Cambridge, we regularly find tenants have installed wood-burning inserts into flues that were bricked up during mid-century fuel conversions and haven’t been swept in 40-plus years.

AfterChimney Cap & Crown in Cambridge
Cambridge’s triple-decker and multifamily brick buildings put extraordinary demand on chimney caps and crowns. A single stack serving three units generates three times the exhaust volume, yet the crown was sized for one coal furnace in 1910. Freeze-thaw cycles open hairline cracks in the crown within a season, and missing or rusted caps let water pour onto already-saturated masonry. We install Chimney Cap & Crown systems sized for the actual load, with materials from Copperfield and Famco sourced through Haven’s buying network.
Crown Repair
Signs you need it
Visible cracks in the crown surface, water staining on interior flue walls, or pieces of concrete found in the firebox after heavy rain.
What it costs in Cambridge
Crown repair in Cambridge typically runs $650-$1,200 for crack sealing and resurfacing, or $1,800-$2,400 for full crown rebuild on multi-flue stacks.
How we do it
We grind out cracked material, apply a bonding layer, and pour new crown mix sloped to shed water, with a documented photo record of each stage.
Cap Installation
Signs you need it
Rust streaks down the chimney face, water in the firebox, bird nests or debris visible at the flue top, or no cap present at all.
What it costs in Cambridge
Single-flue cap installation in Cambridge ranges $280-$550; multi-flue caps for triple-decker stacks run $650-$1,100 installed.
How we do it
We measure each flue precisely, select a stainless or copper cap with proper mesh screening, and secure it with masonry anchors rated for wind loads.
What Chimney Cap & Crown Costs in Cambridge
| Item | Typical range in Cambridge |
|---|---|
| Single-flue cap installation | $280-$550 |
| Multi-flue cap installation | $650-$1,100 |
| Crown crack repair and coating | $650-$1,200 |
| Full crown rebuild | $1,800-$2,400 |
How long does a crown repair last in Cambridge?
A properly rebuilt concrete crown with waterproof coating lasts 15-20 years in Cambridge’s climate, though we recommend visual inspection every 2-3 years after year five. Call (508) 850-0489 for a free crown condition check.
Do I need separate caps for each apartment’s flue?
Yes, or one properly sized multi-flue cap with individual screening for each flue opening; shared openings create draft interference and code violations in multi-unit buildings. We measure and quote both options in writing before ordering materials.
Chimney Liner & Rebuild in Cambridge
Cambridge’s original clay tile liners are failing systematically after 100-plus freeze-thaw cycles and decades of heavy use from converted heating systems. We find cracked, shifted, or missing tile sections in roughly two-thirds of the unlined stacks we inspect in neighborhoods like Inman Square and Porter Square. A compromised liner allows exhaust gases to leak into wall cavities and neighboring units, which is why we treat every liner inspection as a multi-unit safety issue. Chimney Liner & Rebuild work is quoted with a written scope, written price, and written warranty before any demolition begins.
Stainless Steel Liner
Signs you need it
Clay tile fragments in the firebox, visible gaps or misalignment in the flue wall on camera inspection, or a failed Level 2 inspection for home sale or insurance renewal.
What it costs in Cambridge
Stainless steel liner installation in Cambridge ranges $2,800-$4,500 for a single flue, with multi-flue stacks running higher due to access complexity.
How we do it
We drop a video camera to map the full flue condition, remove damaged tile if necessary, and install a correctly sized stainless liner with proper insulation and top connections.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning or separated stack section, or mortar loss deep enough to expose the flue liner to weather.
What it costs in Cambridge
Partial rebuild of the upper stack in Cambridge typically runs $3,500-$6,500 depending on height, scaffolding needs, and whether the flue must be relined simultaneously.
How we do it
We scaffold to the work area, remove deteriorated courses to sound masonry, rebuild with matching brick and proper through-wall flashing, and document each layer photographically.
What Chimney Liner & Rebuild Costs in Cambridge
| Item | Typical range in Cambridge |
|---|---|
| Stainless steel liner (single flue) | $2,800-$4,500 |
| Flexible liner for offset flues | $3,200-$5,000 |
| Partial chimney rebuild | $3,500-$6,500 |
| Full chimney rebuild | $8,500-$15,000 |
Can a liner be installed without tearing down the chimney?
Yes, stainless and flexible liners are dropped down the existing flue from the top with minimal disruption; we only rebuild when the masonry shell itself has lost structural integrity. Call (508) 850-0489 for a camera inspection to determine which path applies.
How do I know if my clay liner is cracked behind a wood insert?
We remove or work around the insert and run the camera the full flue length; cracks hidden behind inserts are exactly what Haven Standard Clause 4 documentation is designed to catch and record.
Brands We Service in Cambridge
We stock caps, liners, and repair materials from DuraFlex, HeatShield, and Famco, with specialty orders from Copperfield and Olympia Chimney available through Haven’s buying network. Most standard parts arrive within 24-48 hours, keeping Cambridge jobs on schedule.
