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.

AfterFast, Reliable Chimney Repair Across Boston
Chimney repair in Boston typically costs $650-$4,500 depending on scope, with mortar repointing starting around $850 and full rebuilds reaching the upper end for triple-deckers and historic row houses. Most inspections are scheduled within 3-5 business days, and our Chimney Repair in Boston crews dispatch from our local metro office to cover Dorchester, South Boston, Jamaica Plain, Beacon Hill, and surrounding neighborhoods.
Boston’s coastal position creates chimney problems you won’t find inland. Salt-laden air corrodes galvanized caps and flashing in half the time it takes in Worcester, while nor’easters drive freeze-thaw cycles that exploit every hairline crack. We’ve completed more than 38,000 Chimney Cleaning & Sweep in Boston inspections since 2009, and the Boston jobs that escalate to full rebuilds almost always started as minor crown damage that went unaddressed before winter. If you’re seeing brick flakes in your yard, rust stains on the firebox, or a damper that won’t open smoothly, call (508) 850-0489. We’ll send a written price before any work starts, and every visit includes a camera-scan inspection with a documented photo record under Haven Standard Clause 4.
Why Level Two Chimney Framingham Is Boston’s Preferred Chimney Repair Company
Our reputation in Boston was built on documentation, not promises. Every job gets a written price, written scope, and written warranty before anyone touches your chimney - Haven Standard Clause 1, H.A.V.E.N. “Have it in writing.” Homeowners in triple-deckers from Columbia Road to Blue Hill Avenue know this matters because they’re coordinating repairs across three households, not one.
We answer our phones live, 24 hours a day, 7 days a week. No voicemail, no web form. When you book in Boston, you get a background-checked, uniformed technician with a license number on the page, a named tech assigned, and a text when they’re on the way - H.A.V.E.N. “Arrive on schedule” and “Verified crews.”
The 365-Day Done Right Promise backs every repair: if it’s not done right, we make it right. And our Free Second Opinion on Any Written Estimate means you can bring us a competitor’s quote for chimney rebuilding in Roxbury or flashing repair in Back Bay and we’ll review it against what our camera found.
Our Boston-area customers are homeowners aged 32-50 who bought between 2015 and 2025 and read the three-star reviews before calling. They want photos, readings, and a written record - which is exactly what Clause 4 of the Haven Standard delivers on every visit.
Our Chimney Repair Services in Boston
Mortar Repointing
Repointing in Boston runs $850-$2,200 for a typical triple-decker chimney, more for brownstones in Beacon Hill where matching historic mortar color requires custom mixes reviewed by the Boston Landmarks Commission. We grind out failed joints to proper depth, match the original mortar composition, and document before-and-after photos under Haven Standard Clause 4. In South Boston and Dorchester, we repoint chimneys where salt air has accelerated joint deterioration beyond what the calendar would suggest.
Spalling Brick Repair
Spalling - brick faces popping off from freeze-thaw damage - starts at $1,200 for localized repair and can reach $3,800 if the chimney stack requires partial rebuild. Boston’s nor’easters are the culprit: water enters hairline cracks, freezes overnight, and exfoliates the brick surface. We see this most on triple-decker chimneys in Jamaica Plain and Roxbury where original 1920s brick has endured a century of coastal winters. Our Chimney Repair team sources replacement brick through Haven’s buying network to keep prices honest.
Chimney Waterproofing
Waterproofing a Boston chimney costs $400-$950 depending on surface area and accessibility, with breathable silane-based sealants that let moisture escape while blocking salt-laden rain. This is essential preventive work. We’ve waterproofed chimneys in Dorchester that would have needed full rebuilds within three years without it. The treatment includes a camera inspection to confirm no active leaks are being sealed inside, and we warranty the application for five years.
Flashing Repair
Flashing repair in Boston ranges from $350 for simple counter-flashing replacement to $1,800 where step flashing must be removed and reinstalled during roof work. Salt air destroys galvanized flashing here; we use stainless steel or copper as the practical default, procured through Copperfield and Famco. In Back Bay and the South End, where flat roofs meet masonry chimneys at odd angles, custom-fabricated flashing is often required. We photograph the existing condition, show you the rust patterns our camera found, and quote in writing before cutting metal.
Chimney Rebuilding
Full or partial chimney rebuilding in Boston starts at $3,500 and ranges to $8,500+ for triple-decker stacks requiring scaffolding and tenant coordination across three units. We rebuild with materials from DuraFlex and Olympia Chimney, sourced through Haven’s network. Every rebuild includes a new stainless steel cap, proper crown slope with drip edge, and documentation of flue liner condition before we close the masonry. In Beacon Hill and Back Bay, we coordinate Boston Landmarks Commission review as part of our scope - not as a surprise add-on.
Tuckpointing
Tuckpointing - the decorative or structural replacement of mortar to match original fine-line joints - runs $1,100-$2,800 in Boston. Historic row houses in Beacon Hill often need this where previous owners used Portland cement patches that trap moisture and accelerate spalling. We remove incompatible mortar and replace with lime-based mixes that move with the masonry, then document the work with dated photos for your records and any future LMC review.

AfterTrusted Brands We Service in Boston
We stock and install materials from DuraFlex, HeatShield, and Copperfield, procured through Haven’s buying network specifically to keep Boston customer prices honest. DuraFlex liners handle the multi-flue configurations common in triple-deckers; HeatShield’s cerfractory coating restores eroded smoke chambers without full rebuild; Copperfield supplies the stainless steel caps and custom flashing that outlast galvanized alternatives in salt air. Because we maintain local inventory, turnaround on standard repairs in Dorchester, South Boston, and Jamaica Plain runs days, not weeks. For Beacon Hill jobs requiring Landmarks Commission review, we submit material specifications with the permit package so approval isn’t delayed by product questions.
Common Chimney Repair Problems We See in Boston Homes
- Galvanized caps rusted through from salt air. We replace these with stainless steel models on nearly every Boston repair call. A rusted cap lets rainwater into the smoke chamber, corroding the damper and staining the firebox - damage that adds $400-$900 to the repair if caught late.
- Freeze-thaw spalling on triple-decker stacks. Nor’easter cycles turn minor crown cracks into brick loss over a single winter. Annual inspection catches this before rebuild territory; biennial scheduling often misses the window in Boston’s climate.
- Original unlined brick flues in pre-1930 housing. These allow creosote to penetrate masonry, creating hidden fire risk and carbon monoxide migration between units. Only a Level 2 camera inspection reveals the condition; a flashlight look from the top won’t see it.
- Failed flashing at flat-roof junctions in Back Bay and South End. The combination of low-slope roofing, heavy snow load, and salt corrosion creates leak paths that rot roof decking before interior stains appear. We find these with camera inspection of the chimney exterior from the roof level.

FAQs - Chimney Repair in Boston
Galvanized steel caps corrode in 3-5 years in Boston’s salt-laden coastal air, whereas stainless steel lasts 15-20 years. The salt accelerates rust so aggressively that we consider galvanized caps a false economy here; the replacement cap, damper repair, and smoke chamber damage from the leak typically cost $1,200-$2,400 by the time a homeowner notices the problem. Call (508) 850-0489 for an exact quote - estimates are free.
Annually. Boston’s salt air and freeze-thaw cycling justify annual inspection for any chimney, but triple-deckers carry stacked flues serving three separate households - so creosote buildup or a cracked liner on one level creates carbon monoxide and fire risk for every unit. Coordinating tenant access takes planning; we schedule multi-unit inspections with a single appointment window and deliver separate photo records for each flue under Haven Standard Clause 4. Call (508) 850-0489 to book.
Yes. Beacon Hill is a National Historic Landmark District, and any exterior chimney repair, repointing, or rebuilding requires review by the Boston Landmarks Commission - a permitting layer that does not apply to identical work across the city line in Brookline or Cambridge. This review can add 2-4 weeks to project timeline, which is why we submit material specifications and scope documentation with the initial application. We handle this coordination as part of our standard scope for Beacon Hill and Back Bay properties. Call (508) 850-0489 to discuss your project timeline.
Freeze-thaw cycling from nor’easters is the primary cause: water enters mortar joints or crown cracks, expands when frozen, and pops off brick faces. Boston’s coastal position makes this worse because salt-laden air draws more moisture into the masonry, and the temperature swings between nor’easter events are sharper than inland. Spalling starts as surface flaking and progresses to structural brick loss; annual inspection catches it at the $1,200 repair stage rather than the $6,500 rebuild stage. Call (508) 850-0489 for a free inspection.
Yes. A single brick chimney on a triple-decker typically carries stacked flues serving all three units, so a cracked liner in the second-floor flue can leak carbon monoxide into the third-floor smoke chamber or allow chimney fire spread between units. Only an NFPA 211 Level 2 camera inspection of every flue can verify separation and integrity; our techs coordinate with all tenants to access each unit during the same visit. We document every flue separately under Haven Standard Clause 4. Call (508) 850-0489 to schedule multi-unit access.
Schedule Your Boston Chimney Repair
We were called to a triple-decker on Columbia Road in Dorchester after a tenant reported a draft that smelled like tar. Our tech found first-degree creosote in the flue serving the first-floor unit and a rusted-through galvanized cap that had let rainwater into the smoke chamber, corroding the damper. We replaced the cap with a stainless steel model, repointed the crown, and installed a HeatShield liner in the damaged flue; the annual inspection now catches salt corrosion before it reaches the firebox.
