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.
Trusted Chimney Repair for Boston Homeowners
Chimney repair in Boston typically costs between $400 and $4,800 depending on what’s actually wrong, and the honest answer is that you won’t know the real number until someone puts a camera down the flue. Since 2009, Level Two Chimney Boston has completed more than 38,000 inspections and repairs across Boston, Quincy, Cambridge, and the surrounding metro, and every single one started the same way: a written price before any work begins, backed by a documented photo record when it’s done. We don’t do flashlight estimates. We don’t sell repairs you can’t see. We show you the evidence, explain what it means in plain English, and hand you a written scope with a written warranty before a single brick gets touched. Call (857) 567-8887 and you’ll get a live person, 24/7.
What Our Chimney Repair Service Includes
Most chimney problems in Boston fall into six categories. Here’s what each one actually involves, when you need it, and what we do differently.
Mortar Repointing
Mortar Repointing is the process of removing deteriorated mortar from between bricks and replacing it with fresh material. In Boston’s freeze-thaw climate, mortar joints take a beating every winter: water seeps in, freezes, expands, and slowly crumbles the joint from the inside out. If you can scrape mortar out with a screwdriver, it’s time. We cut out the damaged joints to a proper depth and pack in new mortar matched to your chimney’s original color and hardness, so the repair doesn’t just hold, it disappears into the brickwork.

Spalling Brick Repair
Spalling Brick Repair addresses what happens when moisture trapped inside a brick freezes and pops the face off, leaving flaking, crumbled brick and a chimney that sheds pieces onto your roof or yard. Boston sees some of the worst spalling in New England because we cycle through freezing nights and thawing days all winter. We replace spalled bricks one at a time where possible, matching color, texture, and size from local Boston suppliers so the repair doesn’t look like a patch. Left alone, spalling progresses inward and can compromise the structural load of the chimney.

Chimney Waterproofing
Chimney waterproofing is a vapor-permeable sealant applied to the exterior masonry to stop water from soaking in while still letting moisture escape. This matters because trapped moisture is what causes most spalling, efflorescence, and interior water stains in the first place. A proper waterproofing job in Boston needs a siloxane or silane-based product, not a coat of paint, because paint seals moisture in and accelerates decay. We apply the right chemistry for your brick type and document the coverage with photos when we’re done.

Flashing Repair
Flashing is the metal seal where the chimney meets the roofline, and it’s the most common source of chimney leaks in Boston homes. Over time, flashing pulls away, corrodes, or was simply installed wrong from the start, letting water run straight down the chimney chase and into your attic or ceiling. We remove the old flashing, replace it with proper step and counter flashing, and seal it correctly rather than just caulking over the gap, which is what most quick-fix outfits do. A good flashing repair should last twenty years in Boston’s climate.

Chimney Rebuilding
A full rebuild is needed when deterioration has gone past the point where patching makes sense: the upper courses are loose, the crown is gone, or the chimney has begun to lean. We commonly rebuild from the roofline up or from the smoke chamber down, depending on where the damage stops. For Boston properties, a rebuild means matching the existing masonry profile, installing a new concrete crown, and ensuring the flue liner terminates correctly. It’s the most expensive repair, but done right, it’s a fifty-year fix, not a five-year band-aid.

Tuckpointing
Tuckpointing is commonly confused with repointing, but true tuckpointing is a finer craft: the joints are filled flush, then a thin contrasting line is cut into the mortar to replicate the look of original thin-joint brickwork. On older Boston brownstones and Victorians, proper tuckpointing preserves the architectural character that a standard repoint would erase. We have technicians who specialize in this work for historic homes in Cambridge and Boston’s older neighborhoods, and we document every course with photos so you can see the match before we finish.

Brands We Service for Chimney Repair

Level Two Chimney Boston installs and repairs liners and components from HeatShield, Gelco, and Olympia Chimney, three manufacturers we trust because their products hold up in New England’s freeze-thaw cycles. HeatShield’s cerfractory flue sealant system is something we use regularly for repairing cracked clay tile liners without a full liner replacement, a repair that saves Boston homeowners thousands compared to ripping out the old flue. We’ve applied the HeatShield system on hundreds of Boston-area chimneys and document the before and after with camera footage every time.
Gelco and Olympia Chimney supply the stainless steel liners, caps, and chase covers we spec for full liner replacements and rebuilds. We stock their components at our Boston shop, which means we’re not waiting on freight when your liner fails in November and you want heat before Thanksgiving. Whether you have a HeatShield-linered chimney, an older clay tile system, or anything else, we can diagnose it, repair it, and stand behind the work.

AfterSigns You Need Chimney Repair Right Now
- Water stains on the ceiling or walls near the chimney. This almost always means flashing failure or cracked crown mortar letting water in. The stain is the last symptom to show up; by the time you see it, water has been moving through the chase for a while.
- Crumbling mortar or brick pieces in the firebox or on the roof. That’s spalling and it’s progressive. Every freeze-thaw cycle in Boston pops more material loose, and the repair gets more expensive the longer it goes.
- White staining (efflorescence) on the exterior brick. Efflorescence is salt deposits left behind when water evaporates out of the brick. It means water is getting in, and it means the brick is slowly being turned into powder.
- A rusted or damaged damper that won’t open or close fully. This affects draft and can push smoke back into the house. It also often signals water damage in the smoke chamber above, which you can’t see without a camera.
- You smell damp, musty air coming from the fireplace in summer. That’s water sitting somewhere it shouldn’t be. In Boston’s humid summers, a damp flue liner is also a breeding ground for odors that push into your living space.
Our Chimney Repair Process - Step by Step

- 1
You call (857) 567-8887 and talk to a person. Not a voicemail, not a form. A live dispatcher answers 24/7, takes your address and the symptom, and books a window that works for you.
- 2
We inspect, we don’t guess. A background-checked, uniformed technician arrives with a camera system and runs an NFPA 211 Level 2 inspection. The camera goes down the flue, up the flue, and across the crown. You see everything on screen in real time.
- 3
You get a written price, written scope, and written warranty. Haven Standard Clause 1 requires this before any work begins. No ‘we’ll figure it out when we get in there.’ The price is the price.
- 4
We do the repair and document it. Photos before, during, and after. Camera footage of the finished flue. Clause 4 of the Haven Standard has required a documented photo record on every job since 2009, and we have the archive to prove it.
- 5
You get the record and the 365-Day Done Right Promise. If it’s not done right, we make it right. That’s stamped on every job under the Haven Standard.
How Much Does Chimney Repair Cost in Boston?
Here’s the honest breakdown of how much Chimney Repair costs in Boston right now. Mortar repointing typically runs $400 to $1,200 depending on how many courses are involved. Flashing repair usually falls between $500 and $1,800, with the higher end for complex rooflines or copper flashing. Spalling brick repair runs $600 to $2,500 depending on how many bricks need replacing and whether scaffolding is required. Chimney waterproofing is $400 to $900 for a standard single-flue chimney. A full rebuild from the roofline up runs $3,500 to $8,000 in Boston, and a liner replacement with HeatShield or stainless steel falls between $2,000 and $5,000 depending on flue height and access.
What changes the price: access difficulty (Boston rowhouses with shared party walls cost more than freestanding suburban chimneys), material condition, flue height, and whether the damage extends below the roofline. The way to avoid overpaying is to get a camera inspection before you get a quote. If a contractor gives you a repair number without putting a camera down the flue, that number is a guess. Our estimates are free, written, and based on what we can show you. Bring us a competitor’s written estimate and we’ll give you a free second opinion on it.

Frequently Asked Questions - Chimney Repair in Boston

Chimney repair is any corrective work on the masonry, liner, flashing, crown, or damper system that restores the chimney to safe, functional condition. In Boston, the most common repairs are mortar repointing, flashing replacement, spalling brick replacement, and liner repair. At Level Two Chimney Boston, every repair starts with a camera inspection so you’re fixing what’s actually wrong, not what a salesman guessed. Call (857) 567-8887 for a written estimate.
Most mortar repointing and flashing repairs in Boston are completed in one day. Spalling brick replacement usually takes one to two days, and a full chimney rebuild runs three to five working days depending on weather access. We give you a written timeline with your written price, and that timeline includes weather buffer for Boston’s unpredictable conditions. Same-day inspection appointments are usually available.
Chimney repair in Boston runs from $400 for minor repointing up to $8,000 for a full rebuild. The average repair ticket across our Boston service area falls between $800 and $1,800, which usually covers flashing replacement or mid-scale brick and mortar work. The only way to get a real number for your chimney is a camera inspection, which we do for free as part of every estimate. Call (857) 567-8887 and we’ll give you the written price before anything starts.
Yes. We work on masonry chimneys, prefab metal chimneys, and historic brick chimneys across Boston, Cambridge, and the surrounding towns. Our technicians are experienced with the full range: clay tile liners, stainless steel liners, cast-in-place systems, and multi-flue commercial stacks. If you’re not sure what you have, the camera inspection tells us and you can watch the whole thing live.
Some repair is urgent and some can wait, and the difference is visible on camera. A cracked liner or failed flashing that’s actively leaking water needs attention before the next freeze-thaw cycle. Spalling brick that’s purely cosmetic on the exterior face may hold for a season. What we won’t do is tell you something is urgent when it isn’t, or tell you something can wait when it can’t. You’ll see the evidence and we’ll give you a straight answer.
Every chimney repair from Level Two Chimney Boston includes a written warranty with the specific coverage terms spelled out before we start. On top of that, the 365-Day Done Right Promise applies to every job: if it’s not done right, we make it right. That promise is stamped on your job under the Haven Standard, and it’s been the rule since 2009.
You don’t need to do much. Clear a path to the fireplace, move anything fragile off the mantel, and make sure we can access the roof if the repair is exterior. We bring drop cloths, we protect the work area, and we document everything with photos before we start so your home is exactly as we found it when we leave. If roof access requires a ladder over a garden or careful footing on a Boston rowhouse, we handle it.
