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.

Most repairs in Somerville are quote-ready in one visit because we bring cameras and write the price before any work starts.

Somerville’s housing stock is different from the suburbs. We’re working on pre-1940 two- and three-family homes from Davis Square to Winter Hill, and that changes what we look for: shared chimney stacks, multiple flues in one masonry column, and decades of deferred repairs. We know which blocks have the roughest free-thaw exposure, and we scope repairs accordingly. No guesswork. No moving the number at the door.
Why Flint Chimney Sweep Is Somerville’s Preferred Chimney Repair Company
Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and the operating rules haven’t changed since. Every repair gets a written price before work begins. Every repair carries a 365-Day Done Right Promise in writing, valid for a full year. If a covered repair fails, we return at no charge. That’s the Garrison Standard, and it applies on every job we run in Somerville.
Technicians sent to Somerville are background-checked and uniformed. You’ll know who’s at your door before they knock. Dispatch and scheduling run through our Boston office, so response times to Somerville neighborhoods are consistent. We’re not a subcontractor network. The person on your roof is a Flint employee, trained on the same inspection and repair protocols across the Garrison Partners family.
Somerville homeowners call us because they’ve been burned by companies that quote one number on the phone and another on the porch. That doesn’t happen here. The invoice matches the approved scope. Period. Hank Delano runs Flint Chimney Sweep with that rule at the center of every job, and Somerville customers in East Somerville, Teele Square, and Ball Square keep calling back because of it.
Chimney Masonry Repair in Somerville
Chimney Masonry Repair is the umbrella term for the structural work that keeps Somerville’s older chimneys standing: repointing failed mortar joints (tuckpointing), rebuilding spalled brick, and repairing or replacing the crown that sits on top of the stack. In Somerville, we see this work most often on triple-deckers and century-old single-families where freeze-thaw cycles have eaten the top courses of brick above the roofline. A typical masonry repointing job in Somerville runs $350 – $850 depending on access and how many courses need work. Crown rebuilds run $400 – $900.
The masonry side is where Somerville homeowners get sideways with lesser companies. A brush-and-vac cleaning won’t flag a cracked crown or a failing mortar joint. Our techs run a camera inspection on every repair call, and you get a photo report showing exactly what’s failing. If the masonry can wait, we tell you it can wait. We’ve walked away from jobs other companies would have sold.
Spalling Brick and Mortar Repointing
Spalling means the brick face is flaking off, usually from water that soaked into the brick and froze. On Somerville’s older stacks, the top courses take the heaviest beating because they’re fully exposed to winter storms off the Atlantic. Repointing (removing and replacing failed mortar) stops the water from getting further into the stack. Left alone, spalled brick lets water into the smoke chamber and eventually into wall cavities behind interior plaster.
Crown Repair and Chimney Waterproofing
The crown is the concrete or mortar cap on top of the chimney that sheds water off the stack. Somerville’s freeze-thaw cycles crack crowns within a decade or two of install, and once water gets into the smoke chamber, the damage compounds fast. We rebuild crowns with proper overhangs and bond breaks, then waterproof the exterior brick with a vapor-permeable sealer. Chimney waterproofing in Somerville typically runs $300 – $600 for a standard single-family stack.
Chimney Cap Installation in Somerville
Chimney Cap Installation in Somerville is one of the more straightforward repairs we do: a cap covers the opening of the flue to keep out rain, snow, leaves, and animals while letting smoke and gases vent. In Somerville, caps are especially important on multi-family stacks because each flue needs its own cap. A rusted cap a few years old is a sign someone installed cheap material. We stock caps from Copperfield and Famco, and installation in Somerville typically runs $240 – $520 including the cap itself.
The cap also matters for draft. If the cap is too small or clogged with creosote or nesting material, the flue won’t pull properly and smoke backs up into the room. That’s a common call from Somerville triple-decker owners who smell smoke in one unit but not the others. Cap plus a proper camera inspection clears the question fast.
Multi-Flue Caps for Triple-Deckers
Somerville’s two- and three-families often have one masonry stack with two or three flues inside it. Each flue serves a different heating unit or fireplace, and each flue needs its own cap or a single multi-flue cap sized to the whole stack. If one flue is uncapped and birds or rain get in, the unit it serves may experience poor draft even if the other flues are fine. We spec multi-flue caps from Copperfield and install them with the right spacing so every flue breathes.
When a Cap Can Wait
Not every rusted cap needs immediate replacement. If the cap is intact enough to keep out rain and debris, a cleaning and a camera look may buy you another season. We’ll show you the photos and give you a straight answer. If the cap is sagging or the mesh is gone, animals can get in, and that becomes a real problem. Bats and squirrels nesting in a Somerville flue will block draft and can die in the stack.
Trusted Brands We Service in Somerville
We use professional-grade materials from trade brands you can verify yourself. DuraFlex and HeatShield for flue liners, Copperfield and Famco for caps, and Gelco and Olympia Chimney for waterproofing and repair products. We stock common cap sizes and liner components in our Boston facility so most Somerville repairs don’t sit waiting on parts. When your Somerville chimney needs a brand we trust, we install it and stand behind it in writing for a year.
If you need a Chimney Repair quote, we’ll specify the brands on the written estimate before you approve anything. No generic “chimney parts” at whatever the supply house had that week. The material is chosen for the job, not the margin.
Common Chimney Repair Problems We See in Somerville Homes
- Shared stacks patched flue-by-flue. Somerville triple-deckers often have multiple flues in one masonry column, and when one flue liner fails, the other flues still draft fine. That masks the problem until carbon monoxide backs up into one unit. The only way to catch it is a Level 2 camera inspection that actually sees inside each flue, not just the one serving the unit that called us.
- Freeze-thaw damage on the top courses. Somerville winters turn water into ice inside cracked mortar joints, and the top two or three courses of brick above the roofline take the worst of it. Spalled brick faces and cracked crowns are the normal result. A cleaning won’t flag it; a masonry repair will.
- Seized or rusted dampers in pre-war fireboxes. In Somerville’s older homes, the original cast-iron damper plate often rusts open or seizes shut. The fireplace may not even be used by the current tenant. A homeowner pays for a cleaning when the actual repair is a new damper and a cracked firebox that needs repointing.
- Second- and third-degree creosote in the smoke chamber. Burn cycles in older Somerville fireplaces and oil-fired furnaces leave creosote crusts that a brush won’t remove. This is a fire hazard. Proper removal means access to the smoke chamber, and that’s why we scope repair and cleaning together instead of selling one without looking at the other.

Somerville has one of the highest concentrations of pre-1940 two- and three-family triple-deckers in the country. That means we regularly inspect shared chimney stacks serving multiple heating systems in one building, a condition that changes how we scope flue liner and masonry repair. A single-family home with one flue is a different job than a three-flue stack on a Highland Ave triple-decker. We do the camera work and photo report to show you which flues are sound and which ones are failing, and we don’t sell work that can wait. If you own or manage a Somerville multi-family, this is the reason you want a Chimney Repair in Somerville company that understands shared stacks, not just sweeping.

FAQs About Chimney Repair in Somerville
Yes, and the reason is that the chimney stack is shared even if the fireplaces aren’t. The flue serving your unused fireplace runs through the same masonry column as the flue serving the furnace in the unit below. A failing flue liner, cracked crown, or animal nest in one flue can back carbon monoxide into a unit even if that unit’s fireplace was never lit. We inspect every flue in the stack with a camera, not just the one that gets used. Call (830) 251-4560 and we’ll send the photo report to whoever manages the building.
If you see water stains on the ceiling near the chimney, spalled brick on the top courses, or a rusted cap, that’s repair territory, not a cleaning. A cleaning removes creosote and soot; it doesn’t fix masonry. The defining test is a Chimney Inspection - Somerville. We run the camera through every flue, photograph the smoke chamber, and hand you the photos. If the liner is intact, the crown is sound, and the damper works, a cleaning is probably all you need. If the photos show cracks, spalling, or missing cap mesh, we’ll put the repair price in writing before you decide anything.
Third-degree creosote is a hard, glossy, tar-like crust that forms when the flue stays hot and the creosote concentrates. It looks like black glass or hardened road tar stuck to the flue wall. No, a standard chimney brush won’t take it off. The brush skips over the surface and leaves the fire hazard in place. Removing third-degree creosote requires chemical treatment or mechanical removal with specialized tools, and in Somerville older flues we often pair that with a camera inspection to check for liner damage underneath. If you haven’t had the flue looked at in years, call (830) 251-4560 and we’ll tell you what’s actually in there.
Usually yes, and the reason is that the crown and the cap do the same job: keep water out of the flue. If the crown is cracked and spalled, water gets into the masonry around the flue. If the cap is rusted through, water gets directly into the flue. Fixing one without the other leaves the chimney half-protected. In Somerville’s freeze-thaw climate, a half-protected chimney fails again within a season or two. We’ll quote both repairs on one written estimate so you can see the cost of doing it correctly the first time.
We’ll give you a written price before any work starts, but we don’t quote sight-unseen over the phone. The honest answer is that a chimney repair price depends on access, the condition of the flue liner, and how many courses of brick are actually failing. What we will do is come to your Somerville property for a free estimate, run the camera, and hand you a written price that covers the exact scope of work. That price is the price. Nobody adds a line item at the end. Call (830) 251-4560 and Hank Delano will make sure the estimate is straight.
