There is no part of an old Cambridge house that works harder or gets checked less than the chimney. Stand on almost any block off Massachusetts Avenue, between the Federal-era homes near Harvard Yard, the packed three-deckers of Cambridgeport and Riverside, and the streets of academic housing out toward Huron Village, and you are looking at masonry that was laid generations ago, with clay flue tiles set long before a furnace or a gas insert was ever bolted to them. Every long Massachusetts winter asks that old structure to carry the exhaust of a wood fire or a modern appliance safely up and out, and the two things that quietly defeat it are the same two things we are in business to stop: a season's worth of creosote glazing the inside of the flue, and the endless freeze-and-thaw that splits brick and crown apart from the outside in.

Cambridge Chimney Sweep does this work and only this work. We clear the soot and creosote that a winter of burning leaves caked on the tile, we send a camera the length of the liner and hand you a plain report on what it actually found, we rebuild crowns and reseal the flashing where the stack meets the roof, we repoint the mortar joints that have weathered open, we fit caps that shut out rain and the squirrels of every Cambridge backyard, and we drop in correctly sized liners that make a tired old flue safe for whatever it now vents. Dial 617-221-4253 and a person answers, and when we open your firebox and put a light up the throat, you are looking at the very same chimney we are.

We open every job the same way, with a careful look and a straight answer rather than a sales script. Now and then the answer is the easy one, a routine sweep and a sound liner, and the chimney is good to burn for another year. Other times it is the harder news, a flue tile cracked open well above the smoke chamber, or a crown that has been feeding rainwater into the brick for a few seasons without anyone knowing. Either way you get the facts, photographs of what we saw, and a written number, and you make the call on your own clock. Nothing on a Cambridge Chimney Sweep estimate is invented to frighten you into hiring us.

About Cambridge Chimney Sweep

Cambridge Chimney Sweep is a local chimney company working Cambridge and the towns immediately around it. We are sweeps and brick masons in the everyday meaning of those words. We clean, inspect, repair, reline, cap, and rebuild chimneys, and our own people do the work rather than a rotating cast of subcontractors you never meet twice. We hold ourselves to the standards the trade runs on, the NFPA 211 inspection levels and the published specifications of the appliances and liner systems we install, so that when we sign off on a chimney, we are signing off on one that keeps fire and combustion gases where they are supposed to stay.

In practice that means we treat your chimney as a single connected structure, not a checklist of unrelated parts. The firebox, the smoke chamber, the flue and its liner, the crown, the cap, the flashing, and the brick shell all lean on one another, and a company that runs a brush down the flue without ever glancing at the crown or scanning the liner has left the real danger exactly where it was. We read the whole thing top to bottom, we explain what we find in language a homeowner can follow, and we quote only the work the chimney genuinely needs, never a line item added to round up the bill.

What a Cambridge heating season does to a chimney

A New England winter shows a chimney no mercy, and Cambridge gets the full version of it. The cold stretches on for months, households here burn through it hard, and a flue that might sit idle most of the year in a milder place runs steadily from the first frosty weekend until the thaw finally arrives. Every fire that burns cool or sluggish, and the older, slow-drafting flues so common in this city rarely burn anything but cool, lays down a film of creosote on the inner wall of the liner. That sticky residue is the worst single hazard a chimney holds, because it is unburned fuel sitting inside the passage that carries the fire's heat, and once it has stacked up thick enough an overfired stove or a stray ember can touch it off and send flame roaring the full height of the flue. Hard, regular winter use is precisely why skipping the yearly sweep is a gamble no Cambridge homeowner should take.

Water does the slower, sneakier damage, and on Cambridge brick it never lets up. Rain and melting snow soak into the porous brick, the mortar joints, and the concrete crown, and then the mercury drops and the trapped moisture freezes and swells. Run that cycle through one Cambridge winter and it flakes the faces off bricks, hollows out the mortar, and splits the crown wide, and every fresh opening simply invites in more water to freeze again come the next cold snap. The chimney that springs a leak in early spring was very often nothing but a hairline crack in the crown the previous autumn. That is why we push so hard to catch masonry trouble while it is small, when a modest repointing job will still spare you the cost of a rebuild.

All of it handled with one phone call

Most people in Cambridge would far rather make a single call than chase down a separate sweep, a mason, and a liner crew and try to get the three to coordinate. Cambridge Chimney Sweep is set up to be that one call. We do the yearly cleaning that pulls out creosote and soot, the camera inspection that tells you the true state of the flue, the repairs that put a leaking crown or a frozen damper right again, the caps that keep the weather and the wildlife out of the throat, the liner replacements that bring an old chimney up to a safe modern standard, and the brick and mortar work that restores spalled faces and crumbling joints before the structure starts to lean.

Because one crew handles the whole list, nothing gets lost in the handoff between trades. The same technician who sweeps and scans your flue is the one who measures the repair, so the liner ends up sized to the appliance it really serves and the cap fits the flue it actually sits on, instead of being ordered sight unseen by someone who never climbed your roof. One company, one standard, one name on the hook for the work from the first inspection through the last sweep of the hearth.

Documented findings, a written price, and no fear-mongering

A chimney inspection ought to be an honest safety check, not a pitch in coveralls. When we inspect a Cambridge chimney we photograph it and, wherever the flue allows, run a video camera up it, then walk you through the images and tell you plainly whether you are looking at a simple sweep, a focused repair, or a chimney that is perfectly fine and just wants its annual cleaning. If a small fix will carry you safely through several more winters, that is what we will say, even when the larger job would mean a larger invoice for us. The honest read is what brings the next call and the recommendation to the neighbor down the street, and that long game is the only way we know how to run this.

Once you know what the chimney needs, you get a written estimate that spells out the scope and the materials. The figure you sign off on is the figure you pay, unless you ask for a genuine change or we uncover something hidden behind the brick once we have opened it up, which we would always photograph and talk through with you before going any further. When the work is finished we leave the firebox and the room cleaner than we found them, show you the before-and-after images, and put our workmanship in writing.

Our Cambridge crew handles the full chimney: flue cleaning to clear creosote, chimney camera scan to document what is really up the flue, chimney patching when the crown or flashing fails, chimney cap installation to keep out water and animals, flue relining to make the flue safe again, and tuckpointing for the brick and mortar.

Beyond Cambridge itself, we cover the surrounding area, including chimney sweep in Somerville, our Arlington sweeps, Belmont, MA, Watertown chimney sweep. If you searched for a local chimney crew near you, you have reached the crew that does the work itself.

Straight Fireplace and Chimney Questions

How to make a chimney cap?

People ask how to handle this themselves, and the real steps involve more skill and safety gear than a video suggests. Store-bought kits handle the easy, visible part and miss the glazed buildup and the cracks higher up. We do this from the roof with the right setup, and we inspect the whole top of the chimney while we are up there. Phone 617-221-4253 and a real person will book you.

How do you repair chimney crown?

The honest answer is that most of this work is skilled, and often rooftop, work. Getting the sizing, the fastening, or the sequence wrong is exactly where amateur attempts go wrong. We are glad to tell you honestly what you can watch for yourself and what is worth leaving to us. Call 617-221-4253 for honest, local help.

What does a chimney cap look like?

Here is what a chimney cap actually is and why it matters. When it fails, the problem is usually hidden until a leak, a draft issue, or a smell gives it away. The honest way to know its state is a real inspection, not a guess from the hearth. Phone 617-221-4253 for an honest look.

How much is a chimney inspection?

The number for a chimney inspection depends on the flue, the access, and how far any wear has gone. The material, the appliance, and the state of the crown and masonry all move the figure. We do not quote it over the phone; we look, then quote it in writing with no bait pricing. Phone 617-221-4253 and a real person will book the estimate.

How do you cap off a chimney?

You can attempt this yourself, but doing it well is harder and more dangerous than it looks. Much of the risk is the roof, since chimney tops sit at the highest, most exposed point of the house. If you want it done once and done right, it is worth having a crew that does it daily handle it. Call 617-221-4253 and we will handle it from the roof.

How much does it cost to repair a chimney?

Pricing chimney repair honestly means pricing it from the real condition, not a flat menu. A routine sweep is one number, and a repair, a reline, or masonry work is another, so the scope drives the total. We scan the flue, assess the masonry, and lay out the full scope in writing up front. Call 617-221-4253 and we will inspect it and quote it in writing.
