From down at the hearth a chimney hides nearly everything that matters about its real condition, which is exactly why a proper inspection is worth the money. It swaps a guess for hard evidence. Cambridge Chimney Sweep inspects chimneys across the city whether you are buying or selling a home, adding or swapping an appliance, recovering from a chimney fire, or simply want the assurance that the flue is safe to light this winter. You get a careful examination of the whole chimney system, a camera run up the flue where access allows, photographs of anything we turn up, and a clear written report graded against the NFPA 211 levels, with nobody leaning on you to buy a thing afterward.

- Draft and clearance to combustibles verified

- No obligation, nothing tacked on at the end
Matching the inspection level to your situation
Chimney inspections come in three recognized levels, and choosing the right one for your circumstances is the first responsibility of an honest inspector. A Level 1 inspection is the routine yearly check for a chimney that has not changed and is being burned the same way as before. We go over the readily reachable parts inside and out, confirm the flue is clear and the structure is sound, and verify there are no obvious hazards. For most Cambridge homeowners staying on top of annual maintenance on an unchanged system, that is the right inspection and a sufficient one.
A Level 2 inspection reaches further and is the right call whenever something has changed or more certainty is needed, such as a home sale, a new or different appliance, a change of fuel, or the aftermath of an event like a chimney fire. It adds a video scan of the entire flue interior so we can see the liner along its full length, the joints between tile sections, and any cracking a Level 1 look from the ends would miss. A Level 3 inspection, the most intrusive, is held in reserve for cases where a serious hazard is suspected and confirming it means opening part of the structure. We tell you at the outset which level your situation honestly calls for, and why, rather than reaching by default for the priciest one.
What the camera catches that no eye ever will
The most valuable instrument in any modern chimney inspection is the camera, for the simple reason that the part of the chimney most likely to be quietly failing is the part no one can lay eyes on. The clay flue tiles in so many of Cambridge's older homes were a fine choice in their day, but decades of heat cycling, the odd chimney fire, and the slow shifting of settling masonry crack them, and a cracked or gapped liner is a straight path for heat and combustion gases to reach the wood framing packed tight around the flue. From the firebox you might see a clean, perfectly ordinary opening while a tile twenty feet overhead is split far enough to be a real fire hazard. Running a camera the whole length of the flue is the only honest way to know.
On the many Cambridge homes built with shared chimney stacks and several flues in one structure, the camera proves its worth again, because it confirms which flue serves which appliance, whether one flue is bleeding into another where the dividing mortar has failed, and whether an old abandoned flue is admitting moisture or animals into the system. We record the scan, walk you through the footage on the spot, and write what it shows into the report. You are never asked to take our word for a hidden crack. You see it on the screen, and the evidence is yours to keep.
A report you can act on and hold onto
An inspection is only ever as good as the honesty and the clarity behind it. Our report states plainly what is safe to burn as it stands, what wants attention before the next fire, and what can reasonably wait and simply be watched. If the chimney is in good shape, that is exactly what you will hear, because telling a homeowner the flue is sound and a sweep is all it needs is how we earn the call when a genuine repair finally comes due. We do not invent urgency, and we never recommend a thing the photographs and the camera footage cannot support.
The report and the images belong to you no matter what you decide, which matters most of all in a home sale, where a documented chimney inspection settles a question that buyer and seller would otherwise be left guessing about. You are welcome to set our assessment beside anyone else's. That openness is the entire point. A homeowner who can study the evidence makes a sounder decision, and a chimney company that invites that kind of scrutiny is usually the one worth hiring. If your chimney has gone more than a year without a look, or you are about to light a fireplace you inherited along with the house, an inspection is the cheapest certainty you can buy.
