TopDog Chimney serves homeowners across Cambridge with chimney sweeping, Level 1 and Level 2 inspections, and the repairs that sometimes follow.
Whether you own a triple-decker, a brick rowhouse, or a single-family Colonial Revival, we start with what your chimney is actually doing.
Most chimney problems hide above the roofline or inside the flue. A thorough inspection turns guesswork into a clear list of what is fine, what can wait, and what needs attention.

Cambridge was one of the New England cities that built thousands of triple-deckers, and it sits alongside brick rowhouses, Colonial Revivals near Brattle Street, and newer condos. That mix means chimneys of very different ages, often on tight lots where rooflines run close together.
In multi-unit buildings, one stack may carry several flues, so it matters to know which appliance vents where and whether each flue is in good shape. Many older flues were built for coal or wood and now serve a gas furnace or water heater, which puts different demands on the liner. Our chimney liner installation page explains why that match matters.
Some Cambridge streets also fall inside historic or neighborhood conservation districts. If your plans include visible exterior work, it is worth checking with the Cambridge Historical Commission first.
A Level 1 inspection covers the accessible parts of the chimney and fireplace, and it is part of every sweep we do. A Level 2 inspection adds a camera scan of the flue, showing cracks, gaps, and deposits a flashlight cannot reach.
NFPA 211, the national chimney standard, calls for a Level 2 inspection in specific situations: buying or selling a home, changing your appliance or fuel, adding or replacing a liner, or after an event such as a chimney fire or a strong storm. For Cambridge buyers and sellers, a Level 2 chimney inspection gives both sides a documented picture of the flue before closing.
Every wood fire leaves soot and creosote behind, and the deposits build with routine use. Our chimney cleaning and Level 1 inspection service starts with drop cloths and a HEPA vacuum, then a full flue sweep, and ends with a written report with photos.
Cleanliness matters in Cambridge apartments and condos, where you rarely have a spare room to shut off. If you want to understand why buildup deserves attention, our guide to creosote buildup and chimney fire risk explains it plainly.
A sweep is usually the answer when the fireplace works normally, and you simply want deposits removed. An inspection makes sense when something has changed: a new appliance, a new home, a smell, staining, or a storm. Repairs follow when the inspection finds damage such as failing mortar, a cracked crown, or a deteriorated liner.
Our article on what we look for during a Massachusetts chimney inspection walks through the checklist, and five signs your chimney needs a professional inspection covers the warning signs homeowners can spot themselves.
Brick and mortar absorb water, and when that water freezes, it expands. Repeated freeze-thaw cycles widen small cracks in mortar joints and crowns until moisture reaches the masonry interior. Missing caps and flashing problems make it worse.
Not every ceiling stain means the chimney is leaking, since roofs and plumbing vents can cause similar signs. An inspection helps sort out the real source.
| Service | Common Reason to Schedule | Main Goal |
| Chimney sweep and Level 1 inspection | Soot, creosote, or yearly maintenance | Remove deposits and check accessible parts |
| Level 2 inspection | Home sale, new appliance, or storm | Evaluate the flue with a camera |
| Chimney repointing | Crumbling or missing mortar joints | Restore joints before water damage spreads |
| Crown repair | Cracks across the top of the chimney | Reduce water entering the masonry |
| Smoke chamber repair | Rough or deteriorated chamber walls | Improve draft and protect surrounding framing |
Beyond inspections, we handle chimney repointing,crown repair,smoke chamber repair, and cap installation and waterproofing for rooflines that take the brunt of the weather. For a look at interior work, see our smoke chamber parging project.
Describe what you are noticing, and we will point you toward a sweep, an inspection, or a repair estimate. Many Cambridge calls start with a smell or a stain and turn out to be something simpler, or something worth catching early.

The National Fire Protection Association (NFPA 211) recommends inspecting all chimneys, flues, and vents at least once a year and cleaning whenever there is 1/8 inch or more of creosote buildup. In Cambridge, where many historic and multi-family homes rely on fireplace or wood stove heat throughout long New England winters, annual chimney maintenance ensures safe venting, prevents chimney fires, a
Yes! Even though gas burns cleaner than wood and doesn’t produce creosote, gas appliances generate acidic condensation as exhaust vents. Over time, acidic flue gas breaks down clay flue liners and mortar joints, creating dangerous carbon monoxide pathways into your living quarters. Birds, squirrels, leaves, and debris can also easily clog gas flues, causing toxic carbon monoxide to back up into yo
Yes. Massachusetts real estate transactions strongly recommend a Level 2 chimney inspection before closing. A standard home inspector typically performs only a basic visual check of the hearth; a certified chimney specialist uses video camera equipment to evaluate the flue’s internal integrity, helping the buyer avoid thousands of dollars in unexpected chimney relining or rebuilding costs after mo
