Level 1 vs. Level 2 Chimney Inspections in Somerville: Which One Do You Need?

By Felix Chimney Company Team · Updated August 11, 2026

In Somerville, most routine chimney checks are Level 1 inspections, which cover the parts you can see from the fireplace up to the roof. A Level 2 inspection is more thorough and required after major events like a chimney fire or when you sell your home. Felix Chimney Company offers both to keep your chimney safe and code-compliant.

Myth: All chimney inspections are the same — just a quick look inside

A chimney inspection is not a one-size-fits-all service. The Chimney Safety Institute of America (CSIA) defines three levels of inspections, with Level 1 being the most common for routine maintenance and Level 2 required after specific events or changes in use. In Somerville, where many homes are older and chimneys are tucked between triple-deckers or under dormers, a quick visual from the firebox isn’t enough to spot hidden damage. A Level 1 inspection includes checking the flue from the fireplace to the chimney cap, looking for obstructions, creosote buildup, and basic structural issues. But it doesn’t require special tools or entering concealed spaces. If you’ve recently had a chimney fire on Highland Avenue or replaced your furnace on Beacon Street, you’ll likely need a Level 2 inspection to check behind walls and in attics. Felix Chimney Company tailors each inspection to your home’s history and layout, so you’re never paying for more than you need. Learn more about our full list of services.

What most Somerville homeowners get wrong about Level 2 inspections

Many Somerville homeowners assume a Level 2 inspection is only needed when buying or selling a home. While it’s true that a Level 2 inspection is often required during real estate transactions, it’s also triggered by events like a chimney fire, a change in fuel type (e.g., switching from wood to gas), or after major renovations that could affect the chimney’s structure. The National Fire Protection Association (NFPA) recommends a Level 2 inspection in these cases to ensure hidden damage hasn’t compromised safety. Felix Chimney Company sees this often in Somerville’s older stock of homes, where chimneys may have shifted over time or been modified without permits. A Level 2 inspection includes everything in a Level 1, plus a video scan of the flue, inspection of attics, basements, and crawl spaces, and a review of accessible portions of the chimney exterior. It’s not just about ticking a box for the bank — it’s about preventing a silent hazard in your home. See request a free estimate / contact us.

A chimney inspection is only as good as the inspector’s access — and your home’s quirks

A chimney inspection is a systematic check of your chimney system to identify hazards, damage, or code violations. In Somerville, where homes range from vintage triple-deckers on College Avenue to newer condos on McGrath Highway, access can be tricky. A Level 1 inspection covers the readily accessible portions of the chimney, fireplace, and connected flue. If your chimney runs through a shared wall or is partially enclosed in an addition, the inspector may need to use a borescope to peer around bends. Felix Chimney Company uses high-resolution cameras and flexible scopes to navigate Somerville’s tight spaces safely. For a Level 2 inspection, the inspector will also examine concealed areas like attics, basements, and behind walls where chimneys often hide damage. If your home has a chimney chase or a prefabricated chimney system, a Level 2 inspection ensures the chase isn’t hiding rust, water damage, or improper clearances. Always confirm your inspector is CSIA-certified and carries liability insurance — Felix’s team meets both standards. Explore about our team and credentials.

Somerville’s climate and housing stock make chimney damage sneakier than you think

Somerville’s mix of old and new housing, combined with humid summers and freezing winters, accelerates chimney wear in ways many homeowners overlook. A chimney cap is your first line of defense, but even capped chimneys can suffer from hidden water intrusion, especially in homes near the Mystic River or under the flight path of planes landing at Logan. A Level 1 inspection might catch obvious issues like cracked mortar or a missing flue tile, but it won’t spot water damage behind the chimney crown or in the attic where insulation hides moisture. Felix Chimney Company often finds this in homes on Highland Avenue or near Union Square, where decades of freeze-thaw cycles have weakened chimneys. A Level 2 inspection uses a camera to peer into these hidden zones, spotting rust in prefab chimneys or deteriorating masonry in older brick stacks. Don’t wait for a leaky ceiling to tell you there’s a problem — schedule the right inspection now.

Costs and timing: How much does a Level 1 vs. Level 2 inspection really cost in Somerville?

In Somerville, a Level 1 chimney inspection typically costs between $120 and $180, while a Level 2 inspection ranges from $200 to $350. The price difference reflects the extra time, equipment, and access required for a Level 2. Felix Chimney Company offers free estimates and can bundle inspections with sweeps or repairs to save you money. Timing matters too: scheduling during off-peak seasons (late spring or early fall) can reduce wait times, especially in competitive markets like Somerville. If you’re buying a home on Prospect Street or preparing to list your place on Broadway, a Level 2 inspection is a smart investment to avoid last-minute surprises. Felix’s team can often complete both inspections in one visit, so you’re not juggling multiple appointments. Always ask for a written report with photos — it’s invaluable for insurance claims or real estate disclosures.

When to insist on a Level 2 inspection — even if no one’s telling you to

You should always request a Level 2 inspection if your home has experienced a chimney fire, a major earthquake (yes, they happen in Massachusetts), or if you’ve changed the fuel type from wood to gas. Felix Chimney Company also recommends a Level 2 inspection if your chimney hasn’t been inspected in over a year or if you’re unsure about its history — especially in Somerville’s older neighborhoods like Winter Hill or the Heights. Another trigger? If your chimney is partially or fully enclosed in a chase, or if you’ve had recent renovations that could have altered the chimney’s structure. The EPA’s Burn Wise program warns that even minor damage can lead to carbon monoxide leaks or chimney fires, so don’t skip this step. Felix’s Level 2 inspections include a video scan, so you’ll see exactly what’s happening inside your flue. It’s the only way to be certain your chimney is safe.
