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.

Why Alcott Chimney Sweep Is Lawrence’s Preferred Chimney Inspection Company
Lawrence is not like the single-family suburbs across the Methuen or Andover line. The housing stock here is mostly late-1800s to early-1900s mill-worker tenements and triple-deckers, often with original masonry chimneys that are now 100 to 130 years old. A chimney inspection in Lawrence routinely means one brick stack serving two or three separately rented apartments, each with its own flue, its own owner or landlord, and its own history of repairs, or lack of them. Our Chimney Inspection team knows these buildings because we work on them every week. We have mapped flues in triple-deckers where the second-floor furnace was venting into a smoke chamber still tied to the first-floor fireplace. That kind of finding doesn’t come from a generic checklist. It comes from walking the roof, running the camera, and tracing every flue before we tell you anything is safe.
Ruben Castellano runs Alcott Chimney Sweep with a plain-spoken rule: show the homeowner the proof. Every technician who comes to your door is background-checked and identity-verified under the Threshold Standard, and you will know that technician’s name and see their photo before we arrive. When we finish, you get a written report and photos from the camera, not just a verbal “looks fine.” Lawrence homeowners have told us they value that because so much of this housing stock has changed hands, changed tenants, and changed heating systems without any paper trail.
Chimney Inspection Services in Lawrence
Chimney Inspection Services in Lawrence cover three levels, and most calls we field fall into two categories: homeowners who just want to know if they can safely burn, and landlords or buyers who need documentation for a transfer or a rental unit. A standard Level 1 inspection in Lawrence runs $189 – $249 and is the right call when nothing has changed since the last sweep and you burn regularly. A Level 2 inspection, which runs $329 – $429 and includes a camera scan of every flue, is what you want if you lit a fireplace during the 2018 Columbia Gas outage and never had it checked, or if a new furnace was installed during the rebuild. A Level 3 inspection is reserved for serious concern: visible damage, a possible fire event, or a masonry problem that requires opening a wall. That starts at $750, and we will show you exactly why it is necessary before any work is scheduled.
Level 1 and Level 2 Inspections
A Level 1 is a visual inspection of the accessible parts: firebox, damper, flue opening, exterior crown. A Level 2 adds the camera. In a city like Lawrence, where so many flues are shared, unlined, or abandoned, the camera is not an upgrade. It is the difference between guessing and knowing.
Real Estate and Transfer Inspections
For closings in Lawrence, a Level 2 inspection is the standard documentation buyers ask for. For multi-unit sales, we document each flue separately, with photos, so the report reflects reality, not a best guess.

Chimney Flue Inspection in Lawrence
Chimney Flue Inspection in Lawrence is where most of the serious findings happen. The flue is the passage the exhaust actually travels through, and in this city the flue is often the oldest, least-documented part of the house. A flue inspection in Lawrence runs $189 – $329 depending on whether the camera is included, and we recommend the camera on every shared-stack or post-2018 flue. The Columbia Gas rebuild swapped thousands of heating appliances across the city, and a meaningful number of those new furnaces were vented into flues that had not been checked, lined, or even identified. If your heating system changed in late 2018 or after, you may not know which flue your appliance is using. A camera inspection tells you, in pictures, on site.
Matching Flue to Appliance
In a triple-decker, the flue that serves your furnace may not be the one you assume it is. We document each flue’s route and condition independently, so you know what your appliance is actually venting into.
Shared-Stack Cross-Contamination
When three units share one brick stack and the flues were never mapped, a neighbor’s appliance can push exhaust, carbon monoxide, or creosote odor into your unit. We trace each flue and identify where the paths cross, and we show all affected parties the photos.
Trusted Brands We Service in Lawrence
When a Lawrence inspection turns up a liner problem, we work with the trade brands chimney professionals specify: DuraFlex, HeatShield, Olympia Chimney, and Copperfield. These are not box-store substitutes. We stock common components for these systems and can typically get a repair underway quickly for Lawrence customers, which matters when you are trying to get a rental unit back into safe operation. If your flue needs resurfacing, HeatShield is the product we use most often in older Lawrence chimneys because it handles irregular, deteriorated flue surfaces well.
Common Chimney Inspection Problems We See in Lawrence Homes
- Mismatched liners from the 2018 rebuild. New furnaces were installed under emergency conditions, and many were vented into flues that had never been checked, lined, or even positively identified. A Level 2 camera inspection is the only way to verify the match.
- Freeze-thaw crown and mortar damage. Lawrence sits in the Merrimack River valley, where cold, moist air and heavy snow on low-pitch triple-decker roofs accelerate spalling in aged brick mortar. Cracked crowns and deteriorated joints are routine findings here, and they let water into the flue.
- Shared-stack cross-contamination. One chimney stack serving three separately rented units means three landlords and three flues, often never mapped. A neighbor’s exhaust or CO can push into an adjacent unit, and nobody knows until we trace it.
- Third-degree creosote from emergency heating. Homes that lit dormant fireplaces as emergency heat during the 2018 Columbia Gas outage often built up heavy, glazed creosote. That hardened tar-like residue is a fire hazard, and it requires professional removal and a full inspection before the next burn.

FAQs About Chimney Inspection in Lawrence
Yes, and it must. A Level 2 inspection on a shared Lawrence stack should document every flue independently, because each flue serves a different unit and a different owner. We trace each flue with the camera, map where it terminates, and report each one separately, so the second-floor landlord knows about the second-floor flue, not a vague summary of “the chimney.” Call (336) 863-3889 and we will walk you through what the report includes before we book the job.
You know by running a camera through the flue and comparing the liner’s size, material, and condition against the BTU and venting requirements of the appliance now attached to it. We found furnace venting into unlined, previously abandoned flues on multiple Lawrence jobs after the rebuild. The physical match matters, and the only credible way to confirm it is a Level 2 camera inspection with photos you can see.
Still at least once. Even a dormant flue in an older Lawrence building takes water, freeze-thaw damage, and possible cross-contamination from an adjacent unit that is still burning. If you stopped burning after the 2018 outage but have not had anyone inspect since, book a Level 2 once now, document the condition, and then reassess annually based on what the report shows.
Access and sign-off depend on the scope. For a full inspection that requires roof access, ladder placement, and inspection of shared masonry, we typically need approval from the owner or property manager responsible for the areas we access. For flue-specific camera work on one unit’s flue, the permission of that unit’s owner is often enough. We will tell you exactly who needs to sign what before we book, and we coordinate across multiple landlords so no one is left guessing.
It looks like black, glossy, tar-like glaze baked onto the flue walls, often with a hard, shiny surface. Third-degree creosote is concentrated fuel. It is the most dangerous form, and it burns hot and fast once ignited. If your fireplace saw emergency use during late 2018 and has not been inspected since, do not light it again. Call (336) 863-3889 for an inspection first. The estimate is free, and you will get a written report with photos before anyone asks for a dollar beyond the inspection price.
