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.

Garrison isn’t like the newer subdivisions east of here. The homes are bigger, older, and built with more fireplaces than most sweep crews expect. Our Chimney Cleaning & Sweep team has been working in northwest Baltimore County for over 42 years, and we’ve learned that a Garrison sweep job isn’t done until every flue in the stack has been inspected, not just the one the homeowner uses most.

Our Chimney Cleaning & Sweep Services in Garrison
Level 1 Inspection
A Level 1 inspection is the baseline for any Garrison home with an actively used fireplace. We examine the readily accessible portions of the chimney exterior, interior, and connecting appliance - checking for creosote buildup, obstructions, and basic structural soundness. In Garrison’s 1960s-80s colonials, we always verify how many flues are present before we start; many homeowners are surprised to learn their chimney has two or three separate clay-tile liners, not one. A Level 1 runs $189-$249 in the Garrison market.
Level 2 Inspection
This is where we earn our keep in Garrison. A Level 2 inspection includes everything in Level 1, plus a camera scan of the full flue interior - the liner walls, the smoke chamber, the damper assembly, and the firebox. We document every finding with photos you can see, and we explain what each image means in plain English. For Garrison’s aging multi-flue masonry chimneys, this is non-negotiable. Clay-tile liners installed in the 1960s, 70s, and 80s are now 40-65 years old. Cracks, spalling, and mortar joint erosion are common, and none of it is visible from the firebox. We swept a 1968 colonial off Berrymans Lane where the homeowners lit maybe six fires a winter and were stunned to see flaky first-degree creosote packed along the smoke chamber. Their oak canopy had grown to within ten feet of the crown, cutting draft enough that even infrequent fires smoldered - we pulled the debris, ran a Level 2 inspection on all three clay-tile flues, and fitted a Gelco cap before the fall seed drop. Level 2 inspections in Garrison typically run $279-$379.
Creosote Removal
Creosote is the reason chimneys catch fire. It builds in three stages: flaky first-degree (sweepable), tar-like second-degree (requires rotary tools), and glazed third-degree (the dangerous stuff, often requiring chemical treatment). In Garrison, we see a distinct pattern: homeowners who “barely use” their fireplaces develop first-degree creosote at the smoke chamber and damper shelf because overgrown tree canopies have choked draft. Reduced airflow means incomplete combustion, and incomplete combustion means creosote - even with minimal use. Our crews use professional-grade rotary systems and, when needed, chemical treatments from Copperfield to break down glazed deposits. Creosote removal in Garrison runs $249-$429 depending on stage and flue count.
Soot Removal & Fireplace Cleaning
Soot is the lighter, powdery byproduct of wood burning, and it accumulates in the firebox, on the damper, and across the smoke shelf. In Garrison’s multi-fireplace homes, we often find the formal living room fireplace pristine while the family room unit - the one that actually gets used - is caked with soot and partially burned debris. We clean the full firebox assembly, the damper mechanism, and the smoke chamber throat. Where access allows, we’ll also inspect and clear the chimney crown of leaf debris and seed pods, which is critical in Garrison’s heavy oak-and-maple canopy. Fireplace cleaning with soot removal runs $189-$289.
Chimney Crown & Cap Service
The crown is the concrete slab that seals the chimney top; the cap keeps rain, animals, and debris out. In Garrison, both take a beating. The freeze-thaw cycle opens hairline cracks in crowns each winter, and the dense tree canopy dumps leaves and helicopter seeds that clog drainage and accelerate spalling. We repair crowns with HeatShield CrownSeal where the damage is moderate, and we install Gelco and Olympia Chimney caps sized to your flue configuration. A proper cap also keeps squirrels and raccoons from nesting - a real problem in Garrison’s wooded lots as temperatures drop. Crown repair runs $349-$649; cap installation with inspection runs $229-$389.

Common Chimney Cleaning & Sweep Problems We See in Garrison Homes
- Multi-flue stacks missed by single-flue sweeps. Garrison’s colonials and Tudors frequently contain two, three, or four clay-tile flues in one masonry stack. Crews from outside the area often inspect the active fireplace and leave, missing cracked or obstructed flues the homeowner forgot existed. We map every flue before we start.
- Draft loss from tree canopy overgrowth. Mature oaks and maples that were saplings when these homes were built now tower within ten feet of chimney crowns. Reduced draft causes incomplete combustion and creosote buildup even in “barely used” fireplaces. We measure draft performance and recommend crown-height or cap solutions when trees are the culprit.
- Freeze-thaw mortar destruction. Baltimore County’s 32°F crossings - dozens each winter - force moisture into hairline cracks, where it expands and erodes mortar joints. By spring, what was a minor gap is a structural concern. Our Level 2 camera inspections catch this before water intrusion damages interior walls.
- Crown debris accelerating spalling. Leaf litter and seed pods accumulate on flat or poorly sloped crowns, hold moisture against the concrete, and speed freeze-thaw deterioration. We clear and document crown condition on every Garrison visit, because ignoring it means rebuilding the crown in five years instead of capping it now.

FAQs - Chimney Cleaning & Sweep in Garrison
No - each fireplace has its own flue, and each flue requires separate inspection and cleaning. We inspect and price per flue, and we’ll walk you through which ones are actively used versus which may have hidden deterioration from disuse. Call (301) 215-3355 and we’ll map your system before quoting.
Because in Garrison, reduced draft from overgrown tree canopies causes incomplete combustion even with infrequent use. We’ve found first-degree creosote in fireplaces lit six times a winter. The NFPA recommends annual inspection for all masonry chimneys regardless of use, and in Garrison’s conditions, we agree. An annual sweep catches draft problems and liner cracks before they become hazardous - call (301) 215-3355 to schedule.
It destroys mortar joints and cracks clay-tile liners. Each time temperatures cross 32°F, moisture in hairline cracks expands and contracts, widening the gap. Garrison’s all-masonry chimneys experience this dozens of times each winter. Our Level 2 camera inspections document the damage in photos you can see, and we explain what needs immediate attention versus what can be monitored. Call for a free inspection estimate.
Yes - directly. When mature oaks and maples shade the chimney crown, they reduce the temperature differential that drives draft. Cooler, slower exhaust means more creosote deposition at the smoke chamber and damper. We’ve measured draft reductions of 30% or more in heavily shaded Garrison chimneys. Trimming branches helps; a properly engineered cap helps more. We assess both during your inspection.
We do - and we install them too. We work with DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. If your existing cap, liner, or damper is from one of these manufacturers, we can service, repair, or replace with matching professional-grade components. No mixing grades, no improvised fits. Call (301) 215-3355 and we’ll identify what’s on your chimney and what it needs.
