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.

AfterFamco Chimney Cleaning & Sweep in Baltimore: What to Know First
We provide independent Famco chimney cleaning and sweep service throughout Baltimore, typically scheduling within a few days and completing most jobs in a single visit. A standard Famco sweep and Level 1 inspection runs $175-$265, and we’ll tell you plainly if that’s all you need or if the flue tells a different story. This page is for Baltimore homeowners who’ve found Famco caps, dampers, or venting products in their chimney system and want a technician who recognizes the hardware without guessing. We’re not affiliated with or authorized by Famco - we’re an independent service provider who has worked on enough of their products in Roland Park, Federal Hill, and the rowhouse blocks near Patterson Park to know what holds up and what doesn’t. Call (410) 849-6273 when you’re ready to book.
How Famco Products Fail - and How We Fix Them
- Famco chimney caps in the WC series warp at the lid hinge after five to seven Baltimore winters. The salt-heavy air from the harbor accelerates corrosion at the pivot point, and once the lid binds open, rain enters freely. We remove the cap, assess whether the mesh is still sound, and either rebuild the hinge with stainless hardware or source a compatible replacement that doesn’t sacrifice airflow.
- Famco BD series barometric dampers stick in the partially-open position. Soot accumulation on the weighted blade is the usual cause, especially in Baltimore’s older masonry chimneys with marginal draft. We disassemble the damper, clean the blade and track to factory tolerances, and recalibrate the weight setting so it responds to actual draft pressure rather than guesswork.
- Famco roof vents and exhaust caps collect creosote at the interior baffle in ways that restrict airflow more aggressively than plain metal caps. The baffle design is meant to block backdraft, but in Baltimore’s freeze-thaw cycles, the creosote hardens into a shell. We use rotary whips and hand brushes sized to the vent diameter, then verify flow with a smoke pencil before we leave.
- Famco masonry chimney caps with integrated drip edges separate at the mortar bed. This isn’t a cap failure so much as a cap-to-crown failure, and Baltimore’s brick chimneys show it frequently after hard winters. We document the separation with camera photos, remove the cap, reseat it on fresh crown sealant or rebuild the crown if the concrete has spalled.
- Famco chimney fans in the RV series develop bearing noise after heavy creosote loading. The fan is doing its job, but the motor works harder when the flue isn’t swept regularly. We clean the fan housing and impeller, test amperage draw against spec, and if the bearing is gone, we quote a replacement motor rather than selling you a whole new unit.
Our Famco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, asks what you’re burning, how often, and whether you’ve noticed draft issues or odors. We book a window and send a confirmation.
- 2
Arrival and protection. Our technician arrives in uniform, lays floor protection from the door to the hearth, and inspects the visible Famco components - cap, damper, fan if present - before touching a tool.
- 3
Level 1 or Level 2 inspection. Most Famco sweeps start with Level 1: visual and accessible. If we find damage, creosote buildup beyond normal, or you’re buying the home, we recommend Level 2 with camera inspection. The photos go on the tablet; you see what we see.
- 4
Sweep and component service. We match brush and whip selection to your flue liner and the Famco hardware in place. Dampers come apart for cleaning; caps come off if the crown needs attention. No shortcuts around parts that affect performance.
- 5
Documentation and verdict. You get photos, a plain-English written report, and a verbal walkthrough before we pack up. If something can wait a season, we say so. If it’s unsafe to use, we say that plainly too.
- 6
Cleanup and guarantee. We vacuum, remove protection, and leave the hearth cleaner than we found it. The 90-Day Done Right Promise covers the work in writing - if it’s not right, we make it right, no arguing.

Why Baltimore Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve been answering calls with a live person for over 42 years, and that hasn’t changed because our customers haven’t changed - they still want to speak to someone who knows whether a Famco BD damper can be rebuilt or needs replacing. Russell Haines and our technicians carry DuraFlex, HeatShield, and Gelco materials on the truck alongside Famco-compatible hardware, so we’re not making a second trip because we guessed wrong on parts. The 90-Day Done Right Promise is in writing, not a verbal shrug. Background-checked, uniformed techs. Upfront pricing. Photos you can see, a plain-English verdict. If the flue is right, the fire takes care of itself.
FAQs
No. Famco’s product warranties cover manufacturing defects, not who touches the cap or damper for routine maintenance. We document our work with photos and written reports, so if a genuine defect appears later, you have records that support your claim rather than complicate it. Call (410) 849-6273 if you’d like us to review what’s in your system.
We source OEM Famco parts when they’re available and the job warrants it, but we’ve also found that certain aftermarket stainless hinges and mesh from our regular suppliers outlast the original in Baltimore’s coastal air. We explain the trade-off before we order - cost, availability, and expected lifespan - and you decide.
The inspection tells us. If the flue is sound, the draft measures within range, and the Famco hardware moves freely, a sweep is enough. If the camera shows cracked tile, the damper blade is corroded through, or the fan motor is drawing excessive amps, we show you the evidence and quote repair separately. Nothing is sold on speculation.
Once per burning season for wood-burning systems, or when creosote reaches 1/8 inch thickness. Baltimore’s older homes with marginal draft and the humidity off the Patapsco can accelerate buildup, so we recommend annual inspection even for light use. Gas systems with Famco venting need less frequent sweep but still benefit from cap and fan inspection every two years.
Creosote hardens, restricts draft, and becomes increasingly difficult to remove without aggressive methods or chemical treatment. In the worst case, it ignites. Carbon monoxide risk rises if the flue is partially blocked. The cost of deferred maintenance is always higher than the cost of a scheduled sweep. Call (410) 849-6273 for a free estimate - we’ll tell you where you stand.
