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.

We’ve been working on Randallstown chimneys for over 42 years, and we know the local housing stock inside out. The brick colonials and split-levels off Liberty Road, the ranchers near Old Court, the tidy developments around Winands - these aren’t abstract neighborhoods to us. They’re where we find the same patterns again and again: original clay flue tiles from the 1960s and 1970s, oil-to-gas conversions that never got proper liners, and freeze-thaw damage that accelerates every winter. Our Chimney Cleaning & Sweep team doesn’t guess at what’s wrong. We run a camera, show you the footage, and tell you straight what needs doing now, what can wait, and what doesn’t need doing at all.

Our Chimney Cleaning & Sweep Services in Randallstown
Level 1 Inspection
A Level 1 inspection is the baseline for any Randallstown chimney that’s been in regular use without changes to the appliance or venting. We examine the readily accessible portions of the chimney exterior, interior, and flue, checking for obstructions, creosote buildup, and basic structural soundness. For a well-maintained fireplace in a Randallstown rancher with no known issues, this is often sufficient. But for the 1960s-70s stock we see across Randallstown, we frequently recommend stepping up to Level 2.

Level 2 Inspection
This is where we earn our keep in Randallstown. A Level 2 inspection adds a full camera run of the flue interior, accessible attic and crawl-space examination, and documentation of every joint, crack, and creosote deposit. On a split-level off the Liberty Road corridor, our tech swept a fireplace flue and found the original clay tiles factory-sized for an oil burner that had been swapped to gas decades earlier with no stainless insert, so the oversize flue was running cold and wet. The exterior brick was already showing efflorescence, and a Level 2 camera run showed separated tile joints; we documented the footage on-screen with the homeowner, then set a correctly sized HeatShield liner rather than selling a tear-out. That’s the difference between a sweep who sells fear and a sweep who shows proof. Every Level 2 ends with photos you can see and a plain-English verdict.

Creosote Removal
Randallstown’s older chimneys - especially those with unlined or improperly lined flues - accumulate creosote faster than modern systems. Cooler gas exhaust in an oversized clay tile condenses tar and carbon deposits that harden into third-degree glaze, the kind that won’t brush off with a standard sweep. Our techs use professional-grade mechanical whips and chemical treatments to break down glazed creosote safely. We don’t scrape blindly. We camera the flue first, identify the creosote stage, and choose the removal method that actually works for your specific flue condition.

Soot Removal
Soot buildup is less hazardous than glazed creosote but still restricts draft and stains hearth surrounds. In Randallstown’s oil-to-gas conversion chimneys, we often find a powdery black soot mixed with sulfur residue from decades of oil exhaust - a combination that standard brushes can redistribute rather than remove. Our rotary cleaning system captures debris at the source, and we protect your flooring and furniture with drop cloths and HEPA vacuums. The job isn’t done until the flue is clean and the room is cleaner than we found it.

Annual Sweep & Fireplace Cleaning
The National Fire Protection Association recommends annual inspection and sweeping for all wood-burning systems. In Randallstown, we’d add: given the age of your chimney and the freeze-thaw cycling in Baltimore County, annual is the minimum. Our seasonal sweep includes full debris removal, firebox and damper cleaning, smoke chamber inspection, and a written condition report. We also check for animal nesting - squirrels and raccoons love the tall masonry stacks on Randallstown colonials, and a blocked flue is a carbon monoxide hazard you won’t detect until it’s serious.

Common Chimney Cleaning & Sweep Problems We See in Randallstown Homes
- Oil-to-gas conversions with no liner insert. Across Randallstown’s 1960s-70s stock, we repeatedly find chimneys that were factory-sized for high-temperature oil-burner flue gases and later converted to gas venting without a code-required stainless liner insert. The original oversized clay tile stays wet from cooler gas exhaust, accelerating deterioration in a failure mode that shows up as white efflorescence staining on exterior brick before the homeowner suspects any chimney problem.
- Freeze-thaw spalling of original flue tiles. Baltimore County’s climate delivers repeated freeze-thaw cycles each winter, with temperatures crossing 32°F frequently through December-March. This accelerates mortar joint erosion and causes clay flue tiles in Randallstown’s aging chimneys to spall and delaminate faster than in milder Mid-Atlantic areas, making annual inspections especially critical here.
- Backdrafting and condensation in oversized flues. The original clay tiles in Randallstown’s split-levels and colonials were designed for oil furnace exhaust temperatures near 500°F. Modern gas appliances exhaust at 300-350°F. That temperature drop in an oversized flue causes condensation, which mixes with sulfur residue to form acidic sludge that corrodes mortar joints from the inside out.
- Sales-first sweeps condemning flues on sight alone. Without a Level 2 camera inspection the homeowner can watch, a 50-70 year old Randallstown flue gets condemned whether or not the tile joints are actually failing. We’ve saved Randallstown homeowners thousands by documenting intact flues that other sweeps declared “unsafe” - and we’ve caught genuinely dangerous conditions that a quick visual sweep would have missed entirely.
