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 Lansdowne chimneys for decades. The 1940s-1960s Capes and bungalows along Hollins Ferry Road, the brick homes near Lansdowne High School, the smaller two-story houses off Hammonds Ferry - our technicians know what they’ll find before they step inside. Original masonry flues. Clay tile liners that have seen sixty to eighty winters. Coal-era chimneys pressed into service for oil, then gas, often without the relining that conversion should have demanded. That’s not a sales pitch. It’s the housing stock.
Our Chimney Cleaning & Sweep team doesn’t guess. We run a camera. We show you what we see. Then we tell you what it means in plain English.

Our Chimney Cleaning & Sweep Services in Lansdowne
Level 1 Inspection
A Level 1 inspection is a visual examination of the readily accessible portions of your chimney and fireplace. For Lansdowne homeowners with newer gas inserts or recently serviced systems, this may be sufficient. But given the age of most Lansdowne housing stock, we often recommend starting with Level 2. A Level 1 runs $150-$195 in the Lansdowne market.

Level 2 Inspection
This is where we do our real work in Lansdowne. A Level 2 inspection includes everything in Level 1 plus camera examination of the interior flue, inspection of attics and crawl spaces where accessible, and documentation of liner condition, mortar joints, and crown integrity. For the 1950s brick Capes near Lansdowne Elementary and the converted rowhouse-style homes off Washington Boulevard, this is essential. The camera finds what eyes cannot: cracked clay tile, missing liner sections, spalling from Patapsco valley moisture, and the dangerous conversion gaps where a gas furnace vents into a coal-era flue. Level 2 inspection in Lansdowne costs $275-$375.
We were called to a 1952 brick Cape on 4th Avenue in Lansdowne where the homeowner had a bricked-up first-floor fireplace and a gas furnace venting into the same unlined flue. Our tech ran a camera and found missing clay tile and heavy spalling on the chimney crown; we swept the accessible flue, removed soot and first-degree creosote, and installed a HeatShield liner sized for the furnace. The draft improved immediately, and we showed the homeowner the before-and-after camera footage before recommending any work.

Creosote Removal
Creosote builds in any chimney that vents wood smoke, but in Lansdowne we also find it in chimneys serving oil systems and in the occasional homeowner who burns wood in a fireplace that hasn’t been properly inspected. First-degree creosote - flaky, sooty, easily brushed - is common and straightforward to remove. Third-degree creosote, glazed and hardened, requires rotary removal and sometimes chemical treatment. In Lansdowne’s older flues with irregular surfaces from deteriorating clay tile, third-degree creosote adheres more tenaciously. Removal runs $195-$325 depending on severity and accessibility.

Soot Removal
Soot accumulation is the quieter problem. Gas furnaces produce fine, acidic soot that coats unlined or damaged flues, gradually narrowing the passage and corroding masonry. In Lansdowne homes where a basement gas appliance vents through a coal-era chimney, we find this routinely. The soot itself is less flammable than creosote, but it signals poor draft and potential liner failure. Standard soot removal as part of an annual sweep runs $175-$225. If we’re addressing heavy accumulation in a neglected system, $250-$340.

Annual Sweep
NFPA 211 recommends annual inspection for all chimneys, vents, and flues - regardless of fuel type. In Lansdowne, with heating seasons that stretch from October through April and humidity that never fully quits, that annual cycle matters. Our seasonal sweep includes visual inspection, flue brushing, smoke chamber and firebox cleaning where accessible, and a condition report. $175-$225.

Fireplace Cleaning
For Lansdowne homeowners who still use original or restored fireplaces, we clean fireboxes, smoke chambers, and dampers, checking for proper operation and clearances to combustibles. Given the age of these installations, we often find damaged mortar, missing bricks, or improper clearances that were grandfathered in decades ago. Fireplace cleaning runs $195-$275.

Common Chimney Cleaning & Sweep Problems We See in Lansdowne Homes
- Unlined coal-era flues venting modern gas furnaces. The clay tile liner was sized for coal combustion temperatures and may be cracked, missing, or never installed. A low-temperature gas appliance in that flue produces acidic condensation that deteriorates mortar and allows carbon monoxide to seep into wall cavities. Our camera finds it. We show you.
- Patapsco valley freeze-thaw damage. Lansdowne sits in the river valley corridor where winter humidity wicks into aging brick, freezes, expands, and spalls the face off mortar joints and chimney crowns. We see this accelerated deterioration on homes near the river and in low-lying pockets off Hollins Ferry Road.
- Bricked-up fireplaces sharing flues with basement appliances. A first-floor fireplace sealed decades ago, the same flue now venting a gas furnace below. Two different combustion eras, one chimney, often no liner sized for either current use. No visual sweep catches this. Only a camera inspection reveals the hidden cross-contamination path.
- Deteriorated chimney crowns letting water into the flue. Concrete crowns crack, steel reinforcing rusts and expands, and water runs straight down into the smoke chamber. In Lansdowne’s older brick construction, this accelerates everything - liner damage, mortar washout, interior staining. We document crown condition on every Level 2 inspection.

FAQs - Chimney Cleaning & Sweep in Lansdowne
Yes. That exact configuration is the most common hidden hazard we find in Lansdowne. A bricked-up first-floor fireplace sharing a flue with a basement gas furnace is two eras of combustion in one chimney, often with no liner sized for modern low-temperature gas. A Level 2 camera inspection is the only way to see missing clay tile, cracked mortar, or dangerous cross-contamination paths that a visual sweep cannot detect. Call (410) 849-6273 to schedule - estimates are free.
Lansdowne’s location in the Patapsco River valley means higher winter humidity and more pronounced freeze-thaw cycling than drier inland areas. Moisture wicks into aging brick and mortar, freezes, expands, and spalls the surface - accelerating crown deterioration, mortar joint failure, and flue liner damage. We inspect for this specifically on every Lansdowne Level 2. Call (410) 849-6273 for an exact quote.
First-degree creosote is flaky, sooty, and brushes off easily - common in well-maintained systems and straightforward to remove for $195-$250. Third-degree creosote is glazed, hardened, and tar-like, requiring rotary mechanical removal and sometimes chemical treatment; in Lansdowne’s older flues with irregular clay tile surfaces, it adheres more stubbornly and runs $275-$325. We classify what we find with the camera and price accordingly before starting work. Call (410) 849-6273 to book.
No. We never recommend liner work, crown repair, or any significant repair without showing you the camera footage and explaining what it means. The photos are yours. The verdict is plain English. If the work can safely wait, we say so. If it’s urgent, we show you why. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. Call (410) 849-6273 - estimates are free.
Gas and oil appliances produce acidic condensation, fine soot, and - in malfunctioning systems - carbon monoxide. The chimney venting them deteriorates from the inside, unseen. NFPA 211 applies to all fuel types because liner failure, blockages, and appliance misalignment happen regardless of what you burn. In Lansdowne’s converted coal-era chimneys, this annual check is especially critical. Call (410) 849-6273 to schedule your inspection.
