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.

AfterGelco Chimney Cleaning in Lansdowne, MD | Hearthstone Chimney Co.
Gelco chimney cleaning and repair in Lansdowne typically runs $180-$340 for a full sweep with Level 2 camera inspection, and most jobs are completed in a single visit. What makes our Gelco work different here is Lansdowne’s concentration of post-WWII homes with original masonry chimneys converted from coal to gas, often with unlined or shared flues that require specialized diagnosis. We are an independent chimney service company, not manufacturer-affiliated, and we’ve worked on Gelco systems across Baltimore County for over 42 years. Call (410) 849-6273 to schedule your free estimate.
Why Lansdowne Residents Choose Us for Gelco Service
We know Gelco masonry firebox assemblies, multi-flue caps, and dampers the way a mechanic knows an engine he’s rebuilt a hundred times. Russell Haines, our owner, learned the trade at Los Angeles Trade-Technical College, but it’s Baltimore’s older rowhouses and brick chimneys that have kept him and our crew busy for years. He’s spent well over a decade doing this work full-time, and he’s become the kind of sweep people call back every season without thinking twice about it.
In Lansdowne specifically, that reputation matters. This is a post-WWII working-class suburb where the housing stock was built for steel and industrial workers, and the chimneys reflect that history. We carry Gelco-compatible caps, dampers, and crown materials in our local inventory, which means faster turnaround for Lansdowne homeowners. Our technicians are background-checked and uniformed, and we back every job with the 90-Day Done Right Promise in writing, no arguing. A live person answers our phone 24 hours a day, 7 days a week. Gelco sales & service is a core part of what we do, and Lansdowne service area is territory we know well.
Common Gelco Chimney Cleaning Problems We Solve in Lansdowne
- Gelco firebox mortar failure from fuel conversion: Lansdowne’s 1940s-1960s homes were built with coal-burning Gelco fireboxes that were later converted to oil or gas, often without proper relining. The original mortar joints degrade under decades of temperature cycling and incompatible flue gases, creating gaps where carbon monoxide can seep into living spaces.
- Gelco multi-flue cap corrosion in the Patapsco valley: The humid freeze-thaw cycle along the Patapsco River valley destroys Gelco multi-flue caps faster than in drier inland areas. We’ve removed caps that had corroded through entirely, allowing rainwater to pour directly into unlined flues and accelerate brick spalling from the inside out.
- Gelco damper seizure from creosote and rust: When a former coal flue now vents a low-temperature gas furnace, condensation mixes with residual creosote and rust to bind the damper mechanism. Lansdowne’s long heating season gives this problem months to develop each year.
- Gelco crown cracking from valley moisture: The original mortar washes out of Lansdowne chimney crowns over 60-80 years, and winter moisture freezes inside the brick. Gelco cast-in-place crowns are particularly vulnerable once the underlying structure begins to fail.
- Shared flue hazards in converted homes: Many Lansdowne properties have a bricked-up first-floor fireplace and a basement gas furnace using the same original Gelco flue. This configuration, common in this steelworker suburb but rare in newer Baltimore County communities, creates carbon monoxide risks that a basic sweep will not catch.
Gelco Service in Lansdowne: What Local Conditions Mean for Your Equipment
Many Lansdowne homes have a bricked-up first-floor fireplace and a basement gas furnace sharing the same original Gelco flue, a configuration that is common in this post-WWII steelworker suburb but rare in newer parts of Baltimore County. This dual-era use of one undersized, often unlined flue is the carbon monoxide risk we check for first on every Gelco chimney in Lansdowne. The clay tile liners in these chimneys were sized for coal combustion temperatures far higher than today’s gas appliances produce, which means inadequate draft, condensation damage, and accelerated deterioration of the Gelco firebox and crown assembly. We recently serviced a 1950s Cape Cod on Hammonds Ferry Road where the homeowner had exactly this setup and needed Chimney Cleaning & Sweep - Lansdowne to address years of buildup. Our Level 2 inspection revealed a cracked clay tile and a missing Gelco multi-flue cap that had been allowing water into the chimney for years. We repointed the mortar joints, installed a new stainless steel Gelco cap, and waterproofed the brick, bringing the flue back to safe service for the furnace. If the flue is right, the fire takes care of itself.
Gelco Models & Products We Service in Lansdowne
We work on the full range of Gelco chimney systems found in Lansdowne’s housing stock: Gelco masonry firebox assemblies, Gelco multi-flue chimney caps, Gelco stainless steel chimney caps, and Gelco cast-in-place chimney crowns. Our approach is straightforward. We stock quality aftermarket Gelco-compatible caps, dampers, and crown materials that match original dimensions, and we source OEM Gelco parts when a specific component is still available. If a Gelco chimney has cracked clay tiles or a failing crown, we recommend our Chimney Repair in Lansdowne with targeted repair over full replacement whenever the structure is sound. We will not patch over a flue that is unsafe for modern appliance venting. That honest assessment is why Lansdowne homeowners call us back.

FAQs - Gelco Chimney Cleaning in Lansdowne
A Level 2 inspection uses a camera to examine the interior flue, which is essential in Lansdowne because so many homes have converted coal chimneys with hidden clay tile damage or shared flue configurations a basic sweep cannot assess. The photos become your documentation. Call (410) 849-6273 to schedule.
A Gelco multi-flue or stainless steel cap that is merely loose can often be re-secured, but once corrosion has compromised the metal or the mesh, replacement with a Gelco-compatible cap is the sound repair. We stock caps sized for Lansdowne’s original brick chimneys and install same-day in most cases.
Given Lansdowne’s humid Patapsco valley climate and freeze-thaw cycling, we recommend professional chimney waterproofing every 5-7 years for Gelco brick that is otherwise sound. More frequent treatment may be needed if the crown is already cracked or the mortar joints are eroding.
Yes. We clean, lubricate, and adjust Gelco dampers, and we replace the mechanism when corrosion or warping has made repair impractical. A stuck-open damper in winter wastes significant heat; a stuck-closed damper is a safety hazard.
Missing or cracked clay tiles allow flue gases and carbon monoxide to escape through the chimney walls into your home. In Lansdowne’s converted coal chimneys, this risk is elevated because the original flue was not designed for gas appliance temperatures and draft characteristics. Do not operate a furnace through a damaged flue. Call (410) 849-6273 for an emergency inspection and free estimate.
