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.
Chimney Company in Garrison, MD
Garrison, Maryland homes rarely have just one fireplace. The custom colonials and Tudors built through the 1960s – 1980s along Garrison Forest Road and Old Court Road often carry two or three flues, most still lined with the original clay tile that’s now cracking and spalling after decades of Baltimore County freeze-thaw cycles. That’s why a chimney call in Garrison usually means inspecting multiple flues, not one. Alcott Chimney Sweep handles sweeping, inspection, and gas fireplace repair here, with written pricing before any work starts. Call (336) 863-3889 to schedule.
Why Garrison Homes Are Different
The housing stock here isn’t like the tighter lots and newer construction you see closer to the Beltway. Garrison sits on large, heavily wooded parcels where mature oaks and hardwoods shade the rooflines year-round. Those trees drop twigs, leaves, and seed pods onto chimney crowns, and the shade keeps masonry damp far longer than it would be in open sun. Damp masonry in a freeze-thaw climate is exactly what cracks clay flue tiles and mortar crowns.
Most of these chimneys were built with clay tile liners, which the trade expects to last about 50 years. Homes constructed between 1960 and 1985 are now well past that mark. We routinely find spalled tile faces, cracked mortar joints, and crowns that have separated from the flue. Add in the squirrels and chimney swifts that thrive in Garrison’s tree canopy, and a chimney that hasn’t been opened in a season or two is often blocked with nesting material the homeowner never saw from the ground.
There’s a pattern we see often in Garrison specifically: the secondary fireplace in the finished basement or large family room was a selling feature in the 1970s. By the time the current owner calls us, that fireplace hasn’t been lit in years. The damper is frozen shut, the flue is packed with debris, and what looked like a working second fireplace is decorative in practice. That’s fine to know, and we’ll tell you plainly after an inspection what you have and what it needs.
Our Main Garrison Services
Garrison homeowners call us most often for two things: a chimney sweep before burning season, and an inspection when they’re not sure what shape their older flues are in. Below are the three services we offer in Garrison, each with its own dedicated page.
Chimney Sweep in Garrison
A sweep in Garrison typically means working on chimneys that haven’t been opened in years, often with two or more flues to clear. We remove creosote – the tar-like buildup that causes chimney fires – along with leaves, twigs, and the squirrel and bird nests that are common in this heavily treed area. Because we know the local housing stock, we’re prepared for clay tile liners that may already be compromised, and we’ll tell you if we see tile debris in the firebox while sweeping. Chimney Sweep in Garrison covers pricing and what the full visit includes.

Chimney Inspection in Garrison
Inspections in Garrison are about answering one question honestly: is this flue safe to use this year? Given the 40-to-60-year-old clay liners throughout this area, we pay close attention to spalling, cracked mortar joints, and crowns that are letting water in. A camera inspection shows you exactly what we see inside the flue, so you’re not making a liner decision based on someone else’s word alone. Chimney Inspection in Garrison explains the levels of inspection and when each makes sense.

Gas Fireplace Repair in Garrison
Many Garrison homes that were built with wood-burning fireplaces now have gas inserts or gas logs in at least one of them. We service gas fireplaces and inserts, including ignition problems, pilot lights that won’t stay lit, and worn thermocouples. Older inserts in this area often have control systems that haven’t been touched since installation, and we’ll give you a straight answer on repair versus replacement. Gas Fireplace Repair in Garrison details common repairs and what a service call includes.
