Gideon Chimney Sweep Pros
Historic Baltimore residential chimneys rely on soft lime mortar formulated over a century ago. Standard modern Portland cements create rigid stress points that spall nineteenth-century bricks during winter freeze-thaw cycles. We analyze mortar chemistry and flue tile alignment before initiating any structural repointing.
Original draft configurations were engineered for low-efficiency coal and wood combustion. Converting or maintaining these draft corridors requires precise internal smoke chamber measurements, correct damper seating, and custom stainless spark arrestor caps designed to maintain proper draw without compromising architectural rooflines.


Containment and diagnostics
Before sweeping begins, we lay triple-layer neoprene floor runners and seal the fireplace opening with magnetic vinyl containment barriers. Continuous HEPA filtration systems maintain negative air pressure throughout the sweep, capturing microscopic soot particles before they enter your living room air.
Every repair recommendation requires unedited video proof. Homeowners must clearly see internal flue conditions on screen before committing to structural masonry work.
