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.

Our Chimney Liner & Rebuild Services in Catonsville
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Catonsville chimneys with cracked or missing clay tile. We size every DuraFlex liner to the appliance - furnace, fireplace, or water heater - not to the oversized flue left behind by a coal-to-oil-to-gas conversion. In Catonsville’s multi-flue stacks, correct sizing matters more than in newer construction. A liner too large kills draft and accelerates creosote. A liner too small risks spillage. We measure twice, install once, and back it with the 90-Day Done Right Promise.
Flexible Liner Systems
Some Catonsville chimneys have offsets or bends that rigid pipe can’t navigate - especially in the older homes off Frederick Road with shifted mortar joints from decades of Piedmont freeze-thaw cycling. We use flexible liner systems when the flue path demands it, always insulating for the appliance and never dropping a one-size-fits-all solution into an oversized coal-era flue. The flexible systems we install are rated for the specific fuel and venting temperature of your appliance.
Liner Replacement
Full liner replacement is common in Catonsville homes where the original clay tile has spalled, cracked, or simply never existed. Many of the 1910s-1950s brick and stone homes in the Paradise and Westchester neighborhoods were built with unlined flues or with clay tile that has deteriorated past repair. We remove the failed material, inspect the surrounding masonry for soundness, and install a new liner system sized to your current appliance. If the chimney stack itself is compromised, we’ll tell you plainly - and show you the camera evidence - before recommending a partial rebuild.
Partial Rebuild
A partial rebuild addresses the section of chimney that has failed without tearing down what still stands. In Catonsville, we see this most often on the upper courses above the roofline, where Piedmont wind exposure and freeze-thaw cycling spall brick and erode mortar joints. We also rebuild crowns and seal abandoned flue openings that let moisture and neighbor-appliance exhaust migrate into living spaces. A partial rebuild preserves the original character of your home while fixing the problem. Done right - and we stand behind it.

Trusted Brands We Service in Catonsville
We don’t use builder-grade substitutes. Our Catonsville crews work with professional-grade materials from DuraFlex, HeatShield, and Gelco - brands specified by chimney professionals because they hold up to real conditions, not showroom displays. We stock common liner diameters and repair materials locally, so most Catonsville jobs don’t wait on shipping. When we recommend a product, it’s because we’ve installed it, seen it perform through Maryland winters, and trust it to last.
Common Chimney Liner & Rebuild Problems We See in Catonsville Homes
- Original clay-tile liner spalled from freeze-thaw cycling. Catonsville sits 400-600 feet above sea level on the Piedmont plateau, higher than Baltimore proper, with more aggressive winter freeze-thaw cycles that crack mortar joints and spall brick. Once the clay tile cracks, flue gases and moisture migrate into adjacent flues in the same stack - a cross-contamination risk unique to Catonsville’s dense, multi-flue housing.
- Abandoned flue left open and unsealed. In attached brick homes along Frederick Road and through the Paradise neighborhood, an unused fireplace or water-heater flue often draws exhaust from a neighbor’s appliance. The homeowner smells oil or gas on still nights and doesn’t know why. We seal dead flues at the crown and document the repair with photos.
- Oversized flue from fuel conversion. Coal-to-oil-to-gas conversions left Catonsville chimneys with flues far too large for modern appliances. A flexible liner dropped without proper sizing or insulation produces poor draft, cold backdrafts, and accelerated creosote buildup. We calculate the correct liner diameter for your BTU output and venting height.
- Shared chimney stack with no separation between flues. Catonsville’s streetcar-era attached homes often have two or three clay-tile flues in a single stack with deteriorating parging between them. Exhaust from an active furnace flue can migrate sideways into an abandoned or fireplace flue, then into living space. Our Level-2 inspection finds this. Our rebuild and reline fixes it.

FAQs - Chimney Liner & Rebuild in Catonsville
Yes, it can, and we find this more often in Catonsville than in newer suburbs. The clay-tile parging between flues in these 1900s-1940s stacks deteriorates over decades, creating gaps where exhaust migrates sideways. We were called to a brick Colonial Revival off Frederick Road in the Paradise neighborhood where the homeowner kept smelling a faint oil odor on still nights. Pulling the damper and running a Level 2 inspection showed the fireplace flue shared a chimney stack with a now-gas-converted furnace flue, and an abandoned third clay-tile flue was drawing exhaust sideways into the living-space flue. We sealed the dead flue at the crown, installed a DuraFlex stainless liner sized for the furnace appliance, and the odor cleared within a day. If you smell fuel odors in your fireplace, call (410) 305-7884 - this is not a problem that fixes itself.
Most Catonsville homeowners don’t know until we show them. The original construction often included two or three separate clay-tile flues in one stack - fireplace, furnace, water heater - and only one may be in active use. During our Level-2 inspection, we run a camera up every opening and mark what we find on your photo report. You’ll see exactly how many flues exist, which are active, and whether any abandoned flues are open to moisture, debris, or neighbor exhaust. Call (410) 305-7884 to schedule - the inspection takes about an hour, and you’ll have the photos same day.
It matters more in Catonsville than in many places, and not because of fireplace use. Your chimney likely vents your furnace or water heater even if you never light a fire. A cracked liner or open abandoned flue can vent carbon monoxide into living space year-round. The National Fire Protection Association recommends annual inspection for all chimneys, vents, and flues - not just active fireplaces. In Catonsville’s older housing stock with multiple fuel conversions and shared stacks, skipping inspection means missing problems that worsen silently. Call (410) 305-7884 to book; estimates are free.
A correctly sized stainless liner will fix poor draft in an oversized flue, but sizing is the key word. Many Catonsville chimneys were built for coal furnaces with flue areas far larger than modern gas appliances need. Dropping a liner without calculating the correct diameter for your BTU output and venting height can make draft worse, not better. We measure, we calculate, we document - then we install. The result is a liner that drafts properly and meets manufacturer warranty requirements. Call (410) 305-7884 for an exact assessment of your flue.
A partial rebuild addresses the failed section - typically the crown, upper brick courses, and flue openings above the roofline - while preserving sound masonry below. In Catonsville, we use partial rebuilds where freeze-thaw damage is concentrated at the top but the stack below is structurally sound. A full chimney rebuild tears down to the roofline or foundation and rebuilds the entire structure, necessary when multiple flues are compromised, the stack is leaning, or mortar failure extends throughout. We’ll show you camera evidence of exactly what condition your chimney is in and recommend accordingly - nothing more, nothing less. Call (410) 305-7884 for a free estimate and honest verdict.
