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 Overlea chimneys for decades. The postwar Cape Cods and brick bungalows along Belair Road, the colonials tucked behind Fullerton Avenue, the homes up near Overlea High School - they all share the same story. Dual-flue masonry chimneys built for coal and oil, converted to gas decades ago, now venting modern appliances through flues that were never designed for them. We know what to look for because we’ve seen it hundreds of times.
Our Chimney Liner & Rebuild team doesn’t guess. Every inspection is a Level 2 camera inspection with photos you can see on our tablet, and a plain-English verdict before we quote a single dollar. No upselling. No scare tactics. Just the thing done correctly.

Our Chimney Liner & Rebuild Services in Overlea
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Overlea furnace flues that were originally sized for coal or oil and now vent natural gas. The flue is too big. The acidic condensate from modern gas appliances eats the original clay tile from the inside out. We’ve pulled out tile that crumbled at the touch in homes off Kenwood Avenue and Rossville Boulevard.
We install DuraFlex stainless steel liners, sized precisely to your appliance’s BTU output and venting requirements. A typical stainless steel liner installation in Overlea runs $2,800-$4,200 for a single flue, including the liner, top plate, and proper connector. We pull the permit if Baltimore County requires one, and we document the entire installation with photos.
Flexible Liner Systems
Some Overlea chimneys have offsets, bends, or tight clearances that make a rigid stainless liner impossible to install. Flexible liners from trusted manufacturers navigate these obstacles without compromising draft or safety. We see this often in the smaller Cape Cods near Taylor Avenue, where the chimney run is short but crooked.
Flexible liner installation in Overlea typically costs $2,200-$3,800. The price varies with length, diameter, and whether we need to remove an existing failed liner first. We always inspect with a camera before recommending flexible versus rigid - the wrong choice costs you draft efficiency and safety.
Liner Replacement & Repair
Not every flue needs a full stainless liner. Sometimes the clay tile is intact but the mortar joints have failed, or there’s isolated spalling in the smoke chamber. For these cases, we offer HeatShield liner repair - a cerfractory sealant system that restores the flue’s integrity without a full tear-out.
HeatShield liner repair in Overlea runs $1,800-$2,800 for a typical furnace flue. It’s not the right choice for every situation. We only recommend it after camera inspection confirms the tile structure is sound enough to support the sealant. You’ll see the photos. You’ll hear the verdict. Then you decide.
On a 1952 brick bungalow off Linden Avenue in Overlea, our tech ran a Level 2 inspection and found the fireplace flue had cracked clay tiles from a 1970s wood-stove insert that had been connected with a bare masonry thimble, while the adjacent furnace flue showed heavy spalling at the crown and a failed damper. We documented both flues on camera, showed the homeowner the third-degree creosote glazing in the insert flue, and installed a DuraFlex stainless steel liner sized for the wood stove after a partial rebuild of the crown and smoke chamber. The furnace flue got a HeatShield liner repair and a new chimney cap, and the homeowner could see every defect on our tablet before we quoted a single dollar.
Partial Chimney Rebuild
Overlea’s 15-20 freeze-thaw cycles per winter destroy chimney crowns. Water gets in, freezes, expands, and cracks the mortar wide open. By the time homeowners notice white efflorescence on the brick or a drip in the attic, the crown is often gone and water is attacking the smoke chamber liner from the outside.
Partial rebuilds address the crown, the top few courses of brick, and sometimes the smoke chamber - without the cost of a full teardown. In Overlea, partial rebuilds typically run $2,200-$4,500 depending on height and scaffolding needs. We use professional-grade materials from Copperfield and Famco for caps and flashing, and we match existing mortar color where we can. The goal is a repair that lasts, not a patch that buys you two years.

Trusted Brands We Service in Overlea
We don’t use builder-grade substitutes. Our trucks carry DuraFlex stainless steel liners, HeatShield cerfractory repair materials, and Famco and Copperfield caps, dampers, and flashing components. These are the brands that other chimney professionals use on their own homes. We stock common sizes locally, so most Overlea jobs don’t wait on parts. A liner job that might take a chain company two or three visits to complete, we typically finish in one day - done right, and we stand behind it.
Common Chimney Liner & Rebuild Problems We See in Overlea Homes
- Unlined or clay-tile flues cracked by acidic condensate. Overlea’s postwar chimneys were built for coal and oil. Natural gas conversions left furnace flues dramatically oversized, so exhaust cools too quickly and condenses into sulfuric acid that eats clay tile from the inside. We find this on Belair Road, on Fullerton Avenue, on Kenwood - nearly every street in town.
- Dual-flue chimneys with one good flue and one failed flue. Because both flues in these homes are aging simultaneously, one often passes a basic visual inspection while the adjacent flue has cracked tiles and failed mortar. A camera scan of both flues is essential. We’ve seen homeowners pay for a cleaning on the “good” flue while the dangerous one went untouched.
- 1970s wood-stove inserts with original flexible connectors or bare masonry thimbles. Many Overlea homeowners added inserts during the energy crisis and never had the flue properly relined. Those connectors are now 45-plus years old, often cracked or separated, and the bare masonry thimble is a code violation under current Baltimore County fire safety standards. The insert itself might work fine. The venting system is the hazard.
- Spalling crowns and cracked haunches from freeze-thaw damage. Baltimore County winters cycle hard. Water enters hairline cracks, freezes overnight, and widens them day by day. Without recent tuckpointing, Overlea chimneys show this damage universally. The cracks let water into the smoke chamber, where it accelerates liner deterioration and can reach the framing.
Pricing for Chimney Liner & Rebuild in Overlea, MD
Here’s what chimney liner and rebuild work actually costs in Overlea’s market:
| Service | Typical Range in Overlea |
|---|---|
| Stainless steel liner (single flue) | $2,800-$4,200 |
| Flexible liner system | $2,200-$3,800 |
| HeatShield liner repair | $1,800-$2,800 |
| Partial rebuild (crown, top courses, smoke chamber) | $2,200-$4,500 |
| Full chimney rebuild | $6,000-$9,000 |
| Level 2 camera inspection with photo report | $289-$349 |
Three factors move these numbers: height (two-story colonials cost more than single-story bungalows), access (tight side yards require more labor), and what we find once we’re inside. A flue with collapsed tile takes longer to clear than one with intact but cracked tile. We price this upfront, not as we go.
Every estimate includes a free camera inspection if you proceed with the work. Our $89 Seasonal Tune-Up is available for chimneys that don’t yet need relining. Seniors and veterans receive a permanent 5% discount. And if you’ve got a written estimate from another company, we’ll give you a free second opinion - we’ll run our own camera and show you what we see.

FAQs - Chimney Liner & Rebuild in Overlea
Probably, yes - and here’s why. Your 1955 flue was sized for a coal or oil furnace that ran hot and produced dry exhaust. Your modern gas furnace produces cooler, wetter exhaust that condenses in that oversized flue. The condensate is acidic, and it dissolves clay tile from the inside out. We’ve pulled intact-looking tile from 1950s Overlea chimneys that crumbled in our hands.
That said, we don’t sell liners without proof. Our Level 2 camera inspection will show you the tile condition, the flue sizing, and any deterioration. If the tile is sound and the sizing works, we’ll tell you. If it’s not, you’ll see exactly why. Call (443) 785-3816 to schedule - estimates are free.
Not until the venting system is inspected with a camera. Many Overlea inserts were connected with flexible liner connectors or bare masonry thimbles that are now 45-plus years old. The insert itself might be fine. The connector may be cracked, separated, or creosote-glazed to the point of near-blockage. Baltimore County fire safety standards have changed since 1975, and many of these installations don’t meet current code.
We inspect the entire venting path, not just the stove. If the connector needs replacement or the flue needs a stainless liner sized for the insert’s output, we’ll show you the camera evidence and quote it upfront. Don’t burn another season on guesswork. Call (443) 785-3816.
Freeze-thaw damage and water infiltration. Baltimore County’s 15-20 annual freeze-thaw cycles expand water in your chimney’s mortar joints, cracking the crown and pushing out mineral salts that leave white efflorescence on the brick face. The crack lets more water in. The cycle accelerates.
In Overlea’s 60-to-80-year-old chimneys, this is nearly universal without recent tuckpointing. The real concern is where that water goes - into the smoke chamber, down the flue, sometimes into the framing. A partial rebuild of the crown and top courses, combined with proper capping and flashing, stops the cycle. We’ll show you the extent on camera before quoting. Call (443) 785-3816 for a free estimate.
Once per year, per NFPA 211 - regardless of use frequency. Occasional burning actually creates more risk than regular use because the flue never gets hot enough to dry out creosote deposits. In Overlea’s humid mid-Atlantic summers, that creosote hardens into glazed deposits that are extremely difficult to remove and highly combustible.
For occasional burners, we recommend scheduling in early fall before the burning season starts. Our $89 Seasonal Tune-Up includes inspection and basic cleaning. If we find glazed creosote or liner damage, we’ll show you on camera and discuss options. Call (443) 785-3816 to book.
Sometimes, but not always - and we won’t promise it until we’ve seen what we’re working with. A straightforward stainless steel liner installation on a single flue with good access and no collapsed tile? Often yes, we can inspect in the morning and install in the afternoon. A dual-flue chimney with one collapsed flue, a failed crown, and a 1970s insert connector to remove? That’s a two-day job, and we’ll tell you that upfront.
We carry common liner sizes and HeatShield materials on our trucks, so most Overlea jobs don’t wait on parts. The inspection always comes first. No work is sold without camera evidence you can see. Call (443) 785-3816 to schedule - we’ll give you a realistic timeline after we look inside.
