We’ve been dispatching crews to Garrison from our Baltimore office for decades. The brick colonials and Cape Cods built here in the 1950s through 1970s - many along the Green Spring Valley corridor and surrounding neighborhoods - hold up structurally, but their original clay tile flue liners and mortar jointing are now fifty to seventy years old. That’s not a guess. We see it in inspection after inspection. When a Garrison homeowner switches to a wood-burning insert or converts a lower fireplace to gas logs while keeping the upper one wood-burning, the original flue sizing and shared-flue arrangements common in these homes become genuine safety hazards. Our Chimney Liner & Rebuild team handles this exact scenario regularly.

Why Hearthstone Chimney Co. Is Garrison’s Preferred Chimney Liner & Rebuild Company

We’ve served Baltimore County communities for over 42 years, and Garrison’s housing stock is familiar territory. The large multi-story colonials with two or more masonry fireplaces, the original mortar now past its service life, the chimneys originally sized for coal or oil appliances - we’ve documented hundreds of these conditions in writing with photos the homeowner can see.

Our Level 2 camera inspections end with a plain-English verdict, not a sales pitch. If the liner can be repaired, we say so. If it needs replacement, we show you the cracked or spalled clay tile on screen before we quote. The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.

A live person answers our phones 24 hours a day, 7 days a week. Not voicemail. Not a callback queue. Our background-checked, uniformed technicians complete most liner and rebuild jobs in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.

We know the local permitting landscape. Baltimore County requires proper liner sizing and separation for multiple appliances, and our documentation satisfies both code enforcement and insurance underwriters. That’s worth something when you’re selling a home on one of Garrison’s established streets.

Stainless Steel Liner Installation

For most Garrison homes with deteriorated clay tile, we install insulated stainless steel liners from DuraFlex, sized precisely to the appliance they’re serving. This matters especially here. Because Garrison’s 1950s-1970s brick colonials were often built with a single central masonry chimney serving two or more fireplaces plus a furnace or water heater flue, Baltimore County code and common sense both demand that each flue get its own correctly sized liner. A shared-flue arrangement common in these homes is where most carbon-monoxide and draft complaints originate. We recently relined a two-flue chimney on a large brick colonial near the Green Spring Valley corridor after a Level 2 inspection found spalling clay tiles and a badly undersized flue serving a wood-burning insert. The homeowner had already switched the lower fireplace to gas logs and added the insert upstairs, leaving the original 8×8 tile to handle far more heat and volume than it was sized for. We installed an insulated DuraFlex stainless liner sized to the insert’s outlet, replaced the rusted damper with a top-sealing model from Olympia Chimney, and rebuilt the chimney crown so the annual inspection cycle wouldn’t keep catching moisture intrusion.

Flexible Liner Solutions

Some Garrison chimneys have offsets or bends that rigid stainless can’t navigate - particularly in the older Cape Cods with tighter flue passages. Flexible liners from trusted manufacturers allow us to thread a proper venting path without breaking into walls. We still insulate and properly terminate at the crown. The flexible option doesn’t mean a lesser install. It means the right material for the geometry.

Liner Replacement

When clay tiles have spalled, cracked, or shifted from decades of thermal cycling and Baltimore’s humid summers, patching is temporary at best. Full liner replacement gives each appliance its own dedicated, correctly sized venting path. For Garrison homeowners with multiple fireplaces, this often means two or three separate liners in what was originally a single chimney structure. We document the before condition with camera footage, install to NFPA 211 standards, and leave you with photos of the completed work.

Partial Rebuild

Not every failing chimney needs to come down to the roofline. In Garrison, we frequently perform partial rebuilds: replacing a deteriorated crown, repointing mortar joints from the roof up, and rebuilding the top few courses of brick while preserving sound masonry below. This is cost-effective when the lower chimney structure is solid but the crown has cracked and allowed water to saturate the upper courses. We use professional-grade crown repair materials from HeatShield and Gelco, matched to the existing brick color where possible.

Full Chimney Rebuild

When spalling brick, compromised structural integrity, or widespread mortar failure extends below the roofline, a full rebuild becomes necessary. This is more common in Garrison’s chimneys that have never had proper crown maintenance or where original coal-era construction left the masonry vulnerable to decades of moisture penetration. We rebuild with matching brick, proper flue separation, and new liners sized to current appliances. The 90-Day Done Right Promise covers the complete assembly.

Trusted Brands We Service in Garrison

We don’t use builder-grade substitutes. Our Garrison jobs specify professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that stand behind their products the way we stand behind our work. We stock common liner diameters and crown repair materials locally, so most Garrison homeowners aren’t waiting on special orders. When we inspect your chimney and identify the needed repair, we can usually schedule the work promptly rather than leaving you with a cold fireplace and an open work order.

Common Chimney Liner & Rebuild Problems We See in Garrison Homes

• Spalled or cracked clay tile liners. Original clay tile liners in Garrison’s 1950s-1970s colonials have often spalled or cracked from decades of seasonal heating and Baltimore’s humid summers, so a brush-and-vacuum sweep alone leaves the chimney unsafe for a modern insert. The damage is visible on camera but invisible from the firebox.
• Shared flues and incorrect sizing. Homes with two or more fireplaces frequently share a single flue or have flues sized for coal or oil, so a wood insert or gas conversion produces draft problems and third-degree creosote glaze that standard sweeping cannot remove. Each appliance needs its own correctly sized liner.
• Glazed creosote from seasonal burst use. Stop-and-start seasonal use in Green Spring Valley estate-style homes creates rapid glazed creosote buildup, and many Garrison chimneys have never had a Level 2 inspection, meaning hidden liner and smoke chamber defects go undetected for years. The fireplace works fine until it doesn’t.
• Crown and mortar failure compounding liner damage. Garrison’s freeze-thaw cycles and humid summers accelerate crown cracking, which lets water saturate the masonry and deteriorate clay tiles from the outside in. By the time you notice water in the firebox, the liner and surrounding brick may both need attention.
