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.

Why Hearthstone Chimney Co. Is Randallstown’s Preferred Fireplace Services Company
We’ve been serving Baltimore County communities for over 42 years, and Randallstown’s particular chimney problems are familiar territory. The 1960s-70s tract housing that dominates this area, from the neighborhoods off Liberty Road to the brick colonials near Winands Road and the ranchers along Marriottsville Road, presents a specific failure pattern we’ve documented hundreds of times: clay-tile flues originally sized for oil-burner exhaust, later converted to gas without proper stainless steel relining, now deteriorating from the inside out.
Our Fireplace Services team doesn’t guess. Every inspection includes a Level-2 camera run with photos you can see on the tablet, a plain-English verdict, and a written estimate with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Our 90-Day Done Right Promise is backed in writing with no arguing. If it’s not right, we come back. Background-checked, uniformed technicians. Most jobs completed in a single visit. And a live person answers the phone every hour of every day, not a voicemail queue.
Our Fireplace Services in Randallstown
Gas Fireplace Service
Gas fireplaces in Randallstown’s older homes often sit in masonry fireboxes never designed for them, venting through flues that were originally built for oil furnaces. The result is chronic moisture problems, failed pilot lights, and corroded burner assemblies. We service all major gas fireplace brands, test gas pressure and combustion, inspect the venting path with a camera, and replace worn components with professional-grade parts. If your flue is oversized for the gas appliance, we’ll show you the footage and explain why a proper liner insert matters for safe operation.
Wood Burning Fireplace
Randallstown’s mature trees mean plenty of homeowners still burn wood, but the original clay flue tiles in these 50-70 year old chimneys are often cracked, spalled, or separated at the joints. Our wood burning fireplace service includes a full Level-2 inspection, creosote evaluation, and firebox condition assessment. We document everything with photos. If the flue needs relining, we size DuraFlex stainless inserts to the appliance, not to the old oversized flue. No work is recommended without camera evidence you can see for yourself.
Fireplace Insert
Inserts are one of the smartest upgrades for Randallstown’s aging fireplaces, especially in homes where the original masonry firebox is cracked or the flue is no longer safe. We measure your firebox, match the insert to your heating needs, and install a proper stainless liner from the insert collar to the top of the chimney. Our technicians work with professional-grade brands including Olympia Chimney and DuraFlex for liner systems, and we handle the full installation, including any necessary firebox repair and damper modification. Most insert installations are completed in a single day.
Damper Repair
A stuck or rusted damper wastes heat and can prevent proper draft. In Randallstown’s humid summers and freeze-thaw winters, cast-iron throat dampers in 1960s-70s chimneys seize, warp, or corrode. We repair or replace throat dampers and install top-sealing dampers from Famco when the original is beyond saving. A top-sealing damper also keeps rain and animals out of a flue that’s already struggling. We show you the problem on camera before quoting any repair.
Firebox Repair
The firebox is where the fire lives, and in Randallstown’s older homes, the refractory panels or original brick are often cracked, spalled, or heat-damaged after decades of use. We replace refractory panels, repoint firebox brick with heat-resistant mortar, and rebuild when necessary. Every repair is documented with before-and-after photos, and we stand behind our firebox work with the 90-Day Done Right Promise.
Fireplace Conversion
Converting a wood fireplace to gas, or updating an old gas setup to a modern direct-vent or vent-free insert, requires more than dropping in a new appliance. In Randallstown’s oil-to-gas conversion history, the chimney itself is often the limiting factor. We run a full camera inspection, verify flue sizing and condition, and only then recommend the right conversion path. If the flue needs relining or the firebox needs repair to accommodate the new appliance, you’ll see exactly why before any work begins.
Trusted Brands We Service in Randallstown
We don’t use builder-grade substitutes. Our fireplace service work in Randallstown relies on professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, the same brands specified by manufacturers and trusted by sweeps who plan to be in business thirty years from now. We stock common parts locally for faster turnaround on repairs, and we source liner systems and components sized to your specific appliance and flue, not generic close-enough fits. When we recommend a brand or part, it’s because it meets the spec for your fireplace and chimney, not because it’s what we had on the truck.
Common Fireplace Services Problems We See in Randallstown Homes
- White efflorescence on exterior brick. That chalky white staining you see on Liberty Road corridor chimneys is minerals left behind as moisture migrates through deteriorating mortar. It’s often the first visible sign that a clay flue tile is cracked or separated inside, allowing exhaust gases to condense in the masonry. By the time it shows on the outside, the inside damage is usually significant.
- Gas fireplace that won’t stay lit or drafts poorly. In Randallstown’s converted oil-to-gas chimneys, the flue is frequently oversized for the cooler gas exhaust. The draft never establishes properly, the pilot flame starves for oxygen, and moisture condenses inside the flue, accelerating corrosion. A camera inspection reveals whether the problem is the appliance, the venting, or the flue itself.
- Cracked or spalling firebox brick or panels. Decades of thermal cycling in 1960s-70s masonry fireboxes take their toll. We regularly find cracked refractory panels, missing mortar, and heat-damaged brick in Randallstown homes where the fireplace has seen heavy winter use. These defects can allow heat transfer to combustible framing, a genuine safety issue that camera inspection and firebox evaluation catch early.
- Deteriorated chimney crown and mortar joints from freeze-thaw cycling. Baltimore County winters cross 32°F repeatedly through December to March. Water enters hairline cracks in the crown, freezes, expands, and opens pathways for more water. That water reaches the flue liner, accelerates clay tile spalling, and can damage the smoke chamber. Annual inspection catches crown and mortar problems before they cascade into flue failure.

FAQs - Fireplace Services in Randallstown
Yes. Clay flue tiles in 50-70 year old chimneys separate at the joints and spall, but this failure is invisible from the firebox or rooftop until a camera is run. The National Fire Protection Association recommends Level-2 inspection for any chimney serving a changed or replaced appliance, which includes most Randallstown homes that converted from oil to gas. We document the full flue, smoke chamber, and firebox with photos you can see, then explain what we’re looking at in plain English. Call (410) 305-7884 to schedule - estimates are free.
The white staining is efflorescence, minerals deposited by moisture moving through deteriorating mortar. In Randallstown’s 1960s-70s housing stock, it frequently signals an oversized, unlined flue venting gas exhaust - the cooler gases condense inside the clay tile, moisture migrates outward, and the flue deteriorates from the inside. If your home shares the same construction era and conversion history, the same failure mode may be developing unseen. A Level-2 camera inspection reveals whether your flue is intact or showing the early stages of this pattern. Call (410) 305-7884 and we’ll show you exactly what’s inside your chimney.
It may. Oil-burner flue gases are hot and dry; gas exhaust is cooler and wetter. A flue sized for oil stays wet with gas exhaust, corroding mortar and spalling clay tile from the inside. Many Randallstown conversions were done without the stainless steel liner insert now required by code. We run a camera to verify flue condition and measure sizing against your current appliance. If relining is needed, we show you the footage and explain why; if the flue is sound, we say so. No recommendation without evidence you can see. Call (410) 305-7884 for a free evaluation.
First-degree creosote is light, flaky soot that brushes off easily during standard cleaning. Third-degree creosote is hardened, tar-like, and often glazed to the flue wall; it requires specialized removal and is more common in Randallstown fireplaces that are burned slowly or with unseasoned wood, or in flues with poor draft from oversized or damaged liners. Third-degree creosote is also the most combustible form and the leading cause of chimney fires. During our inspection, we classify what we find and document it with photos. If you have third-degree buildup, we’ll explain the removal process and whether your burning habits or flue condition are contributing. Call (410) 305-7884 to schedule.
The National Fire Protection Association recommends annual inspection for all chimneys, fireplaces, and venting systems. In Randallstown, we consider this especially important given the age of the housing stock and the freeze-thaw cycling that accelerates mortar and flue deterioration. An annual Level-1 or Level-2 inspection catches spalled flue tiles, separated joints, and crown damage before they become safety hazards or expensive repairs. If you burn wood regularly, annual sweeping is also advised. We don’t upsell inspections you don’t need, and we’ll tell you plainly if your system looks sound for another season. Call (410) 305-7884 to book.
