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 Chillum’s Preferred Fireplace Services Company
We’ve served communities across Prince George’s County for over 42 years, and Chillum’s particular mix of post-war brick colonials and Cape Cods has taught us what the chains and one-truck operators miss. The 1940s-to-1960s housing stock here, much of it built when coal or fuel-oil heat was standard, means chimneys that have been through multiple fuel conversions without matching flue upgrades. We document every inspection with a Level-2 camera scan, show the homeowner the photos, and deliver a plain-English verdict before any work is discussed.
Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back, no paperwork and no arguing. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it. Our technicians are background-checked, uniformed, and complete most repairs in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Calls are answered by a live person, every hour of every day. Not a callback queue. Not an app.
Our Fireplace Services in Chillum
Gas Fireplace Service
Chillum’s gas fireplaces are often vented through chimneys originally built for coal or oil furnaces - oversized, unlined, or lined with deteriorated clay tile. That mismatch produces condensation, poor draft, and corrosion that a basic cleaning won’t address. We inspect with a camera, check gas pressure and burner alignment, and verify that the flue is properly sized for the appliance. If the flue is failing, we’ll show you the footage and explain whether a liner from DuraFlex or HeatShield is warranted.
Wood Burning Fireplace
Wood burning in Chillum’s older homes demands extra attention to creosote buildup and flue integrity. The freeze-thaw cycles here - wet winters with temperatures oscillating through freezing repeatedly - accelerate deterioration in chimneys that have already served 60-plus years. We check for third-degree creosote, cracked crowns, and spalling brick that could compromise the firebox or adjacent structures. Our Fireplace Services team documents everything with photos you can see.
Fireplace Insert
Inserts are popular in Chillum’s compact mid-century homes because they add efficiency without requiring a full rebuild. But an insert installed into a damaged or improperly lined flue is a fire and carbon monoxide hazard. We measure the flue, inspect with a camera, and specify the correct liner size before any insert goes in. Most of our Chillum insert installations use Olympia Chimney or DuraFlex components, sized to the appliance and documented with a photo report.
Damper Repair
Chillum’s 1960s fireplaces often have original throat dampers that have corroded, warped, or jammed with creosote and debris. A stuck damper wastes heat, invites drafts, and can prevent proper venting if a fire is lit. We assess whether the damper can be repaired or needs replacement, and we check the smoke chamber and flue above it - because in these older homes, damper problems are frequently a symptom of deeper deterioration.
Firebox Repair
The firebox in a Chillum brick colonial takes decades of direct heat, and the original refractory panels or mortar joints often crack or spall. We rebuild with professional-grade materials, matching the original construction where possible and upgrading with HeatShield or Gelco products when the damage warrants. Every repair is photographed before and after, with a written verdict explaining what was done and why.
Fireplace Conversion
Converting a wood fireplace to gas - or updating an old gas setup - is common in Chillum, but the existing flue is rarely ready. Many of these chimneys were built for coal or oil and later adapted without proper lining, leaving an oversized flue that condenses moisture and fails to draft correctly. We never recommend a conversion without a Level-2 camera inspection that you can watch on our monitor. If a new liner is needed, we specify it with exact measurements and show you why.
Trusted Brands We Service in Chillum
We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - not builder-grade substitutes that fail early. For Chillum homeowners, that means faster turnaround because we don’t wait on special orders for standard components. A firebox repair with HeatShield cerfractory foam, a DuraFlex stainless liner for a gas conversion, or an Olympia Chimney cap for a cracked crown: we carry the parts, we know how they perform in our local climate, and we back the installation with our 90-Day Done Right Promise.
Common Fireplace Services Problems We See in Chillum Homes
- Unlined or clay-tile flues mismatched to gas appliances. Chillum’s chimneys were built for coal or oil, and many still vent gas furnaces or fireplaces through oversized, deteriorated clay tiles. The condensation and poor draft this causes won’t be solved by sweeping alone - the camera tells the real story.
- Cracked crowns and open mortar joints accelerating freeze-thaw damage. Our DC-area winters oscillate through freezing repeatedly, and moisture that has infiltrated 60-year-old masonry expands with every cycle. Each winter widens the voids, and by spring the crown is shedding debris.
- Spalling brick and mortar dropping onto adjacent rooftops. Chillum’s tight lots and closely spaced party walls mean a single deteriorating chimney crown often becomes a neighbor-liability issue. We’ve fielded calls from homeowners on 62nd Avenue and nearby streets whose roofs were hit by debris from next door.
- Third-degree creosote in shared or multi-appliance chimneys. When chimneys vent multiple appliances or sit close to party walls, creosote buildup or loose debris can affect adjacent properties. A Level-2 inspection with camera documentation protects you and documents the condition for your records.

FAQs - Fireplace Services in Chillum
Yes. Chimneys from this era were typically built for coal or oil and later converted to gas, leaving unlined or clay-tile flues that are now past their service life. A Level-2 inspection with a camera scan is the only way to verify that the flue is safe for your current appliance. We show you the footage on our monitor and explain what we see in plain English before recommending any work. Call (301) 479-9806 to schedule - estimates are free.
Third-degree creosote appears as a thick, tar-like, or hardened glaze inside the flue, and it cannot be removed by standard brushing alone. If you burn wood regularly and notice reduced draft, a smoky smell even when the fireplace is cold, or visible black buildup at the damper, you likely have it. We diagnose with a camera inspection and remove it with mechanical tools or chemical treatment as needed. Call (301) 479-9806 for an inspection - estimates are free.
This is a common problem in Chillum’s tightly packed post-war neighborhoods, where closely spaced party walls let one deteriorating chimney affect multiple properties. The neighbor needs a camera inspection to assess crown and masonry condition, followed by crown repair or replacement and possibly repointing. We document the condition with photos that can be shared with your neighbor or their insurer, and we handle the repair with materials that withstand our local freeze-thaw cycle. Call (301) 479-9806 - we can inspect and provide a written verdict.
Nearly always, yes. The original flue was sized for a coal or oil appliance, and modern gas inserts or logs require a correctly sized, properly sealed liner to vent safely and efficiently. We measure and inspect with a camera before specifying the liner - typically DuraFlex stainless steel or HeatShield cerfractory depending on the application. Nothing is installed without camera evidence you can see. Call (301) 479-9806 for a free estimate.
Original throat dampers in Chillum’s mid-century homes corrode, warp, or jam with decades of creosote and debris. The mechanism may be rusted, the frame may have shifted as the firebox settled, or the smoke chamber above may be partially blocked. We inspect the damper, the smoke chamber, and the flue with a camera to find the root cause. Repair or replacement is usually completed in a single visit. Call (301) 479-9806 - estimates are free.
On a call near 62nd Avenue in Chillum, our tech found an original clay-tile flue serving a converted gas furnace - the tiles were spalled and the mortar joints had failed, allowing water to reach the smoke chamber. We ran a camera the homeowner could watch on our monitor, showed the cracked crown and failed damper, then installed a HeatShield liner and poured a new crown - no upsell beyond what the camera proved.
