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 driving to Chillum since the early 1980s, and we’ve learned the chimneys here. The brick colonials and Cape Cods off Riggs Road, the semi-detached rows near Chillum Road, the tight lots along Sargent Road - these are not generic suburban chimneys. They were built for coal and fuel-oil furnaces in the 1940s through 1960s, then converted to gas decades later, and now they’re running on borrowed time. Our Chimney Liner & Rebuild team knows what to look for, and we document every finding with a camera so you see what we see before any work is discussed.
Dispatch and scheduling are coordinated from our Washington, DC office, but our crews live and work in Prince George’s County. That means we’re not guessing about Chillum’s freeze-thaw cycles, its tight party-wall lots, or the way a 1955 brick chimney behaves after sixty years of service. We show up when we say we will, we explain the repair in plain English, and we back it with the 90-Day Done Right Promise - in writing, no arguing.

Our Chimney Liner & Rebuild Services in Chillum
Stainless Steel Liner Installation
Stainless steel liners are the right fix for most Chillum chimneys that were converted from oil or coal to gas. The original flue was sized for a furnace that ran hot and drafted hard; a modern gas appliance runs cooler and produces more moisture. An oversized, unlined flue lets that moisture condense on the masonry, eating mortar joints from the inside. We install DuraFlex and Olympia Chimney stainless liners sized precisely to your appliance, with proper insulation to prevent condensation and improve draft. A typical stainless liner installation in Chillum runs $2,800-$4,200.
Flexible Liner Installation
Some of Chillum’s older chimneys have offsets or bends that a rigid liner won’t navigate, especially in the semi-detached homes with shared flue structures. Flexible liners from trusted manufacturers allow us to thread a proper venting path without dismantling the chimney. We see this need often in the Cape Cods near Chillum Road, where the original construction left tight turns. Flexible liner installation in Chillum typically costs $2,400-$3,800.
Liner Replacement
This is where Chillum homeowners get sold work they don’t need. Clay tile liners do fail after 50-plus years, but they don’t always need wholesale replacement. Our Level 2 camera inspection shows you exactly what condition your flue is in - cracked tiles, missing mortar between joints, glazed creosote, or an unlined stack that was never meant for your current appliance. If replacement is warranted, we remove the damaged material and install a new stainless or flexible liner with proper clearances and insulation. Liner replacement in Chillum generally runs $2,600-$4,500. You watch the camera footage before we quote anything.
Partial Rebuild
Chillum’s freeze-thaw cycle is brutal on 60-year-old masonry. Water seeps into cracked crowns and open mortar joints, freezes, expands, and widens the damage until brick faces pop off and land on the roof below. On tight Chillum lots with party walls, that’s not just your problem - it’s your neighbor’s liability claim waiting to happen. A partial rebuild addresses the damaged section, typically from the roofline up, with matching brick and proper crown construction. Partial rebuilds in Chillum range from $3,500-$6,000 depending on height and accessibility.
Full Chimney Rebuild
When the structural integrity is compromised throughout - multiple courses of spalled brick, deteriorated firebox, failed foundation - a full rebuild is the only safe option. This is less common in Chillum than partial rebuilds, but we’ve done them on homes where decades of deferred maintenance finally caught up. Full rebuilds start around $7,500 and are completed with proper permits and inspections.
Liner Repair and Resurfacing
Not every damaged liner needs replacement. HeatShield cerfractory resurfacing can restore a clay flue with minor cracking or joint gaps, provided the structural shell is sound. This is often the right call for Chillum chimneys where the clay tile is cracked but not collapsed, and where the homeowner wants to preserve the original construction. Resurfacing runs $1,800-$2,800 in Chillum and carries the same 90-Day Done Right Promise as our full replacements.

Common Chimney Liner & Rebuild Problems We See in Chillum Homes
- Oversized flues mismatched to gas appliances. Your 1955 chimney was built for a coal furnace that drafted 400°F exhaust. Your new gas furnace runs cooler and wetter. The flue is too big, the exhaust moves too slow, and condensation soaks into the masonry. We see this on nearly every cleaning call in Chillum’s post-war neighborhoods.
- Freeze-thaw destruction of crowns and mortar. Chillum’s winters oscillate above and below freezing dozens of times each season. Water enters through hairline cracks, freezes overnight, and opens gaps that let in more water. By spring, the crown is crumbling and brick faces are spalling onto the roof - or the neighbor’s roof, on tight lots.
- Third-degree creosote from the coal and oil era. Before your furnace was converted to gas, it may have burned fuel oil for decades. That left glazed, rock-hard creosote that a standard brush won’t remove. Too many companies see this and immediately sell a liner replacement. We document it with the camera first, then explain your actual options.
- Spalling brick shedding onto adjacent properties. On Chillum’s closely spaced lots, a deteriorating chimney crown doesn’t just damage your home. Brick debris lands on the neighbor’s roof, in their gutters, on their driveway. We’ve handled cases where the neighbor’s first call was to their insurance agent. A partial rebuild stops the damage and the liability.

What moves the number? Height and accessibility matter - a two-story colonial on a tight lot takes longer than a single-story Cape Cod. The condition of the existing flue affects whether we can reline or must remove. And matching original brick for a partial rebuild adds material cost if the brick is no longer manufactured. We give you one number before work starts, and that’s the number on the invoice. Estimates are free, and every estimate includes the Level 2 camera inspection and photos.
Our current offers include $50 off any repair over $250, a free second opinion on any written estimate, an $89 seasonal tune-up, and a permanent 5% senior and veteran discount. Call (301) 479-9806 to schedule.

FAQs - Chimney Liner & Rebuild in Chillum
Not necessarily. Many Chillum chimneys were converted without proper relining, but that doesn’t automatically mean you need a new liner today. The critical question is whether your current flue is intact, properly sized for your appliance, and venting safely. Our Level 2 camera inspection shows you the actual condition of your flue tiles, any creosote buildup from the oil-burning years, and whether condensation is damaging the masonry. We’ve seen 1950s chimneys that need immediate relining, and we’ve seen others where a thorough cleaning and crown repair are sufficient. You watch the footage before we recommend anything. Call (301) 479-9806 for a free inspection and exact quote.
The DC-area freeze-thaw cycle is the main culprit, and Chillum’s 60-plus-year-old crowns were built with mortar mixes less resistant to water penetration than modern materials. Water enters hairline cracks, freezes overnight, and expands - each cycle widens the crack. By the time you notice it from the ground, water has likely reached the brick below. We replace failed crowns with poured concrete or pre-formed crowns sloped to shed water, with proper overhang and drip edge to protect the masonry beneath. Crown replacement in Chillum typically runs $800-$1,400. Call (301) 479-9806 to schedule an inspection.
A partial rebuild addresses damage from the roofline up - typically the crown, several courses of spalled brick, and deteriorated mortar. A full rebuild removes and reconstructs the entire chimney structure, including the firebox and foundation, when the damage is systemic. Most Chillum chimneys we see need partial rebuilds; the masonry below the roofline is often sound if the crown was the entry point for water. The camera inspection and exterior evaluation tell us which applies to your home. We never recommend a full rebuild when a partial will do. Call (301) 479-9806 for an assessment and honest recommendation.
Yes, and it’s one of the most misdiagnosed conditions we encounter in Chillum’s post-war housing stock. Third-degree creosote is a hard, glazed deposit that forms when oil or coal burns at low temperatures over long periods - exactly how 1950s furnaces often operated. A standard brush won’t remove it, but that doesn’t mean you automatically need a $4,000 liner. Sometimes mechanical removal is possible; sometimes the flue is damaged underneath and relining is warranted. We document the extent with the camera, explain what we’re seeing, and quote only what’s necessary. Call (301) 479-9806 for a free second opinion if another company already recommended replacement.
Document the damage with photos and notify your neighbor in writing - this is a liability issue that their homeowner’s insurance may need to address. Then call us for an independent evaluation of your own chimney, because the same conditions causing their spalling brick may be affecting yours. On Chillum’s tight lots with party-wall construction, we’ve seen multiple adjacent chimneys fail within a few years of each other. We inspect your crown, mortar joints, and flue condition, then give you a plain-English verdict with photos you can use for insurance or neighbor discussions if needed. Call (301) 479-9806 - estimates are free.
