Fast, Reliable Chimney Repair Across Lanham-Seabrook
Most chimney repair in Lanham-Seabrook runs between $250 and $1,800 depending on whether you need mortar repointing, brick replacement, or a partial rebuild, and our Chimney Repair crew completes most jobs in a single visit with upfront pricing confirmed before we start. We’ve been driving to 20706 since 1984, and we know the Cape Cods along Annapolis Road, the split-levels near Seabrook Station, and the ranch homes tucked behind Lanham’s older commercial corridors. Prince George’s County’s freeze-thaw cycle hits these chimneys harder than homeowners expect. When mortar starts turning to powder or bricks begin flaking, call (844) 803-1545. A live person answers, and we’ll give you a free estimate with photos you can see and a plain-English verdict.
Why Hearthstone Chimney Co. Is Lanham-Seabrook’s Preferred Chimney Repair Company
We’ve worked on chimneys in Lanham-Seabrook for more than four decades. That longevity matters because the same post-WWII housing stock that gives this area its character also creates repair patterns we’ve seen hundreds of times. Our technicians know which 1950s Cape Cods near the Seabrook MARC station have chimneys originally built for oil furnaces, and they know what to look for when the flue was never properly resized for gas conversion.
Our customers in 20706 call back because we document every inspection. You get photos of your mortar joints, your crown, your liner condition, and a written verdict you can understand without a code book. The 90-Day Done Right Promise backs every repair in writing, no arguing. If it’s not right, we come back.
Calls are answered by a live person 24 hours a day, 7 days a week. Not a voicemail, not a callback queue.

We’ve earned a strong local reputation in Prince George’s County by doing the job correctly and standing behind it.
Our Chimney Repair Services in Lanham-Seabrook
Mortar Repointing
The freeze-thaw cycle in Lanham-Seabrook grinds away mortar faster than inland Maryland. We’ve repointed chimneys on ranch homes near Greenbelt Road where the original 1960s mortar had turned to sand. Our crew grinds out failed joints to proper depth and packs new mortar matched for color and compressive strength. Done right, repointing adds decades to a chimney’s life.
Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is everywhere we look in 20706 after hard winters. The Mid-Atlantic humidity from Chesapeake Bay proximity keeps brick saturated longer, so when January temperatures plunge and rebound, the damage accelerates. We remove spalled bricks and install matching replacements, or we rebuild chimney sections when the structural wythe is compromised. In Lanham-Seabrook’s older stock, we often find spalling concentrated on the south and west exposures where sun and wind drive moisture deeper.
Chimney Waterproofing
Waterproofing a chimney in Lanham-Seabrook requires breathable sealants that won’t trap moisture already in the brick. We apply professional-grade treatments after repairs are complete, concentrating on the crown wash and the interface where brick meets flashing. Homes near the wooded sections of Seabrook, where tree cover slows drying, benefit especially from this protection.
Flashing Repair
Step flashing and counterflashing around chimney penetrations fail predictably in Lanham-Seabrook’s older homes. The original galvanized flashing on many 1950s and 1960s roofs has corroded, and previous repairs often used caulk as a substitute for proper metalwork. We fabricate and install new flashing that integrates correctly with your roofing system, sealed with professional-grade materials from Copperfield and Famco.

Trusted Brands We Service in Lanham-Seabrook
We stock parts and materials from Olympia Chimney, Famco, and Copperfield, so Lanham-Seabrook homeowners aren’t waiting on special orders for standard repairs. When we find a deteriorated liner in a converted oil-to-gas system, we can often source DuraFlex stainless steel relining pipe and have it installed within days, not weeks. Our relationships with these manufacturers mean warranty coverage travels with the work, and our technicians are trained on proper installation for each product line. No builder-grade substitutes, no improvising with what fits.
Common Chimney Repair Problems We See in Lanham-Seabrook Homes
- Oversized, unlined flues from oil-to-gas conversions. Technicians in 20706 regularly find brick chimneys serving gas furnaces with no clay tile liner at all. The original liner was never updated when the oil furnace was swapped out, leaving a bare brick flue that accumulates sulfurous condensate and is out of compliance with both NFPA 211 and Prince George’s County mechanical permit requirements.
- Interior mortar deterioration hidden from view. Chimney cleaning visits here routinely uncover not just creosote but active liner deterioration that a gas-only homeowner never suspected because “the heat still works fine.” Acidic condensate eats mortar from the inside out, weakening the structure before any exterior warning appears.
- Spalling and joint failure from freeze-thaw cycling. Prince George’s County’s hard freezes followed by rapid January and February thaws drive brick damage faster than in colder but more stable climates. The regional humidity from Chesapeake Bay proximity keeps brick wetter between cycles, accelerating the damage every sweeping season.
- Crown cracks that funnel water into the flue. Concrete crowns on Lanham-Seabrook’s mid-century chimneys were often poured too thin or without proper overhang and drip edge. Once cracked, they become a direct path for water to saturate the flue and damage interior components.
