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 Landover’s Preferred Chimney Repair Company
Landover homeowners know their chimneys. Many have lived in the same post-war ranch or split-level for twenty, thirty, even forty years. They’ve watched the neighborhood change, the boilers convert from oil to gas, and the original clay tile liners quietly age past their reliable service life. We’re the company that understands what that history means for your flue.
Our technicians are background-checked, uniformed, and trained to spot the specific failure modes hiding in Landover’s housing stock: oil-to-gas flue mismatches, freeze-thaw mortar damage on 1950s soft brick, and third-degree creosote glaze from decades of skipped service. Most repairs are completed in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Every job is backed by our 90-Day Done Right Promise, governed by the K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we make it right. In writing, no arguing.

Our Chimney Repair Services in Landover
Chimney Relining for Oil-to-Gas Conversions
This is the Chimney Liner & Rebuild - Landover repair homeowners need most and talk about least. Thousands of brick ranches in Kent Village, Landover Hills, and along Sheriff Road were built with oversized flues for oil-fired boilers. When homeowners later converted to natural gas, many of those flues were never properly relined. The result is a diameter mismatch that causes condensation, backdrafting, and a sticky sulfurous residue that modern high-efficiency gas units cannot burn off.
We install HeatShield and DuraFlex stainless steel liner systems sized precisely to your appliance. Our Level-2 camera inspection documents the existing flue condition with photos you can see, and we probe for oil-residue odor on any pre-1980 home before signing off. Done right, and we stand behind it.
Mortar Repointing & Tuckpointing
Landover’s freeze-thaw cycle is brutal on 1950s-60s soft brick and original lime mortar. Twenty-plus below-freezing nights each winter drive moisture into hairline cracks, expand it, and fracture the joints. By spring, you’re looking at spalled faces, receding mortar beds, and water paths straight to your liner.
We grind out failed joints to proper depth, match the original mortar composition, and repoint with professional-grade materials from Olympia Chimney and Copperfield. No builder-grade substitutes. The repair blends with your existing brick and restores the structural bond that keeps water out.
Chimney Waterproofing & Crown Sealing
Summer humidity in Prince George’s County promotes heavy moss and organic growth on Chimney Cap & Crown - Landover structures, accelerating cracking and letting water infiltrate already-compromised clay tile liners. We seal crowns with flexible, breathable coatings that stop water penetration without trapping vapor inside the masonry. For chimneys with significant spalling, we apply penetrating waterproofing agents formulated for porous brick.
Flashing Repair
Step flashing and counterflashing on Landover’s older ranch homes often fail where the roofline meets the chimney, particularly after decades of thermal cycling. We fabricate and install custom flashing with proper overlap and sealant integration, preventing the leaks that rot roof decks and damage interior finishes.

Trusted Brands We Service in Landover

Every component we install is spec’d for the exact demands of your appliance and flue configuration.
Common Chimney Repair Problems We See in Landover Homes
- Oil-to-gas flue mismatch in pre-1980 ranches. The original oversized clay tile flue was never relined after boiler conversion, causing condensation, backdrafting, and sulfurous odor that homeowners mistake for a gas leak. We probe for this on every older ranch call.
- Third-degree creosote glaze from decades of skipped service. High ownership turnover in Landover’s 1970s-80s demographic shifts meant chimneys went unswept for years. Compacted glazed creosote cannot be removed with standard brushing and requires chemical treatment or liner replacement.
- Freeze-thaw spalling on 1950s-60s soft brick and mortar. The DC metro’s aggressive freeze-thaw cycle fractures aging joints and spalls brick faces, opening water paths that silently destroy clay tile liners from the outside in.
- Summer humidity and moss-driven crown cracking. Heavy organic growth on chimney crowns accelerates cracking and infiltration, particularly on chimneys already compromised by missing or damaged caps.

FAQs - Chimney Repair in Landover
Your original oversized clay tile flue was never properly relined for the new appliance, so the high-efficiency gas unit produces condensation in a flue that’s too large and too cold, while the sticky sulfurous residue from years of oil burning continues to off-gas. We see this constantly in Landover’s pre-1980 ranches off Kent Village Drive and Sheriff Road. Our techs probe for oil-residue odor and flue sizing mismatch during every Level-2 inspection, then install a properly sized HeatShield or DuraFlex liner to correct the draft and eliminate the smell. Call (301) 479-9806 for a camera inspection - estimates are free.
Wood stoves used as primary heat need Chimney Cleaning & Sweep - Landover service every 1-2 cords burned, which typically means once per heating season at minimum and often mid-season if you’re burning full-time through Landover’s 20-plus below-freezing nights. Primary heat loading produces far heavier creosote accumulation than occasional fireplace use, and the EPA recommends more frequent inspection for heavy-use installations. We also counsel on burning practice - seasoned hardwood, adequate air supply, proper stove temperature - because how you burn matters as much as how often you sweep. Call (301) 479-9806 to schedule and discuss your burning habits.
Yes, and more urgently than newer construction. The soft brick and porous lime mortar used in Landover’s post-war ranches absorb moisture readily, and our humid subtropical climate delivers both heavy summer humidity and aggressive freeze-thaw cycling that fractures water-logged masonry. We recommend crown sealing and breathable penetrating waterproofing for any chimney showing moss growth, mortar recession, or spalled brick faces. The treatment typically runs $450-$950 and stops the infiltration that silently destroys liners from the outside. Call (301) 479-9806 for an assessment.
Shared party-wall chases mean a flue fire or smoke problem in one unit can quickly affect neighbors, and roofline access requires navigating tight row-roof configurations that complicate scaffolding and material handling. We’ve worked on townhome clusters throughout Landover, including developments near Landover Hills, and our technicians are experienced with the confined-space protocols and neighbor-notification practices these jobs require. The repairs themselves - repointing, relining, crown work - are similar, but the logistics demand a crew that knows the building type. Call (301) 479-9806 to discuss your specific row.
Third-degree glazed creosote can sometimes be removed with chemical treatment and mechanical brushing if the underlying clay tile liner is intact, but in Landover’s high-turnover properties where chimneys went unswept for decades, we often find the glaze has bonded to cracked or collapsed tile that no longer protects the masonry surround. Our Level-2 camera inspection shows you exactly what we’re seeing. If the liner is compromised, replacement with a stainless steel HeatShield or DuraFlex system is the only safe repair. We do not guess, and we do not sell you a liner you don’t need. Call (301) 479-9806 for a documented inspection with photos.
