We answer calls with a live person 24 hours a day at (844) 803-1545, and our technicians are usually on Severn roads within the hour for urgent cases.

Why Hearthstone Chimney Co. Is Severn’s Preferred Chimney Repair Company
Severn sits in a pocket of Anne Arundel County where the housing boom of the 1970s and 1980s left thousands of homes with prefab metal fireplaces now pushing 40 to 50 years of age. We’ve worked on enough of them to know the failure patterns by sight: the cracked refractory panels, the corroded fireboxes, the chase covers that have been leaking since the last homeowner moved out. Our Level-2 camera inspections and Chimney Cleaning & Sweep - Severn services end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman.
Our reputation in 21144 and surrounding zip codes is built on showing up when we say we will and standing behind the work. The 90-Day Done Right Promise governs every job, backed in writing with no paperwork and no arguing. If it’s not right, we make it right. Calls are answered by a live person, 24/7, not a callback queue. Our background-checked, uniformed technicians carry professional-grade materials from Olympia Chimney, Famco, and DuraFlex on every truck, so most repairs finish in one visit without waiting on parts.
We also handle Fireplace Services in Severn and Chimney Cap & Crown in Severn when your project crosses into those areas.
Our Chimney Repair Services in Severn
Mortar Repointing
The freeze-thaw cycles that roll off the Chesapeake Bay hit Severn’s older brick chimneys hard. Water seeps into hairline mortar cracks in October, expands through winter, and by March the joints are crumbling. Repointing in Severn typically costs $800-$2,200 for a standard chimney, depending on accessibility and how many courses need grinding out. We use color-matched mortar and tooled joints that blend with your existing brickwork, not slapped-on patches that stand out from the street.

Spalling Brick Repair
Spalling, the flaking and popping of brick faces, is common on Severn chimneys where decades of moisture intrusion have compromised the masonry. Homes near the Severn Run watershed see this particularly on north-facing exposures where sun never fully dries the brick. Repair ranges from $450 for localized patching to $1,800 for rebuilding several courses. We source matching brick when possible, or recommend full rebuild sections when the structural integrity is gone.

Chimney Waterproofing
Severn’s humid summers and bay-influenced precipitation patterns make waterproofing a smart investment, not an upsell. We apply vapor-permeable sealers from professional-grade lines that let the chimney breathe while blocking liquid water, critical in this climate where trapped moisture accelerates deterioration. A typical waterproofing treatment runs $350-$650 and carries a 10-year performance warranty. For homes in the 21144 area with prefab chimneys, we also waterproof chase structures and replace deteriorated chase covers that cheaper operators often miss.

Flashing Repair
The step flashing where your chimney meets the roofline is a common leak point in Severn’s wind-driven rain events. We see failed flashing frequently on the ranch-style and split-level homes that dominate neighborhoods like Harmans Woods and Severn Woods, where roof-pitch geometry creates awkward water-shedding angles. Repair costs $280-$750 depending on whether we’re resealing existing metal or replacing corroded galvanized flashing with copper or stainless. Every flashing job includes inspection of the underlying decking, because catching rot early saves you from a $2,000+ roof repair later.

Trusted Brands We Service in Severn
We stock and install professional-grade materials from Olympia Chimney, Famco, and DuraFlex, among others, because builder-grade substitutes fail faster in Severn’s climate and cost more in callbacks. Our trucks carry refractory panels for HeatShield systems, chase covers sized for common prefab models, and flexible stainless liners for Chimney Liner & Rebuild - Severn jobs. That inventory means most Severn repairs don’t wait on shipping. When a Fort Meade family gets PCS orders and needs a Level-2 inspection turned around fast for closing, or when a homeowner on New Cut Road discovers water stains after a February nor’easter, we have the parts to fix it now, not next week.
Common Chimney Repair Problems We See in Severn Homes
- Deteriorated refractory panels in prefab fireboxes. The factory-built metal fireplaces installed across Severn’s 1970s-1990s subdivisions were designed for 20-25 years of service. At 40-plus years, the panels crack and lose their insulating properties, creating a potential fire hazard. We replace these with OEM or compatible panels rated for the unit.
- Rusted chase covers and deteriorated chimney caps. High humidity from the Chesapeake Bay watershed accelerates corrosion in the galvanized metal components common to Severn’s prefab chimneys. A rusted chase cover channels water directly into the flue, damaging liners and surrounding framing.
- Crown cracks from freeze-thaw cycling. Even masonry chimneys in Severn suffer crown deterioration when water infiltrates minor cracks, expands in freezing temperatures, and widens the damage across winter. We pour solid concrete crowns with proper overhang and drip edges, or apply CrownCoat flexible sealant for smaller cracks.
- Failed flashing at roof penetrations. The combination of age, thermal movement, and Severn’s wind-driven rain exposes flashing gaps that attic inspectors often miss until drywall stains appear. Our camera inspections catch these early.
