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 working on Severn chimneys for over 42 years, and we know what the Chesapeake Bay does to them. The salt air off the bay corrodes galvanized caps in half the time you’d see inland. The freeze-thaw cycles crack mortar that was already aging when Reagan was president. And the military rental turnover near Fort Meade means maintenance records vanish like morning fog. We document everything with photos, explain what we’re seeing in plain English, and fix only what needs fixing.
Why Hearthstone Chimney Co. Is Severn’s Preferred Chimney Repair Company
Severn homeowners call us because we show up when we say we will, we photograph every defect before we recommend a repair, and we back every job with the 90-Day Done Right Promise in writing. No arguing. No paperwork shuffle. If it’s not right, we come back.
Our Chimney Repair team knows the local housing stock. Most Severn homes went up during the Fort Meade expansion boom of the 1960s through 1980s, brick colonials and split-levels with original terra cotta flue liners now pushing 50 or 60 years. We’ve replaced crowns on Reece Road, tuckpointed chases off Telegraph Road, and rebuilt fireboxes in neighborhoods where the same family has owned since the Cold War and others where the tenant turns over every two years.

Our Chimney Repair Services in Severn
Chimney Waterproofing
Water is the enemy of every Severn chimney, and it attacks from two directions. Summer humidity in the Chesapeake Bay watershed lets moss and moisture infiltrate dormant flues. Winter freeze-thaw cycles force water inside porous brick, then expand it into cracks. We apply professional-grade waterproofing agents that allow the masonry to breathe while repelling liquid water, critical for Severn’s coastal climate. Most waterproofing jobs on a standard Severn colonial run $650-$1,100 and carry our 90-Day Done Right Promise.

Flashing Repair
Rusted flashing at the roofline is one of the most common calls we get from Severn homes, especially older colonials with original galvanized steel. Bay salt accelerates corrosion where the chimney meets the roof, and once water wicks into the attic, you’re looking at sheathing damage and interior stains. We replace failed flashing with copper or stainless components from Copperfield and Famco, materials that withstand Severn’s salt air for decades. Typical flashing repair in Severn costs $400-$850.

Tuckpointing & Mortar Repointing
The mortar joints in Severn’s 1960s-1980s brick chimneys have endured 40 to 60 years of thermal cycling, and many are crumbling. Tuckpointing removes deteriorated mortar to a proper depth and repacks with color-matched masonry cement that bonds to the original brick. On a recent job off Reece Road near Fort Meade, our crew found the original terra cotta flue liner cracked from decades of thermal cycling, a galvanized chimney cap eaten through by bay air, and five years of glazed creosote in the firebox. We rebuilt the Chimney Cap & Crown - Severn, swapped the cap to stainless, tuckpointed the exterior chase, and pulled a Level 2 inspection camera through the flue before handing it back to the landlord. Repointing on a Severn chimney typically runs $800-$2,200 depending on access and square footage.

Spalling Brick Repair
When moisture penetrates brick and freezes, the face of the brick pops off. Severn’s freeze-thaw cycle makes this worse than in milder climates, and spalling left unchecked weakens the entire chimney structure. We remove damaged brick, address the moisture source, and install matching replacement units. Severn spalling repairs generally fall between $500 and $1,800.

Trusted Brands We Service in Severn
We stock professional-grade materials from Gelco, Olympia Chimney, and Copperfield on our Severn-bound trucks, so most repairs don’t wait on parts orders. Gelco stainless caps resist the salt corrosion that destroys galvanized units in three to five years near the bay. Olympia Chimney liners and components handle the thermal stress of Severn’s older fireplaces. Copperfield flashing and accessories install clean and last. No builder-grade substitutes. The right material for coastal exposure, not the cheapest thing that’ll get through the season.
Common Chimney Repair Problems We See in Severn Homes
- Galvanized caps rusted through in 3-5 years. Severn’s bay air destroys galvanized steel; we replace with stainless as standard, not an upgrade. A rusted cap lets rain pour directly onto the crown and down the flue, accelerating every other failure mode.
- Freeze-thaw cycles crack exterior mortar joints. Severn winters deliver enough freeze-thaw to aggressively attack aging mortar, while rusted flashing at the roofline lets water wick into the attic. The combination often means both problems need addressing together.
- Original terra cotta flue liners develop hairline cracks. In Severn’s 1960s-80s colonials, decades of thermal cycling fracture the liner, which then absorbs moisture and causes spalling brick and weak draft. A Level 2 camera inspection finds this before it becomes a rebuild.
- The “Fort Meade assumption gap” leaves chimneys unswept for years. Military and contractor families renting near Fort Meade assume the landlord serviced the chimney; landlords assume the outgoing tenant didn’t burn wood heavily. We regularly find 5-10 years of glazed creosote where both parties believed someone else had handled it.

FAQs - Chimney Repair in Severn
Every Severn chimney should be inspected annually, and we recommend Level 2 camera inspection every two to three years due to salt corrosion and humidity exposure. The bay air accelerates metal degradation, and freeze-thaw cycles stress masonry beyond what inland climates demand. Annual inspection catches cap and flashing corrosion before water enters the system. Call (443) 464-2560 to schedule; estimates are free.
Yes. Galvanized steel caps in Severn typically rust through in 3-5 years, compared to 8-12 years in drier inland towns like Odenton or Hanover. The salt-laden air off the Chesapeake Bay accelerates corrosion dramatically. We specify stainless steel caps from Gelco or Copperfield as our default for Severn installations, not as an upsell. The replacement cost difference pays for itself in longevity.
Hairline cracks in a terra cotta liner can sometimes be addressed with HeatShield cerfractory resurfacing if the damage is limited and the liner structure is sound. More extensive cracking, shifting, or spalling tile requires a Chimney Liner & Rebuild - Severn for safety. In Severn’s 1960s-80s housing stock, we find full replacement is more common than repair because decades of thermal cycling have compromised the terra cotta. We pull a camera, show you the photos, and give you a straight recommendation. Call (443) 464-2560 for a camera inspection.
The military rental turnover near Fort Meade creates a genuine maintenance gap. Incoming tenants assume the landlord had the chimney swept; landlords assume light use by the previous tenant meant no buildup. We regularly find 5-10 years of glazed, stage-three creosote in Severn rentals where both parties believed someone else handled it. This is a fire hazard and a carbon monoxide risk. If you’re renting or own a rental near Fort Meade, verify the last Chimney Cleaning & Sweep - Severn date in writing or call us for a camera inspection.
Water enters micro-cracks in the crown and mortar joints, expands when it freezes, and widens those cracks with every cycle. Severn’s position in the Chesapeake Bay watershed means adequate moisture is always present, and winter temperatures regularly cross the freezing threshold. A compromised crown lets water into the flue system; deteriorated mortar weakens the chimney structure. We rebuild crowns with proper slope and overhang, and we repack mortar with formulations designed for coastal freeze-thaw exposure. Crown rebuilding in Severn typically runs $900-$2,500.
