Why Hearthstone Chimney Co. Is Jessup’s Preferred Chimney Cap & Crown Company

We’ve been answering calls with a live person for over 42 years, and that hasn’t changed. When you ring (410) 305-7884, day or night, someone picks up. No voicemail. No callback queue.

Our Chimney Cap & Crown team knows Jessup’s housing stock intimately. The 1970s-1990s townhomes and split-levels built during the Route 1 suburban infill boom dominate neighborhoods here, and most were equipped with factory-built zero-clearance fireplaces now at or well past their 20-30 year design lifespan. We’ve replaced rusted multi-flue caps on Jessup townhomes where the original liner was failing simultaneously, and we’ve coated spalling crowns on split-levels near the Columbia line where freeze-thaw cycles had pulverized the mortar joints.

Every inspection ends with photos you can see and a written verdict. Our 90-Day Done Right Promise means if it’s not right, we come back. No paperwork. No arguing. That’s the Keystone Standard we’ve operated under since 1984.

Dispatch and scheduling are coordinated from our Baltimore office, but crews serve Jessup locally and carry the correct permit applications for both Howard and Anne Arundel counties on every truck.

Our Chimney Cap & Crown Services in Jessup

Cap Installation

New cap installation in Jessup runs $280-$520 for standard single-flue models and $450-$780 for multi-flue units covering factory-built chimney systems common in local townhomes. We measure on-site and fabricate to fit, because the prefabricated flue terminals on 1980s zero-clearance fireplaces rarely match modern stock sizes. A proper cap stops rain, keeps animals out, and prevents the downdrafts that send smoke into living rooms during the gusty weather that rolls off the Patapsco River basin.

Cap Replacement

Most cap replacements we do in Jessup involve rusted galvanized units that should have been stainless or copper from the start. Replacement costs $320-$580 depending on flue count and access. We see this constantly in the older townhome clusters near Guilford Road and Dorsey Run Road, where original builder-grade caps have simply dissolved after twenty-five winters of freeze-thaw cycling. We install replacement caps from Olympia Chimney and Gelco, professional-grade products that outlast the originals by decades.

Crown Repair

Crown repair is our most called-upon service in Jessup, and for good reason. The mid-Atlantic freeze-thaw cycle here is brutal on masonry. Winter temperatures oscillate above and below 32°F dozens of times per season, driving repeated water expansion in mortar joints. A typical crown repair runs $480-$720 for partial rebuilds and $650-$850 for full crown reconstruction with proper overhang and drip edge. We use HeatShield and Gelco crown coating systems on suitable substrates, but we’re direct about when the crown is too far gone for coating and needs rebuild. Photos first. Then the recommendation.

Crown Coating

Crown coating with a flexible waterproof membrane costs $380-$580 when the underlying concrete is structurally sound but weather-checked. This is often the right call for Jessup split-levels built in the 1980s where the crown has hairline cracking but no major spalling. We apply Gelco’s professional-grade coating after pressure-washing and priming, and we warranty the workmanship under our 90-Day Done Right Promise. Not every crown qualifies for coating, and we’ll show you exactly why yours does or doesn’t.

Multi-Flue Cap

Multi-flue caps cover the entire chimney top, protecting multiple flues and the crown itself from water intrusion. In Jessup’s townhome developments, where two or three factory-built fireplaces share a common chase, these are essential. Custom-fabricated multi-flue caps run $580-$920 installed. We measure, build, and install in one visit using materials from Copperfield and Olympia Chimney. The alternative is replacing individual rusted caps every few years while water destroys the chase between them.

Custom Cap

Custom caps solve problems that stock sizes can’t touch. Odd flue spacing, oversized chases, or decorative requirements on Jessup’s few custom-built homes near the Patuxent Research Refuge area. Custom fabrication starts at $720 and ranges to $1,200 for complex copper work. We template on-site, fabricate from DuraFlex or Copperfield materials, and install with proper clearance and fastening. A custom cap done right outlasts three stock replacements.

Trusted Brands We Service in Jessup

We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. Our Baltimore office stocks the common cap sizes and crown coating materials for Jessup’s prevalent factory-built fireplace systems, which means faster turnaround and no waiting for special orders on most jobs. When we recommend a specific product, it’s because we’ve installed it on Jessup chimneys, watched it perform through our freeze-thaw winters, and know it holds up.

Common Chimney Cap & Crown Problems We See in Jessup Homes

• Freeze-thaw destruction along Route 1. Winter temperatures in Jessup swing above and below freezing repeatedly, not staying consistently cold. Water seeps into crown mortar, expands, contracts, and expands again. By spring, the crown is cracked and the cap is tilting. We see this pattern on nearly every 1980s split-level we inspect.
• Simultaneous failure of caps, crowns, and liners in factory-built systems. The zero-clearance fireplaces installed in Jessup’s 1970s-1990s townhomes were designed for 20-30 years of service. Many are now forty years old. When we find a rusted cap, we also find a deteriorated flue liner and cracked refractory panels. Fixing only the cap leaves the real breach unaddressed.
• County line permitting confusion delaying repairs. Because the Howard-Anne Arundel county line bisects Jessup neighborhoods rather than following major roads, a crown repair requiring structural permitting might file with Howard County’s Department of Inspections, Licenses and Permits or Anne Arundel County Building Permits. We pull parcel data before scheduling to avoid the two-week delay that comes from submitting to the wrong office.
• Water wicking through cracked crowns into smoke chambers. Once crown mortar fails, water follows the flue tiles down, rusting metal fireboxes, damaging refractory panels, and creating the musty odors homeowners report first. By the time you smell it, the cap has been leaking for seasons.
