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

We’ve been working Maryland chimneys since 1984 - over 42 years - and the Jessup area has been in our rotation long enough that our technicians know which side of the county line they’re on before they unload the ladder. That matters here more than most places. Jessup straddles Howard and Anne Arundel counties, and a cap replacement on a home near Montevideo Road might need Anne Arundel permitting while a crown pour three streets over falls under Howard County. We confirm jurisdiction before we quote, so you’re not waiting weeks for a paperwork shuffle.

Our customers in 20794 tend to be longtime homeowners, not flippers. They call us after the last contractor ghosted them, or after they tried a handyman who didn’t understand why a crown needs a proper drip edge to shed water away from the brick. We document every inspection with photos you can see and a plain-English verdict - no jargon, no scare tactics. The 90-Day Done Right Promise is in writing, with no arguing: if it’s not right, we come back.

Calls are answered by a live person, every hour of every day. Background-checked, uniformed technicians arrive when we say we will, and most cap and crown jobs finish in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.

Our Chimney Cap & Crown Services in Jessup

Cap Installation

New cap installation in Jessup runs $320-$580 for a standard single-flue stainless steel unit, including proper measuring and storm collar sealing. The 1960s ranches near Guilford Road often have flue tiles that have shifted or cracked from decades of freeze-thaw cycling, so we measure twice and fabricate once. We install Gelco and Olympia Chimney caps sized to your exact flue dimensions, not the nearest big-box approximation. A properly fitted cap keeps Patuxent watershed moisture out of your flue, stops downdrafts that blow smoke back into your living room, and blocks the squirrels and starlings that nest in uncapped chimneys every spring.

Cap Replacement

When your existing cap is rusted through, wind-damaged, or was never the right size to begin with, replacement is straightforward but not simple. We remove the old unit without damaging the flue tile, inspect the crown beneath it for hidden deterioration, then install a cap that actually fits. In Jessup’s newer townhome developments, we often find builder-grade galvanized caps that have rusted out in five to seven years. We upgrade these to stainless steel or copper options from Famco that handle Maryland humidity without turning orange. Our Chimney Cap & Crown team carries common sizes on the truck, so most replacements are same-day.

Crown Repair

The concrete crown at the top of your chimney is the only thing keeping rain from saturating the brick below it. In Jessup, where ambient moisture runs high and winter freeze-thaw is reliable, crowns crack, spall, and lose their slope. Crown repair typically costs $380-$620 and involves chipping out deteriorated concrete, re-forming the slope so water runs off (not pools in the center), and pouring new high-strength concrete with embedded reinforcement. For hairline cracks caught early, we use HeatShield CrownSeal, a flexible refractory coating that bridges small gaps and extends the crown’s life by years. We also handle Chimney Liner & Rebuild in Jessup when crown failure has allowed water to damage the flue system below.

Crown Coating

Not every cracked crown needs a tear-out. If the concrete is structurally sound but the surface is weathered and porous, a professional crown coating with HeatShield or similar refractory material runs $280-$450 and adds 10-15 years of protection. We apply it only after pressure-washing and priming the surface, because coating over loose material is a waste of your money and our reputation. This is a popular option for the original Cape Cods near Jessup’s older neighborhoods, where homeowners want to preserve the chimney’s integrity without a major repair bill.

Multi-Flue & Custom Caps

Some Jessup homes, particularly the larger split-levels with multiple fireplaces or a furnace and fireplace sharing a chimney, need multi-flue caps that cover the entire crown. These are fabricated to order from stainless steel or copper, with screened sides for each flue and a proper overhang to shed water. Custom caps start around $680 and can exceed $1,200 for complex configurations. We measure, sketch, and confirm the design with you before anything goes to the fabricator. Done right - and we stand behind it.

Trusted Brands We Service in Jessup

We work exclusively with professional-grade materials: Gelco for standard and multi-flue caps, Olympia Chimney for specialty sizing, Famco for custom fabrication, and HeatShield for crown repair and coating systems. These aren’t builder-grade substitutes you replace twice a decade. We stock common cap sizes and crown repair materials locally, so Jessup homeowners aren’t waiting on freight from out of state. When you need a part we don’t have on the truck, our suppliers are close enough that most orders arrive within 48 hours. A square deal: no surprises on the bill.

Common Chimney Cap & Crown Problems We See in Jessup Homes

• Efflorescence and spalling brick from crown leaks. Jessup’s location in the Patuxent River watershed means high ambient moisture year-round. When a crown cracks or loses its slope, water seeps into the brick below, dissolves salts, and leaves white powdery stains. Left alone, the brick faces pop off entirely.
• Rusted metal chase covers on 1990s-2000s townhomes. The prefab fireplaces in newer Jessup developments came with thin galvanized chase covers that rust through in the local humidity. Homeowners often mistake this for a roof leak until we show them photos from the inspection.
• Deteriorated mortar joints on 1960s-1970s chimneys. The original single-wythe brick chimneys in Jessup’s older neighborhoods were built with mortar that doesn’t hold up to decades of Maryland freeze-thaw. A failing crown accelerates the damage, but the root problem is often the soft mortar itself.
• Improperly sized or missing caps on original construction. We’ve found chimneys in the Route 175 corridor with no cap at all, or with a cap that covers only part of the flue, letting rain and animals enter freely. The fix is simple, but the damage from years of exposure can be extensive.
