Why Hearthstone Chimney Co. Is Severn’s Preferred Chimney Cap & Crown Company
We’ve worked on chimneys along Reece Road and in the neighborhoods around Fort Meade for over four decades. That longevity matters in a community where military families rotate through on PCS orders and the next homeowner inherits whatever the previous owner neglected.
Our reviews from Severn customers consistently mention the same things: we show up when we say we will, we explain what we found in plain English, and we leave photos they can actually understand. No jargon, no scare tactics.
Response time to Severn averages under 90 minutes during business hours because our dispatch routes us straight down MD-175 or I-97 depending on traffic. We’re familiar with the HOA requirements in communities like Severn Meadows and the older covenants near the historic district, so we don’t install a cap that your association will make you tear off next month.
Most importantly, we understand that Severn’s housing stock - those 1970s-1980s ranchers and split-levels built for the Fort Meade workforce boom - came with factory-built metal fireplaces that need different care than traditional masonry. A crown on a prefab chase cover fails differently than a mortar crown on brick, and we know both.
Our Chimney Cap & Crown Services in Severn
Cap Installation
New cap installation in Severn runs $320-$550 for a standard single-flue galvanized or stainless steel unit, with copper caps starting around $780. We measure on-site because prefab chase covers in neighborhoods like Harmans Woods often require custom sizing that doesn’t match catalog specs. Our Chimney Cap & Crown team carries Olympia Chimney and Famco inventory on the truck, so we’re not ordering parts and making you wait two weeks.
Cap Replacement
Replacing a rusted or wind-damaged cap in Severn typically costs $280-$480. The humid Chesapeake Bay air here accelerates corrosion, especially on the galvanized steel caps that were standard issue in the 1980s. We see this constantly in the older subdivisions off MD-174, where original caps have simply dissolved after 40 years of salt-laden summer humidity. We remove the old unit, inspect the flue tile for hidden damage, and install a stainless steel or copper replacement that won’t need attention again in your lifetime.
Crown Repair
Crown repair in Severn ranges from $450 for crack sealing and resurfacing to $1,200-$1,800 for a full pour of new concrete with proper overhang and drip edge. The freeze-thaw cycles here are brutal: roughly 20 inches of annual snow melts, seeps into hairline cracks, and expands overnight when temperatures drop. We’ve rebuilt crowns on colonials near Severn Run and ranchers closer to Odenton that had deteriorated so badly water was pooling in the firebox below. Every crown repair includes our 90-Day Done Right Promise in writing.
Crown Coating
Crown coating with a flexible waterproof membrane costs $380-$620 in Severn and adds 10-15 years of life to a structurally sound crown that has minor cracking or surface spalling. This isn’t a substitute for a failed crown, but for the homeowner in Severn who caught the problem early - maybe during a Chimney Cleaning & Sweep in Severn - it’s a square deal that prevents a full rebuild later. We use professional-grade materials, not the hardware-store brush-on products that peel within two seasons.

Trusted Brands We Service in Severn
We stock DuraFlex, Famco, and Copperfield caps and crown materials on our Severn-area trucks because we’ve learned that factory-built fireplaces in this market need specific fitments you can’t improvise. When a chase cover on a 1985 prefab unit in the 21144 ZIP code has rusted through, we don’t fabricate something close. We install the component that was engineered for that system, documented with photos you can see and a plain-English verdict on what we found. No builder-grade substitutes, no surprises on the bill.
Common Chimney Cap & Crown Problems We See in Severn Homes
- Spalling concrete crowns on 1970s-1980s masonry. The original crowns in Severn’s first development waves were often poured with weak mortar mixes and no reinforcement. Forty years of Chesapeake freeze-thaw cycles have left them crumbling. We rebuild with proper Portland cement mix, reinforcement mesh, and a 2-inch overhang that sheds water away from the brick.
- Rusted chase covers on prefab fireplaces. Factory-built units in Severn’s dominant housing stock came with galvanized chase covers that simply weren’t designed to last 40+ years. When we lift a deteriorated cover, we often find the firebox below has been taking rainwater for years.
- Missing or improperly sized caps. Severn’s wind exposure off the Patapsco River valley can lift lightweight caps, and we’ve found more than one home where a previous owner installed a cap that doesn’t actually cover the flue tile, leaving a gap for rain and animals.
- Crown separation from flue tile. The clay flue liner expands and contracts at a different rate than the concrete crown. In Severn’s climate, that thermal cycling eventually opens a gap that water exploits. We seal this properly or recommend a full rebuild depending on severity.
