We’ve been working the chimneys of Silver Spring since 1984, long enough to know which houses on Sligo Avenue have the original 1950s clay flue liners and which neighborhoods off Colesville Road saw their oil furnaces converted to gas in the 1980s, leaving behind abandoned secondary flues that still need caps. Our technicians know the difference between a Woodside Park Cape Cod chimney and a Four Corners split-level stack before they set up the ladder. That’s not guesswork. That’s four decades of looking at the same housing stock, season after season.

Silver Spring sits at that awkward urban-fringe zone where winter temperatures flirt with 32°F for weeks on end, cycling above and below freezing sometimes daily. That freeze-thaw rhythm chews through exposed mortar crowns faster than in colder, more consistently frozen counties. We’ve replaced crowns on Georgia Avenue brick colonials where the spalling was so advanced the homeowner could flake pieces off with a fingernail. The cap was doing its job; the crown beneath it had simply given up after sixty years.

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

Our reputation in Silver Spring was built one flue at a time, starting with the 1980s oil-to-gas conversion boom when half the chimneys in Kemp Mill suddenly needed new caps for abandoned flues. Word traveled through neighborhood associations and church bulletins, the way it still does among homeowners who’ve lived in the same house for thirty years. We’ve earned that trust by showing up when we say, documenting what we find with camera photos the homeowner can see, and pricing the job upfront so the invoice matches the estimate.

We answer our phones with a live person 24 hours a day, 7 days a week. Not a callback queue, not an app, not “leave a message and we’ll get back to you.” When water is dripping down your flue into the firebox at 9 PM on a Saturday, you reach a human being who can dispatch a technician. Most calls from Silver Spring zip codes 20910 and 20911 get same-day or next-day scheduling, and our background-checked, uniformed technicians arrive with the parts to finish the job in one trip.

The 90-Day Done Right Promise governs every cap and crown job we do in Silver Spring. If it’s not right, we come back and make it right, in writing, no arguing. That’s the Keystone Standard, and it’s how we’ve operated since Russell Haines founded this company in 1984. We’re not planning to leave Montgomery County in thirty years, so we treat every repair like we’ll be the ones maintaining it next decade.

Our Chimney Cap & Crown Services in Silver Spring

Cap Installation

New cap installation in Silver Spring runs $280-$420 for standard single-flue stainless steel models, with multi-flue caps for the area’s common dual-flue chimneys starting around $380. Many of the 1940s-1960s brick colonials in Woodside Park and South Four Corners were built with two flues but only ever received one cap, leaving the second flue open to rain and squirrel intrusion. We install Gelco and Olympia Chimney caps sized precisely to your flue dimensions, not the adjustable big-box versions that blow off in the first March windstorm off the Piedmont.

Cap Replacement

Cap replacement is our most common call from Silver Spring, especially after winter storms send the original rusted cap into the neighbor’s azaleas. A typical replacement takes 45 minutes to an hour, costs $320-$480 depending on flue count and access height, and ends with a cap that won’t need thinking about for fifteen years. We see a lot of cheap galvanized caps on Kemp Mill split-levels that were installed by roofers as an afterthought; they last maybe five seasons in our freeze-thaw climate before the seams split.

Crown Repair

Crown repair in Silver Spring addresses the concrete or mortar wash that seals the chimney top between the flue tiles and the brick edge. Proper repair costs $520-$780 and involves removing the deteriorated material, installing expansion joint around the flue, and pouring a new sloped crown with proper overhang and drip edge. The 1950s-era chimneys off Colesville Road were often finished with a thin mortar wash instead of a true concrete crown, which is why we’re replacing so many of them now as they reach seventy-plus years of age.

Crown Coating

For crowns with minor cracking but sound structural integrity, we apply HeatShield CrownCoat, a flexible waterproof coating that bridges hairline cracks and prevents further moisture penetration. Crown coating runs $450-$620 in Silver Spring and adds roughly ten years of protection before full rebuild becomes necessary. It’s a practical middle path for the homeowner who wants to defer major masonry work without letting water destroy the brick beneath. We document the crown condition with level-2 camera inspection photos before and after, so you can see exactly what was protected.

Multi-Flue & Custom Cap

Silver Spring’s older homes frequently need multi-flue caps that cover two or even three flues with a single hood, or custom-fabricated caps for non-standard chimney dimensions. Multi-flue caps start around $520; custom copper or black galvanized steel caps run $680-$1,200 depending on metal gauge and complexity. We measure on-site and order from Famco for custom jobs, with typical turnaround of five to seven business days. The abandoned oil-furnace flues we find in Four Corners and Hillandale are prime candidates for these solutions, especially when the homeowner wants to seal the secondary flue permanently while keeping the fireplace flue functional.

Trusted Brands We Service in Silver Spring

We stock Gelco and Olympia Chimney caps in the sizes that fit Silver Spring’s standard clay flue tiles, which means no waiting two weeks for a part to ship. For crown coating, we use HeatShield products exclusively, the same formulation specified by the Chimney Safety Institute of America. When a custom solution is called for, Famco fabricates to our measurements. We don’t substitute builder-grade materials to shave twenty dollars off a job. The cap that goes on your chimney is the cap we’d put on our own.

Common Chimney Cap & Crown Problems We See in Silver Spring Homes

• Freeze-thaw spalling on crowns. Silver Spring’s winter temperature swings above and below freezing, sometimes daily, force moisture trapped in masonry to expand and contract. The mortar crowns on 1950s Georgia Avenue colonials are particularly vulnerable; we’ve replaced crowns where the surface had degraded to loose gravel.
• Missing caps on abandoned secondary flues. In Kemp Mill and Four Corners split-levels, the original oil-furnace flue was often abandoned in place during 1980s gas conversions. Without a cap, these flues collect rainwater, leaf debris, and animal nesting material, accelerating deterioration of the entire chimney stack while the homeowner remains unaware the flue even exists.
• Rusted-through galvanized caps. The cheap caps installed by roofers on Colesville Road and Sligo Avenue homes in the 1990s and 2000s are reaching end of life. The thin galvanized steel rusts from the inside out, and the first sign of failure is often the cap itself in the shrubbery after a wind gust.
• Improper crown slope causing ponding. Original crowns on Silver Spring’s mid-century chimneys were frequently poured flat or even dished slightly, allowing water to pool instead of shed. Standing water accelerates mortar joint failure and eventually leaks into the attic framing, especially on Cape Cods with shallow-pitch roofs where the chimney penetrates close to the eaves.
