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.

AfterFast, Reliable Chimney Cap & Crown Across Silver Spring
A chimney cap and crown repair in Silver Spring typically runs $280-$650 for most homes, with custom multi-flue caps on shared stacks reaching $900-$1,400. Most jobs are completed in a single visit after our Level 2 camera inspection, and we back every repair with our 90-Day Done Right Promise in writing. Call (301) 479-9806 to book a free estimate.
We’ve been working Silver Spring chimneys for over 42 years, and we know the difference between a 1925 Woodside Colonial with original clay flue tiles and a 1950s Four Corners Cape Cod that got converted from coal to gas and then abandoned. Our crews are dispatched from our Washington, DC office and carry the parts and materials to fix most cap and crown problems the same day we diagnose them. Georgia Avenue, Colesville Road, University Boulevard - we’ve worked on chimneys facing all of them, and we understand how Silver Spring’s tight streetcar-suburb lots and attached housing create problems that newer suburbs simply don’t have.
Why Hearthstone Chimney Co. Is Silver Spring’s Preferred Chimney Cap & Crown Company
Silver Spring homeowners call us because we document what we find. Every Level 2 inspection ends with photos you can see and a plain-English verdict - no jargon, no pressure, just the facts about your cap, crown, and flue condition. Our technicians are background-checked, uniformed, and trained to work on the 80-to-100-year-old masonry chimneys that dominate neighborhoods like Woodside, North Woodside, and Woodside Park.
We’ve earned a strong local reputation across Montgomery County, built one job at a time. Our 90-Day Done Right Promise means if it’s not right, we come back - in writing, no arguing, no paperwork to chase down. A live person answers our phones 24 hours a day, 7 days a week, not a voicemail queue. And our no-hassle upfront pricing means the number on the estimate is the number on the invoice.
We know Silver Spring’s housing stock. The freeze-thaw cycles here are harder on masonry than areas just 30 miles south in Virginia, and the shared stacks in attached housing mean one neighbor’s uncapped flue can become your odor problem. That local knowledge changes how we approach every inspection.
Our Chimney Cap & Crown Services in Silver Spring
Cap Installation
New cap installation in Silver Spring runs $280-$450 for a standard single-flue stainless steel cap on most Colonial Revival or Cape Cod chimneys. We fabricate and install caps that fit your flue precisely, with mesh screening that keeps out squirrels, raccoons, and the starlings that nest in open flues across Woodside Park every spring. For chimneys along busy corridors like Georgia Avenue or Colesville Road, a proper cap also blocks wind-driven rain that accelerates liner deterioration.
Cap Replacement
Replacing a rusted, damaged, or improperly fitted cap in Silver Spring typically costs $250-$400. Many of the 1940s-50s houses in Four Corners and Woodside still carry the original cheap galvanized caps installed during mid-century coal-to-gas conversions - they’re usually rusted through after 70 years. We replace them with professional-grade stainless steel or copper caps from Gelco and Olympia Chimney, sized to your actual flue opening, not a hardware-store guess.
Crown Repair
Crown repair on a Silver Spring masonry chimney generally runs $450-$750, depending on how far the spalling has spread. The original crowns on 1920s-1940s chimneys in North Woodside and the Four Corners area were often poured flat or with inadequate slope, so freeze-thaw water pools instead of shedding. We rebuild with proper pitch and expansion joints, then finish with a Gelco crown coating formulated for Mid-Atlantic weather. Done right, and we stand behind it.
Crown Coating
For crowns with early-stage cracking but sound structural integrity, our crown coating service runs $350-$550. This is often the right call for Silver Spring chimneys where the crown is cracked but the brick below hasn’t spalled deeply yet - a common finding in houses that have cycled through rental use with deferred maintenance. We clean the crown surface, fill cracks with compatible mortar, and apply a flexible, waterproof coating that moves with the masonry through freeze-thaw cycles. It’s a square deal: no surprises on the bill, and we’ll tell you honestly when coating is sufficient versus when a full rebuild is the only lasting fix.
Multi-Flue Cap
Multi-flue caps are essential for many Silver Spring chimneys, especially in Woodside’s attached and semi-detached housing where two or more flues share a single masonry stack. A custom multi-flue cap fabricated to cover all openings runs $650-$1,200 depending on size and material. This isn’t a stock hardware-store item - we measure your stack, account for flue spacing and clearances, and fabricate a cap that protects every opening while allowing proper draft. On shared stacks, a multi-flue cap is often the only way to stop cross-contamination between your fireplace and a neighbor’s gas appliance venting into the same chase.
Custom Cap
Custom caps for unusual flue configurations, historic preservation requirements, or aesthetic preferences run $800-$1,400 in Silver Spring. We’ve fabricated custom copper caps for homeowners in Woodside Park who wanted period-appropriate detailing on their 1930s Colonial Revival, and oversized stainless caps for chimneys on Colesville Road with non-standard flue spacing. Every custom cap starts with precise field measurements and ends with a cap that fits like it was made for your chimney - because it was.

Trusted Brands We Service in Silver Spring
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes that fail in five years. For Silver Spring’s older masonry chimneys, this matters. A Gelco crown coating, for example, is formulated to flex through the repeated freeze-thaw cycles that destroy cheaper products. We stock common cap sizes and crown coating materials locally, so most Silver Spring jobs don’t wait on parts. When we find a problem during your inspection, we can usually fix it then - not schedule a return visit two weeks out.
Common Chimney Cap & Crown Problems We See in Silver Spring Homes
- Shared or adjacent flues in Woodside’s attached housing: A neighbor’s uncapped stack lets gas appliance exhaust, creosote odor, and moisture migrate into your fireplace through the shared masonry chase. We see this regularly on semi-detached Colonials where the dividing wall is also the chimney chase. A multi-flue cap and sealed crown edge is the fix.
- Original 1920s-1940s crowns sloped wrong or cracked through: The flat crowns on Silver Spring’s streetcar-suburb chimneys collect water instead of shedding it. Freeze-thaw opens cracks that drop water directly onto clay flue liners, accelerating deterioration. Crown rebuild with proper pitch and a Gelco coating stops the cycle.
- Mid-century coal-to-gas-to-abandoned flues left open: In Four Corners and Woodside Park, chimneys converted to gas in the 1950s and then abandoned when forced-air HVAC arrived now sit uncapped, with collapsed terra cotta liner sections and animal nesting blocking any attempt to relight the fireplace. These require inspection before any cap or crown work - the flue has to be sound before you seal it.
- Moss and organic growth on north-facing chimney faces: Silver Spring’s summer humidity promotes moss growth that retains moisture against masonry year-round, accelerating crown and cap deterioration on shaded sides. We address the underlying moisture issue, not just the visible damage.

What moves the price? Crown size and accessibility are the big ones. A two-story Colonial on a tight Woodside lot with limited ladder access takes longer than a single-story Cape Cod with clear backyard access. The extent of spalling damage matters too - surface cracks are a coating job; crumbled concrete through the crown requires rebuild. Shared stacks need multi-flue caps, which cost more than single-flue but solve a problem no stock cap can touch. We give you the full price before any work starts. Call (301) 479-9806 for a free estimate - we’ll inspect, photograph, and explain exactly what your chimney needs.

FAQs - Chimney Cap & Crown in Silver Spring
In Silver Spring’s Woodside and North Woodside streetcar-suburb blocks, attached and semi-detached houses share or sit inches from a neighbor’s stack, so a single uncapped or crown-cracked flue can cross-contaminate adjacent fireplaces with exhaust, odor, and creosote smell from a neighbor’s appliance. Much of the 1940s-50s housing stock here was converted from coal or wood to gas mid-century and later abandoned when forced-air HVAC arrived, leaving uncapped, open shafts that tie directly into the shared masonry assembly. A Level 2 camera inspection with smoke testing locates the crossover point, and a custom multi-flue cap with sealed crown edges stops the migration. Call (301) 479-9806 to schedule - estimates are free.
Not necessarily. If the spalling is limited to the crown surface and the brick below is sound, crown coating or partial rebuild often suffices - typically $350-$750 versus $2,000+ for full rebuild. We determine this with a camera inspection that shows us how deep the water has penetrated. On 1930s Woodside Park chimneys, we frequently find the crown failed first while the brick beneath is still salvageable. We’ll show you the photos and give you an honest verdict on what can wait and what cannot. Call (301) 479-9806 for an inspection.
Signs include a bricked-up or boarded-over fireplace, a gas line capped off in the firebox, or a chimney with no visible cap that hasn’t drawn in decades. In Silver Spring’s Four Corners and Woodside neighborhoods, this is common - the coal furnace went to gas in the 1950s, then the whole system was abandoned when central air arrived in the 1970s. The danger is an open, uncapped flue full of collapsed liner, animal nesting, or both. We inspect with a camera before any cap or crown work to confirm the flue is sound enough to use or needs relining first. Call (301) 479-9806 - we’ll tell you exactly what you’ve got.
Yes. Silver Spring sits in a genuine freeze-thaw zone - cold enough for repeated hard freezes each winter but with frequent mid-winter warm spells that cycle water in and out of masonry pores. Areas 30 miles south in Virginia see fewer hard freezes and less dramatic temperature swing, so their masonry weathers more slowly. Summer humidity here also promotes moss growth on north-facing chimney faces, which retains moisture against the masonry year-round. The result: Silver Spring chimneys, especially the 80-to-100-year-old stock in Woodside and North Woodside, show accelerated crown deterioration that demands proactive maintenance. Call (301) 479-9806 to assess your crown’s condition.
A stock cap won’t work safely or effectively on a multi-flue stack. Standard caps cover one flue opening; they leave adjacent flues exposed, allow cross-drafting between flues, and often don’t meet clearance requirements for proper venting. In Silver Spring’s attached housing, where two or more flues frequently share a single masonry chase, a custom-fabricated multi-flue cap is the correct solution. We measure your stack, account for flue spacing and appliance types, and fabricate a cap that covers all openings while maintaining proper draft and clearance. Expect $650-$1,200 installed, depending on size and material. Call (301) 479-9806 for exact measurements and pricing.
