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.

Chimney cap and crown repair in Redland typically runs $280-$890 depending on whether you need a standard cap replacement, custom multi-flue cap, or full crown coating with masonry repair. Most Redland jobs are completed in a single visit, and we’ll give you the full price before we start. Call (301) 719-5236 to schedule - a live person answers 24 hours a day.
We’ve been working on Redland chimneys for over 42 years, and we know this area’s housing stock intimately. The 1970s and 1980s colonials and split-levels off Redland Road and around Redland Station weren’t built like the older masonry homes closer to DC. They’re factory-built prefabricated systems on tight lots, often retrofitted multiple times, with flues that terminate close enough to share problems with the neighbor’s stack. That matters when you’re choosing a cap or fixing a crown. Our Chimney Cap & Crown team dispatches from our Washington, DC office, and crews are in Redland regularly - we know the permit history, the common chase configurations, and the cross-contamination issues that price-cutting outfits miss entirely.
Why Hearthstone Chimney Co. Is Redland’s Preferred Chimney Cap & Crown Company
Redland homeowners call us because we document what we find. Every inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. Our Level-2 camera inspection shows you exactly why your crown is spalling or your chase cover is rusted through, and we explain what can wait versus what can’t.
We’re not a one-truck operator who might answer the phone next week, and we’re not a chain sending salespeople with commission quotas. Hearthstone has served Montgomery County communities since 1984. Our technicians are background-checked, uniformed, and trained to spot the layered installation histories common in Redland homes - wood inserts added during the 1980s energy crisis, gas-log conversions through the 1990s, chase covers that have been baking in the DC metro humidity for 40-plus years.
The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we make it right - in writing, no arguing, no paperwork chase. That’s been our standard for four decades, and it’s why Redland homeowners who’ve been burned by contractors before trust us with their chimneys.

Our Chimney Cap & Crown Services in Redland
Cap Installation
New cap installation in Redland runs $280-$450 for standard single-flue galvanized or stainless caps on factory-built chimneys. We size for your exact flue termination - critical here because prefab flues in Redland’s 1970s-80s subdivisions often terminate at non-standard heights or angles due to original construction shortcuts or later retrofit work. A cap that doesn’t fit precisely leaves gaps for water, animals, and debris. We use Olympia Chimney and Famco caps in dimensions that match your system, not whatever’s in the van that day.

Cap Replacement
Cap replacement in Redland typically costs $320-$520 when the existing cap is damaged, improperly sized, or missing entirely. We see this constantly on homes near Redland Station and along Shady Grove Road - original caps rusted off, or chase covers that were never properly flashed. We remove the failed component, inspect the crown beneath for hidden water damage, and install a replacement that actually fits. No surprises on the bill: the estimate number is the invoice number.

Crown Repair
Crown repair in Redland ranges from $450 for minor crack sealing to $890 for full rebuilds on masonry crowns that have suffered serious spalling. The DC metro’s freeze-thaw cycles hit hard here - water penetrates hairline cracks, expands overnight when temperatures drop below 32, and blows the crown apart by spring. Redland’s humid summers compound the problem with efflorescence and mold growth that accelerates deterioration. We use professional-grade crown coatings from HeatShield and Copperfield that flex with temperature swings rather than cracking again next winter.

Crown Coating
Crown coating is our most requested preventive service in Redland - $380-$650 depending on crown condition and square footage. For factory-built chimneys with concrete crowns or masonry wash caps, we apply a flexible, waterproof membrane that seals existing hairline cracks and prevents new water intrusion. This is especially valuable on Redland’s 40-50 year old prefab systems where the original crown was never designed to last this long. One coating, properly applied, can add a decade of service life. We photograph the before condition, apply the coating, and document the result for your records.

Multi-Flue Cap
Multi-flue caps in Redland cost $520-$780 installed, and they’re essential for homes with adjacent flue terminations on shared chase structures. This is not a niche product here - it’s a standard solution for a standard Redland problem. When neighboring flues terminate within a few feet on the same roofline, a missing or failed cap on one house can pull exhaust, creosote odor, and moisture into the adjacent stack through shared chase cavities. We size and fabricate multi-flue caps that cover both terminations with proper clearance, using stainless steel from Olympia Chimney that won’t rust through like the original galvanized chase covers.

Custom Cap
Custom caps for unusual flue configurations or historic aesthetic requirements run $650-$1,200 in Redland. Some of the larger colonials off Redland Road have non-standard chimney profiles, or homeowners want copper or powder-coated finishes to match roofing. We measure on-site, fabricate to spec, and install with proper flashing integration. No template jobs - each custom cap is built for that specific termination, that specific roof pitch, that specific exposure to wind and weather.

Trusted Brands We Service in Redland
We don’t use builder-grade substitutes. Hearthstone stocks professional-grade caps, crowns, and coating materials from Olympia Chimney, Famco, and Copperfield - brands that hold up to Redland’s specific climate stressors. That means faster turnaround for Redland customers because we’re not ordering parts that sit in a warehouse for two weeks. When we find a rusted-through chase cover or spalled crown during your inspection, we can often complete the replacement same visit. Our warehouse carries common stainless cap sizes for factory-built flues, HeatShield crown coating in both standard and cold-weather formulations, and Copperfield flashing kits sized for the 6/12 and 8/12 roof pitches common in Redland’s split-level subdivisions. Done right - and we stand behind it.
Common Chimney Cap & Crown Problems We See in Redland Homes
- Rusted-through factory chase covers. The original galvanized steel chase covers on Redland’s 1970s-80s prefabs weren’t designed to last 40-50 years. When they fail, water pools directly on the crown below, accelerating spalling and freeze-thaw damage that a simple cap replacement won’t fix.
- Cross-contamination from adjacent flues. Because Redland’s tight lots cluster prefab terminations close together, a neighbor’s missing cap or failed chase cover can vent creosote and gas-log exhaust into your shared chase cavity. You smell it in your living room. The fix is a properly sized multi-flue cap with sealed separation between flues.
- Multi-generation liner mismatches exposed during cap work. That wood insert added in 1982, then converted to gas logs in 1998? The liner configuration frequently doesn’t match Montgomery County permit records or current NFPA 211 requirements. Pulling a failed cap often reveals an unlined or undersized flue that must be addressed before any new cap is safe to install.
- Spalled crowns from freeze-thaw cycling. The DC metro’s winter temperature swings - often 20-30 degrees in a single day - destroy concrete crowns with hairline cracks that grow into structural failures. Redland’s humidity makes it worse; water doesn’t just freeze, it sits and soaks.

FAQs - Chimney Cap & Crown in Redland
Yes. On Redland’s tight lots, shared chase cavities let exhaust and creosote odor migrate from one flue to another when a cap or chase cover fails. We install multi-flue caps with proper separation to stop this cross-contamination. Call (301) 719-5236 and we’ll assess whether your termination is vulnerable.
Gas log retrofits in prefab fireboxes often leave liner configurations that don’t match Montgomery County permits or NFPA 211. Removing a failed cap can expose an unlined or undersized flue that would be unsafe to recap without correction. Our Level-2 inspection documents the actual configuration before we quote any cap or crown work. Call (301) 719-5236 to schedule.
Redland’s factory-built prefabs use thinner-gauge galvanized chase covers and minimal concrete crowns that weren’t designed for 40-50 years of DC metro freeze-thaw cycling and summer humidity. Older masonry suburbs have thicker crowns and more durable construction. The materials simply age out faster here, which is why we recommend pre-heating-season inspections for Redland homes. Call (301) 719-5236 to book yours.
That depends on what the camera inspection reveals. If your prefab firebox is past the 30-year manufacturer design life - common in Redland’s 1970s-80s housing stock - and shows refractory panel deterioration or rusted firebox components, we’ll recommend a full assessment. If the unit is structurally sound and only the cap and crown have failed, coating and replacement is sufficient. We give you photos and a plain-English verdict either way, with no pressure to proceed beyond what’s necessary. Call (301) 719-5236 for a free evaluation.
For most Redland homes with active heating appliances, yes - one Level-2 inspection and cleaning annually, scheduled before burning season, catches cap and crown deterioration before it becomes water damage or cross-contamination. Homes with multi-generation retrofits (wood insert, then gas logs) or known shared-chase issues may benefit from a mid-season visual check of exterior caps and chase covers, which we can often do from the ground or a short ladder set. We’ll tell you honestly whether your specific situation needs more frequent attention. Call (301) 719-5236 to set your schedule.
