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.

AfterTrusted Chimney Cap & Crown for Ewing Homeowners
Chimney cap and crown work in Ewing typically runs $280-$1,850 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. At Hearthstone Chimney Co., we’ve been protecting Ewing homes from water damage, animal intrusion, and structural decay for over 42 years. Our background-checked, uniformed technicians arrive with professional-grade materials from Gelco, Olympia Chimney, and Famco, and every job is backed by our 90-Day Done Right Promise in writing.
Ewing’s freeze-thaw cycles hit chimney crowns harder than almost any other part of your home. The concrete crown sits at the top of your chimney, sloped to shed water. When it cracks, water seeps in, freezes, expands, and turns small problems into rebuilds that cost thousands. A proper cap keeps rain, squirrels, and debris out of your flue. We’ve replaced crowns in homes off Parkway Avenue where the damage started with a hairline crack, and we’ve installed caps in the Mountain View section after raccoons nested in an open flue. The fix is straightforward when you catch it early. Call us at (856) 388-5580 - a live person answers, 24 hours a day.
Russell Haines founded this company in 1984 on a simple idea: do the work right, explain it plainly, and stand behind it. That hasn’t changed. We document every inspection with photos you can see and a plain-English verdict. No surprises on the bill. No arguing if something needs adjustment. Just the job done correctly, the first time.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is a metal cover that sits over your flue, keeping rain, animals, and debris out while letting smoke escape. In Ewing, we install caps on chimneys that have never had one, especially in older neighborhoods like Glendale and Braeburn where original construction skipped this protection. Our technician measures your flue on-site, recommends the right size and material from our stock of Gelco and Olympia Chimney products, and installs it with stainless steel fasteners that won’t rust out in five years. Most installations take under an hour.
Cap Replacement
Caps rust, blow off in storms, or get damaged by falling branches. We replace caps that are beyond repair with new units that match or exceed the original specification. In Ewing, we see a lot of galvanized caps that have rusted through after a decade of Mercer County winters. We upgrade these to stainless steel or copper options from Famco and Copperfield that last 20 years or more. We remove the old cap, inspect the flue tile for hidden damage, and install the replacement with proper clearance and secure mounting.
Crown Repair
The crown is the concrete slab that tops your masonry chimney, sloped to direct water away from the flue. Cracks in the crown are the single most common cause of chimney water damage we see in Ewing. Our crown repair begins with wire brushing and cleaning to expose sound concrete, then we fill cracks with flexible, waterproof sealant rated for freeze-thaw cycling. For crowns with moderate deterioration, we apply a specialized crown coating that bridges small cracks and restores the slope. We don’t just caulk over the problem. We fix what’s failing and tell you honestly when the crown is too far gone for repair.
Crown Coating
Crown coating is a preventive treatment for crowns that are sound but showing early wear. We apply a flexible, elastomeric coating formulated for chimney applications that seals hairline cracks and restores water-shedding ability. This isn’t paint. It’s a specialized product from HeatShield that remains flexible at temperatures from -20°F to 200°F, which matters in Ewing where January nights hit single digits and summer sun bakes the brick. A coating application adds 10-15 years of life to a sound crown at a fraction of replacement cost. We only recommend coating after inspection confirms the underlying concrete is solid.
Multi-Flue Cap
Some Ewing homes, especially the larger colonials in the Scotch Road area and multi-family conversions near the college, have multiple flues sharing one chimney structure. We also install our Chimney Cap & Crown in Princeton for similar homes. A multi-flue cap covers the entire chimney top with one protective structure, eliminating the gaps between individual caps where water and animals enter. We measure the full chimney top, fabricate or order a cap with proper height and mesh screening for all flues, and install it with a secure mounting system that handles wind loads. Multi-flue caps from Olympia Chimney come in stainless steel, copper, and powder-coated finishes that match your roofline.
Custom Cap
Standard caps don’t fit every chimney. We’ve fabricated custom caps for historic Ewing homes with oversize flues, decorative chimney pots, and unusual dimensions. Our custom work uses measurements taken on-site, with materials from Copperfield and Famco cut and formed to your exact specifications. We’ve built copper caps for a 1920s Tudor near the Delaware River that matched original architectural details, and oversized stainless caps for a commercial property on Route 31. Custom work takes longer to fabricate, typically 7-10 days, but the fit and finish are exact.

Brands We Service for Chimney Cap & Crown
We’ve installed and serviced hundreds of Gelco caps across Mercer County. Gelco’s stainless steel line handles our coastal-influenced climate well, and we keep their most common sizes in stock for same-day replacement. Their multi-flue models are particularly reliable for larger Ewing homes with multiple fireplaces.
Olympia Chimney manufactures caps with some of the best mesh screening in the industry, fine enough to stop even small birds and squirrels while maintaining proper draft. We’ve used their products in Ewing’s wooded sections near Baldpate Mountain where animal intrusion is a recurring problem. Famco and Copperfield round out our inventory with specialty sizes and custom options for unusual flue configurations. Whether you have Gelco, Olympia Chimney, Famco, Copperfield, or any other make, we can source parts, match finishes, and install correctly. We don’t substitute builder-grade materials to save a few dollars.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on your ceiling near the chimney. This means water is getting past the crown or cap and running down inside the flue. In Ewing’s older homes, we’ve seen this damage plaster, ruin insulation, and rot roof rafters before the homeowner knew there was a problem. The stain is never the real problem. It’s the symptom of water entry that gets worse every rainstorm.
- Pieces of concrete on the roof or ground near the chimney. Crown concrete spalls when water freezes inside cracks. Those chunks came from the top of your chimney, and every piece that falls off exposes more surface area to water. We’ve rebuilt crowns in Ewing where the homeowner found the first chunk in spring and waited until fall to call. By then, the damage had reached the brick courses below.
- Rust stains running down the chimney face. Rust means metal is corroding, usually the cap or the flue liner top. The stains are unsightly, but the real concern is that a rusting cap is a failing cap. Once it rusts through, water enters freely. We’ve replaced rusted caps in Ewing homes where the underlying flue tile had cracked from thermal shock after years of unprotected exposure.
- Animals or nesting debris in the fireplace. Squirrels, raccoons, and birds enter through uncapped flues or caps with damaged screening. In Ewing’s neighborhoods near wooded areas, this is common in spring and fall. Beyond the mess, animal nests block airflow and create fire hazards. A proper cap with intact mesh prevents this entirely.
- White powder or efflorescence on exterior brick. That white staining is minerals left behind when water evaporates out of brick. It means water is getting into the masonry system, often through a cracked crown or failed cap. Efflorescence in Ewing’s climate typically appears after winter, when freeze-thaw cycling has opened new pathways for water. Left alone, it progresses to spalling brick and mortar joint failure.

Upfront estimate with options. We present a written estimate with clear pricing before any work begins. If the crown can be repaired rather than replaced, we’ll tell you. If the cap is salvageable with new fasteners, we’ll say so. The number on the estimate is the number on the invoice. No surprises.

How Much Does Chimney Cap & Crown Cost in Ewing?
A typical chimney cap replacement in Ewing runs $280-$580, with basic stainless steel caps at the lower end and copper or custom sizes toward the upper range. See our Chimney Cap & Crown cost guide for more detail. Crown repair with crack sealing and coating typically costs $450-$850 depending on accessibility and the extent of deterioration. Full crown removal and rebuild ranges from $1,200-$1,850, and multi-flue cap installation runs $650-$1,100 based on dimensions and material.
Several factors affect where your job falls in these ranges. Chimney height and roof pitch determine how much time the technician spends on a ladder versus working from the roof. The condition of the existing flue tile affects whether we can install a standard cap or need to address underlying damage first. Material choice matters: stainless steel lasts decades and costs less than copper, but some homeowners prefer copper’s appearance on visible rooflines. Accessibility is a real factor in Ewing’s older neighborhoods like Wilburtha and Parkside, where mature trees and tight setbacks can complicate ladder placement.
The best way to avoid overpaying is to get an inspection before the damage spreads. A cracked crown that costs $600 to repair becomes a $1,800 rebuild when water reaches the brick below. We include a free estimate with every inspection, and we’ll tell you plainly when work can safely wait versus when delay costs more money. Nothing is recommended without camera evidence you can see for yourself.
Our $89 Seasonal Tune-Up includes inspection and basic maintenance, and we offer $50 off any repair over $250. Seniors and veterans receive a permanent 5% discount. Call (856) 388-5580 for exact pricing on your chimney.

Frequently Asked Questions - Chimney Cap & Crown in Ewing
The crown is the concrete slab that forms the top of your masonry chimney, sloped to shed water. The cap is a metal cover that sits over the flue opening, keeping rain, animals, and debris out while allowing smoke to escape. Together they form your chimney’s first line of defense against water damage, which is why we inspect both during every chimney service visit.
Most cap replacements and basic crown repairs are completed in two to four hours during a single visit. Full crown rebuilds and custom cap fabrications typically require a return trip and take a full day. We’ll give you a clear timeline in your written estimate before any work begins.
