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 Woodbury
Chimney cap and crown work in Woodbury typically runs $380-$1,200 depending on whether you need a standard cap install, a custom multi-flue cap, or full crown rebuilding with waterproof coating. Most Woodbury jobs are completed in a single visit after a Level-2 camera inspection, and we dispatch crews to Woodbury from our New York City office with scheduling coordinated for Nassau County routes. Call (631) 776-4075 to book - estimates are free, and a live person answers every call, 24 hours a day.
We’ve worked on enough Woodbury chimneys to know the pattern. The center-hall colonials off Jericho Turnpike, the Tudors tucked behind the Woodbury Country Club, the custom builds in Woodbury Estates - these houses were built when two fireplaces were standard, and the chimney chase was sized for multiple flues. That heritage matters when you’re choosing a cap. A stock single-flue cap from a hardware store won’t cover an abandoned oil-boiler flue, won’t shed water correctly on a wide crown, and won’t address the mortar erosion that Long Island Sound humidity accelerates year after year. Our Chimney Cap & Crown team measures, fabricates, and installs caps and crowns built for the actual chimney on your actual roof - not a generic size that almost fits.

Our Chimney Cap & Crown Services in Woodbury
Cap Installation
New cap installation in Woodbury runs $380-$650 for a standard stainless steel single-flue cap on an accessible chimney. Most of our Woodbury installations aren’t standard, though. The typical Woodbury colonial has a multi-flue chase, and a cap that only covers one flue leaves the other open to rain, squirrels, and downdrafts. We measure the full crown width, account for flue spacing, and install a cap that protects the entire chase top. Materials are professional-grade - we use Famco and Copperfield caps in sizes that actually fit Woodbury’s larger masonry chimneys, not the builder-grade stock that box stores sell by the pallet.
Cap Replacement
Cap replacement in Woodbury costs $420-$780 depending on whether we’re removing a rusted single-flue cap or a failed multi-flue unit that’s been letting water into the chase for seasons. We see this often in the older colonials near Woodbury Road - the original cap was galvanized steel, it rusted through, and the homeowner didn’t notice until water stained the firebox or the damper seized. We remove the old cap, inspect the flue tiles and crown beneath it with a camera, and install a replacement that fits the current condition of the chimney. If the crown is cracked beneath the old cap, we’ll tell you before we proceed. Photos you can see, a plain-English verdict.
Crown Repair
Crown repair in Woodbury typically ranges from $650-$980 for full rebuilding with a bonded waterproof coating. The crown is the concrete slab that tops your masonry chimney, sloped to shed water away from the flues. In Woodbury, coastal humidity from the Long Island Sound corridor saturates the masonry, and winter freeze-thaw cycling cracks that concrete year over year. We see significant spalling and cracking on upper chases that look fine from the ground - damage only visible once you’re at cap level with a ladder and a light. Our crown repair removes the deteriorated concrete, forms and pours a new crown with proper slope and overhang, then applies a CrownCoat-style bonded coating for additional waterproofing. Done right, and we stand behind it.
Crown Coating
For crowns with minor cracking but sound structural integrity, crown coating runs $480-$720 in Woodbury. This is a preventive treatment, not a rebuild - we clean the existing crown, fill hairline cracks, and apply a flexible waterproof membrane that bridges new cracks as the masonry moves through freeze-thaw cycles. It’s a smart investment for Woodbury homes where the crown is showing early wear but hasn’t failed completely. We’ll show you the camera footage and tell you honestly whether coating is sufficient or whether the crown needs rebuilding. Sometimes the answer is coating. Sometimes it’s not. We’ll give you the straight answer either way.
Multi-Flue Cap
Multi-flue caps are our most common Woodbury installation, running $680-$1,050 depending on chase width and material. These caps cover two or more flues with a single hood, mounted to the crown or to exterior brackets that don’t penetrate the flue tiles. For Woodbury’s shared-chase colonials, this is usually the correct solution. A multi-flue cap from DuraFlex or Gelco sheds water off the entire crown surface, blocks animals from all flues simultaneously, and prevents downdraft across the chase. We size them to your exact flue spacing and crown dimensions - no universal sizes that leave gaps.
Custom Cap
Custom caps for Woodbury’s architectural chimneys or non-standard chase configurations run $890-$1,200. We’ve fabricated custom copper caps for historic-style homes near the Woodbury Country Club, oversized hoods for commercial-style fireplaces in newer custom builds, and specialty mounts for chimneys with irregular crown shapes. Custom work requires precise field measurements and shop fabrication, but the result is a cap that fits the way it should and lasts the way it should. We use Copperfield and Famco materials for custom builds - no substitutes.

Trusted Brands We Service in Woodbury
We install professional-grade caps, crowns, and coatings from DuraFlex, HeatShield, Gelco, Famco, and Copperfield - brands that supply the chimney industry, not the retail aisle.

The number on the estimate is the number on the invoice.
Common Chimney Cap & Crown Problems We See in Woodbury Homes
- Single-flue stock caps on multi-flue chimneys. We find this constantly in Woodbury’s 1960s-1990s colonials - a homeowner or a previous contractor installed a hardware-store cap over the active fireplace flue, leaving the abandoned oil-boiler flue completely open. Rain gets in. Animals nest. And that open flue may be cracked and venting into the wall cavity, a Town of Oyster Bay code violation that surfaces during home inspections.
- Mortar-joint erosion from salt-laden coastal air. Woodbury’s exposure to Long Island Sound humidity means masonry absorbs more moisture than inland Nassau County. At cap level, where the chimney is most exposed, mortar joints erode and bricks spall. The damage is hidden from the ground. Only a cap-level inspection with a camera reveals the true condition.
- Freeze-thaw cracked crowns. Saturated masonry goes through repeated freeze-thaw cycles every Woodbury winter. The crown concrete cracks, loses its slope, and pools water directly over the flues. Water tracks down the flue, rusts the damper, stains the firebox, and can damage the liner below.
- Abandoned flues left uncapped after oil-to-gas conversion. When Woodbury homeowners converted from oil to gas heat, the boiler flue was often abandoned in place - no cap, no liner termination, sometimes open at the top. It’s the most common hidden defect we find during Level-2 inspections, and it’s the one that creates the most expensive surprises at closing.

FAQs - Chimney Cap & Crown in Woodbury
Yes, and in Woodbury’s case, infrequent use is often the reason you need it most. Smoldering, low-temperature fires - the kind built for atmosphere in a living room used twice a month - produce stage-2 and stage-3 glazed creosote that doesn’t sweep out easily and burns at lower ignition temperatures than dry, seasoned-wood fires. Meanwhile, the abandoned oil-boiler flue in your shared chase may be cracked and open to the wall cavity, a condition you’d never detect without a Level-2 camera inspection. We inspect chimneys in Woodbury year-round, and we’ll show you exactly what we find. Call (631) 776-4075 for a free estimate.
Your Woodbury home was built when center-hall colonials routinely included a decorative living-room fireplace and an oil-fired boiler served by separate flues within a single masonry chase. When the oil system was replaced with gas, the new boiler often vented through a sidewall or a new flue, leaving the original boiler flue abandoned. That second flue is frequently uncapped, unlined, and cracked - venting into spaces it shouldn’t. Our Level-2 inspection maps both flues with a camera so you know the condition of each. Call (631) 776-4075 to schedule.
A multi-flue cap covers all flues in your chase with a single hood, preventing rain, animals, and downdrafts from entering any opening. For Woodbury homes with an active fireplace flue and an abandoned boiler flue, this is critical - a single-flue cap leaves the second flue exposed. Custom caps address non-standard chase dimensions or architectural requirements. Both are fabricated to your chimney’s actual measurements, not a universal size that almost fits. We install DuraFlex, Gelco, and Copperfield multi-flue and custom caps sized in the field. Call (631) 776-4075 for exact pricing on your chase configuration.
Partially. Woodbury’s coastal humidity from the Long Island Sound corridor saturates masonry more than inland locations, and that moisture expands when it freezes. The crown concrete cracks, the slope fails, and water begins pooling instead of shedding. Salt-laden air also accelerates surface deterioration on the upper chase. We see this pattern repeatedly on Woodbury’s older colonials - damage hidden from the ground until a cap-level inspection reveals spalled brick and eroded mortar. Crown repair or coating stops the water intrusion before it reaches the flue and firebox below. Call (631) 776-4075 for a free inspection and upfront estimate.
Yes, and we consider it essential. On a 1970s center-hall colonial in the Woodbury Estates area, we opened the damper and found two flues in one chase - the living-room fireplace flue with stage-2 glazed creosote and a second flue left open and cracked after the oil boiler was swapped for gas. We installed a custom multi-flue copper cap sized to both clay tiles, rebuilt the spalled chimney crown with a bonded CrownCoat-style coating, and repointed the top mortar joints before the freeze-thaw season. The homeowner had no idea the abandoned liner was venting into the wall cavity until we ran a Level 2 inspection. We document everything with photos, explain it in plain English, and price the full solution upfront. Call (631) 776-4075.
