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 Elwood
Chimney cap and crown repair in Elwood typically runs $280-$890 depending on whether you’re sealing a cracked crown or replacing a rusted cap on a two-flue stack, and most jobs are completed in a single visit with the work photographed before and after. If you live in one of Elwood’s post-war Cape Cods or ranches off Elwood Road or Jericho Turnpike, your chimney was likely built in the 1950s or 1960s with a single brick stack serving two flues - one for the original oil furnace, one for the fireplace - and that configuration creates specific problems our Chimney Cap & Crown team sees weekly. Call (631) 776-4075 and a live person will answer, 24 hours a day. We’ll schedule a Level-2 camera inspection, show you exactly what your crown and caps look like from the top down, and give you upfront pricing before any work begins.

Our Chimney Cap & Crown Services in Elwood
Cap Installation
New cap installation in Elwood typically costs $340-$620 for a standard single-flue stainless or galvanized unit, or $580-$890 for a multi-flue cap covering both flues on those common two-flue chimneys. Many Elwood homes still have original caps - or no cap at all - from the 1960s construction boom, and an unprotected flue in this area collects debris, animal nesting material, and direct rainfall that accelerates the mortar erosion already sped up by salt-laden air from Long Island Sound. We size the cap to your flue configuration, not a generic guess, and we verify fit with a camera check from the top.
Cap Replacement
Cap replacement is our most frequent chimney cap call in Elwood. The original galvanized caps on 1950s-1970s chimneys rust through after decades of nor’easter exposure, and homeowners often don’t notice until water stains appear on the ceiling near the chimney breast or until a sweep pulls a squirrel nest from the flue. Replacement runs $280-$540 for standard single-flue models, with multi-flue caps running higher. We stock Gelco and Famco caps in common Elwood sizes, so most replacements happen same-visit once we confirm measurements.
Crown Repair
Crown repair addresses the concrete slab that seals the chimney top between the flue tiles and the brick edge. In Elwood, wind-driven rain from Long Island Sound hits these crowns harder than inland Suffolk County locations, and the freeze-thaw cycle opens cracks that let water straight into the chimney structure. Repair costs $420-$780 depending on crown size and whether we need to rebuild the entire pour or can seal existing cracks with proper crown sealant. We never recommend crown work without camera documentation showing water intrusion paths - you’ll see the cracks yourself before we quote.
Crown Coating
Crown coating is preventive maintenance for Elwood chimneys with crowns showing early hairline cracking but still structurally sound - a common find on 60-to-70-year-old chimneys that have survived intact but won’t last another decade unprotected. The service runs $280-$450 and buys significant time against full rebuild. We use professional-grade flexible crown sealants designed for Long Island’s temperature swings, not the hardware-store brush-on products that crack within two seasons. On a ranch off Elwood Road, our tech found the oil flue abandoned with no liner insert while the gas furnace vented into an oversized clay tile flue - camera footage showed first-degree creosote and cracked tile joints. We installed a DuraFlex stainless liner sized to the new appliance and sealed the chimney crown, and the homeowner watched every step on the monitor before we recommended a thing.

Common Chimney Cap & Crown Problems We See in Elwood Homes
- Nor’easter damage to aging crowns. Long Island’s sustained wind-driven rain cracks and spalls already-aging chimney crowns, letting water into the flue and accelerating mortar erosion. Elwood’s proximity to Long Island Sound makes this worse than purely inland locations. We find this on nearly every 1960s-era chimney we inspect.
- Missing caps on abandoned oil flues. After gas conversions, the old oil flue sits open - no cap, no liner - collecting rain, leaves, and animal nests that block the flue and damage remaining clay tiles. This is a consistent finding in Elwood’s split-levels and ranches.
- Acidic condensation cracking clay liners. Gas appliances vent into oversized flues never engineered for them, producing acidic flue-gas condensation that cracks clay tile liners from the inside. Routine cleanings uncover the debris; only camera inspection confirms the liner damage.
- Undersized or wrong-fit caps from prior contractors. We’ve removed caps that were clearly bought off a hardware shelf and forced onto flues they don’t fit, leaving gaps that channel water directly onto the crown. Proper sizing matters, especially on multi-flue Elwood chimneys with uneven flue heights.

FAQs - Chimney Cap & Crown in Elwood
From the ground, a cap can look intact while the mesh sides are rusted through or the mounting brackets have loosened, creating gaps that let in rain and animals. In Elwood, salt-laden air from Long Island Sound accelerates rust on galvanized caps faster than inland locations, so a cap that looks okay at street level often fails up close. We verify with a camera inspection - you’ll see what we see before we recommend replacement. Call (631) 776-4075 for a free estimate.
If the old oil flue is abandoned and capped, it does not need a liner for an inactive appliance - but the flue serving your active gas appliance absolutely needs a properly sized stainless liner per Town of Huntington code. Elwood’s post-war two-flue chimneys were built for oil burners with larger flue dimensions; gas appliances require smaller, properly sized flues to prevent acidic condensation that destroys clay tile. We find unlined gas flues on nearly every older Elwood home we inspect, and we document the condition with camera footage before recommending any liner work.
NFPA 211 recommends annual inspection for all chimneys, and in Elwood’s climate with salt air, freeze-thaw cycles, and aging 60-to-70-year-old construction, that annual check is not conservative - it’s necessary. Clay tile liners crack progressively, and crown deterioration accelerates once started. Catching it early with a Level-2 camera inspection means crown coating instead of crown rebuild, cap replacement instead of water-damaged masonry. Call (631) 776-4075 to schedule.
Crown coating is a preventive sealant applied to a crown with minor hairline cracking but solid structural integrity - it costs $280-$450 and extends service life significantly. Crown repair addresses deeper cracking, spalling, or structural breakdown where water is already penetrating the chimney structure, running $420-$780 for partial rebuild or $780-$1,400 for full replacement. We determine which you need through camera inspection, not a ladder glance, and we show you the footage before quoting either.
A multi-flue cap can improve draft by standardizing airflow across both flues and preventing wind-induced downdrafts, but it will not fix an improperly sized flue or a damaged liner - the real draft killers in Elwood’s converted gas chimneys. If your two-flue chimney has one abandoned oil flue and one active gas flue venting into an oversized clay tile liner, the multi-flue cap helps protect both openings but the liner sizing is the underlying issue. We assess the full system with camera inspection and recommend the cap and any liner work together, with photos you can see and a plain-English verdict.
