We’ve been working on Elmhurst chimneys since 1984. Our technicians know the difference between a 1920s two-family brick row house on Whitney Avenue and a 1940s semi-detached on 45th Avenue, and we know how the shared party-wall chimneys on these blocks create problems that suburban sweeps never encounter. When you call us, you’re talking to someone who has capped and crowned chimneys on your exact street type dozens of times. We carry DuraFlex and Gelco parts on our trucks, so we’re not ordering materials while water keeps seeping through your cracked crown.

Our Chimney Cap & Crown Services in Elmhurst
Multi-Flue Cap Installation
Elmhurst’s pre-war two- and three-family row houses were built with shared masonry chases containing multiple flues, often under different ownership. A single multi-flue cap covers the entire chase, sealing all flues against rain and wildlife while maintaining proper draft separation. We measure on-site and fabricate custom fits for chase dimensions that vary block by block. On 84th Street in Elmhurst, we capped a multi-flue stack where the original 1930s crown had cracked, sending water down both flues: the active gas furnace flue with its rusted exterior, and the abandoned oil flue with its soaked interior. We installed a custom DuraFlex multi-flue cap with a stainless-steel liner for the active side, then sealed the abandoned flue with a Gelco crown coating to prevent future freeze-thaw spalling. Most multi-flue caps in Elmhurst run $720-$1,400 installed, depending on chase width and flue count.

Crown Repair
The concrete crown at the top of your chimney is the first defense against water. In Elmhurst, Queens coastal winters deliver repeated freeze-thaw cycles that spall exposed brick and erode mortar joints in above-roofline masonry. A cracked crown lets water infiltrate the flue, damage clay tile, and stain interior walls in the attached unit below. We remove deteriorated crown material, pour new concrete to proper slope and overhang specifications, and seal with professional-grade compounds. Crown repair in Elmhurst typically runs $380-$620. If the crown is too far gone, we recommend full rebuild.

Custom Cap Fabrication
Standard box-store caps do not fit Elmhurst’s irregular pre-war chase dimensions. We measure, fabricate, and install custom caps from Copperfield and Gelco materials sized to your exact flue spacing and chase perimeter. Custom caps include proper spark arrestor mesh, minimum 5-inch side height, and welded seams that outlast riveted alternatives. Custom fabrication in Elmhurst runs $580-$920 for single-flue designs, $720-$1,400 for multi-flue. Every custom cap carries the 90-Day Done Right Promise.

Cap Replacement
Old caps rust, blow off in Queens wind, or were never properly secured to begin with. We remove failed caps without damaging flue tile, inspect the crown beneath, and install replacement caps with proper fastening and sealant. Replacement caps in Elmhurst run $280-$480 for standard galvanized, $420-$680 for stainless steel. If your cap blew off after a storm, call (855) 950-3861. We answer live, 24/7.

Crown Coating
For crowns with minor cracking but sound structural integrity, we apply elastomeric crown coating that bridges hairline cracks and sheds water. This is not a substitute for rebuild on severely deteriorated crowns, but it extends service life 5-10 years when applied correctly. Crown coating in Elmhurst runs $320-$480. We only coat after confirming the crown has proper slope and no underlying spall damage.

Common Chimney Cap & Crown Problems We See in Elmhurst Homes
- Party-wall cap deterioration from shared exposure. In Elmhurst’s attached row houses, a shared masonry chase often contains two flues, one for each property. A cap failure on your side causes water damage and draft issues next door, forcing coordination with a neighbor before any crown repair can begin. We’ve mediated these situations dozens of times.
- Abandoned oil flues left uncapped in converted gas chimneys. Homeowners cap only the active gas flue but leave adjacent abandoned oil flues exposed in the same chase, creating a cold-air downdraft that accelerates creosote buildup in the active flue. In Elmhurst’s row-house blocks, technicians routinely scope a chimney and find that the adjacent property’s abandoned oil-to-gas conversion left an uncapped flue sharing the same masonry stack.
- Freeze-thaw spalling on aging crowns. Queens sits in a coastal mid-Atlantic climate with significant freeze-thaw cycling each winter, which steadily spalls exposed brick crowns and erodes mortar joints in the above-roofline sections of Elmhurst’s aging masonry chimneys. This deterioration goes unnoticed until water infiltration cracks the flue tile or causes interior wall staining in the attached units below.
- Missing spark arrestors accelerating moisture entry. Old clay-tile flues in unlined gas-converted chimneys crack from condensation. The original cap’s missing or undersized spark arrestor accelerates moisture entry, leading to spalled crowns and damaged flue liners that require more extensive repair.

FAQs - Chimney Cap & Crown in Elmhurst
Yes, if the masonry chase is a true party wall with flues serving both properties, both owners should agree to the scope of work before we begin. We have handled this coordination many times in Elmhurst’s row-house blocks and can provide written scope descriptions for both parties. Call (855) 950-3861 and we’ll explain the process for your specific chase configuration.
Yes, an abandoned flue left open inside a shared chase pulls cold outside air across your active gas flue, accelerating moisture condensation and creosote accumulation even if you schedule annual cleanings. We seal abandoned flues with proper termination caps or crown-level sealing, depending on condition. This is one of the most common corrections we make in Elmhurst’s converted two-family houses.
Queens winters cycle above and below freezing dozens of times per season, forcing water trapped in masonry pores to expand and contract. This spalls brick crowns, widens mortar joints, and eventually cracks flue tile. A properly fitted cap with adequate overhang and a sound crown slope is your primary defense. We inspect for this specific deterioration pattern on every Elmhurst call.
Yes, this is our standard practice for Elmhurst’s 1920s-1950s housing stock. We measure flue spacing, chase dimensions, and roofline clearance on-site, then fabricate from Copperfield or Gelco materials to fit. No two pre-war chases in Elmhurst are identical, so custom fitting is not an upgrade here. It is the baseline requirement for proper protection.
Yes, crown damage is rarely visible from the ground until it has progressed to interior water damage. Our Level-2 camera inspection includes roof-level crown and cap photography with a plain-English verdict. In Elmhurst’s dense housing, we often find crown cracks hidden by cap overhang that have already begun leaking into party-wall cavities. The inspection cost is $89 as a standalone service, free with any repair estimate.
