We’ve been working on Midwood’s chimneys for decades. The neighborhood’s concentration of 1920s-1940s brick Colonials and Tudors, many sitting within a mile or two of Jamaica Bay, presents a specific problem: salt-laden coastal air that eats galvanised metal years faster than it fails inland. Our crews know the difference between a chimney that needs a quick crown coating on East 16th Street and one that needs full cap replacement with stainless hardware near Avenue J. Dispatch and scheduling run from our New York City office, but our technicians live and work across Brooklyn and arrive with the parts to finish most jobs the same day.

Why Hearthstone Chimney Co. Is Midwood’s Preferred Chimney Cap & Crown Company

Our reputation in Midwood was built one brick chimney at a time. Homeowners here talk to each other on these quiet residential blocks, and we’ve found that a job done right on East 17th Street leads to a call from East 18th the following week. We’re not a chain sending whoever’s available; our background-checked, uniformed technicians know the local housing stock and its particular failure modes.

Response time to Midwood is typically same-week during peak season, with emergency calls triaged by the live person who answers our phones 24 hours a day, 7 days a week. No voicemail, no callback queue. When water’s pouring through a rusted cap during a January nor’easter, that matters.

What sets us apart here is documentation. Every inspection ends with photos you can see and a plain-English verdict. If your crown is cracked, we’ll show you exactly where. If your cap needs replacement, we’ll explain why stainless makes sense for Midwood’s coastal exposure versus galvanised that’ll rust through again in three seasons. Then we put the 90-Day Done Right Promise in writing. If it’s not right, we make it right. No arguing, no paperwork chase.

Our Chimney Cap & Crown Services in Midwood

Custom Cap Installation

Midwood’s older chimneys weren’t built to standard modern dimensions. Many 1930s Colonials on blocks like East 16th and East 17th have oversized flue openings or multiple flues clustered irregularly. Off-the-shelf caps won’t seal properly. We measure on-site and order custom caps from Gelco and Famco in stainless steel, cut to fit your chimney exactly. A proper custom cap in Midwood runs $450-$780 installed, including hardware and sealant. The alternative - a loose-fitting stock cap - lets salt air and rain infiltrate, accelerating the crown damage you’re trying to prevent.

Cap Replacement

Replacement is our most common Midwood cap call. Galvanised caps installed even five or ten years ago show rusted seams, corner holes, and screen deterioration from Jamaica Bay salt exposure. On East 17th Street we pulled a galvanised multi-flue cap off a 1930s Colonial whose corners had rusted through and were dumping rust flakes down a bare 12×12 flue venting a modern gas boiler. We replaced it with a stainless Famco multi-flue cap, poured a crowned Gelco crown coating over the salt-eaten mortar, and relined the flue with a DuraFlex stainless liner sized for the boiler. Cap replacement alone in Midwood typically runs $320-$650. When paired with crown work or relining, we bundle for a flat price agreed before we start.

Crown Repair

Original 1920s-1940s crowns in Midwood were thin, flat mortar pours, often little more than a sloped wash. Decades of freeze-thaw cycling - Brooklyn winters drop below freezing dozens of times, and salt moisture accelerates the damage - leave them spiderwebbed with cracks. Water wicks through, freezes, expands, and separates the crown from the brick below. Crown repair involves removing loose material, applying a bonding agent, and pouring new crowned concrete with proper overhang and drip edge. Midwood crown repair runs $380-$720 depending on accessibility and how far the damage has spread into the brick courses beneath.

Crown Coating

For crowns with minor cracking but sound structure, crown coating is the cost-effective option. We use HeatShield and Gelco elastomeric coatings formulated for masonry expansion and contraction. In Midwood’s climate, where temperature swings of 40 degrees in a single winter day aren’t unusual, flexibility matters. A coating job runs $280-$450 and adds 10-15 years of protection if the underlying crown was basically sound. We won’t sell you a coating if the crown is too far gone - we’ll show you the photo and explain why repair or rebuild makes more sense. Photos you can see, a plain-English verdict.

Trusted Brands We Service in Midwood

We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes that fail early in coastal conditions. For Midwood’s salt-air environment, we specify stainless over galvanised as standard practice, and we keep common cap sizes and crown coating supplies on our trucks to avoid return visits. Most jobs are completed in a single visit. The brands we use are the same ones specified by chimney professionals nationwide because they hold up to real conditions, not showroom displays.

Common Chimney Cap & Crown Problems We See in Midwood Homes

• Galvanised caps rust through at the seams within a few seasons. Atlantic and Jamaica Bay salt moisture attacks the galvanised coating at cut edges and seams first. Once rust starts, it accelerates. Water pours straight down the flue, often onto an unlined 12×12 interior that was never meant to handle liquid exposure.
• Original 1920s-1940s crowns crack under freeze-thaw cycling. Thin, flat mortar pours with no reinforcement can’t handle Brooklyn’s winter temperature swings. Salt water wicks into hairline cracks, freezes overnight, and widens them. The damage spreads to mortar joints and flashing before most homeowners notice staining on interior walls.
• Crown and flashing failures hide bigger problems. The oversized, unrelined flue serving a modern gas boiler may have been “working” for years with poor draft. Once the cap fails and rain starts cooling the flue further, draft gets worse. Carbon monoxide risk increases. Many Midwood homeowners don’t know their chimney violates NYC DOB liner-sizing requirements until we show them the camera image.
• Multi-flue caps on converted coal chimneys fit poorly. Original chimneys built for coal had large exterior dimensions and multiple flues. Modern gas appliances need smaller, properly lined flues. Stock multi-flue caps sit loose on these old footprints, letting wind-driven salt rain penetrate from the sides.
