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 Van Nest
A chimney cap and crown replacement in Van Nest typically runs $380-$740 for a standard single-flue cap with a poured or coated crown, and most jobs are finished in one visit. Multi-flue caps on the shared stacks common to Van Nest’s attached brick row houses run higher, usually $650-$1,100, because the crown base has to be rebuilt to seal both flues. If you’ve got water staining near the chimney, a rusted cap, or spalling brick on the upper course, call (980) 580-8641 and we’ll put a written price in your hand before any work starts.
We know Van Nest’s housing stock. Most of the chimneys we work on here sit on 1920s-1940s attached brick row houses and two-families, often with a flue shared between two dwellings. That changes how a cap and crown job has to be done, and we’ve been doing it that way across the Bronx for years.
Why Emberly Chimney Cleaners Is Van Nest’s Preferred Chimney Cap & Crown Company
We earned our reputation in Van Nest by treating every chimney as a shared system, not a single-family flue. When our technicians arrive, they check what’s venting into the stack, whether the adjacent unit has converted to gas, and whether the original clay liner is still intact. That’s the difference between a cap that lasts and one that rusts out in three seasons because the neighbor’s oversized flue is pushing condensation into the cavity.
Every job is quoted in writing before we start. That’s not a policy we tacked on. It’s Clause 1 of the Haven Standard, the operating rules we’ve worked under since 2009. You get a written scope, a written price, and a written warranty before our crew touches a ladder. If a competitor has given you a written estimate, bring it in and we’ll give you a free second opinion on it. We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and every single one included a documented photo record, per Clause 4 of the Haven Standard.
Van Nest customers call us because we answer the phone. Live person, 24 hours a day. Our technicians are background-checked and uniformed, and you’ll know who’s coming before they arrive. Corrine Halstead runs our operations, and she holds every job in Van Nest to the same standard: if it’s not done right, we make it right. That’s the 365-Day Done Right Promise, and it’s stamped on every job we do.
Our Chimney Cap & Crown Services in Van Nest
Our Chimney Cap & Crown team handles the full range of cap and crown work in Van Nest. Here’s what we cover most often in this neighborhood.
Cap Installation
A new stainless or copper cap on a single-flue Van Nest chimney ranges from $380-$520 installed, including the screen and fastening. We stock caps sized for the 8×8 and 8×12 clay flues common in this housing stock, and we’ll cut a custom cap when the flue opening is non-standard. Every cap we install carries a written warranty.
Cap Replacement
If your existing cap is rusted through, missing its screen, or blowing off in Bronx winter winds, replacement runs $420-$680 depending on flue size and material. On Van Nest’s attached row houses, we often replace caps that were never sized correctly in the first place. An undersized cap on an oversized converted flue fails early, which is exactly what the neighborhood gas conversions have created.
Crown Repair
Chimney crowns in Van Nest take a beating from freeze-thaw cycling. Temperatures cross 32°F dozens of times each winter, and an 80-year-old mortar crown with hairline cracks lets water in every time. Crown repair runs $300-$550 for patching and resurfacing. Full crown rebuilds, which happen more often on shared stacks with two flues, run $600-$900. We use Gelco crown coat products for a weatherproof seal.
Crown Coating
A Gelco crown coat over a sound but weathered crown runs $250-$420. This is the right call when the crown shows surface erosion but no structural cracking. It buys years of protection and, on Van Nest’s shared chimney stacks, it seals the cap base so cross-draft moisture from an adjacent flue doesn’t work its way under the cap and into the masonry.
Multi-Flue Cap
When two flues share one crown, as they do on most Van Nest two-families, a multi-flue cap is the correct fix. These run $650-$1,100 installed because the crown base must be leveled and sealed before the cap goes on. We install copper and stainless multi-flue caps with stainless screens and wind-resistant fastening, sized to the actual flue openings we measure on-site.

We source our caps and crown materials from manufacturers we trust: DuraFlex for stainless liners and connectors, Gelco for crown coat and sealant products, and Copperfield for copper caps and custom fabrication. We keep common Van Nest sizes in local stock so most cap and crown jobs don’t wait on a parts order. When a custom cap is called for on an odd-sized shared flue, we fabricate it through our network and have it on-site within a week.
Common Chimney Cap & Crown Problems We See in Van Nest Homes
- Shared-stack cross-drafting. When one side of a two-family Van Nest row house has a capped, dormant flue and the other side has a gas boiler venting into an oversized clay liner, the active flue pulls air and moisture through the neighbor’s abandoned side. That rusts caps from underneath and soaks the crown cavity.
- Freeze-thaw crown erosion. The Bronx’s hard winters put water into micro-cracks, freeze it, and widen the gap. After 80-100 winters, crowns on Van Nest chimneys are typically eroded to the point where water reaches the clay liner and starts spalling the brick below the roofline.
- Improperly sized caps on converted flues. A home that converted from oil to gas but still vents into the original 8×8 clay flue produces far more condensation than the flue was designed for. That condensation eats cap screens and rusts cap bases in two to three seasons.
- Animal entry through uncapped or under-screened flues. Van Nest’s dense street grid gives pigeons and squirrels easy roof access. An uncapped flue on an attached row house is an open door to a nest, a blocked flue, and a carbon monoxide hazard.

FAQs - Chimney Cap & Crown in Van Nest
You can cap only your side, but it rarely solves the problem. On Van Nest’s attached row houses, the two flues typically share one masonry crown and one cap base. Capping your side while leaving the neighbor’s flue uncapped or improperly terminated still lets water and downdraft air into the shared crown cavity, which corrodes your new cap from underneath. The right fix is a multi-flue cap across both flues, with a rebuilt crown sealing the shared base. Call (980) 580-8641 and we’ll camera-scan both flues and show you exactly what’s happening in the shared cavity.
Look for hairline cracks, crumbling mortar at the flue line, or water staining on the ceiling near the chimney. If you can see daylight through a crack or the crown has a concave dip that pools water, it needs repair before the first hard freeze. Van Nest’s freeze-thaw cycle will turn a small crown crack into a big masonry repair by March. A quick visual inspection and a photo report will tell you what’s urgent. Call (980) 580-8641 and we’ll document what we find, with photos, before recommending any work.
Gas boilers produce far more water vapor than the oil or coal boilers those 8×8 clay flues were built for, and because the flue is oversized, that vapor condenses inside the flue instead of escaping. The condensate is mildly acidic and gets pulled up and deposited on your cap screen and base, rusting them out in a couple of seasons. The correct fix is an NYC-code-compliant stainless steel liner sized for a gas appliance, and then a properly fitted cap on that liner. Ask for a camera scan first; we’ll show you the condensation pattern before we recommend anything. Emberly Chimney Cleaners has been documenting this exact issue since 2009, and we stock the DuraFlex stainless liners to fix it.
Partially. A properly sealed multi-flue cap will stop cross-draft at the top of the stack, but if the flue liners are cracked or the shared mortar joints have failed, exhaust can migrate between flues through the masonry wall anywhere along its height. That’s a code and carbon monoxide issue, not just a cap issue. We camera-scan the entire flue before capping a shared stack in Van Nest, because a cap alone does not fix a gas leak between adjacent flues. If the scan shows liner failure, we’ll quote the relining in writing. Every job gets a documented photo record. Call (980) 580-8641 to schedule the scan.
Every year, before heating season. On attached row houses with shared stacks, we recommend an annual visual inspection of the cap, crown, and upper flue, and a camera-scan Level 2 inspection every two to three years or whenever a unit’s heating appliance changes. The freeze-thaw damage, shared-stack moisture, and gas conversion issues we see in Van Nest make annual checks genuinely necessary, not just the standard “once a year” advice. The inspection takes under an hour, and you get photos and a written report. Call (980) 580-8641 to book it.
