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.
Famco Crown Repair: The Flushing Owner’s Guide
We stock and install Famco-compatible crown repair assemblies in Flushing, with most jobs running $340-$680 installed depending on crown size and flue count. If we have your Famco model on file, we can often match the part and complete the work in a single visit. Most Flushing homeowners discover the crown has failed after spotting fresh water stains on the chimney breast or finding sandy debris in the firebox that wasn’t there last season.
Which Famco Models This Applies To
Famco crowns are found most often on their 8-inch and 10-inch round top-sealing damper assemblies, particularly the TD series and the older SD-line units still common in the 1960s and 1970s brick stock of northeastern Queens. The crown itself is the cast or fabricated metal cap that seals the flue terminal, and it is not interchangeable across series without verifying the flange width and bolt pattern.
To identify your part, look for the Famco stamp on the damper frame, usually visible from the firebox with a flashlight. The TD series carries a three-digit model suffix (TD-800, TD-1000) that corresponds to flue diameter in millimeters. The SD line used a simpler size marking. If the stamp is corroded, which we see regularly on Flushing chimneys facing the salt air drift from Little Neck Bay, measure the flange width across the bolt holes and the overall crown diameter. A 1/4-inch mismatch here means a leak in six months.
We carry OEM Famco crowns where available, and we also stock fabricated equivalents from Olympia Chimney and Gelco that match the TD-series bolt pattern exactly. The aftermarket units use 304 stainless rather than Famco’s original galvanized, which in Flushing’s freeze-thaw cycling typically adds four to six years of service life. We are an independent service provider with no affiliation to Famco.
Signs Your Famco Crown Repair Is Failing
- Water staining on interior chimney walls. A cracked or separated crown lets rain run straight down the flue tile joints. In Flushing’s older homes, especially the attached brick near Kissena Park, that water often travels laterally through party-wall brick before it shows inside, so the stain may appear on a wall nowhere near the fireplace.
- Sandy grit or rust flakes in the firebox. This is the crown’s galvanized steel breaking down from the top. Once you see it below, the crown has been compromised for at least one heating season, sometimes two.
- Damper operation stiffens or seizes. The Famco TD-series damper cable runs through the crown housing. When the crown warps from rust expansion, it pinches the cable guide. We see this most on south-facing chimneys in Flushing where afternoon sun accelerates the thermal cycling.
- Visible crown separation or lifting at the flue rim. From the ground this looks like a dark gap between the crown and the top flue tile. Up close, the crown may have shifted an inch or more off-center, which breaks the seal entirely.
- Unexplained cold drafts when the fireplace is not in use. The Famco crown’s inner seal is a metal-to-metal joint with a fiber gasket. Once that gasket hardens and shrinks, which it does after roughly 12-15 years in Queens humidity, the chimney becomes an open vent.
Replacement Cost & What’s Included
In Flushing, Famco crown replacement typically runs $340-$680 installed for a single-flue system, and $580-$920 for a two-flue chimney with a larger fabricated crown. The range reflects three things: whether we can reuse the existing damper frame, whether the flue tile top needs refractory patching, and whether the crown is a standard TD-series size or requires custom fabrication.
Every job includes removal and disposal of the failed crown, installation of the new assembly with high-temp sealant rated to 2,000°F, and a Level-2 camera inspection of the flue below so you see what we see. We document the condition with photos and a plain-English verdict. The work is covered by our 90-Day Done Right Promise in writing, no arguing. We also apply our standing $50 off any repair over $250, and seniors and veterans receive a permanent 5% discount.
DIY or Call Us?
A homeowner can safely check the crown from the ground with binoculars for obvious separation, and can confirm the Famco model stamp from inside the firebox with a flashlight. Do not climb the roof to inspect it yourself. The crown sits at the highest point of the chimney, often on a 6/12 or steeper pitch common in Flushing’s older housing stock, and the metal edges are sharp enough to cut through work gloves once corroded.
Replacement requires working at height with proper fall protection, plus the torque to break free rust-sealed bolts without damaging the damper frame beneath. We’ve been called to fix DIY attempts where the flange got warped from an impact driver used at the wrong angle, turning a $400 crown job into an $1,100 damper assembly replacement. A clean flue isn’t a luxury. It’s just the job done right. Call us at (516) 206-6672 and we’ll give you a straight answer on what you’re actually dealing with.
FAQs
In Queens conditions, an original galvanized Famco crown typically lasts 12-18 years, while a 304 stainless replacement extends that to 18-24 years. The salt air exposure from Long Island Sound, combined with freeze-thaw cycling through January and February, accelerates corrosion at the flange seam. Call (516) 206-6672 for an exact quote on replacement - estimates are free.
Surface rust can be treated and sealed if the crown is still structurally sound and the flange bolt pattern is undistorted. If the crown has lifted, warped, or thinned through at any point, replacement is the only lasting fix - patching holds for a season at best. We will show you the camera footage and tell you honestly which category you’re in.
Most Famco crown replacements take 90 minutes to two hours from ladder set to final photo. We complete most jobs in a single visit, and our technicians arrive background-checked and uniformed with the part already on the truck if you’ve given us the model information ahead of time.
We stock TD-series crowns in 8-inch and 10-inch sizes, and we carry Olympia Chimney and Gelco equivalents that match the Famco bolt pattern for same-day installation. For older SD-line units or custom sizes, we fabricate to spec with a 48-hour turnaround. A live person answers our phone 24 hours a day, 7 days a week to check availability for your specific model.
