Famco Crown Repair Nationwide

Famco Crown Repair: The Hempstead Owner’s Guide

If your Famco chimney cap or crown assembly has cracked, rusted through, or started pulling away from the flue, we can match and install the correct Famco replacement, typically for $380 to $720 including parts and labor in Hempstead. We carry Famco crown and cap components on our trucks, and if your specific size is in stock, we can often complete the swap the same day we arrive. Most Hempstead homeowners discover the problem one of two ways: water staining on the ceiling near the chimney, or a visible crack in the crown when they’re in the yard or up on a ladder during gutter cleaning.

The crown is the concrete or metal cap that sits on top of the chimney chase, sealing the gap between the flue pipe and the chase walls. Famco makes a specific line of galvanized and stainless crown assemblies sized to fit their flue extensions and chase covers. When it fails, water gets in, and water is what turns a $500 repair into a $4,000 rebuild. We’d rather catch it at $500.

Which Famco Models This Applies To

Famco manufactures crown and cap assemblies for their sheet metal chimney systems, and the part you need depends on the flue diameter and chase opening, not just the brand name stamped on the old piece. We regularly match replacements for Famco’s residential chase cover and crown kits that fit 6-inch through 10-inch flues, including their multi-flue configurations common in older split-level and colonial homes throughout Hempstead and the Village.

Here’s the compatibility gotcha we see constantly: Famco crowns are not universal across their own line. A crown built for a single-wall 8-inch flue will not seat correctly on a double-wall insulated 8-inch flue. The inner ring diameter differs by roughly a half inch, which is enough to leave a gap that drips water for years before you notice the damage. You’ll find the model number stamped on the underside of the old crown or on the chase cover lip. If it’s rusted to the point of being unreadable, we take a roof measurement and confirm the spec against Famco’s current fabrication chart before ordering. No guessing. A wrong guess means a second trip and a second charge from most companies; we check measurements twice before we ever order a part.

There are aftermarket equivalents for many Famco crown assemblies, and some are fine. But in Hempstead’s salt-air corridor, the difference between 26-gauge and 30-gauge galvanized is the difference between a crown that lasts nine years and one that starts pitting at year four. We typically recommend the genuine Famco component or a heavier-gauge aftermarket spec we’ve verified. We stock both and will tell you the exact material thickness on the written quote. We also work with DuraFlex, HeatShield, and Gelco components on the flue side, so if the crown failure has caused liner damage below it, we can address that in the same job.

Signs Your Famco Crown Repair Is Failing

• Water staining on the ceiling around the chimney chase. This means water has been getting past the crown for a while. The stain you see is the first visible sign; the rot behind the drywall started months earlier.
• Rust streaks running down the chase or brick. The galvanized coating on the Famco crown has worn through. Once bare steel is exposed to Hempstead’s wet winters, the crown is in structural decline.
• Visible cracks in the crown’s concrete or mortar apron. Freeze-thaw cycles on Long Island open hairline cracks into full channels within two or three winters. A cracked crown admits water every time it rains.
• The chase cover lifts or rattles in wind. The fasteners have either corroded or pulled loose. This is also a symptom that the original install used the wrong hardware for pressure-treated lumber, a mistake we correct on every job.
• Debris or nesting material inside the flue when you shine a light down. A failing crown often widens the gap around the flue pipe, which lets squirrels and birds in. By the time you see the nest, the crown’s seal has been compromised for at least a season.

Replacement Cost & What’s Included

A Famco crown replacement in Hempstead typically runs $380 to $720 installed, depending on the flue size, whether you need a single or multi-flue assembly, and whether the existing chase cover can be reused. Here’s how that breaks down:

• Standard single-flue Famco crown assembly: $140 to $240 for the part
• Multi-flue or oversized crown: $210 to $340 for the part
• Labor including roof access, old crown removal, and install: $220 to $360
• Sealant and hardware: included. We use high-temp silicone rated for chimney chase applications, not hardware store caulk.

Every crown repair gets a written price before we start, and every repair carries our 365-Day Done Right Promise: if the crown leaks or fails within a year, we return at no charge. No deductible, no argument. The number you approve is the number on the invoice. The flue tells the truth. You just have to know how to read it, and that starts with writing down what we’re going to do and what it costs.

DIY or Call Us?

You can safely inspect a Famco crown from the ground with binoculars or from a ladder if you’re comfortable and the roof is walkable. If you see rust blooms, cracked concrete, or a gap between the flue and the crown, that’s your call to action. What we don’t recommend is a homeowner pulling a crown and reinstalling one: you’re working on a roof, often on a wet or pitched surface, handling sheet metal with sharp edges, and sealing a system that vents carbon monoxide and smoke. A bad seal there isn’t a cosmetic problem. It’s a carbon monoxide pathway into the house if the draft reverses under the right conditions.

A failed crown is also usually the tip of the problem, not the whole problem. The water that got in has often traveled down the flue and hurt the liner, which is why we inspect the liner with a camera on any crown repair. You don’t need to know how to fix it. You need to know exactly what’s broken. That’s what we’re for. Call (516) 559-6922 and we’ll get on the roof, take the measurements, and put a written number in your hand.
