Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Hempstead Owner’s Guide

Famco chimney cap installation in Hempstead typically runs $225-$425 installed, depending on the cap size, flue dimensions, and whether the old cap has rusted itself to the flue tile. We stock Famco-compatible caps on the truck in the most common Long Island sizes, and most swaps are done in one visit. The way folks usually find out they need this is either a rusted-out cap that’s letting rain pour straight down the flue, or a critter that decided the old cap wasn’t doing its job anymore.

If you’re standing in your driveway looking up at a Famco cap that’s seen better days, here’s what you need to know before you spend a dime.

Which Famco Models This Applies To

The Famco line covers most of what you’ll find on Hempstead rooftops, from single-flue caps to multi-flue and custom chase covers. The key gotcha, and the thing that trips up most DIY attempts, is the inside-mount versus outside-mount sizing. Famco’s stainless steel caps generally mount either outside the flue tile (sliding over the outside edge) or inside it (fitting into the opening), and if you order the wrong one, you’ve got a very shiny paperweight. We measure the actual flue tile outer and inner dimensions on the roof before anything gets ordered or pulled off the truck because there are older Hempstead homes near Hofstra University where the flue is a non-standard size that no online chart accounts for.

Famco caps are solid stainless or galvanized with stainless screens. The mesh sizing matters more than most people think, especially in Nassau County, where nuisance birds and squirrels have opinions about your chimney. We recommend and stock the stainless steel versions, not galvanized, because a Hempstead winter with freeze-thaw cycles on a galvanized cap will have you replacing it in five years instead of fifteen. In our experience, the screen mesh is the first thing to fail on a Famco cap, long before the hood or the mounting legs, because that fine wire takes the brunt of rain, soot acids, and flying embers.

We are an independent chimney service, not a Famco dealer. That’s a good thing for you: it means we’ll tell you when an OEM Famco part is worth the price and when a quality aftermarket equivalent from a manufacturer like Olympia does the same job for less. Often, on older single-flue setups, the Olympia equivalent fits beautifully and saves you $40-$70.

Signs Your Famco Chimney Cap Installation Is Failing

• Rust streaks running down the chimney crown. That orange staining usually means the cap’s base or bolts are corroding. In Hempstead’s salt-tinged air and winter snow, this shows up faster than you’d expect, and what’s rusting on top is often letting water in below.
• Water in the firebox after heavy rain. If the cap’s hood is cracked or the screen is clogged with creosote, rain has a straight shot down the flue. A good cap should shed water even in a nor’easter. If it doesn’t, the cap has failed or was sized wrong from day one.
• You hear birds or scratching above the damper. Chimney swifts and squirrels in Hempstead are persistent. When the cap’s mesh is torn or the cap has shifted off the flue, they move in fast. We’ve pulled more nesting material out of chimneys with “working” caps than I care to count.
• The cap wobbles or sits crooked. Wind from storms off the Atlantic loosens mounting hardware over time. A cap that shifts can scratch the flue tile, get jammed, or tip enough that the screen no longer seals against the flue edge. If it moves when you nudge it gently with a broom handle from the ground, it needs attention.
• Your neighbor’s chimney has a cap and yours doesn’t. Half the time this job starts because someone looked across the street, saw a clean stainless cap, and realized their flue has been open to the sky since the last one blew off. Ask anyone on your street how their chimney’s doing. The answer’s usually more honest than you expect.

Replacement Cost & What’s Included

For Hempstead homeowners, here’s the honest math on Famco cap replacement. The cap itself, depending on size and stainless versus galvanized, runs $95-$210. Labor, which includes getting on the roof safely, removing the old cap, cleaning the flue edge so the new one seats properly, and hauling the old one away, runs $130-$215. So most single-flue Famco replacements land between $225 and $425 all-in.

• Single-flue stainless cap, standard size: $225-$310 installed
• Single-flue stainless cap, oversized or non-standard flue: $310-$390 installed
• Multi-flue or chase-style cap setup: $350-$550+ installed, depends on chase dimensions
• Old cap removal and disposal: included in every install, we don’t leave you a rusty cap in the driveway

Every installed cap we put on carries the 90-Day Done Right Promise in writing. If the cap shifts, whistles, or lets water in within three months, one call to (516) 963-1068 brings Wendell and the crew back at no charge. The number you’re quoted over the phone is the number on the invoice, no surprises at the door. And if you’ve got a written estimate from anyone else saying you need something more expensive, we’ll give you a free second opinion, because half the time the more expensive fix isn’t the right one.

DIY or Call Us?

There’s one real danger with cap replacement: it’s not the cap. It’s the roof. Hempstead roofs are steep on a lot of the older homes, and a chimney chase or flue that’s slick with morning dew or early snow is no place to learn roofing. If you can’t safely stand at the flue with both feet planted and no stretching, this isn’t a DIY job. Every year someone ends up hurt because a cap replacement looked easy from the ground.

That said, you can do a few checks before deciding what to do. From the ground, look for visible rust, a cap that sits crooked, or gaps between the cap and the flue. If you have a masonry chimney and decent binoculars, check whether the screen mesh is intact. Beyond that, this is a two-person job done right, and the second person should be someone who’s been on more Nassau County roofs than he can count. If it doesn’t need doing, I’ll tell you. But if the cap’s failing, waiting only makes the water damage and the critter damage worse. Call (516) 963-1068 and we’ll take a look, no pressure, free estimate.
