Famco Chimney Cap & Crown in Boston: What to Know First

Independent Famco chimney cap and crown work in Boston typically runs $340-$1,150 depending on whether we’re replacing a single-flue cap, rebuilding a spalled crown, or fitting a custom multi-flue setup. Most jobs are completed in one visit, with a written price in your hand before any tool comes off the truck. If you own a Famco cap or crown on a Boston roofline, this page covers how they fail, what we charge, and what to expect when we fix it. Call (857) 567-8887 and we’ll schedule a camera-scan inspection first, so the quote is based on what’s actually up there, not what we guess.

How Famco Products Fail - and How We Fix Them

Famco builds solid, no-nonsense caps and crowns. But Boston weather has a way of finding the weak points in any sheet metal or masonry. Here’s what we see on Famco units across the city.

• Famco SC-series single-flue caps: mesh clogging from cottonwood and maple seed. The SC line uses a standard galvanized or stainless mesh screen. In neighborhoods like Jamaica Plain and Roslindale, spring cottonwood packs that mesh solid within two seasons. Symptom: your fireplace starts smoking back into the room even though the flue is open. Fix: we remove the cap, replace the mesh with a wider-spacing screen where code allows, and document it with photos before and after.
• Famco MC multi-flue caps: mounting bracket corrosion at the chase lip. The MC series mounts with galvanized brackets that sit directly on the chase top. In Boston’s freeze-thaw cycles, water wicks under the bracket, rusts it, and stresses the cap’s frame. We regularly replace those brackets with stainless equivalents and apply a bead of urethane sealant rated for New England temperature swings.
• Famco CC-series cement crowns: efflorescence and surface spalling. Cement crowns always crack eventually. The CC series is no exception, especially on older triple-deckers with unlined masonry chimneys. White powdery staining (efflorescence) means water is moving through the crown’s pores. Symptom: crumbling crown edges we can see from the roof without even leaning a ladder. Fix: if the crown is structurally sound, we use a polymer-modified crown coating. If it’s beyond coating, we form and pour a new one with a proper drip edge and expansion joint.
• Famco stainless single-flue caps (SSC line): baffle plate loosening in coastal winds. Homes near Dorchester Bay and the Harbor Islands catch wind that vibrates the baffle plates on some SSC caps until the screws back out. Homeowners report a metallic rattling noise that comes and goes with gusts. Fix: we re-seat the baffle with high-temp thread locker and add a second set of standoff screws if the frame allows. If it’s the older design with slip-fit corners, replacement usually costs less than the labor to re-engineer the cap.
• Famco damper-top caps: rust-through at the lid hinge. The damper-top line saves heat but exposes a hinge and cable assembly to flue gases and rain. After 8-12 New England winters, we find hinge pins seized or the lid rusted thin. Fix depends on the cable run condition. If the cable is intact, we swap the lid assembly and keep your existing top plate. If the cable has frayed, a straightforward damper-top replacement is faster and cheaper than repairing the old mechanism.

Our Famco Chimney Cap & Crown Process

Every Famco job in Boston follows the same sequence, whether it’s a simple cap swap or a full crown rebuild.

1. 1
   Call and tell us what you’re seeing. You reach a live person at (857) 567-8887. We schedule a two-hour window and text you when the tech is on the way.
2. 2
   Camera-scan inspection first. Clause 4 of the Haven Standard requires a documented photo record on every visit. We run the camera down the flue and climb up to look at the cap and crown. You see the photos.
3. 3
   Written scope and written price before work starts. We name the Famco model if the label’s still legible, describe the failure, and hand you a firm number. No “we’ll see once we start.”
4. 4
   Parts decision: OEM where it matters, quality aftermarket where it’s smarter. Famco OEM caps are well-built, but some older brackets and screens have better aftermarket versions. We explain the trade-off in plain terms and let you decide.
5. 5
   The repair or replacement. Cap swaps are done same-day. Crown rebuilds are staged over two visits if we’re pouring new concrete that needs cure time before the cap goes back on.
6. 6
   Verification and warranty. We run the camera again or take roof-level photos, email you the documented record, and hand you a written warranty. If it’s not done right, the 365-Day Done Right Promise means we come back and make it right.

Why Boston Homeowners Call Level Two Chimney Boston for Famco Work

We’ve inspected and cleaned over 38,000 chimneys since 2009, and a meaningful share of those had a Famco cap or crown on top. Corrine Halstead set the standard early: camera down the flue, written price before work starts, and a documented record when it’s done. That practice became Clause 4 of the Haven Standard, and we’ve never done a job without it. Our techs are background-checked and uniformed, they know which Famco parts hold up in Boston’s freeze-thaw cycles, and if your chimney needs more than cap work, we stock and install DuraFlex liners, HeatShield cerfractory, and Gelco products as well. One call covers the whole chimney. And if you have a written estimate from another company, bring it. We’ll give you a free second opinion.
