Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Bellevue Owner’s Guide

Famco chimney cap installation in Bellevue typically runs $340-$620 depending on flue size, roof pitch, and whether the existing cap was improperly mounted. We stock Famco-compatible caps in common sizes for Bellevue’s prevalent 6″ and 8″ flue diameters, and most installations are completed in under two hours with the written price agreed before we start. Most Bellevue homeowners discover their cap has failed during the first heavy rain of autumn, when water streaks down the firebox or they notice rust stains on the exterior masonry that weren’t there in July.

Which Famco Models This Applies To

Famco manufactures several cap series, and the right match depends on your flue type, not just the brand name on the box. We regularly install Famco caps on standard single-flue galvanized models (the SC series), stainless multi-flue caps (the MC series), and the specialty wind-directional caps that Bellevue hillside homes in Somerset and Lakemont often need for draft control.

To identify your replacement, check the stamped model number on the existing cap’s skirt edge, or measure the flue tile’s outside dimension to the nearest eighth-inch. A common mismatch we see in Bellevue: homeowners order a cap by chimney top measurement rather than flue tile measurement, ending up with a 13″ x 13″ cap on a 12″ x 12″ flue that gaps and leaks within a season. We source Famco caps through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco equivalents, and we’ll show you both the OEM Famco option and the compatible aftermarket choice that meets the same spec. The camera doesn’t guess. Neither do I.

Signs Your Famco Chimney Cap Installation Is Failing

• Rust streaks down the chimney face. Galvanized caps in Bellevue’s marine climate typically show surface rust at year 4-6, but streaking means the cap skirt has separated from the mesh or the sealant bed has failed. Water is now running behind the cap rather than off it.
• Mesh sides detached or sagging. The spark arrestor mesh on Famco caps is spot-welded at the corners; if one weld cracks, the mesh pulls away and creates an entry point for squirrels and nesting birds. We find active nests in about one in eight failed caps we remove in Bellevue.
• Cap shifted or tilted after wind. A properly installed Famco cap uses stainless steel screws into the flue tile crown, not just gravity and friction. If yours has rotated even slightly, the mounting holes have wallowed out or the crown itself has degraded underneath.
• Water in the firebox after rain. This means the cap is either missing entirely, the lid has blown off, or the internal damper below the cap is corroded open. In Bellevue’s wet season, this accelerates flue liner deterioration from the top down.
• Draft smoke spillage on startup. Famco wind-directional caps can seize if the pivot bearing corrodes, which happens faster near the salt air influence in Newport Shores and along Lake Washington. The cap stays pointed wrong and fights your draft instead of helping it.

Replacement Cost & What’s Included

Every Famco chimney cap installation in Bellevue includes the cap, stainless mounting hardware, high-temp sealant at the flue tile interface, and a post-install photo record showing the seated fit from multiple angles. The price you sign before we start is the price you pay. Work is backed by our 365-Day Done Right Promise, and the photo documentation is archived under Haven Standard Clause 4, same as every job we’ve done since 2009.

DIY or Call Us?

Checking whether your Famco cap is loose is safe enough from the ground with binoculars. Look for tilt, missing mesh, or gaps between cap skirt and flue tile. If you have a single-story home with a walkable roof and you’re comfortable with a ladder, confirming the model stamp is reasonable.

Installation is where DIY goes wrong. You’re working at height, often on a wet composite or cedar shake roof that Bellevue’s moss and morning dew make treacherous. More critically, over-tightening mounting screws into older flue tile cracks the crown; under-tightening and the cap departs in the next windstorm. Corrine Halstead and our crew carry the right tapcons, crown sealant, and torque sense from years of Bellevue rooflines, including the steeper pitches in Clyde Hill and Medina where a fall is not a sprain. Call (425) 696-0387 and we’ll give you a written price before anyone sets a ladder.
