Famco Chimney Cap Installation Nationwide

Famco Chimney Cap Installation: The Evanston Owner’s Guide

Famco chimney cap installation in Evanston typically runs $280-$520 for most single-flue residential caps, including removal of the failed unit, flue measurement, and proper mounting with corrosion-resistant fasteners rated for Lake Michigan’s salt-air exposure. We stock Famco-compatible caps in common sizes and can usually schedule within 48 hours. Most Evanston homeowners discover the problem after a windstorm off the lake loosens the cap, or when water staining appears on the firebox ceiling after spring rains saturate a rusted-through mesh.

Which Famco Models This Applies To

Famco manufactures several cap series, and the right match depends on your flue type and existing hardware. The Wind Directional Cap (stainless or galvanized) rotates with airflow to prevent downdrafts, common in Evanston’s lakefront blocks where wind hits masonry stacks from multiple angles. The Standard Single-Flue Cap with 3/4-inch mesh suits most 8×8 to 13×13 clay flue tiles found in pre-1960 Evanston homes. The Multi-Flue Cap covers the entire chimney crown and is spec’d by width and depth, not flue count.

To identify your unit: check the stamped model number on the cap skirt or mounting flange. If corrosion has eaten the stamp, measure the flue tile opening (inside dimensions, not outside) and note whether your flue is square, rectangular, or round. We carry both OEM Famco caps and stainless equivalents from Gelco and Olympia Chimney through our Haven buying network. For most Evanston installations, we recommend 304 stainless over galvanized; the salt-laden winter air off Lake Michigan chews through galvanized in 7-10 years where stainless holds 20-plus.

Signs Your Famco Chimney Cap Is Failing

• Rust streaks down the chimney face. Galvanized Famco caps eventually lose their zinc coating, especially at weld points and mesh corners. The rust runs stain brick and indicate the cap is perforated enough to let water reach the flue liner.
• Mesh clogged with creosote flakes or bird nesting. The 3/4-inch spark arrestor mesh is designed to stay open; when it’s packed solid, combustion gases back up into the firebox and smoke spills into the room on light-off. In Evanston’s older homes with shallow fireboxes, this is often the first symptom owners notice.
• Cap sits crooked or wobbles by hand. The mounting brackets or masonry screws have corroded or pulled free. A loose cap in a lakefront windstorm becomes a projectile hazard, and the gap underneath funnels rain directly onto the flue tile.
• Water in the firebox or rust on the damper. This means the cap is either missing, lifted, or has a hole large enough to pass steady water. Left through a freeze-thaw winter, that water cracks flue tiles and spalls the smoke chamber walls.
• Visible gaps between cap and flue tile. Thermal expansion and lakefront wind vibration slowly walk a poorly fitted cap out of position. Even a 1/2-inch gap is enough for squirrels to access the flue; we’ve pulled nests from Evanston chimneys where the gap was barely thumb-width.

Replacement Cost & What’s Included

The range reflects cap size, stainless grade, and whether the existing mounting surface needs repair. Every Famco chimney cap installation in Evanston includes a camera-scan inspection of the flue interior, written scope and price before work starts, and a documented photo record under Haven Standard Clause 4. We warranty the installation for 365 days; cap material defects carry the manufacturer’s warranty. We are an independent service provider, not affiliated with Famco.

DIY or Call Us?

An owner can safely check whether the cap wobbles or whether mesh is clogged from the ground with binoculars. Do not climb the roof to inspect it yourself. Steep pitches, slate or clay tile surfaces common in Evanston’s historic districts, and lakefront wind gusts make this a genuine fall hazard. If the cap is loose, it’s also unpredictable to handle at height.

Installation requires proper flue measurement (inside dimensions, not eyeball), correct fastener selection for masonry or flue tile material, and verification that the flue itself isn’t cracked beneath the cap. We’ve reinstalled caps that homeowners bought online only to find the mesh diameter was wrong for their appliance type, or the mounting legs interfered with an oversized flue liner. The camera doesn’t negotiate - and neither does creosote. Call (708) 234-1174 and we’ll quote it in writing before anyone brings a ladder.
