Copperfield Chimney Cap Installation Nationwide

Copperfield Chimney Cap Installation: The Arlington Heights Owner’s Guide

We stock and install Copperfield-compatible chimney caps across Arlington Heights, typically running $340-$680 installed depending on flue size and whether your crown needs remediation. Most Copperfield cap replacements in this area are completed in a single visit, and we carry the common 8″×13″ through 13″×18″ galvanized and stainless models on our trucks. Arlington Heights homeowners usually discover the problem after a windstorm off the Des Plaines River valley sends the cap sailing into the neighbor’s yard, or when water starts dripping down the flue during a March thaw.

Which Copperfield Models This Applies To

Copperfield caps break down into three series you’ll see around Arlington Heights: the standard galvanized line (black finish, 5-year warranty), the 304 stainless series (natural or powder-coated, lifetime warranty), and the smaller 6″ and 7″ round models built for factory-built chimneys. The label is stamped on the underside of the lid or on the mesh skirt - look for a part number starting with “CF-” followed by the nominal flue dimension.

Here’s where owners get tripped up: Copperfield measures by flue tile opening, not crown width. A cap marked “13×18″ fits a flue tile measuring roughly 12.5″ by 17.5” inside the chimney top. Measure wrong and you’ll get a cap that perches like a hat on a dog. We see this constantly on the older colonials near Campbell Street where flue tiles have shifted or been repaired with non-standard replacements.

We source Copperfield caps through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco materials. For most Arlington Heights installations, the OEM Copperfield stainless cap is the right call; the galvanized version saves about $90 upfront but starts showing rust at the skirt welds around year four in our freeze-thaw climate. We keep both in stock.

Signs Your Copperfield Chimney Cap Is Failing

• Visible rust streaks down the chimney face. Copperfield galvanized caps use a baked-on finish that fails first at the skirt-to-lid weld. Once moisture hits bare steel, the cap becomes a funnel directing water into your flue rather than away from it. We catch this on camera inspections more often than homeowners do from the ground.
• Mesh sides pulled away or flattened. Squirrels and raccoons in Arlington Heights treat chimney cap mesh like a puzzle box. Copperfield’s ¾” mesh is sturdy but not chew-proof. A gap larger than a quarter means embers can exit and animals can enter - both bad outcomes we document under Clause 4 of the Haven Standard.
• Cap sitting crooked or rocking on the flue. The mounting brackets on older Copperfield models use a tension-screw design that loosens as flue tiles expand and contract through our Illinois winters. A cap that shifts in the wind is a cap that’s already partially detached.
• Water staining on the firebox ceiling or smoke chamber walls. This shows up in our camera footage as white efflorescence or rust streaks on the liner. The cap’s not keeping water out, and every rain event pushes moisture deeper into the masonry freeze-thaw cycle.
• Missing cap entirely after high winds. Arlington Heights sits in a wind corridor between O’Hare’s approach patterns and the Des Plaines River valley. Copperfield caps with corroded mounting brackets or improperly sized bases don’t need a tornado - a 45-knot March gust will do the job.

Replacement Cost & What’s Included

The range depends on three things: cap material, whether your flue tile is standard dimension or has been modified by previous repairs, and whether the crown surface needs re-washing before the new cap mounts securely. We deliver a written price before any work starts - Haven Standard Clause 1 - and that price includes the cap, installation, a camera inspection of the flue top, and a photo record of the completed work under Clause 4.

Every cap we install carries the 365-Day Done Right Promise. If it leaks, shifts, or fails, we make it right.

DIY or Call Us?

You can safely check three things from the ground: whether the cap is present, whether it’s sitting level, and whether you see rust or mesh damage. Use binoculars. Don’t climb.

Here’s why: chimney cap installation requires working at height on a surface that may be slick with algae, moss, or ice - common on north-facing Arlington Heights roofs well into April. The mounting brackets on Copperfield caps require precise tension; too loose and the cap departs in the next wind event, too tight and you crack the flue tile. We’ve replaced caps that were “installed” with self-tapping screws driven straight into crown concrete, which guarantees water intrusion and crown failure within two seasons.

The camera doesn’t guess. Neither do we. Call (331) 202-2419 and we’ll scope the flue top, measure the flue tile precisely, and give you a written price before anyone touches a ladder.
