Copperfield Chimney Cap Installation Nationwide

Copperfield Chimney Cap Installation: The Allentown Owner’s Guide

We stock and install Copperfield-compatible chimney caps across Allentown, with most replacements running $285 to $495 installed depending on flue size and whether your crown needs resealing. Most jobs we book are completed in a single visit because our trucks carry the common Copperfield sizes, including the 8″×13″ through 13″×18″ galvanized and stainless ranges that fit the majority of Lehigh Valley brick chimneys. Homeowners usually figure out something’s wrong when water starts showing up on the firebox floor after a hard rain, or when they spot rust streaks running down the brick from a cap that’s been baking on an Allentown south-facing roof for fifteen summers.

Which Copperfield Models This Applies To

Copperfield has manufactured chimney caps under a few different series names over the years, and the label matters when you’re matching a replacement. The most common we see in Allentown are the standard galvanized single-flue caps, the stainless steel wind-resistant models, and the older “Chimney Cap by Copperfield” line that was sold through hearth retailers in the 2000s. If your cap still has a label, check for a model prefix like CCM or CCF - those tell us the mounting style and whether you have bolt-on or clamp-on legs.

Here’s the compatibility gotcha: Copperfield used two different leg spacings on their 13″×18″ caps depending on whether the unit was made for their retail line or their contractor-supply channel. The legs look identical until you set the cap on the flue tile and find the clamp brackets miss by half an inch. We measure on-site with a leg-spacing gauge before pulling anything off the truck. For OEM-versus-aftermarket, we generally install Copperfield-spec caps from Olympia Chimney or Famco that match the original dimensions and gauge - same performance, no branding markup. Hearthstone Chimney Co. is an independent service provider, not affiliated with Copperfield.

Signs Your Copperfield Chimney Cap Installation Is Failing

• Rust stains on the brick below the cap. Copperfield galvanized caps have a baked-on finish that holds up reasonably well, but once the coating cracks at a corner seam, the Lehigh Valley freeze-thaw cycle opens it wider every winter. We see this most often on caps installed before 2010.
• Water in the firebox or a musty smell after rain. The mesh screen on a Copperfield cap can sag over time if the cross-weld corrodes, creating a low spot where water pools and drips straight down the flue. In Allentown’s older homes near West Park, we’ve found caps where the screen had detached entirely on one side.
• The cap is tilting or has shifted on the flue. Copperfield clamp-on models rely on two L-brackets with stainless bolts. When those bolts seize from rust, homeowners sometimes try to force them and strip the threads - or worse, the cap lifts in a wind gust because it was never tight to begin with.
• Animals or birds getting in. A cap with damaged mesh, or a cap that was never the right size and leaves a gap at the flue tile edge, is an open door. We’ve pulled squirrel nests from flues in Allentown where the original Copperfield cap was two inches oversized and the clamp legs never seated flat.
• Spalling brick or deteriorated mortar at the chimney top. This isn’t the cap itself failing, but it’s why the cap failed to protect. A cap that sheds water poorly, or was installed without a proper drip edge, lets moisture work behind the brick face. By the time you notice the cap problem, the crown underneath may need attention too.

Replacement Cost & What’s Included

What drives the range: flue size and height access are the big two. A standard 8″×13″ on a single-story ranch in Whitehall Township is straightforward. A 13″×18″ on a three-story colonial in Allentown’s West End, with a steep roof pitch and a chimney that’s been tuckpointed twice, takes longer and requires additional ladder staging. Our estimate includes the cap, stainless fasteners, a bead of high-temp silicone at the flue tile joint, and disposal of the old unit. Every installation carries our 90-Day Done Right Promise - in writing, no arguing. The number on the estimate is the number on the invoice.

DIY or Call Us?

There’s a safe middle ground here. You can check your cap’s fit from the ground with binoculars: look for tilt, rust streaks, or mesh that’s pulled away from the frame. You can also measure your flue tile opening from inside the firebox with a flashlight and tape measure - outside dimensions of the terracotta, not the firebox opening. That measurement tells us what size cap to bring.

What we don’t recommend: climbing the roof to loosen seized bolts, or trying to force a new cap onto a flue tile that’s cracked or uneven. We’ve been called to jobs in Allentown where a homeowner bought the right cap but couldn’t get the clamp legs square, so they caulked it in place. That cap blew off in the first March wind. The chimney doesn’t care what it looks like from the street. We check what’s inside. If you’re not comfortable on a roof with a tool bag, call us at (610) 632-1394. We’ll give you a straight price and a date we plan to keep.
