This page is for Cambridge homeowners who bought a Copperfield chimney cap or crown in the last 5-15 years and need to know whether it can be repaired, what replacement costs, and who’s qualified to work on it without voiding whatever warranty remains.

How Copperfield Products Fail - and How We Fix Them

• Copperfield Multi-Flue Series - screen separation at the weld seam. The expanded metal mesh on Multi-Flue caps is spot-welded to a galvanized frame, and in Cambridge’s freeze-thaw cycle, those welds fatigue faster than solid-frame designs. We see this most on roofs in North Cambridge and Porter Square where the cap catches afternoon sun then overnight frost. Our fix: cut out the failed mesh, fabricate a replacement section from heavier-gauge stainless, and attach with mechanical fasteners - not welds - so the joint can flex.
• Copperfield Single-Flue Draft King - base rail rust-through. The Draft King’s galvanized base rail sits in the flue’s top course of brick, and if the crown was never sealed with silicone, acidic condensate pools against that rail. In Cambridge’s older housing stock, especially the triple-deckers between Inman Square and Union Square, we’ve pulled Draft Kings where the rail was paper-thin after eight years. We replace with a stainless base rail and re-bed the cap in proper crown sealant - not caulk, which hardens and cracks.
• Copperfield Stainless Draft King - lid hinge pin seizure. The hinge pin on lid-style Draft Kings is 304 stainless, but the bushing is often mild steel. Salt air from the Charles River corridor accelerates galvanic corrosion, and the lid freezes open or shut. We drill out the seized pin, replace with all-316 stainless hardware, and grease with high-temp anti-seize so the lid operates through another decade of Cambridge winters.
• Copperfield Chimney Crown - surface spalling from trapped moisture. Copperfield crowns are poured concrete, and when the factory seal coat fails, water migrates through freeze-thaw cycles. The surface flakes off in sheets - spalling - exposing aggregate and accelerating deterioration. We grind to sound concrete, apply a bonding agent, and trowel on a polymer-modified crown coat rated for 200 freeze-thaw cycles, which is what Cambridge averages in a hard winter.
• Copperfield Custom Caps - fastener loosening on standing seam attachment. Custom caps with standing seam sides rely on concealed fasteners, and thermal expansion works them loose over seasons. We’ve found caps on Harvard Square-area homes where the seam had gapped enough to let squirrels nest. We remove, re-bed in butyl tape, and fasten with expansion-rated screws at 6-inch centers - closer than factory spec - because Cambridge’s temperature swing from January to July is 100 degrees plus.

Our Copperfield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks our Cambridge route schedule, and books a two-hour arrival window. You get a text when your tech is en route.
2. 2
   NFPA 211 Level 2 inspection with camera. We run the camera down the flue before touching the cap or crown. Corrine Halstead’s rule: the camera doesn’t editorialize - it just shows you what’s there. We document liner condition, smoke chamber integrity, and any water damage that started at the crown.
3. 3
   Written price, written scope, written warranty. Before any work, you receive a single-page document with line-item pricing, the exact parts we’ll use (OEM Copperfield or equivalent from our Haven buying network), and the 365-Day Done Right Promise. Clause 1 of the Haven Standard: have it in writing.
4. 4
   Parts procurement through Haven network. For current Copperfield lines, we source OEM through our distributor. For discontinued series, we fabricate from stainless or source equivalent through Olympia Chimney or Gelco - always disclosed, never substituted without your sign-off.
5. 5
   Repair or replacement with photo documentation. We complete the work, run the camera again to verify flue condition post-repair, and upload photos to your job record. Haven Standard Clause 4 requires this documentation on every visit - we’ve done it since 2009.
6. 6
   Cleanup and final walkthrough. The tech reviews the photo record with you, confirms the lid operates freely (on hinged models), and leaves the written warranty in hand. Payment is due only after you’re satisfied.

Why Cambridge Homeowners Call Level Two Chimney Cambridge for Copperfield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those were Copperfield caps and crowns in Cambridge’s pre-war housing stock. Our techs know the difference between a Draft King and a Multi-Flue by sight, know which series used mild steel bushings, and know how Cambridge’s freeze-thaw cycle and Charles River humidity affect each.

We’re an independent Copperfield service provider - not affiliated with or authorized by the manufacturer - which means we work for you, not their warranty department. When OEM parts make sense, we source them through our Haven buying network. When they don’t, we have DuraFlex, HeatShield, and Gelco equivalents at comparable or better specs, and we tell you which is which before you decide.

The 365-Day Done Right Promise applies to every job. The documented photo record is standard, not an upsell. And the price you see before work starts is the price you pay - Clause 1, no exceptions.
