How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW 304/316 stainless caps: The mesh on these caps is 5/8-inch weave, which is finer than the 3/4-inch standard on most builder-grade units. In Bridgewater’s heavy oak and hickory burning country, that tighter mesh traps creosote particles faster, especially if the homeowner burns unseasoned wood from the Sourland Mountain area. We see SW caps with 40-50% airflow restriction by year three. We pull the cap, measure the mesh degradation, and either clean and reset the original or swap to a DuraFlex-compatible Gelco cap with better self-cleaning geometry if the frame is still square.
• DuraFlex DFL round flexible liner caps: The clamp-band attachment on early DFL series caps loosens with thermal cycling. Bridgewater’s freeze-thaw swings - we hit single digits most Januarys, then 50s by March - work that band harder than coastal installs. The cap tilts, gaps open, and rainwater runs straight down the flue. We don’t just tighten the band. We remove it, inspect the liner top for ovaling, install a new stainless band with proper torque spec, and seal with high-temp silicone rated to 600°F so the joint survives the next decade of winters.
• DuraFlex Pro cap base rails: The Pro series uses a two-piece base rail that slots together. The joint is concealed under the lid, so homeowners never see the rust until the rail separates and the cap starts rattling in a nor’easter. We’ve found base rails completely detached on Pro caps in the Finderne section, where older capes and colonials catch more wind off the Raritan. We replace with a solid-rail aftermarket equivalent from our Olympia Chimney inventory, or source OEM DuraFlex Pro rails when the homeowner wants exact-match parts.
• DuraFlex crown wash on factory-built chase covers: DuraFlex chase covers ship with a thin galvanized crown wash that’s painted to match. The paint fails at the drip edge first - always - and then the galvanized steel underneath rusts through in five to seven years in Bridgewater’s acid-rain pattern. We strip the failed wash, inspect the chase cover substrate for pitting, and apply a two-part CrownCoat or HeatShield repair depending on whether we’re coating over sound metal or rebuilding a rotted edge. We show you the photos before we choose.
• DuraFlex multi-flue cap alignment: The multi-flue caps in the DuraFlex lineup use a single lid over two or three flue collars. When one flue settles or shifts - common in the 1960s-1980s split-levels around Green Knoll - the collar gasket compresses unevenly and the lid sits cockeyed. Water pools on the low side. We don’t shim and hope. We measure each flue centerline, fabricate or order a cap with adjustable collars, and set it plumb so drainage runs to all four corners.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing (water stains, rust flakes, animal intrusion, draft problems), and books a Level-2 camera inspection. We quote the inspection fee upfront - no surprises.
2. 2
   Inspection and documentation. Our tech arrives in uniform, runs a camera from the firebox to the cap, and photographs the crown surface, cap attachment, and flue condition. You see the images on a tablet before we leave the roof. We give you a plain-English verdict: what’s failing, why it’s failing, and what happens if you wait.
3. 3
   Parts decision. For DuraFlex systems, we check OEM availability against our inventory of compatible HeatShield, Gelco, and Olympia Chimney components. If your cap is under any remaining manufacturer warranty, we note that and use OEM parts to preserve coverage. If not, we recommend the part that solves the problem longest for the dollar - sometimes that’s aftermarket, sometimes it’s DuraFlex direct.
4. 4
   The repair. Most cap replacements and crown coatings take two to four hours. We protect your roof and landscaping, remove the failed component, address any substrate damage we found, install the new cap or apply the crown coating per manufacturer spec, and torque every fastener.
5. 5
   Testing and walkthrough. We run a draft test, verify cap clearances, and show you the finished work. You get a photo report, a written invoice matching your estimate, and the 90-Day Done Right Promise in writing. If it’s not right, we make it right - no paperwork, no arguing.
6. 6
   Cleanup and follow-up. We haul away the old cap and debris. Our office calls within two weeks to confirm you’re satisfied. The chimney doesn’t lie. Neither do we.

Why Bridgewater Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We’ve been answering the phone with a live person for over 42 years, and we’ve worked on DuraFlex systems since the brand first showed up in Somerset County new construction in the late 1990s. Russell Haines and our crew know the difference between a DuraFlex SW and a DuraFlex Pro cap without reading the stamp - we’ve replaced enough of both to spot the failure pattern from the ground.

Our 90-Day Done Right Promise means if the cap leaks or the coating cracks, we come back. In writing, no arguing. Our technicians are background-checked and uniformed, and most DuraFlex cap and crown jobs finish in one visit because we stock the common sizes and compatible HeatShield and Gelco alternatives. We’re not a chain, and we’re not a one-truck operator who might answer next year. We’re the company that plans to be sweeping chimneys in Bridgewater thirty years from now. That changes how we treat every job.
