Most DuraFlex jobs are diagnosed and quoted within one visit, with a written price delivered before any work starts.

Call (720) 674-7312

This page is for Denver homeowners who’ve found a DuraFlex tag on their fireplace component and want to know whether it can be fixed, what it’ll cost, and whether the fix will outlast the next burning season. If that’s you, call (720) 674-7312. Estimates are free, and we answer live 24/7.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wall-flex) liner: creosote bridging at the flex joints. In Denver’s dry, high-altitude climate with rapid temperature swings, the corrugations in SW liner collect glazed creosote faster than smooth-wall alternatives. We see this most in wood-burning installs in Baker and Highland, where owners burn pine and compressed logs. Our fix: rotary cleaning with poly or chain whips sized to the corrugation depth, followed by a Level 2 camera scan to confirm the valleys are clean. If the liner has thinned at the flex points, we quote replacement with DuraFlex Pro or a smooth-wall alternative from our Haven network.
• DuraFlex AL (aluminum) liner: premature corrosion in gas fireplace conversions. AL was spec’d for Category I gas appliances, but Denver’s altitude drops combustion efficiency and raises condensation in marginal installs. We find AL liners deteriorated above the smoke chamber in Park Hill and Stapleton homes where original builders cheaped out. Our fix: pull the AL, inspect the surrounding masonry for chloride staining, and replace with DuraFlex Pro stainless or an Olympia Chimney equivalent rated for the actual appliance input. We write the scope before we touch a tool.
• DuraFlex Pro termination caps: wind-driven downdraft and debris infiltration. The Pro cap’s mesh screen is finer than competing brands, which is good for spark arresting but bad when cottonwood seed clogs it in May and June. We’ve pulled caps in Cherry Creek that were 60% blocked. Our fix: clean or replace the cap, and if downdraft persists, we source a Gelco wind-resistant cap or fabricate a custom cricket from Copperfield stock. We show you the blockage on camera before recommending anything.
• DuraFlex insert adaptors: gasket fatigue and smoke spillage. The factory gasket between DuraFlex insert liners and the appliance collar hardens after 5-7 years of Denver’s freeze-thaw cycles. Owners smell smoke at startup or see soot on the hearth. Our fix: replace with OEM DuraFlex gasket kits where available, or fabricate a compression seal from Famco high-temp gasket material. We test with a smoke pencil and draft gauge before we leave.
• DuraFlex chimney relining systems: unsupported horizontal offsets in fireplace conversions. When a DuraFlex liner is pushed through a masonry chimney with an offset, the flex can sag or ovalize if the installer didn’t use support brackets at code spacing. We find this in pre-1950s homes in Capitol Hill and Berkeley where the original flue has a dogleg. Our fix: install DuraFlex support brackets or transition to a rigid stainless section through the offset, documented with pre- and post-install camera runs. Clause 4 of the Haven Standard requires that photo record.

Our DuraFlex Fireplace Services Process

1. 1
   Call and schedule. A live person answers, checks our calendar, and notes your DuraFlex model if you have it. We text you the assigned tech’s name and photo before dispatch.
2. 2
   NFPA 211 Level 2 inspection on arrival. Camera down the flue, readings taken, condition documented. Corrine Halstead started this practice in 2009, and it’s now Haven Standard Clause 4. The camera doesn’t guess. Neither do we.
3. 3
   Written price, written scope, written warranty. Before any work starts, you get a flat price with line items, the exact parts we’ll use (OEM DuraFlex or equivalent from HeatShield, Gelco, or Olympia Chimney), and the 365-Day Done Right Promise in writing. Haven Standard Clause 1: have it in writing.
4. 4
   Repair or replacement with documented steps. Techs work in uniform, license number visible, with parts sourced through our Haven buying network. We photograph critical stages.
5. 5
   Post-repair testing and final documentation. Smoke test, draft measurement, and a photo record of the completed work delivered to you. If we converted a wood-burning fireplace to gas, we verify appliance-specific venting with a manometer.
6. 6
   Cleanup and archive. We leave the work area as found, and your documented record goes into our archive - 38,000+ jobs and counting since 2009.
