Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Liner & Rebuild in Wakefield: What to Know First
We provide independent DuraFlex chimney liner and rebuild service in Wakefield, with most liner replacements completed in one to two days and partial or full rebuilds scheduled within a week of your written approval. Every job starts with a camera-scan inspection and ends with a documented photo record, a written warranty, and a fixed price you saw before anyone picked up a tool. If you own a DuraFlex liner or suspect yours needs attention, call us at (978) 861-1012 for a free estimate. We’ll show you what the camera found, explain what it means, and give you a written price before any conversation about what to do next.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless flexible liner) - crevice corrosion at the flex joints. Wakefield’s freeze-thaw cycles let moisture settle into the corrugation valleys of older SW runs, especially where the liner passes through an uninsulated exterior chase. We pull the damaged section, inspect the full run with a camera, and replace with new DuraFlex SW or transition to a rigid DuraFlex SS liner if the straight shot allows it.
- DuraFlex Pro - premature mortar joint failure in the surround. The Pro’s interlock is solid, but the refractory surround can crack when the chimney crown above it has been leaking for seasons. We see this in Wakefield colonials near Lake Quannapowitt where the crown looks fine from the ground but channels water behind the brick. We rebuild the crown, replace the surround, and re-line with matching DuraFlex Pro or HeatShield Cerfractory foam if the flue body is sound.
- DuraFlex AL (aluminum) - heat distortion above the smoke chamber. Aluminum liners in gas setups can belly or separate at the collar where they meet a factory-built fireplace. The distortion shows up on camera as a shadow ring that doesn’t change with the light angle. We replace the AL section with DuraFlex AL-29-4C or upgrade to stainless if the appliance output has changed since original install.
- DuraFlex SS (rigid stainless) - spalled tile fragments lodged at offsets. Rigid liners don’t flex past debris. When a clay flue sheds spalls into the gap, the SS pipe hangs up during inspection and can’t be cleaned properly. We extract the liner, clear the flue body, and reinstall with proper clearances per DuraFlex’s 1/2-inch rule, or recommend a partial rebuild if the flue wall is too compromised.
- DuraFlex termination caps - wind-driven rain infiltration through corroded mesh. The cap’s 304 stainless mesh degrades faster on ocean-facing exposures, and Wakefield gets enough salt-laden nor’easters to matter. We source OEM DuraFlex caps through Haven’s buying network or fit a Gelco cap with equivalent spark arrestor rating, documenting the substitution on your record.
Our DuraFlex Chimney Liner & Rebuild Process

- 1
Camera-scan diagnosis (NFPA 211 Level 2). We run the camera the full flue length, record the footage, and mark timestamps for any DuraFlex-specific damage. You get a copy.
- 2
Written scope and price. Corrine Halstead or a senior tech builds the estimate: parts, labor, timeline, and warranty terms. No work starts until you have it in writing. Haven Standard Clause 1.
- 3
Parts procurement - OEM or quality aftermarket. We source DuraFlex direct when the series is current and the lead time is reasonable. For discontinued lines or faster turnaround, we specify HeatShield or Gelco equivalents with matching UL 1777 listings and note the substitution on your record.
- 4
Installation or rebuild. Liner pulls happen top-down or bottom-up depending on roof access and interior finish protection. Rebuilds follow a staged tear-off with daily photo logs.
- 5
Smoke test and final camera pass. We verify draft, check for leaks at joints and collars, and run the camera one more time to confirm the new liner’s full-length integrity.
- 6
Documentation and warranty. You receive the photo record, the smoke test result, and the written warranty under our 365-Day Done Right Promise. Haven Standard Clause 4, archived since 2009.

AfterWhat DuraFlex Chimney Liner & Rebuild Costs in Wakefield
| Scenario | Typical Range |
|---|---|
| DuraFlex SW liner replacement, single flue, standard height | $2,800 - $4,200 |
| DuraFlex Pro surround rebuild with re-line | $4,500 - $6,800 |
| Partial chimney rebuild (crown to roofline) with new DuraFlex liner | $7,500 - $12,000 |

| DuraFlex cap replacement only | $380 - $650 |
What moves the price: flue height, access difficulty (steep pitch, tight chase), whether the existing liner can be extracted intact or must be cut out, and whether the clay flue body needs parging or full rebuild before the new liner goes in. We don’t guess. We camera-scan first, then write the price. Call (978) 861-1012 for a free estimate.
Why Wakefield Homeowners Call Level Two Chimney Wakefield for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when it was done. Our technicians are background-checked, uniformed, and assigned by name - you’ll get a text when yours is on the way. We know DuraFlex’s product lines because we’ve pulled, replaced, and rebuilt them in Wakefield homes for years, including the older colonials near the lake where clay liner damage hides behind clean brick. When DuraFlex parts are back-ordered, we don’t leave you hanging: our Haven buying network stocks HeatShield and Gelco equivalents with matching listings. And if another company handed you a quote that doesn’t sit right, bring it in. Our Free Second Opinion is exactly that - free, written, and no obligation.
Here’s what the camera found. Here’s what it costs to fix it. Everything else can wait.
FAQs
No - DuraFlex’s warranty covers manufacturing defects, not who installs or services the liner. As an independent DuraFlex service provider, we document every step with photos and written scope, which actually strengthens any future warranty claim by establishing a maintenance record. If you’re unsure about your specific warranty status, call us at (978) 861-1012 and we’ll review it with you.
The camera decides: isolated cracks or collar separation often allow spot repair, but crevice corrosion along multiple flex joints or heat distortion over 12 inches means replacement is the sound choice. We show you the footage, explain the failure mode, and write both options if both exist. Call (978) 861-1012 for a free camera inspection.
Most current DuraFlex SW and SS components arrive within three to five business days through our Haven buying network. Discontinued lines or specialized Pro surrounds may take longer, in which case we quote a HeatShield or Gelco equivalent with matching UL listing and your approval. We never start work with parts in limbo.
A standard single-flue replacement is typically one day of active work, plus a half-day for the smoke test and final camera pass. Partial or full rebuilds run three to five days depending on weather and masonry cure times. We schedule only what we can complete, and we don’t book your job until parts are confirmed in hand.
A compromised DuraFlex liner can leak combustion gases including carbon monoxide into wall cavities or living space, and creosote can reach combustible framing if the liner gap opens. The risk is real, but we don’t scare-sell: we show you the camera evidence, explain the specific hazard for your setup, and note if the work can safely wait until next season. Call (978) 861-1012 for the inspection that lets you decide from facts.
