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.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall) liners crack at the flex-to-rigid transition in Framingham’s freeze-thaw cycle. The corrugated wall flexes fine, but the factory weld where it meets the rigid starter section work-hardens over five to seven winters. We cut back to sound metal, source a DuraFlex-compatible rigid starter through our Haven buying network, and document the repair with before-and-after camera footage under Clause 4.
- DuraFlex Pro liners sag in tall, exterior chimneys common near Cushing Memorial Park, where 1920s colonials run flues three stories up an outside wall. The Pro’s lighter gauge saves money upfront but lacks the structural memory of heavier alloys. We find the sag with a laser plumb during camera inspection, then install a DuraFlex-compatible support plate or recommend upgrading to a heavier liner if the offset exceeds NFPA 211 limits.
- DuraFlex AL (aluminum) gas venting corrodes at condensate collection points when furnaces or gas inserts run short cycles. The aluminum resists standard flue gases but not the nitric acid condensate that pools in low spots. We map the condensate pattern with the camera, replace affected sections with OEM or Olympia Chimney equivalent, and re-pitch the run so it drains.
- DuraFlex insert boots fail at the seal collar where the flexible liner meets a wood-burning insert. Thermal cycling and ash abrasion wear the gasket; smoke then leaks into the chase. We carry replacement boots in common diameters, but we also check whether the insert itself is overfired - a Framingham issue we see when homeowners burn seasoned oak too hot in small fireboxes.
- DuraFlex telescoping sections seize after years of creosote glazing, especially on north-facing chimneys that never fully dry out. The telescoping joint is meant to adjust for height during install, but once Class III creosote glues it shut, the liner can’t be pulled for inspection. We break the glaze with mechanical brushing - never chemical shortcuts that void DuraFlex’s material warranty - then document free movement before reassembly.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers. We ask the model if you know it, the fuel type, and what you’re seeing. Corrine Halstead or her dispatch assigns a named tech and texts you when they’re en route.
- 2
NFPA 211 Level 2 inspection with camera. We drop the camera the full flue length. For DuraFlex systems, we specifically check flex points, weld zones, and support spacing. You watch the feed if you want. The camera doesn’t lie, and neither does the written estimate.
- 3
Written price, scope, and warranty before work starts. Haven Standard Clause 1: have it in writing. We list OEM versus quality aftermarket options, explain the trade-offs, and note anything that can safely wait.
- 4
Repair with documented photo record. We use DuraFlex, HeatShield, Gelco, or equivalent materials sourced through our Haven buying network. Every step is photographed for your record under Clause 4.
- 5
Post-repair test burn or draft measurement. Gas systems get combustion analysis; wood systems get a visual test burn and draft reading. We don’t leave until the numbers match spec.
- 6
Cleanup, documentation, and 365-Day Done Right Promise. You get photos, readings, the written warranty, and our promise: if it’s not done right, we make it right.

Why Framingham Homeowners Call Level Two Chimney Framingham for DuraFlex Work

We’ve inspected over 38,000 chimneys since 2009, and a growing share of Framingham’s housing stock - the 2015-to-2025 buyer cohort especially - runs DuraFlex venting for gas inserts and wood conversions. Corrine Halstead learned the trade in New York City College of Technology’s masonry program, then spent the better part of two decades on roofs across MetroWest, including the older colonials near Cushing Memorial Park that throw a surprise at every camera drop. Her regular customers seem to prefer that she’s usually the one answering the phone.
We don’t sell DuraFlex, and we’re not affiliated with or authorized by them - we’re an independent DuraFlex service provider. What we do have is a documented photo record on every visit (Clause 4, Haven Standard), a Free Second Opinion on any competitor’s written estimate, and materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield procured through our buying network to keep prices honest. The 365-Day Done Right Promise is stamped on every job.
FAQs
No. DuraFlex’s material warranty covers manufacturing defects regardless of who installs or services the product, provided the work meets NFPA 211 and local code. We document our methods and materials so any warranty claim you file later has full backup. If you’re unsure about your specific warranty terms, we can review them during inspection and note anything that affects coverage. Call (508) 850-0489 to schedule.
Common DuraFlex boots, support plates, and liner sections ship to our Framingham warehouse within two to three business days through our Haven buying network. For less common diameters or the heavier-gauge Pro line, allow four to five days. We don’t start work until parts are in hand - no partial repairs that leave you without heat. We’ll tell you the exact lead time in your written estimate.
A single crack or failed weld in an otherwise sound liner can often be section-repaired. We make the call based on camera findings: crack length, location relative to supports, overall liner age, and creosote loading. If the liner has multiple failure points, sag, or wall thinning below 20-gauge equivalent, we recommend replacement and show you the camera evidence so you can decide. Nothing is pushed without documentation.
NFPA 211 calls for annual inspection of all chimney systems, and Framingham’s freeze-thaw cycle plus oak-heavy burning habits make that worth following. Gas systems vented through DuraFlex AL should be checked for condensate corrosion every year; wood systems with stainless liners need creosote stage assessment and camera documentation of flex points. We flag what can wait and what can’t, in writing.
DuraFlex specializes in flexible stainless and aluminum liners and venting components. HeatShield is a cerfractory flue resurfacing system for restoring clay tile liners without full replacement. Gelco makes caps, dampers, and chase covers. We work with all three - and cross-match where it saves you money - but on DuraFlex jobs we stay with DuraFlex-compatible materials for liner work unless you request otherwise and we confirm the substitution is safe.
