Call (331) 200-4445

This page is for Hoffman Estates homeowners with a DuraFlex liner, cap, or chimney component that’s leaking, separating, or showing wear after five to fifteen years in service. If you’re seeing water stains near the fireplace, smelling smoke indoors, or your sweep flagged a liner issue, call us at (331) 200-4445. We’ll send a camera down, show you what we found, and hand you a flat price before anyone picks up a tool.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (Stainless Wall) liner separation at the tee connection. The SW’s single-wall flex construction expands and contracts aggressively during Hoffman Estates freeze-thaw cycles, and the tee body can work loose where it meets the flex run. We find gaps of 1/4 inch or more that vent flue gases into the chimney cavity. Our fix: remove the tee, reseat with a DuraFlex-compatible adapter and high-temp sealant, then pressure-test the joint.
• DuraFlex HT (Heavy Wall) liner crevice corrosion at the cap. The HT’s heavier gauge holds up well in the flue, but the upper termination sits in concentrated condensation where the cap meets the liner top. We see this on north-facing chimneys in Hoffman Estates subdivisions near Hilldale Golf Club, where sun exposure is limited and moisture lingers. We cut back the damaged section, install a new DuraFlex-compatible top plate, and verify draw with a draft gauge.
• DuraFlex AL (Aluminum) liner sag in tall, uninsulated chases. The AL series is lighter and more flexible, which means it can belly or sag in vertical runs over twenty feet without proper support spacing. We encounter this in Hoffman Estates townhomes with framed chases built in the 1990s. Our repair involves adding support rings at code spacing, re-tensioning the liner, and documenting the new configuration with photos per Haven Standard Clause 4.
• DuraFlex relining collar mortar decay. The collar that seals the liner to the chimney crown relies on the crown’s mortar bed. When that bed cracks - common after Hoffman Estates winters with repeated freeze-thaw - water runs behind the liner. We repoint or rebuild the crown, reseat the collar with fresh refractory mortar, and verify the seal with a water test.
• DuraFlex chimney cap mesh collapse. The factory mesh on older DuraFlex caps can fatigue and drop into the flue, blocking draft and creating a carbon monoxide risk. We’ve pulled collapsed mesh from caps installed during the 2005-2012 building boom in Hoffman Estates neighborhoods like Highland Woods and Winston Knolls. We replace with a Gelco or Famco stainless cap sized to the DuraFlex termination, or source OEM DuraFlex caps through Haven’s network when the customer prefers.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers, checks availability, and notes your DuraFlex model if you know it. We don’t require it - we’ll identify it on site.
2. 2
   Camera-scan inspection. We run an NFPA 211 Level 2 inspection with a chimney camera down the full flue length. Corrine Halstead’s rule: camera first, price second, pen third - in that order every time.
3. 3
   Parts decision. We show you the footage, name the failure, and recommend OEM DuraFlex or quality aftermarket from HeatShield, Gelco, or Olympia Chimney based on availability, warranty status, and your budget. No parts are ordered without your written approval.
4. 4
   Written price and scope. Haven Standard Clause 1: you get a written price, written scope, and written warranty before work starts. Not after. Not when the tech is already on your roof.
5. 5
   Repair and test. We complete the repair, run a draft test or smoke test as appropriate, and verify all connections with a mirror and camera follow-up.
6. 6
   Documentation and cleanup. Haven Standard Clause 4 requires a photo record on every job. You receive dated photos, a condition report, and the 365-Day Done Right Promise in writing. Then we sweep the work area.

Why Hoffman Estates Homeowners Call Level Two Chimney Hoffman Estates for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those were relined with DuraFlex products during the 2000s and 2010s building waves in Hoffman Estates, Schaumburg, and Palatine. We know which subdivisions have which installations because we’ve been on those roofs.

Our technicians are background-checked, uniformed, and assigned by name - you’ll get a text when yours is on the way. Every repair carries the 365-Day Done Right Promise: if it’s not done right, we make it right. And if another company handed you a written estimate that doesn’t sit right, Haven Standard Clause 5 covers you: free second opinion, any written quote, no obligation.

We also service HeatShield and Gelco systems, so if your DuraFlex component interacts with another brand’s part - common with caps and dampers - we don’t need to call in a second contractor.
