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.

AfterDuraFlex Chimney Cap & Crown in Arlington Heights: What to Know First
We provide independent DuraFlex chimney cap and crown service in Arlington Heights, with most repairs scheduled within a few days and every job quoted in writing before we start. A standard DuraFlex cap replacement runs $340-$580, crown repair $480-$920, and you’ll see camera evidence of the problem before any work is approved. This page is for homeowners who already know they’ve got a DuraFlex liner or cap system and need someone who won’t treat it like generic sheet metal. We stock DuraFlex-compatible caps and crown coating materials through our Haven buying network, and Corrine Halstead’s crew has handled enough of these to know which series cracks at the collar and which ones just need the storm collar resealed. Call (331) 202-2419 for a free estimate, or bring us a competitor’s written quote for our free second opinion.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wrap) collar separation at the flue top. The SW’s interlocked seam can work loose where the cap collar meets the flue wall, especially after Arlington Heights winters with freeze-thaw cycling off the Des Plaines River valley. We see this on homes near Recreation Park where the wind exposure is worse. We pull the cap, reseat the collar with DuraFlex-compatible stainless banding, and install a proper overlap-fit cap rather than a friction-only replacement.
- DuraFlex Pro oval-to-round adapter gaps under multi-flue caps. The Pro line’s ovalized termination can leave a 3/8-inch gap at the adapter when a standard round multi-flue cap is forced on. Water pools there, freezes, and spalls the crown edge by spring. We measure the oval minor axis on-site and source either a DuraFlex OEM oval cap or a custom-fabricated Gelco equivalent through our Haven network.
- DuraFlex 316Ti storm collar corrosion at the weld. The titanium-stabilized 316Ti resists acid well but the spot-welded storm collar is a different alloy and can pit where creosote drips collect. We replace with a seamless, roll-formed collar in matching 316Ti rather than patching with generic galvanized, which voids the liner warranty and fails again in two seasons.
- DuraFlex relining top plate distortion from over-tightened retrofit caps. Homeowners or roofers who install big-box caps with lag screws often torque down on the DuraFlex top plate, deforming the seal surface. The plate looks fine from the roof edge but leaks at the storm collar. We camera-scan to confirm plate integrity, then replace the cap with a clamp-style model that doesn’t load the plate.
- DuraFlex crown washout at the flue penetration. The DuraFlex termination kit includes a standard crown seal, but Arlington Heights’ clay-heavy soils let moisture wick up through chimney bases and the crown wash accelerates spalling at the flue center. We grind back to sound concrete, apply a sloped CrownCoat or HeatShield repair, and lap the DuraFlex storm collar 2 inches minimum over the new surface.

Written scope and price. Corrine Halstead’s tech shows you what the camera found, explains whether you need OEM DuraFlex parts or if a quality aftermarket cap from Gelco or Famco meets spec, and delivers a written price before any work starts. Clause 1 of the Haven Standard: have it in writing.

Repair or replacement. We install the cap or repair the crown using materials sourced through our Haven buying network. For DuraFlex systems, we verify storm collar overlap and cap clearance to spec. No shortcuts on fasteners or sealants.

Why Arlington Heights Homeowners Call Level Two Chimney Arlington Heights for DuraFlex Work
We’ve run camera inspections on more than 38,000 chimneys since 2009, and a healthy share of those have been DuraFlex systems in the northwest suburbs. Corrine Halstead grew up in Queens, learned the trade at Apex Technical School in Manhattan, and built a crew that knows the difference between a DuraFlex SW collar separation and a top plate distortion without guessing. The camera doesn’t guess. Neither do we.
Our techs are background-checked, uniformed, and carry license information you can verify. You get a written price before work starts, a documented photo record when it’s done, and the 365-Day Done Right Promise backed by the Haven Standard. If we don’t stock your exact DuraFlex OEM part, we pull from HeatShield, Gelco, or Famco equivalents that meet or exceed spec, not whatever’s cheapest at the supply house. And if another company already wrote you an estimate, bring it in. Our second opinion is free.
FAQs
No. As an independent DuraFlex service provider, we use warranty-safe practices and OEM-compatible parts. The warranty covers manufacturing defects, not installation by independent technicians. We document our work with photos so any future warranty claim has a clear maintenance record. Call (331) 202-2419 if you want us to review your warranty terms before booking.
Most single-flue cap replacements take 90 minutes to two hours, including inspection, documentation, and cleanup. Multi-flue or custom-fabricated caps may run half a day if we need to source an oval adapter. We don’t rush the camera verification. You’ll get a written time estimate with your price.
We repair crowns when the spalling is under 3 square feet and no rebar is exposed. If the crack runs full-depth or the crown is sloped toward the flue, we recommend full coating or rebuild. The camera and photos show you which category you’re in before you decide. Call (331) 202-2419 for a free assessment.
We stock common DuraFlex cap sizes and 316Ti storm collars. Less common oval adapters or custom wind-rated caps ship from our Haven network in 2-4 business days. We’ll tell you exactly what’s in stock and what’s not when we write your price, not after you’ve committed.
NFPA 211 recommends annual inspection for all chimney systems, and we agree especially for DuraFlex in Arlington Heights. The freeze-thaw cycle here, combined with clay soil moisture wicking, accelerates crown wear. A cap can look fine from the ground while the storm collar underneath is leaking onto the crown. We find it with the camera, show you the photo, and you decide when to act. Call (331) 202-2419 to schedule.
