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 makes a solid liner system, but the cap and crown sit on top of it and take the brunt of Woodland Park’s weather. Here’s what we actually see on roofs in this area, series by series.
- DuraFlex 304L stainless caps corroding at the base seam. This one shows up most on homes near Garret Mountain where wind-driven rain hits caps at an angle. The 304L alloy holds up fine in the flue, but the cap’s welded base is thinner and starts pitting after six or seven years. Water runs down into the liner, and the owner thinks it’s a liner failure. It’s not. We replace the cap and reseal the crown, and the liner stays put.
- DuraFlex AL (aluminum) liner caps crushed by falling branches or ice. The older aluminum-series DuraFlex liners used thinner cap mesh. In Woodland Park’s oak-heavy lots, acorns and small branches dent or tear that mesh, and once it’s torn, birds get in. We swap in a stainless replacea mesh cap and mount it with a proper storm collar.
- Crown spalling on DuraFlex 316L installations due to expansion and contraction. Woodland Park sees real freeze-thaw cycles, and a crown poured too thin over a DuraFlex 316L flue tiles will crack within a few seasons. Water gets into the crown, freezes, and pushes the cap out of square. We repair the crown with a flexible sealant rated for chimney exposure, then reset the cap level.
- Multi-flue DuraFlex caps shifting because the original installer used caulk instead of mechanical fasteners. We see this on older multi-flue jobs where the cap was glued down instead of bracketed. High wind on exposed streets near Rifle Camp Park walks the cap right off the flue. We install the cap with stainless brackets and confirm it’s square before sealing.
- DuraFlex chase covers rusting through where the collar meets the chase top. This is common on factory-built fireplaces where the chase cover is a different gauge than the DuraFlex cap. The seam between them traps water, and the cover rusts from the inside out. We replace the chase cover and install a cap that bolts to it properly, so water sheds instead of pooling.
If it does not need doing, I will tell you that first. We’ve talked plenty of Woodland Park homeowners out of cap replacements because the staining they saw was just surface rust, not structural failure.
Our DuraFlex Chimney Cap & Crown Process
When you call us for DuraFlex cap or crown work, here’s how the job actually goes:
- 1
Call and talk to a live person. Not a call center. Give us the address in Woodland Park and what you’re seeing: water in the firebox, rust on the crown, a cap that looks tilted, or birds in the flue.
- 2
We show up, we inspect, we film it. Wendell and his crew go up on the roof with a camera. We look at the cap, the crown, the chase cover if there is one, and the top of the liner. You get the footage on a screen before we recommend anything.
- 3
We decide OEM vs. aftermarket together. DuraFlex-branded caps are available for most series, but sometimes a quality aftermarket stainless cap with a better warranty makes more sense. We’ll explain the difference in plain English and let you choose.
- 4
We do the repair or replacement. Cap and crown are addressed in the same visit so the top of your system is sealed as one assembly. No return trip needed.
- 5
We test and document. We run a quick smoke test to confirm the flue draws properly, then back the work with our 90-Day Done Right Promise in writing.
- 6
You get a photo report. Before and after shots of the cap and crown, so you know exactly what changed.
What DuraFlex Chimney Cap & Crown Costs in Woodland Park
Here are the numbers we quote most often for DuraFlex work in Woodland Park and the surrounding Passaic County area:
- Standard single-flue stainless cap replacement: $285 to $420, depending on flue size and existing flashing condition.

Why Woodland Park Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been working chimneys in Passaic County since 1999, and more than a few of them were near Rifle Camp Park. Wendell Pike is the name on the company, and he’s the guy who shows up. That means something in a town like Woodland Park, where national chains send a different stranger every time and then vanish when the job disappoints. We install and service DuraFlex, HeatShield, and Gelco products, so we’re not married to one brand’s answer. If a DuraFlex part is the right fix, we use it. If a better aftermarket option exists, we tell you that too. Our 90-Day Done Right Promise is in writing on every job: if it’s not right, one call brings us back. We answer the phone around the clock, give you a straight price before we start, and we’ll run into you again at the hardware store on Saturday.
FAQs
No, using non-DuraFlex caps or sealants typically does not void a DuraFlex liner warranty, since the cap and crown are installation accessories and not liner components. We are an independent DuraFlex service provider and we use parts and materials that meet or exceed the original spec, so your liner coverage stays intact.
Most standard DuraFlex cap sizes are available locally or within a few days, and we keep common sizes on the truck. Custom caps for multi-flue or unusual configurations typically take 5 to 10 business days to fabricate and ship. We’ll give you a straight timeline before we order anything.
If the cracks are hairline and the crown is still structurally sound, a flexible crown coat seals it and buys you years. If sections are spalled or missing, patching won’t hold. We’ll show you the damage on camera and recommend only what’s needed, including telling you when it can wait.
Once a year, burn or no burn. Chimneys break in the off-season too, and the cap and crown are the first things weather hits. An annual inspection catches rust, shifted caps, and crown cracks before they turn into water in the firebox or a damaged liner. Call (973) 846-1622 to schedule your inspection.
Water gets into the crown, freezes, expands, and pushes the cracks wider. That water then runs down into the flue and the top of your DuraFlex liner, which can lead to rust, liner damage, and eventually a chimney that won’t draft safely. A $450 crown coating now beats a $1,500 liner repair later. Call (973) 846-1622 for an exact quote and we’ll be straight about whether it can wait.
