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 Cap & Crown in Jamaica: What to Know First
We install, replace, and repair DuraFlex chimney caps and crowns in Jamaica as an independent DuraFlex service provider. Most jobs are completed in a single visit, with a written price before any work starts. A standard DuraFlex cap replacement in Jamaica typically runs $385 to $720, and a crown repair or coating lands between $450 and $1,100, depending on what the camera shows. If your flue has a DuraFlex liner and you’re noticing water in the firebox or rust on the damper, call (516) 240-9612 and we’ll get a camera down there.
This page is for homeowners who bought a home with a DuraFlex liner or cap already installed, and for anyone who was quoted a replacement and wants to know whether the price is honest. It’s also for the person who smells dampness in the fireplace and hasn’t been able to figure out where it’s coming from.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316L liner with a rusted rain cap. The liner is stainless, but the cap that shipped with it was often a lower-grade alloy. After five or six Queens winters, the cap pits, the screen rusts through, and birds move in. We replace the cap with a stainless unit sized to the liner, not a universal fit that wobbles in the wind. The fix is straightforward; the mistake we see from other contractors is leaving the old cap base and caulking over it, which fails by the following spring.
- DuraFlex smooth-wall liner with a cracked crown at the throat. This is common in the older row houses near Jamaica Avenue, where the original crown was poured decades ago and the mortar bed has spalled apart. Rain gets behind the liner and tracks down into the smoke chamber. We rebuild the crown with a proper slope away from the flue, and if the liner is still sound, we leave it alone. You’d be surprised how many companies quote a full liner replacement before looking at the crown.
- Multi-flue cap on a DuraFlex dual-liner install. When two DuraFlex liners run side by side, the cap has to span both flues without resting on the crown. We see a lot of caps that were slapped on with sheet-metal screws into the crown top, which cracks it. We size a multi-flue cap that mounts to the flue tiles or a stainless base plate, and we seal it with a flexible crown coating, not silicone.
- DuraFlex liner with a missing or undersized chase cover. On prefab and masonry chases in Jamaica’s split-level homes, the chase cover rusts through and water drips onto the liner insulation. We do a custom stainless steel chase cover with a proper cap opening. The OEM chase cover from DuraFlex is fine, but aftermarket stainless at 22-gauge or thicker often outlasts it. We’ll show you the difference on camera before you spend a dollar.
- DuraFlex cap with a clogged spark arrestor screen. The screen size on many DuraFlex caps is small enough to catch creosote and poplar seed fluff. By late fall, airflow drops, smoke pushes back into the house. We clean the screen on a sweep visit, but if it’s corroded or bent, we replace the whole cap. It’s a $90 part versus a $300 labor call every season. We’ll tell you which one you have, not which one we’d rather sell you.
Our DuraFlex Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers at (516) 240-9612. We book a window, not a vague “sometime this week.” You’ll get a text when the tech is on the way.
- 2
Camera inspection first. We run the camera down the flue before touching anything. Clause 4 of the Haven Standard requires a photo record on every job. You’ll see the crown condition, the cap from below, and the liner surface on screen or in photos after the visit.
- 3
Written price and scope. We hand you a line-item number before any work starts. No “well, it depends.” The price covers the part, the labor, and the coating or sealant if needed.
- 4
Part decision. For DuraFlex work, we use a stainless cap sized to your liner, and if crown repair is needed, we prep and coat with a flexible crown sealer. If a cap is still structurally sound, we tell you and recommend leaving it. We don’t sell parts you don’t need.
- 5
The repair or install. Cap mounting is mechanical, not caulked on. Crown work is scraped, primed, and coated with a slope rated for water runoff.
- 6
Photo report and warranty. You leave with a documented photo record of the finished work and a written warranty under the 365-Day Done Right Promise. If it’s not done right, we make it right.

AfterWhat DuraFlex Chimney Cap & Crown Costs in Jamaica
These are the numbers we put in writing on real Jamaica jobs. They’re honest ranges, not bait.
- Standard stainless cap replacement (single flue): $385 to $550
- Multi-flue cap with base plate: $620 to $980
- Crown repair (partial, with coating): $450 to $750
- Full crown rebuild (tear-out and re-pour): $950 to $1,400
- Chase cover replacement (stainless): $580 to $1,100
What moves the price is access (a third-story roof on a row house costs more than a one-story ranch), the flue count, and whether the crown has to be torn out or just coated. A camera inspection is the only honest way to price it. Free estimates are part of the deal. Call (516) 240-9612 and we’ll give you a number in writing before anything happens.
Why Jamaica Homeowners Call Level Two Chimney Jamaica for DuraFlex Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and every single one started with a written price before we started. That’s not a marketing line; it’s Clause 1 of the Haven Standard, the operating rules we’ve worked under since day one. Our techs are background-checked, uniformed, and they know DuraFlex well enough to tell you when a part is worth saving and when an aftermarket stainless upgrade is better than the OEM component. We also service HeatShield and Gelco products, so if your liner needs sealing or resurfacing while we’re up there, we can handle it in one visit. Corrine Halstead has spent the better part of two decades running inspections across Jamaica, including those older row houses near Jamaica Avenue where the flue work is rarely what the seller’s disclosure says it is. The camera doesn’t negotiate - it just shows what’s there.
FAQs
No. Replacing a rain cap is normal maintenance and does not void the DuraFlex liner warranty. What voids warranties is improper installation: a cap that doesn’t fit, a liner that’s kinked, or sealant that fails and lets water behind the liner. We install caps to manufacturer fitment standards and document every step with photos, so you have a record if DuraFlex ever asks.
You can absolutely replace just the cap. We see companies in Jamaica bundling cap replacement with liner replacement because it’s a bigger ticket. If the camera shows the liner is sound and the crown drains properly, we’ll say so. A cap replacement is a $400 job. Call (516) 240-9612 for a written quote, not a sales pitch.
Most single-flue cap replacements take 45 to 90 minutes on site. Crown repair or coating adds another hour or two depending on the condition. Multi-flue caps and chase covers can run three to four hours. We book one visit, not a mystery timeline, and we text you when the tech is on the way.
Water gets behind the liner, the mortar bed spalls further, and you end up with a rusted damper, water in the firebox, and eventually a smoke chamber rebuild. That’s a $2,000-plus job versus $600 today. The crown is the first line of defense. If the camera shows it’s cracked, fix it now and skip paying for the whole rebuild later.
Yes. We service the DuraFlex 316L and 304 liner systems, their smooth-wall and corrugated lines, and the custom caps and termination kits that came with them. We also work with HeatShield and Gelco products when a liner needs sealing instead of full replacement. Same visit, same written price, same camera report.
If your DuraFlex cap is rusted through or your crown is spalling, call (516) 240-9612. We’ll put a camera down the flue, show you what’s there, and hand you a written price before any work begins. Free estimates, no pressure, just the scope and the number.
