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 Quincy: What to Know First
DuraFlex chimney cap and crown work in Quincy typically runs between $180 and $650 depending on whether we’re repairing a crown, replacing a cap, or fabricating something custom for an older flue. Most jobs are done in a single visit, and we quote the price before any tool comes off the truck. You’ll know exactly what it costs before we start.

This page is for Quincy homeowners who own a DuraFlex liner system or DuraFlex cap and want someone who actually knows how that hardware behaves after a few New England winters. Call (781) 277-4630 and Wendell or his crew will walk you through what you’re seeing.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex Pro stainless cap screens clogging with creosote glaze. The fine mesh on DuraFlex Pro caps does its job keeping birds out, but on wood-burning flues it collects creosote faster than homeowners expect. We see this constantly in Quincy colonials where people burn a lot of pine. The fix is usually a deeper cleaning of the mesh plus a conversation about burn habits, not a new cap.
- Reliance series caps loosening at the clamp band. The Reliance line uses a band-clamp attachment that can work loose after a few freeze-thaw cycles on exposed Quincy rooftops. The cap stays on, but it rattles and shifts. We pull it, clean the mating surface, re-seat the band, and torque it properly. Half the time the cap itself is fine.
- DuraFlex crown rust-through on the rain skirt. The galvanized rain skirt on some older DuraFlex caps rusts along the bottom edge where water pools. You’ll see orange streaking down the side of the cap. If the cap body is still sound, we’ll rebuild the skirt rather than sell you a whole new unit.
- Improper liner-to-cap fit from previous installs. This one’s common. A previous company installs a DuraFlex liner, then slaps on a generic cap that doesn’t seat right. The result is water getting between the liner and the flue tile. We see this all over Merrymount and Wollaston. Our fix is a proper DuraFlex-compatible cap sized to the liner, sealed with a heavy-gauge bead of CrownCoat at the joint.
- Crown spalling from trapped moisture. On masonry chimneys with a DuraFlex liner, the clay crown on top of the brick can still spall and crack. The liner protects the flue, but the crown is exposed. In Quincy, the answer is usually CrownCote, our thick brush-on crown sealant, applied over a prepared crown with a bonder. That crown will outlast the next few winters.
Our DuraFlex Chimney Cap & Crown Process
- 1
You call, a person answers. No phone tree. Wendell or one of his crew takes the call, asks about what you’re seeing, and books a time that works. You get a real arrival window.
- 2
We inspect from the roof. The sweep who shows up climbs up and photographs the cap, crown, liner top, and flashing. If it’s not safe to walk the roof, we’ll tell you and use a drone or ladder work instead.
- 3
You see the camera footage. When the cap or crown looks questionable, we run the chimney camera so you can see exactly what’s failing. No camera, no recommendation. That’s the rule.
- 4
We tell you the truth about OEM vs. aftermarket. Some DuraFlex caps are worth replacing with genuine DuraFlex parts. Others are simple enough that a quality aftermarket cap from Gelco or Famco does the job for less. We’ll tell you which is which and why. We’re not married to the DuraFlex label. You shouldn’t be either.
- 5
The repair or replacement happens same visit, or we schedule it. Most cap and crown work is done on the spot. Custom multi-flue caps take a week or so to fabricate. Either way, you’ll have the price in writing before anything starts.
- 6
We test and show you the work. After a cap replacement, we verify the draft with a smoke pull test. After a crown repair, we show you the sealed surface. Then we walk the property with you so there’s no mystery left.
What DuraFlex Chimney Cap & Crown Costs in Quincy
Here’s what we typically see in Quincy, no hidden add-ons:
- Cap reseating and band re-torque: $180-$240. The cap is fine. The attachment isn’t.
- Single-flue cap replacement (DuraFlex Pro or equivalent aftermarket): $280-$450 installed.
- Custom multi-flue cap for two or three flues: $500-$800 depending on flue size and material gauge.
- CrownCote crown sealing (standard residential crown): $275-$500 including all prep and bonding.
- Crown rebuild with washing and crown form: $500-$900 if the old crown is too far gone to save.
What moves the price is flue size, roof pitch, and whether you need a custom sheet-metal cap. What doesn’t move it is surprise fees. The number you hear on the phone is the number on the invoice. Call (781) 277-4630 for a free estimate. We don’t charge a trip fee inside our service county.
Why Quincy Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been climbing onto Quincy roofs since 1999. Wendell Pike started this company as a one-man operation, and it’s still owner-operated today. When you call, you talk to a person. When the job runs long, you know who to blame. When it’s done right, you’ll see the same face next year. That matters to people who’ve been burned by a national outfit that quoted one price on the phone and another at the door.
Every DuraFlex cap and crown job carries our 90-Day Done Right Promise in writing. If it’s not done right, one call brings us back at no charge. We also stock and service HeatShield and Gelco products, so if your DuraFlex crown or cap sits next to other brand components on the same flue, we don’t have to tell you to call someone else. Seniors and veterans get 10% off, always. Bring us a competing written estimate and we’ll give you a free second opinion. Ask anyone on your street.
FAQs
No, not if the cap is properly sized and installed to the liner’s specification. As an independent DuraFlex service provider, we’re not authorized by the manufacturer, but we follow their install specs closely and use OEM parts when it makes sense. If the cap is still within warranty and the failure is a manufacturing defect, we’ll tell you to file a claim before spending your money with us. If it’s just old, we’ll fix it.
You usually don’t, until someone gets on the roof and looks at the clamp band and screen condition. In Quincy, we find that most loose caps are fine after a re-torque of the band clamp on the Reliance series. If the mesh is rusted through or the rain skirt is failing, replacement is the honest answer. We’ll show you the photos either way.
Yes. The cap and liner don’t have to come from the same manufacturer. We’ll size the cap to the liner’s inner and outer diameter, not the brand name printed on the side. That’s why we stock Famco, Gelco, and Copperfield caps alongside DuraFlex. The flue doesn’t care what label is on the cap. It cares about fit and seal.
If you call us in September or October, we can usually get a standard crown sealed within a week. Custom cap fabrication takes longer, typically ten days to two weeks. The freeze-thaw cycles in Quincy start doing real damage by November, so the earlier you call, the cheaper the fix tends to be. Call (781) 277-4630 and we’ll give you an honest timeline.
Water keeps working into the crown, freezes, and cracks more of it. Eventually it reaches the brickwork below and starts spalling the top courses of the chimney. The repair that was a $300 crown seal becomes a $1,500 crown rebuild plus brick work. A crown is cheap compared to what sits underneath it. If it doesn’t need doing, we’ll tell you that too. But if it does, waiting just makes it worse.
