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 builds good stainless liners and caps. But Passaic weather does not go easy on anything that sits on top of a chimney, and we have been inside enough DuraFlex jobs since 1999 to know exactly where they break. Here are the failure modes we see most.
- DuraFlex Pro Series cap screen corrosion at the weld points. The Pro Series uses a fine mesh screen tacked to the cap base. In Passaic the combination of wood smoke, rain, and road grit from Route 20 works under those welds within four to six years. The screen sags inward, then the cap starts rattling in high wind. We replace the screen with a heavier aftermarket mesh or swap the crown cap entirely, depending on what the base still has to give.
- Warped crown on DuraFlex Crown Series caps under direct rain and snow. Older Crown Series units have a single-wall top that flexes with heat. On Passaic bungalows with short flue runs, that cap sits closer to the firebox and gets hotter. We find warped crowns that have pulled away from the masonry on one side. Our fix is a Crown Series replacement with a double-wall top, sealed at the mortar line, not just set in place.
- Clearance issues with DuraFlex oval-to-round adapters on older Passaic rowhouses. Gregory Avenue and the blocks around it have chimneys from the 1920s and 1930s, and several were relined with DuraFlex oval kits in the 2000s. The adapter collar at the crown line is a known weak point where the oval meets the round cap. We see rust rings, shifted caps, and occasional bird entry through that joint. We pull the cap, inspect the adapter, and either reseat the collar with a stainless band or replace it before putting a new cap on.
- Failed crown coating over DuraFlex liners on flat-topped chimneys. A lot of Passaic chimneys have near-flat crowns with one or two flue tiles poking through. The crown coating fails first, water gets under the tile, and the DuraFlex liner top plate begins to rust even though the liner itself is fine. We grind the old coating off, repoint any soft mortar, and apply a two-coat crown seal. The liner is rarely the problem. The crown is usually the problem.
- Missing or torn rain collar on DuraFlex SF series caps. The SF line uses a slip-on rain collar that slides over the liner top. We regularly find those collars missing entirely because they were never secured when the liner was installed. In Passaic summers, rain gets between the collar and liner and drains down to the firebox. We install the correct collar, clamp it with stainless, and test the seal before we leave.

What DuraFlex Chimney Cap & Crown Costs in Passaic
Here are the ranges we see most often in Passaic. It is not an estimate for your chimney, but it is a fair window based on many jobs in this county.
| Work | Typical Passaic Price Range |
|---|---|
| DuraFlex chimney cap replacement (standard single flue) | $240 - $380 |
| Multi-flue DuraFlex cap (custom, measured to fit) | $450 - $800 |
| Crown coating (two-coat seal on existing crown) | $350 - $600 |

What moves the price is flue count, roof pitch, and whether the crown masonry still has holding power or needs rebuild work. Condo and rowhouse chimneys along Main Street often have shared flues, which adds time. You will never guess the number. Call (551) 368-8859 and we will work up a free estimate, clear and written, before we touch a single brick.
Why Passaic Homeowners Call Top Hat Chimney for DuraFlex Work
We are not a DuraFlex dealer and we do not claim to be. We are an independent DuraFlex service provider in Passaic, which means you get honest advice without a factory quota behind it. Wendell Pike has been running Top Hat Chimney since 1999 and has put in thousands of hours on Passaic chimneys, including the older rowhouses off Gregory Avenue. You will see his name and license number on every piece of paper we leave behind. This is not a franchise that rotated in last spring. It is a locally owned, owner-operated shop, and Wendell runs into you again on Saturday at the hardware store. We would rather tell you the cap is fine than sell you one. For DuraFlex work, we keep our standards high, and when we back a job with the 90-Day Done Right Promise, it means the cap stays on, the crown stays sealed, and the liner keeps breathing the way it should. We also work regularly with HeatShield and Gelco products when a DuraFlex-only fix is not the right call. Ask anyone on your street.
FAQs
We install and repair DuraFlex products as an independent provider, which means we use OEM parts where warranty coverage applies and quality aftermarket parts where OEM is not necessary. We cannot make DuraFlex’s warranty decisions, but we can document the work with photos and a written report you can submit to DuraFlex. Call (551) 368-8859 and we will walk you through what is covered before we start.
Usually no. The cap and crown are the most exposed parts of the chimney, and they fail first. The liner itself often has years left in it. We inspect the entire run with a camera before recommending any liner work, and we will show you the footage. If the liner is solid, you replace the cap or crown and leave the liner alone. If it is not, we will tell you that too, and we will not oversell you a liner you do not need.
Most Passaic jobs are booked within a few days and completed in one visit. Crown rebuilds can take two visits if the weather works against us. We do not promise same-day service because a proper cap and crown job is not a rushed one, but we will work with you on scheduling and we will show up when we say we will. Call (551) 368-8859 and we will get you on the book.
Once a year, burn or no burn. Chimneys break in the off-season too. In Passaic, the freeze-thaw cycle over the winter works on crown mortar and cap seams even when the fireplace sits cold. A one-time annual check catches a small crack before it becomes a rusted cap or a water-stained ceiling. We will tell you when the work can wait. If it does not need doing, we will say so.
If it is a simple cap swap on a one-story roof, maybe. But if you are on a two-story Passaic rowhouse, working at height with a cap that has wiring or a damaged crown, it is not worth the ladder risk. A cap that is not seated right will grind against the liner top and make the damage worse. Most of the repairs we do after DIY attempts cost more than the original fix would have. Let one of Wendell’s crew take a look. You will get a clear answer and a number, and either way you will know what you are dealing with.
