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 Reading: What to Know First
If you own a DuraFlex chimney liner or cap system in Reading, we provide independent cap replacement, crown repair, and full waterproofing work, usually completed in a single visit. Typical turnaround is two to five days from your call, and you’ll know the exact price before we start because we don’t do surprises. Most DuraFlex cap and crown jobs around Reading run between $375 and $900 depending on flue count and crown condition.
This page is for homeowners whose DuraFlex cap has rusted through, whose crown is spalling, or who just got told by another company they need thousands in work and want a second set of eyes. That’s what we do. Call (484) 209-0837 and a live person answers.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex aluminum caps with rusted rivets. The standard DuraFlex cap that ships with their liner kits uses aluminum rivets at the collar. Around Reading we see those rivets let go after five or six winters because of the freeze-thaw swings. The cap stays on, but it rattles in the wind and lets rain slip past the collar. We drill out the old rivets, install stainless hardware, and re-seal with high-temp silicone. Takes under an hour and beats replacing the whole cap.
- DuraFlex stainless liner tops with failed chase covers. When the liner is fine but the flat chase cover above it rusts at the seams, water pools and runs down the outside of the DuraFlex pipe. That water sits on the crown and freezes, cracking the concrete. We replace the chase cover with a heavier gauge than what most builders put on, then re-flash around the DuraFlex termination collar.
- Crowns poured too flat on original installs. DuraFlex liners get installed by a lot of crews who never touch the crown. If the crown slope is under two degrees (which we see all over the rowhouses near Pagoda Hill), water doesn’t shed. It pools. We rebuild the crown with a proper slope and a drip edge so water falls away from the DuraFlex termination, not toward it.
- Multi-flue DuraFlex setups with missing or undersized caps. When two or three DuraFlex liners share one chimney, the original cap often only covers the center flue. The unlined flues get capped on the liner itself, but the surrounding crown stays exposed. We fabricate a multi-flue cap that covers the entire footprint, so the whole crown stays dry and the DuraFlex collars never see standing water.
- Crown coating failures on older DuraFlex crown kits. The factory coating on some DuraFlex crown systems looks good for three years and then starts flaking. Underneath, the concrete is already absorbing water. We grind off the old coating, patch the crown with a polymer-modified mix, and apply a breathable siloxane sealer that holds up through Berks County winters.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and book. You call (484) 209-0837. A live person answers, day or night. We ask what you’re seeing; rust, leaks, chunks of concrete in the yard. We give you an arrival window and keep it.
- 2
Inspection with a camera. Wendell or one of his crew gets on the roof and photographs everything: the cap, the crown, the DuraFlex termination, the flashing. You see every photo before we recommend one dollar of work.
- 3
Plain-English verdict. We tell you what can wait, what can’t, and why. If the cap is ugly but functional, we’ll tell you that and shake your hand.
- 4
OEM vs aftermarket decision. DuraFlex OEM caps work fine when they match your liner size. But when the OEM option costs two-thirds of the whole job and a quality stainless replacement does the same thing with a better warranty, we show you both numbers and you choose.
- 5
Repair or replacement. Crown work gets done with a proper slope and a drip edge. Caps get sealed, riveted with stainless, and tested for play. No shortcuts, no half-done flashing.
- 6
The 90-Day Done Right Promise. Every job is backed in writing. If anything isn’t right, one call brings us back, no charge.
What DuraFlex Chimney Cap & Crown Costs in Reading
| Job | Typical Range in Reading |
|---|---|
| Single-flue DuraFlex cap replacement | $375 - $525 |
| Multi-flue cap covering full crown | $600 - $1,100 |

| Full crown rebuild with proper slope | $900 - $1,800 |

What moves the price: how many flues you have, whether the crown slope needs correcting, whether the chase cover is involved, and roof access. A two-story steep roof near Centre Park costs more than a ranch in Muhlenberg. You’ll get an exact number before any work starts, and $40 off any repair over $200.

Why Reading Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been working chimneys around Reading since 1999, and Wendell Pike’s name goes on every job. That means when you call about a DuraFlex cap, you’re talking to someone who has been inside hundreds of local chimneys, not a franchise that rotated in from another state. We’re independent; we don’t answer to DuraFlex’s warranty department, and we’ll tell you when an aftermarket part is the smarter buy. If your chimney also has HeatShield or Gelco components, we work on those too; we don’t get crossed up by mixed systems. And every single job carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. Ask anyone on your street about us.
FAQs
As an independent DuraFlex service provider, we don’t make warranty decisions, but standard cap and crown maintenance doesn’t touch the liner warranty. Replacing a cap or rebuilding the crown above the liner termination is your responsibility as the homeowner, not a warranty item for the liner itself.
If the cap is rusted through or the collar is loose beyond re-sealing, it’s a replacement. If the problem is pitting, a failed rivet, or a bad seal around the collar, we can usually repair it for under $200 and add years of life. We’ll show you photos of what we found before you decide.
Typically within two to five business days. If you’re seeing water stains or hearing a rattling cap in high winds, call (484) 209-0837 and we’ll get you on the schedule. If you’re inside our county, there’s no trip charge.
Yes, as long as it’s properly sized to the liner diameter and rated for your fuel type. A quality stainless cap that fits correctly will do the same job as the DuraFlex OEM part, often with a better warranty. We show you both options and let you pick.
Not always. If the crown is solid with proper slope and no spalling, the cap replacement is clean and fast. If it’s cracked or pooling water, the new cap won’t matter until the crown is fixed. We’ll tell you which one you have, camera footage in hand, every time.
