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.
HeatShield Chimney Cap & Crown in Northampton: What to Know First
We repair, replace, and install chimney caps and crowns on HeatShield-equipped chimneys throughout Northampton, PA, usually within one to two weeks of your call. Most cap replacements run $275 to $650 installed, and crown work typically lands between $850 and $2,400 depending on the damage and whether the flue needs rebuilding. You’ll get an exact number before any tool comes off the truck.
This page is for Northampton homeowners who already have HeatShield components – or are considering them – and want honest guidance on caps and crowns that actually protect that investment. If you’re seeing water stains on the ceiling near the chimney, spalling brick, or a cap that’s rusted through, call (484) 859-1367 and we’ll take a look.
How HeatShield Products Fail - and How We Fix Them
HeatShield makes a solid ceramic flue sealant system, but the cap and crown above it are the first line of defense. When those fail, water gets behind the HeatShield coating and starts undoing the work it was installed to do. Here’s what we see on actual HeatShield jobs in Northampton:
- HeatShield Eco-Ceramic flue caps with rusted mounting brackets. The HeatShield coating holds up, but the factory cap bracket attaching to the flue tile corrodes after five or six Pennsylvania winters. Salt air isn’t the issue here; it’s freeze-thaw cycling. We replace the cap and sometimes the top course of flue tile so the new cap has something solid to grab.
- Crowns that were never properly sealed over HeatShield-treated flues. HeatShield seals the inside of the flue, but the crown is a separate pour. If the original crown wasn’t sloped or didn’t overhang the brick, water ponds and seeps down between the flue and the masonry. We rebuild the crown with proper overhang and a bond break so it moves independently from the flue.
- HeatShield Cerfractory treated flues with cracked top tiles. The coating on the interior holds, but the exposed top of the flue tile takes direct weather. Freeze-thaw splits it. We’ll cut the damaged section and install a new tile top or a custom cap that sheds water past the tile edges entirely.
- Multi-flue HeatShield chimneys with undersized factory caps. Homes in Northampton’s older sections – especially the rowhouses near Lincoln Avenue – often have two or three flues in one chimney. The original cap may only cover one. Rain running down the exposed flues erodes the HeatShield surface over time. We fabricate custom multi-flue caps with proper screening and coverage.
- HeatShield Joint Repair lines where the sealant has separated at the flue top. The vertical joints in the top few inches of flue tile take the brunt of weather exposure. We’ve seen HeatShield material crack away there while the rest of the flue stays intact. The fix is local: reapply a compatible refractory sealant at the crown line, then install a cap that keeps standing water off that joint.
Our HeatShield Chimney Cap & Crown Process
Every HeatShield job here follows the same path, whether it’s a cap swap or a full crown rebuild:
- 1
Talk it through. You call, we talk about what you’re seeing – water stains, rust flakes in the firebox, cap lying in the yard after a windstorm. A live person answers. It might be Wendell.
- 2
Get on the roof. We inspect the cap, crown, and the top course of flue tile. We photograph everything. If it’s a crown issue, we check the flue interior with a camera to see if the HeatShield coating is still intact below the damage line.
- 3
Plain-English verdict. You see the photos. We tell you what’s actually failing, what can wait, and what needs doing now. If the cap is ugly but functional, we’ll say so.
- 4
Parts decision. For caps, we use quality aftermarket stainless or copper that meets or exceeds the original spec. For crown work, we pour fresh concrete with proper slope, overhang, and a flexible bond break at the flue. If the flue tile itself needs work, we repair it before the crown goes on.
- 5
The repair. Cap installs are usually done in one visit. Crown rebuilds need a couple of days for the concrete to cure properly. We tarp and protect the roof while we work.
- 6
Test and walk you through it. We run water where we can, check the fit, and show you the finished work. Every job carries our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back.

Why Northampton Homeowners Call Top Hat Chimney for HeatShield Work
We’ve been doing this since 1999. Wendell Pike started Top Hat Chimney because he got tired of watching national outfits send a different face every season and change the number at the door. The person who shows up for your HeatShield job is background-checked, in uniform, and answers to a name you can find on the side of the truck.
We work as an independent HeatShield service provider. That means we can tell you plainly when a repair makes sense and when you’d be better off leaving the existing cap alone. We also service DuraFlex and Gelco products, so if your HeatShield chimney has mixed-brand components, we can handle the whole thing without bouncing you between companies. The 90-Day Done Right Promise is on every job in writing. Ask anyone on your street.
FAQs
No. HeatShield warranties cover the ceramic coating applied to the flue interior. Cap and crown work happens above and around that surface, and proper cap installation actually protects your warranty position by keeping water from undermining the coating. As an independent provider, we’re careful to work without disturbing the HeatShield material below the flue top.
If the cap is rusted through, missing screens, or no longer covers the flue opening, it’s a replacement. If it’s just loose or the mesh is torn, we can often repair it for less. The camera footage and a plain-English verdict – every time, no exceptions. Call (484) 859-1367 and we’ll take a look.
One day to strip, form, and pour. Two to three days of curing before it’s fully weathertight. We schedule around the forecast so rain doesn’t mess with the pour. In Northampton’s freeze-thaw climate, rushing the cure is how you get a crown that cracks in its first winter.
On a multi-flue HeatShield chimney, yes. Stock caps rarely cover every flue, and the uncovered flue takes direct water that eats at the HeatShield surface over time. On a single flue with standard dimensions, a quality stock cap works fine and saves you money. We’ll tell you which one your chimney actually needs, not which one makes the bigger invoice.
Depends on the damage. If the top course of tile is cracked but sound, we can often install the cap with a custom mounting bracket that bypasses the weak section. If the tile is collapsed or crumbling, that needs repair first – a cap mounted to failed tile will just come loose in the first storm. Call (484) 859-1367 and we’ll put eyes on it.
If it does not need doing, we will tell you. If it does, we will get it done right.
