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.

AfterHeatShield Chimney Cap & Crown in Reading: What to Know First
We install, repair, and replace HeatShield chimney caps and crowns for Reading homeowners as an independent HeatShield service provider. Most cap or crown jobs take one visit, and you’ll know the exact price before we start. A typical cap replacement around Reading runs $200 to $650; crown repairs usually land between $350 and $900 depending on what the chimney exposes once we’re up there.
This page is for people who own a HeatShield system – or are considering one – and want straight answers about the cap and crown that protect it. If you’re seeing rust, water stains, spalling brick, or dampness inside the flue, call (484) 209-0837 and Wendell or a member of his crew will walk you through what’s actually going on.
Key Takeaways
- HeatShield caps fail differently than generic caps – we’ll show you the difference with photos.
- Crown cracks are the number one reason HeatShield liners get water damage in Reading.
- We’re an independent service provider – not a HeatShield dealer, so our loyalty is to your chimney, not a parts quota.
- Every job gets the 90-Day Done Right Promise in writing.
- No trip charge inside the county, and a free second opinion on any written estimate you already have.
How HeatShield Products Fail – and How We Fix Them
HeatShield makes good liners and good components, but the cap and crown are the first line of defense. In Reading’s freeze-thaw winters and humid summers, here’s what we see, year after year.
- HeatShield Cease-Fire caps with galvanized bases rusting at the bolt holes. The caps themselves hold up fine, but the steel base plate and mounting bolts corrode within five to eight years in Berks County, especially on homes near the Schuylkill where air carries more moisture. Water then drips straight down onto the flue tile below. We swap the base for a stainless plate and use marine-grade hardware that doesn’t turn to dust.
- Crown cracks that let water behind the HeatShield liner. This isn’t a HeatShield defect – it’s a Reading weather reality. The crown takes rain, snow, ice, and direct sun. When the crown cracks, water works its way down between the clay tile and the HeatShield liner and you get efflorescence on the brick face or a faint damp smell in the firebox. We rebuild or coat the crown before it becomes a liner replacement. A $600 crown repair beats a $3,500 liner job, every time.
- Multi-flue HeatShield caps sized wrong by the last installer. We run into this on older Reading rowhomes with two flues shared under one cap. The cap looks fine from the ground, but it’s leaving one flue half-exposed. HeatShield’s documentation calls for specific clearance, and somebody’s guess left the flue open to rain. We measure, order the right size, and seal it properly.
- HeatShield ceramic caulk failing around the cap base. HeatShield recommends their ceramic-based sealant for cap-to-flue joints, and it goes brittle after a few Reading winters. Once it cracks, wind-driven rain creeps under the cap. We remove the old caulk, clean the surface, and reapply with a fresh bead that flexes instead of shattering.
- Missing or degraded HeatShield spark arrestor mesh. The mesh is rated for the cap but in Reading, squirrels and birds test it daily. A torn mesh screen lets critters nest in the flue, and a blocked flue changes how your whole system drafts. We replace the mesh with HeatShield-compatible stainless screen, not hardware cloth from the aisle at the hardware store.
Our HeatShield Chimney Cap & Crown Process
Here’s how a HeatShield cap or crown job goes when you call Top Hat Chimney.
- 1
You call (484) 209-0837. A live person answers, day or night. We ask what you’re seeing and when it started. We give you an honest range before anyone drives out.
- 2
We inspect. Wendell or a crew member gets on the roof, camera in hand. We photograph the cap, the crown, the flue, and anything else that looks suspicious. You see every picture.
- 3
We explain what’s wrong in plain English. If the cap has five more years in it, we’ll say so. If the crown is cracked but not urgent, we’ll snap the photo and tell you to keep an eye on it. If it needs doing, we show you why. “If it doesn’t need doing, I’ll be the first one to tell you.”
- 4
We agree on a price before tools come off the truck. OEM HeatShield parts when the warranty requires it; quality aftermarket when it doesn’t. You’ll know which one and why.
- 5
We do the work and test it. Cap installed, crown repaired or coated, sealant applied. Then we run a draft test and check for water intrusion paths with a moisture meter.
- 6
You get the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Wendell back. Simple as that.

- Multi-flue HeatShield cap (custom cut): $450 – $750. Older Reading rowhomes with two or three flues fall here.

Why Reading Homeowners Call Top Hat Chimney for HeatShield Work
We’ve been climbing Reading chimneys since 1999. Wendell Pike started this company with a truck, a ladder, and a simple rule: tell people the truth about their chimney, even when the truth is “you don’t need to spend money yet.” That rule has kept us in business for over 29 years while bigger-name outfits have come and gone.
We’re locally owned and owner-operated. The name on the work is the guy you’ll run into at the hardware store on a Saturday. We know HeatShield components because we’ve installed and serviced them for years, and when a job calls for a different brand, we work with DuraFlex and Gelco too. We’re not married to a single manufacturer, so the recommendation you get is based on your chimney, not our inventory.
Every job gets the 90-Day Done Right Promise. Every call gets a live person. And if you already have a written estimate from another company, we’ll give you a free second opinion – no pressure, no obligation. $40 off any repair over $200, and 10% off always for seniors and veterans.
FAQs
No, not if the work is done correctly with compatible parts and proper installation. As an independent HeatShield service provider, we follow the manufacturer’s specs on cap sizing, clearance, and sealant. We use OEM HeatShield parts when the warranty conditions call for them, and we document everything with photos so you have a record if a claim ever comes up. Call (484) 209-0837 and we’ll walk you through exactly what your warranty covers.
If the cap base plate is rusted through, the mounting hardware is corroded, or the spark arrestor mesh is torn beyond patching, replacement is the honest answer. Surface rust and loose bolts can usually be repaired. We’ll show you photos from the roof and tell you which way to go. If it doesn’t need replacing, we’ll say so.
Usually within a few days for non-emergency work. If water is actively getting in and you’re worried about the liner, call (484) 209-0837 and tell us what’s happening. We’ll work you in as quickly as possible, and we’ll give you a real arrival window – not a four-hour guess.
In Reading, it’s almost always freeze-thaw. Water soaks into the crown’s surface, freezes overnight, expands, and cracks the material from the inside. The original crown may also have been poured too thin or without expansion joints. We see this constantly on row homes near Pagoda Hill where chimneys catch the full brunt of northeast storms. We rebuild with a proper crown mix and add flexible sealant that moves with the chimney instead of fighting it.
No. We’re an independent shop, so we service HeatShield along with DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield. That means when we recommend a part or a repair, it’s because it’s the right call for your chimney, not because it’s the only brand we carry.
