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.

Why Top Hat Chimney Is Caernarvon’s Preferred Chimney Cap & Crown Company
Top Hat Chimney has been working Lancaster County stone since 1999, and the chimneys out here are different from what suburban crews see. Caernarvon’s housing stock runs heavily to pre-Civil War fieldstone farmhouses and converted bank barns. Those chimneys were built for open hearths and wide cooking flues, not modern wood stoves. When you call us, you get Wendell Pike, the owner, not a franchise call center. The phone is answered by a live person around the clock, and the number you hear on the phone is the number on the invoice. We publish our license and address, and we back every single job with a written 90-Day Done Right Promise. If it isn’t right, one call brings the crew back at no charge.
Caernarvon residents keep asking the same two questions: will you actually show up, and will the price hold? We will, and it does. We give you a real arrival window ahead of time, and if the schedule slips we call. Ask anyone on your street.
Our Chimney Cap & Crown Services in Caernarvon
Here’s what we actually do when we talk about Chimney Cap & Crown work in Caernarvon. Each job starts with a camera inspection, and you see the footage before we recommend anything.
Cap Installation
Most Caernarvon homes need more than a generic big-box cap. The original fieldstone chimneys on pre-Civil War farms often have oversized or irregular flue dimensions. A standard 13×13 cap slips or leaves gaps that let rain and snow straight into the flue. We measure on site and install the right cap from Olympia Chimney or Famco, sized for your actual flue, with proper fastening that holds up to ridgeline wind exposure on the higher farm lots near Welsh Mountain.

Cap Replacement
We see caps rusted through or blown off after one harsh winter on exposed Caernarvon ridges. If your cap is missing, your flue is taking water every time it rains, period. That water mixes with creosote to form an acid that eats mortar crowns. We pull the old cap, assess what the weather has already done to the crown below, and fit a replacement before the next storm.

Crown Repair
A cracked crown is the most common failure we find in Caernarvon. Freeze-thaw cycles on Mount Airy Road and along Route 23 push water into hairline cracks, then winter expands it into open channels. We remove spalled mortar, patch structural cracks, and seal the crown so water no longer reaches the stonework. If the crown has heaved past saving, we rebuild it to slope water away from the flue, the way it was supposed to be built in the first place.

Crown Coating
For crowns that are still structurally sound but showing surface wear, we apply a Gelco crown coating. This is the right move on many Caernarvon farmhouse crowns where full replacement isn’t yet justified. The coating bonds to the existing mortar, bridges small cracks, and gives you another several years without a teardown. We’re honest about when coating is enough and when it isn’t.

Custom Cap and Multi-Flue Cap
Older Caernarvon stone farmhouses often have two, three, even four flues running through one chimney. Off-the-shelf single-flue caps don’t work. We build custom multi-flue caps that cover the entire crown and direct water away from every termination. This is routine for us here, and it’s one of the biggest differences between a local sweep and a national outfit that sends a technician who has never measured a fieldstone flue.

Trusted Brands We Service in Caernarvon
We install and service products from Olympia Chimney, Famco, and Copperfield, and we stock common replacement parts for Caernarvon jobs so we’re not driving back and forth to a supply house mid-repair. If you have a DuraFlex liner, we work on those too. The point is you get a real manufacturer-backed component, not whatever was on the shelf at a discount store, and we stand behind the installation with our own warranty.
Common Chimney Cap & Crown Problems We See in Caernarvon Homes
- Unlined fieldstone flues glazing creosote fast. Many original Caernarvon farmhouse chimneys were built without any clay tile or metal liner. The wide, cold flue surfaces collect creosote at an accelerated rate, and that creosote acid attacks the mortar crown above it. We see spalling on crowns that looked fine twelve months earlier.
- Year-round wood cookstove firing in the Plain community. Amish and Old Order Mennonite households in Caernarvon run wood cookstoves through summer for baking and canning. That means a chimney swept in April can already show stage-one creosote by August. The crown and cap are cycling hot and cold all year, not just in winter, and hairline cracks turn into open channels in a single season.
- Missing or damaged spark arrestors. Summer canning burns throw embers. If the cap’s spark arrestor screen is torn or missing, those embers land on roof debris or dry nesting material. We replace screens on nearly every cap we touch in Caernarvon for this reason.
- Ridge wind exposure near Welsh Mountain. The elevated farm lots on the ridgeline take more wind than the hollows. Loose cap fasteners, lifted flashings, and crowns eroded by driven rain all show up more often on the high ground. We check seating and fastening on every cap we inspect in Caernarvon, not just the cap itself.

FAQs - Chimney Cap & Crown in Caernarvon
Because the flues were built for open hearths and wide cooking fires, not modern stoves. Standard caps are sized for today’s manufactured flue dimensions, and on an original fieldstone chimney those measurements rarely match. A custom cap sits flat across the oversized opening and sheds water properly, instead of leaving a gap that funnels rain straight into the flue. Call (484) 209-0837 and we’ll measure before we quote.
Yes, and the reason is simple math. Those stoves burn year-round for baking, canning, and daily cooking. The cap and crown go through more hot-cold cycles in one Caernarvon summer than a seasonal fireplace sees in five years. Thermal cycling loosens fasteners and opens hairline cracks faster. Combined with the heavier creosote deposits from continuous wood burning, cap replacement cycles here are shorter than in towns like Wyomissing where wood is a weekend novelty. We account for that when we inspect.
Third-degree creosote is the hard, glossy glaze that forms when creosote concentrates into a dense layer. It’s not brushable. It has to be chemically treated or mechanically removed. For the crown, the problem is that third-degree creosote is acidic and holds moisture against the mortar crown surface, accelerating spalling and cracking. In Caernarvon’s Plain community homes, where cookstoves run daily, we see glaze forming in a single season when it would take suburban homes two or three. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early.
The ridgeline lots sit higher, take more wind, and drop colder at night. More wind means more driven rain hitting the crown from the side, not just falling vertically. Lower temperatures mean freeze-thaw cycles that work water deeper into hairline cracks every winter. The effective burn season stretches longer up there too, because cold air pools in the hollows and heating demand starts earlier and ends later. All of that puts cap fastening and crown sealing under more stress than a sheltered lot in Amity would see.
Yes. Summer baking and canning burns create hot exhaust cycles that stress the cap’s fasteners and screen even in July. The creosote those burns produce sits in the flue through humid August weather, and that acidic, moist environment attacks the crown from below. By fall, a cap that looked fine in April can be rusted through or loosened at the mounting points. We recommend a quick visual check of the cap and crown mid-summer if your stove runs through canning season, not just an annual fall sweep. Call (484) 209-0837 if you’re not sure what you’re looking at.
